Beautiful math predicts lingering periods of equilibrium dynamics when stochastically knocked close to the stable manifold of a saddle. Wonderful talk by shandelle Henson at #JMM2026 @jointmath.bsky.social on recognising saddles and cycles in ecological data.

Are you presenting on your students work at #jmm2026? remember to properly credit it and promote your student! Yun Kang did this really well in her awesome talk on the math of social insects! @jointmath.bsky.social

How do we achieve a better life while reducing emissions and energy consumption? Math! By Alexander Vaninski at #JMM2026 @jointmath.bsky.social. come join us 8am-5pm today in room 149 A for more math ecology, econ, disease and environmental talks.

Awesome talk on modeling illegal smuggling of wildlife and plant products at #JMM2026 @jointmath.bsky.social by Becky Epanchin Niell

Great talk by Suzanne Robertson on competition of mosquito disease vectors #JMM2026 @jointmath.bsky.social at the special session on modeling natural resources.

Looking for food at #JMM2026. I recommend Family Ethiopian Restaurant, I visited last night. 5 min walk from convention centre. Vegetarian entrees start at $12! Fish Dulet, pictured, was excellently garlicky maps.app.goo.gl/B1bj2BGHCTop... @amermathsoc.bsky.social @jointmath.bsky.social

Goals for day 1 at #JMM2026 1) eat good Ethiopian food 2) learn new #math 3) see cool math & street art 4) get over jetlag from Australia 5) acclimate to subzero temps. Accomplished 3/5 @jointmath.bsky.social @amermathsoc.bsky.social

You might be surprised how much impact an in person conversation with your representative can have. Take advantage of being in DC and do this!

Hey if you're in DC, you can just stop by your reps' offices. If you're leaving before the Hill Day after #JMM26 but want to go to the Capitol anyway, grab a few pals and go! Take green/yellow to L'Enfant Plaza then blue/orange to Capitol Hill South.

It's baffling why the Go8 (a group of 8 leading universities in Australia) endorsed a position to weaken environmental laws. Not only do we, the researchers at these universities, disagree, but our research shows it is a bad idea. In just one day, 90 Go8 researchers documented our opposition.

Cute little spikey echidnas have massive poos! The size of a go card! The 💩 can also be detected by dogs. Let's turn 💩 into conservation solutions. Great talk by Kate Dutton-Regester at @uq-cbcs.bsky.social @brisbanetimes.bsky.social @qld.greens.org.au @hugepossum.bsky.social

Don't post your preprint on SSRN (option at many journals). Google scholar often delists papers that have an SSRN preprint. Arxiv preprints are more prominent in scholar. @elsevierconnect.bsky.social @biorxivpreprint.bsky.social @academic-chatter.bsky.social eg. www.sciencedirect.com/science/arti...

Love this Nesbit lecture by prof Ben Andrews on using the diffusion equation as a tool to understand geometry.

Our new paper: If you get a bit more conservation $ should you expand a protected area or improve management? Past work suggests management is often more cost effective but we show when threats are concentrated near edges we find expanding may be optimal doi.org/10.1016/j.bi... 🌍

This is excellent. I once reviewed a grant in a European scheme that had 12 while men on the team. I used similar framing to critique the issues, even though EDI was not included in the criteria. I also followed up with the scheme to ask why no EDI.

the answer to the trolley problem is not to pick who to sacrifice, it’s to dismantle the system that led to an unsafe trolley crossing. if any part of your morality strategy involves picking a group to let die on a hill, throw the entire strategy out. it’s wrong.

New blog: As a grant peer reviewer I consider Equity, Diversity & Inclusion (EDI) even if the scheme doesn't list EDI criteria. Key is to tie the selection criteria to EDI. This is how I do it mathemagicalconservation.wordpress.com/2025/09/23/a... @katehelmstedt.bsky.social @hugepossum.bsky.social

Happy 4^ / 3^2 / 5^2 day!!! (3^2/ 4^2 / 5^2 for us weird Americans) Not too many days satisfy the Pythagorean thm. @amermathsoc.bsky.social @austms.bsky.social @stevenstrogatz.com @monsoon0.bsky.social ht Peter Baxter for noticing. Looking forward to coming back to the US for joint maths in Jan.

