title: Trade and Climate Change - Tracing the Conflict between Trade and Climate Change Reform and Plotting a Mutually Supportive Route Forward

authors: Rowland, James

subjects: trade law

abstract: This thesis looks at the individual importance of trade and climate change reform, the relationship between these two areas, and then identifies some of the trigger points that may cause conflict between trade law and climate change measures. Once those areas of tension have been identified, this thesis plots a way forward in attempting to resolve those selected conflicts, ultimately suggesting that the Appellate Body should take mutually supportive interpretations when finding themselves dealing with a conflict between WTO law and climate change reform measures.

title: Size matters: implications of the loss of large individuals for ecosystem function

authors: Norkko, Alf

subjects: ecosystem ecology

abstract: Size is a fundamental organismal trait and an important driver of ecosystem functions. Although large individuals may dominate some functions and provide important habitat structuring effects, intra-specific body size effects are rarely investigated in the context of BEF relationships. We used an in situ density manipulation experiment to explore the contribution of large, deep-burrowing bivalves to oxygen and nutrient fluxes across the sediment-water interface. By manipulating bivalve size structure through the removal of large individuals, we held species identity constant, but altered the trait characteristics of the community. The number of large bivalves was the best predictor of ecosystem functioning. Our results highlight that (a) accounting for body size provides important insights into the mechanisms underpinning biodiversity effects on ecosystem function, and (b) if local disturbances are recurrent, preventing individuals from reaching large sizes, the contribution of large adults may be lost, with largely unknown implications for ecosystem functionality.

title: The first accurate and precise calendar dating of New Zealand Māori Pā, using Otāhau Pā as a case study.

authors: Hogg, Alan G.

subjects: Māori pā

abstract: This research investigates the potential of radiocarbon wiggle-match dating of palisade posts to provide precise and accurate calendar ages for Māori pā (forts), using Otāhau Pā in the inland Waikato region, New Zealand, as a case study. Even though pā are a dominant element of the pre-European North Island archaeological landscape, they are poorly understood archaeologically, with systematic investigations hampered by the relative lack of precision in radiocarbon dating within the context of New Zealand’s comparatively short prehistory. Using the Southern Hemisphere calibration curve SHCal13, we determine wiggle-match calibrated ages for three palisade posts, using different sampling resolutions to determine the cost- effectiveness of the method. We also test the accuracy of the wiggle-match by obtaining new Southern Hemisphere calibration data from known calendar-age kauri.
