WebOntogenetic behavior of Hudson River Atlantic sturgeon and Connecticut River shortnose sturgeon early life intervals were similar during laboratory observations. After hatching, free embryos were photonegative and sought cover. When embryos developed into larvae, fish left cover, were photopositive, and initiated downstream migration. Free embryos may … Web2 de abr. de 2016 · Behavioral sequences can vary considerably in the frequency and organization of behavioral categories (e.g. Malange et al. 2013).When there is within individual variability in behavioral patterns across ontogenetic stages, it may be related to allometric changes in body size (Japyassú and Ades 1998), to activational plasticity …
