Habitat and population structure of rare and endemic Andean Espeletia pycnophylla subsp. llanganatensis (Asteraceae) in an Ecuadorian biodiversity hotspot

High-elevation neotropical environments of the Andes include the Páramo, a biodiversity hotspot with fast speciation rates. The genus Espeletia is distinctive of this ecosystem in the northern Andes. Its southern...

Living on the edge: high-latitude Porites carbonate production under temperate eutrophic conditions

Non-framework building high-latitude coral communities have recently received increased attention as a result of their potential to act as refugia during global change, as proxies for such change and for testi...

Climate change and coral reefs: different effects in two high-latitude areas (Arabian Gulf, South Africa)

The findings in this paper show that Arabian Gulf (Abu Dhabi, Dubai, Sharjah) corals have already been measurably affected by climate change and further negative impacts are expected. Corals in South Africa ha...

Possible refugia for reefs in times of environmental stress

This paper investigates the refuge potential of (1) upwelling areas, (2) coral areas at medium depth, and (3) offshore bank and island reefs in a scenario of increased global warming, and thus increased sea su...
