RIYADH: The Red Sea’s rich marine life depends on maintaining a balanced environment to protect biodiversity and delicate habitats, with the survival of each species closely tied to the health of its surroundings.
This interdependence prompted a Saudi researcher to explore the critical role of algae in shifting ecosystems and investigate the impact of nighttime hypoxia on macroalgae and crustose algae, especially during the hot summer months.
Taiba Alamoudi, a Saudi PhD candidate in marine science at King Abdullah University of Science and Technology, and her colleagues examined how algae play a vital role in coral reef ecosystems, contributing to nutrient cycling and stability.
However, climate change has been linked to ocean warming and deoxygenation, causing greater stratification and reduced oxygen solubility, which ultimately harm algal health.
Alamoudi told Arab News that the inspiration for her research, titled “Impacts of Climate Change and the Biotechnological Potential of Seaweed,” was “the phase shifts occurring in coral reef ecosystems, where algae begin to dominate areas once rich with corals.”
She said: “While it might seem that algae have an advantage over corals in warmer oceans, I believe the situation is more complicated. Algae, like corals, are also impacted by environmental stressors such as nighttime hypoxia, a drop in oxygen levels after sunset when photosynthesis ceases but respiration continues.”
Alamoudi’s research seeks to “explore what a balanced ecosystem should look like amid climate change” and deepen understanding of the vulnerabilities and strengths of both corals and algae.
This insight, she said, provides a deeper understanding of reef ecosystem dynamics and supports the development of more effective strategies to preserve their balance and health for the future.
The two main criteria for the studied species were their association with reefs and the limited research on them in the Red Sea region.
“Specifically, we placed special emphasis on crustose coralline algae due to their critical role in reef-building and maintenance,” Alamoudi said.
“These algae deposit calcium carbonate in their cell walls, effectively acting as natural cement that strengthens reef structures and provides essential substrates for coral larvae to settle and grow.”
The researchers used “gas buffering” methods to simulate natural reef oxygen dynamics and replicate nighttime hypoxia.
“By bubbling the seawater stock with the specific concentrations of oxygen, carbon dioxide, and nitrogen gases, we can adjust the dissolved oxygen and pH levels in our setups to the required experimental levels.”
The study also measured metabolic respiration rates, oxygen production, photosynthetic efficiency, and metabolomic processes to assess the impact on algal health and functionality.
In addition, Alamoudi said, “we examine changes in their associated microbial communities and observe visual cues like discoloration or tissue degradation.”
The experiments’ results showed that “macroalgae and crustose algae significantly mitigate the impacts of ocean warming through substantial daytime oxygen production, often leading to oxygen supersaturation that enhances reef resilience.”
However, she said, this benefit is offset at night when photosynthesis stops.
Climate change worsens nighttime hypoxia by raising sea temperatures, which in turn lower oxygen solubility and increase metabolic rates. Warmer water holds less dissolved oxygen, reducing its overall availability.
“Elevated temperatures increase the metabolic demands of the entire reef community, intensifying oxygen consumption and leading to nighttime hypoxia,” Alamoudi said.
“This hypoxic stress disrupts the algae’s physiological processes and associated reef microbial communities, making them more vulnerable to additional stressors.”
She added: “While they help maintain current reef conditions, prolonged nighttime hypoxia compromises their ability to support reef expansion and long-term ecosystem vitality.
“Understanding the balance between their daytime benefits and nighttime vulnerabilities is crucial for defining a truly balanced ecosystem.”
During the day, photosynthesis by algae produces oxygen that helps offset increased consumption. “However, at night, no new oxygen is produced while organisms continue to consume it at elevated rates,” said Alamoudi.
“This combination of decreased oxygen solubility, increased metabolic demand, and reduced oxygen production exacerbates nighttime hypoxia, making it a significant stressor intensified by climate change.”
During peak summer temperatures, the research team observed that hypoxia worsens.
“Warmer water reduces oxygen solubility and increases the metabolic rates of the reef community, leading to greater oxygen consumption,” Alamoudi said. “At night, without photosynthesis to produce oxygen, this intensifies hypoxia.
“Consequently, marine organisms experience increased stress during the hottest months, making them more vulnerable to hypoxic conditions compared to cooler seasons.”
Moreover, Alamoudi’s research shows how changes in the health of macroalgae and crustose algae can have cascading effects on marine organisms, particularly herbivorous species and invertebrates, potentially impacting their population.
“Coralline algae are crucial for coral larval settlement. Their decline could hinder coral recruitment and reef regeneration,” she said. “This, in turn, affects species dependent on healthy coral reefs for habitat, potentially reducing biodiversity and altering the ecosystem’s balance.”
By studying the impact of nighttime hypoxia on algae, Alamoudi aims to uncover their true role in these shifting ecosystems.
She said her research helps scientists “explore what a balanced ecosystem should look like amid climate change,” noting that “understanding the vulnerabilities and advantages of both corals and algae allows us to better comprehend the dynamics of reef ecosystems and develop more effective strategies to preserve their balance and health for the future.”
One of the biggest challenges Alamoudi and her colleagues faced in this research was the need for continuous monitoring, as even slight fluctuations can greatly impact dissolved oxygen and pH levels.
She added that “collecting samples from deeper ocean zones demanded substantial technological resources.” However, her team’s collaboration with the Saudi National Center for Wildlife enabled them to “access these depths and gather the necessary data and specimens.”
Alamoudi said she found it interesting how mesophotic coralline algae, which live in deeper, lower-light reef zones, respond differently from shallow-water species.
“Even short-term hypoxic stress at the microscale can have substantial impacts, potentially leading to significant ecological consequences that are not yet widely studied,” she said.
“This highlights the importance of examining subtle environmental stressors across different habitats, as they may reveal vulnerabilities in marine ecosystems that could affect overall reef health and resilience.”
Alamoudi is one of six winners of the 2024 L’Oreal-UNESCO For Women in Science Program. Currently a PhD student under the mentorship of Ibn Sina Distinguished Professor Carlos Duarte, she earned her undergraduate degree in marine biology from Oregon State University in 2018.
She gained experience in environmental consulting and aquaculture in the Kingdom before joining KAUST in 2020.

