Becoming a source for trusted conversations

Friday, August 23rd, 2024

One of my roles as a director is to provide a platform to present robust evidence-based information that can be used as intended. This could be for downstream development of novel tools to manage diseases, for understanding how our use of the land is influencing how were adapt to climate change or for challenging existing norms and practices.

Because my role gives me a birds-eye view of the rich information being generated by BA researchers, I feel accountable for making sure this information is found. But with the diminishing media presence and the proliferation of multiple sources of ‘information’, it is becoming increasingly difficult for people and communities to wade through what’s meaningful and trustworthy. How do our communities, stakeholders and rights-holders choose which sources to trust?

To be heard, researchers are increasingly relying on our own self-promotion, which if I’m honest, is not within my comfort zone. I mainly fear getting some finer fact or detail of a study wrong and in doing so undermining my credibility to advocate for that study and even causing that study to lose its impact. But I put my reluctance aside, because I believe that researchers should have a voice, we need to have a voice.

If I take a helicopter view over the current landscape of platforms and blogs, I wonder how we researchers and directors can contribute to the arena of ‘ideas’ and how we can support healthy conversations about new information through messages we convey. I want our messages to be evidenced-based as well as inclusive.

Examples of these kinds of messages can be found in recent publications in Science with Jason Tylianakis about teaching Indigenous knowledge in the classroom and Tahu Kukutai about Indigenous data sovereignty. The motivation for these publications was to re-open contentious conversations within the platforms provided by our peer review system. Flawed as it can be, peer review is still our most robust measure of quality. Tahu and I also took the opportunity to highlight an overlooked and ongoing historical issue that Indigenous communities and those working with them face when trying to exert sovereignty over their data. This is something that we as researchers in BA are learning to navigate.

The reactions to the Indigenous data sovereignty piece were predictable and unpredictable. Predicable in that some individuals were unmoved in their assertion that we were discrediting one or the other form of knowledge generation. What was unpredictable was the main audience that was captured by the media release we wrote to raise awareness of the issue through our publication. Māori media grabbed it, and we saw a lot of public interest and engagement. This was more engagement than we got from within the research community. Perhaps that is yet to come but it did highlight the different aspects of research that get celebrated by researchers themselves. In this example, and others similar examples I’ve seen, researchers celebrate the acquisition of new knowledge, and people outside of research celebrate information that reaffirms their values. This brings me back to what I’ve been pondering:

How we do, as researchers get our work to our intended audiences? Are researchers only interested in new knowledge? Do communities only celebrate information that reaffirms their values and reflects their voices? Or can information, regardless of what it is, be packaged in a way that resonates with the intended audience even if it might not be what they are used to engaging with?

My ongoing challenge will be identifying our audiences and the best mechanism to reach them.  How do we continue to have inclusive conversations?  Researchers need to recognise those challenges, take the opportunities as they present themselves and not be afraid to make mistakes in articulating information to audiences they are not used to speaking with, whether these audiences are inside or outside of academia. Not everyone gets it right the first time, and feedback can be harsh. But taking turns at being the messenger can help share the load and normalise research in everyday conversations.

I’ve made it a resolution to take a public stand on issues that resonate with my values and use my platform to highlight the amazing work that BA people are doing. I hope that others will take the leap and find their voices too.

Demystifying our fungi mātauranga

Thursday, August 22nd, 2024

Tere Porter-Rawiri (Te Ātiawa) is a master’s student in Ecology at Victoria University of Wellington researching the importance of fungi to Māori raised in Wairarapa, and mātauranga Māori about fungi more broadly with the purpose of characterising fungal community diversity in restored, pastoral, and conserved Wairarapa wetland forests. Here, Tere reflects on her initial findings midway through her thesis year.

I’m constantly amazed by how much more there is to learn and there are always more connections with what I already know about our taiao. Attending a Matariki talk focusing on Tupuārangi at Te Papa by Puke Timoti (Tūhoe) made me reflect on my research and how it has broadened my view of our forest ecosystems. Listening to these insights deepened my appreciation for the intricate relationship my tūpuna had with the environment.

It’s a bit emotional for me to imagine the abundance of kai my tūpuna must have experienced—the sights, sounds, and tastes—like heaps of kererū flying away to the point where the entire sky is left in a dark cloud of shadows, or the slapping sounds of many tuna kuwharuwharu on their heke from freshwater out to the sea to spawn. It makes so much sense why our tūpuna were so closely connected to te taiao, but it’s also remarkable to think about the level of fundamental knowledge and practices required to attain such abundance and sustenance. At its core, being closely connected to te taiao involves observing and recording details like temperature, weather patterns, the sun’s position, stars, and moon phases. It’s about being in tune with what other creatures are up to, like manu flying to specific areas at specific times for specific food sources, insects dwelling throughout the soil, microbes cohabiting a new environment. It’s about understanding the different plant and tree species and knowing their timings for fruiting, flowering, and seeding, plus their various connections to other species —which is the basis of creating a maramataka.

