Drones: Emergence of a transformative technology for island rodent eradications

Conservation Science and Practice, EarlyView.
Drones have emerged as a potentially powerful tool to address an ongoing need for alternative rodent eradication solutions on remote islands. This potential has now been demonstrated in a diverse set of operations across the Pacific. In the coming decades, this novel toolset also offers the possibility to step beyond existing paradigms and imagine a ...

Exposure to the Oestrogenic Pollutant 17α‐Ethinyl Estradiol (EE2) Does Not Alter the Behaviour of a Coastal Marine Fish, Cristiceps australis

Ethology, EarlyView.
Environmental contamination with the synthetic estrogen 17α‐ethinyl estradiol (EE2) is widespread in coastal ecosystems, yet behavioural effects in marine fishes remain poorly understood. We exposed southern crested weedfish (Cristiceps australis) to low and high EE2 concentrations for 14 days and assessed boldness and anxiety using a refuge‐use assay.

Characterisation of a phylogenetically distinct PL25 family ulvan lyase from a seaweed biomass enriched metagenome

The FEBS Journal, EarlyView.
Ulvan is a polysaccharide available from green seaweed with beneficial properties for various applications. The full potential of ulvan requires enzymatic degradation of the polymer, thus producing ulvan oligosaccharides. This study expands the armoury of characterised ulvan lyases.

Compound‐Specific Stable Isotope Analysis Reveals Population‐Specific Differences in Chinook Salmon Trophic Level and Basal Resource Use in the Northeast Pacific

Fisheries Oceanography, EarlyView.
ABSTRACT Chinook salmon exhibit far‐flung and disparate population‐specific marine migrations that have made it difficult to assess their trophic ecology. In this study, we collected returning and resident subadult Fraser River Chinook salmon in 2018 and 2019 from population groups with different known run‐timings (spring, summer, and fall) and marine ...

Acute freshwater CO2 exposure does not impair seawater transfer in three different sizes of Atlantic salmon (Salmo salar) subjected to different photoperiod manipulations

Journal of Fish Biology, EarlyView.
Abstract There is a growing interest in Atlantic salmon (Salmo salar) aquaculture to extend the time fish are reared in freshwater (FW) recirculating aquaculture systems (RAS), producing larger FW salmon that can then be induced to undergo smoltification before transfer into marine net pens for grow‐out and harvest.
