An Overview of Rhodoliths: Ecological Importance and Conservation Emergency.

Red calcareous algae create bio-aggregations ecosystems constituted by carbonate calcium, with two main morphotypes: geniculate and non-geniculate structures (rhodoliths may form bio-encrustations on hard substrata or unattached nodules). This study presents a bibliographic review of the order Corallinales (specifically, rhodoliths), highlighting on morphology, ecology, diversity, related organisms, major anthropogenic influences on climate change and current conservation initiatives. These habitats are often widespread geographically and bathymetrically, occurring in the photic zone from the intertidal area to depths of 270 m.

Exploring social-ecological systems in the transition from war to peace: A scenario-based approach to forecasting the post-conflict landscape in a Colombian region.

This paper describes the relationship between the landscape and the socio-economic and political characteristics of a highly biodiverse Andean region of Colombia, which is now recovering from the socio-ecological impact of protracted armed conflict. We quantify the current spatial relationship between nature and society, and we include legacy effects from the most recent period of armed conflict and its consequences of forced displacement and land use disruption. The procedure followed provides a quantitative model where a minimum number of socio-economic and political variables explain the variation in land cover.
