Getting them slightly moist, just stomping around some seeps for work! Pretty simple technique of walking around looking for gullies or other topography searching for seeps and using a small net and brush to pick out bugs. Apparently early spring is the best time, as the water table is high.

A man kneels down in a seep and turns over a log searching for crustaceans. He's surrounded by a small ravine cut through a hillside. A view looking out from the seep, showing a small patch of woods beside a park with recreational fields.

It doesn't even have to be in an untouched natural habitat either. This seep oozed out of a hillside below a road and adjacent to a recreational park.

An opaque white amphipod with long legs and antennae, lacking eyes. Smeagol from The Lord of the Rings holding the one ring in his hands.

Come on, just look at him. Little weirdo minding his own business in the groundwater and saturated interstitial soil spaces. Then during periods of high water tables the earth vomits him up through a seep, whence a most unlikely creature plucks him from the mucky leaves.

The Trump administration’s aggressive push for deep-sea mining is rapidly shaping up to be the defining ocean policy issue of this second term. I put a little primer over at LinkedIn, but here's a thread so you don't have to click through. www.linkedin.com/feed/update/... 🧵 1/4

So bummed to read this; I'm a huge fan of SimpleMappr. Whenever I needed a quick map to check species distributions or to plot some of my collections, I always turned to this site first.

If gender were the immutable biological reality they claim to believe it is, they wouldn't need to spend so much energy policing it like this.

An Army Corps project could wipe out one of Florida’s last thriving coral reefs The fate of one of the last thriving coral reefs in Florida may be imperiled by plans to widen the shipping channel leading into Port Everglades.

The US army corps of engineers is considering, right now, what would be the largest destruction of coral reefs in US history. To make a port slightly bigger.

People know this, right?

The discovery of a new “species” invariably leads to the discovery of new “species interactions” - new connections in the web of life. Here, the discovery of a new gall wasp also uncovered EIGHT new interactions with other insects - some likely new species as well. #biodiversity @ymilesz.bsky.social

“Almost all the 165 people killed in the attack were girls aged between seven and 12, according to local officials. There were around 170 girls at the school in southern Iran’s Minab at the time.“

I see the concentration camps are doing their jobs. This is their purpose, to warehouse and neglect, to kill with neglect.

The approximate cause of death for Anne Frank was the Nazis. The specific cause of death was the outbreak of Typhus at Bergen-Belsen camp, which overtook her (and others) from chronic malnutrition and medical abuse. These conditions are not, in character, unlike our system of immigration camps today

A flyer for Myriapod Meet-Up 2026. The flyer has a picture of a millipede on it. The millipede is tan and has a cone-shaped head.

Myriapod Meet Up 2026 will be on 1 April, 8AM - 5PM (EDT). This online event will include short talks, and a chance to share and discuss research about myriapods (and other multipedes, e.g. Onychophora). Anyone may participate in this free event (no need to give a talk).

Good article, but the framing is wrong. There is not a dearth of interest in taxonomy. There is a scarcity of funding and positions, which is a deliberate choice by funding agencies and institutions. The youth love taxonomy! It's the olds that are failing to meet their passion!

For months, @jacksonwryan.com has been looking into why so many video games sites have become full of gambling and casino stories, unusual author images, and, most recently, the use of AI. We've connected these sites to Clickout Media. Here's what we've learned.

A titan of vaccine development sees his field’s achievements slip away Stanley Plotkin, the 93-year-old "godfather of vaccines," is watching his field’s achievements slip away.

Stanley Plotkin had a major hand in the development of a number of vaccines in use today; he designed the rubella vaccine. He remembers the world before widespread use of vaccines & knows what's coming as vaccine policy is rewritten & vaccine confidence is eroded. www.statnews.com/2026/03/02/s...

Thanks for the tip. I've been working on figuring out Andrena to get through our backlog of specimens at Virginia Natural Heritage. Some of them make sense and others I'm putting off until later, but I'm enjoying the challenge.
