Aspects of the production and vegetative performance of Calluna vulgaris (heather) were examined in four areas of New Zealand between 1981 and 1983; Tongariro National Park in the North Island, together with Mount Cook National Park, the Wilderness Scientific Reserve, and Ben Callum peat bog in the South Island. The height and height/width quotient of(More)
Recovery of a sexual and an apomictic hybrid from crosses between the facultative apomicts Hieracium caespitosum and H. praealtum Abstract: Hybridisation is a rare event in facultatively apomictic species. We report the recovery of two hybrids from reciprocal crosses between the facultatively apomictic species Hieracium praealtum and H. caespitosum. Both(More)
The grass genus Chionochloa in New Zealand exhibits a high degree of mast seeding synchronised across species and habitats. Masting appears to be maintained by a predator satiation mechanism involving three pre-dispersal seed-and flower-feeding insects. It is not clear how important each of the three insects is in favouring the masting strategy. An(More)
Understanding nest site choice by chimpanzees has implications for ecology, anthropology, and in the collection of census data, yet it remains controversial. Here we provide the first information on environmental factors affecting nest site choice in a montane population of the rare and relatively understudied Nigerian/Cameroon chimpanzee (Pan troglodytes(More)
Animal pollinators and the plants they pollinate depend on networks of mutualistic partnerships and more broadly on the stability of such networks. Based mainly on insect-plant visitation networks, theory predicts that species that are most prone to extinction contribute the most to nestedness, however empirical tests are rare. We used a sunbird-tree(More)
Metagenomic approaches are rapidly expanding our knowledge of the diversity of viruses. In the fecal matter of Nigerian chimpanzees we recovered three gokushovirus genomes, one circular replication-associated protein encoding single-stranded DNA virus (CRESS), and a CRESS DNA molecule.
Regional variations in tool use among chimpanzee subspecies and between populations within the same subspecies can often be explained by ecological constraints, although cultural variation also occurs. In this study we provide data on tool use by a small, recently isolated population of the endangered Nigeria–Cameroon chimpanzee Pan troglodytes ellioti,(More)
Very little is known regarding health-care professionals' understanding and experiences of respect towards patients. The study aimed to explore student nurses' understanding and experiences of respect in their encounters with patients. Semi-structured interviews were conducted with eight final-year student nurses with practice placements across different(More)
DOC Science Internal Series is a published record of scientific research carried out, or advice given, by Department of Conservation staff, or external contractors funded by DOC. It comprises progress reports and short communications that are generally peer-reviewed within DOC, but not always externally refereed. Fully refereed contract reports funded from(More)
Two male Angora goats presented with ataxia and weakness of the hind limbs. Both tired easily when exercised and often stumbled and fell. In both cases, post-mortem examination revealed focal areas of gliosis and diffuse Wallerian degeneration in the spinal cord at the level of the atlanto-axial joint. There were also two areas of myelomalacia in one of the(More)
