Marine habitat heterogeneity underpins species distribution and can be generated through interactions between physical and biological drivers at multiple spatiotemporal scales. Passive acoustic monitoring (PAM) is used worldwide to study…
Many countries have made statutory commitments to ensure that underwater noise pollution is at levels which do not harm marine ecosystems. Nevertheless, coordinated action to manage cumulative noise levels is…
Scientists increasingly rely on protected areas to assist in biodiversity conservation, yet the efficacy of these areas are rarely systematically assessed, often as a byproduct of underfunding, particularly in developing…
The development of risk assessments for the exposure of protected populations to noise from coastal construction is constrained by uncertainty over the nature and extent of marine mammal responses to…
Offshore windfarms provide renewable energy, but activities during the construction phase can affect marine mammals. To understand how the construction of an offshore windfarm in the Maryland Wind Energy Area…
Analyses of animal species distribution in a neutral or minimally-interrupted habitat provide a baseline that is essential for assessment of population status, identification of key habitat, and conservation planning for…
Complex foldings of the vaginal wall are unique to some cetaceans and artiodactyls and are of unknown function(s). The patterns of vaginal length and cumulative vaginal fold length were assessed…
The effects of tagging on small cetaceans are difficult to assess due to logistical difficulties in recapturing the whales. In this study two narwhals, Monodon monoceros, and five harbor porpoises,…
Stomach content composition and prey-specific consumption rates of juvenile and adult harbor porpoises (Phocoena phocoena) were estimated from a data set including 339 stomachs collected over a 32 yr period…
Relatively little is known about the distribution and diversity of marine mammals around offshore anthropogenic structures. We present results obtained from incidental sightings of marine mammals around oil and gas…
