Do crocodilians get the flu? Looking for influenza A in captive crocodilians [PDF]

Journal of Experimental Zoology Part A: Ecological Genetics and Physiology, 2008
AbstractIt is well established that several wild aquatic bird species serve as reservoirs for the influenza A virus. It has also been shown that the influenza A virus can be transmitted to mammalian species such as tigers and domestic cats and dogs through ingestion of infected birds. Another group of animals that should also be considered as potential

Injuries in deep time: interpreting competitive behaviours in extinct reptiles via palaeopathology. [PDF]

Biol Rev Camb Philos Soc
ABSTRACT For over a century, palaeopathology has been used as a tool for understanding evolution, disease in past communities and populations, and to interpret behaviour of extinct taxa. Physical traumas in particular have frequently been the justification for interpretations about aggressive and even competitive behaviours in extinct taxa.

Regeneration in the Auditory Organ in Cuban and African Dwarf Crocodiles (Crocodylus rhombifer and Osteolaemus tetraspis) Can We Learn From the Crocodile How to Restore Our Hearing?

Frontiers in Cell and Developmental Biology, 2022
Background: In several non-mammalian species, auditory receptors undergo cell renewal after damage. This has raised hope of finding new options to treat human sensorineural deafness.

How many fathers? Study design implications when inferring multiple paternity in crocodilians

Ecology and Evolution, 2022
Up to 10 males were reported to sire clutches of crocodilian eggs but review of the underlying study designs raised questions of potential upward bias of inferred sire numbers.

Is there only one species of Hepatozoon infecting Brazilian caimans? Integrative taxonomy unveiling the parasite’s diversity [PDF]

Brazilian Journal of Biology
Hepatozoon spp. are the most common haemoparasites reported from reptiles around the world, however, only six species have been described infecting crocodilians. In Brazil, Hepatozoon caimani Carini, 1909 is currently the only recognized species from the

Shared species of crocodilian trypanosomes carried by tabanid flies in Africa and South America, including the description of a new species from caimans, Trypanosoma kaiowa n. sp.

Parasites & Vectors, 2019
Background The genus Trypanosoma Gruby, 1843 is constituted by terrestrial and aquatic phylogenetic lineages both harboring understudied trypanosomes from reptiles including an increasing diversity of crocodilian trypanosomes.

Osmoregulation in Crocodilians [PDF]

American Zoologist, 1989
Recent crocodilians live primarily in freshwater habitats. However two species ( Crocodylus acutus and C. porosus ) are estuarine specialists; two others ( C. niloticus and C. johnstoni ) that are primarily found in fresh water, have estuarine populations. Routes of uptake of water and sodium include drinking, feeding and associated incidental drinking,
