Polar cod ( Boreogadus saida ) is a widespread, cold-adapted fish that plays a central role in Arctic food webs. Rising temperatures, declining sea ice, and associated changes in ecosystem dynamics may threaten this species. We investigated the influence of temperature on the pre-winter size of juvenile polar cod (an important predictor of overwinter survival and recruitment), examining hatch timing and growth across warm and...

The current generation of sequencing technologies can produce terabases of data with exceptional accuracy and speed, at a fraction of the cost of older methods. Despite this unprecedented power, adoption into aquaculture health management presents several challenges, including identifying where such capability may be optimally deployed. Here we synthesise discussions from a structured expert workshop held at the 2025 Aotearoa...

The degradation of freshwater ecosystems due to nutrient enrichment has underscored the imperative for robust water quality assessment. In this study, 11 monitoring stations were established in the critical water supply reservoir, Tappan Lake, Ohio, USA, to record the key physicochemical and biological parameters on a biweekly basis, especially in the summer. The parameters like temperature, pH, dissolved oxygen (DO), turbidit...

Background The blood brain barrier (BBB) limits effective treatment for cerebellar diseases. Region-specific parameterization and safety data for MRI-guided focused ultrasound (MRgFUS) BBB opening (BBBO) in the cerebellum are scarce. The goal of this study is to establish safety and feasibility of cerebellar BBBO for antibody delivery. Methods Mice received i.v. AF680 IgG and microbubbles immediately prior to sonication at 0.3...

Wildfires are often a natural part of many European ecosystems, but human activities through land use, other socio‐economic factors and climate change have significantly changed how fires behave. Anthropogenic climate change is already intensifying fire‐prone weather and increasing wildfire risk across Europe with risk expected to grow sharply in coming decades. Past experience suggests that human action, such as fuel manageme...

Crop diversification is a promising strategy to strengthen pest control services in agricultural landscapes. Diversifying crops may limit pests through host crop dilution or by enhancing top‐down control by their enemies. However, crop diversification may also benefit generalist pests through higher resource continuity. Using a large‐scale dataset encompassing 742 landscapes across 13 countries, we assessed the impact of lands...

Biofluorescence is widespread among marine fish but remains poorly documented in polar ecosystems. Using hyperspectral imaging, we report fluorescent emissions in two polar zoarcid eelpouts. A captive Antarctic eelpout ( Pachycara brachycephalum ) displayed uniform bright green fluorescence (~500–520 nm), whereas an Arctic eelpout ( Lycodes reticulatus ) showed weaker patterned emissions (~510–590 nm). Under identical illumina...
