Population genetics of Polyphemus pediculus, (Cladocera: Polyphemidae)

Spontaneous and Evoked Eye Movements in Polyphemus Pediculus (cladocera: Crustacea): a Case of Open-loop Tracking?

1. Polyphemus eye movements were recorded in both pitching and yawing planes, both in a static visual environment and with a sinusoidally moving stimulus. 2. Spontaneous eye movements (average amplitude 1-7°) had different properties in the two planes, with trembling movements predominating in the pitching plane. A contour-sharpening function is proposed for these movements. 3. An attempt to an...

Evolutionary Genetics Theoretical Population Genetics

Evolutionary genetics studies the patterns and mechanisms of genetic changes underlying evolutionary change. Because biological diversity at all levels (including population, species, and ecosystem diversity) has a genetic basis and is a result of evolution, evolutionary genetics provides insight into the ultimate mechanisms creating biodiversity. Evolutionary genetics utilizes empirical tools ...

Population genetics

Population genetics is the study of genetic variability within a population and of the forces that act upon it. As well as being of central importance to our understanding of evolution from prehistoric to modern times, it now also affects our everyday lives — whether considering human genetic disease, how to avoid the extinction of rare species or the merits of ‘DNA fingerprinting’ in forensic ...
