Behavioral convergence and adaptive radiation: effects of habitat use on territorial behavior in Anolis lizards
Johnson, Michele A.; Revell, Liam J.; Losos, Jonathan (Wiley-Blackwell, 2009)Most studies of adaptive radiations focus on morphological aspects of differentiation, yet behavior is also an important component of evolutionary diversification, often mediating the relationship between animal ecology ... -
A Phylogenetic Perspective on Foraging Mode Evolution and Habitat Use in West Indian Anolis Lizards
Lara, Ada Chamizo; Johnson, Michele A.; Revell, Liam J.; Leal, Manuel; Rodríguez Schettino, Lourdes; Losos, Jonathan (Elsevier, 2008)Although many descriptive studies of foraging mode have been performed, the factors that underlie the evolution of foraging mode remain poorly understood. To test the hypothesis that foraging mode evolution is affected by ... -
A Phylogenetic Test for Adaptive Convergence in Rock-dwelling Lizards
Revell, Liam J.; Johnson, Michele A.; Schulte, James A. II; Kolbe, Jason J.; Losos, Jonathan (Blackwell Publishing, 2007)Phenotypic similarity of species occupying similar habitats has long been taken as strong evidence of adaptation, but this approach implicitly assumes that similarity is evolutionarily derived. However, even derived ... -
What Drives Variation in Habitat Use by Anolis Lizards: Habitat Availability or Selectivity?
Johnson, Michele A.; Kirby, Rebecca; Wang, Sue; Losos, Jonathan (NRC Research Press, 2006)Geographic variation in habitat availability may drive geographic variation in a species' habitat use; alternatively, species adapted to particular habitat characteristics may use a habitat regardless of its availability ...
