🔥🌿We simulated heatwaves on alpine plant communities at Mt Hotham, Australia, and found no effect on survival, diversity, or reproduction. Heat alone might not be the main threat, as high rainfall may have helped plants tolerate heat stress. 📄 doi.org/10.1016/j.ec...

Nice way to wrap up 2025 🎓🌱 Published the final paper from my PhD! Across Europe & Australia, we found that common leaf defence traits don’t predict enemy release in introduced plants. A reminder that invasion success may hinge on factors we’re still missing. 📄 link.springer.com/article/10.1...

A striking orchid flower with green and burgundy petals and a distinctive dark red-brown labellum (lip) covered in fine, hair-like projections. The flower grows on a slender green stem among tall grass-like foliage, with a soft, blurred natural background.

📖Published📖 Arnold et al. propose a design that will allow ecologists to simulate more realistic heat events in the field by combining a controllable convection heater system with a semi-enclosed chamber with adjustable vents 🌍 🧪 buff.ly/k2GJSA2
Images of the chamber and active heating system. (a) Annotated detail image of the heating system, electrical components, and chambers (not to scale). Field photos from Mt. Hotham, VIC, Australia (Case study 1): (b) two polycarbonate chambers attached via black ducting to one heating system under a tarpaulin for protection from the weather; and (c) side view of a chamber with its semi-enclosed, overhanging lid with adjustable portholes, circulating fans, and Stevenson screen housing thermocouples. (d) Field photo from Perisher Valley, NSW, Australia (Case study 2). The heating system attached to three chambers showing improved insulative ducting and open tent protecting and ventilating the heating system. Note that chamber lids are transparent like the chamber sides but appear grey due to reflections of cloud cover.

Removing institutional barriers to long-term fieldwork is critical for advancing ecology
Long-term fieldwork is essential for ecology and conservation, but is hindered by institutional barriers, such as the publish-or-perish culture of academia, and funding limitations. Here, we discuss these challenges and propose strategies to overcome them, such as broadening evaluation metrics and supporting inclusivity, to advance scientific insight and societal equity.

Long-term data is critical for understanding how ecosystems work and how they might look in the future. But it's getting harder and harder to do due to funding limitations. We need to prioritise this sort of research and to stop cutting funding for it.
