Climate Distance Mapper
Climate Distance Mapper
Climate Distance Mapper is a spatial decision-support tool designed to help land managers match seed sources with restoration sites. Plant populations are commonly adapted to local climate gradients and frequently exhibit a home-site advantage.

Data for calculating population, collision and displacement vulnerability among marine birds of the California Current System associated with offshore wind energy infrastructure (ver. 2.0, June 2017) Data for calculating population, collision and displacement vulnerability among marine birds of the California Current System associated with offshore wind energy infrastructure (ver. 2.0, June 2017)
The U.S. Geological Survey, Western Ecological Research Center (USGS-WERC) was requested by the Bureau of Ocean Energy Management (BOEM) to create a database for marine birds that would allow quantification and species ranking regarding vulnerability to offshore wind energy infrastructure (OWEI). This was needed so that resource managers could evaluate potential impacts associated with...
Blood variable data for clinically normal and clinically abnormal Mojave desert tortoises (Gopherus agassizii) in 2013 Blood variable data for clinically normal and clinically abnormal Mojave desert tortoises (Gopherus agassizii) in 2013
To improve our understanding of health and immune function in tortoises, we evaluated both standard blood diagnostic (body condition, hematologic, plasma biochemistry values, trace elements, plasma proteins, vitamin A levels) and gene transcription profiles in 21 adult tortoises (11 clinically abnormal; 10 clinically normal) from Clark County, NV, USA. Necropsy and histology evaluations...
Mercury contamination in Annas hummingbirds Mercury contamination in Annas hummingbirds
Heavy metal contamination (n=17 metals) of feather and tissue samples from live and deceased Anna's hummingbirds (Calypte anna) was evaluated. Feathers taken from live birds are low in sample weight, therefore a novel method was used in feather sample preparation. Feather samples were then analyzed utilizing an inductively coupled plasma mass spectrometry (ICP-MS) assay. In addition, ICP...
Subalpine Meadow Plant Communities in Yosemite and Sequoia and Kings Canyon National Parks, 2011-2012 Subalpine Meadow Plant Communities in Yosemite and Sequoia and Kings Canyon National Parks, 2011-2012
This publication presents data collected within meadows from samples used to assess meadow plant community responses to recreational pack stock as part of a USGS Natural Resources Preservation Project. High elevation meadows are a vital ecological component of mountain systems throughout western North America. They provide critical habitat for wildlife, supply key ecosystem services, and...
Monthly densities of the snail Cerithideopsis (Cerithidea) californica at Carpinteria Salt Marsh, California USA, February 2012 to January 2014 Monthly densities of the snail Cerithideopsis (Cerithidea) californica at Carpinteria Salt Marsh, California USA, February 2012 to January 2014
Each month (except March 2012), we collected detailed data on the density, size distribution, and infection status of intertidal snails from ten fixed sites as part of a broader effort to understand food webs in California Estuaries. The study site was Carpinteria Salt Marsh Reserve, California USA, (University of California Natural Reserve System), which comprises 9 Ha tidal channels, 2...
California Red-Legged Frogs in Point Reyes Coastal Dune Drainages (2015) California Red-Legged Frogs in Point Reyes Coastal Dune Drainages (2015)
California Red-legged Frogs (Rana draytonii) are typically regarded as inhabitants of permanent ponds, marshes, and slow-moving streams, but their ecology in other habitats, including coastal dunes, remains obscure. To avoid and minimize potential negative effects of dune restoration activities, we studied the spatial ecology, habitat selection, and survival of California Red-legged...
Monthly trematode infections of the snail Cerithidiopsis (Cerithidea) californica at Carpinteria Salt Marsh, California USA, February 2012 to January 2014 Monthly trematode infections of the snail Cerithidiopsis (Cerithidea) californica at Carpinteria Salt Marsh, California USA, February 2012 to January 2014
Each month (except March 2012), we collected detailed data on the infection status of intertidal snails from ten fixed sites as part of a broader effort to understand food webs in California Estuaries. The study site was Carpinteria Salt Marsh Reserve, California USA, (University of California Natural Reserve System), which comprises 9 Ha tidal channels, 2 Ha salt flats, 17 Ha upland...
Data release for persistence of historical population structure in an endangered species despite near-complete biome conversion in Californias San Joaquin Desert Data release for persistence of historical population structure in an endangered species despite near-complete biome conversion in Californias San Joaquin Desert
The recency of large-scale land conversion in Californias San Joaquin Desert raises the probability that the regions numerous endemic species still retain genetic signatures of historical population connectivity. If so, genomic data can serve as a guidance tool for conserving lands that once supported habitat for gene movement. We studied the genetic structuring of the endangered blunt...
Bird Distribution Surveys at Carpinteria Salt Marsh, California USA, January 2012 to March 2013 Bird Distribution Surveys at Carpinteria Salt Marsh, California USA, January 2012 to March 2013
We collected detailed spatial data on birds as part of a broader effort to understand food webs in California Estuaries. The survey area was Carpinteria Salt Marsh, California USA, which comprises 9 Ha tidal channels, 2 Ha salt flats, 17 Ha upland habitat, 6 Ha tidal pans, 52 Ha vegetated marsh, and 2 Ha tidal flats. In 30 surveys, we mapped 21,486 birds comprising 88 species interacting...
Distribution and mapping of the snail Cerithideopsis (Cerithidea) californica at Carpinteria Salt Marsh, California USA, June to August 2012 Distribution and mapping of the snail Cerithideopsis (Cerithidea) californica at Carpinteria Salt Marsh, California USA, June to August 2012
We collected detailed spatial data on the density and size distribution of intertidal snails as part of a broader effort to understand food webs in California estuaries. The survey area was Carpinteria Salt Marsh, California USA, which comprises 9 Ha tidal channels, 2 Ha salt flats, 17 Ha upland habitat, 6 Ha tidal pans, 52 Ha vegetated marsh, 2 Ha tidal flats. Using nearly 4,000...
At-Sea Distribution and Abundance of Seabirds and Marine Mammals off Southern California GIS Resource Database: Aerial seabird and marine mammal surveys off southern California, 1999-2002 At-Sea Distribution and Abundance of Seabirds and Marine Mammals off Southern California GIS Resource Database: Aerial seabird and marine mammal surveys off southern California, 1999-2002
Background - Interest in developing alternative sources of renewable energy to reduce dependence on oil has increased in recent years. Some sources of renewable energy being considered will include power generation infrastructure and support activities located within continental shelf waters, and potentially within deeper waters off the U.S. Pacific coast and beyond state waters (i.e...
Data for Southern Sea Otter Range Expansion and Habitat Use in the Santa Barbara Channel Data for Southern Sea Otter Range Expansion and Habitat Use in the Santa Barbara Channel
The current study was designed to provide critical information for resource managers (specifically the Bureau of Ocean Energy Management, henceforth BOEM, and the U.S. Fish and Wildlife Service, henceforth USFWS) about the spatial ecology, population status, and potential population threats to sea otters in Santa Barbara Channel, with particular reference to exposure to manmade...
