Declining plant species richness in the tussock grasslands of Canterbury and Otago, South Island, New Zealand
We studied vegetation change on 142 permanently marked transects spread throughout tussock grasslands of Otago and Canterbury, in areas subject to both pastoral and conservation management. The transects were established between 1982 and 1986 and re-measured between 1993 and 1999, providing a record of vegetation change at each site over an interval varying from 10 to 15 years. Each transect co...
متن کاملFossil isopod and decapod crustaceans from the Kowai Formation (Pliocene) near Makikihi, South Canterbury, New Zealand
Small concretions and specimens embedded in the matrix have yielded a new Pliocene crustacean fauna from the Kowai Formation near Makikihi, South Canterbury, New Zealand. The fauna is relatively robust, with five identifiable taxa. Three new species are named herein, including the isopod Cirolana makikihi and the decapods Upogebia kowai and Austrohelice manneringi. one new genus and species of ...
متن کاملGroundwater Recharge Interface and Nitrate Discharge: Central Canterbury, New Zealand
Regional surveys of groundwater quality in Central Canterbury, from 1977 to the present, show widespread occurrence of nitrate contamination primarily from agricultural land use. Two reported analyses of these surveys, in 1984 and 2002, describe a general decrease of nitrate concentration with depth from the groundwater table to uncontaminated water at about 50-80 m. This high quality water is ...
متن کاملOldest Known Eucalyptus Macrofossils Are from South America
The evolutionary history of Eucalyptus and the eucalypts, the larger clade of seven genera including Eucalyptus that today have a natural distribution almost exclusively in Australasia, is poorly documented from the fossil record. Little physical evidence exists bearing on the ancient geographical distributions or morphologies of plants within the clade. Herein, we introduce fossil material of ...
متن کاملTrend in Bare Ground from Tussock Grassland Surveys, Canterbury, New Zealand
Trend in the proportion of bare ground in some Canterbury tussock grasslands is analysed using records of vegetative cover from Fox Peak, South Opuha River (1963-1985); Porter River (1976-1984); Waimakariri Basin (1962-1978); and central Waimakariri River (1947-1981). The overall proportion of bare ground changed little in all four surveys. The lowest altitude site at Fox Peak and a low altitud...
