Understanding the murky origins of coral diversity in the Coral Triangle
Studies on coral communities living in marginal
conditions (i.e. low light, high turbidity, extreme temperatures, high
nutrients) are important to understand how coral reefs will respond to current
global changes. The Kutai Basin (East Kalimantan (Indonesia) contains a rich
and well-preserved Miocene fossil record of small patch reefs that developed
under the influence of high siliciclastic inputs from the Mahakam Delta. Conversely,
palaeontological and molecular studies suggest that the Miocene was an
Naturalis visit
Vedrana Pretković (Granada University) and Nadia Santodomingo (NHM London) visited Naturalis museum during the last week. A small meeting was arranged to discuss progress on one of our publications with the ESRs based in the Netherlands, Nathan Marshall and Vibor Novak.
We also welcome our colleague Aries Kusworo from Indonesia, who is currently working with Sonja Reich and Frank Wesselingh on mollusks from the Bontang gardens.
Towards a synthesis of Cenozoic pantropical paleontology
The tropics hold the most diverse shallow marine ecosystems, and play a major role in controlling global climate. Study of past ecosystem response to environmental change provides critical information for understanding the long-term impacts of ongoing environmental change. Global changes are modulated by local environmental factors resulting in a regional pattern of biotic response. Each region can be thought of as treatments of a global-scale natural experiment. Was the response of ecosystems to rapid global changes similar?
Origins of coral diversity in Southeast Asia
Southeast Asia hosts the maximum centre of coral diversity. Evidence from palaeontological and molecular studies suggests that the Miocene was an important period for diversification in the region. However, the fossil record is markedly undersampled. Of the ~200 species of azooxanthellate corals present in the region, only 49 species are known in the fossil record.

Meeting (Utrecht University): Origins of the South East Asian Marine Biodiversity Maximum
In order to start our connexion with Utrecht University as part of our PhD activities, we will have a meeting on next Tuesday 4 October. A general overview of the project will be presented by Willem Renema, followed by talks about the geology of the Mahakan Delta (Nathan Marshall), as well as the biodiversity of Foraminifera (Vibor Novak), Mollusca (Sonja Reich), Bryozoa (Emanuela Di Martino), and Corals (Nadia Santodomingo). In addition, Viola Warter will show some preliminary results about the geochemistry.
Welcome to new ESR: Viola Warter!
Viola joined the project at the beginning of this month, and she will cover the geochemistry component at the Royal Holloway University. She is visiting today the Natural History Museum, and I took advantage to take a picture with one of our nice Coral samples!
Samples: First tally!
Today was a rainy day in Bontang, the base camp. Luckily, we
had decided to stay at the hotel to organize the samples and fill out the spreadsheets. Only one week of duties and we have already collected about
270 sample bags!! Look at the piles for yourselves... and just imagine the
amount of work we have in front.
