Guidelines for the purification and characterization of extracellular vesicles of parasites

Journal of Extracellular Biology, Volume 2, Issue 10, October 2023., 2023
Abstract Parasites are responsible for the most neglected tropical diseases, affecting over a billion people worldwide (WHO, 2015) and accounting for billions of cases a year and responsible for several millions of deaths. Research on extracellular vesicles (EVs) has increased in recent years and demonstrated that EVs shed by pathogenic parasites ...

A framework for quantifying soundscape diversity using Hill numbers

Methods in Ecology and Evolution, Volume 13, Issue 10, Page 2262-2274, October 2022., 2022
Abstract Soundscape studies are increasingly used to capture landscape‐scale ecological patterns. Yet, several aspects of soundscape diversity remain unexplored. Although some processes influencing acoustic niche usage may operate in the 24‐hr temporal domain, most acoustic indices only capture the diversity of sounds co‐occurring in sound files at a ...

Seasonal dietary niche contraction in coexisting Neotropical frugivorous bats (Stenodermatinae)

Biotropica, Volume 52, Issue 4, Page 749-757, July 2020., 2020
Abstract Tropical dry forests are characterized by punctuated seasonal precipitation patterns that drive primary production and the availability of fruits, seeds, flowers, and insects throughout the year. In environments in which the quantity and quality of food resources varies seasonally, consumers should adjust their foraging behavior to maximize ...
