Data from: Shifts in woody plant defense syndromes during leaf development

1. Herbivores target young leaves in forests worldwide. How this strong and predictable selection pressure has shaped plant defense syndromes remains unclear. Specifically, whether young leaf herbivory has led to general global patterns of shifting leaf defences during lead development (i.e. ontogenetic trajectories) remains unknown but likely. 2. Using meta-analysis, we have synthesized developmental shifts in chemical, physical, and indirect defence traits, as well as leaf nutrient content, during leaf expansion and maturation across 124 woody plant species. Leaf traits were compared for immature young leaves versus mature leaves within studies, and these developmental shifts were then compared across studies to characterize general patterns. 3. Traits shifted strongly during leaf maturation, giving rise to discrete defence syndromes, with young leaves having significantly greater nutrient and secondary chemistry concentrations but reduced toughness and indirect defence traits than mature leaves. These patterns corroborate a growing consensus on the importance of ontogeny in plant defences, illustrating ontogenetic trajectories at the scale of leaves. 4. Trait developmental shifts were stronger in species with synchronous than asynchronous leaf flushing, but whether this reflects variation across biomes remains unclear. 5. Future research on under-studied traits, such as alkaloids, cyanogenesis, leaf phosphorus content, and indirect defence traits, and in a more biogeographic context will provide additional insights into the generality of shifts in defence syndromes during leaf development.

Data from: Woody plant biomass and carbon exchange depend on elephant-fire interactions across a productivity gradient in African savanna

Elephants and fire are individually well-known disturbance agents within savanna ecosystems, but their interactive role in governing tree-cover dynamics and savanna–forest biome boundaries remains unresolved. Of central importance are the mechanisms by which elephants vs. fire affect tree biomass and cover, and how – over long time periods – both factors interact with rainfall and soils to govern tree biomass and carbon dynamics. Here, we evaluated the response of woody vegetation to 56 years of fire manipulation in South Africa's Kruger National Park, with three fire regimes (annual, triennial and unburned) replicated across a productivity gradient and subject to two periods of contrasting elephant abundances (generated by the cessation of culling in 1994). Higher fire frequencies had a negative effect on woody biomass in the low-elephant period, but this effect was weak to negligible in the high-elephant period as the difference among fire treatments diminished. Moreover, elephants removed increasing amounts of woody biomass as productivity increased across study sites, but fire did not. We infer that elephant-induced tree mortality could overcome increases in woody-plant productivity, while fire-induced mortality alone could not. Elephants caused woody-plant carbon to shift from a sink to a source; this effect was independent of fire treatment, with highest rates of net carbon removal in the wettest and most productive site. Synthesis. Our results reveal a context-dependent interaction between fire and elephants as disturbance agents in savanna: the influence of fire on woody plants was sensitive to the abundance of elephants and diminished with increased plant productivity. In contrast, elephants were capable of shifting landscapes from relatively dense woodland to open savanna, even in unburned sites, and exerted strong impacts irrespective of site conditions and plant productivity.

Functional relationship between woody plants and insect communities in response to Bursaphelenchus xylophilus infestation in the Three Gorges Reservoir region

To study the effect of the invasion of Bursaphelenchus xylophilus on the functional relationship between woody plants and insect communities, the populations of tree species and insect communities were investigatived in the Masson pine forests with different infestation durations of B. xylophilus.

Data from: Geographical patterns in phylogenetic diversity of Chinese woody plants and its application for conservation planning

Aim: Biodiversity hotspots are widely used as conservation priorities to preserve the tree of life. However, many conservation practices identify biodiversity hotspots without considering phylogenetic diversity (PD), which reflects total evolutionary history and feature diversity of a region. Moreover, conservation planning rarely distinguishes between neo- and paleo-biodiversity hotspots despite their differences. Here, we 1) estimated large-scale patterns in PD of woody plants, 2) identified neo- and paleo-biodiversity hotspots, and 3) demonstrated their implication in conservation planning, with special focus on Hengduan Mountains and southern China. Location: China. Methods: Distributions of 11,405 woody species from the Atlas of Woody Plants in China were updated, and were transformed into a grid of 50 × 50 km2. By integrating distribution maps with a genus-level phylogeny of angiosperms, we estimated Faith's PD of each grid cell and evaluated the contribution of species relatedness to PD at given levels of species diversity (i.e. standardized PD, sPD) using regressions and three null models. Then we identified areas with significantly lower or higher sPD than expected as neo- and paleo-hotspots and estimated the coverage of protected areas in these regions. Results: Species diversity and PD decreased towards the north. Southern China had high species diversity, PD and sPD, while Hengduan Mountains had high species diversity and PD but low sPD. The coverage of protected areas in southern China was less than half of that in Hengduan Mountains and entire China. Main conclusions: Our results identified Hengduan Mountains as a neo-hotspot and southern China as a paleo-hotspot, highlighting their importance for biodiversity conservation. Compared to Hengduan Mountains, southern China has low coverage of protected areas, which calls for more conservation attention. Our study demonstrates a way of incorporating the phylogenetic component in the identification of neo- and paleo-hotspots, and hence of achieving a more complete perception of biodiversity patterns for conserving the tree of life.
