Interspecies gene flow is a key evolutionary process for the adaptation of long-lived species to new environmental conditions [PDF]

open access: yes, 2017
La especiación por hibridación y la hibridación introgresiva entre especies del mismo género se reconocen cada vez más como un mecanismo que contribuye a la generación de novedades evolutivas y a la promoción de amplitud de nicho ecológico.

Host species and age‐specific variation on Hepatozoon prevalence and its effect on body condition in two Neotropical crocodiles

open access: yesWildlife Biology, Volume 2025, Issue 5, September 2025.
Many populations of species belonging to the order Crocodilia are threatened due to illegal trafficking, indiscriminate hunting, and habitat loss and degradation affecting crocodilian health and parasitic load. Although several studies have revealed that crocodiles, caimans, and alligators are frequently infected by Hepatozoon spp., the results from ...

Variabilidad genética de poblaciones en cautiverio de Crocodylus moreletii (Crocodylia: Crocodylidae) mediante el uso de marcadores microsatelitales Genetic variability in captive populations of Crocodylus moreletii (Crocodylia: Crocodylidae) using microsatellites markers

open access: yesRevista de Biología Tropical, 2012
Crocodylus moreletii representa un emblema para los ecosistemas tropicales de México pero actualmente está amenazada por extinción. Sorprendentemente, hay una falta de información de su constitución genética, que debe ser evaluada para un manejo ...

Conquering the crush: A novel tool for holding crocodilian jaws open

open access: yesWildlife Society Bulletin, Volume 48, Issue 3, September 2024.
Crocodilians possess the strongest bite force of all extant animals, and this jaw‐closing pressure poses a challenge and safety risk for people working with them. We designed and tested a device for holding alligator jaws open that allows for safe positioning within the mouth and is adaptable to both widen and collapse the gape of the mouth.

Population genetic structure of Morelet’s and American crocodiles in Belize:Hybridization, connectivity and conservation [PDF]

open access: yes
Hybridization can influence the evolutionary potential of wild species and can be especially detrimental where one species is abundant, and the other much rarer.

Genomic and environmental insights and conservation challenges for two hybridizing iconic crocodile species across Mexico: Crocodylus acutus and C. moreletii

open access: yesAnimal Conservation, Volume 27, Issue 3, Page 308-323, June 2024.
Understanding hybridization is key for conservation of wild species, yet it is still a controversial issue in conservation. We discern geographic and temporal patterns of introgression, migration, and demography for Crocodylus acutus, C. moreletii, and their hybrid lineages.

Motivations behind wild animal consumption in social media in Mexico: A case study

open access: yesPeople and Nature, Volume 6, Issue 2, Page 676-686, April 2024.
Abstract Wildlife trade is a worldwide threat to biodiversity. It is a complex problem, and to deal with it, one must analyse its constituting factors, some of which are specific to certain geographic areas. Although Mexican laws have prohibited selling wild products, Mexico is still both a source and consumer of exotic wildlife; however, there is ...

Efecto de los llamados preeclosionales de Crocodylus moreletii en la duración y el número de eclosiones

open access: yesActa Universitaria, 2019
Diferentes nidadas ex situde Crocodylus moreletiise sometieron a sesiones de playbacks. Estos variaron con base en la vocalización que emiten, ya sea al inicio o al final del proceso de eclosión, así como en la tasa de repetición (rápida o lenta).
