Ibis, EarlyView.Hatching failure represents a significant and growing barrier to reproductive success in threatened birds and yet is often poorly understood. Populations of the Eurasian Curlew Numenius arquata in the United Kingdom and Republic of Ireland have experienced significant declines over recent decades, and low breeding productivity is a major barrier to ...

Insect Conservation and Diversity, EarlyView.Bees are integral pollinators commonly found in and supported by urban green spaces; however, their eco‐evolutionary response to urbanisation varies interspecifically. While several studies have explored the population and landscape genetics of bees in response to urbanisation, few have examined solitary or specialist species which may be more ...

Insect Conservation and Diversity, EarlyView.Mottled Duskywing (Erynnis martialis) populations had moderate levels of genetic diversity at microsatellites with expected heterozygosity ranging from 0.43 to 0.58, and populations more than 10 km apart were differentiated from one another. Weak patterns of isolation by distance and low effective population sizes suggest that all but the largest ...

Evaluating Selection Strategies Based on Inbreeding Load via Simulation
Journal of Animal Breeding and Genetics, EarlyView.ABSTRACT Inbreeding load is the fraction of the mutation load that is due to recessive action of mutations. This load is only expressed in individual's inbred offspring. As such, inbreeding load contributes to genetic heterogeneity among individuals and can thus be used as a criterion of selection.

Journal of Animal Breeding and Genetics, EarlyView.ABSTRACT Inbreeding increases the likelihood of deleterious recessive alleles becoming homozygous and consequently affecting economically important traits. Runs of homozygosity (ROH), the continuous homozygous segments of the genome and the higher than expected homozygosity (HOM) are genomic indicators of inbreeding, quantified as FROH and FHOM ...

In pursuit for impeccable veracity [PDF]
I study the institution of avoiding to hire one’s school own PhD graduates for assistant professorships. I argue that this institution is necessary to create better incentives for researchers to incorporate new information in studies, facilitating the ...

Journal of Animal Breeding and Genetics, EarlyView.ABSTRACT Ewe's functional longevity impacts flock profitability by reducing annual ewe replacement costs and increasing ewe outputs over the production cycle. In this context, the main objective of this study was to estimate variance components and genetic parameters of five ewe longevity indicators in South African Merino sheep.

Journal of Animal Breeding and Genetics, EarlyView.ABSTRACT Resilience is the capacity of an animal to be minimally affected by disturbances or to rapidly return to its pre‐disturbance state. To the best of our knowledge, no previous study has investigated resilience in the giant freshwater prawn (GFP, Macrobrachium rosenbergii).
