Quite a few years ago I was the project officer managing a remnant vegetation protection project and was having a phone interview with a newspaper journalist. The newspaper had agreed to write a featured article in exchange for a paid advertisement for the project.

The journalist asked me about the project and I explained about fencing and revegetating land next to the original remnant vegetation, remnant from before European settlement, to protect and buffer the remnant from threats. …

A 40 horse power tractor with a 28-kilowatt hour battery, providing 4 to 8 hours of operation, is available for around USD$45,000. The difference in operation time depends on whether the ‘power take off’ PTO is being used to run other machinery. This size tractor is suited to small farms, vineyards and parks and gardens and would be particularly useful in glasshouse operations. Solectrac eUtility eUtility Electric Tractor — Solectrac

The popular fastener hook and loop tape, or Velcro from the French for velvet velours and hook crochet, is a well-used example of biomimicry, of technological inventers mimicking biology or copying nature. Velcro’s attachment mimics the hooks on the seed capsules of the Burdock burr plant.

There is much to learn from the natural world and this has been demonstrated on the website Biomimicry 3.8, named after the 3.8 billion years organisms have developed their survival mechanisms.

Biomimicry 3.8 is a network of scientists, engineers, architects and designers who share successful biomimicry ideas (Biomimicry, 2021; Miller & Spoolman, 2016).

Marine protected areas, MPAs, conserve shark populations by restricting fishing and protecting their habitats, if they are suitably located. Australia has had MPAs for eighty years and has one of the largest networks of MPAs. Well enforced, large, no-take MPAs of suitable habitat are needed to conserve shark species.

Climate change and the resulting ocean warming is threatening the suitability of shark habitat and MPAs.

Oceans absorb 90% of the heat held in by anthropogenic greenhouse gases which results in increasing ocean temperatures. Such changes may affect sharks as they reach the upper limit of their body temperature range. …

Two Wedge-tailed Eagles circled a grazing mob of kangaroos, they had selected one young adult male to attack and dived at it. The kangaroo was about 1.2metres tall.

The Eagles separated this one kangaroo from the mob and started repeatedly striking the animal, taking it in turns, climbing to 20 to 30metres and then rapidly diving at the animal, striking at its head with talons and buffeting the head with their wings.

Strikes on the kangaroo were occurring every 15 seconds, with visible wounds to the head and…
