Pelvic spine reduction affects diet but not gill raker morphology in two polymorphic brook stickleback (Culaea inconstans) populations

open access: yesEcology and Evolution, Volume 13, Issue 9, September 2023., 2023
The extent of parallelism might generally be lower in between‐species versus between‐population comparisons. In two populations of brook sticklebacks, we found that diet differences were associated with pelvic spine reduction, but we found no evidence of any difference in gill raker morphology associated with pelvic spine reduction. This is in contrast

The Extremophile Endolithella mcmurdoensis gen. et sp. nov. (Trebouxiophyceae, Chlorellaceae), A New Chlorella‐like Endolithic Alga From Antarctica [PDF]

open access: greenJournal of Phycology, 2019
The McMurdo Dry Valleys constitute the largest ice‐free region of Antarctica and one of the most extreme deserts on Earth. Despite the low temperatures, dry and poor soils and katabatic winds, some microbes are able to take advantage of endolithic microenvironments, inhabiting the pore spaces of soil and constituting photosynthesis‐based communities ...

Comparative study of algal community in African sharptooth catfish (Clarias gariepinus, Burchell 1822) and Nile tilapia (Oreochromis niloticus, Linnaeus 1758) farming ponds

open access: yesAquaculture, Fish and Fisheries, Volume 3, Issue 2, Page 149-164, April 2023., 2023
In the fish farming station, algae specific richness varies according to the water collection point (rearing pond, evacuation canal and decantation pond). Algae contribute differentially to fish diets: biomass is mostly used by Nile Tilapia (herbivorous) than African catfish (omnivorous).

Bioinformatic analysis and relative expression of hyd and fdx during H2 production in microalgae

open access: yesPhycological Research, Volume 71, Issue 1, Page 37-55, January 2023., 2023
SUMMARY Microalgae have been positioned as excellent models for producing new sources of energy (biofuels and biohydrogen). Some investigations in these biological models have been directed to know if the enzymes ferredoxin (FDX) and hydrogenase (HYD) are involved in the algae producing different concentrations of molecular hydrogen (H2).

Microbial community associated with the crustose lichen Rhizocarpon geographicum L. (DC.) living on oceanic seashore: A large source of diversity revealed by using multiple isolation methods

open access: yesEnvironmental Microbiology Reports, Volume 14, Issue 6, Page 856-872, December 2022., 2022
Abstract Recently, the study of the interactions within a microcosm between hosts and their associated microbial communities drew an unprecedented interest arising from the holobiont concept. Lichens, a symbiotic association between a fungus and an alga, are redefined as complex ecosystems considering the tremendous array of associated microorganisms ...

White spot syndrome virus host range and impact on transmission

open access: yesReviews in Aquaculture, Volume 14, Issue 4, Page 1843-1860, September 2022., 2022
Abstract White spot syndrome virus (WSSV), the etiological agent of white spot disease (WSD), is a significant pathogen affecting shrimp farming industry worldwide. White spot syndrome virus is a generalist virus mainly infecting decapod crustaceans. The aims of this review were to: (1) Re‐evaluate and update the status of reported WSSV host and vector
