Production of beef-cross-dairy calves from dairy cows increases the value of non-replacement calves born to the dairy herd. The use of beef-breed sires may impact on calf birth weight, gestation length and pre-weaning growth rate of calves, which in turn influences the profitability of the dairy farm. The aim of this case study was to compare the birth weight, gestation length, and pre-weaning growth of progeny born to mixed-aged dairy cows on a single farm which were artificially bred to a selection of Angus and Hereford bulls, typical of those used over dairy herds in New Zealand. The birth weight, gestation length and pre-weaning growth of 980 calves sired by 65 sires were compared. Mean progeny birth weight (range 33.3–41.4 kg), gestation length (range 276.1–288.6 days), age at weaning (range 70.3–88.3 days) and pre-weaning ADG (range 0.63–0.76 kg/d) differed among sires (p < 0.001). There was a negative genetic correlation (−0.31) and positive phenotypic correlation (0.36) between gestation length and birth weight. Age at weaning was negatively correlated with birth weight (genetic: −0.56, phenotypic: −0.57). Bulls used in this study, and other bulls with similar genetic merit for birth weight and gestation length would be suitable for mating mixed-aged dairy cows in New Zealand.

<p>Over the past few years, there has been increasing attention in New Zealand drawn to the pollution of water bodies from dairy farm effluent, and ways to mitigate this. The aim of this research is to identify the key elements involved in engaging farmers in community based action to mitigate agricultural water pollution. The study examines a Landcare project that has shown signs of apparent success, entitled the Aorere Catchment Project (ACP), in Golden Bay, New Zealand. The ACP was initiated after the Aorere River was found to have high pathogen levels, likely resulting from dairy farm runoff. This research evaluates the projects apparent success, and follows the evolution of the project to gain an understanding of the key success factors in engaging farmers. Surveys of dairy farmers in the Aorere valley were undertaken in 2007 and again in 2010 to identify management practices and identify changes in issues and farmer attitudes over this period. This study found that the ACP has had extensive success, both in resolving waterway issues and engaging farmers in action for healthy waterways. The underlying community led philosophy of the project has been vital in the success of this project. The key project principles, ‘farmers as leaders’, and ‘experts on tap not on top’ have contributed greatly to the projects uptake. There are however some catchment specific elements that have aided the apparent success of this initiative. The Aorere catchment project model unchanged would not be suitable for every catchment in New Zealand, as not all the elements of success were under the projects control. The model does however serve as a good example for similar projects in other New Zealand catchments, and also the importance of a suitable indicator of success.</p>

William Smyth, unable to get work in a New Zealand museum, ran a commercial taxidermy business at Caversham, Dunedin, from about 1873 to 1911 or 1912. His two decades of correspondence with Thomas Frederic Cheeseman at the Auckland Museum provide a case study of Smyth's professional interaction with one of New Zealand's main museums. We have used this and other sources to paint a picture of Smyth's activities and achievements during a time when there was great interest in New Zealand birds but few local taxidermists to preserve their bodies. Besides the Auckland Museum, Smyth supplied specimens to various people with museum connections, including Georg Thilenius (Germany) and Walter Lawry Buller (New Zealand). Smyth was probably self-taught, and his standards of preparation and labelling were variable, but he left a legacy for the historical documentation of New Zealand ornithology by the large number of his bird specimens that now reside in public museum collections in New Zealand and elsewhere.

The rights-of-nature model is gaining traction as an innovative legal approach for nature conservation. Although adopted in several countries, it remains in its infancy, including in Australia. An important research question is whether rights of nature will offer superior environmental outcomes compared to traditional nature conservation techniques including creation of protected areas. This article investigates that question through a case study of the Tarkine wilderness, in the Australia state of Tasmania. It first identifies key lessons from existing international experience with affirmation of rights of nature, such as in New Zealand and Ecuador. The article then explores how rights of nature could apply in Australia’s Tarkine region and their value compared to existing or potential protected areas and other nature conservation measures under Australian or Tasmanian law. Affirming rights of nature represents a major conceptual shift in how people via the law relate to the natural world, but whether the model offers practical benefits for nature conservation depends on a variety of conditions, in addition to the need to address broader societal drivers of environmentaldegradation.

Purpose The purpose of this paper was to explore how small immigrant communities in host countries collect, disseminate and present information about their home country and their community, and the role of formal societies and clubs in it. Design/methodology/approach This paper presents the results of a case study of the Croatian community in New Zealand. To illustrate how cultural and technological changes affected information dissemination and communication within the community, the case study presents both historical and current situations. Methods used in this case study included a content analysis of historical newspapers published in New Zealand by the Croatian community, content analysis of current webpages and social networking sites, and interviews with participants who have management roles in Croatian societies and communities in New Zealand. Data were collected from December 2018 to February 2019. Findings Formally established clubs and societies, but also informal groups of immigrants and their descendants can play a significant role in providing their members with information about the culture, social life and events of the home country. They also play a significant role in preserving part of the history and heritage which is relevant, not only for a specific community but also for the history and culture of a home country. Originality/value The methodology used in the research is based on data from community archives and can be used for studying other small immigrant communities in New Zealand or abroad. The case study presented in the paper illustrates how the information environment of small immigrant communities develops and changes over the years under the influence of diverse political, social and technological changes.
