A total of 49 specimens of the rudd, Scardinius erytrophthalmus, were caught in the Łuknajno Lake, in 2005. For each fish, 24 morphometric features of the body and 20 features of the skull were measured. Selected meristi...

Receiver-bias implicated in the nonsexual origin of female mate choice in the pentamorphic fish Poecilia parae Eigenmann, 1894

Receiver-bias hypotheses of signal evolution posit that male sexually selected traits evolve via prior selection for other functions. We found support for the hypothesis that the origin of female choice of mates is a lin...

In vivo treatment of the gill monogenean Pseudorhabdosynochus lantauensis (Monogenea, Diplectanidae) on orange-spotted grouper (Epinephelus coioides) cultured in the Philippines

The gill monogenean Pseudorhabdosynochus lantauensis has been consistently observed on cultured orange spotted-grouper (Epinephelus coioides) fingerlings. The tolerance level of E. coioides to formalin (H2CO solution) an...

Crossing-over between Y chromosomes: another possible source of phenotypic variability in the guppy, Poecilia reticulata Peters

Genetic linkage acting through crossing-over between X and X chromosomes, X and Y chromosomes, and autosomal gene ecombination are the most important sources of color pattern polymorphisms in animals. Variability in male...
