Cetacean relaxin. Isolation and sequence of relaxins from Balaenoptera acutorostrata and Balaenoptera edeni.

Cetacean diversity on the Parnaiba Delta, Maranhão state, northeastern Brazil.

The increase in the research of cetacean surveys on the Brazilian coast has brought new data on the distribution of species never reported before. The present work reviews the current knowledge on cetaceans species and extends this knowledge with an analysis of cetaceans stranded in the Parnaiba Delta, on the coast of Maranhão State, Brazil. The studies on cetacean diversity on the coast of the...

First molecular determination of herpesvirus from two mysticete species stranded in the Mediterranean Sea

BACKGROUND Herpesvirus can infect a wide range of animal species: mammals, birds, reptiles, fish, amphibians and bivalves. In marine mammals, several alpha- and gammaherpesvirus have been identified in some cetaceans and pinnipeds species. To date, however, this virus has not been detected in any member of the Balaenoptera genus. CASE PRESENTATION Herpesvirus was determined by molecular metho...

Cetacean distribution and relative abundance in Colombia’s Pacific EEZ from survey cruises and platforms of opportunity

Cetacean sighting data collected under various programmes in Colombian Pacific waters were collated with the goal of assessing the distribution and abundance patterns of all species occurring in the exclusive economic zone (EEZ). Distribution maps are presented for 19 species and one genus based on 603 sightings collected between 1986 and 2008. Ordered by sighting frequency, these species were:...

Acoustic ecology and behavior of minke whales in the Hawaiian and Marianas islands: localization, abundance estimation, and characterization of minke whale "boings".

Balaenoptera acutorostrata (minke whale) is a small and elusive baleen whale that is rarely sighted in the tropical waters of the North Pacific Ocean. During winter and spring, complex sounds called ”boings” are frequently detected around the Hawaiian Islands and other Pacific island regions (Norris et al. 2009 ; Thompson and Friedl 1982 ) . Although boings were described over 45 years ago (Wen...
