Bifoveal Vision in Anolis Lizards
Brain, Behavior and Evolution, 2008The retinas of 14 ecologically diverse species of Anolis lizards have been examined neuroanatomically. Both central and temporal foveas were observed in each eye of all species; however, the two foveas differed with regard to a number of structural and morphological characteristics. All central foveas were deep and convexiclivate, while temporal foveas

Interspecific Aggression between Lizard Competitors, Anolis cooki and Anolis cristatellus
Zeitschrift für Tierpsychologie, 2010Aggressive encounters were staged between two species of Puerto Rican lizards (Anolis cooki and Anolis cristatellus) which share the same microhabitat (syntopic). The intensity of these interspecific matches was as great as their respective conspecific matches. When the two species interacted with either “look alike” congeners (A.

Journal of Herpetology, 2008
We describe a new species of Anolis from a high-elevation locality in the Department of Cusco, Peru. This species is similar to Anolis boettgeri but differs in characters of scalation and coloration. We reanalyze Anolis albimaculatus and find this species to be a synonym of A. boettgeri. We describe variation in A.

Assessment of xylazine for euthanasia of anoles (Anolis carolinensis and Anolis distichus).
Journal of the American Association for Laboratory Animal Science : JAALAS, 2012Intracoelomic (IC) injection of xylazine was evaluated as a chemical euthanasia method for Anolis lizards (Anolis carolinensis or Anolis distichus). Lizards were allocated into 5 groups of 10 animals each. Each group was euthanized by one of these methods: 10 mg xylazine (100 mg/mL) IC; 10 mg xylazine and 0.5 mg acepromazine (10 mg/mL) IC; 10 mg ...

Genetic Divergence between Anolis carolinensis and Its Cuban Progenitor, Anolis porcatus
Journal of Herpetology, 1980An electrophoretic comparison was made between Anolis carolinensis from Texas and Georgia and Anolis porcatus from Cuba. At five of 35 presumptive gene loci the Cuban population may be distinguished from the North American population. The Nei genetic distance (o) estimate between the Cuban and North American populations is 0.165 which is slightly above

Anolis Sagrei and Anolis Cristatellus in Southern Florida: A Case Study in Interspecific Competition
Ecology, 1984This study examined the possibility of interspecific competition between Anolis sagrei and A. cristatellus, two introduced species of lizards that co—occur in the vicinity of Miami, Dade County, Florida. In an area of sympatry, structural habitat use differed significantly between the two species. Comparison of habitat use by sympatric A.

Anolis Lizards of the Caribbean
1995Abstract The Anolis lizards of the Caribbean are ideally suited for the study of evolutionary ecology. Offering fascinating insights into the more than 150 species dispersed throughout the Caribbean islands, Jonathan Roughgarden details the differences between species in a wide range of behavioral and physical characteristics, including ...
