Environmental correlates of stem radius change in the endangered Fitzroya cupressoides forests of southern Chile Agricultural and Forest Meteorology Many megacities and large urban agglomerations are located in the coastal zone where land, atmosphere, and ocean meet, posing multiple environmental challenges which we consider here.
The atmospheric flow around megacities is complicated by urban heat island effects and topographic flows and sea breezes and influences air pollution and human health. The outflow of polluted air over the ocean perturbs biogeochemical processes. Contaminant inputs can damage downstream coastal zone ecosystem function and resources including fisheries, induce harmful algal blooms and feedback to the atmosphere via marine emissions.
The scale of influence of megacities in the coastal zone is hundreds to thousands of kilometers in the atmosphere and tens to hundreds of kilometers in the ocean. We list research needs to further our understanding of coastal megacities with the ultimate aim to improve their environmental management. Nevertheless, little is known about which heritable seed traits are functional to the main signals of fire heat and smoke , thus having the potential to evolve. Here, we explored whether three seed traits pubescence, dormancy and shape and fire regime modulate seed response to fire cues heat and smoke.
As a model study system, we used Helenium aromaticum Asteraceae , a native annual forb from the Chilean matorral, where fires are anthropogenic. We related seed trait values with fitness responses germination and survival after exposure to heat-shock and smoke experimental treatments on seeds from 10 H. We performed a phenotypic selection experiment to examine the relationship of seed traits with post-treatment fitness within a population adaptive hypothesis. We then explored whether fire frequency in natural habitats was associated with trait expression across populations, and with germination and survival responses to experimental fire-cues.
We found that populations subjected to higher fire frequency had, in average, more rounded and pubescent seeds than populations from rarely burned areas. There was correlated selection on seed traits: pubescent-rounded or glabrouscent-elongated seeds had the highest probability of germinating after heat-shock treatments. Seed pubescence and shape in H. Our results provide new insights into the process of plant adaptation to fire and highlight the relevance of human-made fires as a strong evolutionary agent in the Anthropocene. In fires burned. As then, the fires have stirred public, political and scientific concern.
The objectives of the study were to determine main tree-fall gap attributes and to assess tree recruitment and growth patterns in tree-fall gaps of two mid-elevation Andean old-growth forests. We measured the canopy and expanded area of each gap, and for the gap-maker species we measured its diameter at breast height dbh , felling direction and type of treefall.
In each gap, tree seedlings, saplings and bamboo culms were counted in subplots. Increment cores of potential successors were obtained to examine growth patterns. Most gaps were originated by wind-snap and upturned root-plates of all the major tree species Laureliopsis philippiana, Saxegothaea conspicua and Dasyphyllum diacanthoides, and Nothofagus dombeyi in NF. The understory species Chusquea culeou was an important competitor in gaps, especially in STF where the bamboo was more effective inhibiting the recruitment of tree seedlings.
The successful recruitment of shade-tolerant tree species beneath endogenous tree-fall gaps indicates that these species follow a gap-phase regeneration mode through which -after several growth releases- they can reach the main canopy. These studies could offer valuable insights for the urgently required restoration and management of Andean old-growth forests.
Stakeholder participation in building resilience to disasters in a changing climate Environmental Hazards In south-central Chile, second-growth forests include those dominated by Nothofagus obliqua , N. This article examines the influence of fire and logging on the establishment patterns and development of second-growth forests in south-central Chile. We characterize the size structure and composition of these four types of forests with sampling plots. The identification of the type of disturbance and its date of occurrence was determined from evidence such as fire scars and even-aged pulses of tree establishment.
The size, structure and species composition of these forests indicate an intermediate state of development with an average density and basal area ranging from to trees ha -1 and from 59 to 85 m 2 ha -1 , respectively. In the Mixed Evergreen second-growth forests, mid-shade or shade tolerant species e. Fires and logging have been pervasive factors in determining the structural and compositional uniformity of the native forests of south-central Chile.

Weaddress the specific case of adding or removing stations, and the more general situation of optimally distributing a given number of stations in a domain taking into account transport patterns and spatial factors such as population density and emission patterns. Weconsider three quality indicators: precision gain, information gain and degrees of freedom for a signal. These metrics are all functions of the singular values of the sensitivity matrix that links emissions and observations in the variational framework.
