Environmental Tipping Points for Sperm Motility, Fertilization, and Embryonic Development in the Crown-of-Thorns Starfish

open access: yesDiversity, 2017
For broadcast spawning invertebrates such as the crown-of-thorns starfish, early life history stages (from spawning to settlement) may be exposed to a wide range of environmental conditions, and could have a major bearing on reproductive success and ...

A Biomimetic Starfish‐Inspired Magnetic Soft Robot with Ultrasound Monitoring for Targeted Inflammatory Bowel Disease Therapy

open access: yesAdvanced Sensor Research, Volume 5, Issue 8, August 2026.
This work introduces a starfish‐inspired magnetic soft robot for localized, long‐term inflammatory bowel disease therapy. Featuring biomimetic multi‐arm microspines and magnetic actuation, it navigates the gastrointestinal tract, adheres firmly, and releases drugs on demand, monitored by ultrasound, with validated biosafety and ex vivo therapeutic ...

Reconsidering the role of introduced species in the climate‐affected and highly invaded eastern Mediterranean

open access: yesConservation Biology, Volume 40, Issue 4, August 2026.
Abstract Bioinvasions are considered mostly as a biodiversity and conservation hazard, but in specific situations, introduced species can bring ecological or socioeconomic benefits. We assessed the social–ecological role of marine introduced species in the eastern Mediterranean Sea—a global hotspot of bioinvasions and extirpations—and their potential ...

Predicting Coral Cover Trends From Local to Broad Spatial Scales

open access: yesGlobal Change Biology, Volume 32, Issue 8, August 2026.
We present an integrated framework to track coral cover trends across multiple spatial scales, ranging from a local scale of 5 km2 to a broad scale exceeding 5000 km2. Through use cases, we demonstrate the value of our spatio‐temporal prediction framework in generating new insights from monitoring data across varying spatial and temporal data ...

Corals and Reef‐Dwelling Fish Regulate Carbon Storage and Cycling Processes in Coral Reef Ecosystems

open access: yesAdvanced Science, Volume 13, Issue 41, 22 July 2026.
Coral reefs are biodiversity hotspots, yet their role in carbon storage and cycling remains poorly understood. Using field surveys and modeling in the South China Sea, we reveal the overlooked potential of carbon storage in reef ecosystems and how reef fish, corals, and surface sediment jointly shape reef carbon reservoirs.

State of the Reef Report 2004: Crown-of-thorns starfish [PDF]

open access: yes, 2004
The crown-of-thorns starfish is one of only a few animals that feed on living coral tissue. The starfish is named for the dense covering of long, sharp spines on its upper surface. At low densities the crown-of-thorns starfish is a ‘normal’ part of the

A review of ecological risks of coral reef interventions

open access: yesRestoration Ecology, Volume 34, Issue 5, July 2026.
Abstract Introduction Coral reefs, essential for biodiversity, livelihoods, and global economies, face severe threats from climate change and other stressors. Curbing greenhouse emissions is crucial, but the urgent situation also calls for immediate intervention strategies.

Sex-specific expression of pheromones and other signals in gravid starfish

open access: yesBMC Biology, 2022
Background Many echinoderms form seasonal aggregations prior to spawning. In some fecund species, a spawning event can lead to population outbreaks with detrimental ecosystem impacts.
