Does salinity make a difference—Kidney anatomy of Saimaa (Pusa saimensis) and Baltic ringed seals (Pusa hispida botnica)

open access: yesThe Anatomical Record, EarlyView.
Abstract As habitat salinity markedly differs between the endangered, freshwater‐dwelling Saimaa ringed seal (Pusa saimensis Nordquist, 1899) and the brackish water‐inhabiting Baltic ringed seal (Pusa hispida botnica Gmelin, 1788), we investigated whether this difference has resulted in morphological changes to their kidneys.

L'application en mer de la directive "Habitats"

open access: yes, 2015
Le réseau « Natura 2000 » constitue le cœur de la politique européenne de protection de l’environnement. Mis en place dans le cadre de la directive « Habitats » du 21 mai 1992 , il confie aux Etats membres la création de « Zones spéciales de conservation » (les célèbres zones Natura 2000) destinées à protéger les écosystèmes les plus fragiles situés ...

La mise en oeuvre de la Directive Habitats.

open access: yes, 2007
Il s'agit de proposer une méthode d'aide à la gestion de la biodiversité. Elle vise au maintien à long terme, grâce à une démarche territoriale, des habitats prioritaires et des habitats conditionnant la vie des espèces prioritaires sur des territoires où les données descriptives du milieu ont déjà été consignées.

The skeleton of the green Iguana iguana (Squamata: Iguanidae) and its intraspecific morphological variation

open access: yesThe Anatomical Record, EarlyView.
Abstract The green iguana (Iguana iguana) is an iguanine lizard with herbivorous and arboreal habits, whose distribution spans through South America, Central America to the south of North America. Although the genus Iguana is well‐known, the species still lacks a comprehensive and up‐to‐date anatomical study, particularly addressing the axial skeleton,

Comparative cranial biomechanics reveal macroevolutionary trends in theropod dinosaurs, with emphasis on Tyrannosauroidea

open access: yesThe Anatomical Record, EarlyView.
Abstract Tyrannosaurus is viewed as a model organism in vertebrate paleontology, with numerous studies analyzing its feeding biomechanics. Nonetheless, the evolution of this feeding performance has been under‐addressed in Tyrannosauroidea, especially in basal tyrannosauroids. Here we used muscle‐force reconstruction and finite element analysis (FEA) to
