Members of the EcoDiv lab
Group leader
Dr Andrew Barnes
I am a Senior Lecturer at the University of Waikato and head of the EcoDiv lab group. I am broadly interested in the impacts of global change drivers on natural systems and the resulting functional consequences. My research focuses on how environmental changes alter the seemingly complex relationships between biodiversity, the structure of communities, biotic interactions, and ecosystem functioning.
Postdoc
Dr Kasey Kiesewetter
Kasey is involved in the MBIE programme ‘Restoring Urban Nature’, where she is studying how urban restoration drives changes in below- and aboveground microbial networks, and how these changes might influence the health of humans and wildlife.
PhD student
Niamh Tapper
Niamh's research is aimed at understanding if and how global warming erodes the resistance and resilience of soil food webs to other climate disturbances like drought. She is using experimental rainout shelters to create an extreme drought event along a geothermal warming gradient to simulate a range of soil warming scenarios.
PhD student
Stella Brachmann
Stella is investigating the long-term reassembly of microbial biodiversity and ecosystem functioning. Using both metagenomic and meta-transcriptomic profiling, her research is exploring the role of stochastic and deterministic assembly mechanisms.
PhD Student
Estela Folch Chaos
Estela is carrying out research in a unique set of natural, geothermally warmed sites, where she is able to study the temperature dependence of soil food web structure and ecosystem functioning. She is combining field and lab experiments to determine how food webs will respond to future warming and land-use change.
Past members
PhD Student
Bibishan studied the re-assembly of belowground food-webs in urban forests across different stages of succession. Using a ‘food web energetics’ approach, he investigated changes in the structure and energy flux of soil food webs over the course of urban forest restoration across New Zealand.
MSc Student
Poppy investigated drivers of soil fauna and tree community structuring, using metabolic theory to predict and test the fundamental energetic constraints of multitrophic communities across local and global datasets.
PhD Student
Fevziye investigated how traits of introduced and native dung beetles affect biotic and abiotic drivers of ecosystem multifunctionality, at local and global scales.
Gemma studied the landscape drivers of invertebrate biodiversity and ecosystem services in avocado plantations. She used remote sensing to help understand how landscape structure can influence insect pollinator and pest communities.
René studied the energetic impacts of warming on pollinator behaviour and the provisioning of pollination services. She also investigated the allometric relationships between metabolism, temperature and pollinator behaviour.
MSc Student
Rebecca Booth
Rebecca investigated the effects of riparian vegetation on temperature, dissolved oxygen, and macroinvertebrate community structure and ecosystem functioning in low-gradient streams throughout the Waikato region.
MSc Student
Grace Mitchell
Grace studied the reassembly of microbial and mesofauna communities along an urban forest restoration chronosequence.
Postdoc
Dr Rebecca Le Grice
Rebecca investigated soil invertebrate food webs associated with Aotearoa’s iconic kauri, and the impact that kauri dieback (Phytophthora agathidicida) may be having on this ecosystem. This work is part of the programme Ngā Rākau Taketake – Saving our iconic trees, within the BioHeritage Challenge
PhD Student
Nigel Binks
Nigel investigated how invasive mammalian predators affect forest soil arthropod communities and the transboundary effects on belowground arthropod biodiversity in adjacent pasture soils.
MSc
Shaun Morgan
Shaun's MSc research explored how invasive mammal control interacts with fragment size and isolation to affect the abundance of invasive mammalian predators and the resulting impacts on native bird communities in the North Island, New Zealand.
Postdoc
Dr Marijke Struijk
Marijke's postdoc was part of the BioHeritage Challenge programme Ngā Rākau Taketake – Saving our iconic trees. She investigated the impact of kauri dieback (Phytophthora agathidicida) on soil invertebrate food webs.