Tere Porter-Rawiri


But there’s also a part of being in tune to oneself and one’s emotions, understanding how our nervous system responds to the external world, and interpreting and making sense of the conditions around us. This forms the foundation of te ao Māori, where our observations of the environment are deeply embedded in te reo Māori.

We only have to look as far as Māori horticulture to reveal our expertise in cultivating crops, gardening, and soil science—so why wouldn’t we also be mycologists?

Mycologists study the science of fungi including taxonomy and genetics (or whakapapa), and biochemical properties, and uses by humans (such as tinder, tā moko, kai, and rongoā).

I started thinking about this during a kōrero with kaumātua Ra Smith (Ngāti Kahungunu ki Wairarapa) about any atua connected to fungi. There aren’t any that are formally documented atua connected to fungi (to my knowledge at least), but Ra thinks there would be one in a manuscript somewhere, he just hasn’t found it yet. We both acknowledged that fungi deserve a positive association in te ao Māori as they have nurturing characteristics in the way they co-exist with other beings. Fungi traverse the realms of te ao kikokiko (the physical world) and te ao wairua (the spiritual world) and it is likely that our tūpuna understood what was occurring despite the fact that fungi and the work they do are mostly unseen.

Fungi have important ecological roles which bridge these two realms through nutrient cycling and as decomposers in the soil and on trees. When trees come together as a network or grove with the help of our native endemic mycorrhizal fungi that grow on and in the tips of their roots, we know they are taonga as they enable our trees to provide bountiful food for our manu and materials for carvings, tools, and snares. When mushrooms grow on a tree, signalling its end of life, this likely served as a significant visual indicator of ecosystem wellbeing. Because of these important ecological roles, which are also culturally significant, it makes sense that the atua of fungi would likely be a wāhine, especially considering what we know about our female atua—like Hine-ahu-one, Hine-nui-te-pō, Papatūānuku, and Hine-te-iwaiwa. These atua are associated with land, earth, clay, and soil, which give life and also represent death and darkness.

This is an example of how whakapapa is fundamental to our understanding of how different reference points are layered to comprehend our genealogy, actions, behaviours, and sequential systems which also link to encompass our obligations to the environment, both tangible and intangible.

Interpreting our mātauranga in this way recognises that mātauranga is interlinked with practice and never exists in isolation. Examining what we already know allows us to make inferences about our fungi mātauranga. My ‘insights’ build on our existing understandings, offered in a different light to encourage a richer appreciation of our physical environment and extending this to include the many knowledge systems connected to it.

Native forests on farms could store the most soil carbon

Thursday, August 8th, 2024

Postdoctoral Fellow Dr Alexa Byers


Greater biodiversity above ground is widely considered the key to healthy landscapes, but does this presumption hold up beneath our feet? Postdoctoral Fellow Dr Alexa-Kate Byers (Lincoln University) looked at the diversity of carbon-munching microbes beneath different land uses and what this could mean for carbon storage in the soil. 

Our soils act as vital reservoirs for carbon, but when soil microbes break down the organic matter around them, then respire, they release carbon to the atmosphere as a gas.  

To investigate the effect of different land uses on these microbes, Alexa and her team sampled the soil beneath five different land uses around Kaituna and Prices Valley in Canterbury. 

She says “We really wanted to measure how land use change altered the way in which soil microbes process soil carbon, as this has important implications for long-term soil carbon storage.” 

“Microbial ecology is still a relatively new field compared to plant ecology. A lot of the presumptions we make about microbial diversity are based on patterns in the research we’ve done above ground . . . but one of the things I found in this study is that’s not always the case.” 

After testing soil below remnant native forest, regenerating native bush, exotic plantation forest, dryland pasture and irrigated pasture, Alexa discovered the diversity of carbon-munching microbes increased proportionally with the disturbance of the land above ground. That means agricultural land uses were associated a greater range of microbial genes. 

This isn’t a ‘bad thing’ per se, but it does mean that these soils could store less carbon than those under regenerating or mature native forest. 

Alexa says “Agricultural land uses have a huge productive value and are important for food production; this research isn’t about assigning land uses into good or bad categories. But it’s important to be aware of the potential consequences of human activity on the soil”.   

“Incorporating more different types of land uses into the same area could allow agriculture and store carbon in the soil at the same time. This would also be beneficial for other values we might have, like cultural or above-ground biodiversity.”  

While her sample sites were restricted to Canterbury, Alexa is confident that the results are relevant to land managers throughout the country.

