Pekapeka, how we shape their world and they shape ours

Pekapeka are the only native land mammals in Aotearoa New Zealand, yet they are relatively unknown by the general public, perhaps because they are small, rare, nocturnal, and cryptic. This means that bats have sometimes been overlooked in the past, but this is changing.  We hope to highlight in this symposium recent research that focuses on the relationships we hold with pekapeka, how we are shaping their world, making it more or less palatable for them, and areas for future research.

Tākiri te ata – Mātauranga Māori and Ecology

Mātauranga Māori plays a key role in the protection and care of nature here in Aotearoa. It serves as a basis for Māori communities to understand their surrounding environments and develop strategies and processes to protect and care for these important spaces and the living species within them. Growing challenges for the protection and care of nature as well as opportunities for Māori to express and maintain relationships to their ancestral lands, waters and territories continues to progress in Aotearoa. There is ample opportunity to showcase the value of Mātauranga Māori and ecological science in addressing such challenges, protecting nature, whilst also supporting Māori to enact their kaitiakitanga roles of te taiao. This symposium will showcase the value of bridging both Mātauranga Māori and Ecology in addressing pressing environmental issues here in Aotearoa.

How Invasions Misshape Our World

Biological invasions represent one of the greatest environmental and economic threats to Aotearoa New Zealand. Invasive species are more than simply misplaced individuals – in many cases they fundamentally alter the environments in which they’re introduced, permanently affecting the functioning of ecosystems and susceptibility to further invasions. These effects can range from changing soil types and introducing mutualistic fungi or bacteria, altering important ecosystem functions (e.g., nutrient removal), creating or destroying habitats (ecosystem engineering), and altering species’ behaviours to facilitate future invasions. Even our own methods to eradicate invasives can inadvertently lead to highly degraded ecosystems which are more prone to successive invasions.

This symposium aims to highlight how invasive species affect the world beyond simply outcompeting competitors. Here we will discuss how and why environments become misshapen, and how this can lead to even worse re- or successive invasions in the future. We encourage talks from a range of systems including terrestrial, freshwater, and marine environments.

Ecology in a Post-Truth World

Over the last decade mis-, dis- and mal-information have skyrocketed to unprecedented levels. While some sciences are affected more by conspiracy theories than others, all public facing sciences fall victim to bullying, harassment, and public opposition from a few (but loud) opponents. Ecology is one such discipline that struggles to engage small factions of the general public in scientifically valid solutions. Climate change immediately comes to mind as an example of a huge global ecological issue that is hampered by denialism and troubling political debates. However, Aotearoa New Zealand faces a number of its own concerns such as 1) Ban-1080, 2) Kauri Forest Closure Protests, 3) Marine Exclusion Zones / Fishing Bans, and 4) 15-minute cities and “climate lockdowns”. Disputes can range from rational debate to irrational conspiracy theories, but regardless require us to focus on the facts, and develop effective science communication techniques.This symposium aims to highlight examples of ecological science denialism (or serious debate) in Aotearoa, and crucially gives preference to talks that highlight case studies demonstrating effective solutions or examples of successfully engaging with difficult-to-please stakeholders.

Ecological Impacts of Tropical Cyclones

Climate change is altering the frequency and intensity of extreme weather events, with Aotearoa New Zealand projected to experience stronger and more frequent tropical cyclones in the future. The ecological consequences of these events can be extensive and long-lasting, yet we still lack fundamental knowledge of the ecosystems, species, and conservation infrastructure that are most at risk, and how management actions influence post-disturbance recovery.

This symposium brings together recent research on tropical cyclone ecology, with a special focus on the ecological impacts of Cyclone Gabrielle, which hit Aotearoa New Zealand with devastating force in February 2023. Talks will cover a diversity of topics, including the history of cyclones in Aotearoa New Zealand, their interactions with other global change pressures, spatial analysis of Cyclone Gabrielle damage across ecosystems, and its impacts on braided rivers, wetlands, freshwater and coastal ecosystems, threatened species, and conservation infrastructure.

Environmental change in belowground ecosystems

Soils harbour diverse microbial and invertebrate communities that support crucial ecosystem functions like organic matter decomposition, soil structure maintenance, and biogeochemical cycling, therefore contributing to vital ecosystem services such as food production, water regulation, waste management, and carbon sequestration. The effects of anthropogenic environmental stressors on soil communities however, are still poorly understood, particularly in Aotearoa New Zealand ecosystems. This symposium aims to shed light on the impacts of environmental drivers and disturbance events on soil microbial and faunal communities. By highlighting recent advances in soil ecology within and beyond New Zealand, this symposium will present insights into how belowground impacts of environmental stressors such as environmental warming, fire, biological invasions, pathogen outbreaks, and habitat fragmentation can influence soil biodiversity and community structure, feedbacks between soil biota and native plant species, and  consequences of environmental changes for soil ecosystem functions. Additionally, we will explore how soil communities respond to restoration interventions, illuminating potential pathways for ecosystem recovery and resilience enhancement. Together, the research advances presented in this symposium will emphasize the interconnectedness of soil ecosystems and their importance for understanding and managing terrestrial ecosystems in the face of global environmental change. Join us to gain insights into the intricate relationships between environmental change, soil biota, and ecosystem functioning, with implications for sustainable land management and restoration efforts in Aotearoa New Zealand.

