Electroreception, the capacity to detect external underwater electric fields with specialised
receptors, is a phylogenetically widespread sensory modality in fishes and amphibians. In …

The bony-tongue fishes, Osteoglossomorpha, have been the focus of a great deal of
morphological, systematic, and evolutionary study, due in part to their basal position among …

Throughout their lives animals must complete many tasks, including finding food, avoiding
predators, attracting mates, and navigating through a complex and dynamic environment …

Even before the publication of Darwin's Origin of Species, the perception of evolutionary
change has been a tree-like pattern of diversification-with divergent branches spreading …

Species delimitation directly impacts on global biosecurity. It is a critical element in the
decisions made by national governments in regard to the flow of trade and to the biosecurity …

Natural selection arising from resource competition and environmental heterogeneity can
drive adaptive radiation. Ecological opportunity facilitates this process, resulting in rapid …

The question we address in this article is how hybridization in the recent past can be
detected in recently evolved species. Such species may not have evolved genetic …

Although mitochondrial DNA markers have several properties that make them suitable for
phylogeographic studies, they are not free of difficulties. Phylogeographic inferences within …

Fish populations are increasingly being subjected to anthropogenic changes to their
sensory environments. The impact of these changes on inter-and intra-specific …

Pleistocene climatic fluctuations (PCF) are frequently highlighted as important evolutionary
engines that triggered cycles of biome expansion and contraction. Although there is ample …
