Introduction
Hi! I am working on coral reef benthic community ecology, with a specific interest on octocoral diversity and ecology.

Soft corals in the Philippines have received little attention. In this study, community structure and size-frequency distribution of soft corals were assessed via quantitative surveys in a heavily disturbed reef system in northwestern Philippines. Relationships between selected environmental parameters and benthic components were also investigated....
Octocorals are relatively understudied than other coral reef organisms despite their ecological and economic values. The Philippines is known to have high marine biodiversity, but information on octocorals is lacking. This study investigated spatial and temporal variations in the assemblage of octocorals in selected reef sites in the West Philippin...
Shallow water coral reefs in many parts of the world are experiencing phase shifts due to various disturbances, resulting in increases in the abundance of algal assemblages and non-scleractinian taxa, including soft corals (Octocorallia). However, the effects of these changes on reef-associated macrofauna are still not fully understood. In this stu...
Nanipora Miyazaki & Reimer, 2015 is a recently described monotypic octocoral genus belonging to the family Helioporidae (class Octocorallia). Nanipora kamurai Miyazaki & Reimer, 2015 was formally described from shallow coral reefs around Zamami Island, within Kerama-shoto National Park, in Okinawa Prefecture, southern Japan. To date, Nanipora has b...
The Philippine blue sponge, Xestospongia sp., is a potential source of natural products for pharmaceutical use. However, knowledge on different aspects of its biology and ecology is still lacking, and improvement on biomass production through mariculture is still needed. In this study, we conducted ecological surveys and open sea mariculture trials...
Competition among benthic organisms plays an important role in coral population dynamics in degraded reefs. In this study, interspecific interactions between scleractinians and octocorals and larval settlement of scleractinians near selected octocorals in Lucero, a degraded reef in Bolinao, Pangasinan, northwestern Philippines were assessed. Compet...
Zooxanthellae (genus Symbiodinium spp.) are symbiotic photosynthetic dinoflagellates that provide the host coral with metabolic products crucial for growth. Zooxanthellae density can serve as proxy in evaluating the physiology and health of corals. However, few studies on zooxanthellae have been conducted in the most biodiverse yet disturbed reefs...
The Coral Triangle Conservancy conducted a preliminary coastline and seagrass survey for Nasugbu, Batangas as part of its future aims to designate three large marine managed areas and a seagrass sanctuary within the jurisdiction of the municipality of Nasugbu. This is the first in depth study completed on seagrass along the 70 km Nasugbu coastline....
