Acropora donei

Acropora donei is a stony coral belonging to the family Acroporidae, forming colonies with distinctive corymbose branching structures made up of small, densely packed branchlets. Like other reef-building corals, it hosts symbiotic algae (zooxanthellae) within its tissues, which provide the coral with nutrients through photosynthesis while the coral provides shelter and access to sunlight. This species contributes to the physical structure of reef systems, offering habitat complexity that supports fish and invertebrate communities.

Acropora donei occupies marine neritic waters across a broad Indo-Pacific range, with recorded populations in Madagascar, Australia, Thailand, Mayotte, Taiwan, Japan, Palau, and Yemen. It is typically found on reef slopes and in shallow, clear-water reef environments.

The species faces a wide array of ongoing pressures. Fishing and harvesting activities, along with recreational use of reef areas, cause direct physical damage. Water quality is degraded by domestic and urban wastewater, agricultural runoff, and solid waste pollution.

Coastal development and other ecosystem modifications alter surrounding habitat, while storms and flooding cause episodic structural damage to colonies. The species is also vulnerable to disease outbreaks, predation by native species such as crown-of-thorns starfish, and competition or disruption from invasive organisms. Broader habitat shifting linked to environmental change compounds these localized stressors.

Conservation efforts affecting this species include its listing under international trade regulations, inclusion in marine protected areas across parts of its range, and ongoing reef monitoring programs that track coral cover and health. Some regions have implemented water quality management and fisheries regulations aimed at reducing direct reef degradation.

Given the combination of chronic pollution, physical disturbance, and climate-linked stress, the population trend for Acropora donei is decreasing, and its long-term outlook remains concerning without sustained reduction in cumulative threats.
