Anisotropic patterned population synchrony in climatic gradients indicates nonlinear climatic forcing.
Although climatic forcing has been suspected to be the most common cause of spatial population synchrony owing to the Moran effect, it has proved difficult to disentangle the impact of climate from other possible causes of synchrony based on population survey data. Nonlinear population responses to climatic variation may be a part of this difficulty, but they can also provide an opportunity to ...
متن کاملVegetation‐infiltration relationships across climatic and soil type gradients
[1] The enhancement of infiltration capacity in the presence of vegetation is well documented in arid ecosystems where it can significantly impact the water balance and vegetation spatial organization. To begin progress toward developing a theory of vegetation‐infiltration interactions across a wide spectrum of climate regimes, three key questions are addressed: (1) Does vegetation also enhance...
متن کاملBiogenic gradients in algal density affect the emergent properties of spatially self-organized mussel beds.
Theoretical models highlight that spatially self-organized patterns can have important emergent effects on the functioning of ecosystems, for instance by increasing productivity and affecting the vulnerability to catastrophic shifts. However, most theoretical studies presume idealized homogeneous conditions, which are rarely met in real ecosystems. Using self-organized mussel beds as a case stu...
متن کاملEffects of Global Warming on Predatory Bugs Supported by Data Across Geographic and Seasonal Climatic Gradients
Global warming may affect species abundance and distribution, as well as temperature-dependent morphometric traits. In this study, we first used historical data to document changes in Orius (Heteroptera: Anthocoridae) species assemblage and individual morphometric traits over the past seven decades in Israel. We then tested whether these changes could have been temperature driven by searching f...
متن کاملThe Brazilian freshwater wetscape: Changes in tree community diversity and composition on climatic and geographic gradients
Wetlands harbor an important compliment of regional plant diversity, but in many regions data on wetland diversity and composition is still lacking, thus hindering our understanding of the processes that control it. While patterns of broad-scale terrestrial diversity and composition typically correlate with contemporary climate it is not clear to what extent patterns in wetlands are complimenta...
