Ever grateful to those that speak up & out, & for their solidarity.

Science suppression & self-censorship is rife. I understand why many are reluctant to speak truth to power, it can come with great costs, seen & unseen, with the latter often being the most insidious, upsetting & damaging. #ESA2025

Fab talk from @megcevans.bsky.social about government trying to use capitalism (for profit model) to attempt to solve problems created by capitalism (environmental damage and biodiversity loss).
But $2bn to solve biodiversity crisis isn't much compared to many other publicly funded things.

Some fantastic tips on engaging with the media coming from hugely experienced @biodivcouncil.bsky.social Jaana Dielenberg and Claire Peddie @ecolsocaus.bsky.social #ESA2025

- short, clear and fun pitches
- prep photos/videos ahead of time
- say yes to radio & tv to expand your audience

The motto of #ESA2025 this year is "Biodiversity on the brink – BOLD ACTIONS for a resilient future"

On Thu I'm presenting on a super bold, landscape-scale biodiversity project that will keep 10-25 species from being added to Threatened species list.

Thu 1030!
Big room!
Comfy chairs!
Great photos!

ARC are considering a restructure in which jobs there will be lost, a source tells me.

This seems ridiculous when they're about to completely overhaul the entire grants system – they've never undertaken anything so large before!

I've long said ARC needs MANY MORE staff, & should do more, not less.

As EPBC reforms get framed as political tussles & deal-making, don't forget ongoing colonialism, what's at stake on Indigenous lands, and their warnings that bad amendments & inadequate environmental laws "risk irreversible damage to country, culture and communities"

We have no answers from our institutions as to why Go8 universities endorsed BCA's regressive EPBC recommendations

But 90 of us have signed an 'Independent statement on the Group of Eight’s position on EPBC Act reforms'

🙏 Prof Justine Bell-James for writing & coordinating the independent statement
Independent statement on the Group of Eight’s position on EPBC Act reforms The federal Parliament is currently considering amendments to the flagship federal environmental legislation, the Environment Protection and Biodiversity Conservation Act 1999 (‘EPBC Act’). This is a once-in-a-generation opportunity to strengthen environmental protections to reverse Australia’s current trajectory of extinctions and biodiversity loss. We are academics at the institutions in the Group of Eight (Go8), with expertise in biodiversity conservation science, climate science, policy, economics and law. We support amendments to the EPBC Act to strengthen protections for biodiversity and remove ministerial discretion and legal loopholes, in order to create a level playing field for businesses, and make environmental protection and recovery central to all decision-making processes under the Act. We note that the Go8 has signed a statement by the Business Council of Australia endorsing amendments that will weaken the Act’s protection for the environment. This statement does not reflect the world leading conservation research being carried out at our institutions. It also does not reflect the extensive evidence-based advice provided by experts based at Go8 institutions during the review and consultation processes over the past five years. We disagree with this statement, and the Go8’s endorsement of it.

A Scarlet Kingsnake (Lampropeltis elapsoides) from NE Louisiana. These small (<24in) kingsnakes are mimics of the venomous Eastern Coral Snake (Micrurus fulvius) and a joy to photograph. #herps #snakes #NaturePhotography 🌿
Side image of a brightly colored snake, posed on a leaf and facing right. The front quarter of the snake is in the image, the body starting at lower right to middle left where it curves back to the right, with the head and neck in an S-shaped curve. The snake is a banded tricolor, as follows a wide red band, followed by a narrow black band, then a wider white band, another narrow black band, and then repeat. The neck and upper and lower jaws are white, while the top of the head and the nose are red.
