AI Article Synopsis
- A new genus and species, Rhithrops capensis, has been discovered in the Matjies River, Western Cape, South Africa.
- This genus shows distinct features that set it apart from closely related South African genera, including unique body structures and adaptations for life in aquatic environments.
- The species was found in deep water near aquatic plants and has specialized leg and claw structures for a benthic lifestyle, and a revised identification key for South African dryopid genera is included.
Article Abstract
Rhithrops capensis gen. et sp. nov. is described from the Matjies River, in the Cedeberg range of the Western Cape Province, South Africa. The new genus is apparently related to the South African endemic genera Rapnus Grouvelle, 1899 and Strina Redtenbacher, 1867, but exhibits a number of distinct character states, including gibbosities outside the sublateral pronotal furrows and a transversely upturned labral apex, unique within the family. Rhithrops gen. nov. was collected from around the roots of aquatic plants in fast flowing deep water runs, as well as being sampled in nocturnal drift nets. The new species has relatively long legs and well-developed tarsal claws, and appears to be adapted to an entirely aquatic, benthic existence. A revised key is provided to the dryopid genera of South Africa.

Four novel halophilic archaeal strains CGA53, CG83, FCH27, and SEDH24 were isolated from a soda lake and two saline lakes in China, respectively. Strain CGA53 showed the highest 16S rRNA gene similarity (92.6%) to Salinilacihabitans rarus AD-4, and the other three strains were found to be related to Halalkalicoccus species with similarities of 97.

Six strains isolated from muskmelon and watermelon seedlings affected by stem rot and wilting in Serbia were reported as based on pathogenicity, LOPAT and cell wall fatty acid analyses. Recent bacterial isolates from cucurbit crops displaying -like symptoms in Alabama, USA, were identified as , prompting polyphasic re-evaluation of the Serbian strains. All six strains were found to cause severe disease in watermelon and squash seedlings under greenhouse conditions.

Wastewater treatment plants (WWTPs) could be conduits of polyfluoroalkyl substances (PFAS) contaminants in the environment. This study investigated the fate of 40 PFAS compounds across nine municipal WWTPs with varying treatment capacity and processes. High concentrations of perfluoroalkyl carboxylic acids (PFCAs) and perfluoroalkyl sulfonic acids (PFSAs) were detected in wastewater, with the ratio of their total concentrations (∑PFCAs/∑PFSAs) always greater than one.

A Gram-stain-negative, non-spore-forming, rod-shaped, obligately anaerobic bacterium, designated strain BP47G, was isolated from the hindgut of a silver drummer () fish collected from the Hauraki Gulf, New Zealand. Phylogenetic analysis based on the 16S rRNA gene sequence of the isolate indicated that it belonged to the family in the phylum . The gene sequence of BP47G was most similar to with 95.

The demand for mobile coverage with adequate signal quality has triggered criticism due to the maturity of the Internet's diffusion in today's society. However, with the deployment of 5G networks, even 5G NSA by 4G LTE, the complexity of the operating environment of mobile networks has increased. To evaluate the behavior of mobile networks in terms of signal quality and other important metrics for mobile telephony, we developed a dataset consisting of 33 radio parameters that can collect up to 736,974 records generated daily by smartphones and tablets.
