Developmental 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 ...

Polar Record, 2016 This paper (1) reviews the history of sealing and whaling in the Southern Ocean to illustrate how market demands combined with no or ineffective regulation of catches led to the overexploitation and near extinction of southern fur seals, southern ...

Ecography, 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.

High pregnancy rates in humpback whales (Megaptera novaeangliae) around the Western Antarctic Peninsula, evidence of a rapidly growing population [PDF]
Royal Society Open Science, 2018 Antarctic humpback whales are recovering from near extirpation from commercial whaling. To understand the dynamics of this recovery and establish a baseline to monitor impacts of a rapidly changing environment, we investigated sex ratios and pregnancy ...

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

Whaling and whale killing methods
Animal 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 ...

Bloom compression alongside marine heatwaves contemporary with the Oregon upwelling season
Limnology and Oceanography, EarlyView.Abstract Marine heatwave (MHW) events have led to acute decreases in primary production and phytoplankton biomass in the surface ocean, particularly at the mid latitudes. In the Northeast Pacific, these anomalous events have occasionally encroached onto the Oregon shelf during the ecologically important summer upwelling season.
