Behavioral plasticity of nocturnal marine organisms under interspecific competitive pressure
Pacific abalone (Haliotis discus hannai) are typical nocturnal organisms in the marine benthic ecosystem. However, whether their rhythmic behavior is related to the avoidance of interspecific competition for food resources is unknown.

Conspecific alarm cues crushed from Mesocentrotus nudus prevent sea urchinsĀ from foraging the kelp, but do not repel them far away from the kelp. However, it remains largely unknown of whether this phenomenon was affected by conspecific alarm cues or by ...

Sea urchin utilisation in Eastern Indonesia
Sea urchins have long been an important component of gleaning invertebrate fisheries and are valued for their highly nutritious gonads. Sea urchin fisheries are often unreported and unregulated, despite increasing indications of overexploitation. Data on

Inside or Outside the Pits : Variable Mobility in Conspecific Sea Urchin, Anthocidaris crassispina (A. Agassiz) [PDF]
The sea urchin Anthocidaris crassispina (A. Agassiz) lives either in small pits or outside the pits on rock surfaces. Difference in movement between individuals living inside and outside the pits was investigated. Sea urchins living inside the pits never

Sea Urchin Recruitment: Effect of Substrate Selection on Juvenile Distribution [PDF]
Intertidal field observations have shown that juvenile purple sea urchins Strongylocentwtus purpuratus are found in higher densities near adults . The same is true for subtidal populations of juvenile red sea urchins 5. franciscanus.

The behavior of sympatric sea urchin species across an ecosystem state gradient [PDF]
Background In temperate macroalgal forests, sea urchins are considered as a keystone species due to their grazing ability. Given their potential to shape benthic communities, we monitored the habitat use by three sympatric sea urchin species and compared

Species and Abundance of Sea Urchins (Diadematidae) on Different Environmental Pressure Conditions
Genetic diversity of sea urchin are very high; there are no two organisms of the same species that are exactly alike. Dense aggregation of sea urchin is responsible for the destruction of marine algae communities on coral reef ecosystem.
