Potential Impacts of Petroleum and Mineral Exploration and Production on Hector’s and Māui Dolphins (PDF)
The North Island population of Hector’s dolphins (Cephalorhynchus hectori) is formally described as a subspecies, the Māui dolphin (Cephalorhynchus hectori maui). Both Hector’s and Māui dolphins, are endemic to New Zealand waters, where animals are exposed to a range of human (anthropogenic) and non-human-induced threats. To better protect these species, the Department of Conservation (DOC) […]
Predictable changes in fish school characteristics due to a tidal turbine support structure (PDF)
There is uncertainty on the ecological effects of tidal stream turbines. Concerns include animal collision with turbine blades, disruption of migratory and foraging behaviour, attraction of animals to prey aggregating around turbines, or conversely displacement of animals from preferred habitat. This study used concurrent ecological and physical measurements to show the predictability of fish school […]
Habitat usage of Daubenton’s bat (Myotis daubentonii), common pipistrelle (Pipistrellus pipistrellus), and soprano pipistrelle (Pipistrellus pygmaeus) in a North Wales upland river catchment (PDF)
Distributions of Daubenton’s bat (Myotis daubentonii), common pipistrelle, (Pipistrellus pipistrellus), and soprano pipistrelle (Pipistrellus pygmaeus) were investigated along and altitudinal gradient of the Lledr River, Conwy, North Wales, and presence assessed in relation to the water surface condition, presence/absence of bank-side trees, and elevation. Ultrasound recordings of bats made on timed transects in summer 1999 […]
Potential audibility of three Acoustic Harassment Devices (AHDs) to marine mammals in Scotland, UK
The modelled acoustic characteristics of three Acoustic Harassment Devices (AHDs) deployed from a fully operational salmonid fish farm, located in the Sound of Mull, Scotland (UK) are presented, using empirical seabed and water column measurements at the same location. In the Beaufort Sea state 0, the depth range of 10–50 m is the maximum range […]
