Metacommunity Dynamics of Gila River Fishes

Goal: If dispersal dynamics of native and nonnative fishes can be predicted by life history strategy, this research will provide a general framework for conservation that considers how community interaction and responses to extreme events (e.g., those predicted by climate change) are influenced by fragmenting populations. By developing decisions support models, hosting workshops, and presenting our findings to regional stakeholder groups, we aim to provide conservation and water resource agencies critical information they can use to inform conservation plans.

Predicting Effects of Climate Change on Riparian Obligate Species in the Southwestern United States

Goal: A central scientific challenge is to generate quantitative predictions of how changes in water availability will affect the amount and quality of riparian wildlife habitat. This project will result in a decision support tool that provides scientific information needed required to restore, enhance and mitigate effects of climate change on riparian vegetation and associated wildlife as well as identify those areas that may be of greatest risk to predicted change.

Springs and Seeps Inventory, Assessment and Management Planning Project

Goal: Work collaboratively with land and resource managers to identify priority watersheds for spring and seep assessments in the Sky Island region of southeastern Arizona, and conduct inventories and assessments using trained volunteers, professional staff and partner personnel. Development of this volunteer monitoring program will provide a model for monitoring climate sensitive resources with limited funding. Develop a regional database for housing and serving historic and newly acquired data from cooperating agencies. Utilize assessments of spring and seep management in conjunction with managers and experts to develop climate change adaptation strategies, decision-support tools and recommendations for management of priority areas.

Resource Management in a Changing Climate: Understanding the Relationships Between Water Quality and Golden Alga Distribution in the Pecos River, New Mexico and Texas

Goal: Golden alga (Prymnesium parvum) is a harmful algal species that can release toxins fatal to fishes, bivalves, crayfish, and gilled amphibians, resulting in immense ecological and economic impacts. This project will enhance understanding of environmental conditions, specifically water quality variables, which promote or regulate golden alga bloom formation in the Pecos River system. Managers will benefit from identifying specific attributes that promote golden alga bloom development and potential toxicity to aquatic species of concern.

Utility Guide to Rainwater/Stormwater Harvesting as an Adaptive Response to Climate Change

Goal: Relatively little guidance exists on how public utilities and agencies can evaluate the suitability and cost-effectiveness of water harvesting strategies to provide tangible and significant benefits to the community. This project will develop a prototype guidance tool for public utilities and agencies to use to evaluate the suitability and cost-effectiveness of rainwater and stormwater capture at various scales for multiple benefits to the community.

Data Provision and Projected Impact of Climate Change on Fish Biodiversity within the Desert LCC

Goal: We will produce data and decision support tools for the conservation, restoration, and management of U.S. priority freshwater fishes in drainages shared by the U.S. and Mexico by compiling and normalizing biodiversity data for all fishes occurring in internationally shared drainages of the DLCC, exclusive of the Colorado and Gila drainages. We will then focus on the Rio Grande drainage where we will model current distributions of selected special interest fishes and project the models into the future under three different climate change scenarios. The results will demonstrate how changing climates will impose directional pressures that will likely tend to shift species distributions.

Remote Acquisition of High Quality Topography (LIDAR) and Multispectral Imagery Data for the Rio Grande through Big Bend National Park: A Critical Need for Climate Change Mitigation Planning

Goal: Use LIDAR imagery to generate vegetation maps and terrain models for the 100-mile reach of the Rio Grande through Big Bend National Park and combine information with one-dimensional flow routing model and monitoring of tributary sediment to enhance ability to quantify future geomorphic and riparian vegetation changes, assess flood risk, evaluate habitat for key species, formulate climate-adapted responses and evaluate exotic plan eradication efforts.

A Landscape Approach for Fisheries Database Compilation and Predictive Modeling

Goal: Produce a defensible data set and decision tool for the conservation of fish and other aquatic and riparian species in Arizona by synthesizing and refining fisheries data and models at the watershed scale, including information on species distribution and abundance and landscape-scale species distribution models. Information collected will be used as part of Arizona Game and Fish Department's and the Western Governors' Association Crucial Habitat Assessment Tool (CHAT) and set the foundation on which managers can assess the impacts of water use, biological invasions, and climate change on biological resources in Arizona. Provide expertise and personnel to New Mexico for shared Species of Greatest Conservation Need.
