Article Spotlight  

By Ali Chalberg and Brad Morris


  What the heck is a Snuffbox? Mussels are an essential part of most riverine ecosystems, yet 70% of species are endangered, including all species from the genus Epioblasma (commonly known as riffleshells). The Snuffbox (Epioblasma triquetra) are found in the Midwest, Great Lakes, and Canada. Although they are classified as endangered, there are stronghold populations in the Great Lakes. This project explained the genetic diversity and structure of Snuffbox, determining if genetic differences exist among the populations.

Caitlin Beaver, lead-author, is a Biologist for the United States Geological Survey (USGS) Wetland and Aquatic Research Center in Gainesville Florida, and Dr. Daelyn Woolnough and Dr. Dave Zanatta are faculty in Biology and the Institute for Great Lakes Research at Central Michigan University. Their article “Assessment of genetic diversity and structure among populations of Epioblasma triquetra in the Laurentian Great Lakes drainage.” focuses on Caitlin’s masters research on endangered mussels.

Both Daelyn and Dave have been working with the Snuffbox for many years now. This project gained funding from the United States Fish and Wildlife Service (USFWS) and the Great Lakes Restoration Initiative (GLRI), which allowed them to hire Caitlin to help them with the genetic work. Although some of the field specimens were collected prior to Caitlin starting, she still made her way into the field on numerous trips to collect samples. Field collection comes with its share of fun stories, and this trio had a few to tell! Being a Floridian, Caitlin has a funny recollection of wearing three or more layers in addition to her waders for her field day. What made this such a Floridian story is that it was a warm day in October at about 50°F (warm for Michigan in the fall). To date, this is her coldest field day. In contrast, Dave recalls a field day he had in the Grand River in Ohio where it was over 100°F. He commented on how the mussels “looked so unhappy when we found them.” Throughout the years, they have sampled in all sorts of weather conditions for this and other mussel related projects. Finding endangered mussels is not always easy, Daelyn compared it to a box of chocolates: you know you're going to find something, but when you pick it up you're not sure what it is. The idea being when you're searching for mussels, you will find some unionids, but not necessarily the endangered ones you were searching for.

This project, although conducted in labs at Central Michigan University, was not only an upper Midwest effort to study endangered mussels, but was international. Because the Snuffbox is found in the Great Lakes, they enlisted the help of USFWS as well as Canadian agencies such as Department of Fisheries and Oceans. Daelyn mentions how working internationally is helpful because you can look at more populations than just what is nearby and it can aid in better understanding the species. Caitlin commented on how important international and even national collaboration is because “animals don’t abide by political or state boundaries.”

In our interview, the authors discussed the importance of their broad-scale study of the Snuffbox being that no one had compared the genetic structure and diversity across the entire distribution of the species. Past studies only looked at isolated populations. By looking at the genetic makeup of the whole population, the authors found three distinct populations of the Snuffbox across the Great Lakes Drainage. Snuffbox in the lower Great Lake tributaries were genetically similar, while the populations in eastern Wisconsin and western Michigan were more isolated and distinct. This finding was important because it helps managers better understand Snuffbox, and will provide guidance for augmenting and restoring come of its dwindling populations.

One of the many questions that Daelyn gets asked is, “can you take some [mussels] from here and put them there?” After the project was completed, they found that not every species shows the same genetic structure, and this is one thing that managers are starting to realize. In our interview, Dave stated that mussels are “all filter feeders ... but they have their unique niches within the ecosystem; they all use different hosts; they have different patterns of connectivity between populations … mussels should not be grouped as, yeah, it’s a mussel.” By this he means not all mussels are the same, and have different needs for survival. When asked about future projects spawning from this one, they had many ideas. Daelyn’s lab is in the process of building part of a mussel hatchery in Saline, Michigan. To start, they will be working on more common species currently, but have talked to other agencies to start work on rearing the endangered mussels such as the Snuffbox. Dave mentioned that he would like to see more research involving hatchery propagation and hope more research will go into understanding and protecting endangered mussels.

Unlike most mussels, Snuffbox are still fairly widespread. As previously mentioned, there are a few stronghold populations, unlike other endangered mussels. Dave told us they are not worried that the Snuffbox will go extinct tomorrow, but they are hoping with research and future projects “we can work to make this one a success story.”

