Unveiling - Home

Our friends at the University of Florence have been looking into the aesthetic appeal of European butterflies and does this bias the species we choose to protect. You can help their research by completing a simple online survey. Many thanks in advance www.unveiling.eu?fbclid=IwZXh...

The #MountainPygmyPossum was first known only through the fossil record: some skull & jaw bones were found in 1895. Scientists believed the species must be extinct until 1966 when a living mountain pygmy possum was found. That’s a pretty secretive life!

In Australia, millions of newly hatched Bogong moths embark on an impressive journey twice a year.

A new study has found that the moths, with no parents to guide them, rely on bright stars and the Milky Way visible in the night sky to aid their migrations.

🚨 New Paper 🚨
Coauthors and I just published our work in PLOS One on Canadian graduate funding. We found that Canadian graduate funding falls _well_ below cost of living.
On average, $10kCAD below cost of living.

NEW PAPER: looking into the erosion of southern mountain caribou migrations. Over 35 years, migration distances shrank 15-25%, and elevational migrations are collapsing. Habitat loss, not weather, likely the main culprit. A major conservation challenge ahead.

So why do some painted ladies migrate across the Sahara while others don’t? Only future studies will be able to tell us for sure, but for now, we hypothesize that migration distance in painted ladies is a plastic response to environmental conditions, such as photoperiod

During the autumnal migration, some painted ladies migrate to the Mediterranean region, while others migrate across the Sahara to sub-Saharan Africa. Our question was, why do some painted ladies dare to cross the Sahara while others do not? Is the difference in behaviour genetically determined?

Every year, painted lady butterflies migrate between Europe and sub-Saharan Africa over a migratory cycle composed of 8 – 10 generations of butterflies. However, isotopes, pollen, monitoring data, and ecological niche modelling were all pointing to an interesting observation…
