Regime shifts occur disproportionately faster in larger ecosystems

Regime shifts can abruptly affect hydrological, climatic and terrestrial systems, leading to degraded ecosystems and impoverished societies. While the frequency of regime shifts is predicted to increase, the fundamental relationships between the spatial-temporal scales of shifts and their underlying mechanisms are poorly understood. Here we analyse empirical data from terrestrial (n = 4), marine (n = 25) and freshwater (n = 13) environments and show positive sub-linear empirical relationships between the size and shift duration of systems.

High Mountain Conservation in a Changing World

Protected natural areas deserve the combination of nature uniqueness and conservation willing. The foundation stone for National Parks is the awareness of that unique character—actual or presumed, most times based on non-tangible properties or singularities —grown in some social sectors, followed by the aim of preserving particular biota, singular ecosystems or entire landscapes. This was the case for the Aigüestortes i Estany de Sant Maurici National Park. Like other protected areas in alpine mountains, its apparent wilderness was a key factor in declaring it National Park, in 1955.

Marine and Coastal Biodiversity (MACBIO) - Tonga

MACBIO is a project that supports sustainable economies and livelihoods of Pacific Island Countries by strengthening institutional and individual capacity, to manage and conserve biodiversity in marine and coastal ecosystems. The project was commissioned by BMUB to GIZ as part of IKI, jointly implemented by SPREP, IUCN and GIZ from 2013 to 2018.
This dataset holds all MACBIO-related resources pertaining to Tonga as one of the participating countries.
