Ecosystem structural changes controlled by altered rainfall climatology in tropical savannas [PDF]

Nature Communications, 2019
Changing rainfall patterns may drive changes in the structure of tropical savanna. Here Zhang et al. use satellite data from global tropical savannas, and find evidence to suggest that altered rainfall may be favouring woody plants over herbaceous plants

Pyrogenic carbon contribution to tropical savanna soil carbon storage [PDF]

Nature Communications
Savannas are fire-prone ecosystems that contribute substantially to global fire emissions, but these emissions may be partly offset by deposition of fire-derived, persistent pyrogenic carbon (PyC) in soils. Although estimates of PyC contributions to soil

Indigenous and Traditional Management Creates and Maintains the Diversity of Ecosystems of South American Tropical Savannas

Frontiers in Environmental Science, 2022
The tropical South American savannas have been occupied and manipulated by humans since the late Pleistocene. Ecologists consider that soils, hydrology, and seasonal precipitation influence the structure and composition of plants and the fire-proneness ...

MODIS Vegetation Continuous Fields tree cover needs calibrating in tropical savannas [PDF]

Biogeosciences, 2022
The Moderate Resolution Imaging Spectroradiometer Vegetation Continuous Fields (MODIS VCF) Earth observation product is widely used to estimate forest cover changes and to parameterize vegetation and Earth system models and as a reference for validation ...

Division of the tropical savanna fire season into early and late dry season burning using MODIS active fires

International Journal of Applied Earth Observations and Geoinformation, 2023
Tropical savannas and grasslands are the most frequently burned biome in the world, and fire has an important role in sustaining ecosystem processes. Modern management of fires in savannas has roots in traditions stretching back centuries, and nowadays ...

Necromys lasiurus: Lessons From a 38-Year Study in an Amazonian Savanna

Frontiers in Ecology and Evolution, 2021
Amazonian savannas are isolated patches of open habitats within an array of extensive tropical forest. The mammal fauna of the savannas in the Alter do Chão region (Santarém Municipality), is dominated by Necromys lasiurus, whose populations have been ...

Seasonal drivers of mixed-species flocks from tropical savannas: insights from the Pantanal wetland

Journal of Field Ornithology, 2023
Birds participate in different types of multi-species groups (e.g., mixed-species flocks) occurring from temperate to tropical forest and also savannas.

Trees at the Amazonia-Cerrado transition are approaching high temperature thresholds

Environmental Research Letters, 2021
Land regions are warming rapidly. While in a warming world at extra-tropical latitudes vegetation adapted to higher temperatures may move in from lower latitudes this is not possible in the tropics.

Interpreting and Correcting Cross-scale Mismatches in Resilience Analysis: a Procedure and Examples from Australia's Rangelands

Ecology and Society, 2005
Many rangelands around the globe are degraded because of mismatches between the goals and actions of managers operating at different spatial scales. In this paper, we focus on identifying, interpreting, and correcting cross-scale mismatches in rangeland ...

Challenges and opportunities in land surface modelling of savanna ecosystems [PDF]

Biogeosciences, 2017
The savanna complex is a highly diverse global biome that occurs within the seasonally dry tropical to sub-tropical equatorial latitudes and are structurally and functionally distinct from grasslands and forests.
