Topic Modeling of Fatty Acid Studies: Evaluating Environmental Changes in Freshwater Ecosystems

open access: yesInternational Review of Hydrobiology, Volume 111, Issue 1, June 2026.
ABSTRACT Fatty acids (FAs) are biochemical molecules with vital structural and metabolic functions in all living organisms. Over the last decades, FA analysis in ecological studies has garnered significant attention due to its diverse applicability, such as taxonomic support for species identification, investigations on trophic interactions, and ...

Aquatic macroinvertebrates

open access: yesAtzavara, L', 2015
Despite covering only 0.8% of the Earth’s surface, freshwater biodiversity accounts for 9.5% of all described species. Aquatic macroinvertebrates, and in particular aquatic insects, are one of the most diverse faunal groups of fluvial ecosystems. Macroinvertebates are benthic invertebrates measuring more than 0.25 mm in size with a wide variety of ...

Impact of Feeding Strategies on Trophic Dynamics, Growth Performance and Sustainability of Nile Tilapia in Semi‐Intensive Aquaculture Systems

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
ABSTRACT Feed costs and limited knowledge of feeding strategies are a major constraint to the sustainability of semi‐intensive Nile tilapia aquaculture systems in sub‐Saharan Africa. In semi‐intensive systems, Nile tilapia (Oreochromis niloticus) utilizes natural pond production and supplemental feed, but their relative contributions to growth remain ...

Juvenile and Adult Three‐Spined Sticklebacks Exhibit Different Habitat Use in Shallow Baltic Sea Bays

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
ABSTRACT Three‐spined sticklebacks (Gasterosteus aculeatus) have become dominant in many Baltic Sea coastal fish assemblages, yet life‐stage‐specific habitat use remains poorly understood. We surveyed shallow water habitats along the coast of Gotland, Sweden, to examine how juvenile and adult stickleback abundances relate to variables such as submersed

Periphyton and Benthic Macroinvertebrate Response to Antimycin Piscicide During Brook Trout Restoration

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
ABSTRACT The piscicide antimycin has been used as an effective fish toxicant to eradicate nuisance fishes because it is not as detectable by fish as other chemical piscicides. We evaluated the effects of antimycin and its detoxicant, potassium permanganate, on periphyton and benthic macroinvertebrates during a brook trout (Salvelinus fontinalis ...

Evaluating Conservation Corridor Success for Rare and Common Dragonflies Using Zeta Diversity

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
This study applied the zeta diversity framework to evaluate how conservation corridors in South African timber plantations impact dragonfly assemblages, finding that corridors function similarly to natural habitats. The research findings showed that dragonfly species richness was higher in corridors than in natural areas, consistently declining with ...

Living at the Interface: Behavioral, Evolutionary and Ecological Insights of Spring Use by Highly Mobile Stygobiont Crustaceans, Troglocaris planinensis (Decapoda: Atyidae)

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
The study provides evidence that animals considered as strictly linked to subterranean habitats can exhibit behavioral responses to constraints occurring in surface environments. We studied the blind and depigmented shrimp Troglocaris planinensis in the Classical Karst using field and experimental approaches.

Species‐Specific Response of Fish Health Condition to Nutrient Enrichment in Subtropical Rivers

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
Fish condition factor (K) can be used to evaluate the effects of eutrophication. Species‐specific responses of fish K to nutrient enrichment were detected. Nutrient enrichment significantly enhanced the K value of zooplanktivorous fish, while it did not affect the K value of omnivorous fish.

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

open access: yesEcology 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.
