The Cat Act is being reviewed in Western Australia, public comment is open. Next week the WA Feral Cat Working Group will be publishing our guidance on the changes needed to improve responsible pet cat ownership in Western Australia. We encourage you to use our guidance to shape your submission!

With cross-party support and a recognition of urgency, the inexplicable stalling of the WA Cat Act Amendment Bill is concerning. Please prioritise this bill and get it through, for the sake of all creatures great and small.

Why has the Cat Act Amendment Bill stalled in the WA parliament? It is certainly not because it is lacking bipartisan support and widespread recognition that the issue is an urgent priority. Let’s get this done. #bioinvasions

Quotes from WA state politicians that show bipartisan support for the Cat Amendment (Local Laws) Bill in Western Australia

What does the fourth dimension of plant resource allocation mean for weed biocontrol? In a #newpaper, we propose a framework for quantifying how gall-inducing insects impact the G-R-D tradeoff & review the species that can contribute to effective biocontrol. 🌏🌐#BioInvasions Read the 📖: rdcu.be/fpbBL

A framework for establishing the impacts on plant fitness via reprioritization of available resources in response to classical bio-logical management. Impacts of biocontrol agents on host plants are depicted pre-agent (red sphere,  T0) and post-agent (blue spheres,  T1) exposure. For plants hosting non-gall-inducing agents (a,  b), finite plant resources (area of the triangle) are optimally partitioned between growth (G), reproduction (R), and defence (D) to maximise plant fitness. Note, overall plant tolerance (T) is optimized by varying investment over the D–G axis. Non-gall-inducing agents can impact negatively on fitness by either shifting investment away from growth and/or reproduction (a) or by reducing the plant’s overall resources (b). For host plants with gall-inducing agents (c,  d), finite plant resources (area of the pyramid), and in turn fitness, are additionally impacted through diversion of plant resources into the gall tissue sink (S), with response and counter-response between the agent and host driving investment partitioning toward and along the D–S axis (blue arrows)

"If people really knew the depth of the calamity facing us, they would demand more from their leaders at every level. ... It’s a host of accelerating, interconnected issues that together are creating a deeply unsustainable trajectory for our world." 🌐 paulhardistyauthor.substack.com/p/if-you-wan...

If you want to understand what’s really happening today, follow the money.

Greenwashing schools. Coal over coral. Frightened boards and captured leaders. The deep duplicity preventing the fundamental change we need.

David Attenborough has been an inspiration to my family for four generations. His ability to craft a message has brought the natural world to billions of people. Happy 100th birthday Sir David! Thank you for helping us to realise what an incredible planet we have and need to keep fighting for. ❤️

Europe spent years debating whether the energy transition was affordable. Spain quietly answered the question: gas now sets its electricity price in only 7% of hours. Strategic autonomy doesn’t arrive via summit communiqués. It’s built in advance — in wind farms, solar parks, and grid investment

An avoidable cat-astrophe in Western Australia. Every month ~800 pet cats and ~4M birds, mammals & reptiles die because current policy prevents pet cats from being contained. This paper reveals broad support for change: 78% of local govts want containment laws. Let's get this done. #bioinvasions 🌐🌏

Feral cats and foxes really have driven many Australian mammals to extinction. Claims these introduced predators aren't responsible don't stack up. Protecting our unique species will be even harder if feral cats and foxes are given a free pass to keep killing. 🌐🌎 theconversation.com/yes-feral-ca...

Yes, feral cats and foxes really have driven many Australian mammals to extinction

Decades of evidence link foxes and feral cats with extinctions of Australian mammals. Claims these introduced predators aren’t responsible don’t stack up.
