Mitochondrial DNA regionalism and historical demography in the extant populations of Chirocephalus kerkyrensis (Branchiopoda: Anostraca). [PDF]
PLoS ONE, 2012 BackgroundMediterranean temporary water bodies are important reservoirs of biodiversity and host a unique assemblage of diapausing aquatic invertebrates. These environments are currently vanishing because of increasing human pressure.

Long distance dispersal of zooplankton endemic to isolated mountaintops--an example of an ecological process operating on an evolutionary time scale. [PDF]
PLoS ONE, 2011 Recent findings suggest a convergence of time scales between ecological and evolutionary processes which is usually explained in terms of rapid micro evolution resulting in evolution on ecological time scales.

Mating Patterns and Speciation in the Fairy Shrimp Genus Streptocephalus [PDF]
Evolution, 1979 According to a recent paradigm of the speciation process presented by Ayala (1975), geographic speciation often occurs in two stages. In the first stage isolated populations accumulate genetic differences which may reduce the genetic compatibility between populations. In the second stage the isolated populations regain sympatry. If hybrids have reduced

Aquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.ABSTRACT Growth and haematological parameters are used in aquaculture as indicators of the health of cultivated fish in response to changes in diet and the physicochemical conditions of the water. In this study, the physiological status of Totoaba macdonaldi was evaluated based on growth, haematological parameters and blood chemistry in response to two

Ecology Letters, Volume 29, Issue 3, March 2026.We integrate laboratory assays and GPS tracking to examine consistent risk‐taking behaviour in Fan‐tailed Ravens (Corvus rhipidurus) inhabiting Israel's Dead Sea coastline. Individual risk profiles were consistent across lab and field contexts, with risk‐prone birds remaining near tourist sites and risk‐averse birds ranging farther into natural ...
