To evaluate the potential effects of climate change on wildlife habitat and ecological integrity in the northeastern United States from 2010 to 2080, a University of Massachusetts Amherst team derived a set of climate projections at a fine spatial resolution for the entire Northeast. The projections are based upon publicly available climate models.This dataset represents the growing season degree days (number of days in which the average temperature is > 10 degrees C) using one of two IPCC greenhouse gas concentration scenarios (RCP8.5). The dataset is intended to represent typical growing season degree days for the year 2060 rather than the actual growing season degree days. MAP UNITS ARE THE SUM OF DEGREES THAT...

Synopsis: This study evaluates whether previous observations of a higher percentage of parasitism and parasitoid diversity in a complex agricultural landscape, relative to a simple landscape, represent a general phenomenon. Rates of parasitism and parasitoid diversity of the armyworm (Pseudaletia unipuncta) were assessed in three replicate (Onondaga, Ingham, and Benton) regions in southern Michigan. Within each region, a simple landscape (primarily cropland) and a complex landscape (cropland intermixed with mid and late successional noncrop habitats) were identified through analysis of aerial photographs. In each landscape, three maize fields were selected, and second to fourth instar P. unipuncta were released...

Combined core and corridor areas used to identify the landscape context of potential implementation opportunities in terms of enhancing functional connectivity. Data generated by The Conservation Fund as part of the Midwest Wind Energy Multi-Species Habitat Conservation Plan (MSHCP) and NiSource MSHCP green infrastructure network design processes.
This item provides the ScienceBase query that identifies components of the fish habitat assessments within the Southern Plains States. It also contains a link to a configuration file that pulls these pieces of information into a logical order. This information can be accessed through the ScienceBase API to display a summary of fish habitat assessment information for the Southern Plains States.

Southern Plains States Fish Habitat Partnerships’ 2010 - 2015 Actions to Make a Difference Partnerships - Reservoir Fisheries Habitat Partnership, Southeast Aquatic Resources Partnership, Great Plains Fish Habitat Partnership, Desert Fishes Habitat Partnership, and Western Native Trout Initiative Funded a project to stabilized 3,050 feet of shoreline on Olpe City Lake, Kansas. Assisted partners in installation of a fish barrier on Lovewell Reservoir, Kansas to prevent fish loss during irrigation releases. Evaluation is ongoing but preliminary results show a large increase in the forage base. Provided funding for 400 plastic fish attractors that were installed in six Texas reservoirs: Sam Rayburn, Toledo Bend,...

Partnership - Southeast Aquatic Resources Partnership The Harpeth River drains nearly 900 square miles in middle Tennessee and flows through one of the fastest growing regions in the country. It is a state designated Scenic River in Davidson County, within 30 minutes of downtown Nashville. The river is one of the most archeologically and historically significant rivers in the state. However, the project area was listed on the U.S. EPA Section 303(d) list for siltation and habitat alteration, nutrient enrichment and low dissolved oxygen. Low dissolved oxygen was particularly an issue above a 6.2 foot low head dam near Franklin, Tennessee. Dissolved oxygen measurements at this dam were below state standards, and...
The United States is home to more than 3,000 fish species and over 322 million people, and they all depend on the same water. Healthy aquatic resources are vital to the integrity of the United States and essential for sustainable fish populations. Unfortunately, in many places around the United States, fish and the habitats on which they depend are degraded or in decline. Almost 40 percent of the nation’s freshwater fish species are considered at risk or vulnerable to extinction. Habitat loss is the most common cause for extinction of freshwater fish in the United States over the past century, and many saltwater fish are also in decline due to habitat degradation. In 1997, Congress declared that one of the greatest...

Cross section of basaltic next exposed by erosion in Grant Ridges, 6 miles northeast of Grant, view looking southwest in sec. 3, T. 11 S., R. 9 W. Basalt in core is jointed in vertical columns and surrounded by a thin zone of platy jointing developed along the contact with white tuff. Bedded breccia overlies the tuff, and basaltic lava overlies the breccia on the far side of the cone. The tuff, chiefly rhyolitic, was erupted from Mount Taylor. Valencia County, New Mexico. 1931.

In the mostly arid Southwestern United States, water availability (hydrology – a key fish habitat process), wildfires, and grazing intensity are important disturbances that are known to have major, negative effects on fish habitats. While this assessment indicated that many of the streams in this region are in good condition, a number of key habitat variables (i.e. water availability, wildlife frequency and intensity, and grazing intensity) could not be directly included in this assessment because national datasets of these disturbances and their measured variable are unavailable. Their absence from this assessment, along with absences of other disturbances, has likely produced an overestimation of habitat condition...
Heavy rainfall occurred across Louisiana, Texas, Arkansas, and Mississippi in March 2016 as a result of a slow-moving southward dip in the jetstream, funneling tropical moisture into parts of the Gulf Coastal States and the Mississippi River Valley. The storm caused major flooding in the north and southeastern parts of Louisiana and in eastern Texas. Flooding also occurred in the Mississippi River Valley in Arkansas and Mississippi. Over 26 inches of rain were reported near Monroe, Louisiana over the duration of the storm event. In March 2016, U.S. Geological Survey (USGS) personnel made over 490 streamflow measurements at over 375 locations in Louisiana, Texas, Arkansas, and Mississippi. Many of those streamflow...
