Selection of High-quality Sperms by the Nanotechnological Method of Magnetic Activation in Brazilian Cervids [PDF]

, 2021
Cervids show a high degree of abnormalities in their sperm cells. Thus, this study aimed to select high-quality spermatozoa using magnetic-activated sperm sorting (MASS) compared to density gradient centrifugation (DGC) by assessing the post-selection ...

Medium and large mammal responses to fire in a neotropical savanna system in Guyana

Biotropica, Volume 57, Issue 1, January 2025.
Mammal responses to fire—both natural and man‐made—in an Indigenous savanna landscape in Guyana were researched with transects for animal signs and live sightings. Species richness showed a non‐linear relationship with time since fire, likely due to differing responses from individual species, which may be explained by habitat preference and post‐fire ...

Selective impacts of subsistence hunting on mammal communities in Manu National Park, Peru

Biotropica, Volume 56, Issue 5, September 2024.
We analyzed change in species relative abundance and functional composition of mammal communities, including non‐hunted species, along a hunting pressure gradient and included potential confounding environmental and disturbance gradients (distances to rivers, lakes, settlements, and trails; NDVI at survey point).

Tropical timber plantations as habitat for ground‐dwelling mammals: A camera‐trapping assessment in Central Panama

Biotropica, Volume 56, Issue 4, July 2024.
We used camera traps to survey five timber plantation type located on a highly disturbed landscape in Central Panama. We fitted hierarchical glmm and occupancy models to contrast species richness and their use of the plantations. We found relatively low species richness, characterized by small‐bodied mammals, and low occupancy values for the majority ...

Cathemerality: a key temporal niche

Biological Reviews, Volume 99, Issue 2, Page 329-347, April 2024.
ABSTRACT Given the marked variation in abiotic and biotic conditions between day and night, many species specialise their physical activity to being diurnal or nocturnal, and it was long thought that these strategies were commonly fairly fixed and invariant.

Detection of Theileria and Babesia in brown brocket deer (Mazama gouazoubira) and marsh deer (Blastocerus dichotomus) in the State of Minas Gerais, Brazil

Veterinary Parasitology, 2011
Intraerythrocytic protozoan species of the genera Theileria and Babesia are known to infect both wild and domestic animals, and both are transmitted by hard-ticks of the family Ixodidae. The prevalences of hemoprotozoa and ectoparasites in 15 free-living Mazama gouazoubira, two captive M.
