W01 - Resource development for Daphnia-microbe host-symbiont systems (Pre-registration required)

Date/Time: Sunday, 2 June, 2024, 9:00 to 17:00
Location: Hall of Ideas F

Lead Organizer: Jeff Dudycha, University of South Carolina ([email protected])

Daphnia and their symbionts have emerged as a powerful system for understanding interactions between freshwater hosts and their symbionts. Much of this research has focused on either D. magna and the bacterium Pasteuria ramosa or D. dentifera and the fungus Metschnikowia bicuspidata. While the latter system has yielded key insights into the ecology and evolution symbiosis, work on it is currently hindered by a few major gaps, including an ability to culture symbionts outside the host, and a lack of genomic and functional genetic resources for the host.

W02 - DIY Sensors Workshop (Arduino Emphasis) (Pre-registration required)

Date/Time: Sunday, 2 June, 2024, 9:00 to 17:00
Location: Hall of Ideas I

Lead Organizer: Mark Gahler, University of Wisconsin-Madison ([email protected])

This one-day workshop is partially derived from the Aquatic Sensors Workshop CFL/NTL put on at Trout Lake Station in 2019. It is primarily intended for graduate students and early career scientists who need to understand very basic electronics as applied to aquatic sensor systems, and those with an interest in making their own simple sensor and data logging systems.

The lecture portion of the workshop will cover the following topics: basic electrical theory, useful electronic components and concepts, multi-meter use, power sources, data communication, and the fundamentals of an Arduino DIY system.

A significant part of the workshop will be hands-on. Students will work with hardware and software to assemble a low-cost Arduino-based sensor suite and data logger.

We will be using the Arduino IDE v1.8.19 ( Please bring a laptop.

Attendance is open but pre-registration would be required at

W03 - Algae and Cyanobacteria Blooms: Track, Identify and Predict

Date/Time: Sunday, 2 June, 2024, 12:00 to 15:00
Location: Meeting Room L

Lead Organizer: Greg Ford, Phytoxigene ([email protected])

Cyanobacteria have the potential to produce harmful toxins which can cause adverse health effects in humans and animals. Monitoring tools are needed to assess environmental conditions and stop blooms in their nascent stages. This workshop will provide a comprehensive introduction to algae HAB monitoring, from the reservoir to the lab. Participants will gain practical skills in the use of three early-detection HAB screening systems that provide different and complementary information: an online multi-parameter measuring & reporting system, an automated microscopic identification tool and a quantitative PCR assay. The workshop will begin with introductions and a brief PowerPoint overview of each technology. Next, we’ll turn to the instruments and run one sample on each so that attendees can compare the information provided by each method.

We will discuss the implications of variables like sampling methodology, preservation, location, and settings on FlowCam imagery and data. We will use the instrument's software to identify dominant organisms in the sample. Participants will be encouraged to ask questions regarding the technology’s benefits and limitations. Throughout the workshop, we’ll point out similarities and differences between flow-through imaging and traditional microscopy, as well as basic plankton identification using semi-automated techniques.

Using the same technology for testing for Covid, workshop attendees will learn how to run a quantitative PCR test. The Phytoxigene™ CyanoDTec is a molecular (DNA) based technology (Real Time PCR) that detects and quantifies the presence of Cyanobacteria, blue green algae, and their toxin producing genes in aquatic environments. Not all Cyanobacteria species produce toxins, therefore the presence of an algal bloom does not immediately defer a risk of toxins being present. The Phytoxigene™ test quantitates both the amount of overall Cyanobacteria present in a water sample along with the number of genes that are responsible for the production of the toxins, including microcystin, cylindrospermopsin, saxitoxin, anatoxin* and guanotoxin* (*new assay in 2023)

We’ll conclude by summarizing takeaways from the workshop and, if time allows, play an interactive game incorporating FlowCam and Phytoxigene images and data to test participants’ knowledge.


Polly Barrowman is the Water Markets Manager at Yokogawa Fluid Imaging Technologies. She works closely with freshwater researchers and drinking water utilities worldwide, helping them to implement FlowCam technology into their phytoplankton research and monitoring programs.

Greg Ford is the Director of Development for Phytoxigene working with customers in Canada and the USA in this capacity since 2016. He started in the field of Aquatic Toxicology before working in biotech and diagnostics before joining Phytoxigene.

W04 - Nutrient Inventories and Fluxes across North America: Methods and Applications

Date/Time: Wednesday, 5 June, 2024, 17:30 to 19:00
Location: Meeting Room KL

Lead Organizer: Dennis Swaney, Cornell University ([email protected])

The workshop aims to engage people in an ongoing initiative to characterize and harmonize nutrient inventories and budgets across North America, with four main objectives:

  • To “meet and greet” those working with nutrient inventories and fluxes
  • To engage in a project to compile papers/methodologies, coefficient tables, and datasets to characterize regional mass balances across all of North America
  • To consider critical issues, such as accessibility of primary data sources, spatial & temporal variation of key variables, uncertainty assessment/ error propagation, regional sensitivity of mass balances to key variables, stoichiometric constraints, interactions with hydrological and climatic variables, implications of policy choices (e.g. effects of biofuel policies and ag practices on nutrient fluxes), & effective communication of outcomes
  • To discuss the development of data repositories, further targeted workshops, etc., possibly including the development of papers or special issues of journals.

W05 - What We Wish We’d Known: Tips About Writing and Publishing Your First Paper

Date/Time: Monday, 3 June, 2024, 12:30 to 14:00
Location: Meeting Room KL

Lead Organizer: Katie Gaines, John Wiley & Sons, Inc. ([email protected])

Are you a student or early career researcher (ECR) interested in publishing your first paper? Are you spinning your wheels on rewrites? Are you unsure where to submit or what to expect from the scientific publishing process? You’re not alone!

Hear ASLO’s 4 Editors-in-Chief and 2 ECRs share what they wish they’d known about the writing and publishing process. After a short panel of helpful advice, the floor will be open for a Q&A.

W06 - Personal Branding 101: Strategies for Marketing Yourself and Your Science

Date/Time: Wednesday, 5 June, 2024, 12:30 to 14:00
Location: Hall of Ideas G

Lead Organizer: Nyazia Sajdah-Bey, Oregon State University ([email protected])

In the digital age, marketing yourself is paramount to connecting your message to a broader audience and securing future employment. The idea of personal branding can be daunting, especially for those with a limited social media footprint. In this presentation, we discuss strategies for digital and physical marketing. Participants will learn about social media engagement, website creation strategies, and online networking. A concept mapping activity will allow participants to brainstorm visual themes and content.