Emerging scientist propelled into international recognition

Tuesday, August 6th, 2024

Postdoctoral fellow Dr Nils Birkholz (University of Otago) presenting his work on bacteria-fighting viruses.


A team of New Zealand scientists has published research in the renowned international journal, Nature, after collaborating far and wide to tell the story of a microscopic arms race. 

First author, Postdoctoral fellow Dr Nils Birkholz (University of Otago) studies bacteria-fighting viruses called phages, which are being widely considered as the next step to controlling antibiotic-resistant bacteria in food production and human health. 

This new research paper focuses on the expression of genes that occur when a phage infects a bacterium. 

Nils says “Helix-turn-helix domain proteins were already well-known to be involved in gene regulation, but we found that one particular member of this protein family has a very interesting new mode of regulating gene expression.” 

The paper describes how these proteins help the phage keep bacterial defences in check through multiple layers of regulation.

There are many other proteins in the helix-turn-helix family that Nils says may have similar mechanisms that have been overlooked, and this finding might prompt other researchers to take another look at their role in gene regulation. 

“In the context of using phages in agriculture to fight plant pathogens, this research will hopefully contribute to that. But our discovery of a new mechanism of gene regulation is especially interesting for fundamental research.” 

Nils thinks publishing in such a prestigious journal was thanks to the collaborative approach the team took once they had the first results. 

“We reached out to other research groups to see how we could increase the impact of the story,” he says, “Now we have lots of different methods in it, and I think that is one of the aspects that made it so interesting for a journal like Nature. 

“It was definitely quite challenging to combine all these diverse contributions together, but it was worth it.” 

Project director Professor Peter Fineran (University of Otago) helped pull in scientists from Germany, USA, the UK and New Zealand to contribute to the research. 

Peter says having “more than a rugby team” of authors all working on one project is a stark contrast to how scientists did things when he was early on in his career. 

“It was more the old way of doing things which was more ‘your PhD is your project’ . . . you would have to learn every new technique you wanted to use. Collaboration means you can get much more impactful, interdisciplinary science done.” 

“This publication is a great outcome,” Peter says, “The world is Nils’ oyster now. This will open up many exciting career opportunities for him.”  

Nils hopes the international stage will see this research inspire other scientists, whose work can build on the different aspects of their new publication.

How do farmers’ values and priorities affect biodiversity?

Monday, July 15th, 2024

Postdoctoral Fellow Elizabeth Elliot Noe, researches the values and priorities of farmers in relation to biodiversity on farms


Farming is a critical lever in protecting biodiversity in Aotearoa New Zealand because over half of our land area is farmed, and much native biodiversity resides there. Protecting and enhancing this biodiversity largely relies on farmers voluntarily adopting biodiversity-supporting farming practices, making the value farmers place on biodiversity crucial.

Postdoctoral researcher Elizabeth Elliot Noe set out to explore farmers’ values and priorities by conducting interviews with 20 farmers in Waikato and Canterbury. Her goal was to understand the experiences, meanings, relationships, values, and priorities dairy farmers have for their land and the implications for native biodiversity on farms.

Over a chat at the kitchen table or in the milking shed, she asked the farmers to explain what aspects of native biodiversity were desirable or even possible on their farms. She then followed them out onto the farm to see examples of what they’ve done to protect biodiversity.

Elizabeth says she heard a range of perspectives, but overall, most dairy farmers she spoke with didn’t see a connection between biodiversity and the productivity of their farm. However, many farmers did see ways biodiversity could help with other important aspects, such as aesthetics, shade, shelter, and animal welfare.

As a result, many of the farmers were open to protecting biodiversity in areas that aren’t productive, such as on slopes and in wet areas. They were, however, almost unanimously opposed to using productive land for anything but agriculture.

Elizabeth acknowledges that farmers are not a homogenous group, and some value biodiversity more highly than others. She explains that the theory of value hierarchies recognises that we all have limited time and resources, so we put energy into the things that are most important to us.

Presenting her findings directly to the communities where her interviewees resided, Elizabeth’s talks were well-received. In attendance was lifestyle-block farmer and tree nurseryman Graeme Cairns from Hamilton, who was particularly surprised by the high proportion of native vegetation on pastoral land, far exceeding his expectations.

Mr Cairns says, “For an academic piece … the guts of it was quite insightful.” He felt the research could serve as an excellent resource for those looking to develop action plans to engage farmers who prioritise “every blade of grass lost is money out of my pocket.”

For some farmers, biodiversity simply isn’t a priority given the many other pressures they face. However, some farmers do value biodiversity more highly, and they are therefore willing to contribute time and resources to protect it.

Elizabeth’s study also highlights that whereas farmers once only had to worry about maximising productivity, they now must juggle many competing pressures and challenges. These include new policies, large amounts of paperwork, and negative public perceptions about the role of farming in water quality and climate change.

