Century Dictionary and Cyclopedia
- n. In biology: The series of vital phenomena exhibited by an organism in the course of its development from the egg to its adult state. The word refers especially to embryological and subsequent transformations or metamorphoses, if any occur. It incidentally includes the habits, manners, etc., of an organism during the period of its development.
- n. The written description of a life-history; morphological “natural history.”
“Three possible reasons for the record sightings come to mind, says Wayne Perryman, who leads the cetacean health and life-history program at the Southwest Fisheries Service Center in La Jolla, Calif., a unit of the National Oceanic and Atmospheric Administration.”
“Why, there is romance in the life-history of any grass, yes, and adventure, too.”
“In particular, he examined the role of sibling rivalry as an agent of selection on developmental rates, nest-site selection as a source of maternal effects in birds, and habitat-specific variation in life-history traits arising from the spread of a non-native plant.”
“The timing of life-history events in a changing climate.”
“Here, simulations confirm those results under weaker assumptions and explore how different social arrangements shape life-history evolution.”
“Let us suppose that this present year 1867 sic: I suspect this is a scanning error had been the particular epoch in the projected life-history of the world, which the Creator selected as the era of its actual beginning.”
“The abundance, detailed distribution of the new form, and its life-history characteristics are not known, and further studies clearly are needed to determine its conservation status.”
“If a teacher records the alcohol-and-water sequence to its conclusion, the student is not going to get the teacher's life-history and tastes in fruit along with his lesson in physics.”
“Examples include life-history strategies incorporating resting stages and diapause, unique physiological mechanisms to store energy and nutrients, an ability to grow and reproduce quickly during brief growing seasons, and extended life spans relative to more temperate species.”
“For example, some aspects of life-history variation in Dolly Varden on the Yukon north slope appear to be particularly associated with inter-river variation in groundwater thermal properties (e.g., egg size is larger and development time is shorter in rivers that have significant groundwater warming, and reproduction occurs annually in these warmer rivers because sea access allows for earlier feeding, compared to reproduction every two years or less often in colder rivers ).”
