Helen Taylor

Helen Taylor is a conservation genetics researcher at the University of Otago in Dunedin. She is interested in what happens to the genetics of populations when they get very small, and how factors like loss of genetic diversity and increased inbreeding might affect species’ persistence via impacts on their reproductive success and survival. Helen’s research mainly focusses on threatened birds. In New Zealand, she has focused on little spotted kiwi, South Island robin, and hihi (or stitchbird), but she has also worked with threatened birds in Europe and the Peruvian Amazon. Helen’s time is currently split between remote islands around the country, and the lab/office in Dunedin. You can track her down on twitter @HelenTaylorCG

De-extinction: more hype than hope - Wild Science

Mar 08, 2017

Efforts to resurrect extinct species could divert funding away from conserving extant species, but a more basic issue with “de-extinction” is the misinformation surrounding the topic. A recent study by New Zealand and Australian researchers puts a price on “de-extinction”. The team also estimate how many native extant species might be lost by directing these funds away from existing conservation efforts. (Read more about this on the Sciblogs News blog). The take home message is that “de-extinction” could come at the cost of preserving native species. An excellent point, but this is only one problem with the quest to revive long-dead lineages. “De-extinction” is not actually a thing “De-extinction”: an overused and highly misleading term The very word “de-extinction” encapsulates perhaps the biggest misconception around talk about bringing back moa and mammoths. The word conjures up Jurassic Park-like … Read More

Get ready for CRISPR conservation - Wild Science

Feb 09, 2017

New Zealand is known for its bold, proactive conservation strategies. Are we ready to use advanced gene editing techniques to save native species? Imagine being able to turn genes on and off, or change their code and alter their function. This is the reality of gene editing technologies facilitated by enzymes like CRISPR-Cas9. CRISPR is essentially a pair of molecular scissors. These scissors can be programmed to target a particular stretch of DNA and then modify it in any of the ways described above. Gene editing has obvious implications for human health. Unsurprisingly, the idea and now practice of editing the genes of human embryos has generated considerable controversy. No less controversial is the idea of using CRISPR for conservation. As a new paper points out, conservation scientists and practitioners need to engage with gene … Read More

‘Conservation by numbers’ hides genetic dangers in endangered species - Wild Science

Jan 18, 2017

How do we know when a threatened species is ‘safe’? A new study featuring one of New Zealand’s iconic kiwi species suggests increasing population size might not be enough – an increase in numbers doesn’t always cut it for conservation… Saving threatened species tends to be a numbers game. We often use population growth as a proxy for population security. The more individuals of a given species exist, the less endangered we perceive that species to be. Population size and growth/decline are the major criteria for deciding how a species is classified on the IUCN Red List – arguably the most influential international ranking of threatened species. But what happens when the numbers are misleading? What if population growth hides damaging factors that could threaten the future persistence of a species? Kiwi hiding inbreeding depression A little spotted … Read More
