Developal/ontogenetic hypothesis
WebOntogenetic niche shift (abbreviated ONS) is an ecological phenomenon where an organism (usually an animal) changes its diet or habitat during its ontogeny (development). During the ontogenetic niche shifting an ecological niche of an individual changes its breadth and position.

We are interested if developmental stability predicts cognitive performance independent of age and lifestyle (e.g., diet and exercise).

(1) Ontogenetic hypothesis of the alternative segmentation pathways of a polymorphic species across several postembryonic stages (s0–sn) or instars.Different morphological conditions (morphs, m), here based exclusively on the segmental pattern, are indicated as mX Y, where X is the number of thoracic segments …
WebThe ontogenetic hypothesis for pachycephalosaurs proposes that: most of the unique skull structures found within the pachycephalosaur clade represent different life stages of the same species. Ontogeny is the study of: the physical change in a member of a particular species from birth to maturity. WebThis paper will present evidence to support ontogenetic and phylogenetic parallels and draw from these comparisons to further illuminate our understanding of micro and macro human development. Individual and collective stages of physical, psychological and spiritual development will be compared and their homologous structures examined.
WebThe hypothesis of retarded development is a classic and controversial issue in human evolution. It depends directly on the understanding of ontogenetic trajectories and their … WebThe ontogeny of behaviour is a subject which arouses considerable interest, perhaps because of the seeming contrast between humans and other animals in how behavioral skills are acquired. Whereas humans extensively adjust their behaviour based on experience (that is, through the process of learning ), the behaviour of many animal …
WebThe European hake, M. merluccius (Linnaeus 1758), is a benthopelagic predator, widely distributed in the entire Mediterranean Sea and in the northeastern Atlantic Ocean, with a high commercial value and a fundamental role in the trophic ecology of mesopelagic communities.

WebThis hypothesis is based on prior knowledge of plant development, whereby the seedling stage is a more vulnerable stage of the plant’s life cycle . Due to the plasticity of offspring in response to their current environment as they develop, transgenerational effects would be expected to be strongest during early life than later in ontogeny. ray griff promo 45WebAlthough adaptive divergence can occur without altering the basic developmental programme of the flower (ontogenetic scaling hypothesis), the rarity of reversion to … ray griffiths jewelry spnmar26WebOntogenetic Module corresponds to the defi-695 nition we gave in Section 3.3; no modifications were 696 needed.
