The main goal of this study was to understand if, similarly to the fossil record, high quantities of toxic metals induce coccolith dwarfism in coccolithophore species. We investigated, for the first time, the effects of trace metals on coccolithophore species other than E. huxleyi and on coccolith morphology and size. Our data show a species-specific sensitivity to trace metal concentration, allowing the recognition of the most-, intermediate- and least-tolerant taxa to trace metal enrichments.

Short summary
The Toarcian Oceanic Anoxic Event (T-OAE) was cored at Colle di Sogno and Gajum in the Lombardy Basin (northern Italy), where pelagic successions guarantee a continuous record of this paleoenvironmental perturbation. The Sogno and Gajum cores recovered high-quality sediments deposited prior to, during, and after the T-OAE. Ongoing research is devoted to reconstructing the marine ecosystem dynamics and resilience under short- and long-term perturbations analogous to current global changes.

Short summary
Short summary
The ratio of titanium to aluminum (Ti/Al) is an established way to reconstruct North African climate in eastern Mediterranean Sea sediments. We demonstrate here how to obtain reliable Ti/Al data using an efficient scanning method that allows rapid acquisition of long climate records at low expense. Using this method, we reconstruct a 3-million-year North African climate record. African environmental variability was paced predominantly by low-latitude insolation from 3–1.2 million years ago.

Short summary
Short summary
The study of past sedimentary records from coastal margins allows us to reconstruct variations in terrestrial input into the marine realm and to gain insight into continental climatic variability. The study of two sediment cores close to river mouths allowed us to show the potential of long-chain diols as riverine input proxy.

Short summary
The mid-Cretaceous (ca. 121 to 94 Ma) was characterized by a generally warm climate punctuated by supra-regional to global phenomena of widespread ocean anoxia. In this work we present the first complete record of temperature and fertility variations through the mid-Cretaceous in the western Tethys based on calcareous nannofossils. The new record indicates that temperatures and fertility were rather fluctuating but mostly independently, and they were not systematically associated with anoxia.
