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)

open access: yesJournal 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.

Reflecting on research produced after more than 60 years of exclosures in the Kruger National Park

open access: yesKoedoe: African Protected Area Conservation and Science, 2022
Herbivores are a main driver of ecosystem patterns and processes in semi-arid savannas, with their effects clearly observed when they are excluded from landscapes.

Bulbophyllum weddellii (Orchidaceae) demonstrates foliar water uptake plasticity along Brazilian campos rupestres

open access: yesNordic Journal of Botany, EarlyView.
Phenotypic plasticity can facilitate species survival in a variety of conditions that are not possible with a fixed phenotype. Foliar water uptake (FWU), defined as the absorption of water through leaf surfaces, is an important mechanism contributing to plant water balance and drought tolerance in many species.

Comparative Analysis of the Global Forest/Non-Forest Maps Derived from SAR and Optical Sensors. Case Studies from Brazilian Amazon and Cerrado Biomes

open access: yesRemote Sensing, 2021
Global-scale forest/non-forest (FNF) maps are of crucial importance for applications like biomass estimation and deforestation monitoring. Global FNF maps based on optical remote sensing data have been produced by the wall-to-wall satellite image ...

Capsicum chinense as an African traditional vegetable: Culture, resilience, and opportunity

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Capsicum chinense is central to everyday diets, cultural identity, and smallholder livelihoods across Sub‐Saharan Africa, yet remains overlooked in agricultural research and policy. This paper reframes C. chinense as a traditional, climate‐resilient vegetable shaped by centuries of farmer stewardship and cultural selection.

Brazil seed transfer zones: Supporting seed sourcing for climate‐resilient ecosystem restoration

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Brazil has tens of millions of hectares of degraded land that must be restored to meet national and global biodiversity and climate goals. Sowing genetically diverse native seeds is key to restoring degraded lands to climate‐resilient landscapes, but we still lack guidance on how to effectively match seed sources to restoration sites across broad ...

Temporal changes in species composition, diversity, and woody vegetation structure of savannas in the Cerrado-Amazon transition zone

open access: yesActa Botânica Brasílica, 2018
Vegetation in the transition between tropical forest and savanna is hyperdynamic and there is evidence that in the absence of fire, forest advances over savanna.

Beyond forests: Harnessing conservation gardening for open biomes in Brazil

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Urban gardening offers an innovative conservation strategy by integrating native ornamental species into urban landscapes. We evaluated the ornamental potential of the Brazilian flora by comparing the representation of species from forests versus open biomes (focusing on campo rupestre grasslands) and introduced and validated the Index of Ornamental ...

Dispersal increases the resilience of tropical savanna and forest distributions [PDF]

open access: yesThe American Naturalist, 2018
Abstract Global change may induce changes in savanna and forest distributions, but the dynamics of these changes remain unclear. Classical biome theory suggests that climate is predictive of biome distributions, such that shifts will be continuous and reversible.

Peri‐urban agroforestry for climate mitigation in West Africa: Structural diversity and functional traits as key drivers of carbon storage

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Peri‐urban areas in West Africa are expanding rapidly, often with limited planning and growing exposure to climate risks. Our study shows that agroforestry systems in these landscapes, especially diverse home gardens, can store substantial amounts of carbon when they include structurally complex stands and species with traits that favor biomass ...
