Recent occurrence of Cylindrospermopsis raciborskii in Waikato lakes of New Zealand
Cylindrospermopsis raciborskii is a toxin-producing species of cyanobacteria that in autumn 2003 was recorded for the first time in three shallow (max. depth £5 m) Waikato lakes and a hydro-electric dam on the Waikato River, New Zealand. It formed water blooms at densities >100 000 cells/ml in Lakes Waahi and Whangape. Net rates of population growth >0.2 day–1 were recorded for C. raciborskii i...

متن کاملModelling Relationships between Environment and Canopy Composition in Secondary Vegetation in Central North Island, New Zealand
Relationships between composition of secondary vegetation and environment were studied in central North Island, New Zealand. A classification procedure was used to identify broad compositional groups which included forest, broadleaved scrub, shrub-fernland, sclerophyllous scrub and shrubland, and tussock-shrubland. Generalised additive models (GAMs) were used to examine relationships between sp...
متن کاملVegetation Mortality in the Kaimai Ranges, North Island, New Zealand!
Areas ofvegetation mortality have been recognized in the upland forests of the Kaimai Ranges, North Island, New Zealand. The mortality is not confined to any particular vegetation type, but occurs above a critical altitude that differs at different points along the ranges. The mortality is episodic and has occurred at intervals over a period of several hundred years, with severe droughts implic...
متن کاملDietary composition of Gambusia affinis (Family Poeciliidae) populations in the northern Waikato region of New Zealand
Invertebrates were collected and identified from the stomach contents of eight mosquitofish (Gambusia affinis) populations in the northern Waikato region of New Zealand at 3-month intervals from December 1994 to September 1995. To investigate temporal and spatial patterns in dietary composition a novel analysis programme was created that used Gower's similarity coefficient. The analysis found d...
