Journal of BCOMING's Field Mission in Guinea: Part 2

The BCOMING project aims to conduct a thorough evaluation of biodiversity across various anthropogenic gradients and scales. In Cambodia, the scientific team is focusing on the bat interface as a key component, not only to assess zoonotic risk but also to understand broader ecological dynamics. Among the features being evaluated are the communities of bats' ectoparasites, which play important roles in bats’ ecosystem health and disease transmission dynamics between them. Bats harbor a diverse array of ectoparasites, including fleas, flies, ticks, and mites for examples, and are an integral part to the intricate relationships between them, their hosts, and the environment. Despite being often overlooked, these ectoparasites appear to be essential ecological components and can serve as indicators of ecosystem health. While poorly understood, these ectoparasites, through occasional changes of host, could facilitate the transmission of infectious diseases within bat colonies. Two families, Streblidae and Nycteribiidae, stand out for their unique adaptations and behaviors within the bat ecosystem.

Mammals, a vital component of terrestrial ecosystems, are facing drastic declines due to anthropogenic changes in landscapes. With many species secluded in protected areas and facing extreme conservation status, there is a growing need for rapid, cost-effective, and noninvasive methods to monitor their populations. Within BCOMING, it is important that we use the most accurate techniques to establish biodiversity assessment as it is a core component in our research on pathogen circulation. Our team at Université de Liège in Belgium, consisting of Dr Pauline van Leeuwen and Prof. Johan Michaux, delves into the scientific literature for non-invasive methods to detect mammalian species in the field. They published the first scientific article supported by the BCOMING consortium. This study compares conventional survey methods and the emerging environmental DNA (eDNA) metabarcoding technique for mammal biodiversity assessment.

In the heart of Southeast Asia lies Cambodia, a country teeming with biodiversity that has long captivated the imaginations of scientists and conservationists alike. Nestled within this rich tapestry of ecosystems, a dedicated research team from Université de Liège embarks on an exciting journey to unravel the mysteries of Cambodia's wildlife microbiome at the human-animal interface. Our team at Université de Liège in Belgium, consisting of Dr Pauline van Leeuwen and Prof. Johan Michaux, is leading the microbiome component of the BCOMING project. We aim to improve our knowledge of the influence of biodiversity and on microbiomes structure and zoonotic risks.
