PREDATOR VIGILANCE AND GROUP SIZE IN MAMMALS AND BIRDS: A CRITICAL REVIEW OF THE EMPIRICAL EVIDENCE
  • M. Elgar
  • Psychology, Medicine
    Biological reviews of the Cambridge Philosophical…
  • 1 February 1989
TLDR
Most of the studies fail to adequately demonstrate an unambiguous relationship between vigilance behaviour and group size, but many studies reveal interesting features of the relationship between Vigilance and Group size that should provide fruitful avenues for future research.
The functional significance of silk decorations of orb‐web spiders: a critical review of the empirical evidence
TLDR
A phylogenetic analysis of the different decoration patterns suggests that the different types of decorations are as evolutionary labile as the decorations themselves: the analysis shows little homology and numerous convergences and independent gains.
9 – Sperm Competition and Sexual Selection in Spiders and Other Arachnids
TLDR
The chapter focuses on Polyandry, which sets the stage for sperm competition, and may provide female spiders with both material and genetic benefits, and examines precedence patterns involving more than two males.
The evolution of pheromone diversity.
TLDR
Pheromones are chemical signals whose composition varies enormously between species, and studies of phylogeny, genetics and ecological processes are providing new insights into the patterns, mechanisms and drivers of pheromone evolution, and there is a wealth of information now available for analysis.
Gender Differences in Publication Output: Towards an Unbiased Metric of Research Performance
TLDR
It is shown that a recently proposed index designed to rank scientists fairly is in fact strongly biased against female researchers, and advocate a modified index to assess men and women on a more equitable basis.
Foraging strategies and feeding regimes: Web and decoration investment in Argiope keyserlingi Karsch (Araneae: Araneidae)
TLDR
Spiders experiencing low prey encounter rates constructed larger webs and incorporated more silk but fewer web decorations than spiders experiencing high prey encounter Rates, which indicates foraging success by attracting prey to the web.
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
Sperm competition and small size advantage for males of the golden orb‐web spider Nephila edulis
TLDR
Paternity was strongly associated with the duration of copulation, independent of mating order, and small males had a clear mating advantage, they copulated longer than large males and fertilized more eggs.
SEXUAL CANNIBALISM, SIZE DIMORPHISM, AND COURTSHIP BEHAVIOR IN ORB‐WEAVING SPIDERS (ARANEIDAE)
  • M. Elgar
  • Biology, Medicine
    Evolution; international journal of organic…
  • 1 March 1991
TLDR
The relationship between sexual cannibalism and sexual size dimorphism may be rather more complex and the location of mating and courtship may be one factor that provides further explanation of the variation in sexual sizeDimorphism in orb-weaving spiders.
FAITHFUL WITHOUT CARE: THE EVOLUTION OF MONOGYNY
TLDR
Using a mathematical model, it is shown that monogyny as a means of increasing paternity is favored when the sex ratio is male biased, but not necessarily by high search costs.
