Palaeoecological data of KTG core, Katingan, Central Kalimantan, Borneo, Indonesia

K. Anggi Hapsari, Tim Jennerjahn, Septriono Hari Nugroho, Eko Yulianto & Hermann Behling
Southeast Asian peatlands, along with their various important ecosystem services, are mainly distributed in the coastal areas of Sumatra and Borneo. These ecosystems are threatened by coastal development, global warming and sea level rise (SLR). Despite receiving growing attention for their biodiversity and as massive carbon stores, there is still a lack of knowledge on how they initiated and evolved over time, and how they responded to past environmental change, i.e., precipitation, sea level and...

SCUBA belt transects for abundance data H. cochlea and H. aequicostatus

Natalia Herrán
Marine symbioses are integral to the persistence of ecosystem functioning in coral reefs. Solitary corals of the species Heteropsammia cochlea and Heterocyathus aequicostatus have been observed to live in symbiosis with the sipunculan worm Aspidosiphon muelleri muelleri, which inhabits a cavity within the coral, in Zanzibar (Tanzania). The symbiosis of these photosymbiotic corals enables the coral holobiont to move, in fine to coarse unconsolidated substrata, a process termed as “walking”. This allows the coral to...

Data from: Rapid radiation in a highly diverse marine environment

Kosmas Hench, W. Owen McMillan, Oscar Puebla & Martin Helmkampf
Rapid diversification is often observed when founding species invade isolated or newly formed habitats that provide ecological opportunity for adaptive radiation. However, most of the Earth’s diversity arose in diverse environments where ecological opportunities appear to be more constrained. Here, we present a striking example of a rapid radiation in a highly diverse marine habitat. The hamlets, a group of reef fishes from the wider Caribbean, have radiated into a stunning diversity of color patterns...

ADCP current measurements (75 kHz) during RV SONNE cruise SO285

Tim Rixen, Robert Kopte & Tim Dudeck
Upper-ocean velocities along the cruise track of RV SONNE cruise SO285 were continuously collected by a vessel-mounted Teledyne RD Instruments 75 kHz Ocean Surveyor ADCP. The transducer was located at 6.5 m below the water line. The instrument was operated in broadband mode with 5 m bins and a blanking distance of 8.0 m, while 100 bins were recorded using a pulse of 0.82 s. The ship's velocity was calculated from position fixes obtained by...

Continuous thermosalinograph oceanography along RV SONNE cruise track SO285

Michael Schlundt, Tim Rixen & Bernhard Mayer
Underway temperature and salinity data was collected along the cruise track with two autonomous measurement systems, called self-cleaning monitoring boxes (SMBs). Usually, the SMBs are changed after 12 hours. While temperature is taken at the water inlet in about 4 m depth, salinity is estimated within the SMB from conductivity and interior temperature. Salinity was calibrated for each box independently against discrete water samples (see additional attachment). No temperature calibration was performed. For details to...

No short-term effect of sinking microplastics on heterotrophy or sediment clearing in the tropical coral Stylophora pistillata

Sonia Bejarano, Anna Feuring, Valeska Diemel, Mattia Ghilardi & Tilmann Harder
Investigations of encounters between corals and microplastics have, to date, used particle concentrations that are several orders of magnitude above environmentally relevant levels. Here we investigate whether concentrations closer to values reported in tropical coral reefs affect sediment shedding and heterotrophy in reef-building corals. We show that single-pulse microplastic deposition elicits significantly more coral polyp retraction than comparable amounts of calcareous sediments. When deposited separately from sediments, microplastics remain longer on corals than sediments, through...

Microplastics alter feeding strategies of a coral reef organism

Marlena Joppien, Hildegard Westphal, Marleen Stuhr & Steve Doo
Increasing marine microplastic pollution has detrimentally impacted organismal physiology and ecosystem functioning. While previous studies document negative effects of microplastics on coral reef animals, the potential responses of organisms such as Large Benthic Foraminifera (LBF) are largely unknown. Here, we document the impact of microplastics on heterotrophic feeding behavior of LBF. Specimens of Amphistegina gibbosa were incubated in three experimental treatments: (1) Artemia sp. nauplii only; (2) pristine microplastic particles only; (3) choice of nauplii...
