Postinsemination Associations Between Males and Females in Insects: The Mate-Guarding Hypothesis
- J. Alcock
- 1994
Biology
A major goal of evolutionary biologists is to identify the evolved function of particular traits. In developing hypotheses about the possible adaptive value of a characteristic of interest,…
Inclusive fitness theory and eusociality
- P. Abbot, J. Abe, Andrew G. Zink
- 24 March 2011
Biology, Philosophy
Nature
It is argued that inclusive fitness theory has been of little value in explained the natural world, and that it has led to negligible progress in explaining the evolution of eusociality, but these arguments are based upon a misunderstanding of evolutionary theory and a misrepresentation of the empirical literature.
Female mimicry and resource defense polygyny by males of a tropical rove beetle, Leistotrophus versicolor (Coleoptera : Staphylinidae)
- A. Forsyth, J. Alcock
- 1 May 1990
Biology
Behavioral Ecology and Sociobiology
Adults of the staphylinid beetle Leistotrophus versicolor Grav aggregate at vertebrate dung and carrion where males and females forage for adult Diptera, and female mimicry is a conditional tactic of mature males.
Selenium biofortification of high-yielding winter wheat (Triticum aestivum L.) by liquid or granular Se fertilisation
- M. Broadley, J. Alcock, F. Zhao
- 2009
Chemistry
Plant and Soil
Selenium (Se) is an essential trace element for humans and livestock. In the UK, human Se intake and status has declined since the 1980s. This is primarily due to the increased use of wheat (Triticum…
THE EVOLUTION OF THE USE OF TOOLS BY FEEDING ANIMALS
- J. Alcock
- 1 September 1972
Biology
Evolution; international journal of organic…
Examination of cases of tool-using behavior by animals feeding under natural conditions and to discuss the origin, transmission, and subsequent evolution of this behavior to make a modest case for the opposite position.
The ecology and evolution of male reproductive behaviour in the bees and wasps
- J. Alcock, E. M. Barrows, F. Zalom
- 1 December 1978
Biology
Of special interest in multiple-mating by females, which may be an evolutionary response to the costs of attempting to resist copulation in certain situations, are the ecological and evolutionary bases of these differences that are explored in this paper.
Male Mating Strategies in the Bee Centris pallida Fox (Anthophoridae: Hymenoptera)
- J. Alcock, C. Jones, S. Buchmann
- 1 January 1977
Biology
American Naturalist
The possibility that females which provision a number of small cells (thus producing several small males) may be as fit as or fitter than females that divide their investment into relatively few packets and produce a few large males is examined.
SLEEPING AGGREGATIONS OF THE BEE IDIOMELISSODES DUPLOCINCTA (COCKERELL) (HYMENOPTERA : ANTHOPHORINI) AND THEIR POSSIBLE FUNCTION
- J. Alcock
- 1998
Biology
Male bees in sleeping aggregations apparently gain anti-predator benefits largely through the dilution effect, suggesting that odor cues applied by sleeping bees (or some other special properties of the favored stems) attract male bees coming to roost sites.
The relation between male body size, fighting, and mating success in Dawson's burrowing bee, Amegilla dawsoni (Apidae, Apinae, Anthophorini)
- J. Alcock
- 1 August 1996
Biology
A large male mating advantage applies across years and among populations, making it potentially advantageous for females of Dawson's burrowing bees to produce large, superior fighting sons about the same size as their daughters.
