Application of DNA Methylation–Based Age Estimation to Construct an Age Structure of Humpback Whales in a Newly Emerged Wintering Ground Around Hachijojima Island, Tokyo Metropolis, Japan

Ecology and Evolution
Using a noninvasive DNA methylation (DNAm)–based age estimation method, we investigate the age structure of humpback whales that newly emerged around Hachijojima Island, Tokyo Metropolis, Japan to uncover the role of this area for this species.

Cetacean Stranding Response Program and Spatial–Temporal Analysis in Taiwan, 1994–2018

Animals
A national cetacean stranding response program in Taiwan has evolved significantly in the past three decades. Initially co-ordinated by National Taiwan University from 1994, the program transitioned to the Taiwan Cetacean Society in 1999, and local ...

A remotely operated blood sampling and sedative administration device in freely moving pinnipeds

Methods in Ecology and Evolution, EarlyView.
Abstract A remotely operated device for use with freely moving pinnipeds was designed and successfully developed for the collection of blood samples and the administration of sedatives via an indwelling, venous catheter. The performance of the sampler, called the ‘Mossquito’, was demonstrated on six wild caught, young‐of‐the‐year grey seals ...

Stranding survey as a framework to investigate rare cetacean records of the north and north-eastern Brazilian coasts

ZooKeys, 2017
Marine mammal stranding events are used as an important tool for understanding cetacean biology worldwide. Nonetheless, there are vast gaps of knowledge to be filled in for a wide range of species. Reputable information is required regarding species from

Acoustic indices are not useful for biodiversity research

Methods in Ecology and Evolution, EarlyView.
Abstract Biodiversity assessment using passive acoustic monitoring has historically been challenging due to the limited availability of multi‐species acoustic detectors. In this context, acoustic indices were introduced as an alternative way to represent species diversity in acoustic datasets.

Estimates of Marine Mammal, Sea Turtle, and Seabird Mortality in the California Drift Gillnet Fishery for Swordfish and Thresher Shark, 1996–2002 [PDF]

, 2004
Estimates of incidental marine mammal, sea turtle, and seabird mortality in the California drift gillnet fishery for broadbill swordfish, Xiphias gladius, and common thresher shark, Alopias vulpinus, are summarized for the 7-year period, 1996 to 2002 ...

Ecoacoustics for context‐rich direct and indirect trophic interaction data and ecological network construction

Methods in Ecology and Evolution, EarlyView.
Abstract Understanding species interactions is critical for ecology and conservation, yet conventional network construction methods often lack spatiotemporal resolution and important contextual information. The growing field of ecoacoustics enables remote sensing across large spatiotemporal scales and the monitoring of otherwise cryptic communities ...

Stranded cetaceans

Animal Welfare, 1994
The RSPCA (Royal Society for the Prevention of Cruelty to Animals) has produced a second edition of its stranded whales booklet. The first version was published out of the RSPCA's 1983 Stranded Whale Workshop and this 1994 edition incorporates additional information from a follow-up seminar run by the Society in November 1992.

COPIS: A robust and versatile robotic imaging system for the 3D digitization of natural history specimens with photogrammetry

Methods in Ecology and Evolution, EarlyView.
Abstract Ecologists and evolutionary biologists are increasingly turning to 3D models to use in scientific research. Natural history museums are one of the primary sources for specimens used as 3D models, and efforts are underway to digitize their collections using methods like photogrammetry.
