title: Water flow between Ohau Channel and Lake Rotoiti following implementation of a diversion wall.

authors: Hamilton, David P.

subjects: New Zealand

abstract: The water quality in Lake Rotoiti has become increasingly degraded since the 1950s. Water from Lake Rotorua, with elevated phytoplankton and nutrient concentrations, has entered Lake Rotoiti via the Ohau Channel. To help improve water quality in Lake Rotoiti, a constructed wall was completed in July 2008, to divert water from the Ohau Channel towards Okere Arm in Lake Rotoiti, with the objective to transport this water into the Kaituna Rivr instead of entering the main basin of Lake Rotoiti. This report has been produced in response to a request from the Rotorua Lake Technical Advisory Group to determine water velocities in the region of the constructed wall, in order to consider the effectiveness of the diversion.

title: Intersectional feminist and queer geographies: a view from 'down-under'

authors: Johnston, Lynda

subjects: Social Sciences

abstract: Despite rapid growth of geographies of genders and sexualities over the past decade, there is still a great deal of homophobia, transphobia, and heterosexism within academic knowledges. A queer and feminist intersectional approach is one way to highlight gendered absences, institutionalized homophobia and transphobia. To understand the diversity of genders and sexualities, feminist and queer geographers must continue to talk about, for example, genders (beyond binaries), sex, sexualities, bodies, ethnicities, indigeneity, race, power, spaces and places. It is vitally important to understand the way that genders and sexualities intermingle incommunity group spaces, rural spaces, and within indigenous spaces in order to push the boundaries of what feminist and queer geographers understand to be relevant sites of queer intersectionality. Reflecting on the production of queer and feminist geographical knowledges ‘down-under’ may prompt others to consider the way place matters to intersectional feminist and queer geographies.

title: A late-Holocene and prehistoric record of environmental change from Lake Waikaremoana, New Zealand

authors: Newnham, Rewi M.

subjects: Palynology

abstract: Further evidence in support of a late pre-European (Polynesian) settlement of New Zealand is provided by an 1850-year-long tephropalynological record from a remote region in New Zealand's North Island. The earliest unequivocally anthropogenic forest clearance is estimated from sedimentation rates to have occurred c. 375 14C years BP (c. ad 1523–1631), although the radiocarbon chronology, shown by tephrochron ology to be erroneous due to hard-water effects, suggested this occurred c. 900 years earlier. Delineation of the anthropogenic era, and the distinction between human activity and other agents of environmental change in the pollen/spore diagram, are supported by cluster analysis and detrended correspondence analysis. Two distinct phases of forest clearance are evident during the pre-European era, reflecting local changes either in population pressure or settlement patterns. We note that the lull between the two phases of forest clearance coincides with the maximum of the ‘Little Ice Age’ within the period c. late ad 1600s to early 1800s.
