Social Assemblages And Mating Relationships In Prairie Dogs: A Dna Fingerprint Analysis, Steven E. Travis, Con Slobodchikoff, Paul Kefan
Social Assemblages And Mating Relationships In Prairie Dogs: A Dna Fingerprint Analysis, Steven E. Travis, Con Slobodchikoff, Paul Kefan
Reproductive Behavior Collection
Mating system characterizations have been hindered by difficulties in accurately assigning parentage to offspring. We investigated the relationship between social assemblages and mating relationships in a territorial harem polygynous mammal, the Gunnison's prairie dog, using a combination of behavioral and molecular analyses. We demonstrate multiple paternity and an extraordinarily high incidence of extraterritorial fertilizations (i.e., 61% of all progeny), in combination with the existence of female kin groups. On this basis, we conclude that social assemblages alone provide a poor description of the Gunnison's prairie dog mating system, and suggest several potential reasons for the maintenance of territoriality in this …
Habitat And Courtship Behavior Of The Wolf Spider Schizocosa Retrorsa (Banks) (Araneae, Lycosidae), Eileen Hebets, Gail E. Stratton, Gary Miller
Habitat And Courtship Behavior Of The Wolf Spider Schizocosa Retrorsa (Banks) (Araneae, Lycosidae), Eileen Hebets, Gail E. Stratton, Gary Miller
Eileen Hebets Publications
The habitat and courtship behavior of the wolf spider Schizocosa retrorsa (Banks 1911) were studied and are described here for the first time. The range of S. retrorsa was extended to include the lower peninsula of Michigan. This species is locally abundant in highly exposed habitats of sand or pine litter. Male courtship consists of chemoexploration, palpal drumming, an extended leg tap, and a "push-up" display. Female displays include a double leg arch, approaches, and orientations toward the male.

Visual Search For Natural Grains In Pigeons (Columba Livia) : Search Images And Selective Attention, Cynthia M. Langley, Donald A. Riley, Alan B. Bond, Namni Goel
Papers in Behavior in Biological Sciences
The experiments reported here were designed to test the suggestion of many researchers that selective attention to visual features of a prey can account for search-image effects. In 3 experiments pigeons ate wheat and vetch grains presented on multicolored and gray gravel trays. In Experiment 1 search-image effects were evident when grains were cryptic but not when they were conspicuous. Experiment 2 demonstrated that search images can be activated when the grains encountered are either cryptic or conspicuous but that search images affect search performance only when the grains are cryptic. Experiment 3 demonstrated that search images are short-term in …
Pattern And Duration Of Copulation In Wolf Spiders (Araneae, Lycosidae), Gail E. Stratton, Eileen Hebets, Patricia R. Miller, Gary L. Miller
Pattern And Duration Of Copulation In Wolf Spiders (Araneae, Lycosidae), Gail E. Stratton, Eileen Hebets, Patricia R. Miller, Gary L. Miller
Eileen Hebets Publications
The temporal patterns of insertion of male palps, expansion of the hematodocha and duration of copulation are reported for 10 species of Schizocosa Chamberlin 1904, three species of Rabidosa Roewer 1955, one species of Gladicosa Brady 1986, one species of Hogna Simon 1885, two species of Isohogna Roewer 1960, one species of Trochosa C.L. Koch 1848, one species of Geolycosa Montgomery 1904, two species of Arctosn C.L. Koch 1848, three species of Alopecosa Simon 1885 and six species of Pardosa C.L. Koch 1847. In all species of Schizocosa examined so far, males showed a pattern composed of a series of …

Predicting Cognitive Capacity From Natural History: Examples From Four Species Of Corvids, Russell P. Balda, Alan Kamil, Peter A. Bednekoff
Papers in Behavior in Biological Sciences
Birds have been studied for centuries because they are numerous, conspicuous, and aesthetically pleasing to humans. Despite their overall regard for birds, historically, many ornithologists have considered birds as instinct-driven organisms of little intellectual capacity. For example, the ornithological textbook of choice from the 1960s states the following view of avian intelligence:
Flight has proven to be an enormously successful evolutionary venture, but one that has cost birds dearly in mental development. In effect, problems merely by flying away from them. … As a consequence, much [avian] behavior is, by mammalian standards, fragmentary, stereotyped, and at times amazingly stupid. (Welty, …
