“…Numerous wild mammal species have been extirpated locally but low densities of Northern Red Muntjac ( Muntiacus vaginalis ), Reeves's Muntjac ( Muntiacus reevesi ), Wild Boar ( Sus scrofa ), and Dwarf Musk Deer ( Moschus berezovskii ) remain (Gu et al, 2022). Cows have been present in the landscape for over 2000 years (Cremin, 2010) and goats were introduced <20 years ago (personal communication). Presently, the dominant mammalian herbivores at Yubaiding are about 924 free‐ranging cattle and 5016 goats in an area of about 69 km 2 (data from Administration of Forestry and Grassland of Yuxi), representing a low to moderate grazing intensity (Gu et al, 2022).…”

Leaf chemistry of architecturally defended plants responds more strongly to soil phosphorus variation than non‐architecturally defended ones

Plants utilize a mixture of defence types in response to herbivores, including physical, chemical, and biological defences. Among chemical defences, phenolics are well‐known to inhibit digestion and are highly variable across plant species and resource gradients. There are prominent hypotheses predicting the potential change of phenolics in response to soil nutrients, but most focus on nitrogen (N) and none consider their interaction with defence strategies. We proposed an updated theoretical model that incorporates defence types and predicts their relative advantages under herbivore attack. We studied intraspecific leaf chemistry of several architecturally defended and non‐architecturally defended species growing together across four sites with varying soil chemistry. We measured individual‐level leaf concentrations of carbon, nitrogen, phosphorus (P), potassium (K), and phenolics, and site‐level soil N, P, and K. We found that architectural defenders had lower phenolics and higher P than non‐architectural defenders across locations. Relationships between soil nutrients and leaf chemistry were steeper in architectural defenders. Most leaf nutrients and phenolics showed significant relationships with soil P, and only leaf P was related to its respective soil resource. Within leaves, phenolics were negatively related to leaf N in both groups but only negatively related to leaf P for architectural defenders. Our results suggest that architectural defenders are less able to accumulate phenolic defences in high P soils than non‐architectural defender. One possible explanation is that phenolic production is limited in P‐rich soils via active phloem loading, but only in architectural defenders that have defence options other than chemical ones.
