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 ...

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 ...

Shell characterization of the youngest valid species of the European Eocene genus Neochelys (Pleurodira, Podocnemididae): The Spanish Bartonian Neochelys salmanticensis. [PDF]

Anat Rec (Hoboken)
Abstract The freshwater pleurodiran turtle Neochelys is the best‐represented member of Podocnemididae in the European record, being known by eight Eocene species. The youngest of them is the Bartonian (middle Eocene) Neochelys salmanticensis, from the Duero Basin (Salamanca Province, Central Spain).

Evolutionary insights in Amazonian turtles (Testudines, Podocnemididae): co-location of 5S rDNA and U2 snRNA and wide distribution of Tc1/Mariner [PDF]

Biology Open, 2020
Eukaryotic genomes exhibit substantial accumulation of repetitive DNA sequences. These sequences can participate in chromosomal reorganization events and undergo molecular cooption to interfere with the function and evolution of genomes.

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.

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.
