Advances in Bioinspired Interfacial Adhesion with Frictional Enhancement: From Fundamental Research to Biomimetic Applications

Small Structures, Volume 7, Issue 2, February 2026.
Biological models in nature reveal remarkable friction‐adhesion mechanisms, driven by intermolecular forces and suction. Researchers leverage these principles to design advanced materials with enhanced adhesion properties. By optimizing these materials under stimuli like light and electricity, new solutions emerge for regulating interface interactions ...

Morphology and paleoecology of a hybodontiform with serrated teeth, Priohybodus arambourgi, from the Late Jurassic of northeastern Brazil

The Anatomical Record, Volume 309, Issue 1, Page 5-32, January 2026.
Abstract Hybodontiformes was a diverse, successful, and important group of shark‐like chondrichthyans known from a variety of ecosystems. Some representatives of the order had a wide palaeogeographic distribution, as is the case with Priohybodus arambourgi. With a multicuspidate crown, P. arambourgi was the first hybodontiform to develop fully serrated

Effects of Lateral Hydrological Connectivity on the Taxonomic and Functional Structure of Fish Communities in Saône River Floodplains (France): Implications for Non‐Native Species Distribution

Freshwater Biology, Volume 71, Issue 1, January 2026.
ABSTRACT Large alluvial plain rivers provide a complex mosaic of freshwater habitats characterised by a lateral hydrological connectivity (LHC) gradient between the main channel and floodplains. This connectivity plays a key role in structuring aquatic communities, influencing species distribution, diversity, and ecosystem processes.

Ovarian organization and maturity stages of armored catfish Hypostomus strigaticeps (Siluriformes, Loriicaridae)

, 2022
This work studied the ovarian development of the armored catfish Hypostomus strigaticeps. Between July 2002 and June 2005, 332 females were collected monthly from the Corumbataí River, São Paulo State - Brazil. The ovaries were processed using routine histological techniques - paraffin inclusion and 5 μm thick sections stained in hematoxylin-eosin. Six

Occurrence of suckermouth armored catfish (Siluriformes, Loricariidae, Pterygoplichthys) in inland waters of Israel

BioInvasions Records, 2013
Specimens of the South American suckermouth armored catfish genus Pterygoplichthys were recently (2011-2012) collected in inland waters of Israel, namely, Lake Kinneret (Sea of Galilee) and Nahal Amal ("Amal Stream"). Based mainly on color patterns, at least two different species, P. disjunctivus and P. pardalis, are included but there is a possibility
