ABSTRACT A key to understanding life's great diversity is discerning how competing
organisms divide limiting resources to coexist in diverse communities. While temporal …

The current range of European vipers is mostly parapatric but local‐scale allopatric
distribution is common and few cases of sympatry are known. In the High Course of Ebro …

maintain niche separation between all species. Temporal partitioning has received less …

This thesis aimed to assess the ecological factors that determine the long-term persistence
and viability of animal populations across severely fragmented landscapes. The lowland …

Quantifying diet is essential for understanding the functional role of species with regard to
energy processing, transfer, and storage within ecosystems. Recently, variance structure in …

Invaders affect native species across multiple trophic levels, influencing the structure and
