Renal Trichodinosis in the Japanese Rice Fish, Oryzias latipes: First Report and Phylogenetic Classification

Journal of Fish Diseases, Volume 49, Issue 11, November 2026.
ABSTRACT Investigation of a disease outbreak in a hobbyist's medaka (Oryzias latipes) collection led to the detection of Trichodina sp. in the kidney tubuli of individual fish. Based on this observation, a thorough clinical workup, including native microscopy, histopathology and molecular genetics, was conducted.

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 ...

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 ...

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 ...

Scale Invariant Patterns of Life History Strategies of Riverine Mussels Are Shaped by Hydrological Factors

Freshwater Biology, Volume 71, Issue 10, October 2026.
ABSTRACT Understanding how ecological patterns and processes scale across space is essential for predicting biodiversity structure, particularly in riverine systems where hierarchical networks and directional flow generate nested environmental gradients that influence community assembly.
