Pterodactylus scolopaciceps Meyer, 1860 (Pterosauria, Pterodactyloidea) from the Upper Jurassic of Bavaria, Germany:the problem of Cryptic Pterosaur Taxa in early ontogeny [PDF]

open access: yes, 2014
The taxonomy of the Late Jurassic pterodactyloid pterosaur Pterodactylus scolopaciceps Meyer, 1860 from the Solnhofen Limestone Formation of Bavaria, Germany is reviewed. Its nomenclatural history is long and complex, having been synonymised with both P.

Rethinking the ontogeny of mindreading [PDF]

open access: yes, 2006
We propose a mentalistic and nativist view of human early mental and social life and of the ontogeny of mindreading. We define the mental state of sharedness as the primitive, one-sided capability to take one's own mental states as mutually known to an ...

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.

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

Ontogeny of purinergic receptor-regulated Ca2+ signaling in mouse cortical collecting duct epithelium [PDF]

open access: yes, 2002
Changes in ATP-induced increase in {[}Ca2+], during collecting duct ontogeny were studied in primary monolayer cultures of mouse ureteric bud (UB) and cortical collecting duct (CCD) cells by Fura-PE3 fluorescence ratio imaging.

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.

Characterisation and ontogeny of natural killer cells in Xenopus laevis [PDF]

open access: yes, 2002
The initial aim of the work described in this Thesis was to investigate the lymphoid organ distribution, phenotype and function of the lymphocyte population identified by candidate anti-Xenopus natural killer (NK) cell monoclonal antibodies (mAb's ...
