The Global South's OCBIL Theory Helps Elucidate Evolution, Ecology, and Conservation in Biological and Cultural Diversity

New Zealand Journal of Zoology, Volume 53, Issue 3, September 2026.
Ecological theory has been shaped disproportionately by studies conducted in young, disturbance‐prone, relatively fertile landscapes (YODFELs), mostly in the Global North. Yet, many megadiverse regions in the Global South are dominated by old, climatically buffered, infertile landscapes (OCBILs), resulting in fundamentally different patterns that ...

Comprehensive Analysis for the Evaluation of Torrential Floods and Slope Stability of River Channels: La China River Area (Colombia)

Journal of Flood Risk Management, Volume 19, Issue 3, September 2026.
Colombia and other tropical regions face a very high threat from torrential floods, which have resulted in over 25,000 deaths in a single event. Unfortunately, there is no comprehensive assessment methodology to zone and determine the magnitude of these disasters; therefore, this research aims to help fill this gap.

Extent, characteristics and policy applications of Key Biodiversity Areas

Biological Reviews, Volume 101, Issue 4, Page 1735-1759, August 2026.
ABSTRACT A global standard for the identification of Key Biodiversity Areas (KBAs) was published 10 years ago to provide a unified set of criteria for identifying ‘sites of significance for the global persistence of biodiversity’. We review the initiative's origins, the KBA identification process, characteristics of the current network, threats, policy

New canopy legume species highlight liana gap sampling across Amazonian and Atlantic rain forests

TAXON, Volume 75, Issue 4, August 2026.
Abstract Lianas are a key component of the Neotropical flora, accounting for 10% of angiosperm richness and playing important ecological roles. However, the canopy preference of some species often leads to their underrepresentation in herbarium collections, thereby exacerbating Linnaean, Darwinian, and Wallacean shortfalls. The papilionoid legume genus
