The study was designed to assess the strength of the innate linkage of substrate and food in foraging by early juvenile Pallid and Shovelnose Sturgeon and their hybrids and adult Sicklefin and Shoal Chub. The data include information on the fish weights throughout the duration of the experiment as well as observed fish behavior data. Wet weights from fish were recorded to monitor feeding consumption and the behavior data was generated in response to watching the fish during feeding. Information found in the fish weights data table includes the fish name, the tank number, the food treatment given, the light treatment given, the week of the trial, the date when the weight was taken, the substrate material, where food...

The Coastal Cactus Wren is a species of high conservation concern in southern California. The goal of this project was to obtain taxonomic resolution of subspecies boundaries between coastal and desert populations of Cactus Wrens. We collected genetic samples from Cactus Wrens at California desert sites and combined this dataset with previously collected samples from coastal populations to resolve the distribution of subspecies and to determine distinct genetic lineages, gene flow, genetic diversity and effective population size of desert populations. Understanding these relationships will assist managers with development and implementation of a conservation and management strategy that could aim to avoid state...

WERC scientists conduct peer-reviewed research using innovative tools to provide natural resource managers with the knowledge to address challenges to ecosystem function and service in Pacific West landscapes. Four Scientific Themes define the research of WERC scientists: Species and Landscape Response to Human Activity Renewable energy development, urbanization, water abatement, prescribed fires, barriers to movement, and invasive species are among key factors that impact Pacific western US natural resources. To identify potential impacts...
Conservation of imperiled species is frequently challenged by insufficient knowledge of life history and the environmental factors that affect various life stages. The larvae (glochidia) of most freshwater mussels in the family Unionidae are obligate ectoparasites of fishes. We describe the early life history of the federally endangered Southern Kidneyshell, Ptychobranchus jonesi, and compare methods for estimating fecundity and conducting host trials on conglutinate-producing mussel species. Both the glochidial inoculation baths and direct feeding of conglutinates to Percina nigrofasciata, Etheostoma edwini, and Etheostoma fusiforme resulted in successful metamorphosis to the juvenile life stage. Ptychobranchus...

We developed an expert opinion questionnaire to gather information regarding expert opinion regarding the importance of climate variables in determining a species geographic range (Brandt et al. 2017). The data on the Survey_Results tab represent the raw survey questions and responses. Each column in the spreadsheet (except the first four columns, described below) represents a survey question, which is written in the first cell of that column. Each survey response for that question is listed below. Some questions have multi-part answers, and are listed in multiple columns, and appended with letters (e.g., Q8A, Q8B, Q8C, etc.). The first four columns of the spreadhseet represent unique information for that survey...

The original distribution of the study species Trillium texanum is seep spring baygalls in east-central Texas and extreme northwestern Louisiana. Experiments to determine the effects of shading on T. texanum were conducted using short-term shade cloth treatments (full sunlight vs. 30% shading for 2-3 weeks), and a dryness treatment (moist vs. less moist). Mean height and cover responses of individuals were determined in conservation gardens located in Lafayette, Louisiana.
Colorado squawfish (Ptychocheilus lucius), were subjected to dilutions of saline water from natural springs near Glenwood Springs, Colorado, to determine salinity tolerance and aquaculture potential of squawfish in this water. Lethal salinity to 50 percent of the fish (96 h LC50) was 13.1 g l?1, indicating that squawfish survival in higher salinity spring water was not possible. Published in Hydrobiologia, volume 657, in 1992.

The whooping crane (Grus americana) is a listed, endangered species in North America, protected under federal legislation in the United States and Canada. The only self-sustaining and wild population of Whooping Cranes nests at and near Wood Buffalo National Park near the provincial border of Northwest Territories and Alberta, Canada. Birds from this population migrate through the Great Plains of North America and spend a nonbreeding period along the Gulf Coast of Texas at Aransas National Wildlife Refuge and surrounding lands. These data represent predictions from a resource selection function using GPS locations between 2010 and 2016 during migration. This surface is a composite of drought and non-drought conditions...

Data presented are results of surveys for California gnatcatchers and vegetation sampling conducted in 2015, 2016, and 2020 to address two inter-related questions: (1) How have gnatcatchers and their habitat recovered in areas burned by wildfires in 2003, 2007, and 2014?, and (2) What is the current regional occupancy of gnatcatchers throughout their southern California range? Data for the post-fire study were collected in 2015, 2016, and 2020, while the regional occupancy survey was conducted in 2016, and 2020. In 2015, gnatcatcher occupancy as a function of fire history was derived from 324 points in the following fire categories: 2003-2006 (106 points), 2007-2010 (111 points), and 2011-2014 (107 points). In 2016,...

This project has two goals: Goal 1: The goal of this project is to conduct a statistically rigorous study of occupancy to determine the post-fire recovery of gnatcatchers and coastal sage scrub vegetation with the goal of informing management before, during, and after fire. Goal 2: The goal of this project is to conduct rangewide surveys to determine California Gnatcatcher occupancy at a regional scale. Because California Gnatcatchers will be managed through management of coastal sage scrub rather than through species-specific actions, it is necessary to determine the current status of gnatcatchers on protected lands in southern California to understand how gnatcatcher occupancy is related to coastal sage scrub...
