Carnivores in Northern Latitudes
The first mammals were probably nocturnal (McNab 1978; Kemp 1982) and many extant orders of small mammals have retained this trait. This behaviour is presumably due to the measure of protection from predation that darkness provides (Crawford 1934; Falls 1968; Daan and Aschoff 1982). Large, herbivorous mammals are less restricted to the nocturnal phase (e.g. Bunnell and Harestad 1990) and have b...
متن کاملErythemal irradiances of filtered ultraviolet radiation.
A spectrum evaluator (3 cm x 3 cm) employing four passive dosimeters has been used to evaluate the time averaged spectrum to allow calculation of the erythemal exposures resulting from the predominantly UVA component of filtered solar ultraviolet radiation. An exposure interval of approximately 20 min to autumn and spring sunshine was required for the spectrum evaluator to allow evaluation of t...
متن کاملPersonal exposure distribution of solar erythemal ultraviolet radiation in tree shade over summer.
The personal radiant exposure distribution of solar erythemal UV in tree shade for an upright posture was measured, with measurements over the whole summer for a total of 17 trees. For each tree, the personal radiant exposure distribution was measured for both the morning and afternoon periods. The exposure ratios averaged over all the trees and over the morning and afternoon periods ranged fro...
متن کاملSpatiotemporal exposure modeling of ambient erythemal ultraviolet radiation
BACKGROUND Ultraviolet B (UV-B) radiation plays a multifaceted role in human health, inducing DNA damage and representing the primary source of vitamin D for most humans; however, current U.S. UV exposure models are limited in spatial, temporal, and/or spectral resolution. Area-to-point (ATP) residual kriging is a geostatistical method that can be used to create a spatiotemporal exposure model ...
متن کاملThe erythemal ultraviolet exposure for humans in greenhouses.
A spectrum evaluator has been employed to evaluate the erythemal exposure in late spring and late summer at three sites and five orientations at each site inside a glass greenhouse with black shadecloth over the glass roof. The maximum in the erythemal irradiance in the greenhouse is not necessarily at noon. Over a day, the maximum erythemal exposure occurred on the eastern side of the greenhou...
