Transplantation of coral fragments is seen as a potential method to rapidly restore cover areas degraded reef; however, considerable research still needed assess the effectiveness transplantation viable reef restoration tool. Initially, during efforts, transplants are attached artificially. Self‐attachment (i.e., growth tissue onto substrate) provides more secure and lasting bond, thus knowledge about self‐attachment times for corals importance restoration. While it known that may generate...
Abstract Nubbins from 12 coral species were transplanted onto dead giant clam shells at three sites in a lagoon near Bolinao, north‐western Philippines. Transplants attached using types of adhesives: cyanoacrylate glue (SG), epoxy putty (EP) and marine (ME) monitored over five months for detachment, situ mortality natural self‐attachment by tissue growth. Corals with SG showed significantly higher rate detachment (logrank test) than those either EP or ME ( P <0.001 each case). Also,...
Abstract With many coral reef areas being degraded whether by anthropogenic or natural causes, a search is on for resilient species of corals that can restore cover where needed, if reefs are to continue provide adequate ecosystem services. A series experiments were undertaken in two sites with different environmental attributes and substrates lagoonal area the northwestern Philippines test potentials local species, Porites cylindrica , rehabilitation. use asexual fragmentation donor...

Abstract The scleractinian coral Montipora digitata (Acroporidae) is a common reef flat species that thrives under high levels of light and water turbulence, propagates successfully by natural fragmentation. It was used for transplantation experiments in an attempt to restore degraded lagoon environment the northwestern Philippines. Branches about 5 cm from population were transplanted dead outcrops or knolls two locations (Binlab Malilnep-Ac) with different environmental characteristics....
Abstract Sexual and asexual modes of coral propagation are used to produce materials actively restore cover on degraded reefs. It is important evaluate growth, survival cost‐effectiveness prior any large‐scale intervention. This study compared the cost using sexually, with asexually, propagated Acropora granulosa at an in situ nursery and, subsequently, reef patches north‐western Philippines. For sexual propagation, gametes spawned from gravid A. colonies were collected, fertilized reared...

The benthic habitats on the Philippine (Benham) Rise were unknown until joint University of Philippines Marine Science Institute (UPMSI)/University Los Baños (UPLB)/Department Agriculture-Bureau Fisheries and Aquatic Resources (DA-BFAR) cruise May 2014 when extensive coral reefs discovered summit Benham Bank Seamount. Short observational surveys five stations at depths up to 55 m revealed that pristine with excellent cover mostly by tiered, thick, rigid foliose plate-forming Porites...
The responses of coral reef flat microphytobenthos to short‐term exposure elevated levels inorganic nitrogen (N) and phosphorus (P) were investigated in 1994 1995. Sand samples collected from the maintained over 7 d triplicate cultures with N‐enriched (100 µM NO 3 ), P‐enriched (10 PO 4 ambient seawater. A fourth experiment used a treatment combined N P enrichment. sediment assessed for chlorophyll (Chl ) content photosynthesis‐irradiance (P‐I) responses. P‐I curves, constructed area‐and Chl...
The present century is witness to unprecedented levels of coral reef degradation worldwide.Current understanding based on traditional ideas unlikely capture adequately the dynamics phenomena accompanying this trend.In regard, complexity are reviewed.Some applications reefs as complex systems have already been discussed in literature although further progress warranted search for new and more effective management tools continues, direction towards holistic, integrative large scale approaches...
Abstract The brooding reef-building octocoral Heliopora is widespread on Indo-West Pacific reefs and appears to be relatively resistant thermal stress, which may enable it persist locally while scleractinians diminish under Anthropocene conditions. However, basic physiological measurements of “blue corals” are lacking prevent their inclusion in trait-based studies. We address this by quantifying rates (mean ± SE) linear extension (0.86 0.05 cm yr −1 ) skeletal density (2.01 0.06 g −3...

Four sets of nutrient enrichment experiments were carried out in 1994 and 1995 using sieved sand from a coral reef flat the northwestern Philippines.The samples, prepared by packing sediment glass petri dishes, maintained for 7 days outdoor microcosms with varying nitrogen:phosphorus (N:P) ratios overlying water.The objective study was to detect changes composition metabolism communities over short-term exposures.Net primary production respiration rates microalgae increased within few...
