TL;DR: Investigation of seasonal photosynthetic patterns in three European oak species exposed in lysimeter-based open-top chambers to elevated daytime temperature and drought shows that European oaks may benefit from elevated temperature, but detrimental effects can be expected when elevated temperature occurs simultaneously with drought.
Abstract: Oaks are commonly considered as drought- and heat-tolerant trees that might benefit from a warmer and drier climate. Their tolerance to drought has been frequently studied in the past, whereas studies dealing with elevated temperature or its combination with drought are very limited in number. In this study we investigated seasonal photosynthetic patterns in three European oak species (Quercus robur, Q. petraea, Q. pubescens) exposed in lysimeter-based open-top chambers (OTC) to elevated daytime temperature, drought and their combination. Stomatal and nonstomatal traits of photosynthesis were followed over an entire growing season and related to changes in daytime temperature, soil moisture and pre-dawn leaf water potential (WPD). Elevated daytime temperature enhanced net photosynthesis (PN )i n a season-dependent manner, with higher mid-summer rates than in controls exposed to ambient temperature. Drought imposed in early and mid-summer reduced the soil moisture content and caused a gradual decline in WPD, stomatal conductance (gS) and PN. Drought effects on WPD and PN were exacerbated when drought was combined with elevated daytime temperature. In general, PN tended to be more affected by low soil moisture content or low WPD in Q. robur than in Q. petraea and Q. pubescens. Non-stomatal limitations may have contributed to the drought-induced decline of PN in Q. robur, as indicated by a down-regulation of PSII photochemistry (FV ⁄FM) and decreased chlorophyll content. Taken together, our findings show that European oaks may benefit from elevated temperature, but detrimental effects can be expected when elevated temperature occurs simultaneously with drought.

TL;DR: While some EcM fungi species did not survive heating, the majority of species was also found in the heated samples, and the most frequent species in the heat treatment were Rhizopogon roseolus, Cenococcum geophilum and several unidentified species.

TL;DR: In this article, the authors calculate mineral-specific chemical weathering rates at two field sites in the Rio Icacos catchment, Puerto Rico, by combining new mineral abundance measurements from quantitative powder X-ray diffraction (XRD) with existing measurements of soil production rates from cosmogenic nuclides, chemical alteration of the regolith from Xray fluorescence (XRF), and dust deposition rates.

TL;DR: The results suggested that both sludge amendments significantly improved soil properties, however, the CIS amendment was relatively more effective in restoring soil functions and effectively immobilizing wastewater derived heavy metals compared to FIS treatment.

TL;DR: It is shown that peatland species occur in two distinct clusters, and functional identity and redundancy was maintained under taxonomic turnover, which may allow these peat bogs to maintain ecosystem functioning when subject to future environmental change.
Abstract: In peatland ecosystems, plant communities mediate a globally significant carbon store. The effects of global environmental change on plant assemblages are expected to be a factor in determining how ecosystem functions such as carbon uptake will respond. Using vegetation data from 56 Sphagnum-dominated peat bogs across Europe, we show that in these ecosystems plant species aggregate into two major clusters that are each defined by shared response to environmental conditions. Across environmental gradients, we find significant taxonomic turnover in both clusters. However, functional identity and functional redundancy of the community as a whole remain unchanged. This strongly suggests that in peat bogs, species turnover across environmental gradients is restricted to functionally similar species. Our results demonstrate that plant taxonomic and functional turnover are decoupled, which may allow these peat bogs to maintain ecosystem functioning when subject to future environmental change.
