PROGRESS TOWARDS UNDERSTANDING LANDSCAPE-LEVEL IMPACTS OF AQUATIC INVASIVE SPECIES

JAKE VANDER ZANDEN

Professor, Center for Limnology, University of Wisconsin-Madison

Invasive species are a major component of global environmental change. Aquatic systems are especially vulnerable to invasive species impacts. Much of our current understanding of aquatic invasive species impact is at the local or site level. In contrast, invasive species impacts are playing out across vast spatial scales on heterogeneous landscapes, and invasive species prevention and management efforts demands consideration of landscape-level impact. How can we ‘scale up’ an understanding of site-level impacts to the broader landscape scale? This talk will synthesize how aquatic invasive species distribution, site occupancy, abundance, and local impact ultimately determine landscape-level impact. Scaling up our understanding of invasive species impacts to the landscape level and recognizing spatial heterogeneity will help inform invasive species risk assessment, management, and prevention. While there remain many gaps in our understanding, current evidence suggests that the spatial distribution of aquatic invasive species impacts is right-skewed.

Embarking on the development of a community-driven, collaborative lake/catchment management plan for the Upper Clutha: An opportunity for Catchments otago members to engage

Marc Schallenberg, Chris Arbuckle (Aspiring Environmental), Don Robertson (Guardians of Lake Wanaka)

The maintenance of good environmental conditions in the Upper Clutha catchment is a priority for many people living in the region.  High population growth and development rates in the catchment are causing some concern about potential impacts on the environment.  Recent changes in environmental early warning indicators and the appearance of "lake snot" in Lake Wanaka have focused community concerns about development around the lake.  The community has also expressed concern that the health and condition of the Upper Clutha lakes is not being adequately monitored.  Consequently, local interest is building to develop a lake and catchment management plan that expresses and accounts for local environmental, social, cultural and economic values of the region, that summarises information about the ecological functioning of the lake/catchment system, and that proposes management actions to safeguard environmental values critical to the future of the region.  

This seminar will present where discussion are at with regard to the development of a lake/catchment management plan and will discuss how experts could become involved in helping the community develop the plan.

Agriculture and the Environment – NZ in 2016. Is it time for a “One World – One Health” approach

Alison Dewes

The Centre for Sustainability is pleased to host a seminar next month titled “Agriculture and the Environment – NZ in 2016” presented by Alison Dewes. A fourth generation dairy farmer and second generation veterinarian, Alison is a firm believer that our future food production systems have to be profitable and resilient while protecting and replenishing ecological health. She will discuss the need for a a paradigm shift from the current model to greater focus on wellbeing (one world: one health) where increasing production (output) and debt (stress) is replaced by increasing profit and wellbeing (resilience). 

Wednesday 11 May, 4-5pm; Centre for Sustainability Seminar Room, 563 Castle Street

 

Upcoming Seminar - Thursday 28 April

Use of freshwater planarians to evaluate toxic effects of pharmaceuticals and personal care products

Mei-Hui Li Environmental Ecology Lab / Environmental Toxicology Lab, Department of Geography, National Taiwan University.

Mei-Hui Li, a professor in the Department of Geography at National Taiwan University, is visiting our Department until 29 April. She is an environmental toxicologist by training, and most of her publications are in this area. Recently she changed her research focus from an organism level to the ecosystem level, and she is now especially interested in studying structure and function of freshwater ecosystems. If you'd like to have a chat with her before Thursday, please feel free to stop by in her office MG22 (Main Zoology Building, ground floor) or email her beforehand (meihuili@ntu.edu.tw) to arrange a time.

Thursday 28 April; 12-1pm; Marples seminar room, Main Zoology Building, 1st Floor, 340 Great King Street, Dunedin

 

Launch Day!

On Wednesday 13 April Catchments Otago was launched publicly. Catchments Otago aims to engage with Central Otago Lake communities to learn more about their aspirations, goals and concerns for the lakes and the surrounding catchments. Over the coming months, researchers from Catchments Otago will continue discussions with a range of community members to establish priorities for research from a community perspective and together develop research applications addressing these identified gaps. Catchments Otago has the philosophy that strong successful collaborations start with local community involvement from day one, and continue throughout research development, initiation and completion. Working together, it is anticipated equitable and sustainable land and water management approaches can be established, ensuring the future health of the Central Otago Lakes.
