Ontogenetic and among-individual variation in foraging strategies of northeast Pacific white sharks based on stable isotope analysis. [PDF]
PLoS ONE, 2012 There is growing evidence for individuality in dietary preferences and foraging behaviors within populations of various species. This is especially important for apex predators, since they can potentially have wide dietary niches and a large impact on ...

Limnology and Oceanography: Methods, EarlyView.Abstract The difficulty of sampling zooplankton communities in situ has driven advancements in autonomous, remote sensing technology. The goal of this paper was to perform a gear comparison study testing the performance of one such piece of technology—a glider‐mounted four‐frequency echosounder—against traditional shipboard methods of measuring ...

Reconstructing Early Human Subsistence in Near Oceania: New Insights From Matenkupkum and Matenbek
International Journal of Osteoarchaeology, EarlyView.ABSTRACT The colonization of New Ireland ~44–40,000 years ago represents the earliest evidence of human occupation in Near Oceania. Yet, the precise impacts of climatic changes on subsistence strategies during the Late Pleistocene, Last Glacial Maximum, and Holocene remain poorly understood.

Olfaction Contributes to Pelagic Navigation in a Coastal Shark. [PDF]
, 2016 How animals navigate the constantly moving and visually uniform pelagic realm, often along straight paths between distant sites, is an enduring mystery. The mechanisms enabling pelagic navigation in cartilaginous fishes are particularly understudied.

Remote Sensing in Ecology and Conservation, EarlyView.Targeted conservation measures are contingent on robust knowledge of spatio‐temporal animal distribution in areas of interest. We explore unmanned aerial vehicle (UAV) transect monitoring as a novel method for standardized digital aerial surveys of marine megafauna by investigating the fine‐resolution spatio‐temporal distribution of harbour porpoises ...

The last frontier: catch records of white sharks (Carcharodon carcharias) in the Northwest Pacific Ocean. [PDF]
PLoS ONE, 2014 White sharks are highly migratory apex predators, globally distributed in temperate, sub-tropical, and tropical waters. Knowledge of white shark biology and ecology has increased recently based on research at known aggregation sites in the Indian ...
