Plants have different shaped leaves to cope with different environmental conditions. But many plants change the shape of their leaves over time and space! Why?
We can plant trees to re-establish a woodland community, but does planting trees help other elements of the community recover? What about the microbial community, it is responsible for much of the ecological functioning of intact ecosystems. Does restoration help the … Continue reading
A new global analysis looking at the distribution of forests and woodlands has ‘found’ 467 million hectares of previously unreported forest in dryland ecosystems – a land area equivalent to 60% of Australia. In this day and age of advanced … Continue reading
We may have been able to tame the dog – the only large carnivore to now happily coexist with humans. But how does domestication occur and can we learn from it to develop new animal breeds and crop varieties for … Continue reading
The secrets of the understudied Australian rangelands, which make up 81% of the continent, have been exposed in new scientific work
Since 1880, the average global temperature has increased by 0.8°℃, with large changes in rainfall redistribution. With these changing conditions upon us, and set to continue, gardeners will have to alter the way they do things.
Finding the optimum environment and avoiding uninhabitable conditions has been a challenge facing species throughout the history of life on Earth. But as the climate changes, many plants and animals are likely to find their favoured home much less hospitable.
A Devil’s Garden at Posada Amazonas (Keith Martin) Imagine you are hacking your way through the Amazon rainforest and you venture across a grove completely devoid of ground vegetation and dominated by a single tree species. A highly unusual occurrence … Continue reading
As Charles Darwin noted, the physical differences between individuals of a species are important for their future survival and success (or not). However there are also many not so obvious differences (known as cryptic variation) between individuals that give us important insights into the … Continue reading
Habitat clearance is threatening global biodiversity. In many places, isolated trees are all that remains of once extensive forest. So what happens to these trees and how can they survive in their new, highly modified environment without becoming the ‘living … Continue reading
