Ecological drivers of movement for two sympatric marine predators in the California current large marine ecosystem

Movement Ecology
Background An animal’s movement reflects behavioral decisions made to address ecological needs; specifically, that movement will become less directional in regions with high prey availability, indicating foraging behavior.

The Use of Unmanned Aerial Systems in Marine Mammal Research

Remote Sensing, 2017
Unmanned aerial systems (UAS), commonly referred to as drones, are finding applications in several ecological research areas since remotely piloted aircraft (RPA) technology has ceased to be a military prerogative.

Electrical Monitoring of Vibrio vulnificus–Host Cell Membrane Interactions in Simple and Complex Matrices

Advanced Materials Interfaces, EarlyView.
Supported lipid bilayers coupled with multielectrode array devices offer significant promise for pathogen–host cell membrane interaction studies. This work demonstrates, for the first time, the compatibility of this platform with biological fluids, in this case whole human blood, essential for any future point‐of‐care applications; as well as its ...

Abundance and distribution of ringed and bearded seals in the Chukchi Sea: a reference for future trends

Arctic Science
Ringed (Pusa hispida) and bearded (Erignathus barbatus) seals are vulnerable to decreasing sea ice habitat in the rapidly warming Arctic. In April and May 2016, we conducted an aerial survey over the ice-covered areas of the Chukchi Sea using thermal and

Health Assessments of Common Bottlenose Dolphins (Tursiops truncatus): Past, Present, and Potential Conservation Applications

Frontiers in Veterinary Science, 2019
The common bottlenose dolphin (Tursiops truncatus) is a global marine mammal species for which some populations, due to their coastal accessibility, have been monitored diligently by scientists for decades. Health assessment examinations have developed a

Competing tradeoffs between increasing marine mammal predation and fisheries harvest of Chinook salmon

Scientific Reports, 2017
Many marine mammal predators, particularly pinnipeds, have increased in abundance in recent decades, generating new challenges for balancing human uses with recovery goals via ecosystem-based management.

Role of the Setae in an Ectoparasitic Seal Louse in Reducing Surface Drag: Numerical Modeling Approach

Advanced Theory and Simulations, EarlyView.
The seal louse Echinophthirius horridus has uniquely shaped setae that may reduce drag during its host's dives. Using numerical simulations, this study demonstrates that their natural inclination promotes vortex formation, minimizing friction and energy loss. These findings provide insights into biological surface adaptations and may inspire the design
