A peirosaurid mandible from the Albian–Cenomanian (Lower Cretaceous) of Algeria and the taxonomic content of Hamadasuchus (Crocodylomorpha, Peirosauridae)

Papers in Palaeontology, Volume 9, Issue 2, March/April 2023., 2023
Abstract Peirosaurids form an extinct clade of terrestrial crocodylomorphs from the Cretaceous of Africa and South America. Here, we describe a new mandibular ramus attributable to Hamadasuchus cf. rebouli from the Albian–Cenomanian of La Gara Samani (Algeria).

Macrogeographic genetic variation in broad‐snouted caiman (Caiman latirostris)

Journal of Experimental Zoology Part A: Ecological Genetics and Physiology, 2008
AbstractBroad‐snouted caiman's (Caiman latirostris) geographic distribution comprises one of the widest latitudinal ranges among all crocodilians. In this study we analyzed the relationship between geographic distance (along the species latitudinal range) and genetic differentiation using DNA microsatellite loci developed for C.

Using functional traits to identify conservation priorities for the world's crocodylians

Functional Ecology, Volume 37, Issue 1, Page 112-124, January 2023., 2023
Read the free Plain Language Summary for this article on the Journal blog. Abstract Over half of all crocodylians are threatened with extinction, with many species considered to be functionally extinct throughout their historical ranges. How such losses impact crocodylian functional diversity (FD) and its conservation is poorly understood, but can be ...

Effects of In Vivo Exposure to Roundup® on Immune System of Caiman latirostris. [PDF]

, 2012
The present study aimed to evaluate the effect of Roundup® (RU, glyphosate-based formulation) on some parameters of the immune system and growth of Caiman latirostris. Seventy-two caimans (20-day-old) from Proyecto Yacaré (Gob. Santa Fe/MUPCN) were used.

Giant dwarf crocodiles from the Miocene of Kenya and crocodylid faunal dynamics in the late Cenozoic of East Africa

The Anatomical Record, Volume 305, Issue 10, Page 2729-2765, October 2022., 2022
Abstract We describe two new osteolaemine crocodylids from the Early and early Middle Miocene of Kenya: Kinyang mabokoensis tax. nov. (Maboko, 15 Ma) and Kinyang tchernovi tax. nov. (Karungu and Loperot, 18 Ma). Additional material referable to Kinyang is known from Chianda and Moruorot. The skull was broad and dorsoventrally deep, and the genus can be

Intraspecific isotopic niche variation in broad-snouted caiman (Caiman latirostris)

Isotopes in Environmental and Health Studies, 2013
Strategies to minimise intraspecific competition are common in wild animals. For example, individuals may exploit food resources at different levels of the food chain. Analyses of stable isotopes are particularly useful for confirming variations in an intraspecific niche because the chemical composition of animals tends to reflect both the food ...

Cross-species microsatellite amplification in South American Caimans (Caiman spp and Paleosuchus palpebrosus)

Genetics and Molecular Biology, 2006
Microsatellite DNA markers have been used to assess genetic diversity and to study ecological behavioral characteristics in animals. Although these markers are powerful tools, their development is labor intensive and costly.

Análisis multivariado de los cambios hemáticos y morfométricos de Caiman latirostris y Caiman yacare según especie, sexo y estación del año [PDF]

, 2010
Para optimizar la cría en cautiverio de los caimanes es necesario encontrar dietas que aceleren su crecimiento. Las dietas pueden evaluarse a través de los aumentos del peso, dimensiones corporales e indicadores nutricionales sanguíneos.

Extending the paleontology-biogeography reciprocity with SDMs: Exploring models and data in reducing fossil taxonomic uncertainty. [PDF]

PLoS ONE, 2018
Historically, studies aimed at prospecting and analyzing paleontological and neontological data to investigate species distribution have developed separately. Research at the interface between paleontology and biogeography has shown a unidirectional bias,

Effective population size of broad-snouted caiman (Caiman latirostris) in Brazil: A historical and spatial perspective

Global Ecology and Conservation, 2021
Caiman latirostris has a large geographic distribution, that includes Argentina, Bolivia, Brazil, Paraguay, and Uruguay. In Brazil illegal hunting and land use change have caused population decline, relatively well documented in the last three decades ...
