Effect of visual and electrosensory deterrents on captive elasmobranchs

Journal of Fish Biology, EarlyView.
Abstract Commercial gillnet fisheries interact with a wide range of elasmobranch species, many of which are incidentally captured as bycatch. Deterrent technologies have emerged as a potential approach for reducing interactions with threatened elasmobranchs.

Skeletons of swiftly swimming sharks: Three‐dimensional analysis of lamniform vertebral morphology and mineral architecture

Journal of Anatomy, EarlyView.
We examined morphology, 3D arrangement, and mineral amount in cartilaginous vertebrae from four lamniform shark families (Alopiidae, Carchariidae, Cetorhinidae, and Lamnidae). We identified family‐specific mineralization trends, and regional patterning of structures along the column.

Bone histological evidence for posture‐related load transmission in the talpid pectoral girdle

Journal of Anatomy, EarlyView.
Bone histology of the clavicle and scapula revealed distinct load‐bearing roles within the mammalian pectoral girdle associated with different forelimb postures. Hyper‐abducted moles exhibited an enhanced load‐bearing role of the clavicle, whereas the parasagittal shrew exhibited histological features consistent with the scapula acting as the principal

Reconstructing the major skull myology of the giant stem‐amphibian Mastodonsaurus: A case study for early tetrapods

Journal of Anatomy, EarlyView.
We reconstruct the major cranial musculature of the giant stem amphibian Mastodonsaurus giganteus, revealing a differentiated jaw‐adductor system, a probable sesamoid pulley, and previously unrecognised muscles. This EPB‐based case study establishes an anatomical framework for modelling feeding in early tetrapods and supports interpretations of ...

Contestation Between the State, Oil and Fishers in Trinidad and Tobago: (Re)producing ‘Edge’ Populations on the Post‐Plantation Extraction Frontier

Journal of Agrarian Change, EarlyView.
ABSTRACT Successive waves of extraction in the Caribbean—from plantation monocultures to oil and gas—have reshaped overlapping agrarian, coastal and marine environments, undermining the socio‐ecological foundations of small‐scale fisher livelihoods and generating ongoing conflict between the state, energy sector and fishing communities. Yet despite the

‘Let's Go to the Land Instead’: Indigenous Perspectives on Biodiversity and the Possibilities of Regenerative Capital

Journal of Management Studies, EarlyView.
Abstract The land has been a source of capital accumulation since colonization through extractive activities like mining and industrial agriculture. Indigenous peoples have profoundly different relationships with the land, which are more relational than extractive. However, their knowledge has been subjugated by and systematically excluded from Western

Contingent capital: A tale of two valuations

Journal of Risk and Insurance, EarlyView.
Abstract This study investigates the valuation gap between buyers and sellers of insurers' contingent capital, driven by asymmetric exposures to tax benefits, capital injections, and bankruptcy costs. We develop a novel Twin‐Tree Model with Jumps (TTMJ) that models the insurer's asset value dynamics by incorporating catastrophe risk, insolvency risk ...
