| reliable effective number of breeders/adult census size ratios in seasonal-breeding species: opportunity for integrative demographic inferences based on capture-mark-recapture data and multilocus genotypes. | the ratio of the effective number of breeders (nb) to the adult census size (na), nb/na, approximates the departure from the standard capacity of a population to maintain genetic diversity in one reproductive season. this information is relevant for assessing population status, understanding evolutionary processes operating at local scales, and unraveling how life-history traits affect these processes. however, our knowledge on nb/na ratios in nature is limited because estimation of both paramet ... | 2017 | 29238556 |
| effects of sample size and full sibs on genetic diversity characterization: a case study of three syntopic iberian pond-breeding amphibians. | accurate characterization of genetic diversity is essential for understanding population demography, predicting future trends and implementing efficient conservation policies. for that purpose, molecular markers are routinely developed for nonmodel species, but key questions regarding sampling design, such as calculation of minimum sample sizes or the effect of relatives in the sample, are often neglected. we used accumulation curves and sibship analyses to explore how these 2 factors affect mar ... | 2017 | 28444211 |
| high pathogen prevalence in an amphibian and reptile assemblage at a site with risk factors for dispersal in galicia, spain. | ranaviruses are agents of disease, mortality and population declines in ectothermic vertebrates and emergences have been repeatedly linked to human activities. ranaviruses in the common midwife toad ranavirus lineage are emerging in europe. they are known to be severe multi-host pathogens of amphibians and can also cause disease in reptiles. recurrent outbreaks of ranavirus disease and mortality affecting three species have occurred at a small reservoir in north-west spain but no data were avail ... | 2020 | 32730306 |
| comparative assessment of range-wide patterns of genetic diversity and structure with snps and microsatellites: a case study with iberian amphibians. | reduced representation genome sequencing has popularized the application of single nucleotide polymorphisms (snps) to address evolutionary and conservation questions in nonmodel organisms. patterns of genetic structure and diversity based on snps often diverge from those obtained with microsatellites to different degrees, but few studies have explicitly compared their performance under similar sampling regimes in a shared analytical framework. we compared range-wide patterns of genetic structure ... | 2020 | 33072264 |
