Abstract Amphisbaenians (Squamata: Amphisbaenidae) are fossorial reptiles with highly specialized cranial morphology, yet their fossil record is frequently limited by fragmentary preservation. This study provides a detailed osteological redescription of the skulls of Amphisbaena braestrupi and Amphisbaena laurenti from the Pleistocene of Lagoa Santa ...

Assessment of intraspecific skull variation in the Campanian baenid turtle Plesiobaena antiqua
Abstract Baenids are freshwater paracryptodiran turtles with a fossil record ranging from the Early Cretaceous to the Eocene. The baenid Plesiobaena antiqua is the most common turtle in the Campanian (Late Cretaceous) Dinosaur Park Formation in Canada, but the apparent intraspecific variation remains poorly understood.

Circadian regulation of sleep during ontogenesis in humans [PDF]
The circadian system has evolved as an adaptation to periodically changing conditions on Earth. In mammals, and therefore in humans, the circadian system consists of the central and perip- heral oscillators generating a circadian rhythm.

Abstract This study, alongside prior work on crab‐eating macaques with O'Higgins, investigates regional variation in skull sexual dimorphism across different species of Old World monkeys. Findings reveal consistent patterns: the posterior skull regions (mandibular vertical ramus, chondrocranium and, possibly, the cranial vault) exhibit lower dimorphism,

Animal empathy reconsidered: a multidimensional profile account
ABSTRACT Empathy is the glue that holds societies together and yet several fundamental questions about empathy persist. What is empathy (the definitional question)? Is it uniquely human and, if not, which nonhuman animals possess empathy (the distribution question)? Which type or quality of empathy is realized in different species (the quality question)

Food‐solicitation displays in nestling birds: still begging for answers
ABSTRACT Nestling begging is a key model for understanding animal communication and parent–offspring conflict. Dynamic begging displays are often interpreted as costly, honest signals of need, with honesty maintained by viability costs, as proposed in Godfray's influential signalling model.

Circulating monocyte partitioning and its alteration in hematological chronic neoplasms
Abstract Circulating monocyte partitioning refers to the relative quantification of the three main monocyte subsets in the peripheral blood, namely classical (cMo), intermediate (iMo), and non‐classical (ncMo) monocytes, as assessed by flow cytometry, a new nomenclature described 15 years ago.
