Desert pavements: A hidden key to Earth surface processes

open access: yesEarth Surface Processes and Landforms, Volume 50, Issue 15, December 2025.
Desert pavements are a global phenomenon in arid environments, representing one of the most extensive geomorphological and geoecological features on Earth. To a large extent, they determine the interplay of key processes governing current and past landscape dynamics.

Genomic adaptations to chemosymbiosis in the deep-sea seep-dwelling tubeworm Lamellibrachia luymesi

open access: yesBMC Biology, 2019
Background Symbiotic relationships between microbes and their hosts are widespread and diverse, often providing protection or nutrients, and may be either obligate or facultative.

Shifting microbial communities in acidified seawaters: insights from polychaetes living in the CO2 vent of Ischia, Italy

open access: yesIntegrative Zoology, Volume 20, Issue 6, Page 1278-1293, November 2025.
The microbiome of polychaetes Syllis prolifera and Platynereis massiliensis complex changes in naturally acidified CO2 vents. A slight degree of acidification is associated with relevant changes in the microbial community, stressing the importance of investigations about the possible effects of ocean acidification on key biological and ecological ...

Inclusion of biofloc meal as a mineral source in diets for Penaeus vannamei cultured in oligohaline water

open access: yesAquaculture Reports
Biofloc meal (BM) obtained from whiteleg shrimp culture waste is a nutritious ingredient commonly used for its high protein content. Nevertheless, its elevated ash value could be of interest in oligohaline culture, where dissolved ions in water are ...

BGC‐Argo Floats Reveal Nitrite and Thiosulfate Dynamics in the Oceans With High Spatiotemporal Resolution

open access: yesGlobal Biogeochemical Cycles, Volume 39, Issue 10, October 2025.
Abstract Marine oxygen deficient zones (ODZs) play a major role in the Earth's biogeochemical cycles and are responsible for nitrogen and sulfur removal from the oceans. Microbial‐reducing reaction processes generate nitrite (NO2−) and sulfur compounds as intermediaries that may accumulate in these zones.

Comparative Embryology and Transcriptomics of Asellus infernus, an Isopod Crustacean From Sulfidic Groundwater

open access: yesEvolution &Development, Volume 27, Issue 3, September 2025.
Individuals of Asellus infernus, a sulfidic subterranean population of the Asellus aquaticus species complex from southeastern Romania (left) and surface individuals of A. aquaticus (right). Extreme differences in phenotype are seen comparing the subterranean and surface individuals as adults (top panels) and as embryonic samples (bottom panels ...

Predictive links between microbial communities and biological oxygen utilization in the Arctic Ocean

open access: yesLimnology and Oceanography, Volume 70, Issue 8, Page 2315-2331, August 2025.
Abstract Microbial metabolism influences rates of net community production (NCP), exerting a direct biological control on marine oxygen and carbon fluxes. In the Arctic, it is increasingly important to understand and quantify this process, as ecological and oceanographic conditions shift due to changing climate.

Biofloc Formation Strategy Effects on Halophyte Integration in IMTA with Marine Shrimp and Tilapia

open access: yesAquaculture Journal
The incorporation of aquaponics into saline integrated multitrophic aquaculture (IMTA) systems, employing biofloc technology (BFT), relies on the cultivation of halophytes capable of withstanding the physical–chemical conditions created by the unique ...
