The sit-to-stand test provides insight into age-related functional capacity; however, there are various variants of sit-to-stand, and we do not know which of these better discriminates against age-related functional capacity. Our study aimed to compare the age-related functional capacity in older people by evaluating sit-to-stand power variants, using young individuals as a reference. A cross-sectional study was conducted in 102 adults (57 women) aged 60-80 and 105 adults (54 women) aged 20-30.

- - The study investigated the presence of antibodies to 13 livestock and zoonotic pathogens in 164 southern pudu deer in Chile from 2011 to 2023, revealing that 20.18% of wild and 30.91% of captive pudus showed exposure to these pathogens.
- - It found that fawn pudus are at a higher risk of infection compared to adults, and those living in free-range conditions are less likely to contract certain parasites.
- - This research marks the first evidence of livestock pathogen exposure in South American wildlife, indicating potential livestock-to-wildlife transmission in Chile’s temperate forests, and linking a past zoo outbreak to abortions among captive pudus.

Introduction: Herpesvirus infections have been highlighted as emerging diseases affecting wildlife health and the conservation of several taxa. Malignant catarrhal fever (MCF) and infectious keratoconjunctivitis (IKC) are two viruses that infect wild ruminants. Nevertheless, epidemiological data on herpesviruses in South American wild ruminants are limited.

- Recent research highlights a diverse range of infectious agents in wildlife, particularly in Chilean pudus, which may pose risks to human and animal health.
- The study found that various pathogens were present in blood samples from wild and captive pudus, with specific percentages indicating their occurrence in the population.
- This investigation marks the first identification of certain pathogens in wild ungulates in South America, indicating a need for further study on the potential role of pudus as infection reservoirs and transmission sources.
Interspecific interactions are key drivers of individual and population-level fitness in a wide range of animals. However, in marine ecosystems, it is relatively unknown which biotic and abiotic factors impact behavioral interactions between competing species. We assessed the impact of weather, marine productivity, and population structure on the behavioral agonistic interactions between South American fur seals (SAFSs), , and South American sea lions (SASLs), , in a breeding colony of SAFS.
