The NSW environment watchdog sat on a report for four years linking elevated levels of lead in children’s blood to current mining, and promised mining companies they would not do any “finger-pointing”, new documents tabled in state parliament show www.theguardian.com/australia-ne...
Environment watchdog buried report on lead in children’s blood to placate mining companies, emails show
Documents tabled in parliament show NSW agency took four years to publish report and told miners it would be put online ‘quietly’ but EPA says it was released to community earlier

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.

Check out our most recent publication in PNAS Nexus! 🦋👩‍🔬
Painted lady butterflies that migrate from Europe to the Mediterranean are not genetically distinct from those that migrate from Europe to West Africa. Instead, environmental cues likely determine migration distance. In PNAS Nexus: academic.oup.com/pnasnexus/ar...
Thank you again to my wonderful coauthors without whom this project would have been impossible: Daria Shipilina, Venkat Talla, Farid Bahleman, Khadim Kébé, Johanna Berger, Niclas Backström, Gerard Talavera, and Clément Bataille
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

Geometric morphometric analysis, accomplished by Johanna Berger and I, ultimately showing that the differences in migration distance could not be explained by wing size, wing shape, sex, or wing wear score
We performed whole-genome resequencing on our painted ladies. My co-lead author, Daria Shipilina, led the genomic analysis, with input from Venkat Talla, Niclas Backström, Gerard Talavera, and me. We found no genetic differentiation or population structure associated with migration distance
By applying hydrogen and strontium isotope geolocation, Clement Bataille and I confirmed distinct differences in migration distance – butterflies flew either long distances to sub-Saharan Africa – one over 4,000 km! - or short distances to the Mediterranean
First, Farid Bahleman and Khadim Kébé collected painted ladies south of the Sahara in the autumn. At the same time, Gerard Talavera and I collected painted ladies from the circum-Mediterranean region
