Webing ontogenetic diet shifts, geographical variations on prey composition, and feed-ing habits. A total of 734 hake specimens ranging in size between 6 cm and 73 cm (Total Length, TL) were collected in 2024. In order to evaluate ontogenetic shifts in prey composition, samples were divided into five size classes and for each class the Webdiets shifts occur in fishes can help interpret temporal and ontogenetic shifts in habitat use, interactions with other fishes, and evaluate management scenarios for fishes and their prey resources. Our objective was to quantify the ontogenetic and seasonal diet shifts of smallmouth bass (Micropterus dolomieu) in Baron Fork Creek, Oklahoma.
WebOntogeny (also ontogenesis) is the origination and development of an organism (both physical and psychological, e.g., moral development), usually from the time of fertilization … WebTheory predicts far-reaching impacts of ontogenetic niche shifts regarding community structure and stabil-ity. Food web stability may be significantly reduced when accounting for ontogenetic diet shifts, because many (also seemingly generalist) species actually turn out to be ontogenetic specialists (Rudolf and Lafferty 2011).
