Investigations of opsin evolution outside of vertebrate systems have long been focused on insect visual pigments while other groups have received little attention. Furthermore, few studies have...
Applications of phylogenetics to issues in freshwater crayfish biology (2005)
reshwater crayfish have served as model organisms for over 125 years in scientific research, from areas such as neurobiology and vision research to conservation biology and evolution. Recently,...

Identification of species in natural populations has recently received increased attention with a number of investigators proposing rigorous methods for species delimitation. Morphologically...
The Impact of Species Concept on Biodiversity Studies (2004)
Species are defined using a variety of different operational techniques. While discussion of the various methodologies has previously been restricted mostly to taxonomists, the demarcation of species...
