High Early Embryo Mortality and Low Hatching Success Observed in Aldabra Giant Tortoise Populations

open access: yesEcology and Evolution, Volume 16, Issue 7, July 2026.
This preliminary study provides the first population‐level assessment of fertilisation and hatching success in the Aldabra giant tortoise across natural and translocated populations in Seychelles, revealing low and highly variable hatching success—particularly in translocated populations.

Stress Attenuation and Energy Absorption of the Coral Sand with Different Particle Sizes under Impacts

open access: yes, 2018
The stress wave attenuation and energy absorption in the coral sand were respectively investigated. A series of experiments were carried out by using a new methodology with an improved split Hopkinson pressure bar (SHPB).

Size and Ecology of a Giant Pavona clavus Coral Colony in the Kingdom of Tonga

open access: yesEcology and Evolution, Volume 16, Issue 7, July 2026.
Some individual coral colonies can grow to immense sizes and survive for centuries, offering rare insight into how corals persist over long time scales. This study documents one of the largest coral colonies ever recorded—a colossal Pavona clavus in Tonga—and shows that, despite being dominated by a single species, it supports fish communities and ...

Conversion of coral sand to calcium phosphate for biomedical applications

open access: yes, 2007
Coral sand grains were analyzed using simultaneous differential thermogravimetric analysis (DTA/TGA), Fourier-Transform infrared spectroscopy (FTIR), x-ray diffraction (XRD), and environmental scanning electron microscopy (ESEM).

Abundant interactions and feedbacks between aquatic deoxygenation and the other planetary boundaries suggest “unsafe” levels of oxygen loss with far‐reaching impacts

open access: yesLimnology and Oceanography, Volume 71, Issue 7, July 2026.
Abstract Oxygen is critical for nearly all life on Earth, including aquatic species that breathe dissolved oxygen in both freshwater and marine systems. The rapid, global, and anthropogenic loss of dissolved oxygen known as “aquatic deoxygenation” threatens life in these environments, the human communities that depend on them, and Earth system ...

Lichen bleaching as a response to long‐term experimental warming in the High Arctic

open access: yesFunctional Ecology, Volume 40, Issue 7, Page 2318-2331, July 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Lichens are an important component of Arctic ecosystems. Studies have indicated a decline in the abundance of Arctic lichens during recent decades, which is often attributed to competitive pressure from vascular plants.

An Experimental Study on the Seismic Response of Vertical and Batter Pile Foundations at Coral Sand Sites

open access: yesJournal of Marine Science and Engineering
Liquefaction and earthquake damage to coral sand sites can cause engineering structure failure. Both testing and analyzing the seismic response characteristics of pile groups on coral sand sites are highly important for the seismic design of engineering ...

Social organization and habitat use shape the gut microbiome of a marine fish

open access: yesJournal of Animal Ecology, Volume 95, Issue 7, Page 1091-1107, July 2026.
This study provides the first evidence linking habitat use—and to a lesser extent social organization—to gut microbiome composition in a wild marine fish. The results indicate that local habitat conditions are the primary driver of microbial variation, while social effects are detectable but weak.
