Afrotropical forests are undergoing massive change caused by defaunation, i.e., the human-induced decline of animal species, most of which are frugivorous species.

Using a socio-ecological system (SES) approach in a forest-swamp-savannah mosaic within the Bas-Ogooué Ramsar site in Gabon, we assess how human populations participate in landscape dynamics over time. We first conducted a remote sensing analysis to produce a land-cover map representing the biophysical dimension of the SES.

- Many diseases that can make people or animals sick start in wild animals, so scientists need to keep an eye on these animals and their germs.
- Catching samples from wild animals can be hard, but there's a cool method called xenosurveillance that uses blood-sucking bugs, like tsetse flies, to help collect these samples.
- In a study in Tanzania, scientists found that tsetse flies had fed on different animals and discovered germs, including some that can be harmful, showing that this method can help us learn more about diseases in wild animals.
Article Synopsis
- The study aimed to assess the prevalence of antibiotic resistance in Enterobacteriaceae from wild mammals in Gabon's national parks, focusing on both intrinsic and acquired resistance.
- Researchers identified 90 enterobacterial isolates from 130 colonies, with Escherichia coli being the most common species (61%), followed by other species like Enterobacter cloacae and Proteus mirabilis.
- Findings indicated that most resistant strains were wild type with intrinsic resistance, whereas acquired resistance was limited, particularly in E. coli (11%) and E. cloacae (3%).
About 60% of emerging infectious diseases in humans are of zoonotic origin. Their increasing number requires the development of new methods for early detection and monitoring of infectious agents in wildlife. Here, we investigated whether blood meals from hematophagous flies could be used to identify the infectious agents circulating in wild vertebrates.

A total of 10,033 hematophagous flies were captured. The Glossinidae, with six different species identified, was the most abundant group and constitutes about 60% of the captured flies compared to the Stomoxys (6 species also identified) and Tabanidae with 28% and 12%, respectively.

A growing number of studies have described the presence of different Wolbachia strains within a same host. To date, no naturally occurring multiple infections have been recorded in terrestrial isopods.
