Functional morphology of the pharyngeal teeth of the ocean sunfish, Mola mola

open access: yesThe Anatomical Record, EarlyView.
Abstract Many fish use a set of pharyngeal jaws in their throat to aid in prey capture and processing, particularly of large or complex prey. In this study—combining dissection, CT scanning, histology, and performance testing—we demonstrate a novel use of pharyngeal teeth in the ocean sunfish (Mola mola), a species for which pharyngeal jaw anatomy had ...

ONTOGENESIS OF UROLITES

open access: yes, 2015
During the ontogenesis of urolites the depth zone mineral substance undergoes phase transformations and morphological changes. The restoration of dissolution surfaces with the mineral phase exchange, new growth rhythms generation, globular particles ...

Nymphal and adult cephalic chaetotaxy of the Cydnidae (Hemiptera: Heteroptera), and its adaptive, taxonomic and phylogenetic significance

open access: yesEuropean Journal of Entomology, 2002
Cephalic chaetotaxy of nymphal and adult stages of species from all the subfamilies of Cydnidae s. str. (sensu Froeschner, 1960 and Lis, 1994), namely Garsauriinae, Cephalocteinae, Cydninae, Sehirinae, and Amnestinae, was studied.

Taste sensations: history of study, evolutionary feasibility and strategies for forming correct taste preferences in children

open access: yesМедицинский совет, 2020
Taste preferences influence not only the formation of human health, but also many areas of his life. That is why the problem of understanding the nature and regularities of taste formation has been a concern for scientists since ancient times and remains

Tooth eruption status and bite force determine dental microwear texture gradients in albino rats (Rattus norvegicus forma domestica)

open access: yesThe Anatomical Record, EarlyView.
Abstract Dental microwear texture analysis (DMTA) is widely applied for inferring diet in vertebrates. Besides diet and ingesta properties, factors like wear stage and bite force may affect microwear formation, potentially leading to tooth position‐specific microwear patterns.

The morphology of the oval window in Paranthropus robustus compared to humans and other modern primates

open access: yesThe Anatomical Record, EarlyView.
Abstract The oval window (OW) is an opening connecting the inner and middle ear. Its area has been shown to consistently scale with body mass (BM) in primates, and has been used alongside semi‐circular canal (SCC) size to differentiate Homo sapiens and fossil hominins, including Paranthropus robustus.

Ontogenesis and biological peculiarities of Nymphaea gigantea hook.

open access: yes, 1999
The periods of ontogenesis of Nymphaea gigantea Hook, in the greenhouse conditions at O.V. Fomin Botanical Gardens have been studied. The latent period lasts for 8 to 9 months; pregenerative (virginile) – 3 to 4 years; repoductive (generative) – 2 to 3 ...

A perspective from the Mesozoic: Evolutionary changes of the mammalian skull and their influence on feeding efficiency and high‐frequency hearing

open access: yesThe Anatomical Record, EarlyView.
Abstract The complex evolutionary history behind modern mammalian chewing performance and hearing function is a result of several changes in the entire skeletomuscular system of the skull and lower jaw. Lately, exciting multifunctional 3D analytical methods and kinematic simulations of feeding functions in both modern and fossil mammals and their ...

Dialectical inferences in the ontogenesis of social representations [PDF]

open access: yes, 2016
This article deals with a possible collaboration between two disciplines: developmental psychology and the theory of Social Representations (SR). The latter takes the study of the ontogenesis of social representations as a central issue, even though the ...
