1. Behavioral type–environment correlations in the field: a study of three-spined stickleback

Author:
Pearish, Simon; Hostert, Lauren; Bell, Alison M.
Source:
Behavioral ecology and sociobiology 2013 v.67 no.5 pp. 765-774
ISSN:
0340-5443
Subject:
fish; microhabitats; phenotypic plasticity; rivers
Abstract:
... Behavioral type–environment correlations occur when specific behavioral types of individuals are more common in certain environments. Behavioral type–environment correlations can be generated by several different mechanisms that are probably very common such as niche construction and phenotypic plasticity. Moreover, behavioral type–environment correlations have important ecological and evolutionar ...

2. Evolution of mating systems and sexual size dimorphism in North American cyprinids

Author:
Pyron, M.; Pitcher, T. E.; Jacquemin, S. J.
Source:
Behavioral ecology and sociobiology 2013 v.67 no.5 pp. 747-756
ISSN:

Subject:
Cyprinidae; body size; dimorphism; females; fish; males; mating systems; models; phylogeny; spawning; sperm competition; testes
Abstract:
... Mating systems evolve with sexual size dimorphism (SSD) in many animals. Mating systems with males larger than females occur when males compete for female access or guard territories, while mating systems with group mating tend to occur in species where females are the same size or larger than males. In addition to variation in SSD with mating system, sperm competition varies among mating systems ...

3. The benefit of obligate versus facultative strategies in a shrimp–goby mutualism

Author:
Lyons, Patrick J.

Behavioral ecology and sociobiology 2013 v.67 no.5 pp. 737-745
ISSN:

Subject:
Gobiidae; burrows; coevolution; fish; foraging; mutualism; predation; predators; shrimp
Abstract:
... Obligate mutualists are predicted to benefit more from mutualism than facultative mutualists and harbor traits that help derive this extra benefit. I tested these predictions with a shrimp–goby mutualism. Individual shrimp (Alpheus floridanus) construct burrows that are shared with individual gobiid fishes that warn shrimp when emergence from burrows is unsafe. The benefit to gobies is refuge from ...
