Features of growth and generative development of Campsis radicans (L.) Seem. ex Bureau in the conditions of the Northern Black Sea region

open access: yesНаукові доповіді Національного університету біоресурсів і природокористування України
The need to control the spread of introduced species with high adaptive potential in new ecological conditions necessitates the study of their biological properties. The aim of the study was to establish the biological characteristics of Campsis radicans

Born this way: Does variation in perinatal limb bone morphology predict adult locomotor repertoire in primates?

open access: yesThe Anatomical Record, EarlyView.
Abstract Primates show a high degree of locomotor diversity that engenders similar variance in limb bone cross‐sectional geometry and bending strength: leaping primates have stronger hindlimb bones whereas suspensory species have stronger forelimb bones.

Exploring the cranial morphology and possible convergences of Triassic non‐crocodylomorph pseudosuchians (Archosauria: Pseudosuchia) with other sauropsids through linear morphometrics

open access: yesThe Anatomical Record, EarlyView.
Abstract Triassic pseudosuchians had highly diversified cranial morphologies. These archosaurs occupied diverse ecological roles, ranging from terrestrial predators and herbivores to semiaquatic ambush predators and possible waders. Here, we apply linear cranial morphometrics to assess possible convergences with other sauropsids from the clades ...

Ontogenesis

open access: yes, 2017
Every organism undergoes some form of ontogenetic development, which represents the changes in size, shape, physiology, maturity status or behavior that occur during the organism's lifetime. In natural populations, ontogenetic development of organisms leads to differences in the way the organisms interact with their environment.

Developmental morphology of claspers and clasper‐glands during maturation in Potamotrygon wallacei (Chondrichthyes: Potamotrygoninae)

open access: yesThe Anatomical Record, EarlyView.
Abstract The claspers are the copulatory organs in male elasmobranchs, responsible for directing the semen into the female cloaca (C). However, the microscopic morphology of the claspers remains poorly understood. This study describes the morphology of the claspers and clasper glands (CGs) of cururu stingray (Potamotrygon wallacei) at different ...

Postcranial anatomy and osteohistology of an early prozostrodont cynodont from the Upper Triassic of Brazil

open access: yesThe Anatomical Record, EarlyView.
Abstract Prozostrodon brasiliensis, a probainognathian cynodont of the clade Prozostrodontia, is recognized as a key taxon for understanding the origin of Mammaliaformes and mammals. Despite detailed investigations of its cranial anatomy, the postcranial skeleton has received comparatively less attention.

Lypoxigenase activity of Salvinia natans (L.) All. in ontogenesis

open access: yes, 2016
Уперше ідентифіковано і досліджено характер змін активності ліпоксигенази (ЛОГ) та вміст розчинних білків в органах однорічної різноспорової водної папороті Salvinia natans (L.) All. в онтогенезі.

Developmental differences in cortical bone structure in chimpanzee and human femora reflect early locomotor independence in humans

open access: yesThe Anatomical Record, EarlyView.
Abstract The cortical bone structure of long bone diaphyses changes throughout growth via skeletal modeling and has important implications for bone strength and structural integrity. Ontogenetic trends in diaphyseal structure have been identified in both chimpanzees and humans but it is not yet clear how these trends compare given notable differences ...

REGULARITIES OF EARLY POSTNATAL ONTOGENESIS AMONG BATS (SUBORDER MICROCHIROPTERA)

open access: yes, 1996
The aim is to determine the factors leading to the divergence of the patterns in the postnatal ontogenesis of bats and to reveal the regularities in the growth and age transformation of the constitution, motor activity and orientation of the cubs.
