Plants, their predators, and early warning systems - BioBlog

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 out that their responses to the … Read More

Christopher M. Berry, Cardiff University This article was originally published on The Conversation. Read the original article. Imagine a world without trees, and then try to think about the changes that would need to happen for these trees to evolve from the small primitive plants that came before them. I spend as much time as I … Read More

Danica-Lea Larcombe, Edith Cowan University The number of Australians living in high-rise apartments doubled between 1991 and 2011 and that trend has continued since then. The quarter-acre dream is fast disappearing and larger blocks and family gardens along with it. As more people move from country areas to the city and as land to build homes near … Read More

Local extinctions: Climate change’s vanishing trick - News

Now you see them, now you don’t. Hundreds of species have already undergone ‘local extinctions’ because of climate change, according to new a study. As overall temperatures increase around the world thanks to climate change, plants and animals are starting to shift their geographic range closer to the cooler poles of the planet, or higher up the slopes of mountains.

A couple of days ago I did a spot of live radio with the good folks at 95bFM. It was great fun. One of the topics was dog evolution, which I’ve already written about here; another was the recent publications on human dispersal, covered nicely over on sciblogs.co.nz.  The third was a brief discussion of claims made … Read More

The pollinating power of the humble honeybee is worth millions of dollars to the New Zealand agricultural sector – but we are at risk of losing it. Bees are having a hard time of it these days; varroa mite, pesticides and a lack of plant diversity are all contributing to the decline of the bee populations crucial for pollinating crops.

While I madly tackle the pre-Christmas to-do list (sigh) I’d like to give a shout-out to a blog post by Glenn Stewart,  Professor of Urban Ecology, Lincoln University (near Christchurch), about what is happening to gardens in ‘abandoned’ Christchurch homes. As you might expect, they’re growing wild, with a natural succession taking place that is … Read More

Plants in the water cycle - Waiology

• water cycle,
• Waterscape

By Daniel Collins When you think about hydrology, the first things that come to mind are often rain and rivers, not plants. But plants have a significant effect on how much rain actually reaches the rivers. We see this most readily in the reduction in river flow when grassland is replaced by shrubland or forest. Low flows, mean flow and … Read More

Friday video: not on the Ark – (intelligent* and interesting) plants - Code for life

• plants,
• video

Stefano Mancuso’s TED lecture, shown below, opens with him pointing out what he considers to be the biggest error in the story of Noah’s ark – there were no plants.** I immediately thought: ’nor fungi’, then ’nor bacteria’ (which is a bit unfair as the writers of that day couldn’t see them). I then thought of viruses, … Read More
