Sex-chromosome differentiation and 'sex races' in the common frog (Rana temporaria).
Sex-chromosome differentiation was recently shown to vary among common frog populations in Fennoscandia, suggesting a trend of increased differentiation with latitude. By rearing families from two contrasted populations (respectively, from northern and southern Sweden), we show this disparity to stem from differences in sex-determination mechanisms rather than in XY-recombination patterns. Offs...
متن کاملMicrosatellite marker data suggest sex-biased dispersal in the common frog Rana temporaria.
Despite being important models in ecological, evolutionary and conservation biology research, very little is known about the dispersal in anuran amphibians, and juvenile dispersal in particular. Using microsatellite data, we assessed signatures of sex-biased migration in the common frog (Rana temporaria) in Scandinavia. Significant heterozygosity deficiency (FIS) and lower assignment value (mAI...
متن کاملA first-generation microsatellite linkage map of the ruff
A linkage map of the ruff (Philomachus pugnax) genome was constructed based on segregation analysis of 58 microsatellite loci from 381 captive-bred individuals spanning fourteen breeding years and comprising 64 families. Twenty-eight of the markers were resolved into seven linkage groups and five single marker loci, homologous to known chicken (Gallus gallus) and zebra finch (Taeniopygia guttat...
متن کاملBiospectroscopy reveals the effect of varying water quality on tadpole tissues of the common frog (Rana temporaria).
Amphibians are undergoing large population declines in many regions around the world. As environmental pollution from both agricultural and urban sources has been implicated in such declines, there is a need for a biomonitoring approach to study potential impacts on this vulnerable class of organism. This study assessed the use of infrared (IR) spectroscopy as a tool to detect changes in severa...
متن کاملThe influence of water and light upon the pigmentary system in the common frog Rana temporaria.
Many factors, both internal and external, influence the chromatic changes of coldblooded vertebrates, and of these, three external variables are recognized as significant—light, heat and moisture. The frog can change its colour, from brown or black through intermediate tints to pale lemon, by changing the contraction and expansion of three types of chromatophores—the epidermal and dermal melano...
