Congressional District of University performing the research: Third District K. Identification and statement of the major regional water problem (2 paragraphs) The southeastern United States is a worldwide epicenter of biodiversity for a range of aquatic taxa including fish, crayfish, and mussels. Thermal and dissolved oxygen stressors resulting from altered flow regimes below dams, and projected climate change, can have profound impacts on aquatic organisms since most physiological processes related to growth and reproduction are strongly dependent on temperature and dissolved oxygen levels. These two stressors are closely intertwined because the ability of water to absorb and hold oxygen is temperature dependent. There is a great need for information regarding effects of altered temperature and dissolved oxygen regimes on the diverse aquatic taxa of the southeastern United States. The current USEPA Nationally Recommended Water Quality Criteria (http://water.epa.gov/scitech/swguidance/standards/criteria/current/index.cfm ), for DO thresholds are based on research conducted prior to 1986. Research and analytical techniques have greatly advanced since that period (i.e. Winkler titrations or early DO probes vs fiber optic respirometry systems; graph paper and hand-drawn regressions vs analytical software packages). Furthermore, recommendations for vertebrates are based on only a small number of fish species, while those 2 for invertebrates are based primarily on aquatic insects and don’t include threatened groups such as freshwater mussels and crayfish. There is strong interest from state and federal agencies, as well as private companies, to understand thermal/dissolved oxygen tolerances of fish, crayfish, and mussels due to dam relicensing requirements, minimum flow regulations, and planning for future climate change. These agencies need updated studies that provide information on the impacts of altered temperature and dissolved oxygen regimes on aquatic animal health. We have received seed funding from the USFWS to begin updating our knowledge of thermal/DO tolerances of nongame fish species, with potential for renewal in subsequent years. Alabama Power and the Alabama Department of Natural resources have also expressed interest. We are meeting with Alabama Power in December to discuss this further. Thus the potential for future funding from State, Federal, and private agencies is high. L. Statement of the results, benefits, and/or information (2 paragraphs) For the current effort, we propose to conduct both standard, and proof-of-concept DO/thermal tolerance assays, expanding our current program to include freshwater mussels. Specific goals are as follows: 1) Standard Assays: Determine the relationship between oxygen requirements and temperature for freshwater mussel species found in a Safe Harbor / Critical Habitat Unit subjected to minimum flow regulations. 2) Proof of Concept Assays: Determine whether a non-lethal ETS thermal tolerance assay developed for crayfish (Simcic et al. 2014) can also be applied to freshwater mussels. Communication and funding: Information from the standard assays will be communicated to the Water Board of the City of Auburn, along with water quality data collected by Cliff Weber as part of a closely related project funded by the Board. This will help the Board determine whether or not current minimum flow requirements required of the Lake Ogletree dam are sufficient to protect mussel population from thermal and low oxygen stress in the Safe Harbor reach of Chewacla Creek, a Critical Habitat Unit of Alabama streams. Results will also be communicated to the USFWS, ADCNR, and Alabama Power as an important case study relating minimum flow to freshwater mussel health. Demonstration of our ability to obtain relevant information for freshwater mussels found in Critical Habitat Units is likely to lead to future funding from these agencies. The ETS assay may serve as a valuable, non-lethal tool to detect thermal stress (e.g. Simcic et al. 2014) in aquatic organisms. We propose to use AWR funds to assess the relationship between ETS enzyme activity and temperature for freshwater mussels under laboratory and field conditions. Results will be used to predict the thermal tolerances of representative mussel species and to develop external proposals to determine whether ETS activity is strongly correlated to sublethal effects of thermal stress such as reduced scope-forgrowth (e.g. Simcic et al. 2014). An assay of this type would be extremely useful to an array of state, private, and federal agencies. If verified, it would allow for rapid assessment of thermal tolerance of the ~180 mussel species native to Alabama via non-lethal sampling of tissue from field collected animals. 