An NSF funded program

Advanced Studies Institute on Water Quality and Harmful Algal blooms in lake victoria, Kenya

An NSF-IRES funded program facilitated by BGSU, KiSII University, Technical University of Kenya, Kenya Marine Fisheries Research Institute and the African Center for Aquatic research and education

Bowling Green State University, Kisii University, Kenya, Technial University of Kenya, the Kenya Marine and Fisheries Research Institute (KMFRI), and the African Center for Aquatic Research and Education, are participating in an NSF-International Research Experience for Students-funded, cross-cultural project aimed at providing U.S. students the opportunity to gain international research experience. The project will focus on large lake-comparison to study harmful algal blooms on Lake Victoria, in Kenyan waters and other large lakes, specifically, Lake Erie.

The program invites Masters- and Ph.D.-level U.S. students, and Kenyan counterparts, to apply for the program. It runs from 2020-2023. There is a three-week sampling/field component in Lake Victoria which will be conducted using KMFRI vessels and facilities in the waters of Lake Victoria, Kenya.

If you are a student studying freshwater cyanobacterial harmful algal blooms (CHABs) (or closely related studies) on large freshwater lakes (with a preference for Lake Erie), we welcome you to apply to this program. Please carefully read the description of the program and determine if you meet the program criteria.

Program Background & Importance

 

The North American and African Great Lakes are vital global freshwater resources. These lakes contain nearly half of the world’s available surface fresh water and therefore the security and health of these lakes is critically important especially as freshwater supplies continue to dwindle globally.  One of the most prevalent concerns is human-influenced nutrient (nitrogen and phosphorus) pollution that causes a phenomenon known as a harmful algal bloom.  Harmful algal blooms are overgrowths of algae that can have negative impacts to the environment and/or the health of humans, pets or cattle due to the toxic compounds that can be produced.  Freshwater cyanobacterial harmful algal blooms (CHABs) have become more prevalent worldwide over the past few decades. They occur in lakes, ponds,  

rivers and reservoirs across all 50 states and in many of the world’s most socioeconomically-important waterbodies. Lakes Victoria (African Great Lake) and Erie (North American Great Lake) are the 3rd and 11th largest lakes by surface area and both have regions that are plagued by toxic harmful algal blooms.  Western Lake Erie and Kisumu Bay, Nyanza Gulf, Lake Victoria are similar in that they are both shallow systems that experience heavy nutrient pollution, which results in annual Microcystis-dominated toxic harmful algal blooms.  However, they are different in that Lake Erie is a temperate system dominated by agricultural nutrient pollution, whereas Kisumu Bay is a tropical system that receives a mixture urban and agricultural nutrient pollution.  While much is known about the ecology of the Microcystis-dominated blooms in western Lake Erie, little is known about the ecology, spatial distribution and toxicity patterns of the Microcystis-dominated harmful algal blooms in Kisumu Bay. The Advanced Studies Institutes will provide US graduate students the opportunity to expand their research on water quality and harmful algal blooms in Lake Erie to Lake Victoria. Their research will help fill critical knowledge gaps on the similarities and differences between the blooms that occur in each lake to help us better understand the ecological strategies that Microcystis and other cyanobacteria use to form blooms in fresh waters across the globe.  Furthermore, the participating graduate students will have the opportunity to learn about Kenyan culture and begin to develop their international collaborations by conducting joint research projects with their Kenyan peers and mentors.

Program Description

This is a three-year program (2020-2023). Each Advanced Study Institute (ASI) will provide the opportunity for 10 US graduate students per year to participate and will each last three weeks each January.  We plan to hold this course during January for several reasons. First, Kenya does not have the four season cycle that we are accustomed to in the midwestern United States, but rather the typical wet-dry climate of tropical environments.  In Kenya, January is known for clear, hot days, warm nights and intermittent rain. These conditions are well-suited for cyanoHAB development so we can be reasonably sure the bloom will be present. Furthermore, this timeframe will not overlap with the typical Lake Erie CHAB season and will accommodate students from universities that have a winter session.

 

Each ASI will include lectures by US and Kenyan scientists, two 5-day research cruises onboard the Kenya Marine and Fisheries Research Institute research vessel R.V. Uvumbuzi, followed by laboratory analysis of samples. Every US student will be teamed with a Kenyan graduate student who has a mutual research interest. The student teams will collaborate with their US and Kenyan mentors to develop experimental plans and the teams will give joint presentations during the ASI.  Each team will co-author a scientific presentation that will be given by the US student at an international conference post-ASI. The impact of the ASIs will be broadened by developing innovative contributions to STEM education including training STEM educators.  Students participating in the ASIs will help develop a case study that explores the top-down and bottom-up controls of cyanoHABs in Nyanza Gulf.  This will include discussing culturally-relevant topics such as the influence of point- and non-point nutrient sources, while incorporating all results from the ASI projects. 

 

This Lake Victoria/Lake Erie comparative study program will address fundamental research questions that can inform studies on Microcystis-dominated HABs as they occur elsewhere across the globe.  Below, are four broad research topics we hope to address through the ASIs. Withing each topic we describe potential projects that the students could participate in. However, as we want the ASIs to be a student-led research effort, we strongly encourage students to think creatively to design their own projects using the information listed below only as a guide in preparing their applications:

 

Is the diversity of Microcystis similar in the two lakes, or are there potential distinct  ecotypes present in a temperate dimictic lake vs. a tropical monomictic system?

  • Investigate the spatial diversity of Nyanza Gulf cyanoHAB populations using traditional limnological methods and advanced molecular tools.

  • Determine the spatial extent and viability of sediment Microcystis seed-stocks in Nyanza Gulf

  • Examine spatial patterns of toxic and nontoxic Microcystis genotypes

Do the cyanoHABs in the two lakes respond differently to nutrient availability, changes in temperature and irradiance?

  • ​Investigating the role of different concentrations and forms of nitrogen and phosphorus on Nyanza Gulf -dominated cyanobacterial populations.

  • Understanding the impact that increasing water temperatures has on the structure and function of Nyanza Gulf cyanoHABs

Is the extent of viral lysis, parasitism and grazing to constrain cyanoHABs comparable in the two lakes?

  • Determining the role of microzooplankton and mesozooplankton in top-down control of Nyanza Gulf Microcystis populations.

  • Investigate the role of fungal parasites and viruses on the structure and function of Microcystis populations in Nyanza Gulf.

Are there other, non-microcystin cyanobacterial secondary metabolites or other pathogenic bacteria present that could pose additional threats to ecosystem function?

  • Determine the presence and abundance of saxitoxin, cylindrospermopsin and anatoxin-producing cyanobacteria in Nyanza Gulf.

  • Investigate the spatial distribution of pathogenic bacteria, such as E. coli, within the Nyanza Gulf Microcystis-dominated bloom.

 

Answers to these and other related questions will provide useful information that can help in the subsequent development of cyanoHAB management plans for the bay.

Over the past 15 years, Dr. Davis has studied the ecology of harmful algal blooms (HABs) in marine, estuarine, and freshwater environments. His current research focuses on cyanobacterial harmful algal blooms (cHABs) in large lakes. Lake and coastal regions all over the world are plagued by cHABs including, some of the most socio-economically important, such as the North American Great Lakes, Lake Victoria, Lake Taihu, Lake Okeechobee, and the Baltic Sea, to name a few. Dr. Davis combines long-term monitoring, field- and laboratory-based experiments, emerging technologies, and molecular techniques (quantitative PCR, metabarcoding, 'omics) to investigate changes in the structure and function of cHAB communities.wi
