Diet of juvenile skipjack herring Alosa chrysochloris: Ontogenetic shifts, predator–prey size ratios and mouth gape allometry

Journal of Fish Biology, EarlyView.
Abstract The skipjack herring Alosa chrysochloris inhabits Gulf of Mexico drainages, primarily the Mississippi River Basin, and estuarine environments in the Gulf of Mexico. The trophic ecology of the skipjack herring is poorly understood, therefore we quantified the length, mouth gape and gut contents of juvenile skipjack herring from the Mississippi ...

Individual and combined effects of shading and habitat complexity on benthic macroinvertebrate communities in a mesocosm stream experiment (São Paulo, Brazil)

Restoration Ecology, EarlyView.
Abstract Introduction Agricultural activities are a major driver of biodiversity loss and ecosystem degradation in subtropical streams, often altering macroinvertebrate community structure and associated ecosystem functions. Although restoration strategies increasingly target these impacts, the relative importance of riparian shading and in‐stream ...

Profundum solomoni (Amphipoda: Uristidae) Exhibits a Disjunct Geographic Distribution at Hadal Depths Across the San Cristobal Trench, Santa Cruz Trench and Nova Canton Trough

Zoologica Scripta, EarlyView.
ABSTRACT Hadal environments (> 6000 m ocean depths) are often viewed as isolated locations with high species endemism due to limited dispersal. However, molecular studies continue to reveal greater complexity that questions historical perceptions. Recent population genetic studies focused on scavenging amphipods have identified broadly distributed ...

Benthic and hyporheic invertebrate community responses to seasonal flow recession in a groundwater-dominated stream [PDF]

, 2011
Natural hydrological variability in lotic ecosystems can include prolonged periods of flow recession. A reduction in discharge is accompanied by abiotic changes in benthic and hyporheic habitats, often including reductions in s habitat availability ...

Bromelicolous Habit and Phoresy of Ostracoda in a Species of Treefrog From the Brazilian Cerrado

Austral Ecology, Volume 51, Issue 5, May 2026.
ABSTRACT Some plants develop phytotelmata, specialized structures that retain water and form small aquatic ecosystems harbouring diverse organisms. Bromeliads (Bromeliaceae) are classic examples, as their leaf axils provide suitable habitats for bacteria, algae, protozoa, invertebrates and vertebrates, including anurans.

The first known troglomorphic, eyeless spider wasp (Hymenoptera: Pompilidae): Troglopompilus miracaecatus gen. et sp. nov. from the Nullarbor Caves, Western Australia

Austral Entomology, Volume 65, Issue 2, May 2026.
Abstract Surveys of caves of the Nullarbor Plain, Western Australia, revealed a remarkable assemblage of exceptionally well‐preserved mummified arthropods, comprising Araneae, Blattodea, Coleoptera and Chilopoda, all of which exhibit high levels of troglomorphism, lacking eyes and showing a number of other adaptations.

Microcrustaceans in rice fields: A scientometric analysis from 1977 to 2019

Anais da Academia Brasileira de Ciências, 2022
We evaluated the worldwide trends in studies of the active and dormant forms of microcrustaceans in rice fields, and the potential of this environment as a stock of diversity through a scientometric analysis. Web of Science and Scopus databases were used
