Anthropogenic habitat transformation has led to population declines and increasing isolation of populations of many species, particularly top predators, where small and fragmented populations often experience limited dispersal and reduced genetic diversity. Jaguars ( Panthera onca ), for example, have lost half of their historical range and most populations outside the Amazon biome are small, isolated and highly threatened. He...

In modern sows, litter size often exceeds the number of functional teats. Therefore, many farms retain surplus piglets within the litter. The present study evaluated the effect of cross-fostering biological litters with up to two surplus piglets relative to functional teats, allowing piglet replacement until day three of lactation. Females were selected ( n = 201) at farrowing and evenly distributed among treatments: +0 (numbe...

The production of biogas as a strategy for biotransforming large volumes of waste into bioenergy is one of the alternatives for reducing greenhouse gases. Metabarcoding analysis aims to understand the role of microbiota from the beginning of the process in the success of biogas production. This study compared microbial diversity and metabolic prediction in a pilot plant producing biogas for vehicular use, utilizing organic sol...

Abiotic and biotic stresses profoundly affect global agricultural production. Climate change and escalating global temperatures are expected to increase the prevalence of these stressful conditions. The metabolism of plants is influenced by animal neurotransmitters, which play crucial roles in the regulation of responses to stress and the enhancement of stress tolerance. Among these neurotransmitter-like compounds are catechol...

Purpose This study investigated the occurrence of vector-borne pathogens in free-living opossums ( Didelphis albiventris and Didelphis aurita ) from São Paulo State, Brazil, with emphasis on Babesia spp., Hepatozoon spp., and Ehrlichia spp. Methods Blood samples from 115 opossums (95 D. albiventris and 20 D. aurita ) were analyzed using parasitological and molecular approaches. Conventional PCR assays were performed for Babesi...

The future of how we understand and manage ecosystems largely depends on direct and continuous observations that connect local territories to planetary processes. Latin America (LATAM: Mexico, Central and South America, and the Caribbean) hosts ecosystems critical for regulating global carbon, water, and energy cycles. However, persistent underinvestment in science and technology hampers the long‐term monitoring capacity neede...
