Connectivity and complexity of floodplain habitats govern zooplankton dynamics in a large temperate river system
Górski, Konrad; Collier, Kevin J.; Duggan, Ian C.; Taylor, Claire Maree; Hamilton, David P. (Wiley, 2013)1. Large river–floodplain systems are characterised by seasonal flow variability. High flows lead to hydrological connection between the main channel and inundated off-channel lakes, wetlands and floodplains, which provide ... -
Consequences of human-mediated marine intrusions on the zooplankton community of a temperate coastal lagoon
Duggan, Ian C.; White, Michelle A. (Routledge, 2010)Barrier bars separating lagoons from oceans are frequently breached as a management tool to prevent flooding of terrestrial ecosystems. The effects of such human-mediated openings on zooplankton have been investigated only ... -
Detection and distribution of Craspedacusta sowerbii: Observations of medusae are not enough
Duggan, Ian C.; Eastwood, Kevin R. (Regional Euro-Asian Biological Invasions Centre (REABIC), 2012)The freshwater cnidarian Craspedacusta sowerbii, native to the Yangtze valley, has invaded lakes and ponds throughout the world. Most distribution records have to date been based on observations of the medusa (jellyfish) ... -
Effects of introduced fish on zooplankton – fact sheet
Duggan, Ian C. (Lake Ecosystem Restoration New Zealand (LERNZ), University of Waikato, 2015)Zooplankton are small animals that feed on algae and bacteria in lakes, and are in turn food for small fish. Three major zooplankton groups exist in lakes; the cladocerans and copepods, which are both small crustaceans, ... -
The freshwater aquarium trade as a vector for incidental invertebrate fauna
Duggan, Ian C. (Springer, 2010)The aquarium trade has a long history of transporting and introducing fish, plants and snails into regions where they are not native. However, other than snails, research on species carried “incidentally” rather than ...
