The Future of Biodiversity in the Sierra Nevada through the Lake Tahoe Basin Looking Glass 1

چکیده
The Sierra Nevada’s biological distinction and diversity are almost as legendary as its spectacular peaks and beautiful granite landscapes. The Sierra Nevada is recognized as a zoogeographic region on the basis of the coincidence of species ranges (for example, Udvardy 1969, 1975; Welsh 1994). Udvardy (1969) defined the Sierra Nevada bioregion as bounded by the Great Basin to the north and east, the Mojave Desert to the south, and the Central Valley of California to the west. Welsh (1994) further delineated the Sierra Nevada into three latitudinal segments, recognizing shifts in species composition from north to south along the 650-kilometer north-south extent of the largest single mountain range in the contiguous United States.

CHAPTER THREE AIR QUALITY Steven
Introduction Lake Tahoe resides in a high elevation basin separated from the Sacramento Valley by the dominant Sierra Nevada divide along the Crystal Range. Lower ridges of the Carson Range to the east separate the lake from the Great Basin. These physical attributes define atmospheric processes in the Tahoe basin as much as define hydrological processes. The presence of the cold lake at the bo...

متن کاملAircraft measurements of nitrogen and phosphorus in and around the Lake Tahoe Basin: implications for possible sources of atmospheric pollutants to Lake Tahoe.
Atmospheric deposition of nitrogen (N) and phosphorus (P) into Lake Tahoe appears to have been a major factor responsible for the shifting of the lake's nutrient response from N-limited to P-limited. To characterize atmospheric N and P in and around the Lake Tahoe Basin during summer, samples were collected using an instrumented aircraft flown over three locations: the Sierra Nevada foothills e...
متن کاملDwarf mistletoe-host interactions in mixed-conifer forests in the sierra nevada.
ABSTRACT We determined the spatial pattern of dwarf mistletoe (Arceuthobium spp.) associated with two different conifer hosts, white fir (Abies concolor) and Jeffrey pine (Pinus jeffreyi), in forests around the Lake Tahoe Basin and at the Teakettle Experimental Forest, both located in the Sierra Nevada. We also examined a number of host variables and bark beetle incidence to determine how these...
متن کاملA Holocene pollen record of persistent droughts from Pyramid Lake,Nevada, USA
Pollen and algae microfossils preserved in sediments from Pyramid Lake, Nevada, provide evidence for periods of persistent drought during the Holocene age. We analyzed one hundred nineteen 1-cm-thick samples for pollen and algae from a set of cores that span the past 7630 years. The early middle Holocene, 7600 to 6300 cal yr B.P., was found to be the driest period, although it included one shor...
