Inferring trait-based mechanisms and variance consequences of abiotic secondary dispersal from the spatio-temporal distribution of a desert soil seed bank
(Wiley Blackwell Publishing, Inc, 2021-01)
Questions: Quantifying the combined effects of seed traits, microsite types, and abiotic dispersal agents on the mean and variance of seed bank density and composition will help understand vegetation dynamics in deserts. ...
Species-specific influences of shrubs on the non-dormant soil seed bank of native and exotic plant species in central-northern Monte Desert
(Wiley, 2012-03)
Deserts shrubs are well known to facilitate vegetation aggregation, mostly through seed trapping, and stress amelioration during and after plant establishment. Because vegetation aggregation effects are a by-product of ...
Bioleft: open-source seeds for low-input farming systems
(Pluto Journals, 2020-06-01)
This article describes Bioleft, an ‘open source’, highly collaborative seed breeding initiative, in order to encourage reflection on potential synergies with fair trade ideas and practices. Bioleft aims to develop and ...
Climate niche mismatch and the collapse of primate seed dispersal services in the Amazon
(2020-07-01)
Animal-plant interactions are threatened by ongoing climate change, deforestation, and defaunation. The disruption of biotic interactions leads to loss of ecosystem services but estimates of the magnitude of reductions are ...
Retention and redistribution of biological legacies generate resource sinks in silvopastoral systems of Arid Chaco forests
(Springer Verlag Berlín, 2019-07-11)
Background: Forests are used for multiple purposes worldwide, which often include timber harvest, firewood extraction and livestock raising. An excessive pressure on multipurpose systems may decrease soil cover, promoting ...

Overland flow from plant patches: coupled effects of preferential infiltration, surface roughness and depression storage at the semiarid Patagonian Monte
(Elsevier Science, 2016-02)
The objective of this study is to characterize and quantify the overland flow generated from the plant patch areas of spotted vegetation towards the immediate surrounding bare ground including the coupled effects of ...
Climate change reshapes the eco-evolutionary dynamics of a Neotropical seed dispersal system
(2021-05-01)
Aim: Global changes will redistribute biodiversity, reshaping ecological interactions and ecosystem processes. The decoupling in the distribution of plants and their mutualistic seed dispersers, for instance, may have ...
Composição química e suplementação mineral em sementes de soja: qualidade fisiológica, desenvolvimento de plântulas e aspectos produtivos
(Universidade Federal de Santa MariaBRAgronomiaUFSMPrograma de Pós-Graduação em Agronomia, 2016-03-29)
Soybean is the main aleuro oleaginous cultivated in the world and are used for several ends such as human and animal food and biofuel. Nevertheless, the productivity is still below the productive potential. Among the ...
Degradation and recovery processes in semi-arid patchy rangelands of northern Patagonia, Argentina
(Wiley, 2013-08)
Vegetation in many arid and semiarid shrublands is frequently arranged in patches with high plant-cover (shrub patches) interspersed in a low-cover herbaceous matrix (inter-shrub areas). We hypothesized that (a) livestock ...
