Using Picea/Pinus Ratios from the Wilcox Pass Core, Jasper National Park, Alberta, to Investigate Holocene Timberline Fluctuations

Early Holocene Archeology in Grand Teton National Park

Assessing vegetation changes in timberline ecotone of Nanda Devi National Park, Uttarakhand

Changes in the timberline ecotone vegetation of Nanda Devi National Park (NDNP) was studied over a period of 30 years (1980–2010). Our study based on remote sensing analysis of Landsat MSS and TM images suggests no geographical shift in the upper limit of timberline, while the subalpine forest’s canopy has increased substantially. Decrease in heterogeneous reflectance pattern near upper boundar...

Population Estimates of Kea in Arthur's Pass National Park

The population dynamics of a local group of Kea (Nestor notabilis) was studied at a refuse dump in Arthur's Pass National Park over the course of three successive summers. The mean number of buds that foraged at the dump during the summer was estimated as 20 juveniles, 10 subadults, and 36 adults. An average of 11% of these birds were females. The number of adults was quite stable across years....

Holocene glacier fluctuations

A global overview of glacier advances and retreats (grouped by regions and by millennia) for the Holocene is compiled from previous studies. The reconstructions of glacier fluctuations are based on 1) mapping and dating moraines defined by 14C, TCN, OSL, lichenometry and tree rings (discontinuous records/time series), and 2) sediments from proglacial lakes and speleothems (continuous records/ t...

Black bear (Ursus americanus) survival and demography in the Bow Valley of Banff National Park, Alberta

We studied survival and demography of black bears, Ursus americanus, in Banff National Park (BNP) from 1994 to 2000 to test the efficacy of National Park protection. We monitored 25 radiocollared bears an average of 1.9 years each for a total of 51.8 bearyears. Eighty-two percent of all mortality {n= \\) was human-caused, composed of highway mortality (36%), management mor­ tality (27%) and man...
