The genetic origins and impacts of historical Papuan migrations into Wallacea.

Article Synopsis
- The tropical region of Wallacea was first settled by modern humans around 50,000 years ago, with Austronesian seafarers arriving approximately 3,500 years ago.
- Current populations in Wallacea show a mix of ancestries derived from both Papuan and Asian sources, suggesting interactions between local populations and Austronesian migrants, although much of the Papuan-related ancestry is traced back to migrations from New Guinea.
- Recent genetic analysis, alongside archaeological and linguistic evidence, indicates that the population history of Wallacea has been significantly influenced by the movement of Papuan genes, languages, and cultures over the last 3,500 years.

The expanding use of community science platforms has led to an exponential increase in biodiversity data in global repositories. Yet, understanding of species distributions remains patchy. Biodiversity data from social media can potentially reduce the global biodiversity knowledge gap.

Amazonia has the richest primate fauna in the world. Nonetheless, the diversity and distribution of Amazonian primates remain little known and the scarcity of baseline data challenges their conservation. These challenges are especially acute in the Amazonian arc of deforestation, the 2500 km long southern edge of the Amazonian biome that is rapidly being deforested and converted to agricultural and pastoral landscapes.

Biodiversity research in tropical ecosystems-popularized as the most biodiverse habitats on Earth-often neglects invertebrates, yet invertebrates represent the bulk of local species richness. Insect communities in particular remain strongly impeded by both Linnaean and Wallacean shortfalls, and identifying species often remains a formidable challenge inhibiting the use of these organisms as indicators for ecological and conservation studies. Here we use DNA barcoding as an alternative to the traditional taxonomic approach for characterizing and comparing the diversity of moth communities in two different ecosystems in Gabon.