3 M. Nature, Scope, and Objectives of the research: Due to global climate change, much of the southeastern United States is expected to face warmer temperatures and increasingly frequent and lengthy droughts in the coming decades (Karl et al, 2009). Human demands for water also continue to grow, further exacerbating the effects of drought on freshwater ecosystems (Peterson et al, 2011). The coupling of climate change and increasing water demands for multiple uses (often requiring construction of dams and reservoirs) is particularly problematic for conservation of our natural resources because the southeastern United States harbors the highest species diversity of stream biota in North America (Benz and Collins 2004), including fish, mussels, and crayfish Increasing temperatures and decreased stream flow, can greatly influence life history strategies (Doell & Zhang, 2010), health, and survivorship of aquatic organisms. Dams, common in southeastern river systems, can alter temperature and DO of downstream reaches even in the absence of drought, and these impacts would further exacerbated by increased temperatures and decreased natural flow. When water is being stored behind dams, downstream flow is diminished or even halted altogether. Temperature can increase and DO decline – particularly during the hot summer months. Effects of altered discharge and DO on aquatic organisms play a large role in determining regulations applied to dams with regards to minimum flow requirements. Understanding the interrelationships between climate change, altered discharge patterns, and aquatic community health is of increasing importance to state and federal management agencies. Effects of increasing temperatures and low DO fall into two general categories: lethal and sublethal. Lethal effects involve the death of an organism but can be assessed relatively easily via standard LC50 or LT50 assays (concentration or temperature at which 50% of organisms die within a specified time period). Sublethal effects include a wide range of parameters such as growth and reproductive output. Importantly, sublethal, rather than lethal effects, are typically used for regulatory purposes because they are considered more sensitive and more protective of populations than are regulations based on lethal effects (eg. USEPA 1986a). Oxygen Demand and Tolerance. Standard metabolic rate (SMR) is the minimum metabolic rate required for an organism to survive in a rested and unfed state, and is quantified in terms of respiration rate (mg O 2 / g / h). Increases in temperature typically increase SMR while decreases in DO will eventually limit the ability of an organism to extract sufficient oxygen from its environment to meet its SMR. Because warm water holds less oxygen than cold water, warming temperatures combined with declining DO will prove to be fatal at some point, but tolerance of warm temperatures and low DO varies greatly amongst aquatic species. It is generally assumed that most organisms fit into one of two broad metabolic groups, according to their ability to obtain oxygen from the environment: 1) Oxygen regulators are able to maintain a constant oxygen consumption rate until dissolved oxygen declines below a critical level, while 2) Oxygen conformers exhibit declining oxygen consumption rates as dissolved oxygen decreases (Fig 1). 4 Respiration rate (mg O2 /g/hr) Critical O2 concentration Critical O2 concentration Constant respiration rate Oxygen Regulator 100% saturation Stress and death Stress and death 100% saturation anoxia anoxia Dissolved Oxygen Concentration (mg/L) Figure 1. Schematic of relationship between respiration rate and dissolved oxygen for oxygen regulators (left) and oxygen conformers (right). In both groups, the concentration below which respiration rate declines precipitously is called the critical oxygen concentration (DOcrit), below which severe stress and death of the organism ultimately occurs. SMR allows one to estimate the minimum energy intake required for survival at various temperatures, and the dissolved oxygen thresholds below which an organism is no longer able to maintain its SMR without switching to anaerobic resiration. Thermal tolerance Standard lethal tolerance assays (temperature at which X% of individuals die within a specified time period) are relatively quick (usually ≤ 48 hrs) and easy, but require death of test organisms and yield little information as to anything other than lethal effects. An innovative approach has been recently proposed by Simcic et al (2014) that is relatively quick, but does not require death of an organism. The electron transport system (ETS) assay originally proposed by Packard (1971) has long been used as a proxy for in-situ respiration for marine (salt-water) organisms and to a lesser extent for freshwater organisms (e.g. Madon et al. 1998, Elderkin et al. 1998). It provides a quantitative measure of the potential oxygen consumption rate of an organism if all enzymes function maximally (Fanslow et al. 2001, ref). Simcic et al (2014) showed that the relationship between ETS enzyme activity and temperature could also be used as an indicator of thermal tolerance for crayfish and is species specific. Thus it has potential as a screening tool to distinguish between thermal tolerant and intolerant species. 5 ETS activity (ml 02 /g/h) Species A Species B optimal optimal Too cold cool hot Water temperature Figure 2. Relationship between ETS activity and temperature for thermally tolerant (A) and intolerant (B) species. Adapted from Simcic et al (2014) If the relationship between ETS activity and temperature can truly be used as a simple, yet accurate proxy do determine thermal tolerance ranges, it would revolutionize our ability to quickly and efficiently assess lethal and sublethal effects of temperatures on the overwhelming array of aquatic species in need of protection. For example, there are ~180 species of freshwater mussel in Alabama alone. The long term goals of our collaborative research group are as follows: 1) Determine whether current DO, thermal, and minimum discharge regulations are adequate to protect the rich aquatic biodiversity of the southeastern United States in the face of increasing water demands. 