New Perspective paper is out! We reviewed how eDNA is currently used for biodiversity monitoring in Southeast Asia and developed recommendations to strengthen its regional application.

Our paper is out, focusing on design, validation, and implementation considerations for species-targeted eRNA assays to detect presence and physiological state! Some new ideas to ponder.

What happens *after* enemy release? In a new paper, we present 7 years of infection & immune trait dynamics in 16 lake populations of stickleback.

This is definitely the longest-scale study I've done in my career, I'm very excited to see it out.

Migratory freshwater fish are in steep decline due to pressures along their paths, including dams, altered flows, habitat degradation, pollution and unsustainable fishing.
Restoring rivers and habitats cannot wait.

Less dams, more fish! 🐟🏞️
Restoring rivers and habitats cannot wait.
i made a sparkly moon mug in honor of the incredible scientific feat NASA astronauts are undertaking today 🌕 🌙💫

a large sturgeon in the Fraser river held by a smiling Madison on the nose and Chris on the tail. you can see the sturgeons face clearly highlighting the size of the nose and eyes
happy #sturgeonsaturday (on sunday)! 🧪👩🏻🔬🌐🦑🌎
did you know that sturgeon rely heavily on scent & feel to find food rather than eyesight?
in the photo you can see the barbels (like whiskers) & the 2 nostrils - which are basically the same size as the eye!
these strong sniffers are quite impressive 👃

i mixed my two most frequent pastimes: worrying & pottery, with my love for the sea 🫶🏼
i always need to fidget with things, these are a sensory dream with a smooth & rougher side and i love them sm :)

happy #sturgeonsaturday !
this is the time of year that sturgeon wake up from their overwintering cuddling and move around in search of food!
in the Fraser River, BC this usually aligns with the eulachon spawning run, a crucial sturgeon food source, full of fat after a long winter 🍽️

wanna follow a suuuper cool group of people leading a variety of conservation efforts???
look no further!!!
@libererofellows.bsky.social starter pack is here 🤩
🧪👩🏻🔬🦑🐟🌐🌎
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

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!
new paper and illustrations 🧪👩🏻🔬🌎🌐
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

Ooooh. Cool new paper on origins of life. A simple 45-nucleotide RNA molecule that can perfectly copy itself.

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
👩🏻🔬🧪🌎🍒🫐🐚💫
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

What’s happening on the Bathurst calving grounds?
We found strong spatiotemporal overlap between grizzlies and caribou during calving, highlighting potential risk during this sensitive period. Deeply grateful to the collaborators who made this work possible!

Thanks Jim, much appreciated!
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
PSF scientists, led by @wbuggiii.bsky.social, recently published a research breakthrough on identifying food deprivation in wild salmon.

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 😱

Wildlife deserves more than minimum viable populations.
Conservation should aim for ecosystems where species can thrive, not just survive. 💥🦬🌲

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 🧪👩🏻🔬🌎🌐🦑
