Characterization of doublesex and nanos genes in Acropora millepora
Scleractinian coral, Acropora millepora is a hermaphroditic species which develops both male and female gonads in each polyp at the same time. Corals are diploblastic metazoa and have a simple body structure without well-defined organs. They lack typical reproductive system. Instead, eggs and …

Species boundaries in scleractinian corals: a case study of the Acropora humilis species group
… of evolutionary relationships in species of the Acropora humilis species group. Reproductive criteria, including relative timing of spawning and potential to interbreed in fertilization experiments, provided the greatest level of taxonomic resolution. Discriminant analysis of morphometric data …

Characterisation of anterior patterning genes in the staghorn coral, Acropora millepora(Cnidaria; Anthozoa; Scleractinia)
… in bilaterians, in the basal cnidarian Acropora millepora. In Acropora, a gene clearly related to the ems/Emx family was shown to be expressed in a subset of presumed neurons, restricted along the oral-aboral (O/A) axis to the aboral end of the planula larva, in a pattern overlapping …

A mechanistic approach to understanding and predicting hydrodynamic disturbance on coral reefs
… morphologically disparate species (submassive Acropora palifera [Subgenus Isopora], corymbose Acropora gemmifera and tabular Acropora hyacinthus) and the strength of the reef substrate were investigated spatially at a hydrodynamicallyexposed shallow reef platform (Lizard Island, Australia) to …

Influences of benthic algae on coral settlement and post-settlement survival: implications for the recovery of disturbed and degraded reefs
… by algal turfs, on settlement of the coral Acropora millepora. Adding sediment reduced settlement but the effects of different algal turfs varied, a newly established (<6 week old) and relatively ungrazed turf reducing settlement, and a well established turf (up to 2.5 years) and grazed turf …

Temporal variation in the coral reefs of the east coast of the inner gulf of Thailand
… reef community types dominated by 1) Porites, 2) Acropora and 3) zoantharians. The reefs are developed under naturally turbid conditions and relatively low salinity due to the proximity of four major river outlets located in the uppermost area of the gulf. The number of Acroporid species on the …

USING DEEP LEARNING AND UAV IMAGERY TO DETECT ELKHORN CORAL IN ST. CROIX’S EAST END MARINE PARK
<p>Elkhorn coral, or <em>Acropora palmata</em>, is an important reef building species that promotes species abundance and other ecological services to the communities in the US Virgin Islands. We captured high resolution imagery of a reef in St. Croix’s East End Marine Park using a Wingtra One UAV. …

Biogenic buildups and carbonate sedimentation, Dry Tortugas Reef Complex, Florida
… lagoonal bank, 2) Montastrea reef bank and 3) <i>Acropora palmata</i> reef. These facies lie adjacent to one another and are also present in vertical succession as individual growth stages of varying thickness and lateral extent. A zone of <i>Acropora gervicornis</i> is developed as a transition …

Assessing the risk of ocean acidification for scleractinian corals on the Great Barrier Reef
… This research investigates the response of Acropora aspera using pulse amplitude modulation (PAM) fluorometry and oxygen respirometry under increased pCO₂ with concomitant high light conditions. The dinoflagellate density and HPLC pigment analysis are utilised to characterise the CO₂₋induced …

The ecology and microbiology of black band disease and brown band syndrome on the Great Barrier Reef
… of black band disease (BBD) on the coral Acropora muricata was measured and compared between seasonal field studies at Lizard Island on the Great Barrier Reef (GBR). BBD progressed along and transmitted between coral branches at a significantly faster rate during the austral summer month …

U-series dating of diagenetically altered fossil reef corals and the application for sea level reconstruction
… Methoden datiert werden können. Die Acropora palmata und Diploria strigosa Korallen aus Barbados zeigen einen geringeren Grad diagenetischer Veränderungen. Es wird gezeigt, dass diese Korallen durch einen anderen Prozess beeinflusst wurden als die Korallen aus Aqaba. Daher können sie …

Production of Dimethyl Sulphide (DMS) by Scleractinian Coral during Aerial Exposure – Effect of Temperature and Light
… during emersion were observed between species; Acropora inermis production increased significantly upon exposure (from ~20 to ~600 nmol/h/cm2) with Turbinaria reniformis also increasing but to a lesser degree. No significant increase was observed in Porites cylindrica. Prolonged acclimation to …

Small RNA studies in Drosophila melanogaster, Stylophora pistillata and Symbiodinium sp.
… there is another coral genome available — from Acropora digitifera — but the large evolutionary distance between both corals (about 240 million years apart) warrants in-depth study of our coral of interest. On the other hand, our Symbiodinium genome will be the first of its kind for any …

Tropical stony corals host diverse microbial nitrogen dynamics
… This is in contrast with the elkhorn coral, Acropora palmata, which hosts minimal active nitrogen metabolism directly. Species sampled at multiple sites (Porites porites and Orbicella faveolata) showed similar trends among replicates and within genera (Porites). We also examine the impact of …

Effects of Temperature stress on coral fluorescence and reflectance
… experiments on three Caribbean species of coral: Acropora cervicornis, Orbicella annularis, and Porites furcata. All species exhibited signs of stress and bleaching after the experiment, based on their chlorophyll fluorescence and reflectance responses. Upon exposure to water temperatures raised …

Taxonomy and ecology of South African reef corals
… Testing fragment survival of the hard coral Acropora austera confirmed the assumption that wave action is an important factor shaping coral communities by only allowing this species to dominate in depths greater than 18m. Four hard- and five soft coral species were used to quantify the …