We finished our interview by asking the authors if they had any advice for future field biologists. Daelyn had advice for adding to your curriculum vitae: volunteer in other labs and gain transferable skills. Skills such as data entry and analyses, GIS, and genetics are valuable to employers. Caitlin echoed this by telling us about her work with mussel DNA gave her the skills she needed to work with a diverse group of organisms, including other freshwater mussels, manatees, and birds. Dave’s advice was not to be afraid of moving away as traveling gives way to new opportunities. Caitlin agreed as she had moved from Florida to Michigan for this opportunity. Caitlin stated, “don't be afraid of the unknown” and to get out there and try something new. Dave would also like to add that you should attend conferences and join organizations like SFS!

Dear Nick - advice from Nick Aumen  

​  

DEAR NICK: I have always been interested in conservation. I volunteer with an environmental organization in my spare time, but wonder if SFS offers ways in which my aquatic science training can be more directly and effectively employed to address conservation issues.
– WANTING TO GET INVOLVED
  DEAR INVOLVED: It is wonderful that you are interested in conservation issues, and you undoubtedly have much to contribute. Our aquatic ecosystems are under ever-increasing threats from urbanization, a growing population, runoff enriched in nutrients and/or high concentrations of pollutants, and impacts of rising temperatures and other changes. The answer is yes – SFS has a long-standing involvement in conservation issues, and there are ways in which you can get involved. For example, join the the Conservation and Environmental Issues Committee (CEIC). Conservation-oriented society members created the CEIC in the early 1990s. One of its earliest efforts was the creation of a Conservation Resource database – a listing of society members willing to donate their time and expertise to assist environmental organizations in solving environmental problems. Another early effort (1993) was a special series in the journal’s Perspectives section featuring freshwater conservation articles by scientists and activists in the conservation community. For years, the CEIC has funded a graduate student conservation award for conservation-related research. More recently, the CEIC provides a $1,000 travel award to a SFS meeting for undergraduates engaging in conservation research. The members of CEIC raise money for these efforts in various ways, the latest of which is to sell playing card decks featuring photos by SFS members.

In addition to committee activity, the society develops position statements and letters on various topics. Its policy on science and education advocacy (https://freshwater-science.org/about/society-governance/society-statements) states that “It is incumbent upon SFS to make available its collective expertise and knowledge to educate and advocate for the use of science-based insights as a basis for decision-making.” These position statements, approved by the Board and signed by the President, can be proposed by any member or committee, and carry the full weight of all the expertise and knowledge represented by the society. Also, SFS is a founding member of CASS – the Consortium of Aquatic Science Societies – consisting of nine aquatic science societies that can now speak with a much stronger, unified voice on conservation issues than any one society alone. We also are a member of AIBS – the American Institute of Biological Sciences, and can join with them in making policy statements. The SFS provides you with helpful resources to assist in making your voice heard -- https://freshwater-science.org/about/science-policy. This newsletter also features ongoing and newsworthy events within SFS, including news and events related to aquatic conservation topics.

Finally, remember that you can always act locally by taking the time and effort to translate your own science to inform local conservation outcomes via management or policy. For example, say “yes” to an invitation to work on a kids’ STEM event or say “yes” to be the dinner speaker for a local watershed group. There always are opportunities to make your science applicable and informative for those outside the field.

One of the best ways to be effective is to become a more active member of SFS by, for example, volunteering for a committee such as CEIC, or drafting a position statement on a proposed policy or bill for consideration by the SFS Board. Thank you for your interest in protecting our precious aquatic resources!

-- Nick


ITD Q & A with Shelli DiFranco, SFS Media Officer

By Ross Vander Vorste  


Shelli DiFranco is our new SFS media officer. Here she is posing with her son next to a picturesque stream in Olympic National Park. She's curious to know if any members work on streams in this area. Contact Shelli at webeditor@freshwater-science.org.

ITD: Could you tell the Society about your background and how it brought you to serve as Media Officer for SFS?

I am honored to serve as your Media Officer. My background is in environmental communications, though I have alternated between working in the environmental field and the private or nonprofit sectors. I most recently served as the Director of Community Engagement for a water quality nonprofit in Michigan. My family just boomeranged back to Dayton, Ohio.

ITD: Tell us about your role as Media Officer? What type of duties will you working on for SFS?

As Media Officer, I help the Society promote it’s strategic plan and key activities with the goal of increasing membership and engagement. In addition to managing the SFS website, I get to work with the members who are leading various communications channels, such as our podcast and enewsletters. I am also beginning to work with some of the committees, like the policy committee, that may have a need to share their work outside the walls of the Society.

ITD: What goals have you set for yourself or has the Society provided you related to your position as Media Officer?

Ooh, goals are a good question. I started my role in September and am still getting the lay of the land. I’m formulating my specific goals, but in general, I would love to see our membership grow by bringing in students, scientists, communicators, and professionals working in the field.

