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...

Shallow-marine carbonate cementation in Holocene segments of the calcifying green alga Halimeda

Thomas Mann , André Wizemann , Marleen Stuhr , Yannis Kappelamann , Alexander Janßen , Jamaluddin Jompa & Hildegard Westphal
Early-diagenetic cementation of tropical carbonates results from the combination of numerous physico-chemical and biological processes. In the marine phreatic environment it represents an essential mechanism for the development and stabilization of carbonate platforms. However, many early-diagenetic cements that developed in the marine phreatic environment are likely to become obliterated during later stages of meteoric or burial diagenesis. In this contribution, a petrographic microfacies analysis of Holocene Halimeda segments collected on a coral island in the...
