The evolution of vocal alarm communication in rodents

Shelley, Erin L.; Blumstein, Daniel T. - In: Behavioral Ecology 16 (2005) 1, pp. 169-177

relative importance of two adaptive hypotheses on the evolution of calling: (1) communicating to predators, which may function … sociality. Phylogenetic tests revealed that the evolution of diurnality preceded the evolution of alarm calling, and that the … in some rodents, may be relatively less important in its evolution.

Reproductive asynchrony and population divergence between two tropical bird populations

Moore, Ignacio T.; Bonier, Frances; Wingfield, John C. - In: Behavioral Ecology 16 (2005) 4, pp. 755-762

High-latitude vertebrates generally breed seasonally and synchronously as the primary environmental cue used to time seasonal processes is photoperiod. Investigations of tropical vertebrates have also documented seasonal reproduction, but it is unclear how synchronous reproduction is, both...

Effects of predation pressure on the cognitive ability of the poeciliid Brachyraphis episcopi

Brown, Culum; Braithwaite, Victoria A. - In: Behavioral Ecology 16 (2005) 2, pp. 482-487

Variable levels of predation pressure are known to have significant impacts on the evolutionary ecology of different populations and can affect life-history traits, behavior, and morphology. To date, no studies have directly investigated the impact of predation pressure on cognitive ability....

Low fertility in humans as the evolutionary outcome of snowballing resource games

Hill, Sarah E.; Reeve, H. Kern - In: Behavioral Ecology 16 (2005) 2, pp. 398-402

For decades, evolutionary biologists and anthropologists have puzzled over the negative relationship that exists between wealth and fertility in humans. Particularly mystifying have been that (1) humans do not appear to translate their reproductive resources into additional offspring, and (2)...

Extrapair paternity and the evolution of bird song

Garamszegi, László Zsolt; Møller, Anders Pape - In: Behavioral Ecology 15 (2004) 3, pp. 508-519

Bird song is usually considered to have evolved in the context of sexual selection. Because extrapair paternity is a major component of sexual selection, mating advantages at the social level for males that produce songs of high quality may be transformed into higher success in extrapair...

On the evolution of polygyny: a theoretical examination of the polygyny threshold model

Ptak, Susan E.; Lachmann, Michael - In: Behavioral Ecology 14 (2003) 2, pp. 201-211

The polygyny threshold model states that if costs incurred are less than the benefits gained from mating polygynously in terms of breeding-situation quality, then polygyny is favored and could evolve. We constructed mathematical models and computer simulations to evaluate this hypothesis. In the...

Mating games: the evolution of human mating transactions

Hill, Sarah E.; Reeve, H. Kern - In: Behavioral Ecology 15 (2004) 5, pp. 748-756

We propose a new, evolutionary, game-theoretic model of conditional human mating strategies that integrates currently disconnected bodies of data into a single mathematically-explicit theory of human mating transactions. The model focuses on the problem of how much resource a male must provide...