ITD: What impresses you most about SFS and why are you excited to be a part of this Society?

I have been impressed by so much already! Your passion for the field and seeing how it connects to people’s everyday lives has been inspiring. I am excited to be part of the Society because you are an incredible group of people working on critical issues.


Remembrance

 

Bert Cushing (1931-2019)

By By Arthur Benke,  Steve Thomas, G. Wayne Minshall,  Christopher Robinson, Eric Snyder, Todd Royer, Denis Newbold and David Allan

Colbert E. (Bert) Cushing, long time NABS-SFS member and former NABS President, passed away September 9, 2019 in Loveland, CO. Bert is survived by his wife of 60 years, Jackie, 3 children and 10 grandchildren. He loved his home state of Colorado, being born in Ft. Collins in 1931, receiving his BSc in Fisheries Management (1952) and MSc in Zoology (1956 ) from Colorado State University and living his retirement years in Estes Park. In between his Colorado years, Bert spent two years with the Montana Fish & Game Department, and then attended the University of Saskatchewan where he received his PhD in Biology (Limnology) in 1961. Shortly thereafter he began the rest of his career (35 years) studying various aspects of stream ecology as a Senior Research Scientist with Battelle Pacific Northwest Laboratories at the Hanford Nuclear Reservation.

Bert’s early work at Battelle emphasized the relationship of Columbia River organisms and radioactive elements introduced into the river by the nuclear reactors. After the reactors were closed, his interests broadened to include more theoretical studies on streams throughout North America with professional colleagues from various universities and laboratories. While he published more than 100 papers over a period of at least 5 decades, his best known contributions are his collaborations on the River Continuum Concept (Vannote et al. 1980, Minshall et al. 1983, 1985). But Bert’s published papers are just a part of his many contributions to the science of stream ecology. He edited or co-edited seven books, and wrote five books. Of particular note are “River and stream ecosystems of the world” (edited by C.E. Cushing et al.), “Freshwater ecosystems and climate change” (edited by C. E. Cushing), “Rivers of North America” (edited by A.C. Benke and C.E. Cushing), “Field guide to rivers of North America” (edited by A.C. Benke and C. E. Cushing), “Streams: their ecology and life” (C. E. Cushing and J.D. Allan), and “Streamside: the science and beauty of rivers and fly fishing” (C. E. Cushing). The latter 4 books highlight Bert’s dedication to the importance of informing lay audiences about the beauty and importance of streams and rivers, how they worked and why they need preservation.

Bert continued to lecture and teach in a variety of ways well into his retirement. Along the same lines, Bert published popular articles on stream ecology in Colorado Outdoors, Trout, and The Quill. He taught at Washington State University, the Yellowstone Institute, Rocky Mountain National Park, and held an Affiliate Faculty appointment at Colorado State University and was a beloved and respected member of Idaho State University’s Stream Ecology Center.

In addition, Bert was an avid fly fisherman and the lead content provider for an America On-Line service provided through Trout Unlimited entitled "Ask Dr. Cushing." He was frequently asked all sorts of fly-fishing questions, many of which were answered in his books.

Bert was an active member of several professional societies, but NABS (later SFS) is where Bert was most at home. He was a fixture at our annual meetings well after his retirement. He served NABS most notably as President in 1994-1995 but contributed to the society in many other official and unofficial ways. For many of us, Bert epitomized much of what’s great about our society. He was warm, quick to laugh, and above all else, humble. He was patient and always available to talk to a colleague, or students hoping to become one. Bert was sharp and had the most pleasant way of letting you know you were wrong or headed off the path. Bert’s personality and leadership played an important role in the development of our society and the values we hold dear.


 

A message from our SFS President

Sad losses from our Society

As you may already be aware, we have lost two beloved benthologists and freshwater ecologists in the past few months, Dr. Bert Cushing and Dr. Scott Wissinger. See Bert's remembrance (above) and his obituary. Scott's obituary is here. Also, sadly, Marcelo Ardon lost his dear wife Erin Linquist to cancer in early August. The families of all these SFS members are  in our hearts.

Highlights of SFS and CASS Activities

As a member of the Consortium of Aquatic Science Societies, SFS has been involved in a number of actions to promote the conservation of aquatic resources in 2019. We began the year by co-signing letters to Congress and the White House to recommend bipartisan actions to reach an agreement on fiscal year 2019 appropriations to end the government shutdown that was negatively affecting federal natural resource agencies, many of whom work collaboratively with the science community at-large.

