Enhancing AIS to Improve Whale-Ship Collision Avoidance and Maritime Security [PDF]

open access: yes, 2009
Whale-ship strikes are of growing worldwide concern due to the steady growth of commercial shipping. Improving the current situation involves the creation of a communication capability allowing whale position information to be estimated and exchanged ...

Postreproductive killer whale grandmothers improve the survival of their grandoffspring

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2019
Significance Why humans and some species of whales go through menopause remains an evolutionary puzzle. In humans, postreproductive females gain genetic benefits by helping family members—particularly increasing their number of surviving grandoffspring ...

Trends in marine species distribution models: a review of methodological advances and future challenges

open access: yesEcography, EarlyView.
Correlative species distribution models (SDMs) are quantitative tools in biogeography and macroecology. Building upon the ecological niche concept, they correlate environmental covariates to species presence to model habitat suitability and predict species distributions.

Using citizen science to better understand Risso’s dolphin (Grampus griseus) presence in northeast Scotland and the Northern Isles

open access: yesFrontiers in Conservation Science
There is no current population estimate for Risso’s dolphin (Grampus griseus) in Scottish waters and their distribution in the northeast of Scotland and the Northern Isles is poorly documented.

Twenty years of dynamic occupancy models: a review of applications and look to the future

open access: yesEcography, EarlyView.
Since their introduction over 20 years ago, dynamic occupancy models (DOMs) have become a powerful and flexible framework for estimating species occupancy across space and time while accounting for imperfect detection. As their popularity has increased and extensions have further expanded their capabilities, DOMs have been applied to increasingly ...

Gray Whale (Eschrictius robustus) Call Types Recorded During Migration off the West Coast of Vancouver Island

open access: yesFrontiers in Marine Science, 2018
Gray whale (Eschrichtius robustus) vocalizing behavior varies over its range, both in call type and frequency. This study adds to the growing body of passive acoustic research outside of the calving/breeding lagoons, and moves toward a description of ...
