Baleen hormone analyses reveal stress and reproductive life-history of the critically endangered Rice's whale (Balaenoptera ricei). [PDF]
PLoS ONEThe Rice's whale (Balaenoptera ricei) is a recently described species of baleen whale found in the Gulf of Mexico. With fewer than 50 adults remaining, the Rice's whale is the most endangered baleen whale species.

A new Early Oligocene toothed ‘baleen’ whale (Mysticeti: Aetiocetidae) from western North America: one of the oldest and the smallest [PDF]
Royal Society Open Science, 2015 Archaic toothed mysticetes represent the evolutionary transition from raptorial to bulk filter feeding in baleen whales. Aetiocetids, in particular, preserve an intermediate morphological stage in which teeth functioned alongside a precursor of baleen ...

Integrating Multiple Data Sources Improves Abundance Estimation in Spatial Capture-Recapture Models. [PDF]
Ecol EvolThis study demonstrates how integrating multiple data streams improves abundance estimation for a wide‐ranging marine population, eastern North Pacific blue whales. The application of this approach is valuable to accurately track population size which is critical to guide conservation and management strategies.

Surviving a Dark Age: The Oldest Baleen-Bearing Whales (Cetacea: Chaeomysticeti) of Pacific South America (Lower Miocene, Peru) [PDF]
LifeThe evolution of baleen whales (Mysticeti) comprises two main phases, namely, (i) a Paleogene phase, which saw the diversification of stem lineages, and (ii) a Neogene phase, dominated by modern-looking, toothless, baleen-bearing forms in the ...

Migrating baleen whales transport high-latitude nutrients to tropical and subtropical ecosystems [PDF]
Nature CommunicationsBaleen whales migrate from productive high-latitude feeding grounds to usually oligotrophic tropical and subtropical reproductive winter grounds, translocating limiting nutrients across ecosystem boundaries in their bodies.

Assessing changing baleen whale distributions and reported incidents relative to vessel activity in the Northwest Atlantic. [PDF]
PLoS ONEBaleen whales are among the largest marine megafauna, and while mostly well-protected from direct exploitation, they are increasingly affected by vessel traffic, interactions with fisheries, and climate change.
