Effects of changing temperature phenology on the abundance of a critically endangered baleen whale

Laura C. Ganley, Jarrett E. K. Byrnes, Daniel E. Pendleton, Charles A. Mayo et autres

Incorporating the effects of climate change in species management strategies is one of today’s greatest conservation challenges. Mechanistic models can be used to address these challenges because they explain how climate change effects cascade through ecosystems and influence species distributions. We used …

Sighting heterogeneity of right whales in the western North Atlantic: 1980-1992

Moira W. Brown, Solange Brault, Philip K. Hamilton, Robert D. Kenney et autres

The population of western North Atlantic right whales (Eubalaena glacialis) is distributed primarily between Florida, USA and NovaScotia, Canada, aggregating seasonally in five geographically distinct, high-use areas. To test the effectiveness of monitoring alldemographic classes (juvenile and adult males and females) of …

Exploring movement patterns and changing distributions of baleen whales in the western North Atlantic using a decade of passive acoustic data

Genevieve E. Davis, Mark F. Baumgartner, Peter James Corkeron, Joel T. Bell et autres

Six baleen whale species are found in the temperate western North Atlantic Ocean, with limited information existing on the distribution and movement patterns for most. There is mounting evidence of distributional shifts in many species, including marine mammals, likely because of climate-driven …

What we see is not what there is: estimating North Atlantic right whale Eubalaena glacialis local abundance

Laura C. Ganley, Solange Brault, CA Mayo

Aerial surveys can be used to estimate animal abundance, but animals unavailable for detection for portions of the survey can cause biased abundance estimates.Moreover, these biases may be variable owing to changes in behavior.We conducted focal follows to obtain surface and dive …

Distribution, demography, and behavior of North Atlantic right whales (Eubalaena glacialis) in Cape Cod Bay, Massachusetts, 1998–2013

Charles A. Mayo, Laura C. Ganley, Christine A. Hudak, Solange Brault et autres

Abstract The occurrence of North Atlantic right whales (Eubalaena glacialis) in Cape Cod Bay was documented during aerial surveys between 1998 and 2013. The seasonal occurrence remained relatively unchanged during the study, spanning the January through mid‐May timeframe. The number of individual …

Long-term passive acoustic recordings track the changing distribution of North Atlantic right whales (Eubalaena glacialis) from 2004 to 2014

Genevieve E. Davis, Mark F. Baumgartner, Julianne M. Bonnell, Joel T. Bell et autres

Given new distribution patterns of the endangered North Atlantic right whale (NARW; Eubalaena glacialis) population in recent years, an improved understanding of spatio-temporal movements are imperative for the conservation of this species. While so far visual data have provided most information on …

Nestedness and species replacement along bathymetric gradients in the deep sea reflect productivity: a test with polychaete assemblages in the oligotrophic north‐west Gulf of Mexico

Carol T. Stuart, Solange Brault, Gilbert T. Rowe, Chih‐Lin Wei et autres

Abstract Aim To test the hypothesis that low productivity drives the nestedness component of β‐diversity in polychaetes at the deep‐sea floor. Location Western Gulf of Mexico. Methods We used A. Baselga's (2010, Global Ecology and Biogeography, 19 , 134–143) metrics of species …

The importance of delineating networks by activity type in bottlenose dolphins ( Tursiops truncatus ) in Cedar Key, Florida

Stefanie K. Gazda, Swami Iyer, Timothy Killingback, Richard C. R. Connor et autres

Network analysis has proved to be a valuable tool for studying the behavioural patterns of complex social animals. Often such studies either do not distinguish between different behavioural states of the organisms or simply focus attention on a single behavioural state to …

β-diversity of deep-sea holothurians and asteroids along a bathymetric gradient (NE Atlantic)

MC Wagstaff, Kerry L. Howell, BJ Bett, DSM Billett et autres

Measuring and understanding patterns of β-diversity remain major challenges in community ecology.Recently, β-diversity has been shown to consist of 2 distinct components: (1) spatial turnover and (2) species loss leading to nestedness.Both components structure deep-sea macrofaunal assemblages but vary in importance among …

Geographic evidence for source–sink dynamics in deep‐sea neogastropods of the eastern N orth A tlantic: an approach using nested analysis

Solange Brault, Carol T. Stuart, Martine C. Wagstaff, Michael A. Rex

Abstract Aim We conduct a nested analysis of bathymetric distributions in neogastropods to test the hypothesis that bathyal and abyssal populations represent a source–sink system. Abyssal assemblages are predicted to be significantly nested subsets of bathyal assemblages, and to be characterized by …
