Feral horse damage in a subalpine grassland on Bogong High Plains; autumn 2019 (left) and autumn 2025 (right). Recovery from disturbances in alpine systems is slow - but a marked change in condition since horses were remove! Perennial snow grasses and native forbs beginning to colonise bare ground.

New paper out on the impacts of fire on 5 small vertebrates across SE Australia. High severity fire has a substantial impact on threatened broad-toothed rats and glossy grass skinks. We also highlight the importance of habitat refuges for ameliorating impacts of recurrent fires.

New paper, led by @dadriscoll.bsky.social. • High fire severity caused precipitous declines of two threatened species. • Protecting or creating refuges is critical to counter increasingly frequent fires. www.sciencedirect.com/science/arti...

Yayy 🌱🪲🐝🐌- A list of stellar ecologists and myself showed that (1) species interactions can be summarised at the guild level, except for a few critical species, (2) they occur along a continuum from positive-to-negative, and (3) they have relatively weak strength except between plants!

A Continuum From Positive to Negative Interactions Drives Plant Species' Performance in a Diverse Community

We explored the patterns of species performance in a real-world community, dependent on pairwise and higher-order interactions with species belonging to the same and other trophic levels (plant, herb....
