Making the transition to Bluesky like so many others! Hi I'm Hayley, I'm finishing up my PhD in ecology and aiming to enter the applied conservation field in the near future. Looking forward to connecting here!

A thread of #ConservationJobs (and career resources) in conservation-related science, policy, practice, communication, etc.

I'll add to it over time. Focus will be mostly in Canada, with occasional posts for other parts of the world.

Share job ads with me and I'll link here.

Here's another one if you're still looking at options (from a definite superfan 🤩)!

The five sides of the exclosure were held together by zip ties, enabling easy disassembly for storage over the winter. [3/4]

Hayley Spina @hayleyspina.bsky.social · Feb 4

Exclosures allowed parents to easy enter and exit nests, but prevented nest predation by crows, ravens, and gulls. This led to many handfuls of nestlings! [2/4]

The first paper of your PhD is always so exciting! 🤩 An all-#Galbatross effort, "A focus on females can improve science and conservation!" See press release (www.audubon.org/news/researc...) and the study here: onlinelibrary.wiley.com/doi/10.1111/...! #FemaleBirds #FemaleBirdDay

In Research, Ignoring Female Birds Harms Scientific Understanding

A new study shows that ecological research often ignores or excludes data on female birds and behavior, resulting in erroneous assumptions on conservation.

Research was conducted at the Bowdoin Scientific Station on Kent Island, NB. A huge thanks to coauthors: @ryannorrissci.bsky.social, Linda Nong, @sdobney.bsky.social, @passarahformes.bsky.social, Nikole Freeman, Steph Doucet, @dmennill.bsky.social, and Amy Newman. [7/7]

Our results provide the first evidence for a relationship between baseline corticosterone concentrations and double-brooding in free-living passerines and demonstrate the importance of considering breeding stage when assessing female corticosterone concentrations. [6/7]

Hayley Spina @hayleyspina.bsky.social · Jan 31

We also found that the probability of attempting to double-brood was negatively related to baseline corticosterone in females sampled during the first brood nestling stage, but not in females sampled during the first brood incubation stage. [5/7]

Hayley Spina @hayleyspina.bsky.social · Jan 31

Using 12 years of data, we found that female baseline corticosterone levels negatively correlated with body condition and fat score, suggesting that low baseline corticosterone reflected high female quality in this population. [4/7]

Hayley Spina @hayleyspina.bsky.social · Jan 31

We explored the Quality Hypothesis, which proposes that high quality females have sufficient energetic resources available to rear two broods a season. [3/7]

Hayley Spina @hayleyspina.bsky.social · Jan 31

Double-brooding can substantially increase the number of offspring produced per season in songbirds. However, not all females in multi-brooded populations rear two broods per season. We were interested in exploring this variation in a population of wild Savannah sparrows. [2/7]

My first PhD thesis paper is out now in Hormones and Behavior "Corticosterone predicts double-brooding in female savannah sparrows (Passerculus sandwichensis)". Open access here: doi.org/10.1016/j.yh... [1/7]

The insanity of being a fire ecologist in the epicenter of a major fire event, bags packed and ready to evacuate, watching active fire from my window, while taking media requests and explaining to the public, for the 100,000th time how climate change is largely responsible for this

Happy 2025! I'm thrilled to have recently defended my PhD and to be starting a postdoctoral fellowship in wildlife science at the Toronto Zoo in a few weeks 🐢🦇🐍. Celebratory photo from my post-defence trip to the Everglades.

Welcome to the newest spot to get your CatCam updates! I am a PhD candidate studying the impact of outdoor cats on wildlife by attaching animal-borne cameras on owned domestic cats! Hopefully I'll be more disciplined and provide more research updates here than over at that last website!

Thanks for attending Dan, it was great to have you there!

Individual Sphagnum mosses lack structure and are prone to stress and desiccation. As an intertwined community, they fight off massive wildfires and protect the world’s largest soil carbon stock. They also nonchalantly preserve bog bodies.

Learn from Sphagnum. Be the Sphagnum.

So happy to share this new pub with everyone just published at @ibisjournal.bsky.social!
I am proud of it, not only for the science, but also the process of doing the science; one of the more useful learning experiences for folks in my lab.

Hey all! 🦋 A really lovely group of co-authors and I wrote this recent piece for the special issue @society4conbio.bsky.social. We talk about both the challenges and strengths that come with being Black and queer in conservation ✊🏾🏳️‍🌈🌱 Always a re-energizing read for me! ❤️ doi.org/10.1111/cobi...
