Potential Impacts of Low Flows on Fish Foodscapes and Production in a Braided River

River Research and Applications, EarlyView.
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, EarlyView.
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.

The First record of Megaloptera (Insecta: Neuropterida) from Sergipe state, Brazil

Entomological Communications
Megaloptera comprises approximately 400 species, of which 25 are recorded in Brazil and belong to Corydalidae and Sialidae. Here, we provide new occurrence records for Corydalus diasi Navás, 1915 (Megaloptera: Corydalidae) in Serra de Itabaiana National

An integrative phylogenomic approach to elucidate the evolutionary history and divergence times of Neuropterida (Insecta: Holometabola)

BMC Evolutionary Biology, 2020
Background The latest advancements in DNA sequencing technologies have facilitated the resolution of the phylogeny of insects, yet parts of the tree of Holometabola remain unresolved.

Aquatic biosurvey of the Lovell River on UNH land [PDF]

, 2003
We assessed the physical, chemical and biological conditions at two sites along the Lovell River on University of New Hampshire (UNH) -owned conservation land. The discharge was 4.4 m3 s-1 at Site 1 and 5.7 m3 s -1 downstream at Site 2.

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.

Seasonal investigation of heavy metals in marine fishes captured from the Bay of Bengal and the implications for human health risk assessment [PDF]

, 2016
To investigate the seasonal contamination levels and to evaluate the potential human health risks, ten heavy metals (As, Cd, Co, Cr, Cu, Mn, Ni, Pb, Se, and Zn) were measured in ten different marine fish species from the Bay of Bengal during four seasons.

More Is Not Always Better: Selective Trait Filtering Governs Assembly Under Emerging Flow Intermittency

Ecology and Evolution, Volume 16, Issue 4, April 2026.
The study examined how increasing flow intermittency affects macroinvertebrate community organisation in newly drying headwater streams. Results showed that drying selectively filters species and trait states, with resistance‐ and resilience‐related survival strategies responding differently to increasing intermittency.

Social media highlights the overlooked impact of cats on arthropods

Insect Conservation and Diversity, Volume 19, Issue 2, Page 460-465, March 2026.
The impact of domestic cats on vertebrate biodiversity is unequivocal; however, we still know little about their effects on arthropods. By analysing over 17,000 photos and videos from social media platforms (iStock and TikTok), we documented 550 predation events of cats on arthropods.
