The timing of Timezyme diversification in vertebrates. [PDF]
PLoS ONE, 2014 All biological functions in vertebrates are synchronized with daily and seasonal changes in the environment by the time keeping hormone melatonin. Its nocturnal surge is primarily due to the rhythmic activity of the arylalkylamine N-acetyl transferase ...

Brain Reconstruction Across the Fish-Tetrapod Transition; Insights From Modern Amphibians
Frontiers in Ecology and Evolution, 2021 The fish-tetrapod transition (which incorporates the related fin-limb and water-land transitions) is celebrated as one of the most important junctions in vertebrate evolution.

Mandibular musculature constrains brain–endocast disparity between sarcopterygians
Royal Society Open Science, 2020 The transition from water to land by the earliest tetrapods in the Devonian Period is seen as one of the greatest steps in evolution. However, little is understood concerning changes in brain morphology over this transition.

Prioritizing the reassessment of data‐deficient species on the IUCN Red List
Conservation Biology, Volume 37, Issue 6, December 2023., 2023 Abstract Despite being central to the implementation of conservation policies, the usefulness of the International Union for Conservation of Nature (IUCN) Red List of Threatened Species is hampered by the 14% of species classified as data‐deficient (DD) because information to evaluate these species’ extinction risk was lacking when they were last ...

Non-Coding RNA, 2019 The conservation of intronic sequences was studied in the mitochondrial solute carrier (SLC25A*) genes of Zebrafish, Chicken, Mouse and Human. These genes are homologous and the coding sequences have been well conserved throughout Vertebrates, but the ...

The cranial endocast of the Upper Devonian dipnoan ‘Chirodipterus’ australis [PDF]
PeerJ, 2018 One of the first endocasts of a dipnoan (lungfish) to be realised was that of the Upper Devonian taxon Chirodipterus australis. This early interpretation was based on observations of the shape of the cranial cavity alone and was not based on a natural ...

The first Jurassic coelacanth from Switzerland
Swiss Journal of Palaeontology, 2022 Coelacanths form a clade of sarcopterygian fish represented today by a single genus, Latimeria. The fossil record of the group, which dates back to the Early Devonian, is sparse.
