Abstract:
... Modelling the potential impacts of future climate on ecosystems provides important information for environmental planning and management. The Holdridge life zones system is a land classification based on simple bioclimatic variables that can be used for evaluating the potential effect of future climates on ecosystems. However, information on future bioclimatic changes in ecoregions of southern Sou ...
... Wetlands provide many important ecosystem functions and services worldwide and are hotspots of biological diversity. However, depressional wetlands are particularly vulnerable to effects of climate change due to the significant role that precipitation and surface runoff play in shaping their hydrology. In the Southern Great Plains of North America, climate projections predict more extreme storm ev ...

Abstract:
... AIM: Species shift their ranges as a consequence of climate change, hence modifying the structure of local assemblages. This may have important consequences for ecosystem functioning in the case of ecosystem engineers such as earthworms, especially when community restructuring leads to an alteration of their functional diversity. Here, we aimed to model the potential modification of the functional ...
... The 1972 World Heritage Convention (WHC) and 1994 Global Strategy aim to preserve the outstanding universal value of internationally important cultural and natural sites within a “representative, balanced and credible” network of highly-protected areas. Increasing human pressures and shortfalls in representation have been documented across the World Heritage network, particularly in terrestrial an ...
... The mountain ecosystems are fragile because of topography and extreme climatic conditions. The Hindu-Kush Himalayan (HKH) region is a biodiversity-rich ecosystem and highly vulnerable to climate change and anthropogenic activities among the mountains. In HKH, the climate change impacts on ecologically specialist species are already evident, but generalist species are not much studied. One such gen ...

Abstract:
... AIM: The Appalachian forests ecoregion in eastern North America supports a diverse and highly endemic temperate biota, which is potentially threatened by rapid climate change. We investigated possible outlooks for biodiversity in this biologically important ecoregion under future climate change. LOCATION: Appalachian forests ecoregion, USA. METHODS: We estimated distributional shifts for 258 fores ...

Abstract:
... Paleoclimate reconstructions for the western US show spatial variability in the timing, duration, and magnitude of climate changes within the Medieval Climate Anomaly (MCA, ca. 900–1350 CE) and Little Ice Age (LIA, ca. 1350–1850 CE), indicating that additional data are needed to more completely characterize late-Holocene climate change in the region. Here, we use dendrochronology to investigate ho ...

Abstract:
... The assessment of climate impact on marine communities dwelling deeper than the well‐studied shelf seas has been hampered by the lack of long‐term data. For a long time, the prevailing expectation has been that thermal stability in deep ocean layers will delay ecosystem responses to warming. Few observational studies have challenged this view and indicated that deep organisms can respond exception ...
... AIM: Araucaria moist forests are particularly vulnerable to climate change due to their strict climatic requirements and patchy distribution. Therefore, identifying areas where these forests are expected to lose or retain climatically suitable space (i.e., climate change refugia) is urgently required. Here, we modeled the current and future climatic suitability for Araucaria moist forests aiming: ...

... Arctic freshwaters are facing multiple environmental pressures, including rapid climate change and increasing land___use activities. Freshwater plankton assemblages are expected to reflect the effects of these stressors through shifts in species distributions and changes to biodiversity. These changes may occur rapidly due to the short generation times and high dispersal capabilities of both phyto ...

Abstract:
... Understanding the interplay between ecological and population genetic processes through space and time is a central goal of landscape genetics. However, most studies that place diversification dynamics in an ecological context have focused on vertebrates, leaving a significant gap in our understanding of the effects of ecosystem change on community composition and demography of invertebrates. In t ...

Abstract:
... Understanding sources of variation in animal thermal limits is critical to forecasting ecological responses to climate change. Here, we estimated upper and lower thermal limits, and their capacity to respond to thermal acclimation, in several species and populations of diving beetles (Dytiscidae) from diverse geographic regions representative of variable climate within South Africa. We also consid ...
... Here, we present results from a study conducted in two major shrimp fishing grounds in the Northeastern Brazil Marine Ecoregion (NBME) that determined reproductive dynamics of the penaeid shrimps Xiphopenaeus kroyeri and Penaeus schmitti. We aimed to verify if the current closed season is appropriate and untangle the environmental drivers that control their dynamics. The periods of recruitment and ...

Abstract:
... The ecosystem based adaption (EbA) approach mobilizes ecosystem products and services to reduce people’s vulnerability and improve adaptation to climate change. The approach is being tested and promoted globally including Nepal. However, there are limited studies on why EbA faces challenges of mainstreaming and wider upscaling in developing countries' policies and practices. Based on an empirical ...

Abstract:
... The Greater Everglades Ecosystem is a globally important ecoregion, home to 68 threatened or endangered species and the largest designated wilderness area in the Eastern United States. Anthropogenic manipulations of the natural hydrology have led to widespread degradation of this ecosystem and monitored population declines across multiple taxa. Simultaneous introductions of hundreds of non-native ...

Abstract:
... The importance of monitoring shrublands to detect and understand changes through time is increasingly recognized as critical to management. This research focuses on ecological change observed over 10 yr of field observation at 126 plots and over 35 yr of the Landsat archive in a shrubland ecosystem. Field data consisting of the fractional cover of shrubs, sagebrush, herbs, litter, and bare ground ...

Abstract:
... Urban, peri urban and patch forests play a critical role in climate change mitigation through increased carbon storage and for that, it is imperative to assess the species response in an eco-region to recommend a potentially higher carbon sequestering species. In urban settings, green spaces, in particular, trees play a vital role in preserving biodiversity, reducing the impact of urban heat islan ...
... Habitat fragmentation and its effects on the persistence of populations and species are of major concern to conservation biology. Penstemon coriaceus is a rare and endemic species from the Mexican Central Plateau and adjacent foothills of the Sierra Madre Occidental and Sierra Madre Oriental, which belongs to the Chihuahuan Desert ecoregion. This is the first study that integrates population genet ...

Abstract:
... Conversion of land cover is one of the main causes of global environmental change and identifying the regions where sustained trends of land change are occurring provides useful information for land and resources management. For all ecoregions in Mexico, we analyzed land use changes over 14 years (2001–2014) using MODIS images (250m) and identified regions that had significant gains or loss of woo ...

Abstract:
... There is long-standing ecological and socioeconomic interest in what controls the diversity and productivity of ecosystems. That focus has intensified with shifting environmental conditions associated with accelerating climate change. The U.S. Northeast Shelf (NES) is a well-studied continental shelf marine ecosystem that is among the more rapidly warming marine systems worldwide. Furthermore, man ...
