The Role of Local and Regional Processes along the Gradients of Habitat Specialization from a Metacommunity Perspective
… sought to fit data on the entire regional set of species to one of several metacommunity models, implicitly assuming that all species, members of the metacommunity, can be modelled in the same manner (using a single model). However, species differ in their habitat use to the extent that such …

Acoustic Signals of Closely Related Bird Species Differ More in Sympatry Than in Allopatry - But Not If They Are Learned
Closely related species often have similar mating signals because of their shared recent ancestry, which can affect their reproductive isolation and ability to live together when they overlap in range. Similar mating signals can result in costs of co-occurrence (e.g., maladaptive hybridization, …

A Study of Evolutionary Contingency: Characterisation, Mechanisms, and Evidence
… random mutations, recombination, genetic drift, species sorting, and mass extinctions. I conclude that random mutations fail to be a strongsource of contingency as they are often biased towards particular mutational outcomes on account of certain physical dispositions. On the other hand, mass …

The population and community ecology of small freshwater ponds: Assigning process to pattern
… effects) and contemporary processes (e.g., species sorting and interspecific interactions) when studying population and community dynamics. Multiple studies have documented that divergent population and community structures can arise in similar habitats when colonization history differs. For …
