Resolving the biome debate: ecological and palaeo‐data concur that the extensive tree‐limited grassy biomes of central and north‐western Madagascar are largely anthropogenic

Biological Reviews, EarlyView.
ABSTRACT For millennia, human activities have transformed ecosystems globally. Determining which landscapes are predominantly anthropogenic is crucial to conservation and habitat restoration. Madagascar, a critically‐threatened biodiversity hotspot, is a prominent example.

Long-term field experiments carried out in savannas and hillsides agroecosystems by Soil Physics (PE-2: Soils project of CIAT)

, 2016
The soil physics (PE-2: Soils project of CIAT) had several field experiments in both tropical savannas and hillsides agroecosystems. To organize the data, three big blocks were established: one block for hillsides agroecosystem and two blocks ...

Dental enamel hypoplasia and intra‐tooth isotope records as indicators of physiological stress and environmental variability in Early Pleistocene hippopotamids from Melka Kunture (Upper Awash, Ethiopia)

Journal of Quaternary Science, EarlyView.
ABSTRACT Enamel hypoplasia results from temporary disruptions of enamel deposition during tooth development. It is widely used as an indicator of physiological stress in archeological and paleontological contexts; yet, its relationship with environmental conditions during tooth formation remains poorly constrained.

Between desert and forest: the Holocene savannas of NE-Nigeria [PDF]

, 2006
Numerous ecologists postulate that West African savannas are mostly the result of degradation of formerly closed forests. This hypothesis can only be tested by palaeoecological investigations.

A new old species of Tetracera (Dilleniaceae) from Espinhaço Range, Brazil

Nordic Journal of Botany, EarlyView.
Tetracera is the only genus within Dilleniaceae with a pantropical distribution. During efforts for a taxonomic revision of the neotropical species, we identified incongruences between application of names and their taxonomic identities, based on protologue and type specimen analysis. Here we describe a new species for the genus bearing a single carpel

Woody Plant Encroachment in a Seasonal Tropical Savanna: Lessons about Classifiers and Accuracy from UAV Images

Remote Sensing, 2023
Woody plant encroachment in grassy ecosystems is a widely reported phenomenon associated with negative impacts on ecosystem functions. Most studies of this phenomenon have been carried out in arid and semi-arid grasslands.

The importance of biodiversity components differs among wood‐based material Nature's contributions to people (NCP) in a tropical montane ecosystem

Oikos, EarlyView.
Biodiversity can influence forest productivity, but this does not necessarily translate into higher provision of wood‐based Nature's contributions to people (NCP), as only a subset of the wood produced is used for each NCP. Biodiversity–NCP relationships therefore require further assessment.

Second world record of Glomus trufemii (Glomeromycota: Fungi), an arbuscular mycorrhizal fungus from a Mexican savanna

Revista Mexicana de Biodiversidad, 2018
In Mexico, studies of diversity of arbuscular mycorrhizal fungi (AMF) are still scarce. Here we report the second record in the world, and the first record in Mexico of Glomus trufemii (Glomeraceae) from a tropical humid savanna. These results provide an
