V Factor is a new programme at the Natural History Museum in London. It offers volunteers\ the chance to work in public view alongside Museum scientists on collection-based research\ and curation projects, taking them from visitor to proactive volunteer. It aims to involve a volunteers\ project manager, scientists, curators, volunteers and the public in the museum\’s research.\ Volunteers work alongside scientists on a research project whilst benefiting from a unique, informal and fun learning experience. Visitors are able to observe the processing of\ samples and interact with those involved. The management of this volunteer programme is\ described in this paper. The pilot project was \‘Throughflow\’; an international study of Southeast\ Asian fossil corals as a means to describe the high biodiversity of their ecosystem and the\ effects of environmental change. Volunteers have successfully assisted with the cleaning of\ specimens so that they may be curated. At the same time, they have been discussing with experts project-related information, collections care, and the role of museums today. The programme\ has been continuously evaluated and changed as felt necessary. By March 2013, 45\ volunteers were involved. Outcomes have included improved volunteer talent and education\ management, excellent assistance with scientific work and novel means of attracting the public\ to the museum\’s work.

Evidences from palaeontological and molecular studies suggest that the formation of the SE Asian ancestral centre of diversity occurred during the Miocene. Under the umbrella of the Throughflow project, delta-front patch reefs from 42 outcrops were studied in East Kalimantan (Indonesia), including extensive collections of tens of thousands of specimens within 265 samples. This research aims to answer how diverse were corals during the Miocene and which environmental factors played a role in their diversification on both, temporal and spatial scales. Coral morphologies seem to respond to the gradient of siliciclastic input created by the Mahakan Delta system. Platy-coral assemblages were common in the vicinity of the delta, characterized by a higher turbid-water regime, and mainly from the Early to Middle Miocene (up to Serravallian age). On the other hand, communities of branching corals mixed with scattered massive coral heads were more frequent during the Late Miocene (Tortonian to Messinian age) in settings located towards the north, far-off the delta influence. Although preliminary (\<10\% of samples examined), species diversity was high in both platy and branching coral assemblages, and comparable to modern coral settings living under similar environmental conditions. A total of 51 morphospecies (36 genera) have been identified so far, from which only three genera are considered as extinct, Dictyaraea, Anisocoenia, and Fungophyllia. Whether the observed species turnover is due to major global environmental changes after the Middle Miocene, or it is merely explained by switching of the Mahakan Delta gradient, or a combination of both, is an aspect to be examined in further integrated analysis including geochemistry and sedimentology.

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. As part of the Throughflow ITN project, we are collecting new data to document the Miocene diversity of zooxanthellate and azooxanthellate scleractinians from shallow and deep-water habitats preserved in outcrops of East Kalimantan (5-20 Million years old). This project has completed two five-week long field seasons and is currently processing samples. So far, we have identified the azooxanthellate taxa Caryophyllia, Stephanocyathus, Flabellum, Heterocyathus, and Madrepora. Preservation can be excellent allowing geochemical analysis to understand the paleoenviromental conditions in which these species were living. In combination with parallel studies on shallow water ecosystems, these new data provide insights to the origins of the high diversity in this region.

Reefs in the Coral Triangle host the richest coral diversity today, and palaeontological and molecular evidence suggest that the Miocene (5-23 Ma) was an important period for diversification in this region. As part of the Throughflow ITN, the aims of this study are to determine which coral species occurred during this period and to understand how environmental factors controlled coral diversification on both temporal and spatial scales. Our new collections include tens of thousands of specimens from the rich and well-preserved Miocene fossil record of small patch reefs that developed in turbid habitats that are now preserved in the sediments of the Kutai Basin of East Kalimantan (Indonesia). Preliminary results suggest that species diversity was high and comparable to modern coral settings living under turbid environmental conditions. A total of 150 morphospecies from 70 genera have been identified, including nine genera known as extinct. Our findings have revealed that some lineages that were previously known from the Plio-Pleistocene record were already present during the Miocene time. These discoveries have a profound impact on our understanding of the origins of today\’s diversity in the Coral Triangle. Further research will focus on the incorporation of these fossils into phylogenetic analyses in order to estimate divergence times and explore the relationship of evolutionary trends with environmental changes at biogeographic scale.

