This resonates with our recent work on the Bathurst herd. Camera traps showed strong overlap between grizzly bears and caribou during the calving period — but like in Alaska, predator–prey dynamics are only one piece of a much more complex system.

As caribou decline across the Arctic, decisions about how to respond get incredibly complex. Predator control, food security, climate change, and ecosystem shifts are all intertwined.
A thoughtful piece on the Mulchatna herd in Alaska. Well worth the read 🏔️

Sounds super interesting!
Wow! Super cool to see

hiiiiiiiiii it’s me!!!
i am so thrilled to announce i’m now a liber ero fellow!!! 🫶🏼💫🥰
so excited to start this journey and continue working in white sturgeon conservation
i’ll be identifying population stressors that could be leading to mortalities and declines across british columbia

Decisions at upcoming #CMSCOP15 will have far-reaching implications for biodiversity conservation, ecological connectivity, and sustainable development.
We are urging action to halt the accelerating decline of migratory species worldwide, like giant otters.

Can you trust behavioral states inferred from HMMs? 🤔🐾
Using GPS + camera collars on caribou, we show that temporal resolution changes the story. Validate before you interpret!!! 📹

Perú is also afflicted with the scourge of oil and gas development, often in protected areas and indigenous territories. How is it that peoples who have lived in the Amazon for thousands of years have such little say over the fate of their land?

(1) Ostriches are charismatic, but in this case they were still farm animals.
Culls suck, but large-scale animal farming is always going to feature culls, particularly when dangerous viruses are spreading. If you don't want culls, reduce or halt meat consumption. 🌎

The CSEE has reached 1,000 members, and is still growing!
A heartfelt thank you to every member for helping create such a supportive, inspiring community for ecologists and evolutionary biologists across Canada and beyond. 💚 Let's keep building this community together.
Palm: If you build it, they will avoid it: new mines in the Canadian Rockies will further diminish habitat connectivity for G-bears 🧪 conbio.onlinelibrary.wiley.com/doi/10.1111/...
What if you knew him?
What if you loved him?
What if you saw him lying dead on the ground?
How do you turn away from that?
How do you look elsewhere?
How do you just keep moving like nothing happened?
No video of a gun “brandished” at ICE soooooo manyyyyyy cameras were out there. Hmmmm…

Watching horrific events unfold in the US, I’m reminded of Neil Young’s Ohio—written after unarmed students were killed by the state while protesting the Vietnam War.
“What if you knew her and found her dead on the ground… How can you run when you know?”

True, very true. That is why I will have nothing to do with MDPI, Frontiers and Hindawi. Quote: "Now, even the most mediocre researchers receive a flood of invitations to edit one of these countless special issues, which have become a multi-million dollar business" 🧪
Amazing! Way to go Minneapolis!
Many Oz mammals only persist in fox- and cat-free islands or fenced exclosures. The role of these 2 introduced predators on mammalian extinctions should be obvious. Peddling of alternative facts by Compassionate Conservation types required a data-based rebuttal 🧪 academic.oup.com/bioscience/a...

We need action now. Canada missed its 2025 conservation target while species decline and habitats keep being destroyed. Commitments without enforcement and funding are empty words. It’s time to protect nature, not just promise to. 🌱🇨🇦
After some reports of #caribou herd declines, some good news - the Baffin Island herd has reportedly rebounded to more than 48,000 after a low of 4,600 in 2014. New in our news section, www.northerncaribou.ca/news
Caribou wearing hockey pucks?!
Some trail camera photos from summer of 2024 along the Hudson Bay coast in Wapusk National Park, of hockey puck sized something on these animals.
Papilloma is our best guess so far.
Have you ever seen this in caribou @irngutaq.bsky.social
A screenshoot with the highlighted text reading "Researchers might gravitate toward simple models because they are often easier to interpret, reduce concerns of overfitting, and can lead to greater statistical power (e.g., by trimming explanatory variables) (Aho et al. 2014). Favouring simplicity, however, is not always beneficial for causal inference (Coelho et al. 2019). An imprecise but unbiased estimate (i.e., the expected value of the estimate is equal to the true value of the relationship being estimated (Dee et al. 2023; Simler-Williamson and Germino 2022)) is often preferred to a precise yet potentially biased estimate from a simple model."
Reading this paper on causal inference and attribution (onlinelibrary.wiley.com/doi/10.1111/... 🌎🌐), I came across this discussion. I used to favour simple models, even if I thought they could be biased, until my PhD cosupervisor (a math person) asked me "why would you choose a biased model?"
Habitat loss and development in the Rockies drove America's last caribou population in the lower 48 states to near extinction. The few remaining individuals were captured and sent to British Columbia. Now a mulitnational effort is underway to bring them back and protect old-growth forests. 🌎
This infographic from the World Economic Forum shows global risks ranked by severity over two time periods: 2-year (short term) and 10-year (long term). The title reads "Global risks ranked by severity" with the WEF logo in the top right corner. The chart is divided into two columns, with risks color-coded into four categories: Environmental (green), Geopolitical (orange), Societal (red), and Technological (purple). In the short term (2 years), the top risks are: Geoeconomic confrontation Misinformation and disinformation Societal polarization Extreme weather events State-based armed conflict In the long term (10 years), the ranking shows: Extreme weather events Biodiversity loss and ecosystem collapse Critical change to Earth systems Misinformation and disinformation Adverse outcomes of AI technologies Both columns continue to rank risks through position 10, with environmental concerns featuring more prominently in the long-term outlook. The source is cited as "World Economic Forum Global Risks Perception Survey 2025-2026."
New World Economic Forum Global Risks data provides a stark warning: While short-term crises dominate headlines, "Biodiversity loss and ecosystem collapse" jumps to the 2nd highest risk over the 10-year horizon.
The long term is sooner than we think. Science-based policies via IPBES are crucial.🌍
