Bony fish genomes: Status and gaps

Journal of Fish Biology, EarlyView.
Abstract Bony fish constitute an exceptionally species‐rich group of aquatic vertebrates, comprising more than 95% of all living fish. The adaptive processes on the diversity of environments they inhabit make them a highly diverse group from taxonomic, morphological and evolutionary standpoints.

Environmental and geological controls on the diversity and distribution of the sauropodomorpha

, 2010
Sauropodomorph dinosaurs were an important component of Mesozoic terrestrial ecosystems. Their diversity and abundance fluctuated throughout the Mesozoic but whether this reflects genuine biological changes or merely variations in our sampling of the ...

Time‐calibrated relationships of a rare cave catfish (Trichomycterus rubbioli): Shedding light on troglobitic lifestyle origin in the Brazilian caatinga

Journal of Fish Biology, EarlyView.
Abstract Catfishes of the subfamily Trichomycterinae comprise the most diverse fish group with species adapted to live in Neotropical caves, but past evolutionary scenarios that have driven the origin of these troglobitic species remain unknown. We herein investigate the phylogenetic position of the cave‐restricted Trichomycterus rubbioli, endemic to ...

Orchid genome evolution and trait innovation

Journal of Integrative Plant Biology, EarlyView.
Orchids became one of the world's most diverse plant groups through genome‐driven innovations, unique relationships with fungi and pollinators, and remarkable adaptability. This review explains the origins of orchids and the evolution of their distinctive life forms, flowers, and ecological strategies and highlights promising directions for future ...

The cuticle micromorphology of extant and fossil plants as indicator of environmental conditions. A pioneer study on the influence of volcanic gases on the cuticle structure in extant plants

, 2011
The leaves of many tracheophytes are covered with a cuticle, an extracellular membrane covering aerial organs of plants. The gas exchanges between the plant and the surrounding atmosphere are mediated by the cuticle; its acts as the main barrier to air ...

Endocranial anatomy of the earliest Cretaceous European neosuchian crocodyliform Pholidosaurus purbeckensis provides new evidence for the ecological evolution of Pholidosauridae

Journal of Anatomy, EarlyView.
We present new insights into the internal cranial anatomy of the neosuchian crocodyliform Pholidosaurus purbeckensis, based on CT‐scan data of material from the lowermost Cretaceous Purbeck Limestone Group, southern UK. From the study of the endocast, we obtained new information on the phylogeny and the ecological evolution of the Family ...
