I’ve learned quite a bit about spiders over the years. (And I have never been able to understand the “burn it with fire!” some folks take towards these 8-legged creatures.) For example, it turns out that some spiders actively hunt fish, while others are vegetarian! Then, late last year, I came across a couple of […]

People tend to think that plants don’t do much from day to day – certainly when I asked my first-year students at the start of the course, they were far more interested in animals than in plants. Poor plants! But then, to the casual eye I guess they’re fairly static creatures 🙂 However, it turns […]

My interest in kākāpō way back in my honours year at uni: a guest speaker told us that as far as anybody knew, the last remaining birds were a few males, somewhere in Fiordland. I remember feeling that that sounded really sad – those lonely males booming for females who never came. Shortly after that, […]

The news that school students from across New Zealand are organising the School Strike for Climate on March 15 has been all over the media lately. See this story, for example, which includes the comment that Globally, their message is clear. They are sick of waiting for adults to save their world so they are […]

A substantial proportion of the CO2 we release into the atmosphere, via burning fossil fuels, ends up dissolved in the ocean. The impact of this is a change in the ocean’s acidity: the pH drops. According to the Smithsonian, oceans have become substantially more acidic over the last 200 years (the period of the Industrial […]
Continue readingToday a science-minded friend posted a screenshot of a post by another individual to the FB group 1080 eyewitness. Because it is a) heavy on the innuendo, b) inaccurate, and c) decidedly unpleasant, I thought it worthy of a bit of additional attention. Let’s look at c) first. The original poster claimed to have written […]
Continue readingPangolins are strange little creatures, with their diet of ants and termites, and the entire outer surface of their bodies covered with armour-like scales (face, belly & the inner surfaces of the limbs are either hairy or naked). When in danger, pangolins are able to roll up in a ball, presenting only that armoured surface […]
Continue readingStudents often get to look at hydras – tiny, fresh-water members of the group that includes sea anemones, jellyfish, corals, and the Portuguese man’o’war. All these cnidarians have a simple body-plan: two layers of true tissue with a jelly-like layer between them, a sac-like gut with a single opening that acts as both mouth and […]
Continue readingTomtits and robins were the focus of the first question in the 2016 Schol Bio paper. Specifically, Chatham Island tomtits and robins, which are found only on the Chathams. While at one point they were common and widespread on the islands, the tomtit is classified as nationally endangered, while the black robin is nationally critical […]
Continue readingLike probably everyone reading this, I have always thought that spiders are carnivorous, sucking the precious bodily fluidsA from their prey. I mean, those fangs! And I was wrong, for it seems that some spiders eat some plant material alongside their liquid meals – and some are almost fully vegetarian. A just-published paper (Painting, Nicholson, […]
