REPRODUCTIVE CYCLE STAGE ASSESSMENT IN THE TWO-TOED SLOTH (CHOLOEPUS HOFFMANNI), PRELIMINARY RESULTS

Journal of Zoo and Wildlife Medicine
The number of two-toed sloths (Choloepus hoffmanni) has significantly decreased in the last years. Deepening the knowledge of this tropical mammal's reproductive physiology is essential to improve captive breeding within conservation programs for this species.

Body mass predicts isotope enrichment in herbivorous mammals. [PDF]

Proc Biol Sci, 2018
Carbon isotopic signatures recorded in vertebrate tissues derive from ingested food and thus reflect ecologies and ecosystems. For almost two decades, most carbon isotope-based ecological interpretations of extant and extinct herbivorous mammals have ...

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.

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

Identifying hotspots and priority areas for xenarthran research and conservation

Diversity and Distributions, Volume 28, Issue 12, Page 2778-2790, December 2022., 2022
Abstract Aim Limited funds for conservation and research require the development of prioritization schemes. Traditionally, biodiversity metrics were used to delineate priority areas; however, a growing realization emphasizes that logistic factors should be also considered.

Iteratively mapping ancient DNA to reconstruct highly divergent mitochondrial genomes: An evaluation of software, parameters and bait reference

Methods in Ecology and Evolution, Volume 13, Issue 11, Page 2419-2428, November 2022., 2022
Abstract The ability to obtain ancient DNA (aDNA) from extinct species has greatly improved our ability to study their evolutionary histories. Most aDNA studies focus on mitochondrial DNA for both population‐level and species‐level insights, due to its relatively high abundance and increased obtainability.

Sloths host Anhanga virus-related phleboviruses across large distances in time and space. [PDF]

Transbound Emerg Dis, 2020
Abstract Sloths are genetically and physiologically divergent mammals. Phleboviruses are major arthropod‐borne viruses (arboviruses) causing disease in humans and other animals globally. Sloths host arboviruses, but virus detections are scarce. A phlebovirus termed Anhanga virus (ANHV) was isolated from a Brazilian Linnaeus's two‐toed sloth (Choloepus ...

Comparative study of the evolution of cancer gene duplications across fish

Evolutionary Applications, Volume 15, Issue 11, Page 1834-1845, November 2022., 2022
Abstract Comparative studies of cancer‐related genes not only provide novel information about their evolution and function but also an understanding of cancer as a driving force in biological systems and species’ life histories. So far, these studies have focused on mammals.
