Les Methanomassiliicoccales (MX) sont des archées méthanogènes hydrogénotrophes méthyle-dépendantes (MHMD) réparties en deux clusters phylogénétiques reflétant leurs adaptations aux écosystèmes digestifs (host-associated) ou non-digestifs (free-living). Nos connaissances les concernant se limitent surtout à des études centrées sur des milieux digestifs.

Abstract Arhinolemur scalabrinii† Ameghino, 1898 was originally described as a strepsirrhine primate (Mammalia) but has been recognized as an anostomid fish since 2012. It remains the only extinct anostomid species known from complete cranial material.

Clade‐wide morphological and functional variation of the sauropsid columella
Abstract The columella (=stapes) is the middle ear bone of reptiles that transmits vibrations from the environment to the inner ear. It has been shown to exhibit extensive interspecific morphological disparity in several clades; however, its morphological variation and associated functional consequences remain poorly described.

The study of fish growth is a valuable tool in providing good understanding on the general biology and growth of fish populations, in addition to the comparison of the same fish species populations living in remote geographic areas.

It is widely accepted that obligate aquatic mammals, specifically toothed whales, rely relatively little on olfaction. There is less agreement about the importance of smell among aquatic mammals with residual ties to land, such as pinnipeds and sea ...

Segmental composition and nerve distribution of the brachial plexus in Galictis cuja
Abstract Galictis cuja is a neotropical mustelid with terrestrial locomotor habits, yet the anatomy of its brachial plexus has remained undescribed. This study characterizes the origin, organization, and distribution of the brachial plexus nerves in 15 adult specimens (30 antimeres).

Drivers of tail evolution in squamates and their implications for the fossorial origin of snakes
Abstract The axial skeleton serves as the primary structural support in all vertebrates and is subdivided into five distinct regions: cervical, thoracic, lumbar, sacral, and caudal. Relaxation of constraints acting on the terminal end of the axial skeleton has led to remarkable variation in caudal vertebrae number across Squamata.

Studies on methanogenesis from freshwater sediments have so far primarily focused on lake sediments. To expand our knowledge on the community composition of methanogenic archaea in river sediments, we studied the abundance and diversity of methanogenic ...

Trophic ecology of a tropical aquatic and terrestrial food web: insights from stable isotopes (15N)
We used stable isotope analysis (15N/14N) to characterize the trophic relationships of consumer communities of an aquatic food web (a permanent pond) and the adjacent terrestrial food web (secondary dry dipterocarp forest) from a seasonal tropical field site in north-eastern Thailand.
