Multiscale Trend Analysis for Pampa Grasslands Using Ground Data and Vegetation Sensor Imagery
This study aimed to evaluate changes in the aboveground net primary productivity (ANPP) of grasslands in the Pampa biome by using experimental plots and changes in the spectral responses of similar vegetation communities obtained by remote sensing and to compare both datasets with meteorological variations to validate the transition scales of the datasets. Two different geographic scales were c...
متن کاملSpider Trait Assembly Patterns and Resilience under Fire-Induced Vegetation Change in South Brazilian Grasslands
Disturbances induce changes on habitat proprieties that may filter organism's functional traits thereby shaping the structure and interactions of many trophic levels. We tested if communities of predators with foraging traits dependent on habitat structure respond to environmental change through cascades affecting the functional traits of plants. We monitored the response of spider and plant co...
متن کاملPeriodic versus scale-free patterns in dryland vegetation.
Two major forms of vegetation patterns have been observed in drylands: nearly periodic patterns with characteristic length scales, and amorphous, scale-free patterns with wide patch-size distributions. The emergence of scale-free patterns has been attributed to global competition over a limiting resource, but the physical and ecological origin of this phenomenon is not understood. Using a spati...
متن کاملPollen dispersal and breeding structure in a hawkmoth-pollinated Pampa grasslands species Petunia axillaris (Solanaceae).
BACKGROUND AND AIMS The evolution of selfing is one of the most common transitions in flowering plants, and this change in mating pattern has important systematic and ecological consequences because it often initiates reproductive isolation and speciation. Petunia axillaris (Solanaceae) includes three allopatric subspecies widely distributed in temperate South America that present different deg...
متن کاملManaging the effects of riparian vegetation on flooding
~ The major effect of removing riparian vegetation and wood from streams has been the changes in channel form (widening, deepening and straightening) that have occurred. It is important to consider that we are returning vegetation to a channel system that now has a much larger flow capacity. ~ The major hydrological effect of returning vegetation to streams is via its influence on roughness and...
