title: Bioerosion on shore platforms developed in the Waitemata Formation, Auckland

authors: Healy, Terry R.

subjects: Auckland

abstract: Bioerosion - the removal of lithic substrate by the erosive activities of living organisms- has not previously been discussed for New Zealand shore platforms. This paper aims at drawing attention to bioerosion as a process active in shore platform development. Detailed reference is made to bioerosion occurring on the alternating sandstones and siltstones of the Waitemata Formation found outcropping on the coastline around Auckland. In this area several facets of shore platform morphology may be attributed to the direct effects of boring and browsing marine organisms. A classification of animals causing bioerosion, based on mechanism of erosion, is presented, and the geomorphic significance of the various groups discussed.

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: Indigidata Aotearoa post-event summary report 2023

authors: Te Kotahi Research Institute

subjects: Indigenous Data Sovereignty

abstract: From the 21st to the 24th of August, the inaugural Indigidata Aotearoa 2023 was held at Te Whare Wānanga o Waikato. In recent years there has been significant advances in the fields of Indigenous data science and sovereignty. The Indigidata Aotearoa programme was designed to develop an understanding of Indigenous data science and sovereignty alongside some of the best researchers in Aotearoa New Zealand. The fully funded wānanga was open to Māori (tauira, kaitiaki, kaipakihi) participants from across Aotearoa. Applications were received from more than 35 respondents, and 23 tauira Māori attended the inaugural event.
