The historical reconstruction of distribution of the genus Halecium (Hydrozoa: Haleciidae): a biological signal of ocean warming? [PDF]

open access: yes, 2017
The distribution of 130 nominal species of the genus Halecium, based on published records, has been mapped for the first time in a comprehensive set of marine ecoregions, to analyse their distribution.

Capitalizing on the wealth of chemical data in the accretionary structures of aquatic taxa: Opportunities from across the tree of life

open access: yesLimnology and Oceanography Letters, Volume 10, Issue 1, Page 18-36, February 2025.
Abstract Aquatic organisms are natural data loggers and record chemical variations within hardened accretionary structures like shells and teeth. Chemical sclerochronology is the study of these chemical variations through time and how they are used to understand environmental change and the physiology and ecology of species.

Harp Seals: Monitors of Change in Differing Ecosystems [PDF]

open access: yes, 2020
Harp seals are the most abundant marine mammal in the north Atlantic. As an ice obligatory predator, they reflect changes in their environment, particularly during a period of climatic change.

Atmospheric Pressure Rivalry Between the Arctic and Northern Pacific: Implications for Alaskan Climate Variability

open access: yesInternational Journal of Climatology, Volume 44, Issue 15, Page 5339-5357, 15 December 2024.
The recent phase of decadal mode of variability in the Pacific Arctic Region is dominated by the North Pacific Aleutian Low and is associated with the Pacification of the Arctic Ocean, with conditions favourable for regional warming, freshening, and expansion of Pacific species into the Arctic. ABSTRACT Located at the confluence of the Arctic and North

Age-dependent patterns of spatial autocorrelation in fish populations [PDF]

open access: yes, 2021
The degree of spatial autocorrelation in population fluctuations increases with dispersal and geographical covariation in the environment, and decreases with strength of density dependence.

A Machine Learning Approach to Produce a Continuous Solar‐Induced Chlorophyll Fluorescence Over the Arctic Ocean

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 1, Issue 4, December 2024.
Abstract Phytoplankton primary production is a crucial component of Arctic Ocean (AO) biogeochemistry, playing a pivotal role in carbon cycling by supporting higher trophic levels and removing atmospheric carbon dioxide. The advent of satellite observations measuring chlorophyll a concentration (Chl_a) has provided unprecedented insights into the ...

Key Uncertainties and Modeling Needs for Managing Living Marine Resources in the Future Arctic Ocean

open access: yesEarth's Future, Volume 12, Issue 8, August 2024.
Abstract Emerging fishing activity due to melting ice and poleward species distribution shifts in the rapidly‐warming Arctic Ocean challenges transboundary management and requires proactive governance. A 2021 moratorium on commercial fishing in the Arctic high seas provides a 16‐year runway for improved scientific understanding.

Kelp forest diversity under projected end‐of‐century climate change

open access: yesDiversity and Distributions, Volume 30, Issue 6, June 2024.
Abstract Aim Future climate change threatens marine forests across the world, potentially disrupting ecosystem function and services. Nonetheless, the direction and intensity of climate‐induced changes in kelp forest biodiversity remain unknown, precluding well‐informed conservation and management practices. Location Global.

Space‐use strategies drive diet composition of Baffin Bay polar bears

open access: yesEcosphere, Volume 15, Issue 4, April 2024.
Abstract Polar bears (Ursus maritimus) depend on sea ice to hunt their ice‐associated prey. However, climate‐induced sea ice loss is leading to changes in space‐use strategies of polar bears, with bears in some subpopulations spending more time on land or selecting alternative habitats.
