Introduction
In Indonesia, the rugged isthmus connecting the Bird’s Head Peninsula with the rest of New Guinea is one of the last wilderness areas remaining in Southeast Asia. Our aims are to study the diversification processes of terrestrial and marine communities prevailing at the heart of the Coral Triangle. This program is jointly conducted in partnership with LIPI-P2O, POLTEK-KP Sorong, LIPI-RCB, UNIPA and IRD.

Ellochelon vaigiensis is a monotypic, catadromous, and widespread species throughout Indo-Pacific region. Taxonomy of the species is ancient and somewhat confused by morphological resemblance. Here, we present and compare the morphological characteristics of E. vaigiensis from 3 distinct areas, respectively from the type locality (Waigeo Island, Ra...

Species inventories are the building blocks of our assessment of biodiversity patterns and human impact. Yet, historical inventories based on visual observations are often incomplete, impairing subsequent analyses of ecological mechanisms, extinction risk and management success. Environmental DNA (eDNA) metabarcoding is an emerging tool that can pr...

Increasing speed and magnitude of global change threaten the world’s biodiversity and particularly coral reef fishes. A better understanding of large-scale patterns and processes on coral reefs is essential to prevent fish biodiversity decline but it requires new monitoring approaches. Here, we use environmental DNA metabarcoding to reconstruct wel...

Biodiversity knowledge is widely heterogeneous across the Earth’s biomes. Some areas, due to their remoteness and difficult access, present large taxonomic knowledge gaps. Mostly located in the tropics, these areas have frequently experienced a fast development of anthropogenic activities during the last decades and are therefore of high conservati...

Article
Pleistocene Climatic Fluctuations (PCF) are frequently highlighted as important evolutionary engines that triggered cycles of biome expansion and contraction. While there is ample evidence of the impact of PCF on biodiversity of continental biomes, the consequences in insular systems depend on the geology of the islands and the ecology of the taxa...
Article
Environmental DNA (eDNA) has the potential to provide more comprehensive biodiversity assessments, particularly for vertebrates in species-rich regions. However, this method requires the completeness of a reference database (i.e. a list of DNA sequences attached to each species), which is not currently achieved for many taxa and ecosystems. As an a...

DNA barcoding opens new perspectives on the way we document biodiversity. Initially proposed to circumvent the limits of morphological characters to assign unknown individuals to known species, DNA barcoding has been used in a wide array of studies where collecting species identity constitutes a crucial step. The assignment of unknowns to knowns as...

In many developing countries, aquaculture is key to ensuring food security for millions of people. It is thus important to measure the full implications of environmental changes on the sustainability of aquaculture. We conduct a double meta-analysis (460 articles) to explore how global warming and antimicrobial resistance (AMR) impact aquaculture....

Coelacanth fishes of the genus Latimeria are the only surviving representatives of a basal lineage of vertebrates that originated more than 400 million years ago. Yet, much remains to be unveiled about the diversity and evolutionary history of these ‘living fossils’ using new molecular data, including the possibility of ‘cryptic’ species or unknown...

With 1172 native species, the Indonesian ichthyofauna is among the world’s most speciose. Despite that the inventory of the Indonesian ichthyofauna started during the eighteen century, the numerous species descriptions during the last decades highlight that the taxonomic knowledge is still fragmentary. Meanwhile, the fast increase of anthropogenic...

Seven pairs of species-specific primers, including...

The ontogenetic trajectory of Pangasius djambal resembles that of Pangasianodon hypophthalmus. At the start of exogenous feeding (48 h after hatching), larvae of P. djambal (8.5 mm TL, 4.5 mg WM) exhibit a large gape (17.5% TL), they possess long oral spines (100 µm) but no pectoral fins. However, the spines do not overhang from the mouth, and gape...

Narrow hybrid zones are generally subjected to the action of two forces: dispersal, which tends to homogenise the hybridising taxa, and selection against hybrids, which, in contrast, produces steep clines of introgression for diagnostic markers. Although differences between sexes in dispersal abilities or in susceptibility to hybrid counterselectio...
