Nesting ecology of an ice‐associated seabird, Kittlitz's murrelet, at the northern edge of its range
Wildlife Society Bulletin, EarlyView.We studied the Kittlitz's murrelet, an ice‐associated seabird of conservation concern, at the northern edge of its range. Over a 2‐year period, we estimated nest density and success at 2 sites, captured and telemetered nesting murrelets, and tested the use of a thermal camera to improve nest detection.

Wildlife Society Bulletin, EarlyView.We studied how conservation grazing influenced vegetation composition and structure and greater prairie‐chicken nest survival in northwestern Minnesota. We observed effects of grazing on vegetation in the year of grazing, but these changes dissipated by August of the post‐grazing year.

Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Animal coloration serves a variety of visually related functions in nature (e.g. mate choice, aposematism and camouflage) but the pigments in integumentary tissues such as skin, scales and feathers may also serve functions unrelated to the visual environment (e.g ...

Animal Conservation, EarlyView.We show that the introduction of artificial substrates, in this case, dredged materials to act as nesting substrate for ground‐nesting birds, reduced the effectiveness of egg camouflage for Kentish plovers compared to natural substrates. However, nesting success was not impacted, likely because the community of nest predators was diverse and used a ...
