Post-mating spermatophore storage strategies in two species of crayfish: implications for broodstock management

Animal, 2018
Female crayfish stores male gametes after mating until the beginning of egg laying and fertilization. The aim of the present study was to investigate the duration of post-mating spermatophore storage as well as the timing and temperature of spawning in ...

Blue plaque review series: Thomas Graham Brown: Before his time. [PDF]

Exp Physiol
Abstract Thomas Graham Brown made a seminal discovery, published in 1911 while he was a Carnegie Fellow in the University of Liverpool laboratory of Nobel Prize winner Charles S. Sherrington. Working in cats, he showed that rhythmic ‘voluntary’ behaviour, such as stepping and, by inference, walking, does not result from a chain of reflex events, but ...

Influence of water regulation and water flow on Noble crayfish (Astacus astacus) catch yield in Ljungan a Northern Swedish River after building of a power plant

, 2010
Free-flowing water is thought to be of importance for reproduction and body growth of noble crayfish (Astacus astacus (Linné)) in the northern edge of its distribution area.A hydroelectric power plant with a bypass tunnel was built in the river Ljungan ...
