Giants in the cold: Morphological evidence for vascular heat retention in the viscera but not the skeletal muscle of the basking shark (Cetorhinus maximus)

Journal of Fish Biology, EarlyView.
Abstract Fewer than 50 of the over 30,000 extant species of fishes have developed anatomical specializations facilitating endothermy in specific body regions. The plankton‐feeding basking shark (Cetorhinus maximus), traditionally classified as an ectotherm, was recently shown to have regionally endothermic traits such as centralized red muscle (RM ...

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.

Age and growth of the spiny butterfly ray Gymnura altavela (Elasmobranchii, Gymnuridae) in the Southwest Atlantic (in situ) and under human care in a public aquarium (ex situ): Plasticity and population patterns

Journal of Fish Biology, EarlyView.
Abstract This study provides the first age and growth assessment of the endangered spiny butterfly ray, Gymnura altavela (Linnaeus, 1758), in the Southwest Atlantic, while also updating the growth parameters (asymptotic disc width—DW∞ and growth coefficient—k) estimated in an ex situ a marine aquarium setting.

How Old Is a Turtle? Challenges in Interpreting Age Information in Sea Turtles

Ecologies
Marine turtles are iconic, globally distributed large reptiles with a largely oceanic life history that makes it difficult to characterize population demography and dynamics.

Modelling compressive loading in large‐bodied mammals reveals distinct biomechanical strategies in proboscidean humeri

Journal of Anatomy, EarlyView.
Graviportal proboscideans differ in limb morphology, adopting slender or more robust long bone morphotypes. Finite element analyses (FEA) on extant and extinct taxa reveal functional differences between morphotypes, with robust humeri exhibiting lower peak stress under neutral and off‐axis loading.

REPTILES FROM LATE CRETACEOUS COASTAL ENVIRONMENTS OF NORTHERN PATAGONIA

Publicación Electrónica de la Asociación Paleontológica Argentina, 2015
Toward the end of the Cretaceous the Atlantic Ocean covered parts of central-western Patagonia forming a wide archipelago. Remains of terrestrial and marine reptiles have been recorded in the Campanian and Maastrichtian of this area in rocks that ...

Mary Anning Rocks and its Outreach Impacts

Geoconservation Research
The Mary Anning Rocks charity started as a campaign to raise a statue for the noted early paleontologist and fossil collector Mary Anning in her hometown, Lyme Regis. Now, after the statue was raised, the campaign is still a vibrant and engaging example

Journal of Veterinary and Animal Sciences, 1998
Anisakid nematodes of the genera Porrocaecum, Contracaecum and Multicaecum are common parasites inhabiting the alimentary tract of reptiles, marine birds and mammals (Frey and Kutzer, 1982).

Cultivating diversity: is the functional diversity of nursery stocks sufficient for the establishment of functionally diverse restored woodlands?

Restoration Ecology, EarlyView.
Abstract Introduction Ecological restoration projects often rely on nurseries (NU) to provide plants to restore ecological communities. However, the range of species available in NU may not represent the range of ecological function found in species in reference (natural) communities.
