The Franciscana (Pontoporia blainvillei) in the Northern Limit of the FMA II: Strandings and Habitat Use in Ilha Grande Bay

Marine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT The presence of the franciscana (Pontoporia blainvillei) at the northern limit of the FMA II was investigated using a range of methods, including monitoring of strandings, boat surveys, and passive acoustic monitoring (PAM). Franciscana strandings were recorded within the distributional gap between Macaé (22°55′ S) and Ilha Grande (23°09′ S ...

Stable Isotope Analysis (δ13C and δ15N) of Baleen Plates Reveals Feeding Patterns in Stranded Humpback Whales (Megaptera novaeangliae) Along the Brazilian Coast

Marine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT Humpback whales (Megaptera novaeangliae) from breeding stock A migrate annually between Antarctic feeding grounds (~65° S) and Brazilian breeding areas (~17° S). Traditionally considered to fast during migration, recent feeding observations and increased strandings along southeastern Brazil (~23° S) raise questions about possible shifts in ...

THE EFFECT OF THE AGE AT FIRST CALVING ON THE LEVEL OF MILK PRODUCTION IN THE FIRST LACTATION

, 1980
The effect of the age at first calving on the level of milk production during 305 days in first lactation was investigated in 130 simmental cows. The average age first calving was 829,11 days with range from 665 to1,252 days.

Killer Whales in the Central Tropical Pacific: Occurrence, Resightings, Morphology, and Acoustics

Marine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT Compared to their well‐studied coastal temperate counterparts, killer whales (Orcinus orca) in tropical‐subtropical and oceanic areas are under‐documented. We used sighting, photo‐identification, and acoustic data of killer whales in the central tropical Pacific (CTP), collected from multiple platforms between 2002 and 2023, to assess their ...

Harbor Porpoise and Beluga Whale Habitat Use in the Saguenay‐St. Lawrence Marine Park (Canada) Revealed by a Combination of Visual and Acoustic Survey

Marine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT Studying habitat use of cetaceans that spend most of their lives underwater poses challenges, prompting the use of complementary methods. Non‐invasive methods, land‐based surveys (LBS) and passive acoustic monitoring (PAM), were used to characterize occurrence patterns of beluga whales, harbor porpoises, and vessels in the Saguenay–St ...
