Coccolithophore biodiversity controls carbonate export in the Southern Ocean [PDF]

open access: yes, 2020
Southern Ocean waters are projected to undergo profound changes in their physical and chemical properties in the coming decades. Coccolithophore blooms in the Southern Ocean are thought to account for a major fraction of the global marine calcium ...

Breaking Symmetry: Fluctuating Asymmetry and Geometric Morphometrics as Tools for Evaluating Developmental Instability under Diverse Agroecosystems

open access: yesSymmetry, 2020
Fluctuating asymmetry (FA), in contrast with other asymmetries, is the bilateral asymmetry that represents small, random developmental differences between right and left sides.

Differentiation of Trichuris species using a morphometric approach [PDF]

open access: yes, 2019
Trichuris trichiura is a nematode considered as the whipworm present in humans and primates. The systematics of the genus Trichuris is complex. Morphological studies of Trichuris isolated from primates and humans conclude that the species infecting these

Translational genetic modelling of 3D craniofacial dysmorphology: elaborating the facial phenotype of neurodevelopmental disorders through the prism of schizophrenia [PDF]

open access: yes, 2017
Purpose of Review: In the context of human developmental conditions, we review the conceptualisation of schizophrenia as a neurodevelopmental disorder, the status of craniofacial dysmorphology as a clinically accessible index of brain ...

Natural history notes on worker size, colony size, and nest structure of Azteca muelleri Emery, 1893 (Hymenoptera: Formicidae) in Cecropia glaziovii (Rosales: Urticaceae) from the Atlantic Forest

open access: yesEntomological Communications, 2021
Mutualistic association between Azteca Forel, 1878 ants and Cecropia Loefl. plants are one of the most studied interactions in Neotropics, however, natural history studies of Azteca species still poorly investigated due to the great effort required to ...

Do cladistic and morphometric data capture common patterns of morphological disparity? [PDF]

open access: yes, 2015
The distinctly non-random diversity of organismal form manifests itself in discrete clusters of taxa that share a common body plan. As a result, analyses of disparity require a scalable comparative framework.

Computational Screening of Tip and Stalk Cell Behavior Proposes a Role for Apelin Signaling in Sprout Progression [PDF]

open access: yes, 2016
Angiogenesis involves the formation of new blood vessels by sprouting or splitting of existing blood vessels. During sprouting, a highly motile type of endothelial cell, called the tip cell, migrates from the blood vessels followed by stalk cells, an ...

Size, shape, and form: concepts of allometry in geometric morphometrics

open access: yesDevelopment, Genes and Evolution, 2016
Allometry refers to the size-related changes of morphological traits and remains an essential concept for the study of evolution and development.

Morphometric Traits, Serum Chemistry and Antibody Response of Three Chicken Genotypes under Free-Range, Semi-Intensive and Intensive Housing Systems

open access: yesBrazilian Journal of Poultry Science, 2019
The present study evaluated the effect of housing system on the morphometrics, serum chemistry and antibody response of dual-purpose chicken genotypes. A total of 156 pullets and 39 cockerels were randomly picked from 18 treatment block groups (3 housing
