ENVS200 Chapter Notes - Chapter Chapter 3: Diapause, List Of Weather Records, Photoperiodism
Document Summary
Conditions: physiochemical features of the environment such as its temperature, humidity, ph, or, in aquatic environments, salinity. Pla(cid:374)t(cid:859)s resour(cid:272)es: co2, (cid:449)ater, (cid:374)utrie(cid:374)ts a(cid:374)d solar radiatio(cid:374) Organisms may compete with each other to capture a share of a limited resources: e. g. rabbits are a resource for eagles, a rabbit eaten by one eagle is not available to another eagle. Photoperiod: length of the period of daylight in each day. Diapause: a state of arrested development or growth, accompanied by greatly decreased metabolism, often correlated with the seasons, usually applied only to insects. Acclimatization: the ha(cid:271)ituatio(cid:374) of a(cid:374) orga(cid:374)is(cid:373)(cid:859)s ph(cid:455)siologi(cid:272)al respo(cid:374)se to e(cid:374)(cid:448)iro(cid:374)(cid:373)e(cid:374)tal conditions (usually applied to natural environments) Organisms respond to each condition in their environment, the effects of conditions may be determined largely by the responses of other community members. An organism will suffer if its food is another species that cannot tolerate an environmental condition.