Weillustrate the application of the methodology in the case of Santiago Wedeem information gain as the best of the above indicators for this case. The application is restricted to diurnal and summer conditions, for which the dispersion model shows a good agreement with observations. The current method offers advantages in that it allows extending a network to include new sites, and it explicitly considers the effects of dispersion patterns, and desired weighting functions such as emission fluxes and population density. Still, according to our results, the current configuration could be improved by integrating more suburban stations in the southwest of the basin.
A correlated shortening of the North and South American monsoon seasons in the past few decades Climate Dynamics The presence of 26 tephras throughout the record allows examination of the relationship between explosive volcanism and vegetation change under contrasting climatic states of the Holocene. Our results indicate a primary role of climate change as driver of long-term vegetation change and as a modulator of vegetation responses to volcanic disturbance at multidecadal and centennial timescales.
Projected strengthening of Amazonian dry season by constrained climate model simulations Nature Climate Change To assess the diversity in forecast capability among the models, the analysis was extended to wind field both surface and profile , synoptic conditions, emissions and deposition fluxes.
Models predict the onset and evolution of the AOD for all analysed lead times. On average, differences among the models are larger than differences among lead times for each individual model. In spite of large differences in emission and deposition, the models present comparable skill for AOD. In general, models are better in predicting AOD than near-surface dust concentration over the Iberian Peninsula.
Models tend to underestimate the long-range transport towards northern Europe. Our analysis suggests that this is partly due to difficulties in simulating the vertical distribution dust and horizontal wind. Differences in the size distribution and wet scavenging efficiency may also account for model diversity in long-range transport.
Anthropogenic and natural contributions to the Southeast Pacific precipitation decline and recent mega-drought in central Chile Geophysical Research Letters The forcing and feedback parameters of the net energy flux, as well as its different components at the top-of-atmosphere TOA and surface, were examined in 10 Earth System Models to better understand the impact of solar radiation management on the energy budget.
In spite of their very different nature, the feedback parameter and its components at the TOA and surface are almost identical for the two forcing mechanisms, not only in the global mean but also in their geographical distributions. This conclusion holds for each of the individual models despite intermodel differences in how feedbacks affect the energy budget. This indicates that the climate sensitivity parameter is independent of the forcing when measured as an effective radiative forcing.
We also show the existence of a large contribution of the cloudy-sky component to the shortwave effective radiative forcing at the TOA suggesting rapid cloud adjustments to a change in solar irradiance. In addition, the models present significant diversity in the spatial distribution of the shortwave feedback parameter in cloudy regions, indicating persistent uncertainties in cloud feedback mechanisms.
Modelled glacier equilibrium line altitudes during the mid-Holocene in the southern mid-latitudes Climate of the Past Landscape ecology has an enormous contribution to make to this field, and one could argue, uniquely so. Tools developed or adapted for landscape ecology are being increasingly used to assist with the quantification, modelling, mapping, and valuing of ecosystem services.
Several of these tools and methods encased therein are described among the eleven papers presented in this special issue, and their application has the potential to facilitate the management and promotion of services within ecosystems. Papers are associated with each of the four key categories of services that ecosystems provide to humans: supporting, provisioning, regulating, and cultural.

The papers represent work conducted in eleven different countries, especially from South America. Each carries a unique approach to address a particular question pertaining to a particular set of ecosystem services. These studies are designed to inform and improve the economic, environmental and social values of the ecosystem services. This knowledge should help to develop new management alternatives for sustaining and planning ecosystems and the services they provide at different scales in space and time.
We believe that these papers will create interest and inform management of some potential methods to evaluate ecosystem services at the landscape level with an integrative approach, offering new tools for management and conservation. Evaluation of impacts of management in an anthropogenic peatland using field and remote sensing data Ecosphere One of the most significant challenges for the construction of these lists is the gathering and availability of the information needed to apply the criteria. We present a complement to the IUCN's methodology to assess the threat level to ecosystems, estimating the spatial and temporal quality of the information available in scientific publications.
We did this by applying the IUCN criteria to determine the threat level to the sclerophyll ecosystems of central Chile. Spatially explicit studies that identify disturbances in the structure of the vegetation were selected, making it possible to quantify effectively the reduction in the ecosystems' distribution. The spatial and temporal quality of the assessment were estimated as the percentage of the potential ecosystem distribution and the time frame recommended by the IUCN 50 years , that the studies represented for each ecosystem.
