title: Seasonal abundance of small cladocerans in Lake Mangakaware, Waikato, New Zealand

authors: Greenwood, Tracey L.

subjects: biology

abstract: The seasonal changes in the dynamics and life histories of the Cladocera in Lake Mangakaware, North Island, New Zealand, were studied over 19 months by sampling at weekly or 2-weekly intervals. Lake Mangakaware is a 13.3 ha polymictic lake with high nutrient status, low Secchi disc transparencies, and an unstable thermal regime. The four planktonic cladoceran species (Bosmina longirostris, B. meridionalis, Ceriodaphnia pulchella, and C. dubia) exhibited disjunct population maxima. Only B. longirostris was perennially present. All species exhibited low fecundities and low lipid content, indicating that food resources were limited and that competitive interactions and resistance to starvation were probably important in determining species success. Increases in body size in cooler seasons were unrelated to clutch size, giving further support for the view that available food was limited. These results are consistent with previous experimental findings that subtle differences in life history can determine seasonal success and the outcome of competition between similar species.

title: Effect of different operational regimes of Okere gates on the effectiveness of the Ohau Channel diversion wall in Lake Rotoiti

authors: Muraoka, Kohji

abstract: The Centre for Biodiversity and Ecology Research was requested by Environment Bay of Plenty (EBoP) to present model results that demonstrate the water flow implications of four different water level operational regimes in Lake Rotoiti. The aim was to quantify the proportion of nutrient-enriched Lake Rotorua water being transported from Ohau Channel around the diversion wall and into Lake
Rotoiti. Environment Bay of Plenty did not wish to compromise the effectiveness with which the wall diverted this nutrient-enriched water from Rotorua directly to the Kaituna River.

title: An old story, a new voice: Tertiary education in the Bay of Plenty region

authors: Amundsen, Diana Leigh

subjects: Bay of Plenty

abstract: In this article, I first critique neoliberal effects on the Aotearoa New Zealand tertiary education sector and then provide a close-up look at tertiary education in the Bay of Plenty region. Information is based on aspects of my doctoral research which was located across three tertiary education organisations comprising the Bay of Plenty Tertiary Education Partnership: The University of Waikato, Toi Ohomai Institute of Technology and, Te Whare Wānanga o Awanuiārangi.  The findings of this research examine connections across the partnership, delving into relevant aspects of universities, polytechnics and wānanga. I evaluate the historical, geographical, political and socio-cultural context of all three institutions. Lastly, I discuss campus connections between the partnership organisations. The emerging picture reveals an old story of expansion and growth with a new voice of tension between collaboration and competition in the face of a neoliberal education context. This article offers timely implications for contemporary and future University of Waikato campus connections and may appeal to academics, graduate students, policymakers and the general public.
