METAMORPHOSIS AND IDENTITY CONSTRUCTION IN SALMAN RUSHDIE’S THE SATANIC VERSE [PDF]

open access: yesUniversity of Bucharest Review. Literary and Cultural Studies Series, 2022

Divergent nucleic acid allocation in juvenile insects of different metamorphosis modes

open access: yesScientific Reports, 2021
Nucleic acids help clarify variation in species richness of insects having different metamorphosis modes, a biological conundrum. Here we analyse nucleic acid contents of 639 specimens of aquatic insects collected from four high mountain streams of ...

Tadpole growth rates and gut bacterial community: Dominance of developmental stages over temperature variations.

open access: yesPLoS ONE, 2023
Tadpoles present an intriguing model system for studying the regulation and selection of gut microbiota. They offer a unique perspective to enhance our understanding of host-microbiota interactions, given their capacity to alter the dynamics of the gut ...

Large Igneous Province Record Through Time and Implications for Secular Environmental Changes and Geological Time‐Scale Boundaries

open access: yesGeophysical Monograph Series, Page 1-26., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Differential effects of 3,5-T2 and T3 on the gill regeneration and metamorphosis of the Ambystoma mexicanum (axolotl)

open access: yesFrontiers in Endocrinology, 2023
Thyroid hormones (THs) regulate tissue remodeling processes during early- and post-embryonic stages in vertebrates. The Mexican axolotl (Ambystoma mexicanum) is a neotenic species that has lost the ability to undergo metamorphosis; however, it can be ...

Gut microbial ecology of Xenopus tadpoles across life stages

open access: yesPeer Community Journal, 2021
Background: The microorganism world living in amphibians is still largely under-represented and under-studied in the literature. Among anuran amphibians, African clawed frogs of the Xenopus genus stand as well-characterized models with an in-depth ...
