A new species of the neopterygian fish Enchodus from the Duwi Formation, Campanian, Late Cretaceous, Western Desert, central Egypt [PDF]

Acta Palaeontologica Polonica, 2017
The neopterygian fish Enchodus was a widespread, speciose genus consisting of approximately 30 recognized species that were temporally distributed from the late Early Cretaceous through the Paleocene.

Growth, age and size of the Jurassic pachycormid Leedsichthys problematicus (Osteichthyes: Actinopterygii) [PDF]

, 2013
The Jurassic pachycormid osteichthyan Leedsichthys problematicus is renowned for having been able to achieve prodigious size for a bony fish. Building on work of MARTILL (1986a), a thorough examination of all known material was conducted in order to ...

The Pathophysiological Functions of Heparanases: From Evolution, Structural and Tissue‐Specific Perspectives

The FASEB Journal, Volume 39, Issue 17, 15 September 2025.
Heparanase 1 (HPSE1) and Heparanase 2 (HPSE2) exhibit opposing expression patterns and functions in pathological contexts, such as cancer. Here, we describe their specific expression in immune cells and their implications in skin diseases. Although they are structurally similar and considered to be ‘cousins’, we found no common ancestor and that HPSE2 ...

Diversity of immunoglobulin light chain genes in non-teleost ray-finned fish uncovers IgL subdivision into five ancient isotypes [PDF]

, 2018
The aim of this study was to fill important gaps in the evolutionary history of immunoglobulins by examining the structure and diversity of IgL genes in non-teleost ray-finned fish.

Habitat Availability, Jurassic and Cretaceous Origins of the Deep‐Bodied Shark Morphotype and the Rise of Pelagic Sharks

Ecology and Evolution, Volume 15, Issue 9, September 2025.
We find support for a benthic origin of sharks, with four discrete transitions towards pelagic‐type morphology occurring during the Jurassic and Cretaceous. Increased habitat availability driven by biotic and abiotic environmental change may have driven shifts towards pelagic‐type morphology. These results may help explain discordance between molecular

Hybrid genome assembly and annotation of Danionella translucida [PDF]

, 2019
Studying neuronal circuits at cellular resolution is very challenging in vertebrates due to the size and optical turbidity of their brains. Danionella translucida, a close relative of zebrafish, was recently introduced as a model organism for ...

A Compendium of Bona Fide Reference Markers for Genuine Plant Extracellular Vesicles and Their Degree of Phylogenetic Conservation

Journal of Extracellular Vesicles, Volume 14, Issue 9, September 2025.
ABSTRACT Although the field of plant EVs (PEVs) is experiencing exponential growth, rigorous characterisation complying with MISEV guidelines has not been yet implemented due to the lack of bona fide reference markers. In this work, we have paved the way for the standardisation of PEV markers, providing the most profound proteomic data so far from ...

Biotic Mechanisms Strengthen Functional and Phylogenetic Convergence of Reef Fish Assemblages at Higher Latitudes

Journal of Biogeography, Volume 52, Issue 9, September 2025.
ABSTRACT Aim How communities of organisms come together has long fascinated scientists, with renewed interest in using functional and evolutionary patterns to infer mechanisms of community assembly. Ecological theory predicts that biotic interactions could lead to either divergence in the event of niche partitioning or convergence through the exclusion
