Historic Wetland Degradation Causes Cryptic, Growth-Mediated Declines in Upstream Predatory Fish Through Collapse of Diadromous Prey Fishes

Presentation Abstract

New Zealand’s longfin eels (Anguilla dieffenbachii) are endangered, and conservation action is needed. One aspect of their biology that has traditionally been considered a major limitation to their population recovery, slow growth rate, could in fact present an opportunity for innovative new conservation strategies – enhancing their grow rates through improving high quality food supply. Here we present evidence showing that, when the diadromous fish īnanga (Galaxias maculatus) are abundant, they are an important food source for longfin eels and boost production. We use a range of proxies to show that, through trophic interactions, īnanga are able to propagate trophic resources from lowland wetlands throughout the catchment to the benefit of apex predators, longfin eels. This is showing by quantifying the landscape-scale benefit of intact wetlands, the implication of historic wetland loss and, finally, the benefit of contemporary wetland restoration.

Costa Rica’s Conservation Incentives

Presentation Abstract

Costa Rica’s experience shows how financial incentives can support voluntary conservation. This discussion examines Payments for Environmental Services (PES), Forest Emission Reduction Contracts (CREF), and National Forestry Financing Fund programs that conserve forests and protect water resources. It also considers how PES is being extended to marine and coastal ecosystems, including mangroves, broadening the focus to wetland conservation. Finally, it highlights how international cooperation and government support help recognize the benefits that ecosystems provide and encourage landowners across the country to participate in conservation efforts.

The Future of Lake Ice in a Warming World

Presentation Abstract

Lake ice is disappearing as the planet warms, but the changes extend beyond shorter winters. The remaining ice is thinning and weakening, threatening the safety and livelihoods of communities that depend on frozen lakes. Yet the planetary-scale effects of smaller lakes on ice phenology and overall lake-ice quality under climate change remain poorly understood. In this presentation, I will share findings from my research on ice phenology, thickness, and quality across 1.12 million Northern Hemisphere lakes. Our projections reveal widespread reductions in ice cover and thickness, along with a rising share of weaker white ice, with important consequences for ice stability and load-bearing capacity. I will also discuss how human activities and landscape modifications influence lake ice at different scales, and how alternative socioeconomic development pathways, ranging from sustainable to fossil-fuel-intensive futures, could shape the magnitude of future ice losses. Understanding these changes and how our societal choices drive them is essential to protecting frozen lakes and the communities that depend on them.

The “Amplifying Voices” series began in 2021 with the aim to promote the exciting work of early-career aquatic scientists from underrepresented groups in our global community. We hope you will join us in supporting the exciting work of our early career aquatic scientists!
