A number of scholars in the Asia-Pacific region have in recent years pointed to the importance that cultural values play in influencing journalistic practices. The Asian values debate was followed up with empirical studies showing actual differences in news content when comparing Asian and Western journalism. At the same time, such studies have focused on national cultures only. This paper instead examines the issue against the background of an Indigenous culture in the Asia-Pacific region. It explores the way in which cultural values may have played a role in the journalistic practice of Māori journalists in Aotearoa New Zealand over the past nearly 200 years and finds numerous examples that demonstrate the significance of taking cultural values into account. The paper argues that the role played by cultural values is important to examine further, particularly in relation to journalistic practices amongst sub-national news cultures across the Asia-Pacific region.

Social system-level analyses of journalism have tended to focus on political and economic influences, at the expense of other factors, such as the role that culture and cultural values play in shaping journalists' professional views and practices. This paper identifies cultural values as a particularly fruitful area for providing a more nuanced analysis of journalism culture. It examines this issue in the context of in-depth interviews with 20 M?ori journalists from Aotearoa New Zealand. The study finds that Indigenous journalism in that country is strongly influenced by M?ori cultural values, such as showing respect to others, following cultural protocols, and making use of culturally-specific language. Cultural limitations are also identified in the form of the social structures of M?ori society, and journalists' strategies in working around these are discussed. The paper highlights the implications a renewed focus on cultural values can have for the study of journalism culture more broadly.

ori food sovereignty was and continues to be severely affected by British colonisation and influence. This situation and its causes, both past and present, will be examined in the context of Māori culture, especially Te Tiriti, a founding document of New Zealand. The general concept of food sovereignty is introduced, and its key principle: having power over one's own food system. A brief history of Māori food systems is necessary as context–their adaptation from Polynesia to New Zealand and later, to European settlement. Te Tiriti and the Treaty of Waitangi are explained: how they were created and why Te Tiriti is authoritative. Then, different aspects of Te Tiriti are linked to various parts of Māori food sovereignty and traditional Māori concepts. Through breaching tuku whenua in Te Tiriti, land issues have arisen: the methods used to confiscate Māori land and the effects this had on traditional food, health and urbanisation are discussed. Culture as taonga is examined: the ways in which losing a food system leads to losing traditions, and how this breaches Te Tiriti. Then the (mostly negative) effects of this shift in food systems on the environment is examined, and how this relates back to taonga as well as the traditional duty of kaitiakitanga and, again, the breaching of Te Tiriti. Lastly, the underlying issue of power is examined in relation to rangatiratanga and overall sovereignty–this is also linked to Te Tiriti.

The aim of the study was to establish and verify a predictive vegetation model for plant community distribution in the alti-Mediterranean zone of the Lefka Ori massif, western Crete. Based on previous work three variables were identified as significant determinants of plant community distribution, namely altitude, slope angle and geomorphic landform. The response of four community types against these variables was tested using classification trees analysis in order to model community type occurrence. V-fold cross-validation plots were used to determine the length of the best fitting tree. The final 9node tree selected, classified correctly 92.5% of the samples. The results were used to provide decision rules for the construction of a spatial model for each community type. The model was implemented within a Geographical Information System (GIS) to predict the distribution of each community type in the study site. The evaluation of the model in the field using an error matrix gave an overall accuracy of 71%. The user's accuracy was higher for the Crepis-Cirsium (100%) and Telephium-Herniaria community type (66.7%) and relatively lower for the Peucedanum-Alyssum and Dianthus-Lomelosia community types (63.2% and 62.5%, respectively). Misclassification and field validation points to the need for improved geomorphological mapping and suggests the presence of transitional communities between existing community types.

Aim The aim of this study was to explore the environmental factors that determine the spatial distribution of oro-mediterranean and alti-mediterranean plant communities in Crete. Location The paper provides a quantitative analysis of vegetation-environment relationships for two study areas within the Lefka Ori massif Crete, a proposed Natura 2000 site. Methods Eleven environmental variables were recorded: altitude, slope, aspect, percentage of bare rock, percentage of unvegetated ground, soil depth, pH, organic matter content and percentages of sand, silt and clay content. Classification of the vegetation was based on twinspan, while detrended correspondence analysis (DCA) and canonical correspondence analysis (CCA) were used to identify environmental gradients linked to community distribution. Results One hundred and twenty-five species were recorded from 120 plots located within the two study areas. Forty-seven of the recorded species are endemic, belonging to 35 families. Hemicryptophytes and chamaephytes were the most frequent, suggesting a typical oro-mediterranean life form spectrum. The samples were classified into five main community types and one transitional. The main gradients, identified by CCA, were altitude and surface cover type in the North-west site, while in the Central site the gradients were soil formation-development and surface cover type. Main conclusions The use of classification in combination with ordination techniques resulted in a good discrimination between plant communities and a greater understanding of controlling environmental factors. The methodology adopted can be employed for improving baseline information on plant community ecology and distribution in Mediterranean mountain zones.

The aim of this study is to analyse the vascular flora and the local climate along an altitudinal gradient in the Lefka Ori massif Crete and to evaluate the potential effects of climate change on the plant diversity of the sub-alpine and alpine zones. It provides a quantitative/qualitative analysis of vegetation-environment relationships for four summits along an altitude gradient on the Lefka Ori massif Crete (1664-2339 m). The GLORIA multi-summit approach was used to provide vegetation and floristic data together with temperature records for every summit. Species richness and species turnover was calculated together with floristic similarity between the summits. 70 species were recorded, 20 of which were endemic, belonging to 23 different families. Cretan endemics dominate at these high altitudes. Species richness and turnover decreased with altitude. The two highest summits showed greater floristic similarity. Only 20% of the total flora recorded reaches the highest summit while 10% is common among summits. Overall there was a 4.96 degrees C decrease in temperature along the 675 m gradient. Given a scenario of temperature increase the ecotone between the sub-alpine and alpine zone would be likely to have the greatest species turnover. Southern exposures are likely to be invaded first by thermophilous species while northern exposures are likely to be more resistant to changes. Species distribution shifts will also depend on habitat availability. Many, already threatened, local endemic species will be affected first.
