If you are in the Portland (OR) area, I will be giving a talk this week at PSU on the tropical-temperate forest ecotone in Bhutan. Thursday 10/9, 3:30-4:25, Cramer Hall room 53. Open to the public. #Bhutan #biogeography #Rhododendron #ecotone #forest #ecology #Himalayas #PDX #mountains

Been busy writing, apologies for my hermit-like tendencies as of late.

Showing off our figure of global conifer leaf-widths & leaf silhouettes highlighting that conifers can be broad-leaved & angiosperms can be narrow/ needle-leaved! 🍃 Our paper: tinyurl.com/mss2me7v @newphyt.bsky.social @vallicrosah.bsky.social @botanykat.bsky.social & Matilda Brown

There are 2 previous historical cases of countries destroying their science and universities, crippling them for decades: Lysenkoism in the USSR and Nazi Germany. The Trump administration will be the 3rd. It's not just budgets but research, institutions, expertise, and training the next generation.

Oldest known fossil evidence of lepidopterans (butterflies & moths), from the Triassic (~236 mya) of Argentina! Scales from the wings of these insects were preserved in dicynodont coprolites, & were likely on plants eaten by the dicynodonts. www.science.org/content/arti... #PoopScience 🧪💩🪨🦋

Interested in #OpenScience, #reproducibility, #FAIRdata, #GBIF, #biodiversity data, and #AI? In November, we are organizing a course for early career ecologists in the home of the reindeer! 🌱🏔️🐑🦌🦋🦇🐞🌾💻 www.uib.no/en/rg/EECRG/...

I was sitting quietly in the forest this morning, watching a Royal Flycatcher nest when this wonderful Keel-billed Motmot perched near me for a few minutes. These are one of the toughest motmots. They're quiet, small, and love the dark forest. At @tapirvalley.bsky.social #costarica #birds #nature

Any tips for writing in the summer? Nice days outside, yet computer time awaits. I miss the rain.

Another hOUwie pondering @omearabrian.bsky.social... when choosing factors, does it matter if there is strong vs weak phylogenetic signal (Pagel's lambda or Blomberg's k)? My continuous factor has a lambda close to zero, would this cause problems? The signal for the discrete character is unknown/TBD

Really excited to say that my lab's paper on color transitions in Mimulus sect. Erythranthe is out! We found that some traits demonstrate evolutionary convergence in phenotype & genotype, while others are divergent, & that - as Bob Vickery found - bees prefer yellow! www.nature.com/articles/s41...

Yet another #hOUwie question @omearabrian.bsky.social does the program work via changing or reconstructing the branching of the tree (but keeping discrete tips constant) or is it the other way around (keep the tree constant but shuffle the discrete tips)?

Old-growth, fire-resistant Douglas-firs marked for logging as part of the Paul's Payoff timber sale, on the BLM's Medford District (sw Oregon). Square this w/the agency's official statement that "they don't log old-growth"...?

Spring is here! (Well some places not quite VT) We’re getting 2025 observations for our Pollinator Interactions on Plants project! We know much more about herbaceous flowers than we do tree flowers but trees are incredible floral resources! Watch your trees and submit data to help us learn more!

The people who produce this Mauna Loa atmospheric CO₂ record have a lab in Hilo, Hawaiʻi, about 50 miles (80 km) from the observatory. By closing the lab, it'll be really difficult to maintain the CO₂ observations.

Fully funded PhD in Plant Ecophysiology at UBC in Vancouver 🍁! Possible topics include leaf physiology, thermal ecology, microclimates, scaling, tree physiology, forest ecology & more. Start Jan/May/Sept 2026. michaletzlab.org Please share! #PlantEcoPhys #Ecology #Botany #PhDposition #GradSchool

I am wrapping my head around how hOUwie works, is it essentially Pagel's test for cor. evolution but with three traits (two discrete traits plus one continuous one)? Does it also differ based on added bells and whistles (e.g. allowing for differences in rate of evolution)? @omearabrian.bsky.social

Phylogenetic relationships & repeated loss of traits associated with #sicklebill #pollination in Centropogon subgenus Centropogon New #AJB research by Janet Mansaray, Ana Bedoya, Laura Frost, Olivia Degreenia & Laura Lagomarsino bsapubs.onlinelibrary.wiley.com/doi/10.1002/... #botany #plantscience

Barriers to dispersal are key to understanding biogeography, the pattern of life across the planet. Here Daniel Field explains Wallace’s line using Wallace’s actual specimen of greater bird-of paradise. youtu.be/L_FQ4tYkVoY?...

