This study evaluated the anti-inflammatory and antioxidant effects of a methanolic extract of Byrsonima intermedia leaves (EBi) in a rat model of 2,4,6-trinitrobenzene sulfonic acid (TNBS)-induced colitis. Male Wistar rats received intracolonic TNBS for lesion induction and relapse, followed by oral treatment with EBi for seven days. EBi markedly reduced the severity of colonic injury, as demonstrated by a 63% decrease in macr...
Earth's biodiversity is central to ecosystem health and resilience, providing essential functions and services. The Red Sea is a recognised marine biodiversity hotspot with high endemism and unique environmental conditions that support extensive but poorly resolved biodiversity. Here, we applied metagenomic analyses to sediment samples collected from coastal to deep‐sea environments during the Red Sea Decade Expedition 2022 to...
First spawning record of the widespread Indo-Pacific Pavona maldivensis observed in the Red SeaOA Marine
Information on coral reproductive biology and coral spawning times is crucial to advance basic and applied research and inform strategies for coral reef conservation and restoration. Important efforts have been made to collate coral spawning times and reproductive patterns in global and regional datasets. Here, we report and document the first in situ spawning of Pavona maldivensis Gardiner, 1905, observed in the Red Sea. A me...
Turmeric products: Evaluation of curcumin and trace elementsNARA Subscribed
Sexual reproduction is a crucial process for reef building coral populations to maximize genetic diversity and recover from large scale disturbances. Mass spawning events by Acropora species represent critical opportunities for populations to persist, and a process that is increasingly exploited to actively restore degraded reefs. However, the timing and predictive capacity of coral spawning throughout the broad thermal and en...
Evidence of hawksbill turtle (Eretmochelys imbricata) depredation on fish caught in gillnetsOA Marine
Bycatch is a major global threat to marine megafauna and occurs in nearly all fishing fleets, including small-scale fisheries that use gillnets. Gillnets represent a threat to endangered air-breathing megafauna, who incidentally entangle in bottom-set gillnets and suffocate after being attracted by bait that is secured on fishing gear. We here provide the first evidence that hawksbill turtles feed on trapped fish in gillnets,...
Threats leading to a reduction in coral populations are apparent worldwide. Several different approaches have been tested to accelerate the adaptation of corals to a changing climate. Here, we evaluated the skeleton structure, crystal habit, and chemical changes of the coral Pocillopora damicornis in response to the pathogen ( Vibrio coralliilyticus ) and probiotic (Beneficial Microorganisms for Corals, BMCs) inoculation under...
Climate change is turning formerly pristine ecosystems into ever-changing states, causing major disturbance and biodiversity loss. Such impacted marine ecosystems and organisms exhibit clear microbiome shifts that alter their function. Microbiome-targeted interventions appear as feasible tools to support organismal and ecosystem resilience and recovery by restoring symbiotic interactions and thwarting dysbiotic processes. Howe...
NEOTROPICAL FRESHWATER FISHES : A dataset of occurrence and abundance of freshwater fishes in the NeotropicsNARA Subscribed
The Neotropical region hosts 4225 freshwater fish species, ranking first among the world's most diverse regions for freshwater fishes. Our NEOTROPICAL FRESHWATER FISHES data set is the first to produce a large‐scale Neotropical freshwater fish inventory, covering the entire Neotropical region from Mexico and the Caribbean in the north to the southern limits in Argentina, Paraguay, Chile, and Uruguay. We compiled 185,787 distri...
Coral research is being ushered into the genomic era. To fully capitalize on the potential discoveries from this genomic revolution, the rapidly increasing number of high-quality genomes requires effective pairing with rigorous taxonomic characterizations of specimens and the contextualization of their ecological relevance. However, to date there is no formal framework that genomicists, taxonomists, and coral scientists can co...
