Carbon Markets and Natural Climate Solutions in Brazil: Institutional Coherence Across Biodiversity, Land‐Use and Territorial Governance

Environmental Policy and Governance, EarlyView.
ABSTRACT This study examines how natural climate solutions (NCS) are institutionalised through carbon market governance in tropical contexts, focusing on Brazil's emerging Emissions Trading System (SBCE). It contributes to debates on the effectiveness, equity and governance of nature‐based climate action by analysing how carbon market instruments ...

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.

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.
