Small and large wetland fragments are equally suited breeding sites for a ground-nesting passerine

Documenting relationships between small mammals, ground-nesting passerine birds, and grazing systems on private rangelands in the Nebraska sandhills

Introduction Biologists lack a great deal of information about wildlife in the Nebraska Sandhills, especially on private rangelands. For example, there is little knowledge about the small mammals of the area and their role in the ecosystem in which they live. Because only three percent of Nebraska is public land (Schneider et. al 2005), private land management is, by default, critical to the bi...

Breeding sows better suited to group housing

Housing of pregnant sows is currently being revolutionised around the world. Group housing enhances opportunities for improved sow health and welfare through enabling exercise and social interactions. However, because it enables social interactions, group housing can also be detrimental to welfare and production, particularly if sow aggression occurs. Detrimental effects of adverse interactions...

Shifts in Bacterial Communities of Eggshells and Antimicrobial Activities in Eggs during Incubation in a Ground-Nesting Passerine

Microbial invasion of egg contents is a cause of embryonic death. To counter infection risks, the embryo is protected physically by the eggshell and chemically by antimicrobial proteins. If microbial pressure drives embryo mortality, then females may have evolved, through natural selection, to adapt their immune investment into eggs. Although frequently hypothesized, this match between immune a...
