Pseudobarbus kubhekai sp. nov., a new redfin (Teleostei, Cyprinidae) from KwaZulu-Natal, South Africa [PDF]

Zoosystematics and Evolution
A recent phylogeographic analysis of the remnant populations of Pseudobarbus quathlambae from Lesotho and South Africa revealed the existence of three allopatrically distributed lineages: (i) one in eastern Lesotho, (ii) one in Mohale, central Lesotho ...

Biodiversity of aquatic organisms in the Mekong Delta, Vietnam

Biodiversity Data Journal, 2023
The Mekong River is the 10th largest river in the world. It is recognised as the most productive river in Southeast Asia and economically essential to the region, with an estimated 60-65 million people living in the lower Mekong Basin. The Mekong Delta within Vietnam is considered a highly vulnerable ecosystem under threat from increasing anthropogenic

Semi-supervised learning advances species recognition for aquatic biodiversity monitoring

Frontiers in Marine Science
Aquatic biodiversity monitoring relies on species recognition from images. While deep learning (DL) streamlines the recognition process, the performance of these method is closely linked to the large-scale labeled datasets, necessitating manual ...

Hemp Cultivation and Crop Diversification: Implications for Ecosystem Services in Kentucky

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT This study examines the ecosystem benefits of expanding hemp cultivation by assessing its impact on crop diversity. Using scenario‐based simulations and fixed‐effect panel regressions with county‐level data in Kentucky, we find that increased hemp acreage tends to enhance crop diversity, improving water quality and bird diversity.

Cascade Dams and Seasonality Jointly Structure Gut Microbiome Biogeography in Saurogobio punctatus

Microorganisms
Cascade dams fragment river habitats, but how seasonal hydrology modulates the biogeography and assembly of fish gut microbiota remains unclear. We surveyed gut bacterial communities of the omnivorous fish Saurogobio punctatus across 10 reaches separated

Description of a new goatfish species, Upeneus randalli n. sp. (Mullidae), from the Persian Gulf, with remarks and identification keys for the genus Upeneus

Scientia Marina, 2011
The number of species of the goatfish genus Upeneus from the western Indian Ocean has increased considerably due to recent taxonomic efforts. Here we describe a new species, Upeneus randalli n.

Application of a novel schema for describing fossil fern foliage and investigating taxonomic and morphological change across the Cretaceous–Paleogene boundary in western North America

American Journal of Botany, EarlyView.
Abstract Premise The Chicxulub asteroid impact at the Cretaceous–Paleogene (K–Pg) boundary triggered a mass extinction 66 million years ago. Ferns thrived in the aftermath of the extinction, evidenced by the well‐documented “fern spore spike.” However, fern macrofossil records across the K–Pg boundary are less understood.

Habitat partitioning shapes divergent bacterial community assembly and carbon–nitrogen functional responses under cascade-dam fragmentation and seasonality

Water Research X
Cascade-dam systems impose repeated hydrological discontinuities that convert a river continuum into alternating reservoir–river segments, enhancing environmental heterogeneity and longitudinal gradients beyond the influence of a single dam.

Ecosystem-Based Management, Ecosystem Services and Aquatic Biodiversity: Theory, Tools and Applications

, 2020
Environmental problems are very often wicked problems: they are persistent, they have no clear end, and involve moral choices resulting in winners and losers.
