Huge thanks to master's student Andrea for conducting the experiments, postdoc Mathieu for leading the writing, and all collaborators for making this possible!

We provide the first statistical determination of heat accumulation tipping points. We also demonstrate that exposure to a secondary stressor can suppress tipping points to a primary stressor, thereby removing the ability of phenotypic plasticity to buffer negative impacts on fitness.

2) At 29 PSU, this corresponded to a tipping point of heat accumulation of 28 °C.d above which survival decreased.

3) Reduced salinity below 29 PSU, prevalent year-round in surface waters, suppressed this tipping point, inducing linear decreases in survival when temperature rises above 8 °C.

Happy to share our latest paper: "Sea surface freshening can suppress the thermal tipping point of marine copepods" in Science of the Total Environment! 🌊❄️
We found that:
1) Survival of Calanus copepods tipped and decreased above temperatures of 14–18 °C.

Sea surface freshening can suppress the thermal tipping point of marine copepods

Tipping points govern species distributions, which could be impacted by ocean warming (OW) and sea surface freshening (SSF). Interactions between thes…

Calanus hyperboreus, the largest Calanus copepod in the world. The huge lipid sac inside the body is a key energy source that fuels the lipid-rich Arctic marine food web.

Maybe the same isopod genus parasitising in Calanus hyperboreus. This is a photo I took a few years ago in the central Arctic Ocean.

Great to have this finally out! A whole summer of experiments at @bristolbiosci.bsky.social to look for behavioural and morphological signals of collapse in protists population🔬 Thanks to @duncanobrien.bsky.social @expecocons.bsky.social @dzchilds.bsky.social and John Jackson for the great team work

We look at how press vs. pulse disturbances effect population collapse and how predictable that collapse is 🧪🔬

Multiple ecology faculty positions at @notredame.bsky.social. Apply at apply.interfolio.com/171650. (1/2). 🌎🌐🧪

Multiple Early Career Faculty Positions in Ecology

The Department of Biological Sciences at the University of Notre Dame invites applications for multiple, tenure-track assistant professor positions that will enhance existing institutional excellence in ecology. We are searching broadly for creative and collaborative individuals (1) working at any spatial scale, from local to global, in any system, (2) studying any level of biological organization, from genes to ecosystems, and (3) using any mode of inference, from empirical to theoretical. Applicants should demonstrate research excellence that crosses traditional disciplinary boundaries; ongoing growth in the department will emphasize new hires that use quantitative and/or integrative approaches to study ecological processes. Postdoctoral experience is desirable in applicants. Successful candidates will engage with and benefit from UNDERC, Notre Dame’s 8000-acre environmental field station and home to NEON’s Great Lakes domain, superb on-campus chemical and genomic analytical facilities, an experimental research facility located close to campus, cross-disciplinary interactions through multiple centers and institutes including the Environmental Change Initiative, and a unique Interdisciplinary Graduate Training Program in Environment and Society. New faculty will benefit from Notre Dame’s recent campus-wide Strategic Framework that included the Just Transformations to Sustainability Initiative. Modern research facilities exist in a new environmental research building, which opened in 2025.

Collecting Tigriopus brevicornis from a splash pool for the experiment. These tiny crustaceans are remarkable for thriving in such dynamic and fluctuating habitats.

" While the legal scholars pulled up the definition of biodiversity in international legal conventions, the anthropologists and historians started talking about how biodiversity is vernacularly understood and how the term itself is linked to some historical relation of power and domination."

Khuong Dinh @khuongdinh.bsky.social · Aug 10

"During the workshop, Khuong Dinh (University of Oslo), an ecotoxicologist, raised a simple question to everyone, ‘How do you define biodiversity?’ As it turned out, everyone had a slightly different answer."
