Sodium sulfite can reliably induce chemical hypoxia without toxic effects in the model sea anemone species, Exaiptasia diaphana

Limnology and Oceanography: Methods, Volume 24, Issue 10, October 2026.
Abstract Climate change is accelerating the deoxygenation of aquatic ecosystems, so understanding its effects on biological processes is increasingly critical. An emerging method for inducing hypoxia during experimentation utilizes sodium sulfite (SSI) to scavenge oxygen; however, it remains unclear if hypoxia‐inducing concentrations of SSI are toxic ...

The complete mitochondrial genomes of the freshwater mussel Ortmanniana ligamentina (Lamarck, 1819): male and female mitotypes

Mitochondrial DNA. Part B. Resources
Freshwater mussels of the Unionida order are important to freshwater ecosystems but are highly imperiled worldwide. Improving our understanding of these species is crucial to their continued conservation.

Does bigger mean sicker? A systematic review and meta‐analysis of the intraspecific relationship between host body size and parasite infection across vertebrate taxa

Oikos, Volume 2026, Issue 10, October 2026.
Elucidating the determinants of parasite infection levels of individuals within a population is a basic but important step for understanding the roles of parasites in natural systems. Among intraspecific studies on vertebrate hosts and metazoan parasites, host body size (length/mass) is probably the most frequently reported factor determining parasite ...

Integrating and assessing metacommunity drivers of ecosystem function and resilience in benthic algal systems

Oikos, Volume 2026, Issue 10, October 2026.
Understanding the scales and mechanisms by which species composition interacts with ecosystem functions is critical for forecasting the effects of environmental perturbations on ecosystem services. However, the linkages between what regulates the ecosystem functions of dispersal‐capable networks of communities (metacommunities) and what regulates a ...

The complete mitochondrial genome of Potomida acarnanica (Kobelt, 1879)

Mitochondrial DNA. Part B. Resources
Freshwater mussels (Bivalvia, Unionida) play essential roles in the well-functioning of ecosystems, even providing essential services to humans. However, these bivalves face numerous threats (e.g.

Dynamic response of communities and ecosystem functions to ecosystem engineering and multiple stressors in a marine mussel bed

Oikos, Volume 2026, Issue 10, October 2026.
Ecosystem engineers are crucial to the development of coastal ecosystem communities and functions. However, a better understanding of how environmental stressors affect ecosystem engineering and thereby influence communities and ecosystem dynamics is needed. We conducted an in situ experiment in a blue mussel Mytilus spp.

The Cost of Self‐Sufficiency: Could New Zealand be Self‐Sufficient in Food Consumption?

Journal of the Royal Society of New Zealand, Volume 56, Issue 5, October 2026.
Ensuring that New Zealand can sustainably meet its future food needs requires an understanding of the interaction between domestic demand trends, trade and the capacity of national production systems. Although New Zealand is a major exporter of dairy, meat, fruit and other primary products, rising food insecurity, changing dietary preferences and ...

Crushing and Cutting: Shape Variation and Morphological Integration Between the Claws of Two Swimming Crab Species (Brachyura: Portunidae)

Acta Zoologica, Volume 107, Issue 4, Page 450-459, October 2026.
ABSTRACT This study investigated shape variations and morphological integration between the components of crusher and cutter claws in two species of swimming crabs, Callinectes danae and Callinectes ornatus. The propodi and dactyli of the claws were analysed in males and females of both species, using geometric morphometric techniques to identify ...

Integrating Acoustic Telemetry and Stable Isotope Data Reveals Overlap in Resource Use by Large‐Bodied Fishes in a Temperate Lake

Ecology of Freshwater Fish, Volume 35, Issue 4, October 2026.
ABSTRACT Temperate lake ecosystems undergo seasonal shifts that disproportionately alter the availability of suitable habitat for fishes of different thermal guilds. While many studies have investigated fish habitat use patterns, few have estimated the degree to which fish species overlap in space across seasons from a three‐dimensional perspective ...

Monitoring of Endangered Freshwater Mussels in Sweden Using Digital PCR

Environmental DNA
Freshwater mussels are traditionally monitored by visual observations which is time‐consuming and can be difficult depending on water conditions. Environmental DNA (eDNA) is an attractive alternative since it can detect a species in the water without ...
