Journal of Comparative Neurology, Volume 531, Issue 2, Page 314-335, February 2023., 2023 The main objective of this work was to obtain detailed information on the distribution and localization of the spexin (Spx) system in the sea bass brain. To this purpose, we first identified and characterized the spx1 gene and analyzed its expression in the central nervous system (CNS) of the European sea bass by using quantitative Real‐Time Polymerase

The Critical Beta-splitting Random Tree IV: Mellin analysis of Leaf Height [PDF]
arXivIn the critical beta-splitting model of a random $n$-leaf rooted tree, clades are recursively split into sub-clades, and a clade of $m$ leaves is split into sub-clades containing $i$ and $m-i$ leaves with probabilities $\propto 1/(i(m-i))$. The height of a uniform random leaf can be represented as the absorption time of a certain {\em harmonic descent}

Structure and evolution of neuronal wiring receptors and ligands
Developmental Dynamics, Volume 252, Issue 1, Page 27-60, January 2023., 2023 Abstract One of the fundamental properties of a neuronal circuit is the map of its connections. The cellular and developmental processes that allow for the growth of axons and dendrites, selection of synaptic targets, and formation of functional synapses use neuronal surface receptors and their interactions with other surface receptors, secreted ...

A new Crocodyloidea from the middle Eocene of Zamora (Duero Basin, Spain)
The Anatomical Record, EarlyView.Abstract The eusuchian crocodyliforms recorded in the Eocene levels of the Spanish Duero Basin belong to three lineages: Planocraniidae, with the species Duerosuchus piscator; Alligatoroidea, represented by several specimens of the genus Diplocynodon; and Crocodyloidea, which includes several specimens traditionally attributed to Asiatosuchus.

A bothremydid turtle (Pleurodira) from the middle Cenomanian of Vale de Figueira (Belas, Portugal)
The Anatomical Record, EarlyView.Abstract An unpublished turtle shell from the middle Cenomanian of Vale de Figueira, near Belas (Lisbon District, Portugal), is recognized by us as collected in 1880 under the direction of Carlos Ribeiro. No turtle remains from that region had so far been figured, described or discussed from a systematic point of view.