Anyone know where I can find a super big gigantic list of all nectarivorous bird species, spanning from Malaysia to PNG? My added wish-list bonus would be any natural history observations of flower species visited, or maybe photos of beaks w/ a scale bar #sunbird #honeyeater #lorikeet #flowerpecker

I'll be presenting my work on tree growth in an everwet forest in Puerto Rico at the ForestGEO seminar next week! Mar 19, 2025 09:00 AM, EST time. Register here for the link: smithsonian.zoom.us/meeting/regi...

Ghost pipe flowers I have met Monotropa uniflora is a parasitic plant and utterly enchanting.

Reminding myself to enjoy spring, the scent of red current flowers, pink of cherry blossoms, random clusters of crocus in purple yellow white.

THIS IS HUGE! Researchers at Stanford University have developed a dual-antibody treatment that remains effective against ALL SARS-CoV-2 variants by targeting a less-mutable part of the virus. This breakthrough could lead to longer-lasting therapies that OUTPACE viral evolution. 🧪🧵⬇️

An analysis of forest plant traits from across the tropical Americas suggests that forests are not changing fast enough to keep up with #ClimateChange. Learn more in this week's issue of Science: scim.ag/3QLYhyc

Tropical forests are not all the same: they show many shades of geographical variation. Our new paper in Nature led by @jeaggu.bsky.social combines field and satellite data to make a first map the canopy functional traits of the world’s tropical forests: www.nature.com/articles/s41...

Taking inspiration from stress-tolerant flora. Defy the conditions where other plants wither; thrive despite toxic or barren conditions; grow tough f*ck-off leaves; disappear and then serendipitously resurrect; find nourishment via strategic partnerships or outright carnivory; be unique to survive.

The scaly-foot snail doesn’t bow to pressure—it thrives under it. Living in toxic hydrothermal vents, it armors itself with iron, turning the very forces that should destroy it into protection. That’s how you resist oppression—adapt, fortify, and endure. 🐌🔥 #MolluscMonday #Resist

Some examples of research USGS does that is at risk with RIFs and restructuring: - earth quake and volcano monitoring and warnings - landslide risk assessments - water quality testing - wildlife conservation - wildfire prevention and post-fire rehabilitation - invasive species tracking

"Public investment" vs "Wasteful Subsidy." The only problem with this clever Singer cartoon is that some people might actually not get that it’s sarcastically illustrating the incorrect perception problem, NOT telling the truth. Just in case it actually needs to be said, the truth is the opposite.

#Pinguicula laueana “CalCarn Red” and “Tangerine” represent two color variants of the scarlet-flowered butterwort endemic to Oaxaca, Mexico. Like many plants with tubular red flowers, this one is visited by hummingbirds, though observations of this behavior are rare. #Butterwort #carnivorousPlant

We are hiring a seasonal research intern to work in our Bur Oak ACE experiment at The Morton Arboretum. Our lab is a fun group, the experiment fascinating. Come join us! Application: careers.hireology.com/themortonarb... ... information: www.wbez.org/race-class-c... grist.org/science/to-u...

Of the 4000 researchers at NIH, only 20% are tenured. They’re going to fire all the rest as their contracts come up for renewal, absolutely decimating research at the NIH. This is catastrophic, not just for Americans, but for the whole world. www.science.org/content/arti...

All probationary federal employees at NOAA’s EMC that’s responsible for keeping all US weather model systems running have been fired with 1 hours notice. And that includes me and colleagues. We will not go quietly because we care about the NOAA mission to protect the public.