Indigenous forest restoration and protection, lessons from Aotearoa New Zealand’s long conservation movement to address emerging threats

Aotearoa New Zealand has a long and proud history of biodiversity conservation and kaitiakitanga. Traditionally, and continuing today, indigenous forest conservation has focused on the management of introduced mammalian pests and the translocation of threatened species. Significant conservation success stories have been underpinned by the actions of mobilised communities. However, our forests are now also threatened by incipient microbial plant pathogens, such as Phytophthora agathidicida (kauri dieback) and Austropuccinia psidii (myrtle rust), that present a new set of challenges. It is unlikely that these pathogens will be eradicated; there will not be a Pathogen Free 2050. Looking forward, we need to build on Aotearoa NZ's rich history of conservation and pest management, while shifting towards a holistic ecological approach aligned with Te Ao Māori approaches, to develop new knowledge, tools and technologies, and methods to address these threats.

In this symposium, we invite presentations from researchers and practitioners to consider what we can learn from other conservation challenges and what we must do differently. The symposium will close with an open discussion to identify the greatest challenges and opportunities.

 Topics of interest include:

  • Mobilising people
  • Te Ao Māori approaches and kaitiakitanga
  • Monitoring and managing spread of invasive species
  • Alternative management options, when eradication isn’t an option
  • Working in partnership and collaboration
  • Plant conservation and translocation
  • Population and community modelling approaches
  • Interactions with other disturbance agents and climate change

Harnessing ecological sciences to improve primary industry sustainability, productivity and resilience

The primary industries are a crucial component of New Zealand’s economy and cultural identity, providing rural jobs, supporting communities in the regions, and providing a backdrop to the lives of New Zealanders.  For example, in 2023 the primary industries (excluding mining) contributed 5% of New Zealand’s total GDP. Furthermore, agriculture, horticulture and plantation forestry occupy approximately 50% of New Zealand’s land mass (approximately 40, 8 and 2%, respectively) and land management decisions made by these industries strongly influence New Zealand’s environment. 

Agriculture, horticulture and forestry are reliant on New Zealand’s natural capital, and they face numerous rising challenges as a result of global change, including the impact of extreme events under climate change, biotic threats, and socio-economic changes including fluctuations in global markets and social license to operate.  On the other hand, there are also significant opportunities for improved ecological, social and financial sustainability through new technologies and new approaches to land management. Responding to these challenges and opportunities requires ecological thinking to develop systems that are resilient, productive, and sustainable, and that provide multiple co-benefits.  For example, it is important that decision makers in the primary industries understand how components interact within and between ecosystems to allow optimisation and reduce the risk of unintended consequences.

Given the importance of forestry to Rotorua’s economy and community, this session may have a greater focus on forestry, however there are shared challenges across the primary sector, and we will also include presentations from other primary industries.  

Topics of interest include:

  • Connections among the ecological, agricultural, horticultural and/or silvicultural sciences
  • Multi-benefit primary production systems
  • Alternative primary production systems such as Continuous Cover Forestry (CCF), mixed species plantations, and native species plantations.
  • Strategic integration of landuses, e,g. next generation silvopastoral systems and land sharing & sparing

Measuring and Managing Carbon in New Zealand’s Ecosystems

Healthy ecosystems sequester and store carbon. Maintaining and increasing these carbon stocks is essential for New Zealand’s ecosystems to thrive and for meeting our international climate obligations to reduce our net emissions. To do this, we need to understand drivers of carbon stock change and accurately measure those changes. The programmes ‘Maximising Forest Carbon’ lead by Te Uru Rākau New Zealand Forest Service and ‘Maximising Carbon in Native Ecosystems’ lead by the Department of Conservation are undertaking research into New Zealand’s ecosystem carbon stocks. This symposium will highlight research important to programme themes, including the use of remote sensing technologies to better measure New Zealand’s forest carbon stocks at large scales, understanding the impacts of introduced browsers on forest carbon, and forest and wetland restoration for carbon sequestration. The opportunity before us is to design management activities that simultaneously enhance carbon storage, improve climate resilience, and support biodiversity to thrive. Talks about capturing, managing, or measuring carbon – or anything else related to carbon in natural systems - are welcome.

Plant Ecology in a Changing Climate

Climate change is a global threat, with accelerating shifts in temperature, rainfall, major disturbances, and sea level rise. With high rates of endemic species, New Zealand, like other island systems, is at high risk of biodiversity losses as climate change contributes to other on-going threats such as habitat loss, invasive species, and pollution. As the foundation of terrestrial communities, the resilience and stability of plant populations is critical for conservation of New Zealand’s biodiversity under future climate change. In this symposium, we showcase new research investigating New Zealand plant ecology in a changing climate. We invite further speakers to represent gender balance, highlight Māori perspectives, and include early career scientists. Through these talks, current and future research directions will be highlighted for this emerging and critical research area, contributing to the conservation of New Zealand’s flora.

Ecology in an urban environment

As populations expand and cities grow, the importance of our urban environments only increases for preserving biodiversity, combating climate change, and making cities liveable. Currently over 90% of New Zealand’s population lives in urban areas. Urban ecosystems are the ones that people most frequently interact with, and in some cases may be the only exposure they have to ecology. The way we shape urban environments presents novel challenges and opportunities for life to overcome as species adapt to new stressors, nutrient loads, and communities. Successful urban designs help life find solitude in parks, reserves, and wetlands, but urban development has also led to unsavoury areas where weeds, pests, or diseases thrive. The close proximity of urban ecosystems to human populations also allows for unparalleled access to citizen science endeavours, and allows ecologists to better engage with local communities. 

This symposium aims to highlight the grime and the glory of life in our urban landscapes. Topics will include the challenges of preserving fragile habitats, and the way some plants and animals adapt to this highly disturbed environment. We encourage talks from all walks of ecology, environmental science, and social research that consider urban or peri-urban systems, both aquatic and terrestrial.
