Sexual harassment in live-bearing fishes (Poeciliidae): comparing courting and noncourting species
TLDR
The time females spent feeding was found to significantly decline with increasing male mating activity, but there was no support for the idea that females would spend more time feeding in the presence of courting males compared with noncourting ones.
Biotic interchange between the Indian subcontinent and mainland Asia through time
TLDR
A novel method to investigate the temporal dynamics of biotic interchange based on a phylogeographical meta-analysis by calculating the maximal number of observed dispersal events per million years given the temporal uncertainty of the underlying time-calibrated phylogenies is presented.
Male mate choice and sperm allocation in a sexual/asexual mating complex of Poecilia (Poeciliidae, Teleostei)
TLDR
Amazon mollies (Poecilia formosa) require sperm to trigger embryogenesis, but the males (e.g. Poecilia mexicana) do not contribute genes, so the importance of male choice in this system is underscored.
A phylogeographic framework for the conservation of Saharan and Arabian Dorcas gazelles (Artiodactyla: Bovidae)
TLDR
A phylogenetic analyses, statistical parsimony network analysis and inferred colonization patterns shed doubt on the validity of various described subspecies of G. dorcas, infer a steep population decline that started approximately 25,000 years before present and is still ongoing, which coincides with human activities in Saharan Africa.
Phylogenetic analysis of mitochondrial DNA sequences reveals polyphyly in the goitred gazelle (Gazella subgutturosa)
TLDR
A phylogenetic framework is provided, based on the analysis of mtDNA sequences of a number of individuals collected from the wild and captivity throughout the species’ natural range, which revealed a polyphyly within the presumed species of G. subgutturosa resulting in two distinct clades.

TLDR
Strong molecular divergence over short distances as well as phenotypic and quantitative genetic divergence across habitats in directions classic to fish ecomorphology suggest that divergent selection is structuring phenotypesic variation in this system.
Parallel evolution of cox genes in H2S-tolerant fish as key adaptation to a toxic environment.
TLDR
It is demonstrated that even closely related lineages follow both parallel and disparate molecular evolutionary paths to adaptation in response to the same selection pressure.
