Maternal effects can inflate rate of adaptation to captivity

Genetic adaptation to captivity can occur in a single generation.

Captive breeding programs are widely used for the conservation and restoration of threatened and endangered species. Nevertheless, captive-born individuals frequently have reduced fitness when reintroduced into the wild. The mechanism for these fitness declines has remained elusive, but hypotheses include environmental effects of captive rearing, inbreeding among close relatives, relaxed natura...

Time Clustered Sampling Can Inflate the Inferred Substitution Rate in Foot-And-Mouth Disease Virus Analyses.

With the emergence of analytical software for the inference of viral evolution, a number of studies have focused on estimating important parameters such as the substitution rate and the time to the most recent common ancestor (tMRCA) for rapidly evolving viruses. Coupled with an increasing abundance of sequence data sampled under widely different schemes, an effort to keep results consistent an...

Can Some Animals Adapt Better to Captivity than Others?

There are significant differences among species in their ability to adapt to captivity. Some species breed well in captivity and usually show no apparent signs of poor welfare, while other highly similar species sometimes live only a short time, breed little or not at all and often show abnormal behaviours. Marine mammals provide several examples of these differences. Thus, the life expectancy ...
