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 🌍 🧪

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.

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.

Megafire severity, fire frequency and their interactions with habitat affect post-fire responses of small mammal and reptile species

Climate change is driving extreme fires in many ecosystems around the world. There is an urgent need to understand how co-occurring and interacting th…

#Newarticle Hickman et al.’s long-term study finds that alpine summit vegetation responds multi-directionally to different, co-occurring drivers, with outcomes contingent on life history characteristics: doi.org/10.1080/15230430.2024.2429864
