Te Paki Ecological District in Northland is regarded as a New Zealand biodiversity hotspot, but habitat loss and forest fragmentation have adversely affected many of its endemic species. We investigated the distribution and habitat associations of Mecodema tenaki (Coleoptera: Carabidae), a Te Paki endemic ground beetle whose threat status was recently changed from 'Nationally Critical' to 'Declining'. Manual searching and pitfall trapping (live-capture and lethal) were used to detect the species at 46 sites in three habitat types: native forest, pine plantation and shrubland. Between 2006 and 2010, 41 individuals were found at five locations in the east of the district, significantly increasing individual and locality records for the species. Efficacy of both forms of pitfall trapping for determining presence/absence of M. tenaki was extremely high, whereas manual searching had lower sensitivity. Beetles were only found in structurally heterogeneous native forest with a closed canopy, including edge zones. All beetles were found at sites underlain by rocks of the Parengarenga Group (mainly Kaurahoupo Conglomerate); however, neither forest community composition nor soil properties were good predictors of beetle presence. The most important factor influencing the present distribution of M. tenakiis likely to have been anthropogenic habitat disturbance. Our study shows that lethal trapping methods are not essential for studying or monitoring this threatened species. It also shows that retaining and managing even very small native forest fragments within its historical range may be important for the protection of the species, and that a site-based rather than a single-species approach is likely to be the most effective management strategy. The possibility of relocating beetles to suitable, presently unoccupied locations should not be discounted. Our results indicate that a threat ranking of 'Nationally Vulnerable' rather than 'Declining' may be more appropriate for the species. © New Zealand Ecological Society. Source

The rising number of international students studying outside their own country poses challenges for nursing education. Numbers are predicted to grow and economic factors are placing increasing pressure on tertiary institutions to accept these students. In adapting to a foreign learning environment international students must not only adapt to the academic culture but also to the socio-cultural context. The most significant acculturation issues for students are English as a second language, differences in education pedagogy and social integration and connectedness. Students studying in New Zealand need to work with Maori, the indigenous people, and assimilate and practice the unique aspects of cultural safety, which has evolved in nursing as part of the response to the principles underpinning the Treaty of Waitangi. The Hand Model offers the potential to support international students in a culturally safe manner across all aspects of acculturation including those aspects of cultural safety unique to New Zealand. The model was originally developed by Lou Jurlina, a nursing teacher, to assist her to teach cultural safety and support her students in practising cultural safety in nursing. The thumb, represents 'awareness', with the other four digits signifying 'connection" 'communication', 'negotiation' and 'advocacy' respectively. Each digit is connected to the palm where the ultimate evaluation of the Hand Model in promoting cultural safety culminates in the clasping and shaking of hands: the moment of shared meaning. It promotes a sense of self worth and identity in students and a safe environment in which they can learn. Source

The New Zealand cave weta fauna is large and diverse but poorly described. This study aimed to improve the strategies for cave weta identification and, in doing so, build an understanding of population dynamics and distribution of the taxon across three habitat types in the Te Paki Ecological District. Species identification used morphological traits and metric analysis of specimens in pitfall traps. Although nearly half the individuals were juveniles (< 10 mm long) that could not readily be distinguished from one another, four species were identified from the larger specimens. Capture rates of cave weta varied by species, habitat, month and the interactions of these variables. Nearly half of all identified cave weta individuals in our sample were Neonetus variegatus, which was abundant across all three habitats (pine forest, native forest and shrubland) throughout the year, but were caught in pitfall traps in the greatest numbers in some pine forest sites. A species of Pachyrhamma was also abundant and showed seasonal variation in capture rate, but no adults were captured by pitfall traps. Talitropsis sp. and Pallidoplectron sp. were least frequent in our sample. Taxonomic resolution improves ecological inference, but, as with other invertebrates, trapping method and design influence sampling outcome among species. © 2015 The Royal Society of New Zealand.

Spiders in the endemic New Zealand genus Pahoroides (Araneae: Synotaxidae) are all morphologically very similar. Two species, Pahoroides whangarei and Pahoroides confusa, coexist in Pukenui Forest near Whangarei, Northland, living in vegetation close to the ground. We tested the hypothesis that P. whangarei and P. confusa occupy distinct ecological niches defined more by conditions at the microhabitat level than at the macrohabitat level. Twenty random sites within Pukenui Forest, from which a range of macrohabitat and microhabitat variables were collected, were sampled by beating vegetation for Pahoroides spiders. Both species were distributed throughout the forest, and in many cases, were found at the same sites. However, neither the presence nor abundance of one Pahoroides species was associated with that of the other. Whereas macrohabitat variables such as aspect, litter cover and overall plant community composition were not associated with either species, a significant association was found between Pahoroides species and the plant hosts upon which they were collected. Pahoroides whangarei was found mostly on the foliage of crown fern (Blechnum discolor) and kiekie (Freycinetia banksii), whereas P. confusa was most often found in the fallen fronds of ni¯kau (Rhopalostylis sapida). Our findings support the hypothesis that the two Pahoroides species have similar habitat preferences at the macroscale, but not at the microscale. We conclude that host plant species is a dominant factor that enables the species to coexist. © 2015 The Royal Society of New Zealand. Source

The littoral macroinvertebrate faunas of 17 dune lakes on the Aupouri Peninsula in northern New Zealand were examined. Land cover of individual catchments was principally sand dunes and scrub, plantation forest, pasture, or a mixture of plantation forest and pasture. Sampling was concentrated in the sedge beds, submerged macrophytes and surface sediment layers of the littoral zone. Sixty-eight invertebrate taxa were recorded, 11-30 per lake. Relative abundance of major faunal groups differed considerably among lakes but a core group of common species was found in three quarters of them. Neither community composition, nor various measures of species richness were related significantly to catchment land cover classes. A feature of the lake fauna was the occurrence of three introduced species of Gastropoda and eight self-introduced insect species, including five dragonflies. One of the latter, Hemicordulia australiae, was found in all lakes and made up 3% of all invertebrates collected. © 2015 The Royal Society of New Zealand. Source
