Some helminth parasites from Morelet\'s crocodile, Crocodylus moreletii, from Yucatan, Mexico [PDF]

Folia Parasitologica, 2001
An examination of three specimens of the Morelet's crocodile, Crocodylus moreletii Duméril et Bibron, from the Lagoon of Celestún, Yucatan, Mexico revealed the presence of the following eight helminth species: Acanthostomum americanum (Pérez Vigueras, 1956), Pelaezia loossi (Pérez Vigueras, 1956), Telorchis sp. juv., Pseudoneodiplostomum groschafti sp.

Organochlorine contaminants in Morelet’s crocodile (Crocodylus moreletii) eggs from Belize

Chemosphere, 2000
Non-viable eggs of Morelet's crocodile (Crocodylus moreletii) were collected from Gold Button (GBL) and New River lagoons (NRL) in northern Belize and screened for organochlorine (OC) compounds using gas chromatography (GC) with electron capture detection (ECD). All egg samples from both lagoons (n = 24) tested positive for one or more OCs.

Hybridization between Crocodylus acutus and Crocodylus moreletii in the Yucatan Peninsula: II. evidence from microsatellites

Journal of Experimental Zoology Part A: Ecological Genetics and Physiology, 2008
AbstractDetecting and quantifying hybridization between endangered or threatened taxa can provide valuable information with regards to conservation and management strategies. Hybridization between members of the genus Crocodylus has been known to occur in captivity and in some wild populations.

Development of an enzyme-linked immunosorbent assay for vitellogenin of Morelet's crocodile (Crocodylus moreletii)

Comparative Biochemistry and Physiology Part C: Toxicology & Pharmacology, 2006
The purpose of this study was to develop an immunoassay for vitellogenin in Morelet's crocodile (Crocodylus moreletii). Blood was collected from wild-caught crocodiles in Belize. Plasma samples from adult females taken during the breeding season were used for vitellogenin purification and samples from adult males were used for comparison.

Comparative Parasitology, 2011
Abstract Examples of nematodes parasitizing the ventral scales of Crocodylus acutus and Crocodylus moreletii in southern Belize were observed via health assessments performed on crocodiles at the American Crocodile Education Sanctuary in Punta Gorda, Belize, in August 2009.

Population status and conservation of Morelet's crocodile, Crocodylus moreletii, in northern Belize

Biological Conservation, 2000
Spotlight surveys were conducted from 1992 to 1997 to determine the population status of Morelet's crocodile, Crocodylus moreletii, in northern Belize. A total of 754 crocodiles were observed and 481.9 km surveyed (1.55/km). Encounter rates were highest in non-alluvial (8.20/km) and alluvial (6.11/km) lagoons, and considerably lower in most rivers and ...

Organochlorine contaminants in complete clutches of Morelet's crocodile (Crocodylus moreletii) eggs from Belize

Environmental Pollution, 2006
Seven complete clutches of Morelet's crocodile (Crocodylus moreletii) eggs were collected in northern Belize and examined for organochlorine (OC) pesticide residues. The primary OC detected, p,p-DDE, was found in every egg analyzed (n=175). Other OCs detected included p,p-DDT, p,p-DDD, methoxychlor, aldrin, and endosulfan I.

CONSUMPTION OF LARGE MAMMALS BY CROCODYLUS MORELETII: FIELD OBSERVATIONS OF NECROPHAGY AND INTERSPECIFIC KLEPTOPARASITISM

Southwestern Naturalist, 2007
Abstract The consumption of large (>15 kg) mammals by Morelet's crocodile (Crocodylus moreletii) is poorly documented. We present field observations of necrophagy and interspecific kleptoparasitism (defined as the stealing of food from an individual by another individual) involving the consumption of domestic cattle (Bos taurus) and Baird's tapir ...

Metals in the Caudal Scutes of Morelet’s Crocodile (Crocodylus moreletii) from the Southern Gulf of Mexico

Bulletin of Environmental Contamination and Toxicology, 2014
Caudal scutes were collected from 92 Morelet's crocodiles (Crocodylus moreletii) between May and August 2012, in three Wildlife Management and Use Units (UMAs, from its name in Spanish) and three wild sites in Campeche, Mexico. The UMAs are intensive, with an ex situ approach to manage crocodiles in captivity.
