Adapting to a warmer ocean – seasonal shift of baleen whale movements over three decades [PDF]

, 2015
Date of Acceptance: 11/02/2015Global warming poses particular challenges to migratory species, which face changes to the multiple environments occupied during migration. For many species, the timing of migration between summer and winter grounds and also

What do humpback whales Megaptera novaeangliae (Cetartiodactyla: Balaenopteridae) pairs do after tagging?

Zoologia (Curitiba), 2014
The social structure of humpback whales in their tropical wintering grounds is very fluid. To date, no information has been published for cases in which two whales were both satellite-tagged while in association.

Maximizing eDNA detections of rare marine organisms: A case study of a delphinid species

Methods in Ecology and Evolution, EarlyView.
Abstract Environmental DNA (eDNA) is an emerging tool for surveying marine organisms. Advances in molecular assay designs and bioinformatic methods provide new opportunities for detecting rare species; however, overcoming methodological challenges of rare species detection remains an important obstacle for the widespread deployment of eDNA methods for ...

A Note on Suckling Behavior and Laterality in Nursing Humpback Whale Calves from Underwater Observations

Animals, 2017
We investigated nursing behavior on the Hawaiian breeding grounds for first year humpback whale (Megaptera novaeangliae) calves. We observed and video-documented underwater events with nursing behavior from five different whale groups.
