Summary: This study evaluated the cryopreservation effects on the semen of oncilla and ocelot, comparing two extenders. Ocelot spermatozoa showed higher quality after thawing, while major defects including acrosome injuries were observed in both species. The study also found that oncilla semen contamination by urine may reduce sperm cryoresistance, and recommended further investigation on extenders for this species.

Summary: Understanding the trophic structure of carnivore communities is crucial for species management and conservation, especially in endangered habitats like tropical montane forests. In this study, camera-trap data was used to investigate the occupancy patterns of ocelots in the transitional habitat between different land tenures, and the influence of prey occupancy on ocelot presence. The results showed that habitat preferences did not significantly affect ocelot occupancy, but landscape variables such as vegetation structure, land tenure, distance to roads, and anthropogenic factors played a role in prey occupancy. Ocelots had a low site occupancy and were strongly associated with the presence of Central American agoutis, exhibiting a higher overlap with nocturnal prey species. The study emphasizes the importance of habitat structure and prey availability for the persistence of ocelots across natural-anthropogenic interfaces.

Summary: The complete genome of the first anellovirus infecting the wild felid Leopardus pardalis (ocelot) was identified through high-throughput sequencing protocols followed by Sanger sequencing validation. Phylogenetic analysis classified the virus into two distinct clusters related to previously described Felidae anelloviruses.

Summary: This article describes the first report of hypertrophic cardiomyopathy phenotype in a captive leopardus pardalis. The condition was characterized by concentric hypertrophy of the left ventricle and was detected through cardiological evaluation with echocardiogram and cardiac auscultation. The patient initially received treatment with clopidogrel and atenolol, but later developed congestive heart failure and was switched to pimobendan and furosemide, which stabilized the condition. After one year, the patient showed slight improvement but remained stable.

Summary: The purpose of this research was to provide basic information about ocelots in northwestern Mexico, including population density, relative abundance, and home range. The study used photo-trapping to collect data, and the results highlighted the importance of continued research in the Northern Jaguar Reserve for maintaining a viable ocelot population in northwestern Mexico.

Summary: This study analyzes the skull and mandibular remains of the felid species Leopardus pardalis in late Pleistocene rocks in Uruguay, providing the first reliable documented fossil record of this species in the country. The findings shed light on the paleobiology and paleoecology of L. pardalis during the late Pleistocene in Uruguay.

Summary: The article describes an incident where a wild ocelot attacked a group of people in Southeastern Peru. Based on evidence and scientific literature, the authors hypothesize that a disease affecting the central nervous system or human-induced trauma may explain this abnormal behavior.

Summary: This study is the first conservation genetics study on ocelots in Costa Rica, finding relatively high genetic diversity in Costa Rican ocelots and no significant genetic substructure. Comparisons with jaguars and pumas in the country and ocelots in Belize also showed higher genetic diversity in Costa Rican ocelots.

Summary: In times of severe drought, carnivores may have increased aggressive interactions due to heightened competition for valuable resources that cannot be easily divided, such as water.

Summary: Two-toed sloths usually live in trees, but they sometimes come down to mineral licks on the ground to feed and obtain minerals. This behavior can make them vulnerable to predators, like the ocelot mentioned in this report, which attacked an adult sloth at a mineral lick in the Ecuadorian Amazon. This predation event is unusual because sloths usually visit mineral licks at night.

Summary: The study aims to assess biodiversity conservation goals in the United States and integrates habitat quality and quantity through the development of the National Habitat Condition Index (HCI). It was found that functional habitat is independent of protection status, as working lands also provide significant value.

Summary: This study evaluated the effects of two different techniques (direct vitrification in cryovials and solid-surface vitrification) for the preservation of ear skin from the ocelot. The results showed that solid-surface vitrification had a better cellular quality and is suitable for the preservation of ocelot skin.

Summary: This study observed the visitation of Linnaeus's two-toed sloth at mineral licks in the Amazon rainforest using camera traps and analyzed the visitation patterns. The results suggest that sloth visitation at mineral licks may be influenced by habitat selection factors such as elevation, slope, and distance from rivers and streams. This study provides important data and natural history information on sloth visitation at mineral licks and contributes to our understanding of the ecological significance of mineral licks.

Summary: Urban waterbodies play a significant role in avian ecology, acting as hotspots for bird diversity in urban landscapes. Parks with waterbodies attract more bird species and resident forest birds, while surroundings with waterbodies can support a higher richness of forest bird species. These findings emphasize the importance of creating and maintaining urban waterbodies for biodiversity conservation in highly urbanized areas.
