The Largest Narwhal Tusk

Fractal analysis of narwhal space use patterns.

Quantifying animal movement in response to a spatially and temporally heterogeneous environment is critical to understanding the structural and functional landscape influences on population viability. Generalities of landscape structure can easily be extended to the marine environment, as marine predators inhabit a patchy, dynamic system, which influences animal choice and behavior. An innovati...

Arctic sea ice trends and narwhal vulnerability

Conservation measures related to global climate change require that species vulnerability be incorporated into population risk models, especially for those that are highly susceptible to rapid or extreme changes due to specialized adaptation. In the case of Arctic cetaceans, effects of climate change on habitat and prey availability have been subject to intense speculation. Climate perturbation...

Seasonal narwhal habitat associations in the high Arctic

Movements and behavior of top marine predators are often closely linked with productive oceanic fronts or regional prey aggregations. Consequently, it is of interest to quantify habitat needs and preferences, which can facilitate predictions of conditions favoring persistence and success. Multivariate habitat models of movements and dive behavior of narwhals (Monodon monoceros, Linnaeus) in the...

TUSK: A Framework for Overviewing the Performance of F0 Estimators

This article presents a framework for overviewing the performance of fundamental frequency (F0) estimators and evaluates its effectiveness. Over the past few decades, many F0 estimators and evaluation indices have been proposed and have been evaluated using various speech databases. In speech analysis/synthesis research, modern estimators are used as the algorithm to fulfill the demand for high...
