Forests, savannas, and grasslands: bridging the knowledge gap between ecology and Dynamic Global Vegetation Models [PDF]

Biogeosciences, 2015
The forest, savanna, and grassland biomes, and the transitions between them, are expected to undergo major changes in the future due to global climate change.

Forest vs Savanna dynamics in the contact zones of French Guiana

Revue Française de Photogrammétrie et de Télédétection, 2014
Savannas and tropical forests delineated by sharp boundaries are two alternative stable ecosystems. What is the natural evolution of forests over savannas in coastal savanna in French Guiana?

Urban Growth and Heat in Tropical Climates

Frontiers in Ecology and Evolution, 2021
This research describes the change in temperatures across approximately 270 tropical cities from 1960 to 2020 with a focus on urban warming. It associates urban growth indicators with temperature variations in tropical climate zones (tropical rainforest,

Impacts of climate extremes on vegetation health in the tropical savannas of Africa

Global Ecology and Conservation
The tropical savanna of Africa, which covers 65 % of the continent, supports livelihood, livestock, crops and wildlife, playing an important role in socio-economic development in Africa. However, these ecosystems experience high temperatures and distinct

Impacts of an extreme cyclone event on landscape-scale savanna fire, productivity and greenhouse gas emissions

Environmental Research Letters, 2013
North Australian tropical savanna accounts for 12% of the world’s total savanna land cover. Accordingly, understanding processes that govern carbon, water and energy exchange within this biome is critical to global carbon and water budgeting. Climate and

Herbarium‐based measurements are reliable predictors of fresh plant traits in Neotropical Myrtaceae

Applications in Plant Sciences, EarlyView.
Abstract Premise Herbarium specimens are increasingly used to extract morphological traits for ecological and evolutionary studies, yet the effects of tissue desiccation on trait measurements remain poorly understood. Here, we tested two hypotheses: (H1) whether higher tissue water content leads to greater measurement changes after herborization and ...

Ecosystem structural changes controlled by altered rainfall climatology in tropical savannas

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

Are there morpho‐acoustic patterns of adaptation in nonhuman primate ears? Testing the role of ecology and habitat in shaping ear morphology and function

The Anatomical Record, EarlyView.
Abstract Analysis of the variation in the bony structures of the inner and middle ear provides critical insights into functional morphology, as well as adaptive morphology across primates. In this study, we investigated whether ear morphology patterns are related to the ecological characteristics of species and their habitats to test two acoustic ...

Afforestation of tropical savannas has mixed consequences for bird communities

Conservation Science and Practice
Land‐use change is a key driver of tropical savanna biodiversity and one such widespread change is the conversion of ancient (i.e., old‐growth) savannas to tree plantations.
