Parasitic Fauna of Free-Living <i>Chelonoidis denticulatus</i> From the Rio Acre Ecological Station and the Municipality of Cruzeiro do Sul, Western Amazon, Brazil. [PDF]

Vet Med Int
Tortoises, such as Chelonoidis denticulatus, are described as hosts of many parasites, such as helminths and ticks of the genus Amblyomma, which are important vectors of rickettsial infection in Brazil. Additionally, the high consumption of meat from these animals in Acre results in a high risk of zoonotic outbreaks due to contact with the hosts and ...

Neuroanatomical study of the podocnemidid turtle Neochelys arenarum (Pleurodira), from the early Eocene of France. [PDF]

Anat Rec (Hoboken)
Abstract Neochelys is an exclusively European Eocene podocnemidid genus belonging to a linage that reached this continent at the early Eocene. The so far available anatomical information about it is relatively abundant, especially considering that of its shell, at least partially preserved for the eight valid species currently considered.

Socioeconomic drivers of wild meat consumption in the city of Iquitos, Peru. [PDF]

Conserv Biol
Abstract Wild meat represents a vital source of micro‐ and macronutrients for forest‐dwelling people; however, city dwellers with access to animal protein from different animals may also consume large amounts of wild meat as part of their customs and traditions, to diversify their diets, to maintain connections to their rural kin, and to access meat ...

To What Extent Can Life History Strategies Inform Reptile Conservation Planning? [PDF]

Ecol Evol
Conservation planners must effectively target interventions to reduce the extinction risk of species. If we can use a species' life history strategies to predict their responses to interventions, this offers a promising approach to better understand species extinction risks and conservation potential.

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates. [PDF]

Biol Rev Camb Philos Soc
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...
