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 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

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

Tree-Grass interactions dynamics and Pulse Fires: mathematical and numerical studies

, 2015
Savannas are dynamical systems where grasses and trees can either dominate or coexist. Fires are known to be central in the functioning of the savanna biome though their characteristics are expected to vary along the rainfall gradients as observed in Sub-

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

Sensitivity of the grassland-forest ecotone in East African open woodland savannah to historical rainfall variation [PDF]

, 2014
. Fossil pollen records provide key insight into the sensitivity of terrestrial ecosystems to climate change at longer time scales. However, tracing vegetation response to relatively modest historical climate fluctuations is often complicated by the ...

Evaluating the African arid corridor hypothesis: A meta‐analysis including the phylogenetic and biogeographical history of Sesamothamnus

American Journal of Botany, EarlyView.
Abstract Premise We examined the African arid corridor (AAC) disjunction pattern of vascular plants between northeastern and southwestern Africa in the context of geological and climatic events since the late Miocene. We developed a phylogenetic and biogeographical framework for the arid‐adapted genus Sesamothamnus (Pedaliaceae), a classic example of ...

Contribution of NOAA- AVHRR data to African savan nahs Characterization [PDF]

, 2005
The Advanced Very High Resolution Radiometer (AVHRR) is currently used for vegetation monitoring. Information on the state and evolution of the vegetation cover on continental areas is routinely obtained from Global Vegetation Index data (GVI).
