Homoploid hybrid speciation in an extreme habitat.
According to theory, homoploid hybrid speciation, which is hybrid speciation without a change in chromosome number, is facilitated by adaptation to a novel or extreme habitat. Using molecular and ecological data, we found that the alpine-adapted butterflies in the genus Lycaeides are the product of hybrid speciation. The alpine populations possess a mosaic genome derived from both L. melissa an...
متن کاملNotes on Tamagawa Number
Remark 2. It looks like from the definition τ(G) depends on the number field K, so it should be τK(G). If L is a finite extension of K, we have τL(G) = τK(RL/K(G)). Weil showed that in fact the Tamagawa number is independent of Weil restriction, i.e., τL(G) = τK(RL/K(G)) = τK(G). This is proved with details in the paper by Oesterlé ”Nombres de Tamagawa et groupes unipotentes en caractéristique ...
متن کاملHabitat saturation drives thresholds in stream subsidies.
Understanding how abundance regulates the effects of organisms on their ecosystems remains a critical goal of ecology, especially for understanding inter-ecosystem transfers of energy and nutrients. Here we examined how territoriality and nest-digging by anadromous salmon mediate trophic subsidies to stream fishes. Salmon eggs become available for consumption primarily by the digging of salmon ...
متن کاملStream fish, water and habitat quality in a pasture dominated basin, southeastern Brazil.
A fish survey in 35 stream reaches (from 1st to 3rd order) with physicochemical and habitat assessment in the São José dos Dourados system, southeastern Brazil, was conducted. Most of the basin land cover (77.4%) is used for pasture. From the sampled stream reaches, 24 were of good physicochemical quality, 10 of fair quality, and only one of poor quality. A habitat assessment showed that 10 str...
متن کاملExtreme contagion in global habitat clearance.
Habitat clearance remains the major cause of biodiversity loss, with consequences for ecosystem services and for people. In response to this, many global conservation schemes direct funds to regions with high rates of recent habitat destruction, though some also emphasize the conservation of remaining large tracts of intact habitat. If the pattern of habitat clearance is highly contagious, the ...
