Histochemical indications for a chemically complex signal produced by the cervical gill slit gland of the pygmy sperm whale (Kogia breviceps)

The Anatomical Record, EarlyView.
Abstract The pygmy sperm whale (Kogia breviceps) possesses an exocrine gland associated with its false gill slit pigmentation pattern. The cervical gill slit gland is a compound tubuloalveolar gland that produces a holocrine secretion and displays maturational changes in size and secretory histology. While the morphology of the cervical gill slit gland

Morphology and function of pinniped necks: The long and short of it

The Anatomical Record, EarlyView.
Abstract Terrestrial vertebrates from at least 30 distinct lineages in both extinct and extant clades have returned to aquatic environments. With these transitions came numerous morphological adaptations to accommodate life in water. Relatively little attention has been paid to the cervical region when tracking this transition.

Topological and variational modularity: A case study using the pectoral girdle across the Chrosomus eos‐neogaeus hybridization complex

The Anatomical Record, EarlyView.
Abstract Modularity and integration are key developmental properties and have remained central in evo‐devo research because of how they relate to evolvability. While modularity and integration have commonly been assessed with landmark‐based geometric morphometrics (GMM), other methods such as anatomical network analysis (AnNA) are increasingly being ...

Snake and Moon ‘Right Way Marriage’ Stories on Stone and Bark

Archaeology in Oceania, EarlyView.
ABSTRACT In northwest Australia, boab trees hold significant cultural values for First Nations people. Their leaves, bark, roots and nuts are important as traditional resources for food, medicine, fibre, water and shade and serve as reference points in the landscape. Some of the tree trunks are inscribed with images and symbols which tell of events and
