Thus, this proposal provides opportunities to explore spatial structure of beetle populations, understanding how local and regional factors interact to drive patterns of coexistence and species diversity of lentic alpine water bodies, and how these processes can change with global warming. Under future conditions, however, the metacommunity is likely to suffer a spatial homogenization linked to extinction of local populations and the rise of generalists that dampen the role of cold hardiness in community assembly. Under present‐day conditions, environmental filtering (as a consequence of cold hardiness) and interspecific competition allows the existence of local communities with a very distinctive species richness and composition. Specifically, we aim to disentangle the spatial distribution of cohabiting water beetles in alpine ponds of Sierra Nevada (south Spain), their metapopulation dynamics and coexistence mechanisms, as well as to test whether climate change can cause shifts in metacommunity structure. In this proposal, we aim to understand the potential effects of climate change on macroinvertebrate metacommunity structuring of Mediterranean alpine ponds.
It hosts a system of alpine ponds of glacial origin that harbour relatively simplified biological communities because of their environmental homogeneity, but contain highly specific, cold-adapted species assemblages. The Sierra Nevada mountain range in Spain is the southernmost high mountain in Europe and represents one of the areas with the highest values of biodiversity and endemicity of the Iberian Peninsula. However, the role of niche‐ and dispersal‐based dynamics on aquatic organisms of alpine lentic waterbodies is still largely unknown. Alpine lakes and ponds are considered sentinels of environmental change and represent hence an ideal system model to study the effects of global warming on metacommunities. In high-altitude freshwaters, global warming will likely affect biodiversity (e.g., species extinctions, changes in the composition of assemblages) and water resources.
