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…
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…
Habitat-based density models for three cetacean species off southern California illustrate pronounced seasonal differences
Becker, Elizabeth A.; Forney, Karin A.; Thayre, Bruce J.; Debich, Amanda J.; Campbell, Gregory S.; Whitaker, Katherine; Douglas, Annie B.; Gilles, Anita; Hoopes, Ryan; Hildebrand, John A.
Frontiers in Marine Science (2017)
Managing marine species effectively requires spatially and temporally explicit knowledge of their density and distribution. Habitat-based density models, a type of species distribution model (SDM) that uses habitat covariates to…
Year-round spatiotemporal distribution of harbour porpoises within and around the Maryland wind energy area
Wingfield, Jessica E.; O’Brien, Michael; Lyubchich, Vyacheslav; Roberts, Jason J.; Halpin, Patrick N.; Rice, Aaron N.; Bailey, Helen
PLOS ONE (2017)
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…
Harbour porpoise distribution can vary at small spatiotemporal scales in energetic habitats
Benjamins, Steven; van Geel, Nienke; Hastie, Gordon; Elliott, Jim; Wilson, Ben
Deep Sea Research Part II: Topical Studies in Oceanography (2017)
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…
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…
Distribution of three sympatric cetacean species off the coast of the central-western Gulf of Thailand
Jutapruet, Suwat; Intongcome, Atichat; Wang, Xianyan; Kittiwattanawong, Kongkiat; Huang, Shiang-Lin
Aquatic Mammals (2017)
Baseline data on the distribution patterns of animals disclose the dynamic function of habitat use as it relates to the accessibility of prey, social interactions, predator-prey interactions, and inter-habitat-patch mobility.…
Where is the risk? Integrating a spatial distribution model and a risk assessment to identify areas of cetacean interaction with fisheries in the northeast Atlantic
Breen, Patricia; Brown, Susie; Reid, David; Rogan, Emer
Ocean & Coastal Management (2017)
Throughout their range, marine mammals are vulnerable to incidental capture in fishing gear. Bycatch is a particularly important issue for cetaceans, which generally have lower potential rates of population growth…
Distribution of Dall’s porpoise, Phocoenoides dalli, in the North Pacific and Bering Sea, based on T/S Oshoro Maru 2012 summer cruise data
Suzuki, Sachiko; Sekiguchi, Keiko; Mitani, Yoko; Onishi, Hiroji; Kamito, Takehiko
Zoological Science (2016)
Dall's porpoise (Phocoenoides dalli) is a small toothed cetacean, widely inhabiting the North Pacific Ocean and adjacent seas, between about 30 and 62°N; however, only limited studies of its ecology…
Polybrominated diphenyl ethers (PBDEs) and their hydroxylated and methoxylated analogues in the blood of harbor, Dall’s and finless porpoises from the Japanese coastal waters
Ochiai, Mari; Nomiyama, Kei; Isobe, Tomohiko; Yamada, Tadasu K.; Tajima, Yuko; Matsuda, Ayaka; Shiozaki, Akira; Matsuishi, Takashi; Amano, Masao; Iwata, Hisato; Tanabe, Shinsuke
Marine Environmental Research (2016)
This study investigated the accumulation of polybrominated diphenyl ethers (PBDEs) and their hydroxylated and methoxylated analogues (OH-PBDEs and MeO-PBDEs) in the blood of harbor porpoises, Dall's porpoises, and finless porpoises…
