Differences in distress: Variance and production of American Crocodile (Crocodylus acutus) distress calls in Belize [PDF]

Ecology and Evolution, 2020
Acoustic communication of American Crocodiles (Crocodylus acutus) is relatively understudied. Our overall aim was to determine the acoustic structure of wild American Crocodile distress calls, distinguish call differences among size classes (hatchling ...

Sperm kinematic subpopulations of the American crocodile (Crocodylus acutus). [PDF]

PLoS ONE, 2021
There has been very limited use of computer assisted semen analysis (CASA) to evaluate reptile sperm. The aim of this study was to examine sperm kinematic variables in American crocodile (Crocodylus acutus) semen samples and to assess whether sperm ...

Spatial Ecology of the American Crocodile in a Tropical Pacific Island in Central America. [PDF]

PLoS ONE, 2016
Conservation of large predators has long been a challenge for biologists due to the limited information we have about their ecology, generally low numbers in the wild, large home ranges and the continuous expansion of human settlements.

Genetic evidence supports a distinct lineage of American crocodile (Crocodylus acutus) in the Greater Antilles [PDF]

PeerJ, 2018
Four species of true crocodile (genus Crocodylus) have been described from the Americas. Three of these crocodile species exhibit non-overlapping distributions—Crocodylus intermedius in South America, C. moreletii along the Caribbean coast of Mesoamerica,

Integrating molecular, phenotypic and environmental data to elucidate patterns of crocodile hybridization in Belize [PDF]

Royal Society Open Science, 2015
The genus Crocodylus comprises 12 currently recognized species, many of which can be difficult to differentiate phenotypically. Interspecific hybridization among crocodiles is known to occur in captivity and has been documented between some species in ...

The Spatial Ecology of Nuisance Crocodiles: Movement Patterns of Relocated American Crocodiles (Crocodylus acutus) in Guanacaste, Costa Rica [PDF]

Animals
Anthropogenic alterations of the environment have increased, highlighting the need for human–wildlife coexistence and conflict mitigation. Spatial ecology, and the use of passive satellite movement technology in particular, has been used to identify ...
