Tracking the global application of conservation translocation and social attraction to reverse seabird declines

Proceedings of the National Academy of Sciences, Journal Year: 2023, Volume and Issue: 120(16)

The global loss of biodiversity has inspired actions to restore nature across the planet. Translocation and social attraction deliberately move or lure a target species restoration site reintroduce augment populations enhance ecosystem resilience. Given limited conservation funding rapidly accelerating extinction trajectories, tracking progress these interventions can inform best practices advance management outcomes. Seabirds are globally threatened commonly targeted for translocation (“active seabird restoration”), yet no framework exists efforts nor informing practices.

Listening to animal behavior to understand changing ecosystems

Trends in Ecology & Evolution, Journal Year: 2024, Volume and Issue: 39(10), P. 961 - 973

Published: July 6, 2024

Interpreting sound gives powerful insight into the health of ecosystems. Beyond detecting presence wildlife, bioacoustic signals can reveal their behavior. However, behavioral information is underused because identifying function and context animals' sounds remains challenging. A growing acoustic toolbox allowing researchers to begin decoding by linking individual population-level sensing. Yet, studies integrating tools for across levels biological organization remain scarce. We aim catalyze emerging field bioacoustics synthesizing recent successes rising analytical, logistical, ethical challenges. Because behavior typically represents first response environmental change, we posit that will provide theoretical applied insights adaptations global change.

Anthropogenic impacts at the interface of animal spatial and social behaviour

Philosophical Transactions of the Royal Society B Biological Sciences, Journal Year: 2024, Volume and Issue: 379(1912)

Published: Sept. 4, 2024

Human disturbance is contributing to widespread, global changes in the distributions and densities of wild animals. These anthropogenic impacts on wildlife arise from multiple bottom-up top-down pathways, including habitat loss, resource provisioning, climate change, pollution, infrastructure development, hunting our direct presence. Animal behaviour an important mechanism linking these disturbances population outcomes, although behavioural pathways are often complex can remain obscured when different aspects studied isolation one another. The spatial–social interface provides a lens for understanding how animal’s spatial social environments interact determine its phenotype (i.e. measurable characteristics individual), phenotypes feed back reshape environments. Here, we review studies animal at understand predict human affects movement, distribution intraspecific interactions, with consequences conservation populations ecosystems. By mechanisms better design management interventions mitigate undesired disturbance. This article part theme issue ‘The interface: theoretical empirical integration’.

Home range and dynamic space use reveals age‐related differences in risk exposure for reintroduced parrots

Conservation Science and Practice, Journal Year: 2024, Volume and Issue: 6(5)

Published: April 12, 2024

Abstract Individual‐level differences in animal spatial behavior can lead to differential exposure risk. We assessed the risk‐exposure of a reintroduced population kākā ( Nestor meridionalis ) fenced reserve New Zealand by GPS tracking 10 individuals and comparing proportion each individual's home range beyond reserve's fence relation age, sex, fledging origin. To estimate dynamic space use, we used sweeping window framework occurrence distributions (ODs) from temporally overlapping snapshots. For OD, calculated outside assess temporal risk exposure, area, centroid, overlap represent behavioral pattern use. Home area declined significantly consistently with use juvenile was more dynamic, particularly locational changes The wider‐ranging younger resulted time spent reserve, which aligned higher number incidental mortality observations. Quantifying both is an effective approach provide guidance for management interventions. also emphasize approach, flexible insights into species' ecology.

Interspecies conflict, precarious reasoning, and the gull problem in the Gulf of Maine

Conservation Biology, Journal Year: 2024, Volume and Issue: 38(6)

Published: May 20, 2024

Abstract Contemporary conservation science requires mediating conflicts among nonhuman species, but the grounds for favoring one species over another can be unclear. We examined premises through which wildlife managers picked sides in an interspecies conflict: seabird Gulf of Maine (GOM). Managers GOM follow a simple narrative dubbed gull problem . This assumes Larus gulls are overpopulated and unnatural region. In turn, these assumptions make easy target culling lethal control when birds come into conflict with other seabirds, particularly Sterna terns. Surveying historical, natural ecological evidence, we found no scientific support claim that GOM. Claims overpopulation originated from historical context rising populations became nuisance to humans. Further, only limited evidence anthropogenic subsidies region, especially compared provided seabirds. The risks consequences leveraging precarious include cascading plans cull additional populations, obfuscation more fundamental environmental threats looming paradox conservation—even if is still inclined protect terns Our close look at regional history practice thus revealed importance not decisions, also decision‐making.

A multisensory approach to understanding bat responses to wind energy developments

Mammal Review, Journal Year: 2024, Volume and Issue: 54(3), P. 229 - 242

Abstract Millions of bats are killed at wind energy facilities worldwide, yet the behavioural mechanisms underlying why vulnerable to turbines remain unclear. Anthropogenic stimuli that alter perceptions environment, known as sensory pollution, could create ecological traps and cause bat mortality farms. We review abilities evaluate potential associated with farms examine role spatial scale on perceptual pollutants facilities. Audition, vision, somatosensation olfaction modalities use perceive their including turbine structures, but they will not all be useful same scales. Bats most likely vision landscape, obstruction lighting may first cue attract from kilometres away. Research assesses risks posed by specific pollutants, when conducted appropriate scale, can help identify solutions reduce mortality, such determining attractiveness a landscape scale.

Successful translocation of Newell’s Shearwaters and Hawaiian Petrels to create a new, predator free breeding colony

Frontiers in Conservation Science, Journal Year: 2023, Volume and Issue: 4

Newell’s Shearwater ( Puffinus auricularis newelli; NESH) and Hawaiian Petrel Pterodroma sandwichensis; HAPE) are listed under the U.S. Endangered Species Act have declined by 94% 78%, respectively, since 1993 due to habitat degradation, predation introduced predators, collisions with powerlines light attraction. Given challenges in protecting nesting birds their rugged montane habitats, it has long been desirable create populations of both species more accessible locations that offer a higher level protection. We translocated 110 HAPE 86 NESH chicks over six-year period from 2015-2020 2.5-ha predator-free enclosure on Kaua`i, Hawai`i. In addition invasive plant removal native out-planting, we installed 76 artificial burrows provide sites. Chicks were tube fed 1-20% body weight daily form slurry comprised squid, fish, salmon oil, Pedialyte. All 96% (N=106) survived fledging. Eight HAPE, including three breeding pairs, one returned as adults translocation site bred at site, resulting first colony this species.

Laysan ( Phoebastria immutabilis ) and Black-footed Albatrosses P. nigripes nest primarily on low-lying atolls in the Northwestern Hawaiian Islands that are threatened by inundation from sea level rise increasing storm surge associated with climate change. Restoration or creation of breeding colonies higher islands is among highest priority conservation actions for these species. A previous structured decision-making analysis identified California Channel as a possible restoration site Albatross. The Current part natural foraging ranges albatrosses.
