Anatomy of the Respiratory System and Heart of the Sloth (Choloepus hoffmanni) of Costa Rica
Revista Ciencias Veterinarias, 2021 The two-toed sloth (Choloepus hoffmanni) faces various diseases related to the respiratory and circulatory system. Thus, prior knowledge of anatomy becomes relevant since it contributes to the study and interpretation of medical images and surgical ...

Ecomorphological determinations in the absence of living analogs:The predatory behavior of the marsupial lion (Thylacoleo carnifex) as revealed by elbow joint morphology [PDF]
, 2016 Thylacoleo carnifex, or the “pouched lion” (Mammalia: Marsupialia: Diprotodontia: Thylacoleonidae), was a carnivorous marsupial that inhabited Australia during the Pleistocene.

The orobasal organ (of Ackerknecht): A bizarre structure of the mammalian oral cavity
Journal of Morphology, Volume 284, Issue 6, June 2023., 2023 In 1912, Ackerknecht discovered and described an epithelial invagination behind the lower medial incisors in different mammalian species. This rudimentary structure might be a vestiagial organ which lost its physiological function. Named after its discoverer the “orobasal organ of Ackerknecht” is widely unknown in the scientific world.

A comparison of staff presence and signage on zoo visitor behavior
Zoo Biology, Volume 42, Issue 3, Page 407-415, May/June 2023., 2023 The presence of uniformed zoo staff reduced negative behaviors by zoo visitors more effectively than signage. Abstract Many zoos favor the use of signage to encourage learning and positive visitor experiences as well as discourage negative behaviors by visitors because of its simplicity, relatively low maintenance needed, and low cost. However, current

Gender and Age, but Not Visual Context, Impact Wildlife Attitudes and Perceptions of Animals in Zoos
Journal of Zoological and Botanical Gardens, 2023 People’s attitudes toward wildlife may impact their behaviors in support of conservation. We surveyed people in the United States to determine if gender, age, or visual contexts commonly seen in zoos impacted wildlife attitudes and perceptions of animals

Release and follow-up of a rehabilitated two-toed sloth (Choloepus hoffmanni) in a tropical dry forest in Ecuador [PDF]
Neotropical Biology and Conservation, 2022 We present the first records of the post-release follow-up and monitoring of a rehabilitated two-toed sloth (Choloepus hoffmanni) as well as freezing behavior and an inferred antagonistic interaction for this species.

Shotgun Mitogenomics Provides a Reference Phylogenetic Framework and Timescale for Living Xenarthrans [PDF]
, 2015 Xenarthra (armadillos, sloths, and anteaters) constitutes one of the four major clades of placental mammals. Despite their phylogenetic distinctiveness in mammals, a reference phylogeny is still lacking for the 31 described species. Here we used Illumina

Diversity and Distributions, Volume 29, Issue 5, Page 613-628, May 2023., 2023 Abstract Aim A current biogeographic paradigm states that climate regulates species distributions at continental scales and that biotic interactions are undetectable at coarse‐grain extents. However, advances in spatial modelling show that incorporating food resource distributions are important for improving model predictions at large distribution ...
