Document Summary
Humidity: clothing, used by pathologist to determine pmi in early stages, algor mortis- tendency of body to cool down after death (take body temperature, livor mortis- pooling of blood, rigor mortis- body stiffening, late pmi. Infant is left in a diaper for too long: reference data, any data you collect from a body has to be compared to a reference data set, maggot growth rates are typically done under laboratory conditions, examples: Incidental: extension of habitat: spiders and butterflies, types of insects in foresnsic death investigations, 2 types flies, beetles, insect growth and development. Insects grow by going through stages starting with the egg and finishing as the adult stage. Insects are also poikilothermic: dependent on the surrounding temperature, warmer environments develop fast than in cooler temperatures: flies and beetles undergo metamorphosis: the changing of its physical shape, fly development, 3 instar stages, egg.
