If the economy is so dependent on oil that it requires a war in the Middle East or some other devastating exogenous event to buoy oil prices and come closer to balancing budgets, maybe we're not making the best decisions.

Any Canadian tweeps recall what the GoC version of the OPERA Insar portal is? I can't locate it. @natural-resources.canada.ca

This happened at least twice in my memory when I was a member of the university's Academic Appeals committee. Can't remember which academic units were involved.

Also if your primary concern about the permanent time change is kids walking to school in the dark I present to you years of research showing school should start later in the day

I've looked at a lot of little red squiggling Chironomidae over the decades 🙂

those were different kinds of midges (Chironomidae) than what Art is referring to (Ceratopogonidae), but the principle (loss of taxonomists) is the same...

well, that was a bit of surprise (personally I was in favour of staying on standard time, but I guess I'm an outlier)

Creative inclusion or regressive exclusion? AI and the arms race in teaching and learning - CAUT As the workshop facilitator demonstrated the latest update in AI technology, we realized that we had lost the arms race of teaching and learning.

We had some thoughts about Generative AI, and @caut.bsky.social was kind enough to help us express them.

Margaret Sibella Brown stands beside a small wooden table, arranging flowers in a ceramic jug. She wears a long dark dress with fitted sleeves and a wide, ruffled white collar. Her hair is pinned up, and she looks down toward the bouquet of daisies and leaves in the jug. An open book rests on the table beside the vase. The photograph is sepia-toned with a plain backdrop.

Nova Scotia's Margaret Sibella Brown was fascinated with moss and liverworts.
As an amateur bryologist, she published several papers and oversaw efforts to collect sphagnum moss for use as surgical dressing during the First World War.
This is her story.

A photograph of a velvet worm: a segmented, soft-bodied animal, with beautiful patterning which looks like it has been rolled in orange and blue sequins.

A photograph of a giant springtail: an invertebrate with a soft blue body covered in long yellow soft spines.

Some exciting life news... I am now a lecturer in Entomology and Ecology at Lincoln University in NZ!

We took the Entomology students on a fieldtrip over the weekend, and saw some of my favourite invertebrates: Velvet worms and giant springtails! Always a treat to see these!

‘I love midges because I know what their hearts look like’: is the passion for taxonomy in danger of dying out? Insect taxonomist Art Borkent has described and named more than 300 species of midges but fears his field of science is dying out, despite millions of insects, fungi and other organisms waiting to be ...

Incredible article about Art Borkent, biting midges, and aging taxonomists.

I complain about CBC, because it’s not perfect, and fair criticism is allowed and appropriate. But seriously, thank God for CBC in Canada. It needs to be protected.

There was even a vial with an elaterid in amongst my mayfly vials. Don't think you'd be too interested, though, as it was a wireworm from the Ag station.

Very old ethanol. Some dark brown from a combo of bleeding from old stoppers & from the exoskeletons on the insects. All were examined in 80% ethanol & placed in clean vials with fresh 80% ethanol. The real work tho was deciphering the labels to make them readable! Most specimens were in good shape!

Vials contain from one to several dozen specimens, and these vials were opened, labels updated with georeferenced locality information, and identifications were updated as much as possible with current taxonomic information. These specimens will be returned to the Newfoundland Museum, The Rooms, for long term storage.

Big milestone day for me: finished curating ~1400 archived vials from several 1970s/80s collecting expeditions in Newfoundland & Labrador. Result: >15,000 specimens & 66 species of mayfly. Breakdown: 63 from Labrador, 25 from Isl. of Newfoundland; 25 in common. 37 genera represented, in 12 families.

The pictured ones were from archived samples from Newfoundland & Labrador so I didn't collect them. I have collected them from fast moving streams in New Brunswick though - just a normal Hess sampler with 200um mesh for larvae, and emergence traps for adults.

They were common in a small stream I worked on in New Brunswick (Canada) many years back, but I hadn't encountered any since then, so this was a real treat!

a pair of mating Nymphomyia walkeri adults. These tiny little flies would have feathery wings when they first emerge, but lose their wings when they re-enter the water to mate.

A larva of Nymphomyia walkeri from Newfoundland. This is a tiny little white worm-like larva with a shiny head and little prolegs all along the abdomen.

Dorsal view of a Blepharicera tenuipes larva from Labrador, Canada. The larvae is a pale tan in colour, with a darker mark on its head. Each segment is expanded out on each side, with a proleg on each side.

Ventral view of a Blepharicera tenuipes larva from Labrador, Canada. The larvae is a pale tan in colour, and each segment is expanded, with a dark, circular sucker in the centre to help the larva hold on to rocks in fast water. Little finger-like gills can also be seen on each segment.

Quite a treat to encounter some cute little Diptera in vials inadvertently included amongst my Newfoundland and Labrador mayfly vials: these are Nymphomyiids and blepharicerids.