Ooh arXiv paper from @matthholden.bsky.social @katehelmstedt.bsky.social about embedding sustainability in undergraduate maths with case studies 👀 Looks very actionable! arxiv.org/abs/2508.07594

Excited for our annual conference on modeling for ecology, biodiversity, sustainability, environment, water, energy, climate, fisheries, forestry, & ag.

Great work classifying ecosystems around the world to create an IUCN red list of ecosystems presented by Prof Emily Nicholson. Shows a small global decline in ecosystems but with extreme variation with some declining rapidly. 🌍 @aciucn.bsky.social @uq-cbcs.bsky.social

Just saw this amazing science article - Beetle grows replica ‘termite’ on back to steal food www.science.org/content/arti.... Despite it being in Australia it wasn't one of the 1,168 species in our Brisbane home but we did find 6 species of rove beetle doi.org/10.1002/ecy....

Bycatch reduction interventions are effective for improving marine species populations but very few studies report the impacts on fisher safety, and other fisher objectives. This is a major barrier to adoption. Great talk by Cindy Vargas @arizonastateuni.bsky.social at #iccb2025.

We can achieve 100% renewable energy in Australia & also protect threatened species impacted by wind and solar developments with only 2-3% increase in electricity bills compared to if we didn't consider threatened species. #iccb2025 great talk by A Rogers

Love the Guidelines on how to give linguistically friendly presentations in English at #iccb2025 for more accessible and diverse conferences @tatsuya-amano.bsky.social docs.google.com/document/d/1...

I really dislike this sentiment re: AI impacts on education: If an assignment can be completed by AI then it is clearly just busy work; educators need to create better assignments. Absolutely not true. Just because AI can do something too doesn't mean that doing it doesn't have pedagogical value.

Every proof in every undergrad math class can be pooped out by the random sentence machine. The point is exactly to engage in the process of generating a proof.

My top tips for conferences 1) have fun, Skip some talks 2) go to the poster session 3) focus your talk/poster around one main message w email address on last slide 4) see who's attending in the program before you arrive and schedule meetings. @iccb2025.bsky.social www.instagram.com/reel/DJQd0_h...

Amazing talk by Dr Helen Mayfield on building models to manage ecosystems by consulting experts in a systematic way (expert elicitation) ... and most importantly an evaluation of whether it worked. @uq-cbcs.bsky.social @martinemaron.bsky.social

The total Australian Research Council budget is $1bn.

Great talk by @alicetwomey.bsky.social on solving the barriers for transdisciplinary research in conservation at the @uq-cbcs.bsky.social seminar. The methods exist we just need to use them. doi.org/10.1016/j.pe...

Delighted to see the final version of my paper for @asn-amnat.bsky.social appear online. In it, I analyze stochastic matrix models to partition the effects of spatial and temporal variation in demography and dispersal on metapopulation growth rates www.journals.uchicago.edu/doi/10.1086/... 1/n

Wow what a planthopper! very cool. Fulgora sp. are such amazing bugs.

I recently read a paper by Kleshnina and others and used it to teach myself some evolutionary game theory techniques. This is a little obscure, so I'll thread below about why this topic matters for humans and the environment 🧵 nadiah.org/2024/11/20/k...

Here, CBCS speaks to Harris Wei-Khang Heng, a PhD student about his research where he investigates the influence of seagrass connectivity on the distribution and population structure of megaherbivores at different geographical scales. Read the full interview here:

Is Australia really a global leader in conserving our oceans? A/Prof Carissa Klein of @uq-cbcs.bsky.social says we have good intentions but need to do better, and we are currently NOT a leader due climate change policy, incl. approving new coal mines, and substandard fishery management funding 🌏

How susceptible are insect pollinators to population fragmentation due to anthropogenic land-use changes? This review identifies research gaps and needs on population genetic connectivity for bees and hoverflies @respublications.bsky.social resjournals.onlinelibrary.wiley.com/doi/10.1111/...

DC area folx in policy, academia, etc: I'm speaking at Georgetown this Fri. It’s in the math dept, but is 100% a nontechnical talk, with attendees from many fields. Join me for "Quantitative Approaches to Social Justice: Race and the Criminal Legal System." Would love to see you. Abstract below.

Long overdue analysis to show how global supply chains stretch around the world to have a major impact on biodiversity in distant countries - those outsourcing resource needs are responsible for much greater cumulative range loss to species outside their own borders than within

Congrats @kleshnina.bsky.social Very well deserved. Look forward to seeing your talk in Nepal.
