Article
Full-text available
The Suwannee Limestone of Florida and Georgia, USA, is a carbonate paleoenvironment with a rich diversity of marine fossils. These record the presence of coral-and seagrass-bearing communities in the western Atlantic from the Eocene/Oligocene boundary to the mid Oligocene (33.9-28.). From the Suwannee Limestone, we describe two new species of the c...

The staghorn coral genus Acropora is the most diverse living genus of reef-building corals. From earliest records around the K-Pg event, the genus has a geo-history of strongly persistent morphological lineages, dating from 49 Mya to present and extending across Eocene England and Europe, Oligocene to early Miocene Europe, Oligocene to present west...
Article
The genus Alveopora is a scleractinian coral taxon whose phylogenetic classification has recently changed from the family Poritidae to Acroporidae. This change, which was made based on single-locus genetic data, has led to uncertainty about the placement of Alveopora and the ability for deep evolutionary relationships in these groups to be accurate...

Abstract The zooxanthellate scleractinian genus Acropora (Acroporidae) dominates many shallow-reef areas across the Indo-Pacific, but has recently been recognised as a component of deep-reef assemblages with only a few records below 60 m depth. Here, we report on Acropora tenella (Brook, 1892) growing to 110-m depth in the western Coral Sea, equal...

In their recent letter, Madin et al. (2016) dispute our findings in Muir et al. (2015a) that reduced levels of light during winter confine staghorn corals to shallower depths at higher latitudes and will ultimately limit their scope for latitudinal expansion as oceans warm. We based our conclusions on a rich global dataset analysed using two types...
Article
Full-text available
Zooxanthellate corals are found throughout the tropics, but also extend into subtropical and marginal locations due to the presence of warm ocean currents. The population history of corals in marginal locations is of great interest in relation to changing global climatic con- ditions, as species edge zones might play an important role in evolutiona...
Article
Full-text available
Today coral reefs are threatened by changes to seawater conditions associated with rapid anthropogenic global climate change. Yet, since the Cenozoic, these organisms have experienced major fluctuations in atmospheric CO2 levels (from greenhouse conditions of high pCO2 in the Eocene to low pCO2 ice-house conditions in the Oligocene-Miocene) and a d...
Article
Full-text available
As one of the most prolific and widespread reef builders, the staghorn coral Acropora holds a disproportionately large role in how coral reefs will respond to accelerating anthropogenic change. We show that although Acropora has a diverse history extended over the past 50 million years, it was not a dominant reef builder until the onset of high-amp...

Rapa (27°36′ S, 144°20′ W) is a small (~40 km2) volcanic island isolated in the Southern Austral Archipelago, where direct anthropogenic stressors are extremely limited. Here, we present the results of the first quantitative survey of coral community structure across habitats and depths around the island. Despite its geographical isolation in the d...

Trait-based approaches advance ecological and evolutionary research because traits provide a strong link to an organism's function and fitness. Trait-based research might lead to a deeper understanding of the functions of, and services provided by, ecosystems, thereby improving management, which is vital in the current era of rapid environmental ch...
Article
Although Acropora is the most diverse and abundant coral genus on modern Indo-Pacific reefs, there is only limited understanding of its evolutionary history in the region. To help fill this gap, we consider the fossil record of Acropora and its sister clade Isopora, through examination of new extensive collections of well-preserved specimens from E...
Article
Full-text available
An analysis of present-day global depth distributions of reef-building corals and underlying environmental drivers contradicts a commonly held belief that ocean warming will promote tropical coral expansion into temperate latitudes. Using a global data set of a major group of reef corals, we found that corals were confined to shallower depths at hi...

Four new species and new records for six species of the highly successful reef-building coral genus Acropora are described from Oligocene and Early Miocene (Rupelian to Burdigalian) localities in Europe. Acropora slovenica sp. nov. is described from Slovenia (Gornji Grad beds); A. piedmontensis sp. nov. and A. macrocalyx sp. nov. from the Torino Hi...
Article
Full-text available
Based on only a handful of mitochondrial and nuclear loci, the phylogenetic relationships within the genus Acropora have been unclear. However, with the new sequencing technology of massively parallel sequencing (MPS), the inter-specific relationships within Acropora may be resolved. We performed multiplex sequencing of the mitochondrial genome of...
Article
Full-text available
The susceptibility of reef-building corals to climatic anomalies is well documented and a cause of great concern for the future of coral reefs. Reef corals are normally considered to tolerate only a narrow range of climatic conditions with only a small number of species considered heat-tolerant. Occasionally however, corals can be seen thriving in...

The family Poritidae formerly included 6 genera: Alveopora, Goniopora, Machadoporites, Porites, Poritipora, and Stylaraea. Morphologically, the genera can be differentiated based on the number of tentacles, the number of septa and their arrangement, the length of the polyp column, and the diameter of the corallites. However, the phylogenetic relati...
