PREDATOR VIGILANCE AND GROUP SIZE IN MAMMALS AND BIRDS: A CRITICAL REVIEW OF THE EMPIRICAL EVIDENCE
- M. Elgar
- Biology, Medicine
- Biological reviews of the Cambridge Philosophical…
- 1 February 1989
One commonly cited benefit to animals that forage in groups is an increase in the probability of detecting a predator, and a decrease in the time spent in predator detection. A mathematical model… Expand
The functional significance of silk decorations of orb‐web spiders: a critical review of the empirical evidence
- M. Herberstein, C. L. Craig, J. Coddington, M. Elgar
- Biology, Medicine
- Biological reviews of the Cambridge Philosophical…
- 1 November 2000
A number of taxonomically diverse species of araneoid spiders adorn their orb‐webs with conspicuous silk structures, called decorations or stabilimenta. The function of these decorations remains… Expand
9 – Sperm Competition and Sexual Selection in Spiders and Other Arachnids
- M. Elgar
- Biology
- 1998
The chapter focuses on Polyandry, which sets the stage for sperm competition, and may provide female spiders with both material and genetic benefits. The material benefits include a reduction in the… Expand
The evolution of pheromone diversity.

- PloS one
- 27 December 2006
We examined the publication records of a cohort of 168 life scientists in the field of ecology and evolutionary biology to assess gender differences in research performance. Clear discrepancies in… Expand
SEXUAL CANNIBALISM, SIZE DIMORPHISM, AND COURTSHIP BEHAVIOR IN ORB‐WEAVING SPIDERS (ARANEIDAE)
- M. Elgar
- Biology, Medicine
- Evolution; international journal of organic…
- 1 March 1991
The variation in sexual size dimorphism in dioecious organisms, both within and between taxonomic groups, is thought to arise from differential sexual selection and natural selection acting… Expand
Foraging strategies and feeding regimes: Web and decoration investment in Argiope keyserlingi Karsch (Araneae: Araneidae)
- M. Herberstein, C. L. Craig, M. Elgar
- Biology
- 2000
The principal foraging cost for web-building spiders is the amount of silk invested in their webs. Spiders in the genus Argiope additionally decorate their orb webs with conspicuous UVwhite silk… Expand

Sleep in mammals
Abstract Quiet sleep (QS) was correlated with a different set of constitutional variables from those associated with active sleep (AS), in a sample of 69 species of mammals. The time spent in quiet… Expand
Sexual Cannibalism in Orb-Weaving Spiders: An Economic Model
Sexual cannibalism in orb-weaving spiders commonly takes place before copulation, even among virgin females. This behavior is curious because, although the female may obtain a nutritious meal, she… Expand
Evolutionary Significance of Sexual Cannibalism
- M. Elgar, J. Schneider
- Biology
- 2004
Publisher Summary “Sexual cannibalism” refers to females killing and consuming their male partner at some stage during courtship and mating. Sexual cannibalism can occur before or during mating,… Expand