2) Apply up-to-date methodology to assess thermal and dissolved oxygen tolerances of a range of non-game fish, mussel, and crayfish species for which tolerance data is lacking. 3) Test the utility of “up-and-coming” methodologies to improve our ability to assess thermal and DO tolerances of aquatic organisms, and to quantify effects of altered temperature and DO regimes associated with dam discharge. For the current effort, we propose a combination of field and laboratory studies to investigate: 1) Whether the current minimum flow requirements in the Safe Harbor reach of Chewacla Creek are sufficient to protect mussel populations from thermal and dissolved oxygen stress. 2) Whether the ETS thermal tolerance assay recently proposed by Simcic et al (2014) has potential as a rapid screening tool for thermal tolerance of freshwater mussels. 6 Study site and study species: Chewacla Creek is designated as a Critical Habitat Unit for freshwater mussels within the Mobile River Basin (69 FR 40084; USFWS, Alabama Geological Survey). The headwaters of Chewacla Creek originate in Opelika, Alabama. From Opelika, Chewacla Creek meanders south through the community of Beauregard then west to Lake Olgetree – a main-stem reservoir of the creek and a major source of drinking water for the city of Auburn. Below the reservoir, Chewacla Creek continues to flow west, passing by the Martin Marietta quarry. Minimum flow requirements (7,571 m3 / day) from Lake Olgetree have been in effect since 2003 as part of a Safe Harbor Agreement between the federal government, the city of Auburn Water Board, and Martin Marietta. The Safe-Harbor reach consists of two zones: an upper Figure 3. Map of proposed study reach. Numbers zone extending for ~600 m below show gaging station locations. the dam and a downstream zone beginning 3 km below the dam and extending to the western edge of Chewacla State Park (Fig 1). These two zones are separated by approximately 1.5 km of unprotected stretch of Chewacla Creek. Stream widths in the study reach range from 3 to 20 m and depths are generally <1.0m at mean summer base flow conditions. The mussel community is dominated by Lampsilis teres, Villosa lienosa, V. vibex, Utterbackia imbecillis, Toxolasma parvus, and Lampsilis straminea. It also includes a federally threatened species – Hamiota altilis. Despite the minimum flow agreement, flow requirements are sometimes not met due to various issues such as mechanical failure of the dam siphon, and opening of new sinkholes which drain the creek into the Martin Marietta Quarry and can reduce downstream flow. Base flow during the hot summer months can vary greatly from year to year and can be quite low – raising the possibility of thermal and dissolved oxygen stress. We will utilize three species in this study: Utterbackia imbecillis, expected to be relatively tolerant of low DO (Hiestand 1938), Villosa lienosa, expected to be relatively intolerant of low DO (Johnson 2001), and Lampsilis teres, whose tolerance to low DO is unknown. All study mussels will be collected from Chewacla Creek. Hamiota altilis will not be utilized because its rarity precludes collection of sufficient numbers of study animals for the proposed experiments. N. Methods, Procedures, and Facilities DO requirements: We will utilize a state-of-the-art fiber optic respirometry system (Loligo, Inc) to quantify the relationship between temperature (5, 10, 15, 20, 25, and 30 oC), DO, and 7 respiration rate for three mussel species. Mussels will be acclimated for at least one week to appropriate treatment temperatures in 113-L tanks. During acclimation, mussels will be fed commercial Shellfish Diet until 24- 48 h prior to initiation of experiments, allowing for complete gut evacuation (Beamish 1964a). A 12L: 12D photoperiod will maintained throughout acclimation and testing. After the acclimation period, individual mussels will be placed in one of four appropriately sized acrylic respirometry chambers submersed within a 400-L polyethylene tank. Chamber sizing is based on the recommendations of Loligo Systems to reduce water volume while minimizing stress on the test organisms. A control chamber (no mussels) of the same size will be used to measure background oxygen change. Mussels will be allowed to acclimate undisturbed in the chamber for 1 hour prior to measuring oxygen consumption. At the end of the acclimation period, chambers will be closed to external flow, and each mussel allowed to deplete the O2 in its chamber to < 1 mg·L-1. At that point mussels will be removed from chambers, measured (Shell length, nearest mm), and weighed (total wet mass, nearest g). Ammonia concentrations (total ammonia-N) within each chamber will be measured (LaMotte model 3304) at the end of each trial to assess accumulation of metabolic wastes. Oxygen consumption rate will be calculated every 2-6 minutes using the formula: MO2= (O2(i)-O2(f))V· T-1· Bw-1 where MO2 is equivalent to SMR and defined as the oxygen consumption rate (mg O 2·g-1·hour-1), O2(i) is oxygen concentration in water at the start of the measurement period (mg·L -1), O2(f) is the O2 concentration at the end of the measurement period (mg·L -1), V is the volume of the chamber (L), T is the time elapsed during the measurement period, and Bw is the wet mass of the mussel (Cech 1990). To determine