10 years of Citation.js 10 years ago, on September 28th, 2015, I pushed the first commit of “C [1] ”, which would later form the basis of Citation.js . Back then, ...

One of my first open sources projects, Citation.js (citation.js.org), turns 10 years old today!

Wow, I had no idea it was so much less common in the UK

Houdt 'verbeteren' hier ook in dat de onafgeronde coördinaten in GBIF komen? Dat zou tof zijn!

Disproportionately High Contribution of Ditches to Landscape Greenhouse Gas Emissions in Drained Peatlands - Ecosystems Drained peatlands are a significant source of greenhouse gas (GHG) emissions; however, research has predominantly focused on terrestrial areas, with much less attention given to drainage ditches. Desp...

There have been some busy bees 🍯in the department!

Judith van der Knaap and colleagues published a paper in Ecosystems about the contribution of drainage ditches to greenhouse gas emissions in drained peatlands here in the Netherlands.

Next, we will look at if and when invasive species are covered by such keys.

Library of Identification Resources: a FAIR overview of taxonomic keys Biodiversity is declining globally, and ecological research is key to monitor and counteract this decline. Such research requires the taxonomic identification of organisms by both professional and cit...

Our paper on the Library of Identification Resources is out! In it, we describe how and why to record publications for the taxonomic identification of organisms in a FAIR database, and how to query that data to find applicable resources for an insect or a plant in NW Europe.

Flower-filled dikes attract bees: ‘Dikes are insect highways’ | Radboud University A large census conducted on 157 dikes along rivers in the Netherlands revealed that more and rarer bee species live on dikes than previously thought.

A large census conducted on 157 dikes along rivers in the Netherlands revealed that more and rarer bee species live on dikes than previously thought. According to ecologist Constant Swinkels, many more dikes can be made bee-friendly. #bees #science #ecology #dikes www.ru.nl/en/research/...

Standing tall together: Peatland vascular plants facilitate Sphagnum moss microtopography To preserve the heterogenic and diverse nature of peatland ecosystems, a well-functioning plant community is imperative. In intact peat bogs, such com…

Paper alert!

PhD student Yvet Telgenkamp and colleagues measured Sphagnum carpet subsidence in a long-term vascular plant removal experiment at Store Mosse National Park in Sweden. They found that vascular plants provide scaffolding for Sphagnum moss.

Did budget cuts play a role? No. In this particular case, we have seen absolutely nothing to suggest that current staffing or budget issues within NOAA and the NWS played any role at all in this event. Anyone using this event to claim that is being dishonest. There are many places you can go with expressing thoughts on the current and proposed cuts. We've been very vocal about them here. But this is not the right event for those takes. In fact, weather balloon launches played a vital role in forecast messaging on Thursday night as the event was beginning to unfold. If you want to go that route, use this event as a symbol of the value NOAA and NWS bring to society, understanding that as horrific as this is, yes, it could always have been even worse.

A useful deep dive on the forecasts here. theeyewall.substack.com/p/making-sen...

Wonderful!

In an unconscionable decision, the Smithsonian Institute has decided to no longer support the Biodiversity Heritage Library from 1 Jan 2026. Please someone step up and take it over.

5 male Lasioglossum male mining bees roosting on buttercup seed heads.

7 male Lassioglossum males roosting on stems of and seedheads on buttercup plants.

A patch of unmown lawn in a garden in Shrewsbury, UK. A roost of up to 18 males has built up here today - 29 June 2025.

Absolutely superb! I have a roost of Lasioglossum cf calceatum males in my garden. Maximum count so far 18. It's warm so thet are skittish and photographing them is hard. They have been building in numbers since about 16:30 hrs. This is just the best! Will give regular updates as it happens.

Diamond-shaped yellow bug with brown stripes on a metal pole.

Round brown bug with a light brown abdomen, on grass seeds.

Brown bug nymph with red and black stripes.

Brownish black bug with vague brown markings on a white net.

While sweeping I also found the aforementioned Aelia acuminata, nymphs of Eurygaster testudinaria, both associated with grasses, and nymphs and adults of the seed bug Peritrechus geniculatus.

Closeup of a small brown bug with lighter dots and a central line, and a wide, flat face. On a white net.

Found a species of shield bug I hadn't seen before, Neottiglossa pusilla! Related to Aelia and also found on grasses.

you can drop the 🍞🍍| right?
