Potential Impacts of Low Flows on Fish Foodscapes and Production in a Braided River
River Research and Applications, Volume 42, Issue 6, Page 1366-1382, July 2026.ABSTRACT Changes in river discharge affect the physical composition and connectivity of habitats which, in turn, may shape the spatial distribution of fish food abundance, accessibility and quality—the ‘foodscape’—of river ecosystems. However, the influence of river flows on fish foodscapes has received very little attention from scientists. We studied

Insects and Survival: A Review of Primary and Secondary Defense Strategies
Entomologia Experimentalis et Applicata, Volume 174, Issue 7, Page 601-624, July 2026.Based on a review of three decades of literature, insect defense mechanisms are classified into primary (I) and secondary (II) mechanisms of behavioral, morphological, and chemical nature. These mechanisms have been recorded in 22 (I) and 20 (II) orders, respectively.

Trophic Redundancy and the Hidden Dietary Overlap Between Native and Invasive Stream Fishes
Ecology of Freshwater Fish, Volume 35, Issue 3, July 2026.ABSTRACT Biological invasions introduce non‐native species into natural ecosystems, often reshaping localcommunities and altering trophic interactions. In freshwater environments, such invasions can intensify resource use and threaten native fish diversity.

Environmental Quality Management, Volume 35, Issue 4, Summer 2026.ABSTRACT Mining waste water characteristically contains high concentrations of suspended solids, total metals, and nutrients. These can be treated with flocculants within settling ponds to speed up the clarification of water by settling out the suspended solids.

Urbanisation Restructures but Does Not Reduce Freshwater Pond Biodiversity
Diversity and Distributions, Volume 32, Issue 6, June 2026.ABSTRACT Aim Urbanisation is a dominant driver of landscape change leading to widespread displacement, degradation and fragmentation of habitat for native species and numerous studies have documented loss of biodiversity in response. However, most studies focus on a small range of taxa (e.g., vertebrates, plants), leaving many other groups poorly ...

The nature of allometry in an exaggerated trait: The postocular flange in Platyneuromus Weele (Insecta: Megaloptera). [PDF]
PLoS ONE, 2017 The origin and function of exaggerated traits exhibited by a great number of species with sexual dimorphism remain largely unexplored. The usual model considered as the evolutionary mechanism for the development of these structures is sexual selection ...

Diversity and Distributions, Volume 32, Issue 5, May 2026.ABSTRACT Introduction and Aim Spatiotemporal and taxonomic sampling bias in biodiversity occurrence data poses critical challenges for robust ecological inference, species distribution models (SDMs), and conservation planning. Despite the exponential growth in global biodiversity records over recent decades, these biases persist.
