Application of environmental DNA for inventory and monitoring of aquatic species
This fact sheet was created to help biologists and resource managers understand emerging methods for detecting environmental DNA and their potential application for inventorying and monitoring aquatic species. It is a synthesis of published information.

Influence of sex, migration distance, and latitude on life history expression in steelhead and rainbow trout (Oncorhynchus mykiss)
Abstract:In partially migratory species, such as Oncorhynchus mykiss, the emergence of life history phenotypes is often attributed to fitness trade-offs associated with growth and survival. Fitness trade-offs can be linked to reproductive tactics that vary between the sexes, as well as the influence of environmental conditions. We found that O. my kiss outmigrants are more likely to be female in nin

Book review: Gyrfalcons and Ptarmigan in a changing world
The Peregrine Fund has published proceedings of several conferences over the years and has become experts, and this 2 volume set is no exception. The title of the proceedings sounded especially interesting in this era of almost daily accounts in the media about climate change, its causes and its effects on the planet, including its flora and fauna. This 772-page Proceedings is loaded with useful i

Mount Rainier National Park and Olympic National Park elk monitoring program annual report 2011
Fiscal year 2011 was the first year of implementing an approved elk monitoring protocol in
Mount Rainier (MORA) and Olympic (OLYM) National Parks in the North Coast and Cascades
Network (NCCN) (Griffin et al. 2012). However, it was the fourth and second year of gathering
data according to protocol in MORA and OLYM respectively; data gathered during the protocol
development phase followed proce

Riparian litter inputs to streams in the central Oregon Coast Range
Riparian-zone vegetation can influence terrestrial and aquatic food webs through variation in the amount, timing, and nutritional content of leaf and other litter inputs. We investigated how riparian-forest community composition, understory density, and lateral slope shaped vertical and lateral litter inputs to 16 streams in the Oregon Coast Range. Riparian forests dominated by deciduous red alder

Wind erosion from a sagebrush steppe burned by wildfire: measurements of PM10 and total horizontal sediment flux
Wind erosion and aeolian transport processes are under studied compared to rainfall-induced erosion
and sediment transport on burned landscapes. Post-fire wind erosion studies have predominantly
focused on near-surface sediment transport and associated impacts such as on-site soil loss and site fertility. Downwind impacts, including air quality degradation and deposition of dust or contaminants, ar

Estimating direct fatality impacts at wind farms: how far we’ve come, where we have yet to go
Measuring the potential impacts of wind farms on wildlife can be difficult and may require development
of new statistical tools and models to accurately reflect the measurement process. This presentation
reviews the recent history of approaches to estimating wildlife fatality under the unique conditions
encountered at wind farms, their unifying themes and their potential shortcomings. Avenues o

The influence of precipitation, vegetation and soil properties on the ecohydrology of sagebrush steppe rangelands on the INL site
The INL Site and other landscapes having sagebrush steppe vegetation are experiencing a simultaneous change in climate and floristics that result from increases in exotic species. Determining the separate and combined/interactive effects of climate and vegetation change is important for assessing future changes on the landscape and for hydrologic processes.
This research uses the 72 experimental

Data entry module and manuals for the Land Treatment Digital Library
Across the country, public land managers make decisions each year that influence landscapes and ecosystems within their jurisdictions. Many of these decisions involve vegetation manipulations, which often are referred to as land treatments. These treatments include removal or alteration of plant biomass, seeding of burned areas, application of herbicides, and other activities. Data documenting the

Land Treatment Digital Library
The Land Treatment Digital Library (LTDL) was created by the U.S. Geological Survey to catalog legacy land treatment information on Bureau of Land Management lands in the western United States. The LTDL can be used by federal managers and scientists for compiling information for data-calls, producing maps, generating reports, and conducting analyses at varying spatial and temporal scales. The LTDL

Desert shrub responses to experimental modification of precipitation seasonality and soil depth: relationship to the two-layer model and ecohydrological niche
1. Ecohydrological niches are important for understanding plant community responses to climate shifts, particularly in dry lands. According to the two-layer hypothesis, selective use of deep-soil water increases growth or persistence of woody species during warm and dry summer periods and thereby contributes to their coexistence with shallow-rooted herbs in dry ecosystems. The resource-pool hypoth

Are large-scale flow experiments informing the science and management of freshwater ecosystems?
Greater scientific knowledge, changing societal values, and legislative mandates have emphasized the importance of implementing large-scale flow experiments (FEs) downstream of dams. We provide the first global assessment of FEs to evaluate their success in advancing science and informing management decisions. Systematic review of 113 FEs across 20 countries revealed that clear articulation of exp
