Broadening the semiaquatic scene: Quantification of long bone microanatomy across pinnipeds

The Anatomical Record, EarlyView.
Abstract Investigations of bone microanatomy are commonly used to explore lifestyle strategies in vertebrates. While distinct microanatomical limb bone features have been established for exclusively aquatic and terrestrial lifestyles, identifying clear patterns for the semiaquatic lifestyle remains more challenging.

Defining plant ecological specialists and generalists: Building a framework for identification and classification

Ecology and Evolution, 2022
Specialization is a widespread but highly ambiguous and context‐dependent ecological concept. This quality makes comparisons across related studies difficult and makes associated terms such as “specialist” and “generalist” scientifically obscure.

Herbivore induction of the glucosinolate-myrosinase defense system: major trends, biochemical bases and ecological significance [PDF]

, 2009
Like many other plant defense compounds, glucosinolates are present constitutively in plant tissues, but are also induced to higher levels by herbivore attack.

Origin, evolution and biogeographic dynamics of the European rabbit (Oryctolagus cuniculus) in Southwestern Europe

The Anatomical Record, EarlyView.
Abstract The Pleistocene is a key period for understanding the evolutionary history and palaeobiogeography of the European rabbit (Oryctolagus cuniculus). The species was first documented in southeastern Iberia at the beginning of the Middle Pleistocene and appears to have rapidly spread throughout Southwestern Europe, where it was found in numerous ...

Antagonistic Structural Patterns in Complex Networks [PDF]

, 2018
Identifying and explaining the structure of complex networks at different scales has become an important problem across disciplines. At the mesoscale, modular architecture has attracted most of the attention.

Functional anatomy, jaw mechanisms, and feeding behavior of Dunkleosteus terrelli (Placodermi, Arthrodira)

The Anatomical Record, EarlyView.
A new musculoskeletal reconstruction and revision of the cranio‐mandibular anatomy of the Devonian arthrodire placoderm Dunkleosteus terrelli from a comparative and functional anatomical perspective. Dunkleosteus is a specialized arthrodire with many specializations for feeding on large vertebrates, and many of its features are part of broader ...

Histology and fossil diagenesis of a pterosaur tooth from the Crato Formation (Lower Cretaceous of Brazil)

The Anatomical Record, EarlyView.
Abstract Pterosaur dental biology remains poorly understood despite its importance for comprehending feeding strategies and flight adaptations. Here, we present the first comprehensive histological analysis of an ornithocheiriform pterosaur tooth from the Lower Cretaceous Crato Formation (Santana Group, Northeast Brazil).

Inter‐ and intraspecific variation in theropod dinosaur dental microwear and its palaeoecological implications

The Anatomical Record, EarlyView.
Abstract Differences in skull and tooth morphology, stomach contents, and estimated bite force between medium‐to‐large sized (≥100 kg) predatory theropod dinosaurs have long been suspected to correlate with differences in their diets and dietary guilds (e.g., hypercarnivory, piscivory).

Zooarchaeological Analysis of an Atoll Assemblage From Central Micronesia

Archaeology in Oceania, EarlyView.
ABSTRACT There has been a dearth of archaeological research on atolls in the central‐eastern Caroline Islands of Micronesia. This has limited our understanding of pre‐contact subsistence and settlement strategies in these more marginal and remote environments, particularly in regards to zooarchaeological data.

Career choices of the first seven cohorts of JCU MBBS graduates: producing generalists for regional, rural and remote northern Australia

Rural and Remote Health
Introduction: Generalism in the health workforce has been established as an important strategy to address health workforce maldistribution. Thus, to best serve the medical needs of northern Australia, the James Cook University (JCU) College of Medicine ...