In February, SFS co-signed a letter sent to both the EPA (Andrew Wheeler) and the US Army Corps of Engineers (R.D. James, Assistant Secretary of the Army for Civil Works) requesting a 200 day comment period and additional public hearings on the proposed rule – revising the definition of “Waters of the United States”.

In April, we collaborated with other CASS members to hold congressional briefings to address our concerns with the proposal to revise the definition of “Waters of the US Rule (WOTUS)” because of its elimination of protections for all ephemeral streams and wetlands that do not have a surface connection to navigable streams, and the proposed rule also threatens protections of intermittent streams.

From May through July, CASS members collaborated with lawyers who were writing an amicus brief that was submitted to the US Supreme Court in support of the respondents who brought suit against the County of Maui because wastewater was being injected into groundwater as a means of disposal. A local bay became polluted and various environmental groups sued the county. The EPA has joined the County of Maui arguing that the Clean Water Act identifies point sources as those entering surface waters and as such, discharge into groundwater should not be a regulated release. This case was heard on November 6th by SCOTUS and there should be a decision reached by mid-2020 (reported on NPR: link).

In September, CASS submitted a letter to the EPA (Andrew Wheeler) requesting an extension of the comment period for changes the EPA was proposing that affected the Clean Water Act Section 401 water quality certification process.

In October, we co-signed a 9 page document (with CASS members as well as the American Institute of Biological Sciences, the Ecological Society of America and the Society for Ecological Restoration) that provided comments related to the Clean Water Act Section 401 proposed rule “Updating Regulations on Water Quality Certification”; this was also submitted to the EPA (Andrew Wheeler).

On a somewhat brighter note, CASS members jointly sponsored a booth at the SACNAS (Society for the Advancement of Chicanos/Hispanics and Native Americans in Science) conference in Hawaii in late November. There were several SFS members who went to meet and greet undergraduate students at the conference and encourage them to attend our annual meeting. In the past, we have attracted students from this conference to participate in our INSTARS program!

Book Review  

An Introduction to the Aquatic Insects of North America

Editors R W Merritt, K W Cummins, M B  Berg. Kendall-Hunt, Dubuque, Iowa. 1480 pp

-- review by David Allan

The fifth edition of An Introduction to the Aquatic Insects of North America shows that it is indeed possible to improve on a very good thing. First published in 1978, this invaluable compendium of identification keys to the immature and adult stages of aquatic and semiaquatic insects is an essential reference for aquatic ecologists in North America and beyond. The need to keep current with advances in taxonomy requires new editions at timely intervals, and the editors are to be complemented for successfully taking on this enormous task. Keys are revised and expanded, with new figures added to the 17 taxonomic chapters. Spiral bound, it is meant to be on the bench, next to the microscope, for frequent consultation.

Although especially valued as a taxonomic guide, this book also includes chapters useful to a class in aquatic entomology, including on respiration, habitat use, life history, general ecology, and an overview of various phylogenies. Aquatic insects are important in bioassessment, and this topic is covered well. The entire volume is replete with tables, typically providing an organized summary of a great deal of information. In the bioassessment chapter, for example, one table classifies dozens of bioassessment studies by aspects of sampling, another lists taxa for which molecular methods have been devised, and a third lists useful statistical packages. Indeed, so much tabular information is included in each taxonomic chapter that a separate chapter serves as a guide to the listings, which include common names, habitat, habit, trophic relationships, North American distribution, pollution tolerance values if known, and references. Not content to simply describe categories, this chapter provides heatmaps that show trophic relationships, habitat, and so on by taxonomic groups – a handy way to show, for example, that most Plecoptera are either shredders of leaf matter or engulfers of prey.

Of all of the categories listed at the end of each taxonomic chapter, probably none has seen more use than the trophic relationships typically associated with each genus. These are the functional feeding groups (FFGs) first developed by Cummins in 1973 based on morphological and behavioral mechanisms of food acquisition, allowing a straightforward translation of relative abundance of taxa into relative importance of feeding roles and, presumably, basal resources. Increasingly, analyses based on stoichiometry, stable isotopes, and fatty acids are providing new insights into flexible feeding and the distinction between what is eaten and what fuels growth. Nonetheless, the ease with which an investigator can translate information on the relative abundance of taxa at a site into a depiction of likely energy pathways within the food web makes the continued availability of tabulated trophic roles extremely useful.

An Introduction to the Aquatic Insects of North America is the standard reference on the taxonomy, biology, and ecology of aquatic insects. I can think of no comparable contribution that provides so much benefit to so many freshwater ecologists in the U.S. and worldwide. Editors Rich Merritt, Ken Cummins and Marty Berg, long-time members of the Society for Freshwater Science, have done us all an enormous service.
