Quality Control Measures for Enhancing Confidence in Nanoscale IR Spectroscopy
Geostandards and Geoanalytical Research, EarlyView.Key Points Common lab materials and sample handling may introduce molecular and particulate contaminants detectable by PiFM. We present a spectral database of common contaminant signatures to support accurate nanoscale analysis. We provide practical guidelines to improve preparation, handling, and storage of samples to mitigate contamination, ensuring ...

The magnitude of cryptic insect diversity in one tropical rainforest
Insect Conservation and Diversity, EarlyView.We detected 214 cryptic species out of a total of 2006 species (10.6%) examined from 22 focal insect taxa in 1500 ha tropical rainforest in Panama. The percentage of cryptic species varied greatly among assemblages (0%–19%), with half of the assemblages devoid of cryptic species and the highest proportions of cryptics in Pieridae and Formicidae ...

, 2006 Longevity of a taxonomic group is an important issue in understanding the dynamics of evolution. In this respect a key observation is that genera, families or orders can each be assigned a characteristic average lifetime [Van Valen, L., (1973 ...

Journal of Anatomy, Volume 246, Issue 4, Page 558-574, April 2025.Here, we present the most complete dataset to date on the endosseous labyrinths of extant crocodylians. Using 3D geometric morphometrics, we show that allometry constitutes a major contributor of the shape variation of the crocodylian endosseous labyrinths and that the development of this structure is likely linked to the braincase conformation, in all

The origin and evolution of air sacs in pterosaurs and their forerunners
Journal of Anatomy, EarlyView.Pneumatized pterosauromorph vertebrae and their phylogenetic context. Abstract Although the existence of postcranial pneumaticity and the inferred presence of air sacs connected to the lungs are well established in Pterosauria, the origin of this system in pterosaurs remains unclear. We investigated skeletal pneumaticity in the Triassic pterosauromorph

The histology of rhynchosaur (Diapsida, Archosauromorpha) ankylothecodonty
Journal of Anatomy, EarlyView.Dental evolution is a major topic in vertebrate palaeontology and provides key insights into the evolutionary history of several amniote clades. This study investigates rhynchosaur ankylothecodonty within the broader evolutionary context of Archosauromorpha.
