Abstract Globally, collapse of ecosystems—potentially irreversible change to ecosystem structure, composition and function—imperils biodiversity, human health well‐being. We examine the current state recent trajectories 19 ecosystems, spanning 58° latitude across 7.7 M km 2 , from Australia's coral reefs terrestrial Antarctica. Pressures global climate regional impacts, occurring as chronic ‘presses’ and/or acute ‘pulses’, drive collapse. Ecosystem responses 5–17 pressures were categorised...
Maximising survey efficiency can help reduce the tradeoff between spending limited conservation resources on identifying population changes and responding to those through management. Burrow‐nesting seabirds are particularly challenging because nests cannot be counted directly. We evaluated a stratified random design for generating unbiased estimates simultaneously four petrel species nesting Macquarie Island, Australia, where cue, burrow entrances, is similar all species. also compared use...
Abstract The eradication of invasive species from islands yields significant conservation returns. However, novel challenges continue to arise as projects expand in their scope, complexity and scale. Prey‐loss secondary poisoning were historically considered have limited impact on native top‐order predators when planning eradications, but this has rarely been tested quantitatively. We used a 10‐year timeseries Brown Skua Stercorarius antarcticus lonnbergi breeding surveys isotopic dietary...
Abstract The Vestfold Hills are a 400 km 2 , isolated ice-free oasis in eastern Antarctica featuring large areas with translucent quartz rocks that provide habitat for hypolithic microbial communities underneath. We used high-throughput DNA sequencing of 16S and 18S ribosomal RNA amplicons to characterize bacterial eukaryotic across the Hills. found high-level, local heterogeneity community structure consistent limited dispersal between hypoliths. Hypolithic were dominated by heterotrophic...
ABSTRACT Maximising survey efficiency can help reduce the trade-off between spending limited conservation resources on evaluating performance of past interventions and directing those towards future interventions. Seabird responses to island eradications are often poorly evaluated owing financial, logistical methodological challenges associated with remote field work species ecology. We surveyed an assemblage threatened seabirds following world’s largest eradication multiple invasive...
Abstract Sleeper populations of non-native species can remain at low abundance for decades before irrupting. For over a century, fallow deer ( Dama dama ) in the island state Tasmania, Australia, remained and close to region which they were released. Recently, there are indications population has increased distribution. Here, we spatially quantify change using time series annual spotlight counts from 1985 2019 (total 5,761 counts). Next, predict potential further range expansion, global...
