The Dire Status of the Vaquita Has Worsened Analysis of the 2016 Acoustic Monitoring Program data has shown that almost half of the remaining vaquita population was lost between 2015…
Last call: Passive acoustic monitoring shows continued rapid decline of critically endangered vaquita
Thomas, Len; Jaramillo-Legorreta, Armando; Cardenas-Hinojosa, Gustavo; Nieto-Garcia, Edwyna; Rojas-Bracho, Lorenzo; Ver Hoef, Jay M.; Moore, Jeffrey; Taylor, Barbara; Barlow, Jay; Tregenza, Nicholas
The Journal of the Acoustical Society of America (2017)
The vaquita is a critically endangered species of porpoise. It produces echolocation clicks, making it a good candidate for passive acoustic monitoring. A systematic grid of sensors has been deployed…
Using environmental DNA to assess population-wide spatiotemporal reserve use
Stewart, Kathryn; Ma, Hongjuan; Zheng, Jinsong; Zhao, Jianfu
Conservation Biology (2017)
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…
Don’t forget the porpoise: Acoustic monitoring reveals fine scale temporal variation between bottlenose dolphin and harbour porpoise in Cardigan Bay SAC
Nuuttila, Hanna K.; Courtene-Jones, Winnie; Baulch, Sarah; Simon, Malene; Evans, Peter G. H.
Marine Biology (2017)
Populations of bottlenose dolphin and harbour porpoise inhabit Cardigan Bay, which was designated a Special Area of Conservation (SAC), with bottlenose dolphin listed as a primary feature for its conservation…
Causes of mortality of harbor porpoises Phocoena phocoena along the Atlantic and Pacific coasts of Canada
Fenton, H.; Daoust, P. Y.; Forzán, M. J.; Vanderstichel, R. V.; Ford, J. K. B.; Spaven, L.; Lair, S.; Raverty, S.
Diseases of Aquatic Organisms (2017)
There is increasing public interest in the overall health of the marine environment. Harbor porpoises Phocoena phocoena have a coastal distribution, and stranded animals function as sentinels for population and…
Marine noise budgets in practice
Merchant, Nathan D.; Faulkner, Rebecca C.; Martinez, Roi
Conservation Letters (2017)
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…
Diurnal variation in harbour porpoise detection – Potential implications for management
Williamson, L. D.; Brookes, K. L.; Scott, B. E.; Graham, I. M.; Thompson, P. M.
Marine Ecology Progress Series (2017)
Robust information on animal distributions and foraging behaviour is required to target management and conservation measures for protected species and populations. Visual survey data are commonly used to model these…
Dead useful; methods for quantifying baseline variability in stranding rates to improve the ecological value of the strandings record as a monitoring tool
ten Doeschate, Mariel T. I.; Brownlow, Andrew C.; Davison, Nicholas J.; Thompson, Paul M.
Journal of the Marine Biological Association of the United Kingdom (2017)
The ecological value of the stranding record is often challenged due to the complexity in quantifying the biases associated with multiple components of the stranding process. There are biological, physical…
Evaluating morphometric and metabolic markers of body condition in a small cetacean, the harbor porpoise (Phocoena phocoena)
Kershaw, Joanna L.; Sherrill, Meredith; Davison, Nicholas J.; Brownlow, Andrew; Hall, Ailsa J.
Ecology and Evolution (2017)
Mammalian body condition is an important individual fitness metric as it affects both survival and reproductive success. The ability to accurately measure condition has key implications for predicting individual and…
Genetic footprint of population fragmentation and contemporary collapse in a freshwater cetacean
Chen, Minmin; Fontaine, Michael C.; Ben Chehida, Yacine; Zheng, Jinsong; Labbé, Frédéric; Mei, Zhigang; Hao, Yujiang; Wang, Kexiong; Wu, Min; Zhao, Qingzhong; Wang, Ding
Scientific Reports (2017)
Understanding demographic trends and patterns of gene flow in an endangered species is crucial for devising conservation strategies. Here, we examined the extent of population structure and recent evolution of…
