Seedling growth declines in warmed tropical forest soils
Biotropica, Volume 55, Issue 5, Page 897-910, September 2023., 2023 The response of tropical forest plants to a warming climate could have a large feedback on further climatic change. To address this, we tested the response of six tree species seedlings to 3 years of in‐situ experimental soil warming. Our study demonstrates that belowground warming causes species‐specific declines in the growth and photosynthesis of ...

Journal of Ecology, Volume 111, Issue 6, Page 1218-1230, June 2023., 2023 Our results demonstrate that soil nutrient‐based species selection is a prevalent driver of community assembly in tropical forests, a process mediated by key functional traits within the leaf and wood economics spectrum. Functional space size and its filling increase with soil nutrient concentration, whereas niche vacancy decreases.

No home‐field advantage in litter decomposition from the desert to temperate forest
Functional Ecology, Volume 37, Issue 5, Page 1315-1327, May 2023., 2023 Read the free Plain Language Summary for this article on the Journal blog. Abstract Litter decomposition rates are determined by the interplay of climate, decomposer organisms and litter quality. It has been suggested that the decomposer community may be locally adapted to litter quality, providing a home‐field advantage (HFA) resulting in accelerated ...

Biocrusts increase the resistance to warming‐induced increases in topsoil P pools
Journal of Ecology, Volume 110, Issue 9, Page 2074-2087, September 2022., 2022 Our findings provide novel insights on the responses of soil P pools to warming and rainfall reduction, and highlight the importance of biocrusts as modulators of these responses in dryland ecosystems. Our results suggest that the observed negative impacts of warming on dryland biocrust communities will decrease their capacity to buffer changes in ...

Functional Ecology, Volume 36, Issue 8, Page 1858-1872, August 2022., 2022 Read the free Plain Language Summary for this article on the Journal blog. Abstract Variation in leaf functional traits along environmental gradients can reveal how vascular epiphytes respond to broad‐ and small‐scale environmental gradients. Along elevational gradients, both temperature and precipitation likely play an important role as drivers of ...

Journal of Ecology, Volume 110, Issue 2, Page 430-442, February 2022., 2022 The effect of rare phytoplankton species losses on ecosystem functioning can be compensated by the persistent species when nutrient ratios are uniform, but leads to a decrease in ecosystem functioning under variable nutrient ratios. Abstract Positive biodiversity–ecosystem functioning (BEF) relationships are predicted to increase in strength when high ...

Fisheries management influences phytoplankton biomass of Amazonian floodplain lakes
Journal of Applied Ecology, Volume 58, Issue 4, Page 731-743, April 2021., 2021 Tropical freshwaters fisheries typically assume that fish biomass is controlled by bottom‐up mechanisms, so that overexploitation of large predators would not affect overall ecosystem productivity. Our results, however, show that top‐down forces are important drivers of primary productivity in tropical lakes, above and beyond the effects of bottom‐up ...

Functional Ecology, Volume 34, Issue 2, Page 442-457, February 2020., 2020 A free Plain Language Summary can be found within the Supporting Information of this article. Abstract Plant growth on harsh substrates (habitat specialization) requires specific traits to cope with stressful conditions. We tested whether traits related to nutrient acquisition (root colonization by fungal symbionts, and plant morphological and ...
