Relationships of Cetacea (Artiodactyla) among mammals: increased taxon sampling alters interpretations of key fossils and character evolution.

PLoS ONE, 2009
BackgroundIntegration of diverse data (molecules, fossils) provides the most robust test of the phylogeny of cetaceans. Positioning key fossils is critical for reconstructing the character change from life on land to life in the water.Methodology ...

Detection of Leptospira in cane toads (Rhinella jimi) from urban and rural Paraíba, Brazil

Veterinary Record, EarlyView.
Abstract Background Leptospirosis is a significant zoonosis in tropical regions, where poor sanitation and favourable climate aid its spread. Synanthropic animals such as the cane toad (Rhinella jimi), which share environments with both people and wild and domestic animals, may harbour Leptospira and contribute to urban and rural transmission cycles ...

Vulnerability of marine megafauna to global at‐sea anthropogenic threats

Conservation Biology, EarlyView.
Abstract Marine megafauna species are affected by a wide range of anthropogenic threats. To evaluate the risk of such threats, species’ vulnerability to each threat must first be determined. We build on the existing threats classification scheme and ranking system of the International Union for Conservation of Nature (IUCN) Red List of Threatened ...

Accelerated Evolution of Limb-Related Gene Hoxd11 in the Common Ancestor of Cetaceans and Ruminants (Cetruminantia)

G3: Genes, Genomes, Genetics, 2020
Reduced numbers of carpal and tarsal bones (wrist and ankle joints) are extensively observed in the clade of Cetacea and Ruminantia (Cetruminantia). Homebox D11 (Hoxd11) is one of the important genes required for limb development in mammals. Mutations in

First At‐Sea Identifications of Ginkgo‐Toothed Beaked Whale (Mesoplodon ginkgodens): Acoustics, Genetics, and Biological Observations Off Baja California, México

Marine Mammal Science, Volume 42, Issue 1, January 2026.
ABSTRACT In 2024, an expedition was conducted off northwestern Baja California, México, to find and identify the beaked whale species that produced the BW43 echolocation pulse previously recorded in this area and elsewhere in the North Pacific. There were five Mesoplodon sightings and 21 BW43 acoustic detections on both a towed array and drifting pole ...
