Divergent post-breeding spatial habitat use of Laysan and black-footed albatross. Frontiers in Ecology and Evolution. https://doi.org/10.3389/fevo.2022.1028317 Understanding the at-sea movements of wide-ranging seabird species throughout their annual cycle is […]
Effect of a new offshore gas platform on harbor porpoise in the Dogger Bank
Offshore Oil and Gas (O&G) exploration and production has been cycling from cradle to grave for over 100 years, spanning many generations of marine fauna. Despite global occurrence of offshore infrastructure, implications of their presence for apex predators, including cetaceans, is under-studied. We analyzed data from autonomous underwater passive-echolocation-click detectors (C-PODs) deployed at an offshore […]
Effects of pile driving sound playbacks and cadmium co-exposure on the early life stage development of the Norway lobster, Nephrops norvegicus
Marine Pollution Bulletin, 179, 113667 (2022)DOI: https://doi.org/10.1016/j.marpolbul.2022.113667 There is an urgent need to understand how organisms respond to multiple, potentially interacting drivers in today’s world. The effects of the pollutants anthropogenic sound (pile driving sound playbacks) and waterborne cadmium were investigated across multiple levels of biology in larval and juvenile Norway lobster, Nephrops norvegicus under controlled […]
Comparing distribution of harbour porpoise using generalized additive models and hierarchical Bayesian models with integrated nested Laplace approximation
Ecological Modelling, 470, 110011, (2022)DOI: https://doi.org/10.1016/j.ecolmodel.2022.110011 Species Distribution Models (SDMs) are used regularly to develop management strategies, but many modelling methods ignore the spatial nature of data. To address this, we compared fine-scale spatial distribution predictions of harbour porpoise (Phocoena phocoena) using empirical aerial-video-survey data collected along the east coast of Scotland in August and September […]
Influence of offshore oil and gas structures on seascape ecological connectivity
Offshore platforms, subsea pipelines, wells and related fixed structures supporting the oil and gas (O&G) industry are prevalent in oceans across the globe, with many approaching the end of their operational life and requiring decommissioning. Although structures can possess high ecological diversity and productivity, information on how they interact with broader ecological processes remains unclear. […]
Cetacean distribution in relation to oceanographic features at the Kerguelen Plateau
The Kerguelen Plateau in the south-eastern Indian Ocean is one of the most isolated and understudied regions on earth. As part of the Kerguelen Plateau Drifts project, Marine Mammal Observer (MMO) data were collected during a seismic survey in the austral summer (January–February 2020). Relationships between observation effort, cetacean sightings, seismic operations, and oceanographic variables […]
Spatio-temporal variation in harbour porpoise distribution and foraging across a landscape of fear (PDF)
Understanding spatiotemporally varying animal distributions can inform ecological understanding of species’ behavior (e.g., foraging and predator/prey interactions) and support development of management and conservation measures. Data from an array of echolocation-click detectors (C-PODs) were analyzed using Bayesian spatiotemporal modeling to investigate spatial and temporal variation in occurrence and foraging activity of harbor porpoises (Phocoena phocoena) […]
