In Tasmania, the mines have closed but the rivers remember The King River snakes through some of Tasmania’s most dramatic and diverse landscape, flowing past rainforest, button grass plains and the rugged peaks of the West Coast Range before emptying into a…

side view of a male baridine weevil with two enormous, pointed, tusk-like spines arising from his prosternum.

my favorite figure from Eberhard and Garcia's 2000 paper on this behavior. It is captioned "Dorsal view of a horn-locking fight. The upper male has been tilted and his left rear and middle legs wave powerlessly in the air."

a little treat from the weevil mines, one of those baridine species where males have huge chest spines for "ritual jousting"

New Zealand’s critically endangered kākāpō is seeing one of its most successful breeding seasons in years, with 59 healthy chicks hatched to date.

While the total adult population has grown from a low of 51 in the 1990s to 236 today, low reproduction rates remain a hurdle.
