Spatial validation reveals poor predictive performance of large-scale ecological mapping models
Nature Communications, 2020 Mapping ecological variables using machine-learning algorithms based on remote-sensing data has become a widespread practice in ecology. Here, the authors use forest biomass mapping as a study case to show that the most common model validation approach ...

, 2014 We propose here to interpret and model peculiar plant morphologies (cushions, tussocks) observed in the Andean altiplano as localized structures. Such structures resulting in a patchy, aperiodic aspect of the vegetation cover are hypothesized to self ...

Shifts in leaf litter breakdown along a forestpastureurban gradient in Andean streams [PDF]
, 2016 Tropical montane ecosystems of the Andes are critically threatened by a rapid land-use change which can potentially affect stream variables, aquatic communities, and ecosystem processes such as leaf litter breakdown.

The Influence of Land Consolidation on Biomass and Ecological Environment
Research Journal of Applied Sciences, Engineering and Technology, 2014 Land consolidation changes the land use types and then the biomass. The measure and calculation of biomass fore-and-aft land consolidation worked out by the sample plot method in terms of arbor, shrub, herbage plants and crop. The result shows that the biomass is increased 580 t after land consolidation, meaning the impression of land consolidation is ...

Effects of processes at the population and community level on carbon dynamics of an ecosystem model [PDF]
, 2008 Ecological processes at the population and community level are often ignored in biogeochemical models, however, the effects of excluding these processes at the ecosystem level is uncertain. In this study we analyzed the set of behaviors that emerge after

Testing Ecological Theory with Lianas [PDF]
, 2018 Lianas constitute a diverse polyphyletic plant group that is advancing our understanding of ecological theory. Specifically, lianas are providing new insights into the mechanisms that control plant distribution and diversity maintenance.