Elizabeth’s next step is to discuss these challenges with a wide range of dairy industry experts with diverse perspectives and expertise – including DairyNZ, Synlait, NIWA, and other policy experts. This work will highlight the many ways to think about dairy farming in Aotearoa New Zealand and outline the diverse approaches farming could take.

When Weeds Unite

Tuesday, May 7th, 2024

Diana Borse pulling out brush wattle


What happens when you mix woolly nightshade (Solanum mauritianum), brush wattle (Paraserianthes lopthantha), and tree privet (Ligustrum lucidum) with native plants from Aotearoa New Zealand?

You might think it’s a weedy good time, but Diana Borse, a PhD student from the University of Auckland, is delving into the intricate world of weed ecology to find out. She’s investigating how these weeds interact with native plants in our natural ecosystems.

Despite the stigma often associated with weeds, Diana sees an opportunity to explore their ecological roles and interactions. “Understanding the background of weed invasion in Aotearoa New Zealand, I saw an opportunity to delve deeper into their ecological roles and interactions,” says Diana.

In the field of weed ecology research, there has been limited studies investigating the coexistence of multiple weed species. Diana adds “most studies focus on single weeds, but in reality, land managers deal with multiple species.”

Methodical Approach: From Field to Shade House

To investigate the patterns of co-occurrence among these weeds, Diana is using both real-world fieldwork and controlled shade house experiments, aiming to identify signs of facilitation or competition among plant species.

“I conduct circular plots around specific weed species to assess their impact on surrounding vegetation,” Diana explains. “These 4m2 circular plots, are centred around mature weed species such as woolly nightshade, tree privet, or brush wattle.”

For comparison, Diana pairs each weed plot with a mature native species, to understand the impact of the site versus the specific plant species. “I measure attributes such as canopy cover and litter depth, to account for environmental factors influencing plant growth.”

From 180 plots measured, preliminary data analysis has already revealed emerging patterns, particularly regarding the influence of brush wattle on the presence of other weeds.

“Brush wattle shows a higher proportion of weed seedling beneath its canopy than native or woolly nightshade centred plots.” This emerging pattern has Diana hypothesising that there might be some facilitation going on.

“Brush wattle is a nitrogen fixer, so it could be adding nitrogen to the system, facilitating grown and establishment for the riskier weeds.”

Diana adds that more data is required to validate whether this pattern is actually causation rather than correlation. “Combining this emerging pattern with our shade house experiments, could show something really interesting”.

Diana’s shade house experiment includes 1000 plant specimens.


Shade House Experiments

Diana’s shade house experiments have been designed to explore the intricate dynamics between weeds and native species with a focus on determining whether their interactions yield additive or non additive effects.

Under carefully controlled conditions, Diana has planted the different combinations of weed species alongside native plants, aiming to understand the nuanced dynamics of their coexistence in these experiments.

The native plant Diana is using is Mānuka, sourced from Pourewa nursery of Ngāti Whātua Ōrākei. Her methodological approach involves monthly measurements of plant growth, assessment of soil conditions, and monitoring each species.

Diana’s research also extends beneath the surface, looking at the root systems, analysing samples to decipher mycorrhizal colonisation, and soil interactions.

The shade house experiments are conducted in two phases, beginning with the growth of Mānuka seedlings in the presence of various weed combinations. Simultaneously, Diana is growing another batch of Mānuka plants in pots with different weed combinations, to prepare for her next phase of experiments.

“After the first shade house experiment ends, I’ll then remove one of the weeds and then keep them growing to see how that affects the remaining Mānuka and then also the remaining weeds.”

Managing a total of 1000 plant specimens, Diana faces challenges including pests, transplant issues, and the survival of brush wattle.

“Brush wattle has been a nightmare. I’ve collected probably 1,500 brush wattle at this point to have 200 surviving.” Seeking advice, Diana has actively managed this issue by adjusting her potting mix, selecting different collection sites of weeds, and proactively replacing weeds which have died.

Data Analysis and Potential Impacts

As part of her broader research efforts, Diana is analysing Auckland Council data on weed occurrences in residential areas bordering reserves. This analysis provides insights into the spread of these weeds and the effectiveness of current management practices.

“So, by combining fieldwork with the analysis of the dataset from the Auckland Council, we aim to develop more effective strategies for managing invasive plant species like brush wattle.”

With her PhD expected to end by September 2025, Diana’s research is well on its way to making significant contributions to both scientific knowledge and environmental management practices.

By clarifying the mechanisms driving invasive species dynamics and proposing evidence-based management solutions, her work promises to enhance ecosystem resilience and promote biodiversity conservation in Aotearoa New Zealand.
