1. Does ecology and life history predict parental cooperation in birds? A comparative analysis

Author:

body size; chicks; data collection; diet; females; invertebrates; life history; males; nests; phylogeny; progeny; sociobiology
Abstract:
... In animals, species differ remarkably in parental care strategies. For instance, male-only care is prevalent in teleost fishes, while biparental care predominates in birds and female-only care is widespread in mammals. Understanding the origin and maintenance of diversified parental care systems is a key challenge in evolutionary ecology. It has been suggested that ecological factors and life-hist ...

Drosophila melanogaster; antagonism; body size; courtship; directed evolution; fecundity; females; life history; males; mortality; sexual selection; sociobiology
Abstract:
... Detrimental effect of males on female, often termed mate harm, is a hallmark of sexual conflict. Allowed to evolve unchecked, mate harming traits are predicted to bring down average fitness of a population, unless mitigated by the evolution of resistance in females. In addition, life history may also modulate sexual conflict, but the mechanism is not clearly understood. Here we investigated the ev ...

Abstract:
... The evolution of obligate kleptoparasitism, the theft of food, has led to remarkable innovations, including physical weapons and chemical signals that can evolve into chemical weapons. Stingless bees in the genus Lestrimelitta are excellent examples of this phenomenon because they are obligate kleptoparasites that no longer collect floral resources and instead steal brood resources from other bees ...

body size; breeding season; burrows; females; males; monogamy; seasonal variation; shrimp; sociobiology; territoriality
Abstract:
... Size-assortative pairing is common across a wide range of taxa. In many cases, both sexes would benefit from pairing with a mate larger than themselves. As males and females cannot simultaneously be larger than their pair mate, size differences within pairs reflect which sex is able to obtain this benefit. Snapping shrimp can be found in pairs year-round, and both males and females would benefit f ...

Traits associated with male dominance status should thus be correlated with reproductive success, but, with the exception of research on some primates, studies with both behavioral data to determine dominance hierarchies and a p ...

Consequently, there can be a direct relationship between song metrics and lifetime reproductive success. While singing is held to be energetically costly, quantitative studies in mammals are lacking. ...

Abstract:
... The ability to win fights is expected to be influenced by the rearing and nutritional conditions experienced by individuals.

Abstract:
... Size-assortative mating is a pattern of non-random pairing among individuals that has been presumed to arise due to the enhanced reproductive success that may accrue from mating with an individual of similar size. Its proximal mechanism may be female choice for similarly sized mates and/or large-male advantage during bouts of direct male-male competition. The hallmark for the occurrence of size-as ...

Abstract:
... Most burrowing shrimps (infraorder Axiidea and Gebiidea) are characterized by solitary habits, which led many of these species to evolve a remarkable sexual dimorphism both in body size and chelipeds because of sexual selection. Given that monogamous species are known to live in heterosexual pairs and exhibit a low degree of sexual dimorphism, it is expected that burrowing shrimps are not monogamo ...

Abstract:
... Defensive strategies, like other life-history traits favored by natural selection, may pose constraints on reproduction. A common anti-predator defense strategy that increases immediate survival is autotomy—the voluntary release of body parts. This type of morphological damage is considered to impose future costs for reproduction and fitness. We tested an alternative hypothesis that animals are ro ...

Western fence lizards (Sceloporus occidentalis) are a key host to western blacklegged ticks (Ixodes pacificus). Males are highly aggressive during the mating season, competing with rivals through displays of color badges, pushups, and other behaviors. We hypothesiz ...

Abstract:
... In polygamy, individuals interact in a non-random manner to shape reproductive networks. However, relative importance of behavior versus individual physical traits (e.g., body size) in determining access to partners and reproductive success varies by species and is poorly understood in small-bodied aquatic species for which direct observations are challenging in the wild. Here, we coupled automate ...

Abstract:
... Parents are expected to strategically partition their limited resources among the current and future progeny in order to maximize their fitness. Since an equal investment in offspring of different reproductive value entails fitness costs, natural selection has promoted the evolution of reliable signals of offspring condition, allowing parents to invest in their progeny accordingly. In birds, mouth ...

Abstract:
... The hypothesis of pace-of-life syndromes (POLS) predicts relationships between traits including life history traits and risk-taking behaviour that can be mediated by the trade-off between current and future reproductive value. However, alternative causal mechanisms may also generate covariance among these traits without trade-offs. We investigated the relationships between survival to the next yea ...

Queens and workers diverge most strongly in the advanced eusocial, or swarm-founding species, where queens do not forage and rarely leave their nests. We asked whether reprod ...

Abstract:
... Status badges, such as crown plumage, mediate intraspecific interactions. The reliability of crown morphology as a status badge in male mountain white-crowned sparrows (Zonotrichia leucophrys oriantha) is uncertain. We examined morphological and physiological correlates of the proportion of crown that was white (“crown-white”) in 178 male mountain white-crowned sparrows during the 2008–2009 breedi ...

Abstract:
... The persistence of behavioral types in situ and the drivers of persistence are central to predicting the ecological effects of intraspecific behavioral variation. We surveyed individual refuge use of mud crabs (Panopeus herbstii), a behavior related to the strength of a trait-mediated trophic cascade in oyster reefs, in the absence and presence of toadfish (Opsanus tau) predation threat. We then r ...

Abstract:
... In the animal kingdom, males typically acquire reproductive access to females through courtship, nuptial gifts, or combat. In many species, small or poor-condition males that are unable to produce an attractive display, proffer an adequate mating gift, or dominate in male–male competition may resort to forced copulation. Forced copulation has been previously demonstrated in the camel cricket Prist ...

Abstract:
... In many mating systems, males adopt alternative reproductive tactics (ARTs) to maximize reproductive success. In fishes, guarding males often invest more energy into courtship, defense, and paternal care, whereas cuckolding males forego such costs and steal fertilizations by releasing their sperm in the nest of a guarding male. These two tactics have been documented in the plainfin midshipman fish ...