the degree of oxygen conformation each species exhibits, and how metabolic rate changes with decreasing DO at each given temperature, MO 2 will be plotted against ambient DO concentration. The relative ability of each species to regulate it’s oxygen consumption with declining DO will be estimated as the ratio of K1/K2 where K1 is the intercept of the regression of oxygen consumption/DO vs DO and K2 is the slope. The lower the ratio, the greater the ability to regulate oxygen consumption, and presumably, the greater tolerance of declining oxygen concentrations (Chen et al. 2001). Minimum DO requirement of each species will be estimated as DOcrit (Chen et al. 2001)(see Fig. 2). Evaluation of ETS thermal tolerance assay Laboratory study: Mussels will be acclimated to the six experimental temperatures, and then held without food for 24-48 hrs, in open glass aquaria. A tissue plug will be extracted from the foot of each mussel, homogenized in liquid nitrogen with a pestle and mortar. ETS enzyme activity of the homogenate will be measured using the same methodology described in Simcic et al. (2014). Thermal tolerance will be assessed via the relationship between ETS activity and temperature (see Fig. 1; Simcic et al, 2014). These relationships will be used to compare theoretical thermal tolerances between the three mussel species. 8 Field study: To verify that the relationships between ETS activity and temperature from the laboratory study are representative of natural conditions, we will PIT tag 18 mussels of the 3 study species and place them in a representative reach within the Safe Harbor reach of Chewacla Creek. Temperature loggers will be placed along the Safe Harbor reach in representative pool, riffle, and run habitats to record ambient water temperature every 30 minutes. Dissolved oxygen (concentration and % saturation) will be measured at the site of each temperature logger on a weekly basis throughout the study period. Every two weeks, from May through January, mussels will be located via a waterproof PIT tag antennae. A tissue plug will be collected from one mussel / species, immediately frozen in liquid nitrogen, and returned to the lab (~18 samples per species). Only one plug will be collected from a given mussel during the course of the study. ETS activity of each tissue plug will be determined as previously described. ETS activity will then be plotted against the average water temperature of the collection site during the 24 hour period prior to collection of the plug. We will then graph ETS activity vs temperature for each species to verify that the relationship is consistent between laboratory and field. Putting it all together: Respirometry data will be used to assess the oxygen requirements of three representative mussel species as previously described. Temperature and oxygen saturation data will be used to model dissolved oxygen concentrations in the pool, riffle, and run habitats of the Safe Harbor reach during baseline flow periods during the summer months when oxygen stress is most likely. Model output will be used to estimate the likelihood of the three habitat types to have DO concentrations above major stress thresholds for relatively “tolerant” and “intolerant” mussel species. This in turn will allow us to assess the probability that minimum flow requirements provided sufficient flow through the Safe Harbor reach to avoid major oxygen stress to the mussel community. Lab and field ETS assay data will be used to determine whether effects of temperature on ETS enzyme activity measured in the laboratory are representative of effects in the natural environment. If so, the potential to develop a field assay for thermal stress of mussels is very promising and data will be used to leverage future funding to investigate this further. Facilities: Respirometry and ETS experiments will be conducted in the Aquatic Respirometry Lab at the North Auburn Fisheries Research Station. This lab has been developed by the PIs and their graduate students over a period of several years with support and funding from the Alabama Agricultural Experiment Station,USFWS, USDA/ HATCH Program, and ADCNR. 9 The lab is equipped with a state-of –the-art fiber optic respirometry system (see inset figures above), custom made respirometry chambers for various sizes and species of aquatic organisms, and holding/acclimation systems with temperature and photoperiod control. Total cost of developing this system has exceeded $100,000. O. Related Research The southeastern United States has the richest aquatic biodiversity and highest degree of endemism in North America; unfortunately, this region also has some of the highest imperilment rates on the continent (Warren et al. 1997; MRBMRC 2010). In fact, over 40% of the federally listed animals in the Southeast Region are freshwater mussels, snails, and fishes that occur in Alabama. Protecting these imperiled animals at landscape scales requires knowledge regarding how multiple uses of waterways impact the risk of imperilment or extinction. Large and small dams are prevalent on the landscape, many of which impact water quality in terms of critical levels of temperature and dissolved oxygen (DO) (Pringle et al. 2000; Santucci et al. 2005). According to a review of 300 Federal Energy Regulatory Commission (FERC) project records, more than 40% of projects had a specific requirement to maintain DO, 37% had monitoring requirements, and 38 and 