Exploring the cranial morphology and possible convergences of Triassic non‐crocodylomorph pseudosuchians (Archosauria: Pseudosuchia) with other sauropsids through linear morphometrics

open access: yesThe Anatomical Record, EarlyView.
Abstract Triassic pseudosuchians had highly diversified cranial morphologies. These archosaurs occupied diverse ecological roles, ranging from terrestrial predators and herbivores to semiaquatic ambush predators and possible waders. Here, we apply linear cranial morphometrics to assess possible convergences with other sauropsids from the clades ...

Physiological and ecological aspects of Methanomassiliicoccales in terrestrial and aquatic environments

open access: yes, 2021
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.

Modeling pesticide and PFAS bioaccumulation in amphibians: integration of biphasic ecology and route specific uptake

open access: yesEnvironment International
Amphibians are sensitive indicators of environmental contamination due to their permeable skin and dual aquatic–terrestrial life cycle. A physiologically based kinetic (PBK) model was developed to quantify the bioaccumulation of pesticides and per- and ...

Scaling and ecomorphology of lagomorph body shape and appendicular skeleton

open access: yesThe Anatomical Record, EarlyView.
Abstract Body shape is one of the most prominent features of phenotypic variation. Yet, mammalian body shapes are poorly quantified and the underlying components contributing to its diversity and its relationship to other skeletal components are rarely tested.

Stable Isotope Analyses in Aquatic Ecology (a review) [PDF]

open access: yesЖурнал Сибирского федерального университета: Серия Биология, 2009
Theory and practice of analyses of stable isotopes of carbon and nitrogen for food trophic studies in aquatic ecology are regarded basing on literature, published primarily in the last decade.

Exceptional preservation informs the paleobiology of tapinocephalid dinocephalians

open access: yesThe Anatomical Record, EarlyView.
Abstract The tapinocephalid dinocephalian Moschops is one of the most iconic taxa of the middle Permian, yet its paleobiology remains one of the least well‐known. Here, we address some aspects of paleoneurology and paleobiology of Moschops using CT scanning of four well preserved skulls from the upper Abrahamskraal Formation of South Africa. Two of the

Inderjit, Mallik, A.U. (eds). Chemical ecology of plants: allelopathy in aquatic and terrestrial ecosystems [PDF]

open access: yesAnnals of Botany, 2003
The study of effects of one plant (including micro‐organisms) on the growth of another plant through the release of low‐molecular compounds (predominantly secondary metabolites) into the environment, defines allelopathy (Rice, 1984). Today, research in allelopathy is conducted by weed scientists, crop scientists, plant ecologists, microbial ecologists,

When morphology, molecular phylogeny and ecology do not match: some examples among aquatic and terrestrial Oniscidea

open access: yes, 2012
Most species of terrestrial Isopoda require a high degree of humidity to survive, but only a small number of species are known to live strictly or temporarily in an aquatic environment.

A new occurrence of tetrapod footprints from the Late Triassic of the Candelária Sequence, Brazil

open access: yesThe Anatomical Record, EarlyView.
Abstract The Hyperodapedon Assemblage Zone of the Candelária Sequence (Santa Maria Supersequence, Paraná Basin) preserves one of the most significant Late Triassic continental vertebrate assemblages in southern Brazil. Despite the relatively well‐documented body fossil record from this interval, ichnological records remain comparatively scarce.
