Feeding Behavior of Coralliophila sp. on Corals Affected by Caribbean Ciliate Infection (CCI): A New Possible Vector?
(
MDPI
, 2022 , Article)
Coral reefs in the Caribbean are known to be affected by many coral diseases, yet the ecology and etiology of most diseases remain understudied. The Caribbean ciliate infection (CCI) caused by ciliates belonging to the ...
Evidencing the role of carbonic anhydrase in the formation of carbonate minerals by bacterial strains isolated from extreme environments in Qatar
(
Elsevier
, 2022 , Article)
Calcium carbonate, one of the most abundant minerals in the geological records is considered as primary source of the carbon reservoir. The role of microorganisms in the biotic precipitation of calcium carbonate has been ...
Study of bacterial interactions in reconstituted hydrocarbon-degrading bacterial consortia from a local collection, for the bioremediation of weathered oily-soils
(
Elsevier B.V.
, 2021 , Article)
To enhance the process of bacterial remediation of weathered hydrocarbons, the area of Dukhan, Qatar, was considered as a model for weathering processes. Self-purification by indigenous hydrocarbon-degrading bacteria showed ...
Coral reef resilience differs among islands within the Gulf of Mannar, southeast India, following successive coral bleaching events
(
Springer Science and Business Media Deutschland GmbH
, 2021 , Article)
We used a 12-yr data set of benthic cover (2005�2017), spanning two bleaching events, to assess changes in benthic cover and coral community composition along 21 islands within Gulf of Mannar (GoM), southeast India. Overall, ...
Emergent community architecture despite distinct diversity in the global whale shark (Rhincodon typus) epidermal microbiome
(
Nature Research
, 2023 , Article)
Microbiomes confer beneficial physiological traits to their host, but microbial diversity is inherently variable, challenging the relationship between microbes and their contribution to host health. Here, we compare the ...
Diversity, concentration and dynamics of culturable fungal bioaerosols at doha, qatar
(
MDPI AG
, 2021 , Article)
This research was conducted to investigate the dynamics of airborne fungi using viable culture collection and in respect to different abiotic variables, including seasonal and intra-diurnal variations. A gravimetric method ...
Widespread diversity deficits of coral reef sharks and rays
(
American Association for the Advancement of Science
, 2023 , Article)
A global survey of coral reefs reveals that overfishing is driving resident shark species toward extinction, causing diversity deficits in reef elasmobranch (shark and ray) assemblages. Our species-level analysis revealed ...
Acute and chronic toxicity assessments of 17β-estradiol (E2) and 17α-ethinylestradiol (EE2) on the calanoid copepod Acartia clausi: Effects on survival, development, sex-ratio and reproduction
(
Elsevier B.V.
, 2022 , Article)
Estrogens, such as the 17β-estradiol (E2) and the 17α-ethinylestradiol (EE2), have been regarded as a global threat to aquatic ecosystems due to their pseudo-persistence, their high estrogenic activity and their toxicity ...
Zooplankton abundance and community structure driven by tidal currents in a Mediterranean coastal lagoon (Boughrara, Tunisia, SW Mediterranean Sea)
(
Academic Press
, 2021 , Article)
Lagoons and coastal marine zones are very productive and useful ecosystems, but they are threatened by the effects of global change and anthropogenic pressures. These effects have a negative impact on the zooplankton, ...
Unfolding jellyfish bloom dynamics along the mediterranean basin by transnational citizen science initiatives
(
MDPI AG
, 2021 , Article)
Science is addressing global societal challenges, and due to limitations in research financing, scientists are turning to the public at large to jointly tackle specific environmental issues. Citizens are therefore increasingly ...
