Revisiting the species list of freshwater fish in Israel based on DNA barcoding. [PDF]
Ecol Evol, 2023 This study established a DNA barcoding database for freshwater fishes in Israel. Molecular and morphological species identifications were compared, and discrepancies were found for samples in five genera, which suggests significant reconsiderations to the species list in Israel and the region.

Global Patterns and Drivers of Freshwater Fish Extinctions: Can We Learn From Our Losses? [PDF]
Glob Chang BiolNearly one‐third of freshwater fish species are currently at risk of extinction, with 100 species already lost. This study examines extinction patterns over the past 165 years, identifying habitat modification and loss, pollution, and invasive species as key drivers.

eDNA metabarcoding reveals differences in fish diversity and community structure in heterogeneous habitat areas shaped by cascade hydropower. [PDF]
Ecol Evol, 2023 Freshwater ecosystems are under great threat from humans, among which habitat heterogeneity is the most obvious, being one of the important reasons for the decline of fish diversity. This phenomenon is particularly prominent in the Wujiang River, where the continuous rapids of the mainstream have been divided into 12 mutually isolated segments by 11 ...

Environmental DNA Reveals the Fish Community Structure Exhibited Instability and Trend of Miniaturization in the Xijiang River Basin of the Guizhou. [PDF]
Ecol EvolMonitoring of fish communities is of great significance for the management and sustainability of river ecosystems. Environmental DNA (eDNA) metabarcoding technology has been demonstrated to be a highly sensitive biomonitoring tool. Nevertheless, it has seldom been tested in mountainous rivers within the geographically complex Karst region.

Surprising spatiotemporal stability of a multi-peak fitness landscape revealed by independent field experiments measuring hybrid fitness. [PDF]
Evol Lett, 2020 Abstract The effect of the environment on fitness in natural populations is a fundamental question in evolutionary biology. However, experimental manipulations of both environment and phenotype at the same time are rare. Thus, the relative importance of the competitive environment versus intrinsic organismal performance in shaping the location, height,

Sexual Dimorphism in Fin Size and Shape in North American Killifish. [PDF]
Ecol EvolSexual dimorphism is pervasive in North American killifish in the size and shape of their dorsal and anal fins. These fins perform multiple functions, including grasping females during spawning, dominance displays towards rival males, and courtship towards females. Sexual selection may share a common direction across this group.

Overlooked Invaders? Ecological Impacts of Non‐Game, Native Transplant Fishes in the United States
Fisheries, Volume 48, Issue 2, Page 62-71, February 2023., 2023 Nonnative fishes can cause ecological impacts as invasive species, but identifying which nonnative species have harmful impacts is critical to prioritizing management and policy responses. Here, we characterized the state of knowledge on the impacts of a possibly overlooked group of invasive species in the United States: non‐game native transplant ...

Small‐bodied fish species from the western United States will be under severe water stress by 2040
Conservation Science and Practice, Volume 5, Issue 1, January 2023., 2023 Regions with highest anticipated water stress are low in overall freshwater biodiversity but high rates of imperiled species. Abstract Human need to appropriate freshwater in combination with climate change has intensified the rapid decline in freshwater biodiversity.

Journal of Biogeography, Volume 49, Issue 6, Page 1193-1203, June 2022., 2022 Abstract Aim Migratory freshwater fishes are those that must access discrete habitats to complete their life cycles. Freshwater fish migrations occur around the world and provide numerous ecosystem services for humans and natural systems; however, many migratory species are in decline globally.
