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

Publications Posted on: August 01, 2018
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.

Redistribution of pyrogenic carbon from hillslopes to stream corridors following a large montane wildfire

Publications Posted on: January 30, 2017
Pyrogenic carbon (PyC) constitutes a significant fraction of organic carbon in most soils. However, PyC soil stocks are generally smaller than what is expected from estimates of PyC produced from fire and decomposition losses, implying that other processes cause PyC loss from soils. Surface erosion has been previously suggested as one such process.

An evaluation of multipass electrofishing for estimating the abundance of stream-dwelling salmonids

Publications Posted on: May 12, 2016
Failure to estimate capture efficiency, defined as the probability of capturing individual fish, can introduce a systematic error or bias into estimates of fish abundance.

Fish habitat conditions: using the Northern/Intermountain Regions' inventory procedures for detecting differences on two differently managed watersheds

Publications Posted on: May 12, 2016
Differences in fish habitat variables between two studied watersheds may be related to differences in land management. In using the R1/R4 Watershed-Scale Fish Habitat Inventory Process, for most habitat variables, evaluations of sample sizes of at least 30 habitat units were adequate.

Fire effects on aquatic ecosystems: An assessment of the current state of the science

Publications Posted on: March 03, 2016
Fire is a prevalent feature of many landscapes and has numerous and complex effects on geological, hydrological, ecological, and economic systems. In some regions, the frequency and intensity of wildfire have increased in recent years and are projected to escalate with predicted climatic and landuse changes.

Climate change vulnerability assessments and related literature for aquatic ecosystems: Utah

Pages Posted on: February 01, 2016
This page lists climate change vulnerability assessments and studies that mention aquatic systems in Utah. This list does not necessarily include larger, more regionally based studies and assessments that might also have relevance to this state.
