A new study has analyzed a rare flooding event in the Maldives in July 2022 and found it could become a far more common occurrence in the future. By 2050, predicted rises in sea levels, coupled with increased extreme weather events, may result in such flooding happening every two to three years.
A new database compiled by researchers at the University of Queensland provides a detailed picture of the frog and freshwater fish species on hundreds of Australian islands. The study found that 536 islands have freshwater habitats, with 102 amphibian species and 95 freshwater fish species recorded.
Research shows that the 2025 Los Angeles wildfires resulted in an estimated 440 excess deaths, while the 2023 Maui wildfires led to immediate increases in suicide and overdose deaths. Higher social support was linked to improved mental health outcomes but did not buffer physiological effects.
The study chronicles 220 extinctions in Macaronesia, with half linked to human arrival and a post-human extinction rate exceeding 12 times higher than pre-human periods. Conservation efforts are crucial to mitigate the extinction crisis in these unique island ecosystems.
A recent genetic study found that populations of the amphidromous goby Luciogobius ryukyuensis are genetically distinguishable, suggesting minimal larval exchange between islands. This highlights the urgent need for conservation efforts to protect vulnerable habitats in island ecosystems.
A research team discovered fossilized teeth and vertebrae in the Dominican Republic, confirming that large, terrestrial predators like sebecids once inhabited the Caribbean. This finding supports the GAARlandia hypothesis, suggesting temporary land bridges allowed animals to travel between South America and the Caribbean.
A study found that microorganisms using the reductive tricarboxylic acid cycle dominate in shallow-water hydrothermal systems. This energy-efficient process enables them to transfer carbon into organic molecules, allowing them to survive in harsh conditions.
Researchers found that a narrow island separating the two species suggests recent speciation or extensive gene flow. The study proposes sexual selection as a key driver of species differentiation.
Researchers found evidence of hunter-gatherers accessing remote islands like Malta thousands of years earlier than previously thought. They discovered stone tools, hearths, and cooked food waste at the Latnija cave site, indicating that these ancient seafarers were capable of sustained journeys across open water.
A new study reveals that hunter-gatherers crossed over 100 km of open water to reach Malta 8,500 yrs ago, 1,000 yrs before the arrival of farmers. The researchers found evidence of stone tools, hearths, cooked food waste, and wild animal remains.
Fiji iguanas are most closely related to North American desert iguanas, with a lineage that split around 30 million years ago. The animals likely colonized the Pacific islands after volcanic activity produced land, and their arrival coincided with the formation of Fiji.
Experts at Flinders University are calling for a new approach to water security on Pacific islands, where rising sea levels threaten local water supplies. Infiltration galleries, which extract fresh groundwater from shallow depths, may provide a solution, but more research is needed on their optimal design and performance.
Researchers studied pumice rafts from the 2021 Fukutoku-Oka-no-Ba eruption in Japan, finding three phases of evolution involving rounding, fragmentation, and biodiversity increase. The study provides valuable information for mitigating the impact of future eruptions on shoreline communities.
Research team finds that heavy Mg isotopic signatures in volcanic rocks can be explained by partial melting of serpentinite-dominated mélanges. The study proposes a novel model involving diapiric rise and melting of these mélanges, which aligns with geochemical characteristics of arc magmas.
The expedition aims to understand how extreme geohazards interact and improve the long-term safety of coastal regions. Researchers use innovative technologies to collect real-time data on earthquakes, ground movements, and volcanic gases.
Research from Washington University in St. Louis found that bird wing shape is a key factor shaping biodiversity patterns on islands worldwide. The study revealed how birds' dispersal abilities influence the number of species found on islands, with low-dispersal birds leading to steep species-area relationships.
