Abstract Animals must balance various costs and benefits when deciding to breed. The of breeding at different times have received much attention, but most studies been limited investigating short‐term season‐to‐season fitness effects. However, early, versus late, in a season may influence lifetime over many years, trading off complex ways across the breeder’s lifespan. In this study, we examined complete life histories 867 female tree swallows ( Tachycineta bicolor ) Ithaca, New York,...
Social foragers may be regarded as being engaged in a producer-scrounger game which they can search for food independently or join others who have discovered food. Research on the has focused mainly different factors influencing its ESS solution, but very little is known about actual mechanisms that shape players' decisions. Recent work shown early experience affect foraging tendencies young house sparrows, and nutmeg mannikins learning involved reaching ESS. Here we show direct manipulation...
Abstract Conditions during early life can have dramatic effects on adult characteristics and fitness. However, we still know little about the mechanisms that mediate these relationships. Telomere shortening is one possibility. Telomeres are long sequences of DNA protect ends chromosomes. They shorten naturally throughout an individual's life, individuals with short telomeres tend to poorer health reduced survival. Given this connection between telomere length (TL) fitness, natural selection...
Faunal lists are important tools in ecology, biogeography, and conservation planning. Such can identify gaps our knowledge of the distribution taxonomy regional faunas, highlight issues needing further study. We present an up to date list all land vertebrates occurring Israel. 786 species, which 551 birds, 130 mammals, 97 reptiles eight amphibians. Of these 369 species breed Israel (including reintroductions), 199 (mostly birds) regular visitors 182 accidental. Fourteen other invasive, 22...
Wiliwili (Erythrina sandwicensis), an endemic Hawaiian dry forest tree species, is threatened by invasive gall-forming wasp (Quadrastichus erythrinae) first detected in Hawai'i 2005. Eurytoma erythrinae, a predator of Q. erythrinae from Tanzania, was selected as biological control agent and released at sites throughout the Islands. To assess effectiveness this biocontrol release, we measured extent damage attributable to wasps 124 E. sandwicensis trees Waikoloa Village Dry Forest Recovery...
The “good-genes” hypothesis to explain female extra-pair mating states that females benefit from this behavior by acquiring better genes for their offspring. Despite extensive research, results are mixed, and the predictions of good-genes have been met in fewer than half published papers. One possible explanation lack consensus is benefits copulation context-dependent. Here we use chick size, probability fledging, telomeres, protective caps chromosomes, as markers individual quality....
