Radiocarbon, 18O, and chemical concentrations have been used to identify groundwater recharged during the last ice age near Nelson, New Zealand. Moutere Gravel underlies most of the Moutere Depression, a 30-km-wide system of valleys filled with Plio-Pleistocene gravel. The depression extends northwards into Tasman Bay, which was above sea level when the North and South Islands of New Zealand were connected during the last glaciation. The aquifers are tapped by bores up to 500 m deep. Shallow bores (50–100 m) tap “pre-industrial” Holocene water (termed the “modern” component) with 14C concentrations of 90 ± 10 percent modern carbon (pMC) and δ18O values of −6.8 ± 0.4, as expected for present-day precipitation. Deeper bores discharge water with lower 14C concentrations and more negative 18O values resulting from input of much older water from depth. The deep end-member of the mixing trend is identified as paleowater (termed the “glacial” component) with 14C concentration close to 0 pMC and more negative 18O values (-7.6). Mixing of the modern and glacial components gives rise to the variations observed in the 14C, 18O, and chemical concentrations of the waters. Identification of the deep groundwater as glacial water suggests that there may be a large body of such water onshore and offshore at deep levels. More generally, the influence of changing sea levels in the recent past (geologically speaking) on the disposition of groundwaters in coastal areas of New Zealand may have been far greater than we have previously realized.

The aim of this chapter is to situate the unique discoveries of cave art at the Creswell Crags caves in the context of what is known of the cave archaeology and palaeontology of the caves of the southern Magnesian Limestone outcrop. The long history of archaeological research at Creswell Crags and the spectacular discoveries that continue to be made in the Creswell caves have tended to overshadow the widespread though less prominent distribution of cave archaeological sites along the limestone outcrop to the north and south of Creswell, a region known as the Creswell Crags Limestone Heritage Area (Mills 2001). Recent audits of the archaeology of the region have drawn attention to the large number of cave sites within the Limestone Heritage Area as well as the considerable potential that these sites have for further research into the history of Ice Age people and their environments (Mills 2001; Davies et al. 2004).While the focus of this chapter is on the Pleistocene deposits and Palaeolithic artefacts that have been preserved in the region’s caves, fissures, and rock shelters, these sites were used throughout prehistory by humans and animals and they contain much important cultural and environmental evidence for these later time periods after the end of the last Ice Age. Creswell Crags is located in the southern part of the Magnesian Limestone, a geological term for deposits of Upper Permian age that includes a series of formations of well-bedded oolitic to dolomitic limestones. The Magnesian Limestone forms a narrow north–south oriented outcrop that runs from near Nottingham in the south to the North Sea coast near Tynemouth in the north (Fig. 6.1). About 30 km to the west of the southern part of the Magnesian Limestone is the older Carboniferous Limestone outcrop of the White Peak, which, like the Magnesian Limestone, contains many archaeological caves. The southern part of the Magnesian Limestone outcrop, between Doncaster and Mansfield, is cut through by a series of vales and gorges which expose caves, fissures, and rockshelters along the cliff lines.

Abstract The Laurentide and Fennoscandian ice sheets had three major glaciation maxima during the Last Ice Age. All data from the southern margins of the ice sheets indicate that these maxima, as well as minor fluctuations, were synchronous. The same synchroneity is supposed to apply also for correlations between fluctuations on the north and south margins, which reveal a continuously southward displacement of the distribution of glaciation during the Last Ice Age. This southward displacement explains the saw-tooth pattern of 18O records from deep-sea cores in which the first glaciation maximum is under-represented due to its distribution more towards the north. The synchroneity is consistent with a global climatic control of the stadial/interstadial changes and with the recorded global eustatic changes. The southward displacement of glaciation seems to be a general rule also applicable to earlier Pleistocene glaciations.

Some 2,000 Ptiliidae collected in the North and South Islands of New Zealand in 1983/1984 by Peter Hammond of the Natural History Museum, London, are determined to 34 species, four of which are new to the country. As there are very few previous records, most from the Auckland district of North Island, the Hammond collection provides much new distributional data. The three new species: Nellosana insperatus sp. n., Notoptenidium flavum sp. n., and Notoptenidium johnsoni sp. n., are described and figured; the genus Ptiliodes is moved from Acrotrichinae to Ptiliinae, and Ptenidium formicetorum Kraatz recorded as a new introduction. Information is provided to aid separation of the new species from those previously recorded.

AbstractOn the west coast of North America and in Australia, there have been parallel cases of sequential invasion and replacement of the shoreline plant American sea-rocket by European sea-rocket. A similar pattern has also occurred in New Zealand. For 30 to 40 yr, from its first recording in 1921, American sea-rocket spread throughout the eastern coastlines of the North and South Islands of New Zealand. European sea-rocket has so far been collected only on the North Island. From its first collection in 1937, European sea-rocket spread to the northern extremity of the island by 1973, and by 2010, it had reached the southernmost limit. In the region where both species have occurred in the past, American sea-rocket is now rarely found. This appears to be another example of congeneric species displacement.

