Artificial intelligence (AI) is bringing ecological inference closer to decision-making, producing detections, alerts, trends, and prioritisation outputs. Yet, consensus on how to interpret or act on these remains limited - a new paper explores this opportunity doi.org/10.1111/1365...

This issue has emerged as another threat to the Arawa lakes with PFAs being found in Lake Rotorua. The close proximity of the airport to the lake has resulted in forever chemicals being detected - raising concerns about mahinga kai sourced from the lake.

With this focus on outcome-oriented research, we can no longer pitch projects simply because they are "interesting" 💩 The message is adopt the Spice Girls mindset: listen to what the funder "really, really wants", and explicitly state what concrete value the project will give back to society 🌏

From this viewpoint, one can consider how to better prepare a pitch for mission-based science funding. This message resonates since New Zealand (and other parts of the world) are pivoting towards mission-oriented research and innovation policies (or MOIPs for short).

4. "Now don’t go wasting my precious time" Lesson: Respect the reader's time. Wannabe is a tight pop song, lasting under three minutes. Proposal writers should show respect for an investor's time by getting straight to the point and capture the core value on the first page.

3. "If you really bug me then I’ll say goodbye" Lesson: Don't test the investor's patience. Proposals often fail when writers skip over crucial points requested by the funder, frustrating the reader. Focus on the need to know.

2. "If you wanna be my lover / You have got to give" Lesson: Deliver concrete value. Instead of just "taking" (asking for money to fund a project), a proposal needs to clearly demonstrate the reciprocal value and specific outcomes it will give back to the investor.

1. "Yo, I’ll tell you what I want... So, tell me what you want" Lesson: Understand your audience’s desired outcome. The Spice Girls had a target audience, and proposal writers must look beyond what benefits them and instead align with the investor's explicit strategic goals and funding priorities.

Trophic transfer efficiencies decrease with warming in freshwater ecosystems. Tradeoffs between primary production and TTEs may help explain why freshwater ecosystems with differing levels of production sustain similar food chain lengths (although some will benefit from trophic subsidies) #foodwebs

One of the famous stories in Te Arawa history is that of the rangatira Hatupatu, when he attempted to introduce tāmure (snapper) to the Arawa Lakes. The story holds that it was unsuccesful, despite the great effort made to bring live fish inland from the coast. Imagine if snapper were in the lakes🎣😉

What does this mean for management? Restoring kōura populations will require: - Targeted catfish control - Habitat enhancement to support recovery - Continued long-term monitoring to guide adaptive management

Frank Burdon @fburdon.bsky.social · 10/06/2026
Beyond the ecological impacts, the findings have serious cultural implications. In Lake Rotoiti, the decline of kōura has reached a point where customary Māori fisheries are no longer viable.

Frank Burdon @fburdon.bsky.social · 10/06/2026
Importantly, environmental conditions (water quality, dissolved oxygen, macrophyte cover) remained relatively stable—pointing to catfish predation as the key driver, rather than broader ecosystem degradation.

Drawing on nearly two decades of monitoring data (2005–2024), a clear pattern emerged: 📉 Significant declines in kōura abundance and biomass in invaded lakes 📊 No comparable changes in control lakes over the same period 🐟 Increasing catfish populations correlating with kōura collapse

Invasive species are widely recognised as a major threat to biodiversity—yet quantifying their true impact can be challenging without long-term data. Our recent research highlights just how significant these effects can be.
