title: Are botanical gardens a risk for zooplankton invasions?

authors: Duggan, Ian C.

subjects: botanical gardens

abstract: A number of zooplankton invasions have been linked with the movement of plants to botanical and other public gardens. Although most of these records are historical, several recent examples indicate that aquatic fauna may still be transported by plant movements among gardens, or that there are unrecognised long-standing established populations in garden ponds around the world. We sampled 40 ponds from 10 gardens, in the United Kingdom and United States, to determine whether there is a high prevalence of non-indigenous zooplankton in garden ponds that could spread more widely if provided opportunity. No non-indigenous species were recorded from any of the gardens visited. We conclude that most well-established gardens do not pose a major threat for zooplankton invasions, mainly due to the destruction of ponds and associated populations through time, which apparently occurs commonly. In addition, ponds are regularly cleaned, insecticides are used on plants that may enter the water, and small fish are frequently added to conservatory ponds, further reducing the probability of zooplankton survival. Extirpation of populations may be occurring at a greater rate than re-introduction, due to greater restrictions on movement of plants, while the increasing focus on ex-situ conservation and science rather than aesthetics by botanical gardens means that fewer aquatic plants are being moved.

title: The Video Journal and visual pedagogies: in the age of visual cultures [Editorial]

authors: White, Elizabeth Jayne

abstract: Michael Peters and Jayne White introduce their thinking behind the development of the journal at the inaugural conference of the Association for Visual Pedagogies in Zagreb, June, 2016. They set the scene and pohilosophical parameters for a broad and forward-looking interpretation of visuality and the rise of visual studies by establishing an expanded route for the location of video Pedagogies in educational spaces. The video journal is introduced as a third generation form of scientific communication after the print-based journal and the digital online journal. The concept of the journal as the cornerstone of the scientific enterprise has evolved as new media technologies have become available. Industrial media known for its broadcast functionality of one to the many now is being replaced and remediated with video and mixed media increasingly with an accent on responsiveness and interactivity. In the second part of the presentation forms of visuality are explored and new visualization methodologies are discussed. An agenda is established for the potential and possibilities for Video Journal for Education and Pedagogy as a theoretical, philosophical, sociological, methodological and pedagogical site for future scholarship.

title: 'Kōrero Tuku Iho': Reconfiguring Oral History and Oral Tradition

authors: Mahuika, Nepia

subjects: History

abstract: The studies of oral history and oral tradition each have their own distinctive bodies of literature and preferred methodologies, yet share significant overlaps that make them difficult to differentiate. For many indigenous peoples, oral histories and traditions are key to their their past, present, and future lives, and are rarely considered separate. This thesis examines the differences and similarities between the studies of oral history and oral tradition. It explores how these areas of research converge and diverge in form, politics, practice, and theory, and the extent to which they resonate within a specific ‘indigenous’ context and community.
The thesis draws on the life narrative interviews of four generations of Ngāti Porou descendents, the second largest tribal group in New Zealand, whose home boundaries extend from Potikirua in the north to Te Toka-a-Taiau in the south on the East Coast of the North Island. Drawing on these voices, this study offers a commentary on the form and nature of oral traditions and histories from an indigenous perspective, and explores the ways they converge and depart from ‘international’ understandings. An exploration of these intersections offers insights to the ways oral history and oral traditions might be reconsidered as distinctive fields of study. Reconfigured through an indigenous frame of reference, this thesis challenges scholars of both oral history and oral tradition to expand their conceptions. Likewise, it urges indigenous scholars to consider more deeply the work of oral historians and oral traditionalists to further enhance their scholarship. Moreover, this thesis revisits the intellectual and conceptual territory that names and claims oral history and oral tradition, and invites all those who work in these areas to develop a more extensive comprehension of the interconnections that exist between each area of study.
