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.

Creative inclusion orΒ 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.

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.

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!

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!
