Le Cénomanien : étage des serpents bipèdes
Trois serpents munis de pattes sont connus: Pachyrhachis problematicus, Haasiophis terrasanctus et Eupodophis descouensi. Ils possèdent des membres et une ceinture postérieurs mais n'ont ni ceinture ni membres antérieurs, c'est-à-dire qu'ils sont bipèdes.

ABSTRACT When it comes to making planning and development decisions, the concepts of small, medium‐sized, or large cities are sometimes used to adapt public policies and instruments, or even to highlight challenges that are specific to certain categories of city. In this article, we take a look at the various dimensions that can be used to characterize

Beyond the present: How climate change is relevant to pest risk analysis
Abstract Climate change is widely recognized as a critical global challenge with far‐reaching consequences. It affects pest species by altering their population dynamics, actual and potential distribution areas, as well as interactions with their hosts and natural enemies. Climate change thus has potentially important implications for multiple areas of

Modelling tools for including climate change in pest risk assessments
Abstract This paper provides a comprehensive overview of the modelling tools available for integrating climate change impacts into pest risk assessments (PRA), elucidating the existing methodologies and models employed to understand the potential distributions of pests based on historical data and under future climate change scenarios. We highlight the
