Characterisation of Drought and Wet Events in the Paraíba do Sul River Basin—Brazil
International Journal of Climatology, EarlyView.Trend analysis identified statistically significant reductions in precipitation (at the 5% significance level) at specific pluviometric stations in São Paulo and Rio de Janeiro, while other areas, mainly in Minas Gerais, experienced significant increases in annual and seasonal rainfall, particularly during summer and spring. These significant trends at

Manual of tropical bryology [PDF]
, 2003 Bryophytes belong to the oldest land plants. They existed already in the Palaeozoic 300 mio years ago in forms which were hardly different from the extant species. They remained relatively unchanged with relatively low evolution rates (and are thus often

Rare earth elements as tracers of chemical transfer processes in tropical rain forest soils in french Guiana : S13.04-P -10 [PDF]
, 2012 The rare earth elements (REE) have been successfully used in the past to trace weathering and water/rock interaction in lateritic soil systems. In the present study we used the REE to monitor chemical transfer processes in French Guiana along a ...
