Quantifying aboveground herbaceous biomass in grassy ecosystems: a comparison of field and high‐resolution UAV‐LiDAR approaches

open access: yesRemote Sensing in Ecology and Conservation
Grassy ecosystems cover >25% of the world's land surface area. The abundance of herbaceous vegetation in these systems directly impacts a variety of ecological processes, including carbon sequestration, regulation of water and nutrient cycling, and ...

Are they two seeds in a pod? Comparing seed rain recovery in grasslands using artificial grass carpets versus sticky traps

open access: yesApplications in Plant Sciences
Premise Seed dispersal is a critical process for plant community assembly; however, natural rates of seed arrival are rarely quantified compared with other assembly mechanisms, especially in herbaceous communities.

Population structure of Calyptranthes clusiifolia O.Berg in two patches in the southerN Minas Gerais state

open access: yesBioscience Journal, 2014
This work intended to study the structure of two populations of Calyptranthes clusiifolia in two patches of Semidecidual Seasonal Forest in different anthropic conditions. In each patch we established transections where all the individuals of the species

Implications of Liebig’s law of the minimum for tree-ring reconstructions of climate

open access: yesEnvironmental Research Letters, 2017
A basic principle of ecology, known as Liebig’s Law of the Minimum, is that plant growth reflects the strongest limiting environmental factor. This principle implies that a limiting environmental factor can be inferred from historical growth and, in ...

Volatile Organic Compounds Emitted by Flowers: Ecological Roles, Production by Plants, Extraction, and Identification

open access: yesPlants
Volatile organic compounds (VOCs) with a large chemical diversity are emitted by plant flowers. These compounds play an important role in the ecology of plants.

Siplab, a spatial individual-based plant modelling system [PDF]

open access: yesComputational Ecology and Software, 2014
Spatially-explicit individual-based models are important tools in forestry and plant ecology. They are commonly implemented through custom computer coding that is time-consuming, may cause compatibility and availability problems, and makes difficult the ...

Invariant Spatial Pattern Across Mediterranean Scrublands in the Iberian Pear (Pyrus bourgaeana)

open access: yesEcology and Evolution
The spatial distribution pattern of plant species is frequently driven by a combination of biotic and abiotic factors that jointly influence the arrival, establishment, and reproduction of plants.
