The last Palaeoproteus (Urodela: Batrachosauroididae) of Europe

Vasilyan, Davit ; Yanenko, Vadym

In: Scientific Reports, 2020, vol. 10, p. 2733

The Batrachosauroididae are an enigmatic group of salamanders known from the Cretaceous and Tertiary of North America and Europe. In Europe, the family is known only by two species of the genus Palaeoproteus. The genus has limited distribution in Western and Central Europe. In the present paper, we describe a new species, Palaeoproteus miocenicus, from the early late Miocene (11–9 Ma) of...

Colchero, Fernando ; Jones, Owen R. ; Conde, Dalia A. ; Hodgson, David ; Zajitschek, Felix ; Schmidt, Benedikt R. ; Malo, Aurelio F. ; Alberts, Susan C. ; Becker, Peter H. ; Bouwhuis, Sandra ; Bronikowski, Anne M. ; Vleeschouwer, Kristel M. ; Delahay, Richard J. ; Dummermuth, Stefan ; Fernández‐Duque, Eduardo ; Frisenvænge, John ; Hesselsøe, Martin ; Larson, Sam ; Lemaître, Jean‐François ; McDonald, Jennifer ; Miller, David A.W. ; O'Donnell, Colin ; Packer, Craig ; Raboy, Becky E. ; Reading, Chris J. ; Wapstra, Erik ; Weimerskirch, Henri ; While, Geoffrey M. ; Baudisch, Annette ; Flatt, Thomas ; Coulson, Tim ; Gaillard, Jean‐Michel

The current extinction and climate change crises pressure us to predict population dynamics with ever‐greater accuracy. Although predictions rest on the well‐advanced theory of age‐structured populations, two key issues remain poorly explored. Specifically, how the age‐dependency in demographic rates and the year‐to‐year interactions between survival and fecundity affect...

Cranial ontogenetic variation in early saurischians and the role of heterochrony in the diversification of predatory dinosaurs

Foth​, Christian ; Hedrick, Brandon P. ; Ezcurra, Martin D.

In: PeerJ, 2016, vol. 4, p. e1589

Non-avian saurischian skulls underwent at least 165 million years of evolution and shapes varied from elongated skulls, such as in the theropod Coelophysis, to short and box-shaped skulls, such as in the sauropod Camarasaurus. A number of factors have long been considered to drive skull shape, including phylogeny, dietary preferences and functional constraints. However, heterochrony is...

The Dynamics and Evolution of the Service Marketing Literature: 1993-2003

Furrer, Olivier ; Sollberger, Pierre

In: Service Business, 2007, vol. 1, p. 93-117

This article analyzes service research published in marketing journals between 1993 and 2003. Two levels of analysis of the dynamics and evolution of the service marketing literature are distinguished: first, the dynamics of specific themes of the service marketing literature, and second, the structural evolution of these themes. Through a content analysis, we study the dynamics of individual...

Vertragsfreiheit im 19. Jahrhundert – Mythologie und das Schweigen der Quellen : Rezensions-Essay zu Sibylle Hofer: Freiheit ohne Grenzen? privatrechtstheoretische Diskussionen im 19. Jahrhundert, Mohr (Siebeck): Tübingen 2001, 313 pp., Jus Publicum Vol. 53, ISBN 3-16-147576-3 = Freedom of Contract in the 19th Century: Mythology and the Silence of the Sources

Abegg, Andreas

In: Zeitschrift für Schweizerisches Recht, 2005, vol. 1, p. 73

Der Autor rezensiert die Habilitationsschrift von Hofer zur Vertragsfreiheit im 19. Jahrhundert und lobt deren wissenschaftliche Erfassung der privatrechtlichen Freiheitskonzeptionen des 19. Jahrhunderts. Allerdings blendet Hofer die gesellschaftlichen Kontexte des 19. Jahrhunderts fast vollständig aus, womit sie die späte diskursive Emergenz der Vertragsfreiheit um 1900 und deren...
