Peterman's productivity method for estimating dynamic reference points in changing ecosystems
(Oxford University Press, 2022-03-15)
Target and limit reference points are fundamental management components used to define sustainable harvest strategies. Maximum Sustainable Yield (MSY) and the precautionary principle underpin many reference points. Non-proxy ...
Age, growth, and sexual dimorphism of the Southern Hemisphere long-finned pilot whale (Globicephala melas edwardii)
(Oxford University Press, 2022-02-03)
Knowledge of population biological parameters can contribute to assessing the resilience of a population in the face of increasing anthropogenic pressures. Southern Hemisphere long-finned pilot whales (Globicephala melas ...
Does Landscape Structure Affect the Presence of Woodland Specialist Pollinators in Farmland? Implications for Agri-Environment Scheme Design
(Royal Irish Academy, 2022-03-16)
Some pollinator species found in agricultural areas are strongly dependent on surrounding areas of natural or semi-natural habitats to nest and/or forage. Landscape structure has been shown to influence pollinator communities ...
Managing a Dynamic North Sea in the light of its ecological dynamics: Increasing occurrence of large baleen whales in the southern North Sea
(Elsevier Ltd, 2022-03-01)
A recent increase in sightings and strandings of humpback and to a lesser extent, fin whales in the southern North Sea has been well documented. This positive trend in the marine mammal community is to be welcome. A similar ...
Evaluation of the skill of length-based indicators to identify stock status and trends
(Oxford University Press, 2022-03-26)
In data-poor situations, length-based indicators (LBIs) and reference points based on life history parameters have been proposed to classify stocks according to conservation status and yield optimization. Given the variety ...
Biogeography in the deep: Hierarchical population genomic structure of two beaked whale species
(Elsevier B.V., 2022-10-14)
The deep sea is the largest ecosystem on Earth, yet little is known about the processes driving patterns of genetic diversity in its inhabitants. Here, we investigated the macro- and microevolutionary processes shaping ...
Addressing cohort uncertainty through advanced length frequency and stage-based assessment models with application to anglerfish
(Atlantic Technological University, 2022-02)
Fisheries stock assessments are important tools for successful management of fisheries. Reliability of a stock assessment model is often determined by the data available and accounting for key uncertainties in the data is ...
Unlocking the archive: using the biochemical and isotopic composition of fish scales to understand the marine phase of Atlantic salmon
(2022-04)
The Atlantic salmon is a species of great importance culturally, economically and ecologically. Recent declines suffered by many populations have been linked to marine mortality, therefore a better understanding of the ...
Dynamic gill and mucus microbiomes during a gill disease episode in farmed Atlantic salmon
(2022-10-06)
Amoebic gill disease (AGD) and complex gill disease (CGD) are recurrent gill disorders in Atlantic salmon, resulting in significant aquaculture losses. The role of gill microbiomes in gill disease development is unclear. ...
Dynamics and impacts of changing reference points with a focus on recruitment productivity
(Atlantic Technological University, 2022-10)
Managing fish stocks in the context of changing ecosystems and productivity is an ongoing challenge for fisheries science. Reference points are key tools for enabling effective management, defining management goals, guiding ...
