Foot-and-mouth: when the call came

Plants in cyberspace

Black water fish

Life on undersea volcanoes

Hypothetical foot-and-mouth viral plumes over Waiheke Island for actual weather conditions on 12 & 13 May 2005, assuming four properties with pigs were possible sources of infection.
The presence of torrentfish after some 20 years of rafting is encouraging. In Waitomo Caves, native fish live quietly alongside wetsuit clad tourists. Scientists from NIWA and DOC, and experienced caving guides from the Black Water Rafting Company, recently conducted a preliminary survey of three cave systems there.
New freshwater plant datasets are now available on-line Alligator weed (Alternanthera philoxeroides) is a major weed of water margins and can invade damp pastures. It is just one of the pest plants for which FBIS can provide details of its distribution and current management. They are part of the latest version of NIWA’s Freshwater Biodata Information System (FBIS).
Mussel beds, with Paralomis crabs crawling over them, and clumps of tubeworms on Monowai volcano. New Zealand and American scientists recently used a submersible to explore some of the active volcanoes along the Kermadec Arc, northeast of the Bay of Plenty. The volcanoes’ hydrothermal vents can release high concentrations of toxic gas and spew out liquid up to 400°C.
