(Oxford University Press, 1991)Simple game theory models predict that individuals should not signal reliable information about he likelihood of attacking their opponents. We investigated the relationship between the likelihood of attacking a conspecific ...
-
(Oxford University Press, 1993)One of the foraging decisions facing parasitoids is whether to accept (superparasitize) or reject hosts that have already been parasitized. An important distinction is whether the host has been parasitized by the female ...
-
(Oxford University Press, 1991)We present a dynamic model of food allocation to starling nestlings. Based on the premise that current reproductive activities may have detrimental effects on future breeding episodes, the model is elaborated around the ...
-
(Oxford University Press, 1990)In an anadromous population of threespine sticklebacks (Gasterosteus aculeatus), only a minority of 1-year-old (1 +) males enter the spawning grounds to reproduce. The majority of males on the spawning grounds are 2-year-old ...
-
(Oxford University Press, 1993)Social groups of capybaras, Hydrochaeris hydrochaeris, averaging 10 adults contained a mean of 3.6 adult males. Of 2911 interactions observed within social groups of capybaras, 34% were among adult males, and these were ...
-
(Oxford University Press, 1993)The calls produced by male katydids serve to attract females and repel rivals. Males generally exhibit overt aggressive responses to conspecifics that call within their territories, and intermale spacing is maintained by ...
-
(Oxford University Press, 1994)The presence of alloparents in cooperatively breeding groups may enhance the reproductive performance of the breeding pair but tests of this hypothesis in mammalian cooperative breeders have typically examined short periods ...
-
(Oxford University Press, 1992)Male burying beetles, Nicrophorus vespilloides Herbst (Coleoptera: Silphidae), use two alternative mate-finding tactics: males can (1) search for carcasses that serve as oviposition sites or (2) attract mates via pheromone ...
-
(Oxford University Press, 1993)Male eastern gray squirrels (Sciurus carolinensis) congregate around and pursue a female on her single day of estrus. The tactics of uniquely marked adult males were monitored during winter mating bouts from 1986 to 1990 ...
-
(Oxford University Press, 1993)Male red-winged blackbirds (Agelaius phoeniceus) provisioned 50%(118/235) of available broods over an 8-year period. In most cases, each male provisioned only the oldest brood on his territory, but in 21 cases, the male ...
-
(Oxford University Press, 1994)Many species of animals face the continual problem of balancing the trade-off between reducing predation risks and maintaining or increasing their reproductive fitness. The terms of the trade-off are often asymmetric: each ...
-
(Oxford University Press, 1995)The characteristics of young with respect to basic development factors greatly affect whether one parent is able to raise the young on its own and, hence, the flexibility of mating systems. In most bird species, the young ...

-
(Oxford University Press, 1993)Although hoarding has been studied intensively for many decades, few studies have attempted to measure its actual fitness consequences. To fill this gap, we used ptilochronology, the growth of replacement feathers as a ...
-
(Oxford University Press, 1993)
-
(Oxford University Press, 1993)Because pocket gophers have the high energetic cost of excavating burrows and an inability to detect distant food items through the soil, I hypothesized that individuals within established burrow systems would use ...
-
(Oxford University Press, 1995)Home range size, overlap between home ranges, movement patterns and social behavior in two generations of female field voles were examined by radio tracking unrelated individuals in enclosed areas. In addition, potential ...
