In mountainous regions, climate warming is expected to shift species' ranges higher altitudes. Evidence for such shifts still mostly from revisitations of historical sites. We present recent (2001 2008) changes in vascular plant species richness observed a standardized monitoring network across Europe's major mountain ranges. Species have moved upslope on average. However, these had opposite effects the summit floras' boreal-temperate regions (+3.9 average) and Mediterranean (-1.4 species),...
We combined two existing datasets of vegetation aboveground biomass (AGB) (Proceedings the National Academy Sciences United States America, 108, 2011, 9899; Nature Climate Change, 2, 2012, 182) into a pan-tropical AGB map at 1-km resolution using an independent reference dataset field observations and locally calibrated high-resolution maps, harmonized upscaled to 14 477 estimates. Our data fusion approach uses bias removal weighted linear averaging that incorporates spatializes patterns...
Summary The aim of this study was to document patterns in tree reproductive phenology a rain forest central Borneo and examine relationships between climatic patterns. A 10‐year data set (1990–2000) monthly observations flowering fruit production 171 trees (including 39 members the Dipterocarpaceae) at Barito Ulu, Central Kalimantan, Indonesia, showed that most (73%) underwent activity on supra‐annual timescale. There were three general (GF) events, 1991, 1994 1997, which preceded by major...
Less than half of anthropogenic carbon dioxide emissions remain in the atmosphere. While balance models imply large uptake tropical forests, direct on-the-ground observations are still lacking Southeast Asia. Here, using long-term plot monitoring records up to a century, we find that intact forests Borneo gained 0.43 Mg C ha-1 per year (95% CI 0.14-0.72, mean period 1988-2010) above-ground live biomass. These results closely match those from African and Amazonian networks, suggesting world's...

We assessed extent to which aspect its relatedness temperature affect species diversity, colonization disappearance of on summits a pan‐European scale. Location Mountain in Europe's zone.

Abstract Quantifying the relationship between tree diameter and height is a key component of efforts to estimate biomass carbon stocks in tropical forests. Although substantial site‐to‐site variation height–diameter allometries has been documented, time consuming nature measuring all heights an inventory plot means that most studies do not include height, or else use generic pan‐tropical regional allometric equations height. Using dataset 73 plots where at least 150 trees had in‐field...
Abstract Climate change threatens the role of European forests as a long-term carbon sink. Assisted migration aims to increase resilience forest tree populations climate change, using species-specific climatic limits and local adaptations through transferring seed provenances. We modelled assisted scenarios for seven main species analysed effects provenance selection, accounting environmental genetic variations, on annual above-ground sink regrowing juvenile forests. To resilience,...
1 The stress gradient hypothesis suggests a shift from predominant competition to facilitation along gradients of increasing environmental severity. This is proposed cause parallel changes prevailing spatial segregation aggregation among the species within community. 2 We used 904 1-m2 plots, each subdivided into 100 10 × cm, or 25 20 cm cells, respectively, 67 European mountain summits grouped 18 regional altitudinal transects, test this hypothesized correlation between fine-scale patterns...
The natural distribution, habitat, growth and evolutionary history of tree species are strongly dependent on ecological genetic processes in ecosystems subject to fluctuating climatic conditions, but there have been few experimental comparisons sensitivity between species. We compared the responses two broadleaved (Fagus sylvatica Quercus petraea) conifer (Pinus sylvestris Picea abies) transfers by fitting models containing same variables. used published data from European provenance test...
Abstract Fragmented tropical forest landscapes preserve much of the remaining biodiversity and carbon stocks. Climate change is expected to intensify droughts increase fire hazard intensities, thereby causing habitat deterioration, losses stock losses. Understanding trajectories that these may follow under increased climate pressure imperative for establishing strategies conservation ecosystem services. Here, we used a quantitative predictive modelling approach project spatial distribution...
A nutrient addition experiment was set up in August 1993 a species–rich primary lowland dipterocarp forest Barito Ulu, Central Kalimantan, Indonesia. The following treatments were applied: control, +N, +P and +NP. There five blocks of four 50 m times plots with separate treatment for each plot. Fine litterfall measured on all the from l May 1994 12 months. Litterfall mass phosphorus concentrations significantly higher fertilizer compared controls. All trees (greater than or equal to 10 cm...
High-elevation valleys in dry areas of the Himalayas are among most extreme, yet least explored environments on Earth. These barren, rocky subjected to year-round temperature fluctuations across freezing point and very low availability water nutrients, causing previous workers hypothesize that no photoautotrophic life (primary producers) exists these locations. However, there has been work using modern biogeochemical or culture-independent molecular methods test hypothesis photoautotrophs...
Most tropical evergreen rain forests are characterised by varying degrees of precipitation seasonality that influence plant phenology and litterfall dynamics. Soil microbes sensitive to soil water:air ratio nutrient availability. We studied if within-year in litterfall-derived input resulted predictable seasonal variation bacterial diversity/microbial functional groups an Amazonian forest. the spatio-temporal dynamics microbial communities from plot stand scales related them spatial...
Abstract Microbiota are essential components of the soil, driving biogeochemical cycles. Fungi affect decomposition and biotic interactions with plants across scales. Climate projections suggest that extended dry seasons may transform sensitive rain forests into savanna-like vegetation, consequent changes in biogeochemistry. Here we compare impacts natural seasonality 14 years partial throughfall exclusion an Amazonian forest, focussing on soil fungal functional diversity, extracellular...
