This site-wide search returns results for all documents, events, metadata, and stories in Tethys, prioritizing the best matches. Partial word matches are returned (e.g. "environment" finds "environmental"), but every entered term must be found. If you don't find any results, try reducing the number of words entered or removing special characters. Filters to the right can help narrow your search. Tethys now features an integrated search with other marine renewable energy databases in PRIMRE - click the buttons below "Showing Results for" to search other integrated databases.

… Marine predator populations are crucial to the structure and functioning of ecosystems. Like many … and trends in abundance at land-based monitoring sites requires robust estimates of at-sea distribution, often on multi-region scales. Such an understanding is critical for effective … trends. Moreover, we provide SAC-specific estimates of at-sea distribution for use in marine spatial planning, demonstrating that hotspots of at-sea density in UK and Ireland-wide …

… interactions between tidal flow and topography drive the fine-scale porpoise spatio-temporal distribution at the site. Porpoise sightings were distributed non-uniformly within the survey … for porpoises at a local scale. Information on the functional mechanisms linking porpoise distribution to static and dynamic physical habitat variables is extremely valuable to the … and management of the species within the context of European conservation policies and marine renewable energy infrastructure development. … 2014-11-01 …

… The small-scale distribution of wide-ranging marine top predators has important implications for environmental … on Horns Reef, North Sea, that tidally driven upwelling is the most important factor governing distribution of harbour porpoises. For 3 principal reasons such a conclusion cannot be reached …

… 1. This study investigated the distribution of a population of bottlenose dolphins Tursiops truncatus resident in the Moray … this species. 2. Boat-based surveys and photo-identification techniques were used to study the distribution and movements of individually recognizable dolphins over a 3-year period. 3. … suggests that competition between individuals or social groupings may shape spatial distribution in this population. 7. Individuals exhibited rapid movements across the population's …

… Understanding the patterns of spatial and temporal distribution in threshold habitats of highly migratory and endangered species is important for … their habitat requirements and recovery trends. Herein, we present new data about the distribution of humpback whales ( Megaptera novaeangliae ) in neritic waters off the northern … for research. A total of 1048 whales distributed between 487 groups were sighted. The spatial distribution of humpbacks resembled the characteristic segregation of whale groups according to …

… Species Distribution Models (SDMs) are used regularly to develop management strategies, but many … methods ignore the spatial nature of data. To address this, we compared fine-scale spatial distribution predictions of harbour porpoise ( Phocoena phocoena ) using empirical … however, HBMs had twice the level of certainty, showed much finer-scale patterns in porpoise distribution, and identified some areas of high relative density that were not apparent in the …

For a previous Scottish Government funded project (MMSS/001/11), seal telemetry data were combined with haul-out specific population data to generate usage maps for both grey and harbour seals around the United Kingdom (UK) and Republic of Ireland (ROI) at a spatial resolution of 5 x 5 km (Jones et al., 2013). These maps provided estimates of seal abundance (and associated confidence intervals…
