Fish welfare in a changing world: New developments and current challenges

open access: yesJournal of Fish Biology, EarlyView.
Abstract The welfare of non‐human animals is central to ethical discussions on animal use, with increasing attention to fish welfare across research, aquaria, aquaculture, and fisheries. This paper reviews current theoretical approaches to animal welfare and recent advances in defining and assessing fish welfare since the seminal paper by Huntingford ...

Distribution and ecology of the four Macrourus species by‐caught in the longline fishery at South Georgia, Southern Ocean

open access: yesJournal of Fish Biology, EarlyView.
Abstract Although Macrourus species are the main by‐catch across Southern Ocean longline fisheries, including around South Georgia, the lack of species‐specific data has hindered effective management and ecological understanding. Aggregation of macrourids at genus level masks critical interspecific differences in life‐history strategies and ...

Contrasting population genetic structures of congeneric coastal flounders associated with different early life histories

open access: yesJournal of Fish Biology, EarlyView.
Abstract Marine fish species are likely to exhibit little genetic differentiation among populations due to their high dispersal potential during early life stages and migratory nature. However, recent studies have increasingly reported intraspecific genetic differentiation resulting from species‐specific ecological traits, environmental factors, and ...

Hoffmann's two‐toed sloth II: Muscle architectural properties in the thoracic limb of Choloepus (Pilosa: Xenarthra)

open access: yesJournal of Anatomy, EarlyView.
Two‐toed sloths use their thoracic limbs for more frequent and greater suspensory support than three‐toed sloths and have muscle architectural properties consistent with stability of the pectoral girdle, enhanced flexor force/torque applied at the shoulder and elbow joints, and grip on the support as indicated by their myology. Abstract Two‐toed sloths

Scratching beneath the surface: Quantification of muscle architecture and myosin heavy chain content in the forelimbs of black‐tailed prairie dogs (Cynomys, Rodentia)

open access: yesJournal of Anatomy, EarlyView.
Black‐tailed prairie dogs are highly social ground squirrels that excavate communal burrow systems, most often in medium‐textured soils. Their forelimbs demonstrate morphofunctional trade‐offs for scratch‐digging and terrestrial ecology, including well‐developed and fast‐contracting proximal musculature with large mechanical advantage paired with ...

Biodiversity Finance: A Systematic Review and Interpretative Framework for an Emerging Research Frontier

open access: yesJournal of Economic Surveys, EarlyView.
ABSTRACT The accelerating loss of biodiversity and ecosystem degradation are increasingly recognized as economically material phenomena with implications for financial markets and financial stability. Yet biodiversity finance remains fragmented across environmental economics, sustainable finance, corporate disclosure, risk management, and conservation ...
