How off the press: Hollers et al. quantify the energetic consequences of going from rest to non-resting in humpback whales. Super helpful when evaluating impacts of disturbance academic.oup.com/conphys/arti... www.mmrphawaii.org/post/new-pub... @conphysjournal.bsky.social

New publication: Energetic benefits of resting behaviour in humpback whale mother–calf pairs revealed by biologging and UAS-photogrammetry

We are excited to share our newest publication in Conservation Physiology on humpback whale mother-calf energetics written by PhD candidate Gussie Hollers and coauthors! Link to the full paper: doi.or...

New paper! Lead author @noemiefreymond.bsky.social used a hybrid approach combining tag data & physical modelling to show that the timing & hydrodynamic effects of bubble releases by sperm whales during drift dives indicate deliberate & active buoyancy regulation, even during sleep.

Sperm whales rest in an unusual position, sleeping vertically underwater. In their recent paper, Freymond & co show that the whales blow bubbles in their sleep to keep themselves from shooting to the surface, letting them sleep soundly beneath the waves doi.org/10.1242/jeb....

Hawaii’s humpback whales like to steal the spotlight, but their cousins the false killer whales desperately need our help. www.iflscience.com/nutritional-... #marmam

False Killer Whales In One Of The Last Groups On Earth Are Declining Fast At 3.5 Percent Per Year – Heatwaves And Prey Shortages To Blame

The first-ever study of body condition in these whales had some concerning findings, including one individual that lost over 200 kilograms in just 10 weeks.

NEW: NSF has been funding research at a fraction of its historic rate. Last week, the agency finally began distributing money to its directorates and is now likely to pick up the grantmaking pace. But these allocations also amount to substantial cuts across the sciences. My reporting:

Delays have kept new NSF grants to a trickle — that could be about to change

The agency is finally ready to distribute a spate of new grants, but it is also preparing substantial cuts to areas such as biological and social sciences.

Did you hear the good news? The House has pulled the ESA Amendments Act (H.R. 1897) from the floor after facing unexpected opposition, including from several Republican members. The bill aimed to weaken parts of the Endangered Species Act, especially around how protections can impact development.

New paper alert! Alexandra Vanderzee found that AnyDorsal can effectively identify Risso's dolphins. This is a fun result because a) AnyDorsal wasn't trained on Risso's and b) it shows AnyDorsal can balance scars dorsal notches as separate ID information onlinelibrary.wiley.com/doi/10.1111/...

New! Longer body size means more female calves in baleen whales! By Zoe Rand, Sarah Converse and myself Paper: royalsocietypublishing.org/doi/10.1098/... Press: www.washington.edu/news/2025/09...

Longer body size means more female calves for baleen whale moms

University of Washington researchers found, in historical whaling data, that longer baleen whale mothers were more likely to birth female calves than males. These results run contrary to a leading...

New collaborative research out today with @raincoast.org explores the deep-roots of conflict over killer whale and Chinook management in the Salish Sea - proposing new approaches to transform intractable conflicts. www.timescolonist.com/environment/...

Study reveals anglers, conservationists share surprising common ground in orca-chinook fight

Amid debate over protecting chinook salmon for southern resident killer whales, a study found anglers and conservationists share key values, which could resolve the conflict.

Impressive work by Cam Nemeth (not on BlueSky). We hypothesized that the significant lift force produced by the humpback whale’s large pectoral flippers result in them being the only species executing tight, high-speed, sustained turns characteristic of bubble-net feeding doi.org/10.1242/jeb....

The key to bubble-net feeding: how humpback whale morphology functionally differs from other baleen whales

Summary: Humpback whale turning performance during solitary bubble-net feeding exceeds the observed capabilities of other baleen whales.

You can find the first JEB additional language abstract by Cameron Nemeth and colleagues in #Hawaiian accompanying their paper, The key to bubble-net feeding: how humpback whale morphology functionally differs from other baleen whales at journals.biologists.com/jeb/article/...

Screenshot of the Research Article, The key to bubble-net feeding: how humpback whale morphology functionally differs from other baleen whales, by Cameron Nemeth, William T. Gough, Paolo S. Segre, Frank E. Fish, Andrew Szabo et al. The publishing information states: © 2025. Published by The Company of Biologists | Journal of Experimental Biology (2025) 228, jeb249607. doi:10.1242/jeb.249607. The first line of the Abstract reads, 'Maneuverability in cetaceans is facilitated by pectoral flippers, flukes and spinal flexibility, features that are pronounced in humpback whales (Megaptera novaeangliae).'. The Research article includes an Additional Language Abstract, in Hawaiian. The first sentence of the Additional Language Abstract reads, 'Kōkua ʻia ka huli ʻana o nā cetaceans e ka ʻēheu, hiʻu a me ka palupalu o ka iwikuamoʻo, ahuwale nō kēia mau mea i ke koholā (Megaptera novaeangliae)'.
