      Great Basin National Park in east central Nevada encompasses most of the southern Snake Range including Wheeler Peak, which at m is the highest peak in the interior Great Basin. The original detailed surveys of the mammals of this region were made between and by field crews from the Museum of Vertebrate Zoology, University of California, Berkeley. Between and Cited by: 6. Nature Watch Calendar * (scroll below for recurring terrestrial and sky events related to each month of the year#) (# = for coastal area of northern CA/SF Bay Region, including Marin County) (* = Phenology relates to recurring, seasonal events on land and in the heavens, many of which are often predictable based on weather, climate.

    in succession, loss of seed banks, loss of soil nutrients, changes in soil surface organic layers, and changes in underground plant root and reproductive tissues. It is difficult to predict the interactions between climate changes and multiple disturbances, partly because many disturbances are cascading. Drought often weakens tree health. Habitat preferences and population dynamics of northern flying squirrels (Glaucomys sabrinus) and Douglas squirrels (Tamiasciurus douglasii) were examined in old-growth and mature second-growth stands in British Columbia, Canada. Using mark-recapture techniques to estimate population dynamics, I tested the hypothesis that old-growth stands provided higher quality habitat than second-growth.

    ABSTRACT Since , twelve scientists representing several research disciplines — systems ecology, soils, plant nutrition, forest ecology, forest pathology, wildlife ecology, air pollution technology, and meteorology — have collabo- rated in integrated studies to determine the chronic effects of photochem- ical oxidant air pollutants on a western mixed conifer forest ecosystem.

Small-mammal seed predation limits the recruitment and abundance of two perennial grassland forbs Article in Ecology 91(1) January with 75 Reads How we measure 'reads'. The meadow vole (Microtus pennsylvanicus), sometimes called the field mouse or meadow mouse, is a North American vole found across Canada, Alaska and the northern United range extends farther south along the Atlantic coast.

One subspecies, the Florida salt marsh vole (M. dukecampbelli), is found in Florida, and is classified as endangered. Family: Cricetidae. Small mammal populations were live-trapped from to in replicated sites of uncut forest, 20% and 50% volume removal by single tree selection, 20%, 35%, and 50% patch cuts based on openings of – ha, and small ha clearcuts in Douglas-fir forest near Kamloops, British Columbia, by: Chen Reis, Tania Bernath, in Becoming an International Humanitarian Aid Worker, Abstract.

This chapter discusses generalist skills that are sought after by humanitarian organizations and are useful for humanitarian work. The chapter describes the need to have a combination of knowledge of the humanitarian system, specialized or niche skills, and a more general skill set.

Although brush deermice are found on a variety of slopes, including flat mesas and gradual slopes, they seem to prefer locations with very steep slopes, such as hillsides, mountain sides, and canyons (including some slopes with >45% gradient) over more gradual slopes in the same areas [1,30,40,41,73,97,].Findley [] reported that brush deermice were captured on hillsides in an.

CHAPTER 7 SMALL MAMMAL DISTRIBUTION, ABUNDANCE AND HABITAT USE by Klaus O. Richter and Amanda L. Azous. INTRODUCTION. Small mammals are an integral component of most ecosystems.

In the Northwest the regional distribution of small mammals has been described by Ingles () and Maser et al. Progress 10/01/08 to 09/30/09 Outputs OUTPUTS: A series of Douglas-fir test sites were established this past year to test the idea of moving seed sources in response to climate change and evaluate options for adapting to climate change through assisted migration, using silvicultural and genetic options.

In the past years, the Pacific Northwest Research Station has established. Northwest Science publishes on natural history and general science topics, with a geographic focus on the northwestern United States and southwestern Canada.

Project Methods We will expand our understanding of the basic ecology of a few specific species with emphasis on the effects of disturbance processes on their habitats and the species' responses to changing conditions.

In addition, we will expand our understanding of vegetation and disturbance patch pattern for multiple spatial scales (stand, landscape, watershed, drainage basin. Abstract. The use of radioactive tracking of small vertebrates as an ecological tool dates from the early s.

The first published account of this technique is by Griffin (), who recorded nest visits of radioactively marked Semipalmated plover, using an automatic monitoring by: 4. Whether or not atlases can be used as an effective tool for monitoring animal populations relates to the relationship between changes in regional occupancy (as measured by atlas surveys) and changes in local abundance (Gaston et al.
