Sampling Grassland habitats in Urban, Suburban and Rural areas of Central Texas using a modified GMIT protocol and Data Recorder Protocol provided a baseline of operations and tested various techniques and equipment prior to large-scale implementation. This 6-month effort combined the Urban Monarch project with testing field data collections techniques with those used by several partners (TPWD protocol) interested in determining best practices, tools and methodologies for evaluating and monitoring habitat for monarchs, other pollinators and grassland birds. Tablet data recorders were far superior that other recorders tested, and also were superior to cell phone applications. Several milk weed planted areas were...

In Texas, the USFWS is currently reviewing 11 mussel species for ESA protection and several of these species (e.g., Cyclonaias petrina, Texas Pimpleback, and Lampsilis bracteata, Texas Fatmucket) have been the primary focus of controlled propagation by several federal hatcheries. To date, information on genetic diversity within and across known populations for these species is incomplete and so the justification for their controlled propagation is unclear, and a genetic management plan to guide propagation activities does not exist. These unknowns raise serious questions about whether any of the 11 proposed species are truly in need of and would benefit from controlled propagation. The overall goal of this project...

Of the vital rates that determine recruitment, breeding propensity (i.e., the proportion of females that lay at least one egg) and nest success appear to have the greatest influence, but breeding propensity remains poorly studied. The few studies that have been conducted reveal it to be highly variable among years (15–77%), likely in response to environmental conditions (e.g., precipitation and wetland availability), and lower than estimates from other dabbling ducks. Thus, quantifying breeding propensity across the mottled duck range in the WGC and identifying factors responsible for its variation remain high priorities for future investigation. Breeding propensity is also among the most difficult vital rates to...

The application of ecological modeling can demonstrate robust, objective, and transparent biological analysis. The Austin Ecological Service Field Office has a multitude of challenging Species Status Assessments (SSA) to complete to support upcoming ESA classification decisions. Previously the Service has invested in development and use of a range of quantitative analytical tools to use in population analysis for SSAs culminating in a recent training class, Species Status Assessment 200 – Strategic use of data: describing population trends for Species Status Assessments. We now seek to apply these tools for more generalized use for a variety of species situations. With this proposed research, population-modeling...
