Abstract:
... Agonistic interactions between obligate avian brood parasites and their hosts can lead to the coevolution at any stage of the nesting cycle, yet adaptations and counter-adaptations at the fledgling stage are poorly known. Young of the host-specialist screaming cowbird (Molothrus rufoaxillaris) closely resemble those of its greyish baywing (Agelaioides badius) host in appearance and begging calls. ...

acoustics; aggression; animal communication; humans; males; plasticity; social behavior; sociobiology; songbirds; wildlife
Abstract:
... Anthropogenic noise may disrupt signals used to mediate aggressive interactions, leading to more physical aggression between opponents. One solution to this problem is to switch signaling effort to a less noisy modality (e.g., the visual modality). In the present study, we investigate aggressive behaviors and signaling in urban and rural male European robins (Erithacus rubecula) in response to sim ...

Anura; antipredatory behavior; escape behavior; flight; frogs; intraspecific variation; males; phenotype; predation; risk; sociobiology
Abstract:
... Escape efficiency typically relies on locomotor performance, which depends on morphology. Moreover, flight initiation distance (FID, the distance from an approaching predator at which a prey starts flight) is behaviourally adjusted to minimize the costs of escape. When conspecifics with distinct heritable traits are subjected to differential predator pressure, specialized antipredator strategies m ...

Abstract:
... Obligate brood parasites rely upon unrelated hosts to provide parental care for their offspring. Specialist brood parasites use visual and vocal mimicry of host offspring to induce host parents to care for the parasite offspring. Generalist brood parasites, however, use different tactics to obtain host parental care. Here, we examine how brown-headed cowbirds (Molothrus ater) restructure host red- ...

Abstract:
... Viviparity has evolved from oviparity approximately 142 times among vertebrates. Different theories have been proposed to explain the evolution of each of its traits in the different taxa. None, however, is applicable to all the viviparous vertebrates, since the derived ecological advantages such as controlling incubating temperature or protecting eggs against predation differ amongst clades.

Polygyny, the presence of multiple reproductive queens in a single colony, and polyandry, multiple mating by females, both increase the genetic variability in colonies of eusocial organisms, resulting in potential reproductive conflicts. The co-occurrence of polygyny and polyandry in a single species is rare ...

Abstract:
... Life-history theory predicts trade-offs between investment in current versus future reproduction. However, many studies find no or even positive correlations among these traits. The absence of the trade-off may result from resource availability, as it influences resource allocation to different traits. In addition, since large amounts of resources require additional effort in processing, resource ...

Abstract:
... The adaptive significance of flocking in birds has been long debated. In particular, the formation of flocks is thought to increase foraging efficiency and reduce predation pressure. Such benefits can compensate for the costs of flocking including increased competition for resources. The evolution of flocking among species is thus likely shaped by ecological factors related to food abundance and d ...

The onset of spring migratory behavior in birds is thought to be controlled by a rigid endogenous schedule as a result of selection to time migration with environmental conditions on breeding grounds. Recent field studies, however, have revealed flexibility in spring departure schedules and suggest a role for environmental factors such as weather and food availability. Here, we investigated the ro ...

Abstract:
... The role of sexual selection in mediating levels of sexual conflict has been demonstrated in many experimental evolution studies on Drosophila spp. where competition among males for mating was the target of selection. Sexual selection has also been shown to affect the evolution of life-histories. However, the influence of divergent life-histories on reproductive strategies and, therefore, sexual s ...

Abstract:
... High reproductive performance is the key attribute of male fitness, especially due to the high reproductive skew among the males of most animal species. Males of long-lived iteroparous species have opportunities to improve upon their previous reproductive attempts with increasing age. We collected individual-specific reproductive behaviour and age data on a cyprinid fish, the asp (Leuciscus aspius ...

Abstract:
... Most large felids are classified as solitary species, with only lions (Panthera leo) and cheetahs (Acinonyx jubatus) exhibiting social, collaborative behaviours. Herein, we present evidence of the formation of male coalitions by jaguars (Panthera onca), based on data from five studies conducted with camera trapping, GPS telemetry, and direct observations in the Venezuelan Llanos and Brazilian Pant ...
