Field experiments of success-breeds-success dynamics [PDF]

Proceedings of the National Academy of Sciences, 2014
Significance Social scientists have long debated why similar individuals often experience drastically different degrees of success. Some scholars have suggested such inequality merely reflects hard-to-observe personal differences in ability.

Successful breeding predicts divorce in plovers [PDF]

Scientific Reports, 2020
AbstractWhen individuals breed more than once, parents are faced with the choice of whether to re-mate with their old partner or divorce and select a new mate. Evolutionary theory predicts that, following successful reproduction with a given partner, that partner should be retained for future reproduction. However, recent work in a polygamous bird, has

A comparison of the breeding biology of White-throated Kingfisher Halcyon smyrnensis Linnaeus, 1758 in plains and hilly areas of Bangladesh

Journal of Threatened Taxa, 2022
The breeding biology of White-throated Kingfisher Halcyon smyrnensis was studied in plains and hilly areas from September 2008 to August 2011. Four villages under Savar upazilla were selected for plains, and Chittagong University Campus, Chattagram for ...

Migratory Dates, Breeding Phenology, and Reproductive Success of European Turtle Doves between Lowlands and Highest Breeding Habitats in North Africa

International Journal of Zoology, 2020
The migratory time, breeding chronology, and reproductive success of the European turtle doves (Streptopelia turtur) were studied in Midelt as a high-altitude breeding habitat and Beni Mellal as a low-altitude breeding site from 2015 to 2018 in Morocco ...

Factors driving territory size and breeding success in a threatened migratory songbird, the Canada Warbler

Avian Conservation and Ecology, 2016
Successful conservation of migratory birds demands we understand how habitat factors on the breeding grounds influences breeding success. Multiple factors are known to directly influence breeding success in territorial songbirds.

Reproductive Consequences of Nest Site Use in Fork-tailed Storm-Petrels in the Aleutian Islands, Alaska: Potential Lasting Effects of an Introduced Predator

Avian Conservation and Ecology, 2010
We examined the reproductive consequences of differential nest site use in Fork-tailed Storm-Petrels (Oceanodroma furcata) in the Aleutian Islands, Alaska, where birds on islands where foxes were introduced nest in rocky substrate rather than in typical ...

Breeding site attendance and breeding success in Phyllomedusa trinitatis (Anura: Phyllomedusidae)

Phyllomedusa: Journal of Herpetology, 2021
Using a natural marker, we documented breeding site attendance patterns by males and females of the Trinidad Leaf Frog, Phyllomedusa trinitatis. We followed attendance at a cluster of three isolated ponds over 53 and 56 consecutive nights in 2016 and ...

Using self-organizing maps to investigate environmental factors regulating colony size and breeding success of the White Stork (Ciconia ciconia) [PDF]

, 2013
We studied variations in the size of breeding colonies and in breeding performance of White Storks Ciconia ciconia in 2006–2008 in north-east Algeria. Each colony site was characterized using 12 environmental variables describing the physical environment,

The population status, breeding success and diet of Subantarctic Skuas two decades after the feral cat eradication on Marion Island [PDF]

, 2013
Prey availability is often the driver behind predator population trends, diet and breeding success. Changes in predator abundance and breeding success represent numerical responses to changes in prey abundance, whereas dietary shifts can be classified as
