This work presents LOSITAN, a selection detection workbench based on a well evaluated Fst-outlier detection method that greatly facilitates correct approximation of model parameters, provides data import and export functions, iterative contour smoothing and generation of graphics in a easy to use graphical user interface.

It is shown that many advances come from the fields of forensics, human health and domestic animal health science, and it is suggested that molecular ecologists explore literature from these fields, to continually increase the power and role of noninvasive genetics in molecular ecology and conservation genetics.

Previously undescribed genetic evidence is presented in contrast with this view based on mtDNA sequences from five Italian aurochsen dated between 7,000 and 17,000 years B.P. and >1,000 modern cattle from 51 breeds to suggest the European cattle may represent a more variable and valuable genetic resource than previously realized.
Chicken domestication: an updated perspective based on mitochondrial genomes
The assessment of chicken mtDNA data facilitated the understanding about the Austronesian settlement in the Pacific and revealed new complexities of history in chicken domestication because in the phylogeny lineages from the red junglefowl were mingled with those of the domestic chickens.
African Origins of the Domestic Donkey
The history and origins of the donkey are particularly interesting because, together with the horse, the donkey ( Equus asinus ) has been used for the transportation of people, possessions, and…

These findings resolve the long-standing issue of the role of the Nubian wild ass in the domestication of the donkey, but raise new questions regarding the second ancestor for the donkey.
Hidden Consequences of Living in a Wormy World: Nematode‐Induced Immune Suppression Facilitates Tuberculosis Invasion in African Buffalo

Using a disease dynamic model parameterized with empirical data, it is found that nematode‐induced immune suppression can facilitate the invasion of bovine TB in buffalo, and TB failed to invade the system, illustrating the critical role nematodes may play in disease establishment.
Zebu cattle are an exclusive legacy of the South Asia neolithic.
Evidence from 844 zebu mitochondrial DNA sequences surveyed from 19 Asiatic countries comprising 8 regional groups is reported, which identify 2 distinct mitochondrial haplogroups, termed I1 and I2, which support the Indus Valley as the most likely center of origin for the I1 haplogroup and a primary center of zebe domestication.
Gene-culture coevolution between cattle milk protein genes and human lactase genes
Substantial geographic coincidence between high diversity in cattle milk genes, locations of the European Neolithic cattle farming sites and present-day lactose tolerance in Europeans suggests a gene-culture coevolution between cattle and humans.
