In this study, we experimentally show that stochasticity can play prominent roles in driving local species assembly in annual plant‐dominated communities of semiarid gypsum ecosystems. Drylands are traditionally viewed as restrictive environments that impose strong deterministic filtering effects, but neutral events can also contribute decisively to ...

Mechanism of 2003, 2007 and 2009 earthquakes (S. Vicente Cape) and implications for the 1755 Lisbon earthquake [PDF]
The San Vicente Cape region (SW Iberia) is of great seismological interest due to its tectonic complexity and for the occurrence of the 1755 Lisbon mega-earthquake.

ABSTRACT Plant‐hummingbird interaction networks can be influenced by environmental conditions and resources, which vary seasonally and daily. We aimed to understand how variations in these parameters across these two temporal windows influence patterns of plant‐hummingbird interactions and hummingbirds dominance hierarchies in a Brazilian Cerrado ...

Focal Mechanism and Rupture Process of 2004 Alhoceima (Morocco, Mw=6.2) Earthquake from Teleseismic and Regional Broad-Band Data. [PDF]
We have study the focal mechanism of the 2004 Alhoceima (Morocco, Mw=6.2) earthquake using teleseismic and regional broad-band data. The solution obtained shows strike slip motion with planes striking respectively on NNE-SSW and WNW-ESE direction and ...

New Metallicities of RR Lyrae Stars in omega Centauri: Evidence for a Non He-Enhanced Metal-Intermediate Population [PDF]
We present new spectroscopic metal abundances for 74 RR Lyrae stars in omega Cen obtained with FLAMES. The well-known metallicity spread is visible among the RR Lyrae variables.

Graphical abstract summarizing the modelling experiments used to quantify streamflow elasticity to changes and temporal redistribution of precipitation across South America, highlighting stronger effects of seasonal redistribution and larger responses in humid climates. ABSTRACT This study examines the sensitivity of mean, high and low streamflows (i.e.
