Under threat in North African reservoirs: The decline of the Algerian barb, Luciobarbus callensis (Actinopterygii, Cypriniformes, Cyprinidae), in Tunisia as a case study Despite numerous studies on stocked freshwater fishes in Tunisian reservoirs, the population status of native species remains poorly documented. This study aims to address a critical knowledge gap by ...

Figure 1 in Willighagen & Jongejans (2025): "Schematic overview of the data model of the Library of Identification Resources, showing how the metadata of identification resources and associated checklists are represented following FAIR principles. The catalog entry proper, shown in the left box, mostly consists of bibliographical data expressed using the BIBO ontology (in blue) and domain-specific data using the AC ontology (in purple). Optionally, a taxonomic checklist of the resource can be associated with a catalog entry, indicating which taxa are included. For this data, a simplified example is shown in the right box, where red, orange, yellow, and green represent different taxonomic ranks, respectively family, genus, species, and subspecies."

Rectangular boxes indicate the different invertebrate functional feeding groups. Green and red arrows depict increasing and decreasing effects respectively and line width depicts the correlation strength (positive and negative standardised estimates for green and red arrows, respectively). Values for invertebrate organic material (OM) consumption and periphyton were derived from a 1 month growth rate, phytoplankton from a monthly time-weighted average and plant and floating algal beds biomass from direct collection."

Study of Dramatic Flying Insect Declines Reinforces Earlier Findings - Beyond Pesticides Daily News Blog (Beyond Pesticides, May 17, 2022) With public awareness of an ongoing ‘insect apocalypse’ growing, one of the first anecdotes people often note is how many fewer bugs are found splatted onto their car windshield than in the past. In a recent survey, conservation groups in Britain are finding evidence of insect declines in exactly that place, providing scientific backing for these concerning suspicions. Between 2004 and 2021, 58.5% fewer flying insects were squashed onto car license plates. “The results from the Bugs Matter study should shock and concern us all,” says Paul Hadaway, conservation director at Kent Wildlife Trust, which conducted the study alongside UK organization Buglife. “We are seeing declines in insects which reflect the enormous threats and loss of wildlife more broadly across the Country. These declines are happening at an alarming rate and without concerted action to address them we face a stark future. Insects and pollinators are fundamental to the health of our environment and rural economies.” The survey was conducted primarily through citizen science, utilizing the “Bugs Matter” mobile app, and a sampling grid, referred to as a ‘splatometer’ that is affixed to a car’s license plate. Data was retrieved from trips taken by citizen […]
