Total alkalinity production in a mangrove ecosystem reveals an overlooked Blue Carbon component

open access: yesLimnology and Oceanography Letters, 2021
Mangroves have the capacity to sequester organic carbon (Corg) in their sediments permanently. However, the carbon budget of mangroves is also affected by the total alkalinity (TA) budget.

Management and research efforts are failing dolphins, porpoises, and other toothed whales

open access: yesScientific Reports
Despite being subject to intensive research and public interest many populations of dolphins, porpoises, and other toothed whales (small cetaceans) continue to decline, and several species are on the verge of extinction. We examine small cetacean status,

Assessing Magnesium Chloride as a Chemical for Immobilization of a Symbiotic Jellyfish (Cassiopea sp.)

open access: yesFrontiers in Marine Science, 2022
Immobilization of marine invertebrates for research purposes has been commonly used and is often necessary to obtain high-quality findings. Despite these approaches being standard procedures, they can affect the specimens, and their responses as well ...

Habitat suitability models reveal extensive distribution of deep warm-water coral frameworks in the Red Sea

open access: yesCommunications Earth & Environment
Deep-sea coral frameworks are understudied in the Red Sea, where conditions in the deep are conspicuously warm and saline compared to other basins. Habitat suitability models can be used to predict the distribution pattern of species or assemblages where

Probiotics reshape the coral microbiome in situ without detectable off-target effects in the surrounding environment

open access: yesCommunications Biology
Beneficial microorganisms for corals (BMCs), or probiotics, can enhance coral resilience against stressors in laboratory trials. However, the ability of probiotics to restructure the coral microbiome in situ is yet to be determined.

Influence of Technology on Public Administration: Opportunities and Challenges

open access: yesJournal of Current Social and Political Issues
This study examines the impact of technology on public administration, emphasising both its transformative opportunities and the challenges it presents. In the context of increasing digitisation, the research explores how innovations such as e-governance,

Coral reef carbonate budgets and ecological drivers in the central Red Sea – a naturally high temperature and high total alkalinity environment [PDF]

open access: yesBiogeosciences, 2018
The structural framework provided by corals is crucial for reef ecosystem function and services, but high seawater temperatures can be detrimental to the calcification capacity of reef-building organisms. The Red Sea is very warm, but total alkalinity

Cross shelf benthic biodiversity patterns in the Southern Red Sea

open access: yesScientific Reports, 2017
The diversity of coral reef and soft sediment ecosystems in the Red Sea has to date received limited scientific attention. This study investigates changes in the community composition of both reef and macrobenthic communities along a cross shelf gradient.

Nitrogen fixation and denitrification activity differ between coral- and algae-dominated Red Sea reefs

open access: yesScientific Reports, 2021
Coral reefs experience phase shifts from coral- to algae-dominated benthic communities, which could affect the interplay between processes introducing and removing bioavailable nitrogen.
