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

The Voyageurs Wolf Project of Northern Minnesota tags & documents grey wolf ecology & behavior: www.voyageurswolfproject.org

The video you see here is confirmatory proof:
Wolves. Love. Blueberries.

As much as 83% of a wolf's calories in summer months comes from eating berries.

thank you!!! 😊 🫶🏼

Differences in the relative percentage of life stages exposed to climatic stressor(s) (a, c, e) or assessed for physiological traits (b, d, f) across the traits (top row), taxa (middle row), and climate change stressors surveyed (bottom row). Studies categorized in “development” yet assessing adult animals are studies measuring whole animal size, growth or measuring multiple life stages. Other stressors not captured by these broad categories (i.e. diet, UV radiation; n = 6) and studies investigating interactions between climatic and non-climatic stressors (n = 138) are not displayed for clarity. Note that the values do not correspond to strict percentages of studies because some studies have investigated multiple life stages, traits, taxa or stressors. Representative diagrams were drawn by me!

We asked are embryos understudied in conservation physiology?

Turns out, despite the increasing recognition of the ecological importance & sensitivity of embryos, we found no evidence that embryo research has gained traction over the past 10yrs

Embryos are largely understudied in a representative sample of journals in conservation physiology Abstract. Understanding how animals respond to environmental stressors across their life cycle is essential for predicting species' vulnerability to climat

this paper was lead by @patricepottier.bsky.social and was a large group effort across many institutions and countries 🫶🏼☺️

The aurora last night in Beaver, Alaska was just incredible. This is a real-time video (not sped up) of the crazy motion I saw. Also, look how BRIGHT it is, wow!

hiiii it’s me!!

as a pretty burnt out scientist but i’ve found joy again in making ceramics :)

i’m working on my first small batch drop that will be inspired by my love of color and the natural world

if you have instagram and want to be friends find me @madart_ceramics

👩🏻‍🔬🧪🌎🍒🫐🐚💫

thank you!!!

thank you so much!! 😊

i’ve been dabbling in pottery to keep some portion of my sanity together and turns out i super love it and want to make it my whole life 💫🥲

is this the scientist to artist pipeline? 🧪👩🏻‍🔬🌎

here are some to go cups i made recently! hand painted fruits on speckled clay

a juvenile sturgeon madison is holding prior to release, this size sturgeon loves a cuddle puddle!

3 sturgeon stickers created by madison, a white sturgeon, pallid sturgeon, and atlantic sturgeon

happy #sturgeonsaturday yall 🧪👩🏻‍🔬 🌎

Did ya know that during winter sturgeon do a thing i call cuddle puddle? they find a deep hole to overwinter in & hang out cuddle puddling until spring! we are working to identify & protect these areas now

support the sturgies, get a sticker: tinyurl.com/2fjnxy7w

Excellent piece by Matz @heatshok.bsky.social and colleagues discussing the dire status of Caribbean reefs, and potential plans and policies that can be implemented if these reefs are to have any chance. Check it out in PNAS!

abolish ice

AOC: "An ICE officer had violently pushed a woman to the ground and he had come over to help get her up and that is what precipitated this incident that very quickly led to an execution in the streets. What we are seeing here is a momentous pivotal moment for the United States."

yooo everyone!!

will did a super cool study with big implications for salmon!!

He was able to create biomarkers using teeny tiny pieces of gills (non lethal) to identify if a salmon is food limited or not

this means they can go in the wild and determine if, when and where salmon are starving 🧪🌎👩🏻‍🔬

New research out in @conphysjournal.bsky.social We use RNA sequencing to identify gill markers for food deprivation in Chinook salmon.

academic.oup.com/conphys/arti...

We will deploy these markers with panels for other stressors and pathogens to evaluate impacts on survival of wild salmon

newwwww illustration below :) check out this sturgeon paper!!!

Graphical depiction of the changes to the muscle transcriptome that result in persistent enhanced growth phenotypes in lake sturgeon

What underlies plasticity and persistent enhanced growth following warm temperature exposure?

We sequenced lake sturgeon muscle tissue to find out

A variety of molecular mechanisms and cellular changes work together to increase muscular development across timescales

sometimes I do field work in the most gorgeous water (Harrison river, BC) and you can see the sturgeon swim away forever 🥹

this is a nice close up of the scutes that cover sturgeon for protection, they have several rows of these bony plates that can be really sharp!

#sturgeonsaturday 🧪👩🏻‍🔬🌎🌐

did you know we had ~80 huge sturgeon die this year (that we know of) in 2
BC rivers? These deaths occurred during the summer when the sockeye salmon were returning

sturgeon eat many salmon at once, and this may be overloading their metabolic capacity during hot summers 😱

Sarah holds up an eel facts advent calendar in front of blooming flowers on her sidewalk. It says eel facts an advent calendar. It has 24 boxes with orange and yellow zigzags and yellow circles in the middle with numbers one through 24 in the middle of the boxes there are six eels depicted on this calendar, one green Moray, two splendid garden eels, one blue and yellow ribbon eel, and one American eel and one European.

This year we have sold 31% of the advent calendars that we sold last year 😓

The art is so pretty and colorful 🥺
The facts are so good 🥺
Eels are so cool 🥺

Get an eel facts advent calendar at EelFacts.net

digital drawing of a psychedelic house interior in a fisheye perspective. it has a vibrant but somehow musty color scheme. rooms intersect at impossible angles and some walls are missing, opening up to a huge black void. endless rooms and hallways fade into the distance.

i'll repost this forever i'm so proud of it

releasing these huuuuge sturgeon and watching them swim away is the best part of my job 🫶🏼

another week in the field complete, and one step closer to finding out what is harming these ancient fish 🧪👩🏻‍🔬🌎🌐🦑

Today my @nytimes.com colleagues and I are launching a new series called Lost Science. We interview US scientists who can no longer discover something new about our world, thanks to this year‘s cuts. Here is my first interview with a scientist who studied bees and fires. Gift link: nyti.ms/3IWXbiE