This report describes the outcomes of extensive research (questionnaires, focus groups, drawings) on the media use of students aged between eight and 13 years (n=860) in the North and South Islands of New Zealand. The research replicates earlier child-centred research by the authors, but with a greater emphasis on newer media technology, such as cell phones. The various facets of the research, framed within theoretical explorations, produced detailed and often candid insights into the role played by contemporary media in the lives of New Zealand children with respect to the overt and covert use of technology, shifts in relationships between children and adults. It also generated some interesting cautionary tales.

The New Zealand species of the water scavenger beetle genus Berosus Leach, 1817 are reviewed based on freshly collected material and museum specimens. Four species are recognized: Berosus pallidipennis (Sharp, 1884) widespread in the North and South Islands, B. muellerorum sp. nov. from the eastern part of the North Island, and B. halasi sp. nov. and B. maru sp. nov., both endemic to central part of South Island. The synonymy of B. mergus Broun, 1886 with B. pallidipennis is confirmed and lectotypes for both taxa are designated. The larval morphology of B. pallidipennis and B. muellerorum is briefly discussed. Distributional data of all species are reported and illustrated, indicating a noticeable lack of Berosus species in the northern part of North Island and in Stewart Island and the presence of two rare species in the South Island, east of Southern Alps. An identification key to New Zealand species of the genus is provided

To estimate the prevalence of herbicide-resistant weeds, 87 wheat and barley farms were randomly surveyed in the Canterbury region of New Zealand. Over 600 weed seed samples from up to 10 mother plants per taxon depending on abundance, were collected immediately prior to harvest (two fields per farm). Some samples provided by agronomists were tested on an ad-hoc basis. Over 40,000 seedlings were grown to the 2–4 leaf stage in glasshouse conditions and sprayed with high priority herbicides for grasses from the three modes-of-action acetyl-CoA carboxylase (ACCase)-inhibitors haloxyfop, fenoxaprop, clodinafop, pinoxaden, clethodim, acetolactate synthase (ALS)-inhibitors iodosulfuron, pyroxsulam, nicosulfuron, and the 5-enolpyruvyl shikimate 3-phosphate synthase (EPSPS)-inhibitor glyphosate. The highest manufacturer recommended label rates were applied for the products registered for use in New Zealand, often higher than the discriminatory rates used in studies elsewhere. Published studies of resistance were rare in New Zealand but we found weeds survived herbicide applications on 42 of the 87 (48%) randomly surveyed farms, while susceptible reference populations died. Resistance was found for ALS-inhibitors on 35 farms (40%) and to ACCase-inhibitors on 20 (23%) farms. The number of farms with resistant weeds (denominator is 87 farms) are reported for ACCase-inhibitors, ALS-inhibitors, and glyphosate respectively as: Avena fatua (9%, 1%, 0% of farms), Bromus catharticus (0%, 2%, 0%), Lolium spp. (17%, 28%, 0%), Phalaris minor (1%, 6%, 0%), and Vulpia bromoides (0%, not tested, 0%). Not all farms had the weeds present, five had no obvious weeds prior to harvest. This survey revealed New Zealand’s first documented cases of resistance in P. minor (fenoxaprop, clodinafop, iodosulfuron) and B. catharticus (pyroxsulam). Twelve of the 87 randomly sampled farms (14%) had ALS-inhibitor chlorsulfuron-resistant sow thistles, mostly Sonchus asper but also S. oleraceus. Resistance was confirmed in industry-supplied samples of the grasses Digitaria sanguinalis (nicosulfuron, two maize farms), P. minor (iodosulfuron, one farm), and Lolium spp. (cases included glyphosate, haloxyfop, pinoxaden, iodosulfuron, and pyroxsulam, 9 farms). Industry also supplied Stellaria media samples that were resistant to chlorsulfuron and flumetsulam (ALS-inhibitors) sourced from clover and ryegrass fields from the North and South Island.

<p>This study examines the final emergence of the southeastern Wairarapa within a sequence stratigraphic framework. New exposures of the Pleistocene marginalmarine Hautotara Formation, and non-marine Te Muna Formation allow facies to be detailed and sequence architecture to be analysed. Cyclicity observed within the facies successions of the Hautotara and Te Muna formations are placed in a series of four motifs. These motifs record 40 kyr glacioeustatic cyclicity superimposed upon the basinward to landward progression of the environments, showing the region shallowing through time. The positions of the top of the Pukenui Limestone and the base of the Hautotara Formation are revised, and are now at the top of the “Pukenui C” - a widespread marker bed, which also removes a historical nomenclatural gap. The recognition of the significance of the coccolith Gephyrocapsa sinuosa within the underlying Pukenui Limestone allows this contact to be dated at 1.73 Ma. The ~1.6 Ma age limit provided by a number of tephra within the lower sediments of the Te Muna Formation allow the ages of the examined formations to be constrained further. The eight 40 ka cycles identified within the Hautotara Formation suggests deposition between 1.73 and 1.42 Ma. The Hautotara - Te Muna Formation is revealed to be diachronous, with the base of the Te Muna Formation type section shown to be much younger, 1.12 Ma, than the 1.58 Ma age of the lower contact observed elsewhere in the region. A series of palaeogeographic reconstructions at 1.73, 1.58 and 1.57 Ma demonstrate how closely related sedimentation patterns are to structural growth, with marginal-marine Hautotara Formation sedimentation persisting in the centre of the study area well after the initiation of Te Muna Formation terrestrial deposition to the north and south of this site.</p>