35% had mitigation recommendations or changes in project operations, respectively (EPRI 1992). The U.S. Fish and Wildlife Service requires information to inform decision making relative to recovery actions, prioritization of stream and river reaches for restoration or reintroduction efforts, and for assistance during permitting where imperiled fishes and mussels are concerned (MRBMRC 2010). Maintenance of minimum DO concentration is required for survival of most aquatic organisms. This can be particularly important when stream flows are interrupted by a dam causing DO and temperature fluctuations that sometimes exceed the tolerances of the organisms living below the impoundment. Dams are often required to maintain a minimal level of dissolved oxygen in 10 discharged water, typically determined based on the temperature and oxygen requirements of a small number of fish species (U.S. EPA 1986a,b, as cited by FERC in their 2012 Biological Opinion for the Coosa River) and invertebrate species, that don’t include freshwater mussels. While we know a great deal about the abiotic and biotic requirements of many sport fishes (e.g., Beamish 1964b; Redpath et al. 2010; Rice and Cochran 1984; Evans 1984), there is a surprising lack of data regarding critical physiological limits of most freshwater mussel species (Haag et al. 2012). As such, threshold values determined for sport fishes may not adequately represent the temperature and dissolved oxygen requirements of other ecologically important species. In certain cases where the flow from impoundments is reduced, temperatures and DO may quickly exceed the tolerance limits of less-studied species while remaining within accepted bounds based on sport fishes and a small number of model invertebrate taxa. In one of the few studies examining dissolved oxygen requirements of freshwater mussels, Chen et al. (2001) showed that DO requirements vary widely between mussel species. Thus DO regulations to protect freshwater mussels will need to be adjusted according to community composition of specific waterbodies. In preliminary work (Hartline 2013), we quantified the influence of temperature and dissolved oxygen on standard oxygen consumption rate and critical oxygen level (DO crit) of five non-game fish species- blackbanded darter (Percina nigrofasciata), bronze darter (P. palmaris), greenbreast darter (Etheostoma jordani), blacktail shiner (Cyprinella venusta), and banded sculpin (Cottus carolinae). Using a combination of intermittent flow and static respirometry, we were able to measure oxygen consumption as a function of dissolved oxygen concentration, as well as the MO2 and DOcrit, at three different temperatures. A low DOcrit is associated with greater hypoxia tolerance presumably because of improved oxygen uptake and transport to tissues at low water oxygen. Consequently, DO crit has been employed routinely as an important measure of hypoxia tolerance in aquatic organisms including fishes (Scott et al. 2008; SpeersRoesch et al. 2012). Chen et al. (2001) concluded that examination of the ability of mussels to regulate oxygen consumption, and quantificiation of DOcrit (see Fig. 2) is a valuable approach for estimating DO water quality criteria for mussels, especially when related to increasing temperatures. 11 References Cited Beamish, F.

Training Potential: This project will provide direct support for one Masters Student (9 months) and one undergraduate student (3 months at 10 hrs/week). The proposed project will also be closely integrated with one externally funded project recently obtained by the PI’s, and another proposed project (under review) that are examing thermal tolerances and oxygen requirements of a range of fish and crayfish species. These additional projects are expected to fund an additional two graduate students, and two undergraduate technicians. By closely working together, graduate and undergraduate students will learn state of the art respirometry techniques for fish, crayfish, and mussels as well as a new, non-lethal, thermal tolerance screening assay that measures ETS enzyme activity. Students will also learn field techniques for collecting fish, crayfish, and mussels, as well as basic water quality monitoring. Graduate students will gain supervisory experience as they help supervise undergraduates in field and laboratory studies. Undergraduate and graduate students will also be given the opportunity to present their findings at Auburn University and professional research conferences, respectively. Graduate students will also take a leading role in writing final reports associated with this project as well as preparation of manuscripts to be submitted to peer-reviewed journals. Graduate student(s) associated with this project are expected to graduate with M.S. degree(s) in May 2017. Undergraduate(s) hired for the proposed study will be juniors and/or seniors and expected to graduate with a B.S. in 2016 or 2017. All students will graduate with degrees from the School of Fisheries, Aquaculture, and Aquatic Sciences. 24 Budget WATER RESOOURCES RESEARCH PROJECT FISCAL YEAR Proposed Starting Date: March 1, 2015 Proposed Completion Date: April 30, 2016 Project Title: EVALUATION OF THERMAL AND DISSOLVED OXYGEN STRESS TO FRESHWATER MUSSELS IN A SAFE HARBOR / CRITICAL HABITAT REACH OF AN ALABAMA STREAM Principle Investigators: James Stoeckel, Cliff Webber, Dennis Devries, Rusty Wright, SFAAS Cost Categories Federal 1.
