@raviranjan.bsky.social & I are teaching a free online workshop with on experimental design for environmental scientists on the 23rd.

We'll focus on using simulations to evaluate how well different experimental designs help achieve your goals.

Please sign up & share! forms.gle/MZTxeQs4UpMr...

Poster for 90 minute workshop on HOW TO DESIGN BETTER EXPERIMENTS, by Mridul Thomas & Ravi Ranjan.

Details: September 23rd 16:00 CEST ; 14:00 UTC

Description:

Experimental designs can make or break an experiment. A good experiment has a clear goal and efficiently uses experimental resources to achieve that goal. In this workshop, we will review what experiments are for, basic and advanced principles of designing experiments, and how to use simulations to evaluate designs before actually doing the
experiment. We’ll do a moderate amount of coding in R and so experience with this would be helpful but is not required. We intend to have small-group discussions to help participants develop their own experiments, and encourage participants to think of a specific question they would like to answer with an experiment.

Historical satellite imagery provides crucial insights, not only for penguin colonies but also for establishing realistic baselines to support conservation efforts and effective management across broad spatial scales. academic.oup.com/bioscience/a...

We've detected penguin guano stains across Antarctica with cold-war era spy satellites. Remarkably, data from the Cape Washington colony shows exceptional stability, defying decades of environmental change. www.biorxiv.org/content/10.1...

A couple of forthcoming workshops on experimental design and data analysis, taught by @christinamcgraw.bsky.social, Peter Dillingham, @sineadcollins.bsky.social, Sam Dupont, and me.

Changing Ocean Biological Systems working group @scor-cobs.bsky.social · Jul 15

We will be teaching two free training courses at the BECoME-2025 conference in Hong Kong next month🌊

Course 1: Designing Multiple-Driver Experiments
Course 2: Data Analysis for Multiple-Driver Experiments

Join us! Apply through the conference website:
www.become2025.com/registration

Training Course 1: Designing Multiple-Driver Experiments

BECoMe-2025 and SCOR’s Changing Ocean Biological Systems infrastructure group are hosting a free training course for researchers interested in learning how to design and carry out multiple-driver (i.e., multiple stressor) experiments that measure responses in microbes, plants, or animals. This training course will guide participants in using the MEDDLE resources to:

• Define a relevant research question
• Identify key drivers, biological traits, and responses
• Select an appropriate experimental design
• Develop a statistical analysis plan

Training Course Details

Time &Date: 9:30 am - 4:30 pm, 18 August 2025 (Monday)
Location: City University of Hong Kong
Participant Limit: 24 researchers (first-come, first-served)
Eligibility: Participants should have experience in designing and conducting single-driver experiments that study biotic responses (e.g. marine warming, ocean acidification).

Conveners: Christina McGraw, Sam Dupont, Sinéad Collins, Mridul K. Thomas, Peter Dillingham

Training Course 2: Data Analysis for Multiple-Driver Experiments

Researchers work hard to conduct interesting and challenging multi-driver experiments, but are often unaware of how best to analyse their data to take maximum advantage of these experiments. In this training course, participants will:

• Learn some of the common statistical challenges that appear in multi-driver experiments and how to solve them
• Work through an example R vignette for a multi-driver experiment
• Simulate an example dataset based on a proposed experiment
• Perform an appropriate analysis and visualise and interpret its output using “literate programming” via R markdown

Training Course Details

Time &Date: 9:30 am - 1:00 pm, 22 August 2025 (Friday)
Location: City University of Hong Kong
Participant Limit: 12 researchers (first-come, first-served)
Eligibility: Attendance at Training Course 1 (Designing Multiple-Driver Experiments) is required, as Training Course 2 builds directly on the concepts developed in the first training course. Participants should have experience with R and good knowledge of regression. Strong Python skills may also be considered, but Training Course 2 will be conducted using R.

Conveners: Peter Dillingham, Mridul K. Thomas, Sinéad Collins, Christina McGraw

Back in my happy place: sending more fully equipped students out to explore lakes in the Black Forest—waters which, to my knowledge, have never been touched by aquatic ecologists. Let the discoveries begin. 🛶🧪🌲

"Absolute teaching bliss" ☺️ is sending two bachelors students in a kayak to collect the first ecological data in over 70 years from a lake so protected, swimming and boating are off-limits. With special permission granted, they’re experiencing something virtually no living human has experienced.🚣‍♀️⛰️🌊

"If you're already trying to live low-impact—recycling, avoiding plastic, limiting flights—here’s a chance to make a meaningful tech choice that aligns with those values. LLMs aren't evil by default, but they’re energy-intensive, and we need to ask whether the benefits we get justify their costs."
