A dynamic subtropical coastal hotspot of benthic foraminifera in the Southeastern Mediterranean indicates early-stage tropicalization
AbstractDue to ongoing ocean warming, subtropical environments are becoming accessible to tropical species. Among these environments are the vermetid reefs of the Southeastern Mediterranean (SEM). In the last decades, these valuable coastal habitats witnessed the proliferation of numerous alien species of tropical origin. Among the meiofauna thriving on these reefs are benthic

A matter of choice: Understanding the interactions between epiphytic foraminifera and their seagrass host Halophila stipulacea
AbstractIn sub/tropical waters, benthic foraminifera are among the most abundant epiphytic organisms inhabiting seagrass meadows. This study explored the nature of the association between foraminifera and the tropical seagrass species H. stipulacea, aiming to determine whether these interactions are facilitative or random. For this, we performed a "choice" experiment, where

Trends in organic matter deposition in the Cretaceous of the eastern Mediterranean: Revisiting and updating the chronology and facies of the Eratosthenes Seamount deposits
AbstractIn this study we revisited the Cretaceous of the Eratosthenes Seamount (ESM) from IODP LEG 160 Hole 967E, updating the chronology, depositional environment, and paleobathymetry of the ESM. Our goal was also to address the spatio-temporal distribution of organic matter and, by comparison with the eastern margins of the Levant Basin, discuss basin-wide controls on its

Petroleum Potential of Cretaceous Source Rocks in the Levant Basin
AbstractSeveral oil shows have been reported from offshore and onshore wells of the Levant Basin, which promoted research and exploration as indicators for potential economic discoveries in the yet unpenetrated Mesozoic interval of the basin. In most cases, no definitive source to oil correlation has been established, advocating the need for the fingerprinting of regional source

The transcriptomic signature of cold and heat stress in benthic foraminifera - Implications for range expansions of marine calcifiers
AbstractGlobal warming permits range expansions of tropical marine species into mid-latitude habitats, where they are, however, faced with cold winter temperatures. Therefore, tolerance to cold temperatures may be the key adaptation controlling zonal range expansion in tropical marine species. Here we investigated the molecular and physiological response to cold and heat stress

Benthic foraminiferal preferences for macroalgal habitats: implications for coastal warming
AbstractConsidering the thermal limits of coastal macroalgae habitats in the Eastern Mediterranean, it is important to study the response of the associated meiofauna in order to better understand the expected feedback of ecosystems to future warming. In this study, we characterized the benthic foraminiferal assemblages of two common types of macroalgae habitats (Turf and

The combined effects of rising temperature and salinity may halt the future proliferation of symbiont-bearing foraminifera as ecosystem engineers
AbstractRising sea surface temperatures and extreme heat waves are affecting symbiont-bearing tropical calcifiers such as corals and Large Benthic Foraminifera (LBF). In many ecosystems, parallel to warming, global change unleashes a host of additional changes to the marine environment, and the combined effect of such multiple stressors may be far greater than those of temperature

Unravelling the evolution of extraordinary long-range planktonic foraminifera species based on image processing analysis
AbstractThe recent growing interest in Late Cretaceous biserial planktonic foraminifera (heterohelicids) has greatly enhanced their use as paleoceanographic and biostratigraphic markers. Pseudotextularia nuttalli, one of the most common cosmopolitan planktonic foraminifera, has an exceptionally long evolutionary range (Turonian-Maastrichtian). The image processing procedure we

Resilience of primary and export productivity in a eutrophic ecosystem following the Cretaceous-Paleogene mass extinction
AbstractThe recovery time of marine productivity following the Cretaceous-Paleogene (KPg) mass extinction varies tremendously with location (hundreds to millions of years), with possible delays in the tropics as compared to higher latitudes. This heterogeneity is based on prevalent oligo- to mesotrophic marine environments. While highly productive eutrophic environments are
