Marine nematode taxonomy in the DNA age: the present and future of molecular tools to access their biodiversity [PDF]

open access: yes, 2010
Molecular taxonomy is one of the most promising yet challenging fields of biology. Molecular markers such as nuclear and mitochondrial genes are being used in a variety of studies surveying marine nematode taxa.

Characterization of Chitinolytic and Antifungal Activities in Marine-Derived Trichoderma bissettii Strains

open access: yesMycobiology, 2022
Trichoderma fungi have been intensively studied for mycoparasitism, and the latter is closely related to their cell-wall degrading enzymes including chitinase. Here, we studied marine-derived Trichoderma spp., isolated from distinct sources and locations,

Possible Origin of Stagnation and Variability of Earth's Biodiversity

open access: yes, 2014
The magnitude and variability of Earth's biodiversity have puzzled scientists ever since paleontologic fossil databases became available. We identify and study a model of interdependent species where both endogenous and exogenous impacts determine the ...

Biodiversity of Australian marine macroalgae — A progress report [PDF]

open access: yes, 1998
The biodiversity of Australian macroalgae is assessed by reference to species numbers recorded for the various biogeographical and political regions. The figures show a marked disparity between northern and southern Australia, with the former apparently ...

Marine biodiversity characteristics

open access: yesComptes Rendus. Biologies, 2011
Oceans contain the largest living volume of the “blue” planet, inhabited by approximately 235–250,000 described species, all groups included. They only represent some 13% of the known species on the Earth, but the marine biomasses are really huge. Marine phytoplankton alone represents half the production of organic matter on Earth while marine bacteria

Amphioxus adenosine-to-inosine tRNA-editing enzyme that can perform C-to-U and A-to-I deamination of DNA

open access: yesCommunications Biology, 2023
Adenosine-to-inosine tRNA-editing enzyme has been identified for more than two decades, but the study on its DNA editing activity is rather scarce. We show that amphioxus (Branchiostoma japonicum) ADAT2 (BjADAT2) contains the active site ‘HxE-PCxxC’ and ...

Complete mitochondrial genome of Stethojulis Strigiventer (Labriformes, Labridae): mitogenome characterization and phylogenetic analysis

open access: yesMitochondrial DNA. Part B. Resources, 2019
Stethojulis strigiventer is a tropical reef-associated marine fish belonging to the family Labridae. Herein, we report the first sequencing and assembly of the complete mitochondrial genome of S. strigiventer.

A Catalogue of Marine Biodiversity Indicators [PDF]

open access: yesFrontiers in Marine Science, 2016
A Catalogue of Marine Biodiversity Indicators was developed with the aim of providing the basis for assessing the environmental status of the marine ecosystems. Useful for the implementation of the Marine Strategy Framework Directive (MSFD), this catalogue allows the navigation of a database of indicators mostly related to biological diversity, non ...
