Prioritizing areas for conservation with phylogenetic diversity

Why is evolutionary history rarely considered in actual conservation planning? Well, there are many reasons. Conservation practitioners might not be aware that evolutionary diversity can be used in conservation. If they are aware, maybe it doesn’t compete with the vast number of other conservation concerns. Or maybe they do value it, and would like to use it, but are not sure how.

We have a new paper out in PhilTransRocSocB that addresses this last problem. We show how to use phylogenetic diversity in spatial prioritisation software. The advantage of using this software is that diversity can be considered alongside other concerns–extinction risk, connectivity, cost etc.

What do you need to do this?

1-distribution data (occurrence in grids or a species distribution model-SDM)

2-a phylogeny

How does it work?   Continue reading Prioritizing areas for conservation with phylogenetic diversity

Keeping the tree of life intact

How do we best preserve the world’s remaining biodiversity? That was the topic of a conference I attended last week at the Royal Society in London on ‘Phylogeny, extinction risk and conservation’.  The two-day conference included a range of interesting presentations on global to regional conservation efforts.

Obviously the extinction story can be a depressing one—the Yangtze River Dolphin is most likely extinct and one in five plant species are threatened with extinction. However, even given the looming threats to biodiversity, there is a huge effort underway to make informed decisions about how to prevent further losses.

Where in the landscape are the refugia?

Can you spot the refugia? Neither could we by looking, but genetic data suggests protected side-slopes

Locating areas where species will likely persist in future climate changes has recently become a conservation priority. How do we find these areas? A good first step is to look for places that species persisted through past climate changes (often termed ‘refugia’). We think we may have identified mini or micro-refugia for trees on deep, protected soils in the Grampians ranges, Victoria. Continue reading Where in the landscape are the refugia?
