- Multimodal communication in crayfish: sex recognition during mate search by male Austropotamobius pallipes. // Canadian Journal of Zoology;Nov2002, Vol. 80 Issue 11, p2041
Investigates the role of multiple signals in sex recognition in the crayfish Austropotamobius pallipes. Analysis of the main channels used by males during mate search; Tracking of the behavioral responses of males; Responses of both males and females to chemical and visual stimuli.
- Inbreeding depression and mating systems in two species of Linanthus (Polemoniaceae). Goodwillie, Carol // Heredity;Mar2000, Vol. 84 Issue 3, p283
Theory predicts that, at equilibrium, the magnitude of inbreeding depression caused by recessive alleles should decrease as the level of self-fertilization increases, facilitating the evolution of even higher selfing rates. Data are presented on mating systems and inbreeding depression in...
- Male-Produced Aggregation Pheromone of the Cerambycid Beetle Rosalia funebris. Ann Ray; Jocelyn Millar; J. McElfresh; Ian Swift; James Barbour; Lawrence Hanks // Journal of Chemical Ecology;Jan2009, Vol. 35 Issue 1, p96
Abstract��We report the identification, synthesis, and field bioassays of a volatile, male-produced aggregation pheromone of a long-horned beetle, the banded alder borer, Rosalia funebris Mots. Headspace collections from males contained a major male-specific compound, (Z)-3-decenyl...
- pheromone:. Schlegel, Rolf H. J. // Encyclopedic Dictionary of Plant Breeding & Related Subjects;2003, p316
A definition of the term "pheromone" is presented. It refers to a chemical exchanged between members of the same animal species that effects behavior. The affected behavior includes sex attractants, alarm substances, aggregation-promotion substances
- Spotted Sandpiper. Kaufman, Kenn // Birder's World;Aug2008, Vol. 22 Issue 4, p44
The article offers information on how to identify Spotted Sandpiper. The bird is relatively short-legged, long-tailed and straight-billed. It has a pale brown face, darker eye-line and crown and manifests a pale brown patch at the side of the chest. It is noted that the spots on Spotted...
- On the Use of Virtual Animals with Artificial Fear in Virtual Environments. Delgado-Mata, Carlos; Martinez, Jesus Ibanez; Bee, Simon; Ruiz-Rodarte, Rocio; Aylett, Ruth // New Generation Computing;2007, Vol. 25 Issue 2, p145
Virtual environments are often static and empty of life. One way of combating this problem is by populating the environment with autonomous agents that behave in a life-like manner. This paper discusses the incorporation of animals into such environments and the definition of appropriate...
- Sex on eight legs. Coghlan, Andy // New Scientist;01/06/2001, Vol. 169 Issue 2272, p6
Reports on the discovery that female wandering spiders use pheromones to lure mates. How male and female spiders find one another by causing vibrations with their appendages; Possible use of the pheromone to trap nuisance spiders or attract pest-consuming spiders to farmland.
- ELUSIVE AND PASSIONATE. // Wellness Options;2005, Issue 20, p16
Reveals that some odorless molecules, referred as pheromones, are sensed by the vomeronasal organ (VNO) and are released and perceived as chemical communications between members of a species. Information on the discovery of the first pheromone; Controversies in regards to the chemical identity...
- Absence of social facilitation of courtship in the wolf spider, Schizocosa ocreata (Hentz) (Araneae: Lycosidae). Roberts, J. Andrew; Galbraith, Emily; Milliser, Jenai; Taylor, Phillip W.; Uetz, George W.; Oliveira, R. // Acta Ethologica;Dec2006, Vol. 9 Issue 2, p71
Males of many animal species are reproductively limited by the difficulty and time costs of finding mates. Males of such species should be selected to take advantage of any cues that might reveal the location of prospective mates. Cues to female location are not restricted to those produced by...
