Life history traits are the things in an animal's life that affect life expectancy — critical issues like reproduction, growth, and survival.

life history traits of benthos at the initial stage and the influence of ocean currents in order to find out how these organisms expand their habitat and respond to environmental changes.
Adds Dr. Patrick Jodice of Clemson University, an expert in reproductive energetics who was not involved in the study, «When we examine
life history traits we tend to see commonalities within taxonomic families, but Rizzolo et al. demonstrated that within the Gaviidae, Red - throated Loons appear to be quite unique.
They also suggest that a signal in the third codon position could also be associated with convergent
life history traits.

life history traits and population dynamics likely reduced and / or removed populations of many species, including important components of the food web,» in turn shrinking the food chain, scientists wrote in the new report.
Therefore, the aims of my PhD were to 1) determine thermal tolerance ranges of early development and survival of coral larvae 2) assess the extent to which this tolerance varies across space, specifically I aimed to test whether high latitude species have a broader tolerance and 3) test whether difference between adult coral assemblages across a hypothesized dispersal barrier (Great Barrier Reef to Lord Howe Island) can be predicted by
life history traits related to the dispersive larval stages (e.g., mode of larval development, mode of larval nutrition), adult ecology, and / or environmental parameters.
These seven species were chosen because, potentially, their abundance and
life history traits may make them amenable to small - scale fisheries or aquaculture.
Not only they have
life history traits, behavior and physiology strongly influenced by environmental variables but they also lay their eggs in coastal areas prone to sea level rise and cyclonic activity.
