Kernel density estimation of conditional distributions to detect responses in satellite tag data

open access: yesAnimal Biotelemetry, 2022
Background As levels of anthropogenic noise in the marine environment rise, it is crucial to quantify potential associated effects on marine mammals. Yet measuring responses is challenging because most species spend the majority of their time submerged ...

Changes in dive behaviour during naval sonar exposure in killer whales, long-finned pilot whales and sperm whales

open access: yesFrontiers in Physiology, 2012
Anthropogenic underwater sound in the environment might potentially affect the behavior of marine mammals enough to have an impact on their reproduction and survival.

How man-made interference might cause gas bubble emboli in deep diving whales

open access: yesFrontiers in Physiology, 2014
Recent cetacean mass strandings in close temporal and spatial association with sonar activity has raised the concern that anthropogenic sound may harm breath-hold diving marine mammals.

Decompression versus decomposition: distribution, quantity and gas composition of bubbles in stranded marine mammals

open access: yesFrontiers in Physiology, 2012
"Gas Bubble Disease" or Decompression-like Sickness" was described in stranded beaked whales linked to military sonar. Findings of gas bubble presence or associated lesions in marine mammals have been reported more and more often during ...

Facilitating macrosystem biology with organismal‐scale airborne remote sensing: Challenges and opportunities

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Emergent ecosystem properties, such as population and trait distributions, biodiversity and energy and water fluxes, occur because of the dynamic interactions of individuals in their environment.

The Effects of Noise on the Juvenile Life Stage of Crustaceans: Behavioral, Cellular, and Molecular Responses in Procambarus clarkii

open access: yesIntegrative Zoology, EarlyView.
Juvenile Procambarus clarkii exposed to noise exhibited behavioral changes, shifts in enzymatic activity, and altered expression of stress and immune genes. The findings highlight the sensitivity of invertebrate juveniles to anthropogenic acoustic pollution.

Declining abundance of beaked whales (family Ziphiidae) in the California Current large marine ecosystem.

open access: yesPLoS ONE, 2013
Beaked whales are among the most diverse yet least understood groups of marine mammals. A diverse set of mostly anthropogenic threats necessitates improvement in our ability to assess population status for this cryptic group.

Common ground: Efficient, consistent, observer‐independent bioacoustic call density estimation with adjudicated ground truth and capture–recapture detection functions

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Passive acoustic recording is a cost‐effective method for monitoring vocal animals. Within this field, there is an increasing focus on automated detection algorithms for counting calls and estimating call density (in space and time). For accurate interpretation of such results, it is important to understand and correct biases introduced by ...

Fish welfare in a changing world: New developments and current challenges

open access: yesJournal of Fish Biology, EarlyView.
Abstract The welfare of non‐human animals is central to ethical discussions on animal use, with increasing attention to fish welfare across research, aquaria, aquaculture, and fisheries. This paper reviews current theoretical approaches to animal welfare and recent advances in defining and assessing fish welfare since the seminal paper by Huntingford ...