Currently, SE Asia is the global marine centre of diversity. High diversity is concentrated in and around reefs. A large variety of organisms, including corals and fish, but also molluscs, crustaceans and echinoderms contribute to this high diversity. In order to understand the timing and the context of the origin of the modern biodiversity hotspot, the fossil record needs to be documented. However, reef facies often suffer strong diagenesis, compromising the fossil record of reef and reef-associated organisms. Here we present an assessment of a well-preserved Late Miocene mollusc fauna from Bontang (East Kalimantan, Indonesia). The fauna is found in association with branching corals, dominated by Dictyaraea. The mollusc fauna is dominated by predatory and browsing carnivorous snails and includes reefal indicators such as the gastropod Coralliophyla and the bivalve Tridacna. The new Bontang fauna gives a glimpse of the diversity and ecological composition of a Late Miocene mollusc fauna from a so-called coral-carpet environment.

Most studies of Cenozoic shallow-water, mixed carbonate-siliciclastic depositional systems have focused on their sedimentology. To date, however, comprehensive analyses of biotas and biofacies of Indo-West Pacific reefs that developed in mixed carbonate-siliciclastic systems are lacking. This study describes the palaeoenvironment and biodiversity of a late Burdigalian patch reef that developed in a mixed carbonate-siliciclastic depositional system. The studied exposure is located at the northeast margin of the Kutai Basin near Bontang (Indonesia), and is approximately 80 m wide and 25 m thick. Multi-taxon analysis of the most abundant fossil groups, including larger benthic foraminifera, corals, coralline algae, and bryozoans, aims to provide a model for environmental interpretation that will allow comparison with similar deposits of Indo-West Pacific region. Based on fossil content and lithology, five different facies types have been distinguished: foraminiferal packstone (FP), bioclastic packstone with foralgal communities (BP), thin-platy coral sheetstone (CS), platy-tabular coral platestone (CP), and shales (S). Among larger benthic foraminifera, smaller and more robust forms dominate in the FP and BP facies, while larger and flatter forms are the most abundant in the CS and CP facies. Thin-platy corals are dominant in the CS facies and gradually change into thicker platy-tabular forms in the CP facies. Assemblages and growth forms of coralline algae show no major differences between the facies types and are dominated by melobesioids and Sporolithon. The majority of bryozoan species are encrusting and were found only in the CS facies. Light-dependent organisms occurring in the reef indicate low light conditions typical for mesophotic reefs. The relatively small size of this reef complex and quite distinct vertical changes in the facies types, combined with the high siliciclastic content in most of the units, points to strong terrigenous input affecting water transparency as the main factor controlling the reef growth.

Their role as rapid colonizers of new substrates has been suggested, but little is still known to support this idea. To address this question, larger benthic foraminifera assemblages have been studied in the paleoenvironmental reconstruction of a Langhian (Middle Miocene) shallow-water patch reef, as part of a broader multitaxon fossil comunity analysis, including corals, coralline algae, and bryozoans. The studied outcrop (approx. 80 m wide and 25 m thick) is located at the northeast margin of the Kutai Basin near Bontang (Indonesia). The patch-reef was developed in mixed carbonate-siliciclastic depositional environment and despite the high terrigenous input affecting water transparency, this reef contains a diverse marine biota. Five different facies types were distinguished based on lithology and fossil content: foraminifera packstone, bioclastic packstone with foralgal communities, thin-platy coral sheetstone, platy-tabular coral platestone, and shales. Excluding the fossil barren shales facies, only larger benthic foraminifera occur in all four remaining facies types, showing the ability to rapidly adapt to changes in environment. In the current study, high siliciclastic input caused fluctuations in light levels, but also resulted in deposition of soft-bottom substrate. In newly developed conditions, the larger benthic foraminifera appear first and mark the initiation of reef growth. The persistence of LBF throughout the fossil reef succession indicates their high tolerance to terrigenous input and also highlight the role of foraminifera as primary colonizers, proving themselves as important faunal pioneers, particularly in mixed carbonate-siliciclastic systems.}, author = {Vibor Novak and Nadiezhda Santodomingo and Willem Renema} } @conference {1992, title = {Origins of coral diversity in Southeast Asia}, booktitle = {5th International Symposium on Deep-Sea Corals 2012}, year = {2012}, month = {1-6 April 2012}, address = {Amsterdam, The Netherlands}, author = {Nadiezhda Santodomingo and Kenneth G.
