Cost of parasite exposure depends on host ontogeny 寄生接觸的代價依賴於宿主發育階段

Ecological Entomology, Volume 51, Issue 3, Page 592-603, June 2026.
The cost of parasite exposure varies across host developmental stages, demonstrating that ontogeny influences the expression of non‐consumptive effects (NCEs). Mite exposure resulted in consumptive effects in fly eggs and NCEs in early‐stage pupae; mite longevity was comparable when provisioned with pupae or water but increased when provisioned with ...

Evaluating and Advancing the Use of Shore‐Based Observers for Scientific Sampling and Catch Verification in High‐Volume Fisheries

Fisheries Management and Ecology, Volume 33, Issue 3, Page 612-629, June 2026.
ABSTRACT Shore‐based observers are increasingly being used in place of at‐sea observers to monitor and sample commercial fisheries catch. However, few evaluations assess whether these programs meet their stated goals or how to optimize them, and industry data are rarely tested for accuracy despite serving as the foundation for catch accounting.

Effects of biosecure macroalgae in formulated feeds on the gut bacterial microbiome of abalone Haliotis midae

Journal of the World Aquaculture Society, Volume 57, Issue 3, June 2026.
Abstract Dietary macroalgae are known to contribute directly and indirectly to the gut microflora of abalone. However, certain farms require macroalgae to be made biosecure to eliminate microbiota and reduce their risk of acting as a vector for potential disease before being included as a dietary ingredient in aquafeeds.

Tissue‐Specific Plasticity of DNA Methylation Across Intertidal Microhabitats in Juvenile Mussels (Mytilus californianus)

Molecular Ecology, Volume 35, Issue 11, June 2026.
ABSTRACT Epigenetic modifications to DNA are proposed to underpin plastic responses to environmental change, and the manner in which DNA methylation contributes to plasticity likely differs among tissues. However, few studies have investigated tissue‐specific DNA methylation responses to ecologically relevant environmental stressors in natural settings.

Into the Wild: Farm‐Derived Energy and Nutrients Enter Marine Food Webs With Carrying Capacity Implications for Aquaculture Management

Reviews in Aquaculture, Volume 18, Issue 3, June 2026.
ABSTRACT Marine aquaculture is expanding globally, yet its interactions with surrounding ecosystems remain complex and insufficiently understood. This study reviews the fluxes of energy and nutrients from three major aquaculture systems: finfish cages, suspended bivalves, and seaweed farms and considers their implications for ecosystem functioning and ...
