Increases in invertebrate abundance and shifts in assemblage composition following rodent eradication on Lord Howe Island

Terence W. O’Dwyer, Maxim W.D. Adams, Thomas E. White, John Porter et autres

Abstract Invasive rodents represent one of the most serious threats to island ecosystems, affecting a wide range of native plants, vertebrates and invertebrates. While nearly ubiquitous on human-modified islands, the last four decades have seen the advent of targeted rodent eradications, which …

Increases in invertebrate abundance and shifts in assemblage composition following Rodent Eradication on Lord Howe Island

Terence W. O’Dwyer, Maxim W.D. Adams, Thomas E. White, Dean Portelli et autres

Abstract Invasive species are one of the major threatening processes impacting biodiversity on islands. In particular, introduced rodents represent one of the most serious threats to island ecosystems, affecting a wide range of native plants, vertebrates and invertebrates. While nearly ubiquitous on …

Global Marine Flyways Identified for Long‐Distance Migrating Seabirds From Tracking Data

Joanne M. Morten, Ana P. B. Carneiro, Martin Beal, Anne‐Sophie Bonnet‐Lebrun et autres

ABSTRACT Aim To identify the broad‐scale oceanic migration routes (‘marine flyways’) used by multiple pelagic, long‐distance migratory seabirds based on a global compilation of tracking data. Location Global. Time Period 1989–2023. Major Taxa Studied Seabirds (Families: Phaethontidae, Hydrobatidae, Diomedeidae, Procellariidae, Laridae and …

Large‐scale and long‐term wildlife research and monitoring using camera traps: a continental synthesis

Tom Bruce, Zachary Amir, Benjamin L. Allen, Brendan F. Alting et autres

Camera traps are widely used in wildlife research and monitoring, so it is imperative to understand their strengths, limitations, and potential for increasing impact. We investigated a decade of use of wildlife cameras (2012-2022) with a case study on Australian terrestrial vertebrates …

Have Rodents Impacted the Breeding and Distribution of Black Noddy Anous minutus on Lord Howe Island?

Nicholas Carlile, Lisa O’Neill, Terence W. O’Dwyer

Rodents are well known to impact nesting seabirds. However, not all seabird species are equally susceptible to rodents due to variations in size, nest-site selection, or nesting behaviour. The Black Noddy Anous minutus, a common tropical, tree-nesting species, began colonisation of North …

EXPRESSION OF CONCERN: A novel technique for estimating age and demography of long‐lived seabirds (genus Pterodroma ) using an epigenetic clock for Gould's petrel ( Pterodroma leucoptera )

Lauren Roman, Benjamin Mayne, C. Anderson, Yuna Kim et autres

Understanding the demography of wildlife populations is a key component for ecological research, and where necessary, supporting the conservation and management of long-lived animals. However, many animals lack phenological changes with which to determine individual age; therefore, gathering this fundamental information presents …

Protection and mortality of non-target terrestrial bird species during the eradication of rodents on Lord Howe Island

Terence W. O’Dwyer, Nicholas Carlile, Laura P. O’Neill, Horace L. Fairlamb et autres

Abstract To eliminate the destructive impact of rodents on islands, conservation practitioners commonly use rodenticides to eradicate these pests. Frequently used rodenticides, such as brodifacoum, are non-specific. Consequently, non-target species may be susceptible to the poison. While mitigation actions to protect against …

Conservation of the surface-nesting Kermadec Petrel Pterodroma neglecta neglecta in the South Pacific: clarifying breeding ecology and the threat of avian ground predators

Nicholas Carlile, Terence W. O’Dwyer

Summary Understanding population dynamics and impacts on island ecology remain top priorities for the conservation management of seabirds, particularly when attempting species-recovery for island restoration. Identifying suitable nesting habitat is a keystone detail in seabird restoration which can be complicated when predator …

At-Sea Movements of the White Tern Gygis alba in Waters Off Eastern Australia

Nicholas Carlile, Terence W. O’Dwyer

We present the first tracked movements of the medium-sized tropical White Tern Gygis alba, using Global Location Sensors (GLS), from a breeding colony on Lord Howe Island, South Pacific, Australia. The tracking period encompassed pre-breeding in 2018 to potential chick provisioning in …

Changing fortunes of the Black-winged Petrel Pterodroma nigripennis following the Lord Howe Island Rodent Eradication Project - interactions with other recovering species

Terence W. O’Dwyer, Nicholas Carlile, Lisa O’Neill, Luke R. Halpin

Summary In 2019, a Rodent Eradication Project (REP) was implemented on World Heritage listed Lord Howe Island, Australia. Among the species expected to benefit was a burrow-nesting seabird, the Black-winged Petrel Pterodroma nigripennis. Prior to the REP, we assessed causes of Black-winged …