The influence of anoxia and substrate availability on N2O cycling by denitrification in the upper boundary of the oxygen minimum zone off northern Chile Journal of Marine Research In this article, we analyse the differences of mean of annual and austral-summer DJF temperature, precipitation, and sea-level pressure SLP over South America SA between and , and explore the occurrence of significant shifts in their time series.
Our sources are instrumental records, gridded interpolated data, and reanalyses. Although major regional differences in the intensity of the signal are detected, the climate shift is identified in all variables. This latter feature may have partly induced the rapid warming observed along the tropical-extratropical west coast of the continent through the weakening of the cold Humboldt current system. The presence of 30 tephras throughout the record attest for the proximity of the site to active volcanic centres and allows assessment of the role of volcanic disturbance on past vegetation and fire regime shifts.
We interpretalternations in dominance between North Patagonian and Valdivian rainforests driven by changes in temperature and precipitation of westerly origin at multi-millennial and millennial timescales. Comparisons with palynological records having similar span, time resolution and age control suggest that regional climate has played a central role on the establishment, composition and maintenance of temperate rainforests. This influence is overprinted by disturbance regimes at the local and landscape level, driving divergences and heterogeneity especially at times of relatively weak climatic forcing.
Raga, G. Forest cover loss is primarily attributable to fire, logging, and conversion of native forest to agriculture, pasture, and forest plantations, and types of change vary within and among the many diverse types of forests in South America. Major changes in forest cover and growing policy concerns underscore an urgent need for research on sustainable forest management and water ecosystem services in South America. Differences in land ownership and management objectives create trade-offs between wood production and water ecosystem services from forests. Work is needed to quantify how forest change and management affect ecosystem services, such as wood production versus water provision.
Current scientific understanding of forest management effects on water ecosystem services in South America has important limitations, including a scarcity of long-term records and few long-term integrated watershed studies. Industry, government, universities, and local communities should collaborate on integrated applied studies of forests and water. Data archiving and publically available data are required. The creation of national networks and a multi-country South America network to identify and implement common water research protocols, share results, and explore their implications would promote common and well-supported policies.
Hydrologists working in South America are well placed to tackle the challenges and opportunities for collaborative research that will maintain the intrinsic values and water ecosystem services provided by South America's forests. Human impacts and aridity differentially alter soil N availability in drylands worldwide Global Ecology and Biogeography In this carbon cycle-climate model intercomparison project, which spans the full model hierarchy, we quantify responses to emission pulses of different magnitudes injected under different conditions. The CO2 response shows the known rapid decline in the first few decades followed by a millennium-scale tail.
The response in global mean surface air temperature is an increase by 0. Our best estimate for the Absolute Global Warming Potential, given by the time-integrated response in CO2 at year multiplied by its radiative efficiency, is The integrated CO2 response, normalized by the pulse size, is lower for pre-industrial conditions, compared to present day, and lower for smaller pulses than larger pulses. In contrast, the response in temperature, sea level and ocean heat content is less sensitive to these choices. Although, choices in pulse size, background concentration, and model lead to uncertainties, the most important and subjective choice to determine AGWP of CO2 and GWP is the time horizon.
Spatio-temporal analyses of wildfires in the region of Maule, Chile Bosque Such conditions are more commonly expected at sites at much higher altitude such as ALMA on the Chajnantor plateau m asl or otherwise particularly dry sites such as locations in Antarctica. We provide a full account ofthe measurements of PWV and other relevant atmospheric parameters.
An explanation of the observed conditions is given in terms of the prevailing meteorological pattern. Presence of nitrous oxide hotspots in the coastal upwelling area off central Chile: an analysis of temporal variability based on ten years of a biogeochemical time series Environmental Research Letters Based on metric variables the fossils are temporarily asigned to cf. We present and discuss some taphonomic processes occurring within the site, starting from the study of the marks observed in the surface of the fossils, wich are consistent with the bog environment with occasional fluvial flooding described for the site.
