| ectromelia in morelet's crocodile from belize. | two morelet's crocodiles (crocodylus moreletii) captured on 21 march 1997 and 20 april 1998 in the new river system, belize exhibited ectromelia of one forelimb. external and radiograph examination appears to indicate limb agenesis of unknown etiology, as there is no apparent scarring or skeletal trauma. these two individuals represent the only cases of missing limbs from 642 individuals captured in this study and to our knowledge, the first reported cases in morelet's crocodile. several factors ... | 1999 | 10073362 |
| organochlorine contaminants in morelet's crocodile (crocodylus moreletii) eggs from belize. | 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. primary contaminants were p,p-dde and methoxychlor, detected in 100% and 29% of the eggs examined, respectively. concentrations of individual oc contaminants ... | 2000 | 10705543 |
| dde in eggs of two crocodile species from belize. | organochlorine (oc) residues were recently detected in nonviable morelet's crocodile (crocodylus moreletii) eggs from northern belize. to further the assessment of contaminant exposure in belizean crocodiles, nonviable morelet's crocodile eggs (n = 11) from southern belize and american crocodile (crocodylus acutus) eggs (n = 12) from the coastal zones of belize were screened for 20 ocs. results indicated p,p-dde to be the most prevalent oc (96% occurrence) in eggs examined, with concentrations r ... | 2000 | 11141295 |
| ticks from a morelet's crocodile in belize. | parasitism of crocodilians by ticks has rarely been reported, and to our knowledge only seven published accounts exist. on 3 july 1999, we collected four ticks from a subadult morelet's crocodile (crocodylus moreletii) captured in northern belize. these were identified as amblyomma dissimile (one female), and amblyomma sp. (two nymphs, one larva). the crocodile was captured on land approximately 100 m from water, and all four ticks were attached to loose skin on the lateral surface of the tail. ... | 2001 | 11763751 |
| mercury in morelet's crocodile eggs from northern belize. | recent studies have examined mercury accumulation in crocodilians. however, though most researchers have focused on tissue concentrations, few have examined mercury levels in crocodilian eggs. in july 1995, we analyzed mercury in 31 nonviable morelet's crocodile ( crocodylus moreletii) eggs collected from eight nests across three localities in northern belize. all eggs were found to contain mercury. based on an individual egg basis, mean concentration of mercury for all three localities was amon ... | 2002 | 11910460 |
| some helminth parasites from morelet's crocodile, crocodylus moreletii, from yucatan, mexico. | 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. n. (all trematodes), dujardinascaris helicina (molin, 1860), contracaecum sp. type 2 larvae, micropleura sp. and paratrichosoma recurvum (solger, ... | 2001 | 11266135 |
