“…Others are associated with specific vegetation species or formations. Required habitat species may fail to migrate, such as Jack pine in the well documented case of Kirtland's warbler (Botkin et al 1991). Annual migrants depend on the availability of specific habitats for 'refueling' stops on their journeys, require satisfactory conditions for fat build-up and moult prior to setting off, and may migrate in synchrony with the availability of transient food sources.…”

ABSTRACT. Climate change represents a significant threat to global biodiversity and ecosystem integrity. The UN Framework Convention on Climate Change (UNFCCC), which has been ratified by 118 nations and came into force in 1994, has amongst its aims the protection of ecosystems. This paper reviews the relevant text in the Convention and gives an overview of scientific efforts to provide policymakers wlth the necessary information on ecosystem impacts. The sensitivity of different types of ecosystem to climatic change is discussed and the concepts of ecological limits and thresholds are addressed and examples given. The paper concludes there is a need for a better understanding of the impacts of climate change on ecosystem resilience in order to maintain biological diversity and respond to the needs of policymakers in implementing the UNFCCC. Recommendations are made for increased research effort, including increased resolution of climate models, better predictive capacity at a regional level for within-and between-year rainfall patterns, seasonality and extreme events. Collaborative monitoring programs, including long-term ecological research along climate gradients, are proposed for 4 biomes: coastal wetlands, montane ecosystems, coral reefs and Arctic ecosystems.

“…Global environmental changes may lead to dramatic alterations in floral and faunal composition, species dominance, and the structure, function, and distribution of ecosystems, and via these processes may cause species extinctions (Peters, ; Busby, ; Main, ; Cohn, ; Fajer, ; Greenwood & Boardman, ; Mansergh & Bennett, ; Botkin et al , ; Dennis & Shreeve, ; Woodward & Rochefort, ). Enhanced greenhouse effect climate change has presented major problems for the survival of species (Jackson et al , ; Loarie et al , ; Dawson et al , ; Bellard et al , ).…”

1. Global environmental change can dramatically alter the composition of floral and faunal communities, and elucidating the mechanisms underlying this process is important for predicting its outcomes. Studies on global climate change have mostly focused on statistical summaries within wide spatial and temporal scales; less attention has been paid to variability in microclimates at narrower spatial and temporal scales. 2. The microclimate is the suite of climatic conditions measured in a local area. Environmental variables at the microclimatic scale can be critical for the ecology of organisms inhabiting each area. The effect of spatial and temporal changes in the microclimate on the ecology of carabid beetle communities in three sites on Mount Odaesan, Korea was examined. 3. Carabid beetle communities and quantified site‐specific environmental factors from measurements of air temperature, air humidity, light intensity and soil temperature over 5 years (2010–2015) were surveyed. 4. It was found that microclimatic variables and the patterns of temporal changes in carabid beetle communities differed between the three sites within the single mountain system. Microclimatic variables influencing temporal changes in beetle communities also differed between the sites. Therefore, it is suggested that variation in local microclimates affects spatial and temporal variation in carabid beetle communities at a local scale. 5. The present results demonstrate the importance of regular surveys of communities at local scales. Such surveys are expected to reveal an additional fraction of variation in communities and underlying processes that have been overlooked in studies of global community patterns and change.

“…Using various correlational and mechanistic approaches, analyses of potential vegetation redistribution under doubled CO, climate indicate possible movement of major life zones on the order of hundreds of kilometres horizontally or up to 1000 m vertically (Emanuel et al 1985, Solomon 1986, Davis 1989, Neilson et al 1989, Prentice 1990). Mechanistic approaches have been more lim-ited in spatial extent, being generally applied at a point in space or over a network of points (Solomon 1986, Pastor and Post 1988, Botkin et al 1991.

Accurate prediction of the ecological impacts of climatic change is a pressing challenge to the science of ecology. The current state of the art for broad-scale estimates of change in biomes and ecotones between biomes is limited to equilibrium estimates of ecological change under some future equilibrium climate. Uncertainties in these estimates abound, ranging from uncertainties in future climate scenarios to uncertainties in our ecological models and finally to uncertainties in modelling the feedbacks between the climate and the biosphere. Ecologists and policymakers need to go beyond equilibrium estimates of biosphere change to transient responses of the biosphere as the climate changes. Ecotones between biomes have been suggested as sensitive areas of change that could be effectively modelled and monitored for future change. Ecotones are also important in influencing local and regional biodiversity patterns and ecological flows. The ecological processes that could affect change at ecotones and within biomes are discussed; they include internal ecosystem processes, such as competition, and external abiotic processes, most notably drought and related disturbances. Drought followed by infestations and fire appears to be the most likely process that could mediate ecological change under a rapidly changing climate. The impacts would be apparent all across biomes, not just at ecotones. However, specific predictions about the dynamics of ecotones can be made qualitatively, based on a theory of patch scaling and diversity in relation to abiotic stressors. Under current conditions, the size of homogeneous patches is expected to be small at ecotones, but to enlarge with distance from the ecotone. Directional climatic change should promote a coalescence of patches on one side of the ecotone and increased fragmentation on the other side. Ecotones should begin to blur as viewed from a satellite only to re-form at some later date in a new location. This view is in contrast to the notion that ecotones would retain sharp distinction and simply move across the landscape. These changes are presented as hypotheses based on theory and should be testable in a mechanistic modeling framework that is only now being developed.
