Vegetation phenology in temperate grasslands is highly sensitive to climate change. However, it is still unclear how the timing of vegetation phenology events (especially for autumn phenology) is altered in response to climate change across different grassland types. In this study, we investigated variations of the growing season start (SOS) and end (EOS), derived from Moderate Resolution Imagi...

Hypogene caves in the Plavecký hradný vrch Hill (Western Slovakia, Central Europe) were formed by waters ascending along faults fractured Triassic carbonates related to horst-graben structure at contact of Malé Karpaty Mountains and NE part Vienna Basin. The Plavecká jaskyňa Pec mostly contain horizontal passages chambers with flat corrosion bedrock floors, fissure discharge feeders, wall water...

Drought is a complex phenomenon which can be characterised mainly by its severity, duration and areal extent. Among these three dimensions, drought severity is the key factor which can be used for drought analysis. Drought indices are typically used to assess drought severity in a meaningful way. DrinC (Drought Indices Calculator) is a software package which was developed for providing a simple...

Dryland plant ecosystems tend to exhibit bistable dynamics with two preferential configurations of bare and vegetated soils. Climate fluctuations are usually believed to act as a source of disturbance on these ecosystems and to reduce their stability and resilience. In contrast, this work shows that random interannual fluctuations of precipitation may lead to the emergence of an intermediate st...

High spatial and spectral resolution refl ectance data acquired by the Mars Reconnaissance Orbiter Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) instrument reveal the presence of H2Oand SiOH-bearing phases on the Martian surface. The spectra are most consistent with opaline silica and glass altered to various degrees, confi rming predictions based on geochemical experiments and m...

Worldwide estimate of acid sulfate soils is 12–14 million ha. In Malaysia, they occur mainly along the coastal plains of Peninsular Malaysia and Sarawak. The soils are characterized by very low pH and high amounts of exchangeable Al, resulting from oxidation of pyrite when the soils are drained. This paper explains the transformation of pyrite when the soils undergo weathering due to drainage. ...

The influence of sodium chloride on dissolution of chalcopyrite and surface sulfur speciation during bioleaching of chalcopyrite with the extreme thermophile Acidianus manzaensis YN-25 was studied. The addition of sodium chloride accelerated the dissolution of chalcopyrite by reducing the accumulation of elemental sulfur layers on the mineral surface, resulting in an increase in the concentrati...
