Age and Growth of An Outbreaking Acanthaster cf. solaris Population within the Great Barrier Reef

Diversity, 2017
Despite having been studied for more than 40 years, much about the basic life history of crown-of-thorns starfish (CoTS; Acanthaster spp.) remains poorly understood. Size at age—a key metric of productivity for any animal population—has yet to be clearly

Physiological and transcriptomic responses to starvation in the corallivorous crown-of-thorn starfish

Frontiers in Marine Science, 2022
The outbreak of coral-eating Acanthaster spp., commonly known as the Crown-of-Thorn Starfish (CoTS), contributes to a significant proportion of coral loss in the tropical Indo-Pacific region.

From Explicit CoT to Implicit CoT: Learning to Internalize CoT Step by Step

CoRR
When leveraging language models for reasoning tasks, generating explicit chain-of-thought (CoT) steps often proves essential for achieving high accuracy in final outputs. In this paper, we investigate if models can be taught to internalize these CoT steps.

WorMa: An Undulatory Robot With Center of Mass Regulation via Internal Fluid Redistribution for Amphibious Locomotion

Advanced Robotics Research, EarlyView.
WorMa is an amphibious undulatory robot that uses Center of Mass redistribution as the sole terrain adaptation mechanism. This mechanism is based on internal fluid mass redistribution through a pump‐driven latex balloon system that creates three profiles: head‐biased, balanced, and tail‐biased.

Selective Feeding and Microalgal Consumption Rates by Crown-Of-Thorns Seastar (Acanthaster cf. solaris) Larvae

Diversity, 2017
Outbreaks of the crown-of-thorns seastar (CoTS) represent a major cause of coral loss on the Great Barrier Reef. Outbreaks can be explained by enhanced larval survival supported by higher phytoplankton availability after flood events, yet little is known

Lime Juice and Vinegar Injections as a Cheap and Natural Alternative to Control COTS Outbreaks. [PDF]

PLoS ONE, 2015
Outbreaks of the corallivorous crown-of-thorns seastar Acanthaster planci (COTS) represent one of the greatest disturbances to coral reef ecosystems in the Indo-Pacific, affecting not only coral reefs but also the coastal communities which rely on their ...

Enhancing Amphibious Flipper‐Based Locomotion Through Terrain‐Dependent Bayesian Optimization of Central Pattern Generator Control

Advanced Robotics Research, EarlyView.
A sea turtle‐inspired amphibious robot uses simulation‐guided optimization to adapt its flipper coordination to different environments. Sensitivity analysis and multiobjective Bayesian optimization identify terrain‐dependent controllers that are validated on hardware.

Vacuums of the sea: Ecological function of large coral reef benthic scavengers in suppressing crown-of-thorns starfish (COTS) outbreaks

Ideas in Ecology and Evolution
Despite their drastic impacts on coral reefs, outbreaks of the coral-feeding seastar crown-of-thorns starfish (COTS), Acanthaster, have remained a scientific enigma.

Multi-species consumer jams and the fall of guarded corals to crown-of-thorns seastar outbreaks [version 2; referees: 2 approved]

F1000Research, 2018
Outbreaks of predatory crown-of-thorns seastars (COTS) can devastate coral reef ecosystems, yet some corals possess mutualistic guardian crabs that defend against COTS attacks.

A Review of the Giant Triton (Charonia tritonis), from Exploitation to Coral Reef Protector?

Diversity, 2022
Charonia tritonis (Charoniidae), one of the largest marine gastropods and an echinoderm specialist, preys on Crown-of-Thorns starfish (CoTS), a recurring pest that continues to be a leading cause of coral mortality on Indo-Pacific reefs.
