Small mammals of the Bitterroot National Forest: Ecological significance and guidelines for management

Publications Posted on: June 22, 2020
Small mammal literature was reviewed to assess the ecological role of small mammals on the Bitterroot National Forest of western Montana. Small mammals fulfill numerous important roles in forest ecosystems by supporting a wide range of predators, dispersing seeds and mycorrhizal spores, altering vegetation through herbivory and seed predation, and preying on insects.

Vegetation patterns and abundances of amphibians and small mammals along small streams in a northwestern California watershed

Publications Posted on: June 22, 2020
Our goal was to describe and evaluate patterns of association between stream size and abundances of amphibians and small mammals in a northwestern California watershed. We sampled populations at 42 stream sites and eight upland sites within a 100- watershed in 1995 and 1996. Stream reaches sampled ranged from poorly defined channels that rarely flowed to 10-m-wide channels with perennial flow.

Management of amphibians, reptiles, and small mammals in North America: Proceedings of the symposium

Publications Posted on: June 22, 2020
Historically the management of public lands from a multiple use perspective has led to a system that emphasizes those habitat components or faunal elements that primarily resulted in some sort of definable economic value. While this often benefitted other species that were not even considered in the original prescriptions, it also negatively impacted others. We no longer can afford to take this simplistic view of ecosystem management.

Development and evaluation of habitat models for herpetofauna and small mammals

Publications Posted on: August 01, 2018
We evaluated the ability of discriminant analysis (DA), logistic regression (LR), and multiple regression (MR) to describe habitat use by amphibians, reptiles, and small mammals found in California oak woodlands. We also compared models derived from pitfall and live trapping data for several species.

Data for National Fire and Fire Surrogate study: environmental effects of alternative fuel reduction treatments

Datasets Posted on: June 08, 2016
Comprised of 12 sites nationwide, the Fire and Fire Surrogates study (FFS) is a comprehensive interdisciplinary experiment designed to evaluate the economics and ecological consequences of alternative fuel reduction treatments in seasonally dry forests of the United States.

Small Mammals, Reptiles, and Amphibians

Publications Posted on: May 12, 2016
This chapter focuses on small mammals, reptiles, and amphibians that inhabit the grasslands within the Southwestern Region of the USDA Forest Service. The chapter is not intended to be an all inclusive list of species, but rather to address the species that play important roles in grassland ecosystems and that often are associated with the management of grasslands. Among the larger rodents discussed here are prairie dogs and pocket gophers.

Population estimation with sparse data: The role of estimators versus indices revisited

Publications Posted on: December 15, 2015
The use of indices to evaluate small-mammal populations has been heavily criticized, yet a review of small-mammal studies published from 1996 through 2000 indicated that indices are still the primary methods employed for measuring populations. The literature review also found that 98% of the samples collected in these studies were too small for reliable selection among population-estimation models.

Transect versus grid trapping arrangements for sampling small-mammal communities

Publications Posted on: December 14, 2015
We compared transect and grid trapping arrangements for assessing small-mammal community composition and relative abundance for 2 years in 2 forest cover types in west-central Montana, USA. Transect arrangements yielded more total captures, more individual captures, and more species than grid arrangements in both cover types in both years.

Staged invasions across disparate grasslands: Effects of seed provenance, consumers and disturbance on productivity and species richness

Publications Posted on: October 01, 2014
Exotic plant invasions are thought to alter productivity and species richness, yet these patterns are typically correlative. Few studies have experimentally invaded sites and asked how addition of novel species influences ecosystem function and community structure and examined the role of competitors and/or consumers in mediating these patterns.

Small mammals of the Bitterroot National Forest: A literature review and annotated bibliography

Publications Posted on: December 31, 2012
Small mammal literature from western Montana and the Northern Rocky Mountains was reviewed to assess the ecological role of small mammals on the Bitterroot National Forest of western Montana and in the Northern Rocky Mountains.
