Reintroduction of North Island robins to Paengaroa Scenic Reserve : factors limiting survival, nest success, and population viability in a mainland restoration area : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Ecology at Massey University [PDF]

open access: yes, 2001
Forty North Island robins (Petroica australis longipes) were reintroduced to Paengaroa Scenic Reserve in March 1999. I monitored the survival and breeding success of this population for two years post-release.

Fitness costs associated with building and maintaining the burying beetle's carrion nest [PDF]

open access: yes, 2016
It is well-known that features of animal nest architecture can be explained by fitness benefits gained by the offspring housed within. Here we focus on the little-tested suggestion that the fitness costs associated with building and maintaining a nest ...

Effect of supplementary feeding on reproductive success of hihi (stitchbird, Notiomystis cincta) at a mature forest reintroduction site [PDF]

open access: yes, 2017
Supplementary feeding has proven to be a successful conservation tool for many species, including New Zealand’s hihi (stitchbird, Notiomystis cincta). Previous research has shown supplementary feeding to substantially increase hihi reproductive success ...

Using eggshell membranes as a DNA source for population genetic research [PDF]

open access: yes, 2009
In the context of population genetic research, a faster and less invasive method of DNA sampling would allow large-scale assessments of genetic diversity and genetic differentiation with the help of volunteer observers.

Impact of Nest-Site Selection on Nest Success and Nest Temperature in Natural and Disturbed Habitats

open access: yesEcology, 2002
Nest-site selection behavior is a maternal effect that contributes to offspring survival and variation in offspring phenotypes that are subject to natural selection. We investigated nest-site selection and its consequences in the snapping turtle, Chelydra ser- pentina, in northwestern Illinois.

Nest predation in an urbanizing landscape: the role of exotic shrubs [PDF]

open access: yes, 2004
Nest predation is considered a primary force shaping avian communities, and landscape-scale features (e.g., amount of fragmentation) are generally recognized as factors mediating nest predation.

A genetic assessment of parentage in the blackspot sergeant damselfish, Abudefduf sordidus (Pisces: Pomacentridae) [PDF]

open access: yes, 2019
Microsatellite markers were used to investigate the reproductive behavior of the damselfish Abudefduf sordidus at Johnston Atoll, Central Pacific Ocean.

Effect of an ectoparasite on lay date, nest-site choice, desertion, and hatching success in the great tit (Pants major) [PDF]

open access: yes, 2017
Ectoparasites are common in most bird species, but experimental evidence of their effects on life-history traits is scarce. We investigated experimentally the effects of the hematophagous hen flea (Ceratophyllus gallinae) on timing of reproduction, nest ...

Vegetation structure linked to nest site selection and nest survival of northern bobwhite

open access: yesWildlife Society Bulletin
Nesting success of northern bobwhites (Colinus virginianus) is related to the interaction of habitat and predators because vegetation can act as a buffer to obscure visual and olfactory nest cues.