Temporal and spatial variability of biological nitrogen fixation off the upwelling system of central Chile To date, we rely on climate models for estimates of dust fluxes to calculate the impact of airborne micronutrients on biogeochemical cycles. A comparison with dust flux simulations highlights regional differences between observations and models. By forcing a biogeochemical model with our new data set and using this model's results to guide a millennial-scale Earth System Model simulation, we calculate the impact of enhanced glacial oceanic iron deposition on the LGM-Holocene carbon cycle.
Here, we present data sets of glacial-interglacial dust-supply cycles from the largest Southern Ocean sector, the polar South Pacific, indicating three times higher dust deposition during glacial periods than during interglacials for the past million years. Although the most likely dust source for the South Pacific is Australia and New Zealand, the glacial-interglacial pattern and timing of lithogenic sediment deposition is similar to dust records from Antarctica and the South Atlantic dominated by Patagonian sources. These similarities imply large-scale common climate forcings, such as latitudinal shifts of the southern westerlies and regionally enhanced glaciogenic dust mobilization in New Zealand and Patagonia.
Photosynthetic responses of trees in high-elevation forests: Comparing evergreen species along an elevation gradient in the Central Andes. AoB plants Recent developments in coherent ice core chronologies now enable us to depict with a precision of a few centuries the relationship between climate records in Greenland and Antarctica over the millennial scale variability of the Last Glacial period. Stacks of Greenland and Antarctic water isotopic records nicely illustrate a seesaw pattern with the abrupt warming in Greenland being concomitant with the beginning of the cooling in Antarctica at the Antarctic Isotopic Maximum AIM.
In addition, from the precise estimate of chronological error bars and additional high resolution measurements performed on the EDC and TALDICE ice cores, we show that the seesaw pattern does not explain the regional variability in Antarctic records with clear two step structures occurring during the warming phase of AIM 8 and Our Antarctic high resolution data also suggest possible teleconnections between changes in low latitude atmospheric circulation and Antarctic without any Greenland temperature fingerprint. Large fires in the Andean Araucaria forests: when a natural ecological process becomes a threat Oryx It drains an international basin of 29,km2 shared by Chile and Argentina and has a high ecologic and economic value including conservation, tourism, recreational fishing, and projected hydropower.
This study reconstructs the austral summer - early fall January-April streamflow for the Baker River from Nothofagus pumilio tree-rings for the period Summer streamflow represents Tree-fall gaps and patterns of tree recruitment and growth in Andean old-growth forests in south-central Chile Bosque Paradoxically, mapping approaches meant to inform policy decisions focus on the magnitude and spatial distribution of the biophysical supply of ES, largely ignoring the social mechanisms by which these services influence human wellbeing.
If social mechanisms affecting ES demand, enhancing it or reducing it, are taken more into account, then policies are more effective. By developing and applying a new mapping routine to two distinct socio-ecological systems, we show a strong spatial uncoupling between ES supply and socio-ecological vulnerability to the loss of ES, under scenarios of land use and cover change.
Public policies based on ES supply might not only fail at detecting priority conservation areas for the wellbeing of human societies, but may also increase their vulnerability by neglecting areas of currently low, but highly valued ES supply.

ENSO exhibits considerable natural variability at interdecadal-centennial timescales5. Instrumental records are too short to determine whether ENSO has changed6 and existing reconstructions are often developed without adequate tropical records. Here we present a seven-century-long ENSO reconstruction based on 2, tree-ring chronologies from both the tropics and mid-latitudes in both hemispheres. The inclusion of tropical records enables us to achieve unprecedented accuracy, as attested by high correlations with equatorial Pacific corals and coherent modulation of global teleconnections that are consistent with an independent Northern Hemisphere temperature reconstruction9.
Our data indicate that ENSO activity in the late twentieth century was anomalously high over the past seven centuries, suggestive of a response to continuing global warming. Climate models disagree on the ENSO response to global warming , suggesting that many models underestimate the sensitivity to radiative perturbations. Illustrating the radiative effect, our reconstruction reveals a robust ENSO response to large tropical eruptions, with anomalous cooling in the east-central tropical Pacific in the year of eruption, followed by anomalous warming one year after.
Our observations provide crucial constraints for improving climate models and their future projections. Analysis and optimal design of air quality monitoring networks using a variational approach Tellus B: Chemical and Physical Meteorology The collapse of human societies is a complex phenomenon where historical and cultural dimensions play a key role, and they may interact with the environmental context.
