Grizzlies, cougars and wolves not only kill #mountaingoats, they also stress them enough to impact recruitment. 🐻🐐

Here's our new @FunEcology paper: https://t.co/aOw68FWich. @cen_nord @NSERC_CRSNG

How does the return of wolves to Washington state affect elk? Our new paper, published in @ESAEcology, examines how pressure from wolves, cougars, and humans shape elk movement and mortality as part of the #WAPredatorPreyProject 🦌 🐺🌲 ... a 🧵(1/6)

My first PhD chapter is out as a preprint!

We formulate step selection functions as GAM-like models, which can be fitted in mgcv. This allows for the inclusion of non-linear effects/interactions, as well as individual-level and spatial random effects!

I have never worked harder on a paper in my entire life! Here, with @conversesj and @LabGardner, we merge IPMs and IBMs in a spatially explicit projection model to estimate current and project future population dynamics of wolves in Washington State. 🐺

📢New OA Paper📢

Happy to share our new paper on how top-down and bottom-up factors influence red fox occurrence and persistence in winter.

Wonderful to work with @BrynEvansTweets, @AlessioMortell2, and @remington_moll on this study

Our step selection analysis review now in MEE!

We describe choices of "control" points through the lens of numerical integration, to unify them and explain why some work better.

Control points are often a numerical tool with no biological interpretation

The contrasting effects of two abundant prey (lemming, geese) underline the importance of studying behavioural changes of predators in multiprey systems and to explicitly integrate behavioural-numerical responses in multispecies predator–prey models.

🚨NEW PAPER 🚨
Predator home ranges are dynamic; does it matter for their prey?

Changes in #predator home range size generate apparent competition between #prey in the #arctic.

The study provides empirical evidence of a behavioural-numerical responses, through changes in predator space use, as a driver of indirect interactions in a multispecies system. Behavioural response of predators to their prey are common and can act faster than demographic rates.

New paper with @AparnaLajmi and Dror Hawlena in #BiologyLetters
We find that risky habitats are occupied by prey - but they are small. Are they competitively excluded by larger conspecifics? But we see no contests! Find out how and why https://t.co/KIKJPiJlvR

The world is facing climate collapse but Australia keeps digging up coal and chopping down forests. That’s why I’m on a #ClimateHungerStrike until the Australian Government takes real action. Read more and please sign my petition here.👇🏽 https://t.co/ZtCwI6K0QQ

What can blood metabolites tell us on the nutritional condition of breeding seabirds? Read this new publication in @CompBiochPhys!

Congratulations @jackson0lauren for your first paper. A publication during an Honour's Thesis is a huge accomplishment!

[Alexandra Langwieder @al_langwieder]

Our first polar bear paper from the EMR is out! 🐻‍❄️In it we share the approach we’ve been taking and how it could be used to expand community-based polar bear research in the North. So proud to work with these co-authors on my first first author paper!
