Enigmatic Nodal and Lefty gene repertoire discrepancy: Latent evolutionary history revealed by vertebrate‐wide phylogeny

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Homology in vertebrate body plans is traditionally ascribed to the high‐level conservation of regulatory components within the genetic programs governing them, particularly during the “phylotypic stage.” However, advancements in embryology and molecular phylogeny have unveiled the dynamic nature of gene repertoires responsible for early ...

The Sonar Model for Humpback Whale Song Revised

open access: yesFrontiers in Psychology, 2018
Why do humpback whales sing? This paper considers the hypothesis that humpback whales may use song for long range sonar. Given the vocal and social behavior of humpback whales, in several cases it is not apparent how they monitor the movements of distant

Application of Suction-cup-attached VHF Transmitters to the Study of Beluga, Delphinapterus leucas, Surfacing Behavior in Cook Inlet, Alaska [PDF]

open access: yes, 2000
Suction-cup-attached VHF radio transmittes were deployed on belugas, Delphinapterus leucas, in Cook Inlet, Alaska, in 1994 and 1995 to characterize the whales' surfacing behavior.

Using spatial capture–recapture methods to estimate long‐term spatiotemporal variation of a wide‐ranging marine species

open access: yesEcography, EarlyView.
Determining population status to inform mitigation of anthropogenic threats requires statistical approaches that investigate spatial and temporal variation. In the face of climate change it is increasingly important to differentiate between changes in population size and redistributions of populations.

Innovative Dual Rotor Wind Turbine Design Based on Humpback Whale Blades: Simulation Analysis

open access: yesEnergy Science &Engineering, EarlyView.
To enhance the performance of wind turbines, this study investigates the integration of two wind energy harvesting systems. An optimal wind turbine configuration has been identified by using dual rotor wind turbine technology with a novel blade design known as the humpback blade, which is inspired by the fins of humpback whales. ABSTRACT To enhance the

Capture and killing of small cetaceans in the Faroe Islands is inhumane and offers little scope for improvement

open access: yesFrontiers in Marine Science
The capture and killing of free-living small cetaceans in the Faroe Islands is described. After being driven on-shore by motor vessels, the animals are killed without pre-stunning using officially-prescribed methods that involve severing the spinal cord ...

Whaling and whale killing methods

open access: yesAnimal Welfare, 2013
Subsistence whale hunting dates back to 400AD (Perrinet al2009). Large-scale industrialised whaling to provide whale oil commenced in the late nineteenth century. Hunts escalated in the early 20th century and reports to the International Whaling Commission (IWC) show that over two million great whales were killed in hunts in the Southern Ocean between ...

Family history of ADHD associates with stronger problem‐solving skills amongst 2‐ to 3‐year‐olds

open access: yesJCPP Advances, EarlyView.
In this study 129 UK 2‐ and 3‐year‐olds, and 74 Swedish 3‐year‐olds, with and without a family history of ADHD and autism, completed a problem‐solving task. Our results show that children with ADHD traits and/or a family history of ADHD are likely to have an aptitude for generative problem‐solving when presented with highly motivating, ecologically ...