“Riyadh is hosting big events and has become a hub. So, we felt this year that we needed to highlight Riyadh, especially at the beginning of the ’80s and ’90s.”
Additionally, the event includes an art book fair featuring a number of international, regional, and local publishers to celebrate the rich and diverse Arab art culture; and an extended art and design market with 92 artists and entities at which the local community can engage, sell, and commission unique works.
“We designed it in a way that anyone walking by the market can see everything. And there is a diversity between painting, photography, sculpting projects, and even design,” Al-Suhaibani said.
The educational program and mentorship sessions are also part of the institute’s strategy to educate, enable, and encourage new generations of artists.
The art fair space is bigger this year, and features works from 11 Saudi-based galleries including Hewar Art, Mono, Hafez, WRD Art, ATHR, and Dawi.
Al-Suhaibani added: “We believe today the market desires to have galleries more specialized to support artists and to showcase their artwork.”
The Misk Art Week mural is also a feature and an interactive space crafted to showcase the creativity of young talents. As children contribute unique visions that are then displayed on a wall, they collectively shape a masterpiece that evolves with each individual contribution. With the help of augmented reality tech, the artwork comes to life in an entirely new dimension.
Misk Art Institute’s goal is to create a cohesive environment in which all artists, regardless of their background, can thrive.
Saudi director Hassan El-Hejaili on filming with kids — and eggs
“In most Saudi films, kids are wise beyond their years,” El-Hejaili explained

ALULA: Saudi filmmaker Hassan El-Hejaili offers a quirky, nostalgic portrayal of childhood mischief in his seven-minute short, “The Extraordinary Misadventures of the Amazing Boy Super-Blurry,” now screening at Jeddah’s Red Sea International Film Festival.
The story follows a bored young Saudi, Zezo, who discovers that he can put his hand into boiling tea without being hurt.
“Tea is part of our culture … we drink it so much that it’s like it’s in our veins,” El-Hejaili told Arab News while sipping a cup of tea, explaining why he chose to begin the story with the beverage.
FASTFACTS
• Hassan El-Hejaili’s short film follows a bored young Saudi, Zezo, who discovers that he can put his hand into boiling tea without being hurt.
• Filmed in black and white — aside from a saturated red tint in the tea — the aesthetic, which has shadows and different gradients, pays homage to classic cinema.
The audience is invited along on Zezo’s adventures — or misadventures — with his siblings as the situation in their dysfunctional home escalates and his superpowers become even more impressive.

“I consider myself a cinema-lover,” said El-Hejaili, who has written multiple books on cinema in Arabic, adding that he drew inspiration from vintage filmmakers such as Georges Melies, who died in 1938.
El-Hejaili chose a kitchen and bathroom as the primary settings, spaces not often seen in Saudi films.
“Those rooms are the heart of the home,” he said, “but every time the family in the film gathers there, something goes wrong.” The film’s tight quarters create a sense of closeness and chaotic spontaneity, capturing playful sibling rivalries, while the distracted parents are too absorbed in their smartphones to notice.
The portrayal of children in the film diverges from typical Saudi cinema and doesn’t spoon-feed everything to the audience — El-Hejaili trusts that they will be able to pour their own cups of tea and join in.
“In most Saudi films, kids are wise beyond their years,” El-Hejaili explained. “I wanted them to lie, fight and break stuff — not in a way that destroys the world, but in a cute, real way. Siblings fight. It’s natural.”
One of the most memorable scenes during the two-day shoot was an egg fight sequence. “It was fun to film but a nightmare to clean,” he said, laughing. “This was the first and last experiment and experience filming with kids — and eggs.”
