For the study, adult flies were collected from organic waste-rich agricultural environments in Jeddah and reared under controlled laboratory conditions. Adult and larval morphology was documented using stereomicroscopy, based on established diagnostic characters. DNA was extracted from larvae, and partial…
Invasive species experts are alarmed by the state’s signing of a vague $1 million contract with engineers who will be tasked with figuring out what imports are most prone to hosting new invasive species. The contract, signed in June, was awarded…
The assay targets a diagnostic single-nucleotide polymorphism within the Internal Transcribed Spacer 2 (ITS2) region of ribosomal DNA. According to the authors, Mohamed Kader Haidara, Gleb N. Artemov and Igor V. Sharakhov, the method was designed to be rapid, sensitive, specific and suitable for…

Learn about plants that look bizarre as well as plants that have common names that send a chill down your spine. We connect ag professionals with the latest crop research to help them make economically and environmentally wise crop management…
A histological study of two laboratory-reared sesarmid crabs documents how the stomach and hepatopancreas develop from the first zoeal stage to the crab stage. Subject of Research: Histological development of the stomach and hepatopancreas in two Episesarma crab species from…
As a generalization of stage-based matrix models, integral projection models (IPMs) have been used to describe the size-based dynamics of wildlife and fisheries populations. Although some matrix models have explicitly included species interactions, few IPMs have expanded beyond single species,…
Aquatic macrophyte communities were assessed in 53 lakes in Wisconsin, U.S.A. along environmental and land use development gradients to determine effects human land use perturbations have on aquatic macrophytes at the watershed and riparian development scales. Species richness and relative frequency were…
Brazil's Bioinvasão Brasil platform has compiled 339 marine non-native and cryptogenic species and more than 6,200 georeferenced records since launching in 2019.
Researchers identified the first population of the invasive *Wasmannia auropunctata* in the Canary Islands, finding that it is genetically distinct from other Western Palearctic populations.
Invasive species and the science of controlling them: how they spread and the damage they do, from lionfish, cane toads and pythons to invasive insects and plants.
