We present a dataset of 23032 fossil occurrences of marine organisms from the Late Miocene to the Early Pliocene (~11 to 3.6 million years ago) from the Mediterranean Sea. This dataset will allow us, for the first time, to quantify the biodiversity impact of the Messinian salinity crisis, a major geological event that possibly changed global and regional climate and biota.

Bowl-shaped spirorbid microbialite bioherms formed during the late Middle Miocene (Sarmatian) in the central Paratethys Sea under a warm, arid climate. The microbialites and the surrounding sediment document a predominance of microbial activity in the shallow marine environments of the sea at that time. Modern microbialites are not analogues for these unique structures, which reflect a series of growth stages with an initial “start-up stage”, massive “keep-up stage” and termination of growth.

We present the first analysis of population structure and cohort distribution in a fossil oyster reef. Data are derived from Terrestrial Laser Scanning of a Miocene shell bed covering 459 m². A growth model was calculated, revealing this species as the giant oyster Crassostrea gryphoides was the fastest growing oyster known so far. The shell half-lives range around few years, indicating that oyster reefs were geologically short-lived structures, which were degraded on a decadal scale.

High-resolution analyses of paleoecological and geochemical proxies give insight into environmental processes and climate variations in the past on a timescale that is relevant for humans. This study, as the first of its kind, aims to resolve cyclic variations of nannofossil assemblages on a decadal to centennial scale in a highly sensitive Early Miocene (~17Ma) shallow marine setting. Our results indicate that solar variation played a major role in shaping short-term climate variability.

The Benguela Upwelling System is a region in the SE Atlantic Ocean of high biological productivity. It comprises several water masses such as the Benguela Current, South Atlantic Central Water, and Indian Ocean Agulhas waters. We analyzed planktonic foraminifera from IODP Sites U1575 and U1576 to characterize water masses and their interplay in the Pleistocene. This defined changes in the local thermocline, which were linked to long-term Benguela Niño- and Niña-like and deglaciation events.

We provided novel insights into the behaviour of a major upwelling cell between 15 and 8.5 million years ago. To study changing conditions, we apply a combination of geochemical and paleoecological parameters to characterize the nutrient availability and subsequent utilization by planktonic primary producers. These changes we then juxtapose with established records of contemporary monsoon wind intensification and changing high-latitude processes to explain shifts in the plankton community.

We identified the provenance, (post)depositional history, weathering conditions and hydroclimate that formed the detrital and authigenic silicates and soil carbonates of the Valley of Lakes sediments in Central Asia during the Cenozoic (~34 to 21 Ma). Aridification pulses in continental Central Asia coincide with marine glaciation events and are caused by Cenozoic climate forcing and the exhumation of the Tian Shan, Hangay and Altai mountains, which reduced the moisture influx by westerly winds.

How environmental change affects a species' phenotype is crucial for taxonomy and biodiversity assessments and for their application as paleoecological indicators. Morphometric data of a Neotropical ostracod species, as well as several climatic and hydrochemical variables, were used to investigate the link between morphology and environmental conditions. Temperature seasonality, annual precipitation, and chloride and sulphate concentrations were identified as drivers for ostracod ecophenotypy.

We study the variability in Mediterranean–Atlantic exchange, focusing on the surface Atlantic inflow across the mid-Pliocene warm period and the onset of the Northern Hemisphere glaciation, still unresolved by previous works. Oxygen isotope gradients between both sides of the Strait of Gibraltar reveal weak inflow during warm periods that turns stronger during severe glacials and the start of a negative feedback between exchange at the Strait and the Atlantic Meridional Overturning Circulation.

Isotopic signatures of ostracods from Florida correlate with their host water, implying a regional influence of temperature and precipitation. Calculated monthly configurations of a theoretical calcite formed in rivers were compared to ostracod isotope compositions. The data suggest a seasonal shell formation during early spring that is coupled to the hydrological cycle of the region. The surprising seasonality of the investigated ostracods is of importance for paleontological interpretation.

Lake Ohrid is considered to be the oldest existing lake in Europe. Moreover, it has a very high degree of endemic biodiversity. During a drilling campaign at Lake Ohrid in 2013, a 569 m long sediment sequence was recovered from Lake Ohrid. The ongoing studies of this record provide first important information on the environmental and evolutionary history of the lake and the reasons for its high endimic biodiversity.

We report on a planned Trans-Amazon Drilling Project (TADP) that will continuously sample Late Cretaceous to modern sediment in a transect along the equatorial Amazon of Brazil, from the Andean foreland to the Atlantic Ocean. The TADP will document the evolution of the Neotropical forest and will link biotic diversification to changes in the physical environment, including climate, tectonism, and landscape. We will also sample the ca. 200Ma basaltic sills that underlie much of the Amazon.

