Breaking news: giant springtail from Aotearoa NZ made the cover of @natecoevo.nature.com!

This amazing pic of H. paucispinosa by @frankashwood.bsky.social should lure readers to the global study by @zheng-zhou.bsky.social et al on soil animal trophic diversity 🌍🌿🕷️🪱🪳🧪

Fig. 1. The relationship between mean shoot length per grass species to species richness of the endophytic insects found in these shoots.

A The number of herbivore species, B the sum of herbivore and parasitoid species. The five points indicating no species at all indicate that no one insect species has been reared from the five annual grass species studied, despite intensive shoot sampling (see Table 1). The inquilines of P. australis are included (see Table 2, see also Fig. S2A and S2B for regressions without inquilines). Regression lines were fitted to the species richness found in the ten perennial grass species.

Longer shoots host richer herbivore–parasitoid communities. Unmown refuges are key to protecting these overlooked specialists. 🕷️

University administration sent me an email yesterday, inviting me to come to the office today to finalize everything. Now they just cancelled the appointment and told me they can't employ me anymore. Who treats people like this?? #IchBinHanna

New paper alert! Microclimate temperatures are more extreme than we previously thought! Near-ground temperatures are amplified in hot weather, cool refugia is lost and replaced with heat traps ☀️🔥🥵 escape from heat will be very hard for small ground-dwelling organisms

Hypothesised scaling relationships between body size and population density and energy use (metabolism and energy flux) for predators and secondary consumers

Hypothesised scaling relationships between body size and population density and energy use (metabolism and energy flux) for predators and secondary consumers

❗New paper alert❗
The 2nd publication from Poppy Romera's Masters is just out in @natcomms.nature.com
We find that adherence of 180 soil food webs to the energy equivalence rule strongly depends on the measure of energy use, trophic level, and food web structure. www.nature.com/articles/s41...
