Remaining forests on the Central Highlands of Madagascar-Endemic and endangered aquatic beetle fauna uncovered.

Madagascar is known for its high endemism and as many as 90% of this unique diversity are forest-dwellers. Unfortunately, the forest cover of Madagascar is decreasing at an alarming rate. This decrease can also affect aquatic insects, but our knowledge on aquatic insect diversity and distribution on Madagascar are limited.

Win-win opportunities combining high yields with high multi-taxa biodiversity in tropical agroforestry.

Resolving ecological-economic trade-offs between biodiversity and yields is a key challenge when addressing the biodiversity crisis in tropical agricultural landscapes. Here, we focused on the relation between seven different taxa (trees, herbaceous plants, birds, amphibians, reptiles, butterflies, and ants) and yields in vanilla agroforests in Madagascar. Agroforests established in forests supported overall 23% fewer species and 47% fewer endemic species than old-growth forests, and 14% fewer endemic species than forest fragments.

Land-use trajectories for sustainable land system transformations: Identifying leverage points in a global biodiversity hotspot.

Sustainable land-system transformations are necessary to avert biodiversity and climate collapse. However, it remains unclear where entry points for transformations exist in complex land systems. Here, we conceptualize land systems along land-use trajectories, which allows us to identify and evaluate leverage points, i.

Taxonomic revision of the genus of Madagascar (Coleoptera, Dytiscidae, Copelatinae): the non- group species.

The genus Erichson, 1832 (Coleoptera, Dytiscidae, Copelatinae) of Madagascar is revised in two parts. This review is restricted to the species that have fewer than ten elytral + one submarginal stria, including all species except those of the species group. Both morphological and molecular (mitochondrial COI) data are used in an integrative taxonomic approach.

Spread and strain determination of Varroa destructor (Acari: Varroidae) in Madagascar since its first report in 2010.

Varroa destructor is a major pest in world beekeeping. It was first detected in Madagascar in 2010 on the endemic honeybee Apis mellifera unicolor. To evaluate V.