Based on our molecular data and performed analyses we found that the gastropods studied represent a comparatively old group that most likely evolved with a constant rate of diversification. However, preliminary data of the SCOPSCO deep-drilling program indicate signatures of environmental/climatic perturbations in Lake Ohrid. We therefore propose that the constant rate observed has been caused by a potential lack of catastrophic environmental events and/or a high ecosystem resilience.

At the foot of the Himalayas in Nepal, land cover time series and data of environmental drivers show changes in disturbance-dependent grasslands that serve as habitat for endangered megafauna. The changes in surface area and heterogeneity of the grassland patches are attributed to a relocation of the dominant river channel of the Karnali River and associated decline of hydromorphological disturbances and a decrease in anthropogenic disturbances after its establishment as conservation area.

We evaluate the relationships between geodiversity, limnological conditions, and freshwater ostracodes from southern Mexico to Nicaragua. Geological, limnological, geochemical, and mineralogical characteristics of 76 systems reveal two main limnological regions and seven subregions. Water ionic and sediment composition are the most influential. Geodiversity strongly influences limnological conditions, which in turn influence ostracode composition and distribution.

Aquatic tundra plants dominate productivity and methane fluxes in the Arctic coastal plain. We assessed how environmental nutrient availability influences production of biomass and greenness of aquatic tundra. We found phosphorous to be the main nutrient limiting biomass productivity and greenness in Arctic aquatic grasses. This study highlights the importance of nutrient pools and mobilization between terrestrial–aquatic systems and their influence on regional carbon and energy feedbacks.

Cryoconite holes are ponds on the glacier surface that play an important role in glacier nutrient pathways. This paper presents the first description of the carbon and nitrogen isotopic composition of cryoconite consumers (tardigrades and rotifers) and their potential food. We showed that consumers differ in nitrogen isotopes and carbon isotopes vary between taxa and between glaciers. The study contributes to improving knowledge about cryoconite hole functioning and cryoconite trophic networks.

Across North America and Europe, goose populations have increased exponentially in response to agricultural intensification. By using an experimental approach, we empirically demonstrated that geese act as bio-vectors, making terrestrial nutrients more bioavailable to freshwater systems. The study revealed that the nutrient loading from goose faeces has the potential to change phytoplankton community composition, with a shift toward an increased presence of cyanobacteria.

Based on classical concepts in ecology, and a literature survey, we highlight the importance of flooded land as a preferential source of atmospheric carbon to aquatic systems at the global scale. Studies in terrestrial and aquatic ecosystems could be reconciled by considering the occurrence of an efficient wetland CO2 pump to river systems. New methodological approaches coupling hydrology and ecology are also necessary to improve scientific knowledge on carbon fluxes at the land–water interface.

The diversity of microalgae and cyanobacteria in cryoconites on three high-Arctic glaciers was investigated. Possible bottom-up controls via nutrient limitation, wind dispersal, and hydrological stability were measured. Grazer populations were quantified to estimate the effect of top-down controls. Nutrient limitation appeared to be the most important control on the diversity and competition outcomes of microalgae and cyanobacteria.

Thaw ponds and lakes varied in their bacterial community structure. A small number of taxa occurred in high abundance and dominated many of the communities. Nevertheless, there were taxonomic differences among different valleys implying some degree of habitat selection. Association networks were composed of a limited number of highly connected OTUs. These "keystone species" were not merely the abundant taxa, whose loss would greatly alter the structure and functioning of these aquatic ecosystem.

Based on our molecular data and performed analyses we found that the gastropods studied represent a comparatively old group that most likely evolved with a constant rate of diversification. However, preliminary data of the SCOPSCO deep-drilling program indicate signatures of environmental/climatic perturbations in Lake Ohrid. We therefore propose that the constant rate observed has been caused by a potential lack of catastrophic environmental events and/or a high ecosystem resilience.

Terrestrial inputs are considered the major driver of longitudinal patterns of nutrient concentration. Yet we show that longitudinal trends result from hydrological mixing with terrestrial inputs and in-stream processes. We challenge the idea that nutrient concentrations decrease downstream when in-stream net uptake is high. Conversely, in-stream processes can strongly affect stream nutrient chemistry and fluxes even in the absence of consistent longitudinal trends in nutrient concentration.

Short summary
Under UVR and stratification,the commensalistic algae-bacteria interaction was strengthened in the high-UVR lake, where excretion of organic carbon rates exceeded the bacterial carbon demand,but did not occur in the low-UVR lake.The greater UVR damage to algae and bacteria and the weakening of their commensalistic interaction found in the low-UVR lake indicates these lakes would be especially vulnerable to UVR. These results have implications for the C cycle in lakes of the Mediterranean region.
