Abstract Inbreeding depression results in a decrease in the average phenotypic values of affected traits. It has been traditionally estimated from pedigree‐based inbreeding coefficients. However, with the development of single‐nucleotide polymorphism arrays, novel methods were developed for calculating the inbreeding coefficient, and consequently ...

Longevity in South African Afrikaner cows as assessed through survival analysis
Abstract The Afrikaner breed of cattle is indigenous to South Africa and, due to their hardiness, was once the most popular breed amongst South African farmers, although in recent years their numbers have decreased. The goal of this study was to assess factors affecting length of productive life, defined as the interval between production of the first ...

The role of historical biogeography in shaping colour morph diversity in the common wall lizard
Abstract The maintenance of polymorphisms often depends on multiple selective forces, but less is known on the role of stochastic or historical processes in maintaining variation. The common wall lizard (Podarcis muralis) is a colour polymorphic species in which local colour morph frequencies are thought to be modulated by natural and sexual selection.

Understanding the distribution of organisms along elevational gradients across a range of latitudes and geographical areas is important to be able to inform conservation measures. Using Orthoptera in the Pyrenees as a study system, we found a decline in species richness with increasing elevation, but no evidence for Rapoport's elevational rule ...

Alliance et lien social en Languedoc (XVIIe-XVIIIe s.)
El model familiar que predominava al Baix Llanguedoc en el segle xviii presenta moltes similituds amb aquells que existien als Pirineus, al Massís Central o a l’Alta Provença: es basava en la devolució de la majoria dels béns a un únic hereu universal ...
