Guelb el Ahmar (Bathonian, Anoual Syncline, eastern Morocco): First continental flora and fauna including mammals from the Middle Jurassic of Africa

Haddoumi, Hamid ; Allain, Ronan ; Meslouh, Said ; Metais, Grégoire ; Monbaron, Michel ; Pons, Denise ; Rage, Jean-Claude ; Vullo, Romain ; Zouhri, Samir ; Gheerbrant, Emmanuel

In: Gondwana Research, 2016, vol. 29, no. 1, p. 290–319

We report the discovery in Mesozoic continental “red beds” of Anoual Syncline, Morocco, of the new Guelb el Ahmar (GEA) fossiliferous sites in the Bathonian Anoual Formation. They produced one of the richest continental biotic assemblages from the Jurassic of Gondwana, including plants, invertebrates and vertebrates. Both the sedimentological facies and the biotic assemblage indicate a...

A new Late Agenian (MN2a, Early Miocene) fossil assemblage from Wallenried (Molasse Basin, Canton Fribourg, Switzerland)

Mennecart, Bastien ; Yerly, Bertrand ; Mojon, Pierre-Olivier ; Angelone, Chiara ; Maridet, Olivier ; Böhme, Madelaine ; Pirkenseer, Claudius

In: Paläontologische Zeitschrift, 2016, vol. 90, p. 101-123

Excavations of two fossiliferous layers in the Wallenried sand- and marl pit produced a very diversified vertebrate fauna. New material allows the reassessment of the taxonomic position of the ruminant taxa Andegameryx andegaviensis and endemic Friburgomeryx wallenriedensis. An emended diagnosis for the second species is provided and additional material of large and small mammals, as well as...

Ecophylogenetics: advances and perspectives

Mouquet, Nicolas ; Devictor, Vincent ; Meynard, Christine N. ; Munoz, Francois ; Bersier, Louis-Félix ; Chave, Jérôme ; Couteron, Pierre ; Dalecky, Ambroise ; Fontaine, Colin ; Gravel, Dominique ; Hardy, Olivier J. ; Jabot, Franck ; Lavergne, Sébastien ; Leibold, Mathew ; Mouillot, David ; Münkemüller, Tamara ; Pavoine, Sandrine ; Prinzing, Andreas ; Rodrigues, Ana S. L. ; Rohr, Rudolf P. ; Thébault, Elisa ; Thuiller, Wilfried

In: Biologial Review, 2012, vol. 87, no. 4, p. 769-785

Ecophylogenetics can be viewed as an emerging fusion of ecology, biogeography and macroevolution. This new and fast-growing field is promoting the incorporation of evolution and historical contingencies into the ecological research agenda through the widespread use of phylogenetic data. Including phylogeny into ecological thinking represents an opportunity for biologists from different fields...

Chromosomal rearrangements maintain a polymorphic supergene controlling butterfly mimicry

Joron, Mathieu ; Frezal, Lise ; Jones, Robert T. ; Chamberlain, Nicola L. ; Lee, Siu F. ; Haag, Christoph R. ; Whibley, Annabel ; Becuwe, Michel ; Baxter, Simon W. ; Ferguson, Laura ; A.Wilkinson, Paul ; Salazar, Camilo ; Davidson, Claire ; Clark, Richard ; Quail, Michael A. ; Beasley, Helen ; Glithero, Rebecca ; Lloyd, Christine ; Sims, Sarah ; Jones, Matthew C. ; Rogers, Jane ; Jiggins, Chris D. ; ffrench-Constant, Richard H.

In: Nature, 2011, p. -

Supergenes are tight clusters of loci that facilitate the co-segregation of adaptive variation, providing integrated control of complex adaptive phenotypes1. Polymorphic supergenes, in which specific combinations of traits are maintained within a single population, were first described for ‘pin’ and ‘thrum’ floral types in Primula1 and Fagopyrum2, but classic examples are also found in...

Disentangling the role of environmental and human pressures on biological invasions across Europe

Pyšek, Petr ; Jarošík, Vojtěch ; Hulme, Philip E. ; Kühn, Ingolf ; Wild, Jan ; Arianoutsou, Margarita ; Bacher, Sven ; Chiron, Francois ; Didžiulis, Viktoras ; Essl, Franz ; Genovesi, Piero ; Gherardi, Francesca ; Hejda, Martin ; Kark, Salit ; Lambdon, Philip W. ; Desprez-Loustau, Marie-Laure ; Nentwig, Wolfgang ; Pergl, Jan ; Poboljšaj, Katja ; Rabitsch, Wolfgang ; Roques, Alain ; Roy, David B. ; Shirley, Susan ; Solarz, Wojciech ; Vilà, Montserrat ; Winter, Marten

The accelerating rates of international trade, travel, and transport in the latter half of the twentieth century have led to the progressive mixing of biota from across the world and the number of species introduced to new regions continues to increase. The importance of biogeographic, climatic, economic, and demographic factors as drivers of this trend is increasingly being realized but as yet...

Status of the endangered ivory gull, Pagophila eburnea, in Greenland

Gilg, Olivier ; Boertmann, David ; Merkel, Flemming ; Aebischer, Adrian ; Sabard, Brigitte

In: Polar Biology, 2009, vol. 32, no. 9, p. 1275-1286

The ivory gull, a rare high-Arctic species whose main habitat throughout the year is sea ice, is currently listed in Greenland as ‘Vulnerable’, and as ‘Endangered’ in Canada, where the population declined by 80% in 20 years. Despite this great concern, the status of the species in Greenland has been largely unknown as it breeds in remote areas and in colonies for which population data has...

An abelisauroid (Dinosauria: Theropoda) from the early Jurassic of the high atlas mountains, Morocco, and the radiation of Ceratosaurs

Allain, Ronan ; Tykoski, Ronald ; Aquesbi, Najat ; Jalil, Nour-Eddine ; Monbaron, Michel ; Russell, Dale ; Taquet, Philippe

In: Journal of Vertebrate Paleontology, 2007, vol. 27, no. 3, p. 610–624

The fossil record of abelisauroid carnivorous dinosaurs was previously restricted to Cretaceous sediments of Gondwana and probably Europe. The discovery of an incomplete specimen of a new basal abelisauroid, Berberosaurus liassicus, gen. et sp. nov., is reported from the late Early Jurassic of Moroccan High Atlas Mountains. Phylogenetic analysis recovers Ceratosauroidea and Coelophysoidea as...

A basal sauropod dinosaur from the Early Jurassic of Morocco

Allain, Ronan ; Aquesbi, Najat ; Dejax, Jean ; Meyer, Christian ; Monbaron, Michel ; Montenat, Christian ; Richir, Philippe ; Rochdy, Mohammed ; Russell, Dale ; Taquet, Philippe

In: Comptes Rendus Palevol, 2004, vol. 3(3), p. 199

Parce que les dépôts continentaux du Jurassique inférieur affleurent rarement, l'histoire des dinosaures sauropodes est très mal connue avant la radiation des néosauropodes au Jurassique moyen. Les premiers crânes de sauropodes associés à des restes osseux bien préservés datent ainsi du Jurassique moyen. Nous rapportons ici la découverte, dans le Jurassique inférieur du Haut Atlas...
