Araceli Samaniego (Manaaki Whenua – Landcare Research, Auckland, New Zealand) and colleagues have published open access in the journal Wildlife Research on the possible role of alien slugs in the failure of the 2021 attempt to eradicate the albatross- and petrel-killing House Mice of Gough Island.

The paper’s abstract follows:

“Context: House mice (Mus musculus) are the main drivers of biodiversity declines on Gough Island (6500 ha; 40°21′S, 009°53′W), central South Atlantic. A mouse eradication operation was planned, the largest global attempt targeting only this species. Understanding and managing challenges of operating at such scales are crucial for maximising the chance of eradication success. The Gough Island mouse eradication attempt was implemented between June and August 2021, after years of planning and trials. We expected poor weather and negligible non-target bait consumption.

Aims: We aimed to assess the impact of expected and unexpected challenges faced during the eradication operation on Gough Island, namely poor weather and rapid bait disappearance.

Methods: We set up bait degradation plots across the primary habitats to monitor the impact of expected heavy rain on bait pellets. In contrast, bait availability monitoring and slug laboratory trials were set up ad hoc in response to unexpected observations of high bait consumption by invasive slugs in the lowlands, where both slugs and mice are more abundant.

Key results: Bait degradation rates were very different between the highlands and the lowlands, with bait in the highlands lasting about six times longer, despite bait pellets receiving more precipitation and the highlands being persistently under cloud. Bait availability in the lowlands dropped by >80% within a few days of the second and third bait application, down to critically low levels (∼2 kg ha⁻¹). Importantly, mouse activity was negligible by this time. Non-native slugs appeared to be the main cause of such a sudden drop in rodent bait availability.

Conclusions: The expected rainy weather was not a significant direct cause of bait degradation in the short term. In contrast, the unexpected slug interference, overlooked in earlier planning trials, resulted in major adjustments of the baiting strategy. Indeed, the rapid bait disappearance in the lowlands triggered the third bait application over this area, at a higher rate. This was not enough, as mice are still present.

Implications: This is the first report of slug interference during aerial rodent eradications. Our results illustrate how interference by non-target species could affect future pest eradications using baits and should, as far as possible, be assessed early during planning.”

Applications are still open for ACAP’s 2022 Secondment Programme. 

Applicants are advised to focus proposals on tasks contained within the work programmes of the Advisory Committee (Annex 4, MoP7 Report) and Secretariat (see Annex 2, MoP7 Report). Previous successful proposals have included:

• Habitat selection of the Black-browed Albatross (Thalassarche melanophris) in the South-West Atlantic: importance of marine fronts and fishing activity 
• Connecting knowledge, people and countries: Advancing in outreach, understanding of threats and mitigation measures for the conservation of Pink-footed Shearwater (Ardenna creatopus) throughout its cycle. 

Progress reports from previous and ongoing secondments (including the examples above) can be found in the Advisory Committee Information Papers from previous meetings, here. Proposals should aspire to foster cross-Party collaboration, knowledge-sharing and capacity-building within Parties. Applicants are encouraged to develop proposals that account for any ongoing practical challenges and limitations associated with the COVID-19 pandemic.

Applications will only be accepted from ACAP Parties.  Applicants are encouraged to contact the Working Group Convenors, the Advisory Committee Chair or Vice-chair, or the This email address is being protected from spambots.

Applications for the position of Director of the FitzPatrick Institute, at the level of Associate Professor or Professor are now requested.  “In addition to a proven record of internationally recognized scholarship and a demonstrated commitment to stimulate research and postgraduate studies, this position demands innovation, strategic foresight, and the ability to thrive within a dynamic African environment; as well as experience of managing teams of biologists and support personnel.”

Requirements for the job:

• A relevant PhD and proven record of internationally recognized scholarship and a demonstrated commitment to stimulate research and postgraduate studies;
• A strong track record of teaching at the undergraduate and postgraduate levels;
• A track record of attracting external funding;
• A track record of providing inspiring and unifying leadership and mentorship to diverse teams;
• A record of forging interdisciplinary and cross-institutional linkages; and
• Proven administrative and managerial skills, including the ability to formulate budgets and control expenditure.

Responsibilities:

• To maintain a research programme, involving postgraduate student training, in avian biology, particularly studies of living birds and their conservation.
• To provide educational and research leadership in modern approaches to avian biology and conservation.
• To contribute to teaching in the Department of Biological Sciences.
• To foster an inclusive and welcoming environment for students from a diversity of backgrounds.

The Albatross Task Force, an international team of scientific experts led by BirdLife International and the RSPB, has released its 2021/22 Annual Report on its work with fisheries to reduce seabird bycatch.

Albatross Task Force teams engage with fisheries in Argentina, Chile, Namibia and South Africa to encourage the uptake and proper implementation of ACAP’s Best Practice mitigation measures. More recently, in response to consumers increased interest in sustainable fishing, the Albatross Task Force have been utilising certification schemes such as that run by the Marine Stewardship Council, and direct engagement with retailers, to drive the adoption of mitigation measures by fisheries. 

On the release of the report, BirdLife International’s Bycatch Programme Manager, Rory Crawford stated, “…this has very much been the year the ATF went electronic, working on a number of projects to see how effective camera monitoring of our target fisheries might be in supporting seabird bycatch reductions – with some amazing results!

We’ve continued to build capacity to take action on preventing seabird bycatch in all parts of the fisheries management ecosystem – from crews to captains and fisheries observers to inspectors. Hundreds of key industry stakeholders have been empowered with seabird bycatch knowledge, and many teams have developed resources that institutions can use to deliver their own seabird bycatch training.

These are the vital foundations of making all theTaskForce’s efforts through the years sustainable – ensuring that keeping albatrosses off hooks and out of nets becomes a little part of everybody's job."
