The Anatomical Record, Volume 309, Issue 3, Page 550-602, March 2026.Abstract Actinopterygii is a major extant vertebrate group, but limited data are available for its earliest members. Here we investigate the morphology of Devonian actinopterygians, focusing on the lower jaw. We use X‐ray computed tomography (XCT) to provide comprehensive descriptions of the mandibles of 19 species, which span the whole of the Devonian

Effect of aerial O-2 partial pressure on bimodal gas exchange and air-breathing behaviour in Trichogaster leeri [PDF]
, 2007 © The Company of Biologists Ltd 2007The effects of experimental alterations of aerial O2 partial pressure (PO2,air) on bimodal gas exchange and airbreathing behaviour were investigated in the aquatic airbreathing fish Trichogaster leeri in normoxic water.

Exploring Larval Axolotl Brain Development: Insights Into Developmental and Functional Constraints
Evolution &Development, Volume 28, Issue 1, March 2026.We studied brain shape and volume variations during larval development of the Mexican axolotl. Modularity, morphological integration, and allometric regressions supported both mosaic and concerted evolution models, highlighting a complex interplay of constraints during axolotl ontogeny.

Tetraodon genome confirms Takifugu findings : most fish are ancient polyploids [PDF]
, 2004 An evolutionary hypothesis suggested by studies of the genome of the tiger pufferfish Takifugu rubripes has now been confirmed by comparison with the genome of a close relative, the spotted green pufferfish Tetraodon nigroviridis.

The cognitive role of concept variability
Mind &Language, Volume 41, Issue 1, Page 66-87, February 2026.I present and defend concept variability, the view that concepts can admit of indefinitely many variations and changes in their representational contents without thereby losing their identity. I argue that the variability of concepts is central to their role in enabling cognition, and thus that a concept's content variability is, despite philosophical ...

Journal of the Association for Information Science and Technology, Volume 77, Issue 1, Page 198-223, January 2026.Abstract The term semantic primitives refers to a set of basic, atomic concepts from which all other (compound) concepts are constructed. It presupposes the principle of compositionality—the idea that complex items or expressions can be formed by combining simpler constituents.
