Phylogeny6
Ontogeny is the developmental history of an organism within its own lifetime, as distinct from phylogeny, which refers to the evolutionary history of a species. (wikipedia.org)
While developmental (i.e., ontogenetic) processes can influence subsequent evolutionary (e.g., phylogenetic) processes (see evolutionary developmental biology and recapitulation theory), individual organisms develop (ontogeny), while species evolve (phylogeny). (wikipedia.org)
He proposed that individual development followed developmental stages of previous generations and that the future generations would add something new to this process, and that there was a causal parallelism between an animal's ontogeny and phylogeny. (wikipedia.org)
In addition, Haeckel suggested a biogenetic law that ontogeny recapitulates phylogeny, based on the idea that the successive and progressive origin of new species was based on the same laws as the successive and progressive origin of new embryonic structures. (wikipedia.org)
Marine biologist Walter Garstang reversed Haeckel's relationship between ontogeny and phylogeny, stating that ontogeny creates phylogeny, not recapitulates it. (wikipedia.org)
The results of this analysis showed that the development of tree crown and reproduction were mainly controlled by annual shoot length and by variables related to branch topology (branching order, relative vigour) and ontogeny (tree age, ontogenic shoot age). (botany.one)
The results of this study may help to improve assessments of the future of these species in the context of climate change, particularly through better understanding of the interactions between exogenous (climate and site conditions) and endogenous factors (ontogeny, topology). (botany.one)
Pathways2
Thus, knowledge of the major signaling pathways governing this dual ontogeny in land plants is not only required for basic research but also for biotechnological applications to develop novel breeding methods accelerating trait development. (nih.gov)
Therefore, the aim of the present study was to analyze a wide range of genes involved in liver development, cell stress, lipid and carbohydrate metabolisms throughout embryogenesis in mule ducks to better understand the ontogeny of pathways related to liver fattening. (biomedcentral.com)
Closely related1
In combination, these findings confirm the efficacy of trabecular bone in reflecting locomotor ontogeny differences between closely related taxa. (mendeley.com)
Climate1
Our results underscore the importance of considering ontogeny and phenotypic plasticity in assessing the impacts of climate change, particularly for species adapted to spatially and temporally heterogeneous environments. (escholarship.org)
Stages4
Another way to think of ontogeny is that it is the process of an organism going through all of the developmental stages over its lifetime. (wikipedia.org)
Sexual dimorphism is predicted to be constrained by the underlying genetic architecture shared between the sexes and through ontogeny, but whole-transcriptome data for both sexes across genotypes and developmental stages are lacking. (biorxiv.org)
In addition, there is limited information on ontogeny of autotrophic stages. (scialert.net)
The purpose of the present work was to characterize a caleosin expressed in the olive anther over different key stages of pollen ontogeny, as a first approach to unravel its biological function in reproduction. (biomedcentral.com)
Species3
We investigate the cranial, mandibular, and dental ontogeny of the pacarana Dinomys branickii , the only extant species of the rodent family Dinomyidae. (bioone.org)
Some observed that craniomandibular trends in the ontogeny of D. branickii are reflected in the size of Ctenohystrica taxa, with small species of this lineage showing features similar to those of juveniles of D. branickii and large species resembling adults of the pacarana. (bioone.org)
Degree of anisotropy did not show statistical support for predicted species differences, but this may be due to sample size, as observed changes through ontogeny reflect expected trends in the capitate. (mendeley.com)

This approach will permit analysis of B cell clonal ontogeny, antibody diversity and lymphoma cell progression and heterogeneity. (lu.se)
Adults2
The LRV exhibited a mixed developmental mode: while series developed from juvenile precursors whose acoustic features gradually approached those of adults, individual notes appeared later in the ontogeny and de novo , with acoustic features undistinguishable from those of adults. (peerj.com)
In the four following sections we discuss landmarks which characterize biological rhythmicity in distinct moments of ontogeny: infants, adolescents, adults and elderly. (bvsalud.org)
Influences1
therefore, understanding the influences of ontogeny and phenotypic plasticity on tolerance to these critical environmental parameters is particularly important for Delta Smelt and other San Francisco Estuary fishes. (escholarship.org)
Temperature3
Egg incubation and yolk-sac larval development was performed in three laboratory tanks (of 35 l each) at temperature condition of 21°C. For the study of ontogeny, were sampled in the embryonic stage 25 eggs every 30 min and in yolk-sac larval stage, 10 specimens every 4 h. (scialert.net)

Despite an expanding body of literature focused on distal skin temperature, little information is available about the ontogeny and practically nothing about age-related changes in this rhythm. (org.es)
Investigate2
In the proposed project, we will investigate the structure and ontogeny of mastigont in Paratrimastix pyriformis (Metamonada), the model organism in our laboratory. (stars-natur.cz)
Although the ultrastructure of P. pyriformis and its relatives has been investigated for the past few decades, we want to go a step further and investigate the details of the process of cell division and ontogeny of this cytoskeleton. (stars-natur.cz)
Development5
Ontogeny (also ontogenesis) is the origination and development of an organism (both physical and psychological, e.g., moral development), usually from the time of fertilization of the egg to adult. (wikipedia.org)
The term ontogeny has also been used in cell biology to describe the development of various cell types within an organism. (wikipedia.org)
Ontogenetic changes in the postnatal ontogeny of the skull of D. branickii are mostly related to the development of the occlusal system and action of associated muscles. (bioone.org)
