The costs and benefits of larger brains in fishes
Journal of Evolutionary Biology, Volume 35, Issue 7, Page 973-985, July 2022., 2022 Traits associated with brain size across fishes. Abstract The astonishing diversity of brain sizes observed across the animal kingdom is typically explained in the context of trade‐offs: the benefits of a larger brain, such as enhanced cognitive ability, are balanced against potential costs, such as increased energetic demands.

Journal of Anatomy, Volume 241, Issue 1, Page 42-66, July 2022., 2022 Coordinated cell division is important for embryonic development and for the adult body to work correctly; deregulated cell division causes diseases such as cancer. This study comprehensively investigated the expression of cell cycle control genes in the chicken embryo.

Global patterns of resilience decline in vertebrate populations
Ecology Letters, Volume 25, Issue 1, Page 240-251, January 2022., 2022 The resilience of vertebrate populations is declining worldwide. Multiple threats are accelerating this loss of resilience. Abstract Maintaining the resilience of natural populations, their ability to resist and recover from disturbance, is crucial to prevent biodiversity loss.

Limnology and Oceanography Letters, Volume 6, Issue 6, Page 339-347, December 2021., 2021 Establishing the foundations for a sustainable use of deep‐sea resources relies on increasing knowledge on this inaccessible ecosystem, which is challenging with traditional methods. The analysis of environmental DNA (eDNA) emerges as an alternative, but it has been scarcely applied to deep‐sea fish.

Phylogeny and evolutionary history of the amniote egg
Journal of Morphology, Volume 282, Issue 7, Page 1080-1122, July 2021., 2021 We review morphological features of the amniote egg and embryos in a large comparative phylogenetic framework, including all major clades of extant vertebrates. We discuss 40 characters that are relevant for an analysis of the evolutionary history of the vertebrate egg. Special attention is given to the morphology of the cellular yolk sac, the eggshell,

Gene expression, evolution, and the genetics of electrosensing in the smalltooth sawfish, <i>Pristis pectinata</i>. [PDF]
Ecol EvolSawfishes (Pristidae) are large, highly threatened rays named for their tooth‐studded rostrum, which is used for prey sensing and capture. To better understand the genetic underpinnings of these unique animals, we used RNA‐seq data from multiple tissues to annotate a publicly available genome and compared this data to other elasmobranchs.

Some notes on the anterior dorsal fin and venous drainage in Callorhinchus (Holocephali) [PDF]
, 1975 The region of the anterior dorsal fin of the elephant-fish (CalZorhinchus callorhynchus (L.) has been examined by dissection, by injection of radio-opaque material and in serial sections.

Vacchi's palatal organ: a widespread trait in Holocephali
Journal of Fish Biology, 2018 A palatal organ, possibly used for food sorting and processing, has previously been identified among the vomerine toothplates of the chimaeroid Chimaera monstrosa. In this study, the palatal organ was described in six additional species, confirming it is a widespread trait among holocephalans.