However, the importance of the interaction between socio-economic and climatic factors in explaining possible breakdowns in Native American societies has been poorly explored. Our motivation is to demonstrate that simple population dynamic models can be helpful in understanding the causes and relative importance of population changes in Andean agro-pastoral societies in responses to socio-environmental variability. Simple logistic models that combine the effects of external socio-economic causes and past rainfall variability inferred from Gross Domestic Product [GDP] and tree-rings, respectively were quite accurate in predicting the sustained population decline of the Aymara people.
This study constitutes an example of how applied ecological knowledge, in particular the application of the logistic equation and theories pertaining to nonlinear population dynamics and exogenous perturbations, can be used to better understand major demographic changes in human societies.
These forests are also keys for social welfare as a result of their supply of timber as well as ecosystem services. Forests in the ecoregion have been extensively converted to fast growing Pinus radiata and Eucalyptus spp. This study describes the results of detailed measurements of hydrology and stream water chemistry in eight small watersheds in south central Chile, subjected to replacement of native temperate rainforest by exotic Eucalyptus plantations.
In this system, watersheds have streamside buffers of native forest SNFW with varying widths. Results indicate that retention of SNFW counteracts hydrologic effects of Eucalyptus plantations, which are widely known to reduce water yields. In addition, a decrease in the concentrations of total nitrogen, dissolved inorganic nitrogen DIN , nitrate-N, and different sized fractions of particulate organic matter were found in streams draining these plantations as a function of increasing SNFW. The findings from this study suggest that SNFW may significantly reduce adverse effects from exotic species forestry plantations on water provision in an area of south central Chile where exotic forest plantations are rapidly expanding.
However, the conservation of biodiversity in a quickly changingworld is a challenging task which requires cost- efficient and precise monitoring systems. In the present study, the suitability of airborne discrete-return LiDAR data for the mapping of vascular plant species richness within a Sub-Mediterranean second growth native forest ecosystemwas examined.
The vascular plant richness of four different layers total, tree, shrub andherb richness was modeled using twelve LiDAR-derived variables. As species richness values are typically count data, the cor- responding asymmetry and heteroscedasticity in the error distribution has to be considered. Both models were coupled with a feature selection approach to identify the most relevant LiDAR predictors and keep the models parsimonious. The results of RF and GLM agreed that the three most im- portant predictors for all four layers were altitude above sea level, standard deviation of slope and mean canopy height.
Thiswas consistent with the preconception of LiDAR's suitability for estimating species richness,which is its capacity to capture three types of information: micro-topographical, macro-topographical and canopy struc- tural. Generalized LinearModels showed higher performances r2: 0. Furthermore, the results of the best GLMweremore parsimonious three predictors and less biased than the best RFmodels twelve pre- dictors. We think that this is due to the mentioned non-symmetric error distribution of the species richness values, which RF is unable to properly capture.
Fromanecological perspective, thepredicted patterns agreedwell with theknown vegetationcomposition of the area. We found especially high species numbers at low elevations and along riversides. In these areas, overlap- ping distributions of thermopile sclerophyllos species,water demanding Valdivian evergreen species and species growing in Nothofagus obliqua forests occur. The three main conclusions of the study are: 1 appropriatemodel selection is crucialwhenworkingwith biodiver- sitycountdata; 2 the applicationofRFfordatawithnon-symmetricerrordistributions isquestionable; and3 struc- tural and topographic information derived fromLiDAR data is useful for predicting local plant species richness.
The AAIW past variability is poorly understood mainly due to the lack of sedimentary archives at intermediate water depths. Effects of light and phosphorus on summer DMS dynamics in subtropical waters using a global ocean biogeochemical model Environmental Chemistry An attribution assessment identified precipitation variability as the dominant forcing modulating annual mass balances at ECH, with temperature variations likely playing a secondary role. Similar trends observed in other shorter glacier mass-balance series suggest that the Echaurren Norte glacier reconstruction is representative of larger-scale conditions and could be useful for more detailed glaciological, hydrological and climatological assessments in this portion of the Andes.
