Widespread Occurrence of Chemical Residues in Beehive Matrices from Apiaries Located in Different Landscapes of Western France
TLDR
Honey bees, honeys and pollens are appropriate sentinels for monitoring pesticide and veterinary drug environmental pollution and the widespread occurrence of multiple residues in beehive matrices suggests a potential issue with the effects of these residues alone or in combination on bee health.
Multi-residue analysis of 80 environmental contaminants in honeys, honeybees and pollens by one extraction procedure followed by liquid and gas chromatography coupled with mass spectrometric
TLDR
A multi residue analysis was developed to quantify 80 environmental contaminants, pesticides and veterinary drugs, belonging to different chemical classes, in honeys, honeybees and pollens and application to more than 100 samples of each matrix was achieved for a global view of pesticide presence in the honeybee environment.
The giant bite of a new raptorial sperm whale from the Miocene epoch of Peru
TLDR
It is proposed that Leviathan fed mostly on high-energy content medium-size baleen whales, together with the contemporaneous giant shark Carcharocles megalodon, which had a profound impact on the structuring of Miocene marine communities.

PHYLOGENETIC AFFINITIES OF THE LONG‐SNOUTED DOLPHIN EURHINODELPHIS (CETACEA, ODONTOCETI) FROM THE MIOCENE OF ANTWERP, BELGIUM
TLDR
The main results of the cladistic analyses are a sister-group relationship between E. cocheteuxi and the extant family Ziphiidae, and a more basal position of the superfamily Physeteroidea (sperm whales) in the tree.
A New Porpoise (Cetacea, Odontoceti, Phocoenidae) from the Pliocene of the North Sea
TLDR
The description of a new genus and species of porpoise (Odontoceti, Phocoenidae), Septemtriocetus bosselaersi, which is the first clear record of a fossil phocoenid from the North Atlantic, suggests an initial early to early late Pliocene north dispersal via the Arctic Ocean to the NorthAtlantic for the lineage of SeptemTriocetus.
Bees, honey and pollen as sentinels for lead environmental contamination.
TLDR
Three beehive matrices, sampled in eighteen apiaries from West France, were analysed for the presence of lead (Pb), and Apiaries in urban and hedgerow landscapes appeared more contaminated than apiaries in cultivated and island landscapes.
Huaridelphis raimondii, a New Early Miocene Squalodelphinidae (Cetacea, Odontoceti) from the Chilcatay Formation, Peru
ABSTRACT The fossil record of odontocetes (toothed cetaceans) is relatively scarce during the Oligocene and early Miocene compared with later in the Miocene and Pliocene; most of the odontocete
Macroraptorial sperm whales (Cetacea, Odontoceti, Physeteroidea) from the Miocene of Peru
TLDR
A phylogenetic analysis based on 53 characters and 21 physeteroid species confirms the monophyly of Acrophyseter and groups this genus with the larger, middle to late Miocene macroraptorial stem physeteroids Brygmophyseter and Zygophyseter.
Plasticity and Convergence in the Evolution of Short-Necked Plesiosaurs
TLDR
It is shown that pliosaurids iteratively evolved polycotylid-like cranial morphologies from the Early Jurassic until the Early Cretaceous, and the existence of an optimal ecomorphology for short-necked piscivorous plesiosaurs through time and across phylogeny is suggested.
