A New Experimental Protocol for Assessing Hominoid Assisted Arboreal Bipedalism. [PDF]

Am J Biol Anthropol
A new experimental protocol for investigating arboreal bipedalism in hominoids was successfully used by all available age and sex classes of chimpanzees in the case study. This protocol identifies two forms of arboreal bipedalism: forward facing and sideways, and allows for the collection of gait parameter data for future comparative studies.

Exploring Larval Axolotl Brain Development: Insights Into Developmental and Functional Constraints. [PDF]

Evol Dev
We studied brain shape and volume variations during larval development of the Mexican axolotl. Modularity, morphological integration, and allometric regressions supported both mosaic and concerted evolution models, highlighting a complex interplay of constraints during axolotl ontogeny.

Morphometric study of the bony labyrinth of the inner ear in the European moles Talpa europaea, Talpa occidentalis, and Talpa aquitania. [PDF]

J Anat
The study investigates the shape of the semicircular canals in the inner ear of three sister mole species—Talpa europaea, Talpa aquitania, and Talpa occidentalis—using geometric morphometrics on 58 specimens. It finds both interspecific and intraspecific variability in canal morphology, but no evidence of sexual dimorphism.

Anatomy in Cuvier's Paris: Broadening participation through an international research program for historically minoritized undergraduates. [PDF]

Anat Sci Educ
Abstract Most research programs recruit students with high grades, previous lab experience, and strong supervisor recommendations. However, these requirements can bar students from historically marginalized backgrounds from gaining these kinds of valuable experiences, thus contributing to the well documented limited diversity in science, technology ...

Early Biogeography of Otophysi Points to the Neotropics as the Cradle of Characiphysan Fishes. [PDF]

Ecol Evol
Otophysan fishes represent 70% of living freshwater fishes with 12,000 species. Relationships among their four orders were explored through a dense taxonomic sampling including 529 complete mitochondrial genomes and 4 nuclear genes for 324 species.

Accommodation of Dental Variations During Jaw Growth in Ungulate Mammals. [PDF]

J Exp Zool B Mol Dev Evol
Using geometric morphometrics, we compared the covariation pattern of the dentition and the palate during growth in 23 ungulate species. ABSTRACT The growth of teeth and jaw bones is intimately linked in vertebrates, especially in mammals due to their specialized dentition and limited body growth.

Modelling marsupial mastication: The biomechanical bite model of the Linnaeus's mouse opossum Marmosa murina (Marsupialia, Didelphidae). [PDF]

J Anat
The marsupial masticatory apparatus has rarely been studied until recently, mainly in Australasian species. We therefore reconstructed the maximum bite forces of the South American Linnaeus's mouse opossum Marmosa murina using in vivo bites, specimen dissections, and 3D static equilibrium of the jaw muscles.

Rectoprotomarssonella n. gen., a new agglutinated foraminiferal genus from the Upper Cretaceous of the Carpathian Flysch [PDF]

, 2007
The new agglutinated foraminiferal genus Rectoprotomarssonella n. gen. is characterized by its high trochospiral coiling with multiserial to uniserial chamber arrangement and solid, noncanaliculate wall with calcareous cement.

What Is the Acheulean? [PDF]

Evol Anthropol
ABSTRACT The Acheulean represents the longest cultural period known to human history, lasting globally for more than 1.75 million years. It may have emerged as early as 1.95 Ma in Africa, spreading throughout much of the continent and then into Eurasia and lasting up to 350–200 ka in western Europe and South Asia, and even later in eastern Asia ...
