Nest-site selection in a fish species with paternal care

Nest Site Selection by Sea Turtles

Isotocin regulates paternal care in a monogamous cichlid fish.

While the survival value of paternal care is well understood, little is known about its physiological basis. Here we investigate the neuroendocrine contributions to paternal care in the monogamous cichlid, Amatitlania nigrofasciata. We first explored the dynamic range of paternal care in three experimental groups: biparental males (control fathers housed with their mate), single fathers (mate r...

Lack of costs associated with nest-related behaviors in an arachnid with exclusive paternal care

Nest-related behaviors may benefi t males by increasing off spring survival and their attractiveness to females, but may also limit males ’ foraging activity, increase their metabolic expenses, and expose them to increased mortality during nest attendance. Although intensively studied among birds and ectothermic vertebrates, the costs of nest-related behaviors in arthropods remain poorly explor...

Nest site selection by Holarctic waterfowl: a multi-level review

Because of birds’ mobility, behaviour and many species’ migratory nature, they select repeatedly and spatially among habitats and have been central figures in studies of avian breeding habitat selection during the 20th and 21st centuries. The scientific literature on habitat use by breeding waterfowl has origins dating back to the writings of Charles Darwin in The Voyage of the Beagle, wherein ...

Nest Predation and Nest-site Selection of a Western Population of the Hermit

Audubon’s Hermit Thrushes (Cutharus guttatus auduboni) in central Arizona have a low nesting success (7 to 20%) due almost exclusively to nest predation. We examine the sites chosen for nesting and compare them to nonuse sites randomly selected within the vegetation types associated with nests. Hermit Thrush nest sites differ from nonuse sites primarily in that nest sites have more small (lto 3...
