Individual animals are often given names by humans. For example, names are attributed to domestic animals to acknowledge their closeness to people, some research studies use names to identify differences between individuals in a study group, or zoos often use names to tell stories that attract public or media attention. Publicly naming individual a...

Widely available ‘fish‐finder’ echo‐sounding devices are beginning to be used in bathymetric studies to estimate geomorphic change. To date, however, there have been no applications in shallow and complex wetlands, where changes in sediment storage are notoriously dynamic in time and difficult to describe accurately in space. Therefore, in this stu...

Distribution maps of cetaceans and seabirds at basin and monthly scales are needed for conservation and marine management. These are usually created from standardized and systematic aerial and vessel surveys, with recorded animal densities interpolated across study areas. However, distribution maps at basin and monthly scales have previously not be...

Atlantic Puffins Fratercula arctica were counted at all known colonies in Orkney (excluding Sule Skerry) during the 2016 breeding season. Counts of individuals (IND) were made during pre-laying and incubation at all 20 sites and at six sites where burrows where physically accessible. In 2016 the Atlantic Puffin population of Orkney was estimated to...

Robust estimates of the density or abundance of cetaceans are required to support a wide range of ecological studies and inform management decisions. Considerable effort has been put into the development of line‐transect sampling techniques to obtain estimates of absolute density from aerial‐ and boat‐based visual surveys. Surveys of cetaceans usin...

Growing concerns about climate change and energy security have fueled a rapid increase in the development of marine renewable energy installations (MREIs). The potential ecological consequences of increased use of these devices emphasizes the need for high quality environmental impact assessment (EIA). We demonstrate that these processes are hamper...

We present a Geographic Information System (GIS) tool, SeaMaST (Seabird Mapping and Sensitivity Tool), to provide evidence on the use of sea areas by seabirds and inshore waterbirds in English territorial waters, mapping their relative sensitivity to offshore wind farms. SeaMaST is a freely available evidence source for use by all connected to the...

Assessments of the impact of offshore energy developments are constrained because it is not known whether fine-scale behavioural responses to noise lead to broader-scale displacement of protected small cetaceans. We used passive acoustic monitoring and digital aerial surveys to study changes in the occurrence of harbour porpoises across a 2000 km(2...

Offshore wind farms around the coasts of the British Isles have the potential to provide significant amounts of energy, and in addition to installed wind farms, there are large areas earmarked for further development, extending into deeper waters farther from the coast. However, these developments have the potential to impact on birds, in particula...
