Global meta‐analysis reveals the drivers of gut microbiome variation across vertebrates

iMetaOmics, Volume 1, Issue 2, December 2024.
This study analyzed 6508 16S rRNA gene sequence data from 113 vertebrate species worldwide and evaluated the effects of host diet and habitat climate on the diversity of the vertebrate gut microbiome. The results showed that diet and climate factors significantly affected changes in the gut microbiome.

Reconstructing the muscular ground pattern of phylactolaemate bryozoans: first data from gelatinous representatives

BMC Evolutionary Biology, 2017
Background Phylactolaemata is commonly regarded the earliest branch within Bryozoa and thus the sister group to the other bryozoan taxa, Cyclostomata and Gymnolaemata. Therefore, the taxon is important for the reconstruction of the bryozoan morphological

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.

High levels of species' extirpation in an urban environment—A case study from Berlin, Germany, covering 1700–2023

Ecology and Evolution, Volume 14, Issue 7, July 2024.
Our study compiled and analysed spatio‐temporal species' extirpation on a broad taxonomic coverage at the city scale. We revealed high number of extirpations, which are in the twenty‐firstcentury already comparable with previous centuries, and showed that cities might be suitable systems for studying species' extirpation processes due to their small ...

Structural basis of neuropeptide Y signaling through Y1 and Y2 receptors

MedComm, Volume 5, Issue 7, July 2024.
Neuropeptide Y (NPY) serves a critical role in modulating a variety of physiological processes. Gaining comprehensive understanding of structural mechanisms through which Y1R and Y2R interact with NPY is indispensable for the rational design of selective drugs.

Retention of fatty acyl desaturase 1 (fads1) in Elopomorpha and Cyclostomata provides novel insights into the evolution of long-chain polyunsaturated fatty acid biosynthesis in vertebrates

BMC Evolutionary Biology, 2018
Background Provision of long-chain polyunsaturated fatty acids (LC-PUFA) in vertebrates occurs through the diet or via endogenous production from C18 precursors through consecutive elongations and desaturations.

Darwin, Haeckel, and the “Mikluskan gas organ theory”

Developmental Dynamics, Volume 253, Issue 4, Page 370-389, April 2024.
Abstract A previously unknown reference to the Russian ethnologist, biologist, and traveler Nikolai N. Miklucho‐Maclay (1846–1888) was discovered in correspondence between Charles Darwin (1809–1882) and Ernst Haeckel (1834–1919). This reference has remained unknown to science, even to Miklucho‐Maclay's biographers, probably because Darwin used the ...

The mitogenome of the southern Brook Lamprey,Ichthyomyzon gagei(Cyclostomata: Petromyzontidae) [PDF]

Mitochondrial DNA Part B, 2016
The southern brook lamprey (Ichthyomyzon gagei) is a non-parasitic lamprey endemic to the southeastern US. Here, we report the complete mitogenome of this basal vertebrate and found its genomic organization to be similar to that of other reported lamprey mitogenomes.

Modelling spatial distributions of biogenic habitat‐forming taxa to inform marine spatial planning

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 34, Issue 3, March 2024.
Abstract Biogenic habitats are foundational habitats for species assemblages and drive a range of ecosystem functions. The Hauraki Gulf/Tiikapa Moana is the most intensively used coastal area in Aotearoa/New Zealand, and decades of commercial fishing, sedimentation and industrialization have degraded biogenic habitats in the Gulf.

Morphology of ctenostome bryozoans: 7. Hislopia, Echinella and Timwoodiellina

Journal of Morphology, Volume 285, Issue 2, February 2024.
Schematic drawings of hislopiids ctenostomes showing major polypide features. Abstract Ctenostome bryozoans are a small group of gymnolaemates comprising less than 400 recent species. They are paraphyletic and ctenostome‐grade ancestors gave rise to Cheilostomata, the most dominant and speciose taxon of Bryozoa in the present day.
