Effects of Ontogeny on δ13C of Plant- and Soil-Respired CO2 and on Respiratory Carbon Fractionation in C3 Herbaceous Species. [PDF]

open access: yesPLoS ONE, 2016
Knowledge gaps regarding potential ontogeny and plant species identity effects on carbon isotope fractionation might lead to misinterpretations of carbon isotope composition (δ13C) of respired CO2, a widely-used integrator of environmental conditions. In

Early Pictures in Ontogeny

open access: yes, 2009
There is a strong tradition behind distinguishing between the concrete or material qualities of a sign, and its meaning or ideal qualities. And this applies to pictures too. It seems that it was not until Modernist art and design came along that this distinction started to become critical.

Ontogeny in the steinmanellines (Bivalvia: Trigoniida): an intra- and interspecific appraisal using the Early Cretaceous faunas from the Neuquén Basin as a case study

open access: yes, 2022
Despite the paleontological relevance and paleobiological interest of trigoniid bivalves, our knowledge of their ontogeny - an aspect of crucial evolutionary importance - remains limited.

Extraordinary morphological changes in valve morphology during the ontogeny of several species of the Australian ostracod genus Bennelongia (Crustacea, Ostracoda) [PDF]

open access: yes, 2013
Ostracods belonging to the genus Bennelongia differ much in valve morphology between adults and juveniles. Adult valves are asymmetrical, characterised by a beak-like feature in the anteroventral region of the left valve, and, with some notable ...

A Foxo1-Klf2-S1pr1-Gnai1-Rac1 signaling axis is a critical mediator of Ostm1 regulatory network in T lymphopoiesis

open access: yesiScience, 2022
Summary: Ostm1 mutations cause the severe form of osteopetrosis with bone marrow deficiency in humans and mice, yet a role in T cell ontogeny remains to be determined.

Involvement of the hypothalamic-pituitary-thyroid axis and its interaction with the hypothalamic-pituitary-adrenal axis in the ontogeny of avian thermoregulation: a review

open access: yes, 2008
The emergence of thermoregulation in avian species is a complex matter in which neural as well as hormonal processes are involved. In a previous paper, the neural aspects of primary avian thermoregulation were discussed.

Larval development of the Mexican Snook, Centropomus poeyi (Teleostei: Centropomidae)

open access: yesNeotropical Ichthyology, 2018
We document for the first time the early ontogeny of Centropomus poeyi based on captive raised material representing 0-19 days posthatch (dph). The achievement of early developmental landmarks (i.e., yolk-sac depletion, flexion, development of fins) and ...

Developing Self-Awareness in Children during Early Ontogenesis

open access: yesСибСкрипт
Basic elements of self-awareness emerge and progress differently in different children. These timing peculiarities remain understudied in preschoolers. A comprehensive review revealed no clear guidelines, procedures, or technologies for psychological and

Expression and localization of Aquaporin 1a in the sea-bass (Dicentrarchus labrax) during ontogeny

open access: yes, 2011
The successful establishment of a species in a given habitat depends on the ability of each of its developing stages to adapt to the environment. In order to understand this process we have studied the adaptation of a euryhaline fish, the sea-bass ...

Peptidylarginine deiminase and deiminated proteins are detected throughout early halibut ontogeny - Complement components C3 and C4 are post-translationally deiminated in halibut (Hippoglossus hippoglossus L.) [PDF]

open access: yes, 2019
Post-translational protein deimination is mediated by peptidylarginine deiminases (PADs), which are calcium dependent enzymes conserved throughout phylogeny with physiological and pathophysiological roles. Protein deimination occurs via the conversion of
