But how does it smell? An investigation of olfactory bulb size among living and fossil primates and other euarchontoglirans

open access: yesThe Anatomical Record, EarlyView.
Analysis of cranial endocast data of 181 extant and 41 fossil species from Euarchontoglires shows that there was a reduction in olfactory bulb size in Crown Primates, but that there were also subsequent reductions in various other primate clades (Anthropoidea, Catarrhini, Platyrrhini, crown Cercopithecoidea, Hominoidea).

Inside the head of Crotalus durissus LINNAEUS, 1758 (Serpentes, Viperidae, Crotalinae): Macroscopic description of the brain with ontogenetic insights

open access: yesThe Anatomical Record, EarlyView.
Abstract Neuroanatomy studies in vertebrates have garnered significant attention in recent years, particularly driven by advancements in computerized tomography imaging techniques. Nonetheless, these advancements remain largely constrained to specific vertebrate groups, notably mammals, birds, and fish, leaving studies in reptiles at an incipient stage.

Silesaurid (Archosauria: Dinosauriformes) remains from the base of the Dockum Group (Late Triassic: Otischalkian) of Texas provide new insights to the North American record of dinosauriforms

open access: yesThe Anatomical Record, EarlyView.
Abstract Silesaurids (Archosauria: Dinosauriformes) are found in Middle to Upper Triassic deposits across Pangea, but few stratigraphic sections record the evolution of the group in one geographic area over millions of years. Here, we describe silesaurid remains from the oldest of the Upper Triassic stratigraphic sequence from the base of the Dockum ...

Discovery of sexual dimorphism of the laryngeal sac in the common minke whale Balaenoptera acutorostrata

open access: yesThe Anatomical Record, EarlyView.
Abstract Mysticetes, or baleen whales, have an air sac on the ventral surface of the larynx known as the “laryngeal sac.” The primary hypothesis regarding this structure's function is that it is involved in sound production. However, several other functions have been proposed, including air recycling, air storage, and even buoyancy control.

First Nations Aboriginal Ring Trees in New South Wales—Establishing a Cultural Context and Basic Archaeological Recording Typology

open access: yesArchaeology in Oceania, EarlyView.
ABSTRACT This paper examines ring trees—a type of culturally modified tree, intentionally created by Australian First Nations Aboriginal peoples by manipulating tree growth to form permanent loops (rings) within the structure. Historically, this site type has been underrepresented and underappreciated by academics and archaeologists.

Energy efficient alternatives to decarbonize the pulp and paper industry – the case of linerboard production

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Variability in fossil fuel prices and a commitment to reducing greenhouse gas (GHG) emissions have driven the US pulp and paper (P&P) industry to adopt technologies that decrease reliance on fossil fuels. In this regard, enhancing energy efficiency is crucial to the decarbonization of the sector.

Prescription drug use in breastfeeding mothers and infant exposure: A register‐based cohort study

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Abstract Aims Breast milk is the optimal infant nutrition; however, many infants may be exposed to prescription drugs if used by their mothers during breastfeeding. The aim of this study was to evaluate the prevalence and patterns of prescription drug use among breastfeeding mothers and to assess the availability of relative infant dose information for
