Learning to remember: The early ontogeny of episodic memory [PDF]

open access: yesDevelopmental Cognitive Neuroscience, 2014
Over the past 60 years the neural correlates of human episodic memory have been the focus of intense neuroscientific scrutiny. By contrast, neuroscience has paid substantially less attention to understanding the emergence of this neurocognitive system ...

Prenatal hypoxia alters the early ontogeny of dopamine neurons [PDF]

open access: yesTranslational Psychiatry, 2022
Dopaminergic (DA) dysfunction is a significant feature in the pathophysiology of schizophrenia. Established developmental risk factors for schizophrenia such as maternal immune activation (MIA) or developmental vitamin D (DVD) deficiency, when modelled ...

Early Ontogeny of Cichlids Using Selected Species as Examples [PDF]

open access: yesAnimals
The purpose of this study was to characterize in detail the reproductive strategy, course of embryogenesis, and development of larvae in three species of fishes of the genus Cichlasoma: the green terror (Andinoacara rivulatus), the red discus ...

Postcranial osteology of the first early-stage juvenile skeleton of Plateosaurus trossingensis from the Norian of Frick, Switzerland [PDF]

open access: yesActa Palaeontologica Polonica, 2020
Owing to monospecific mass-accumulation sites in Central Europe, the early-branching sauropodomorph Plateosaurus has one of the best fossil records among dinosaurs. Despite this, early-stage juveniles have been conspicuously absent.

Deciphering the morphological variation and its ontogenetic dynamics in the Late Devonian conodont Icriodus alternatus [PDF]

open access: yesFossil Record, 2022
Identification of relevant taxonomic and evolutionary units is a recurrent issue in the fossil record, and all the more for ancient fossils devoid of modern equivalents such as conodonts. Extensive morphological variation has often led to the description

Early ontogeny of tetra Markiana nigripinnis (Characiformes: Characidae) [PDF]

open access: yesNeotropical Ichthyology, 2023
The early development of Markiana nigripinnis is described by morphological characters, pigmentation, and morphometry. Larvae were obtained through semi-natural breeding, collected, fixed, and identified according to their development. Eighty individuals

Year-Round Spawning, Filial Cannibalism, and Embryonic and Larval Development of the Coral Reef Fish Orchid Dottyback, Pseudochromis fridmani

open access: yesFishes, 2023
Aquaculture of marine ornamental fish could potentially reduce the fishing pressure on wild stocks by the global aquarium trade, but its expansion is often constrained by the limited understanding on the biology and early life history of candidate ...

Effects of praziquantel on common carp embryos and larvae

open access: yesScientific Reports, 2022
This study aimed to assess the toxicity of praziquantel (anthelmintic drug) in different developmental stages of common carp (Cyprinus carpio) based on mortality, early ontogeny, growth, oxidative stress, antioxidant enzymes, histology and behaviour ...

Skeletal ontogeny of the caudal complex in Caspian kutum, Rutilus kutum (Kamensky, 1901) (Teleostei: Cyprinidae) during early development [PDF]

open access: yesCaspian Journal of Environmental Sciences, 2019
Study of skeletal ontogeny during early development is crucial in a successful larviculture. In this study, ontogeny of the caudal complex skeleton in Caspian kutum, Rutilus kutum, was studied from hatching up to 50-day post hatching (dph).

Early development and growth of sterlet (Acipenser ruthenus) in the Czech Republic

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2011
Growth rate of sterlet larvae and juveniles during 2008 and 2009 was studied under experimental and farming conditions in the Czech Republic. The embryos hatched when reaching a mean total length (TL) of 9.0 mm.
