Imagine del die

Short-nosed unicornfish (Naso brevirostris), Red Sea, Egypt. This species has a maximum published total length of 60 centimetres (24 in). It occurs in the Indian and western Pacific Oceans. Adults feed mainly on gelatinous zooplankton, while juveniles mainly feed on benthic algae. The switch from grazing to preying on gelatinous zooplankton coincides with the development of the bony protuberance.

Objecto multimedial del die

Due to climate change, coffee is in crisis – the land suitable for coffee production could shrink by as much as half by 2050, due to higher temperatures and extreme weather. This documentary video by Context News investigates global warming impacts on coffee production and a coffee species, cultivated and traded around the world more than century ago, that may become more important due to these changes.
