Despite the concern of some nineteenth- and early twentieth-century biologists, relatively few alien species have become established in undisturbed forests of Australia, Madagascar or New Zealand. All three countries have large 'naturalized' floras adapted to frequent disturbance. The short-term advantages of these alien plants - short life cycles, fast growth, abundant seed and plasticity of habit - have allowed them to cover large areas of disturbed ground and to coexist with native plants in early successional vegetation. Very few persist in mature forest. The threat to the austral forests is human disturbance, and there is need for research on the native plants which perform the specialized role of repairing canopy after disturbance.

Seed Crops

Brassica seed crops are grown throughout New Zealand and worldwide and intercrop and cropweed contamination through gene flow is a major concern For Brassica large arthropods (body length > 3 mm) particularly honey bees are the most important pollinators and are considered key vectors of pollen Small arthropods (body length < 3 mm) are also abundant in Brassica crops but their role as pollinators is rarely assessed Numerous small arthropods (particularly Diptera and Thysanoptera) were recorded within cages surrounding pak choi inflorescences that excluded large arthropods Inflorescences inside these cages set seed but seed set was significantly reduced compared with inflorescences in cages that were hand pollinated and uncaged inflorescences Although the presence of large arthropods significantly increased seed set the role of small arthropods and wind cannot be excluded in pak choi pollination Further studies are required to fully determine the role of small arthropods in long distance pollen flow

SUMMARYIn New Zealand Campylobacter infection rates have increased steadily since 1980, reaching a peak in 2003 (396/100 000 population). Compared to other nations, disease rates are unfavourably high (e.g. Australia 117/100 000 population, UK 85/100 000 population, USA 13/100 000 population). This ecological study investigated spatial variations in Campylobacter infection rates across New Zealand's Territorial Local Authorities (TLAs, n=73) for the period 1997–2005. Applying multiple linear regression, we examined whether geographical factors such as socio-demographic characteristics, climate, land use, water and the food environment were associated with local differences in the occurrence of Campylobacter infection rates. The results suggested significant variations in campylobacteriosis across TLAs (average annual rates ranging from 97 to 526/100 000 population), with higher rates in the South Island. Disease rates were associated with lower socio-economic deprivation (P<0·01), the proportion of the population aged 25–44 years (P<0·01) and fresh food outlet density (P<0·76). The results underline the role of area-level characteristics in explaining the spatial distribution of campylobacteriosis in New Zealand. In particular, the findings draw attention to the relatively unexplored role of fresh food outlets as a potential risk factor for increased Campylobacter notifications.

Attachment Dimensions

This study aimed to explore the relationships between attachment styles, proximity, and relational satisfaction. This was achieved by assessing a distinct type of long distance romantic relationship of flying crews, compared with proximal (non-flying crew) romantic relationships. The responses of 139 expatriate professionals revealed significant associations between proximity and anxious and avoidant attachment dimensions. The role of the avoidant dimension in comparison with that of the anxious dimension was found to be a significant predictor of relational satisfaction. This study contributes significantly toward addressing the role of proximity and attachment in relational satisfaction in a new context of geographic separation.

This paper reports part of an ongoing study exploring the information behaviour of New Zealand men during periods of diminished health and wellbeing. Focus groups were used for this iteration of the study. Results indicate that New Zealand men face both personal and structural constraints to their information-seeking during periods when their health and wellbeing may be compromised. This study highlights that service providers need to develop more effective information delivery mechanisms and support services for men. These services need to be appealing to men and reflect men’s information seeking preferences. The role of LIS professionals in supporting this endeavour is discussed. Cet article présente une étude en cours explorant le comportement informationnel d’ hommes néo-zélandais durant des périodes où leur état de santé et de bien-être est amoindri. Des groupes de discussion ont été utilisés pour cette itération de l'étude. Les résultats indiquent que les hommes en Nouvelle-Zélande font face à des contraintes à la fois  personnelles et structurelles dans leur recherche d'information pendant les périodes où leur santé et leur bien-être peuvent être affaiblis. Cette étude met en évidence le besoin pour les fournisseurs de services de développer des mécanismes de diffusion de l'information plus efficaces et des services de soutien pour les hommes. Ces services doivent être attrayants et refléter les préférences des hommes dans leurs recherches d’information. Le rôle des professionnels de l'information dans le soutien à cette entreprise est discuté.
