An integrative revision of the genus Isognathotermes (Termitidae: Cubitermitinae) with description of seven new species and four new subspecies Open
Cubitermitinae species whose workers have enteric valves of the fungifaber and finitimus patterns were previously gathered into the genus Isognathotermes. Here, we revise this genus, combining the morphological and anatomical features of a…

A DNA metabarcoding workflow for the detection of terrestrial gastropods from ingested DNA Open
DNA metabarcoding is a powerful approach for assessing biodiversity and unravelling trophic interactions, particularly in the context of biological invasions where introduced predators may impact native communities. However, the analysis o…

Experimental assessment of the predation pressure by the exotic flatworm <i>Obama nungara</i> in its introduced range Open
Land planarians are carnivorous predators that feed mainly on soil macrofauna such as earthworms, gastropods, and other land planarians. Several land planarian species have become invasive worldwide and pose a threat to soil biodiversity. …

First records of the true Sicilian slug Deroceras panormitanum (Eupulmonata: Agriolimacidae) in France and mitochondrial sequences of three additional species of the genus Deroceras Open
The genus Deroceras (Eupulmonata: Agriolimacidae) is the richest genus of slugs in terms of described species and as such represents a challenge for taxonomic knowledge, endemic species conservation and invasive species management. Until n…

Population Dynamics of the Exotic Flatworm <i>Obama nungara</i> in an Invaded Garden Open
Population dynamics and the way abundance fluctuates over time may be key determinants of the invasion success of an introduced species. Fine‐scale temporal monitoring of invasive species is rarely carried out due to the difficulties in co…

Evolutionary history of soil-feeding Neotropical termites reveals recent divergences linked to geologic-climatic influences Open
The Neotropics harbor a diverse array of flora and fauna shaped by a complex geological and climatic history. It includes marine invasions, pulses of Andean uplift, glaciations, and the uplift of the Panama Isthmus. These events have shape…

Challenges of molecular barcode-based identification of earthworm specimens for biodiversity assessment Open
Specimen identification at the species level is a critical challenge for understanding community structure and conserving biodiversity. The use of mitochondrial DNA barcodes, in addition to morphology, has proven to be a useful tool for ea…

Diversity of insect pests of common bean and pigeon pea in the Republic of Congo revealed by DNA barcoding Open
In Central Africa, the development of leguminous crops is accompanied by a proliferation of pests, such as seed-beetles (Coleoptera: Chrysomelidae: Bruchinae). Integrated biological control against insect pests requires a preliminary phase…

Spatiotemporal variations of Chlamys islandica larval shell morphometry between 2000 and 2018 in a depleted coastal scallop fishing area Open
Bivalves larval shell morphometry can provide valuable information on their planktonic (PI-Prodissoconch I) and early benthic life (PII). We examined spatial (at two scales: fishing sub-areas and exploited beds) and temporal variability (b…

Identification of a queen primer pheromone in higher termites Open
It is long established that queens of social insects, including termites, maintain their reproductive dominance with queen primer pheromones (QPPs). Yet, the QPP chemistry has only been elucidated in a single species of lower termites. By …

Insights into coastal phytoplankton variations from 1979 to 2018 derived from Ba/Ca records in scallop shells (Chlamys islandica) from a fishing ground in the northern Gulf of St. Lawrence Open
Bivalve growth is affected by phytoplankton quality and availability, but long-term, coastal environmental time series related to these parameters are often lacking. Therefore, it is crucial to develop methods to accurately quantify trends…
