A Free-Ranging, Feral Mare Equus Caballus Affords Similar Maternal Care To Her Genetic And Adopted Offspring, Cassandra M.V. Nuñez, James S. Adelman, Daniel I. Rubenstein
A Free-Ranging, Feral Mare Equus Caballus Affords Similar Maternal Care To Her Genetic And Adopted Offspring, Cassandra M.V. Nuñez, James S. Adelman, Daniel I. Rubenstein

Adoption of nongenetic offspring occurs in a variety of species but is rare in equids. We report a case of adoption by a free-ranging, feral mare Equus caballus and compare the maternal care received by her genetic offspring (born 1995) to that of her adopted offspring (born 1996) for the first 30 weeks of development. We compare five measures of care: (1) total time spent suckling, (2) mare aggression during suckling, (3) number of mare-terminated suckling bouts, (4) contact maintenance, and (5) mare-foal distance. For most behaviors, we detected no difference in the mare’s treatment of the two foals; however, …

Host individuals and populations often vary in their responses to infection, with direct consequences for pathogen spread and evolution. While considerable work has focused on the mechanisms underlying differences in resistance—the ability to kill pathogens— we know little about the mechanisms underlying tolerance— the ability to minimize fitness losses per unit pathogen. Here, we examine patterns and mechanisms of tolerance between two populations of house finches (Haemorhous [formerly Carpodacus] mexicanus) with different histories with the bacterial pathogen Mycoplasma gallisepticum (MG). After infection in a common environment, we assessed two metrics of pathology, mass loss and eye lesion severity, as proxies …

A system and method capable of hydrolyzing lactose, where the system includes a support formed from a functionalized hydrophobic polymer that is covalently linked to a hydrophilic molecule covalently that is, in turn, covalently linked to an enzyme such as lactose. The method includes the steps of functionalizing a hydrophobic polymer support, covalently linking a hydrophilic molecule to said functionalized polymer support, and covalently linking an enzyme such as lactase to said hydrophilic molecule. The system and method generally relate to the field of food science and engineering and, more particularly to dairy-based food products and their production including solutions …
