Data from: Lack of habitat segregation and no interspecific territoriality in three syntopic cryptic species of the golden-spectacled warblers Phylloscopus (Seicercus) burkii complex

Alexey Opaev & Yulia Kolesnikova
It is widely accepted that exploitative competition prevents the coexistence of any two or more closely-related species unless differences exists in their ecological niches and resource use. In sibling bird species, exploitative competition is reduced mainly by spatial segregation of competing species. Spatial segregation can be achieved in two basic ways: by using different habitats or microhabitats that each species is predominately exploiting, or by interspecific territoriality. To our knowledge, either habitat segregation or interspecific...

Data from: Trophic consistency of supraspecific taxa in belowground invertebrate communities: comparison across lineages and taxonomic ranks

Anton M. Potapov, Stefan Scheu & Alexei V. Tiunov
1. Animals that have similar morphological traits are expected to share similar ecological niches. This statement applies to individual animals within a species and thus species often serve as the functional units in ecological studies. Species are further grouped into higher-ranked taxonomic units based on their morphological similarity and thus are also expected to be ecologically similar. On the other hand, theory predicts that strong competition between closely related species may result in differentiation of...

Innate anti-predator behavior can promote infection in fish even in the absence of predators

Victor Mikheev, Anna Pasternak, Andrey Morozov & Jouni Taskinen
Natural enemies - predators and parasites - largely shape the dynamics of ecosystems. It is known that anti-predator and anti-parasite defense can be mutually conflicting, however consequences of this trade-off for the regulation of infection burden in animals are still poorly understood. We hypothesize that even in the absence of cues from predators, innate anti-predator behavior (“ghost of predation past”) interferes with defense against parasites and can enhance the infection risk. As a case study,...

Evidence for divergence between sympatric stone charr and Dolly Varden along unique environmental gradients in Kamchatka.

Nikolai Melnik, Grigorii Markevich, Eric Taylor, Evgeny Esin & Aleksey Loktyushkin
Here we describe the biological and ecological differences between partially anadromous Dolly Varden and riverine stone charr distributed in the Kamchatka River middle course. Endemic stone charr, being the ambush predator, is defined by the accelerated growth and prolonged lifespan, robust body and large mouth, as well as specific marble colouration since an early age. The significant restriction in gene flow between the stone charr and benthos-eating Dolly Varden was supported by an allelic distribution...
