A few days ago, New Zealand’s Minister of Education announced the wider release of a resource on climate change, which was initially trialled at a Christchurch school during 2018. According to the Minister, children will learn about “the role science plays in understanding climate change, aids understanding of both the response to it and its impacts […]

(They’re not an isolated example; a range of parasites change their hosts’ behaviour. See here and here for example – though as you’ll find, […]
Continue readingI’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 […]
Continue readingPeople 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 […]
Continue readingMy 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, […]
Continue readingThe 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 […]
Continue readingA 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 […]
