Hybridization may drive rare taxa to extinction through genetic swamping, where the rare
form is replaced by hybrids, or by demographic swamping, where population growth rates …

The unit of adaptation is usually thought to be a gene or set of interacting genes, rather than
the whole genome, and this may be true of species differentiation. Defining species on the …

▪ Abstract The α-proteobacterium Wolbachia pipientis is a very common cytoplasmic
symbiont of insects, crustaceans, mites, and filarial nematodes. To enhance its transmission …

Throughout the natural world, organisms have responded to predators, inadequate
resources, or inclement conditions by forming ongoing mutually beneficial partnerships--or …

Teleost fish, which roughly make up half of the extant vertebrate species, exhibit an amazing
level of biodiversity affecting their morphology, ecology and behaviour as well as many other …

New insights in the speciation process and the nature of “species” that accumulated in the
past decade demand adjustments of the species concept. The standing of some of the most …

Understanding the phenotypic and molecular mechanisms that contribute to genetic
diversity between and within species is fundamental in studying the evolution of species. In …

Wolbachia are cytoplasmically inherited bacteria that cause a number of reproductive
alterations in insects, including cytoplasmic incompatibility,, an incompatibility between …
