Copepods are small crustaceans found throughout the world’s oceans. They are so common that, as a group, they may form the largest weight of animals in the world. NIWA scientists have been mapping the distribution of one species of these tiny animals.
NIWA scientists continue their research into didymo, hoping to find out more about the conditions most suited to its establishment.
NIWA is helping the Department of Conservation to ensure cruise ships don’t inadvertently carry unwanted foreign organisms on their hulls to New Zealand’s subantarctic islands.
Experiments on Antarctic shellfish at NIWA are revealing the potential effects of ocean acidification on fragile marine ecosystems.
Genetic diversity is an important component of biodiversity. Recent NIWA research shows how contaminated stormwater can reduce the genetic diversity of one model freshwater species.
Beds of New Zealand seagrass (Zostera muelleri) provide important habitat for coastal species such as small fish, seahorses, and shellfish. Much of New Zealand’s seagrass habitat has been lost or degraded, mainly as a result of sedimentation. NIWA is leading a small-scale seagrass transplantation trial in Whangarei Harbour, with promising early results.