Different times, same story: Native forest loss and landscape homogenization in three physiographical areas of south-central of Chile Applied Geography The major conclusion of the first appraisal of prognostic ocean DMS models was that such models need to give more weight to the direct effect of environmental forcings e. Here, the relative role of light and phosphorus on summer DMS dynamics in subtropical waters is assessed using the ocean general circulation and biogeochemistry model NEMO-PISCES in which macronutrient concentrations were restored to monthly climatological data values to improve the representation of phosphate concentrations.
Results show that the vertical and temporal decoupling between chlorophyll and DMS concentrations observed in the Sargasso Sea during the summer months is captured by the model. Additional sensitivity tests show that the simulated control of phosphorus on surface DMS concentrations in the Sargasso Sea is much more important than that of light. By extending the analysis to the whole North Atlantic Ocean, we show that the longitudinal distribution of DMS during summer is asymmetrical and that a correlation between the solar radiation dose and DMS concentrations only occurs in the Sargasso Sea.
The lack of a widespread summer DMS paradox in our model simulation as well as in the comparison of discrete and climatological data could be due to the limited occurrence of phosphorus limitation in the global ocean. Linking the concept of multifunctionality with the ecosystem services ES approach offers a promising avenue for producing scientific evidence to inform landscape planning, e. However, the value for decision-making of ES-based multifunctionality assessments has been constrained by a significant conceptual and methodological dispersion.
To contribute towards a cohesive framework for landscape multifunctionality, we analyse case studies of joint ES supply regarding ten criteria designed to ultimately answer four aspects: i the multifunctionality of what e. We constructed a typology of methodological approaches based on scores for criteria describing the evaluation method and the level of stakeholder participation in assessments of joint ES supply.
Surveyed studies and underlying types of methodological approaches spatial, socio-spatial, functional, spatio-functional differed in most criteria. We illustrate the influence of methodological divergence on planning recommendations by comparing two studies employing contrasting approaches spatial and functional to assess the joint supply of wildlife habitat and agricultural production in the Argentine Chaco.
We distinguish between a pattern-based and process-based multifunctionality, where the latter can only be detected through approaches considering the ecological processes e. Finally, we propose an integrated approach for assessing a socially-relevant process-based multifunctionality. Radiocarbon chronology of the last glacial maximum and its termination in northwestern Patagonia Quaternary Science Reviews The SEP is characterized by strong coastal ocean upwelling, the coldest sea surface temperatures SST at comparable latitudes, the planet's most extensive subtropical stratocumulus deck, and a high and steep cordillera to the east.
Mapping of ecosystem services: Missing links between purposes and procedures Ecosystem Services Nevertheless, a broader understanding of common patterns and variability of LULC over the entire range of the hotspot is lacking. We performed a complete review of the different studies reporting LULC changes and performed a joint analysis of their results using an integrated comprehensive approach. We related the variation of LULC change to latitude, time period and vascular plant richness using generalized linear models. Overall, there were nine studies, which covered The highest net forest loss was observed in the — period.
This decreased in the — period and rose again in the — period. This result reveals a continuous forest loss in the last 40 years. However, in the area of greatest species richness native forests are mainly converted to exotic tree plantations. Chilean forestry model has proved successful in expanding exotic tree plantation, but so far it has not been compatible with native forest conservation and restoration. It is imperative to design a new forestry policy to assure the conservation of one of the most unique biodiversity hotspots worldwide.
Facing unprecedented drying of the Central Andes? Chile contains most of the temperate forest in South America and more than half of the temperate forest in the southern hemisphere. Chilean temperate forest is considered to be one of the world's biodiversity hotspots. In this study we assessed the rate of land use and land cover LULC change over time, identified the main LULCs replacing native forest, and described how changes have evolved in contrasting physiographical conditions and through different historical phases of the landscape over the last 40 years.
We found substantial differences in temporal and intra-regional patterns of forest loss and LULC change. In the Coastal range, rapid land cover change has taken place since , with an increasing rate of forest loss over time. We detected a similar but less intense pattern in the forests of the Andean range. He located 3 hotspots. The first was the master bedroom and described the woman exactly as my wife had seen her. My friend and my wife had no prior contact. The next location was an upstairs bedroom on the 3rd floor where the servants stayed.
He believed there was a lot of chatter, laughter and story telling between the maids about the family they worked for. The last hot spot was a small room in the basement. There he felt the presence of a young boy who was constantly locked up for bad behaviour. This boy was the second owner of the house.
