[LINK] “Jumping Spiders Can Think Ahead, Plan Detours”

National Geographic‘s Michael Greshko notes the unusual intelligence of a certain kind of predatory spider. (Beautiful pictures, if you’re into this.)

With brains the size of a sesame seed, jumping spiders may seem like mental lightweights.

But a new study shows that many species plan out intricate detours to reach their prey—smarts usually associated with far bigger creatures.

The arachnids, already well known for their colors and elaborate mating rituals, have sharp vision and an impressive awareness of three-dimensional space.

“Their vision is more on par with vertebrates,” says Damian Elias of the University of California, Berkeley, who wasn’t involved in the new research. “And that allows them to do things that are physically impossible for other animals that size.”

Jumping spiders of the subfamily Spartaeinae (spar-TAY-in-ay) are particularly ambitious—they eat other spiders. Researchers suspect that preying on other predators requires extra intelligence and cunning.

[URBAN NOTE] On Toronto’s early spring being more like early summer

Toronto’s weather today–21 degrees Celsius and shining–is record-breaking.

Environment Canada is predicting a high of 23 C at Pearson International Airport’s weather station and similar temperatures for the rest of the region.

The temperature will be a bit cooler closer to Lake Ontario, with the high expected to be more like 16 C, Environment Canada said.

Record high temperatures have already been set at 23 weather stations in Ontario, including Cobourg, Collingwood, Goderich, Sudbury, Hamilton Munro Airport, Toronto Buttonville and Wiarton, said CP24 meteorologist Bill Coulter.

On Wednesday night, the temperature will dip to a low of 13 C, but it is expected to soar to 26 C on Thursday, when more records will likely be shattered.

A rare March heat wave is giving Torontonians a break from usual March weather – normal highs of 6 C and lows of -3 C – and setting records almost daily with summer-like temperatures.

Speaking about a heat wave the way CP24 just did is misleading, inasmuch as the entire winter has been absurdly warm. This is uncharted territory for Torontonians, with wholesale changes to the entire year’s environment upcoming. Insect ecologies, for instance, will be radically changed, some species doing better thanks to the early warming and others worse.

What will become of the Toronto climate, this year and in following years? I wonder; I fear, even.
