Quantifying potential abiotic drivers of the ‘nurse plant effect’ in two dominant shrub species of the northern Chihuahuan Desert - Oecologia Aggregations of plants surrounded by sparsely vegetated areas in drylands can arise when larger plants facilitate the recruitment of smaller “protégé” plants—a phenomenon referred to as the “nurse plant” effect. Numerous drivers can generate a nurse plant effect; efforts to simultaneously quantify multiple drivers are rare. Given higher densities of protégés beneath the foundational shrubs Larrea tridentata and Neltuma glandulosa, multiple potential mechanisms underlying the nurse plant effect were quantified in the Chihuahuan Desert, New Mexico, USA. As expected, there was a greater concentration of soil nutrients and lower photosynthetically active radiation and soil temperatures beneath shrubs. Throughout the study, however, soil moisture was consistently higher in interspaces despite the greater water holding capacity of soils beneath shrubs. Nutrient concentrations were greater beneath N. glandulosa than L. tridentata, while protégé numbers did not significantly differ among the species. The canopy size of both species was positively related to understory shading, and the size of N. glandulosa was positively related to soil nitrogen and microbial biomass. The results of this study suggest that much of the abiotic nurse plant effect of this low-latitude system is explained by radiation interception and concomitant reductions in temperatures experienced by protégé plants as opposed to the direct effects of shrubs on soil water availability. As global change pressures intensify in drylands, a loss of perennial plant cover could have negative effects on soil biogeochemical pools and plant diversity. Quantification of the mechanisms driving the nurse plant effect across environmental and climatic gradients could improve our understanding of plant community dynamics in drylands.

Where can I find a reprint of this vintage Smokey's #mushroom poster? Found a store on Etsy, but the mushroom one is sold out 😭

Omg I was just saying this exa t same thing to a colleague this morning. also at least for me, waaaay less emails than in last semesters. At some point, I went into canvas to double check my announcements and modules were up 😅😅

Hey everybody! @drjuliawester.bsky.social and I have a new paper!

We surveyed over 800 scientists, science communicators, and science educators who use social media.

Conclusion: Scientists no longer find Twitter useful or pleasant, and many have switched to Bluesky! 🧪🌎🦑

We will keep investing #microbes (fungi and sometimes bacteria) under global change and looking at ecosystem-scale consequences 🍄🧫🦠🌎🧬

I'm grateful to my friends, colleagues, and students at NMSU 🌟

Thanks for the reminder @janemunday.bsky.social. Every summer, I repost this article DROWNING DOES NOT LOOK LIKE DROWNING. To date, I know of FOUR kids who were saved after someone who'd clicked on the link learnt how to spot actual drowning. Take time to read and pass on.

A group of semicircular shelf mushrooms with stripes on a log. Their centers are a reddish brown, and algae growing on them make them look partially green and yellow. They have some holes in them but they look eye-catching and colorful.

They look a bit worse for wear, but I was pleasantly surprised to find such colorful mushrooms on some random log in a parking lot!
