On the type material of Lepidosiren paradoxa Fitzinger, 1837 (Sarcopterygii, Dipnoi)

Comptes Rendus. Biologies, 2010
Lepidosiren paradoxa , the first living dipnoan to be discovered, was first described from two specimens collected by Johann Natterer during his 18-year expedition in Brazil. Those specimens were first studied by Fitzinger and Bischoff, but few data are available to identify the syntypes of L.

Deep‐soil sampling in Chile reveals a new elateroid beetle family, Badmaateridae fam. nov. (Coleoptera)

Systematic Entomology, Volume 51, Issue 1, January‐March 2026.
Genomic data support the definition of a new elateroid family, Badmaateridae fam. nov., with Badmaater chilensis gen. nov. sp. nov. as the only representative. Badmaateridae is sister to an extensive clade containing fireflies, soldier beetles, net‐winged beetles and click beetles.

Uncovering a 500 million year old history and evidence of pseudogenization for TLR15

Frontiers in Immunology, 2022
IntroductionToll like receptors (TLRs) are at the front line of pathogen recognition and host immune response. Many TLR genes have been described to date with some being found across metazoans while others are restricted to specific lineages.

FishSounds Versions 2 and 3: Achieving the Largest Global Database of Fish Sound Production

Global Ecology and Biogeography, Volume 34, Issue 11, November 2025.
ABSTRACT Motivation Fish sounds are integral to a variety of ecological functions, including reproduction, predator–prey interactions and recruitment, with ever‐growing interest in their relationships to anthropogenic impacts and applications for passive acoustic monitoring.

Structural and functional divergence of growth hormone-releasing hormone receptors in early sarcopterygians: lungfish and Xenopus. [PDF]

PLoS ONE, 2013
The evolutionary trajectories of growth hormone-releasing hormone (GHRH) receptor remain enigmatic since the discovery of physiologically functional GHRH-GHRH receptor (GHRHR) in non-mammalian vertebrates in 2007.

Fish species lifespan prediction from promoter cytosine‐phosphate‐guanine density

Molecular Ecology Resources, Volume 25, Issue 5, July 2025.
Abstract Lifespan is a key attribute of a species' life cycle and varies extensively among major lineages of animals. In fish, lifespan varies by several orders of magnitude, with reported values ranging from less than 1 year to approximately 400 years.

The giant cretaceous Coelacanth (Actinistia, Sarcopterygii) Megalocoelacanthus dobiei Schwimmer, Stewart & Williams, 1994, and its bearing on Latimerioidei interrelationships. [PDF]

PLoS ONE, 2012
We present a redescription of Megalocoelacanthus dobiei, a giant fossil coelacanth from Upper Cretaceous strata of North America. Megalocoelacanthus has been previously described on the basis of composite material that consisted of isolated elements ...

Habitat of early stegocephalians (Chordata, Vertebrata, Sarcopterygii): a little saltier than most paleontologists like? [PDF]

Fossil Record
A controversy on the degree of marine influence in the paleoenvironments represented by many Paleozoic stegocephalian-bearing fossiliferous localities has persisted for decades.

Developmental sequence of the chondrocranium in the obligate carnivorous larvae of Lepidobatrachus laevis (Amphibia: Ceratophryidae)

The Anatomical Record, Volume 308, Issue 1, Page 26-44, January 2025.
Abstract The vertebrate head and its skull represent a significant innovation that has played a key role in the evolutionary and ecological success of vertebrates. For a global and integral understanding of the evolution of the head skeleton, it is essential to have reliable information on the development of chondrocranium in a wide range of vertebrate

The relationship between the secondary vascular system and the lymphatic vascular system in fish

Biological Reviews, Volume 99, Issue 6, Page 2108-2133, December 2024.
ABSTRACT New technologies have resulted in a better understanding of blood and lymphatic vascular heterogeneity at the cellular and molecular levels. However, we still need to learn more about the heterogeneity of the cardiovascular and lymphatic systems among different species at the anatomical and functional levels.
