The Spratly Islands are located in a vast area with numerous coral reefs the South China Sea within highly biodiverse Indo-Pacific region. Benthic foraminifera were investigated from two unstudied, remote atolls: Louisa Reef (LR) and Royal Charlotte (RC). These atolls about 250 kilometers off Brunei Darussalam, situated at northern coastline of Borneo. We compare diversity distribution benthic these those reported shallow water setting Brunei. Environmental conditions nearshore is very...
The majority of soil carbon resides in mineral-associated organic matter (MAOM) most soils. MAOM is assumed to be relatively inert environmental change because it protected from microbial activity thus contributing substantially storage. However, plants and associated microbes may destabilize through mineral dissolution exchange reactions the rhizosphere, potentially causing loss. Here, we quantified magnitude destabilization rhizosphere response extreme precipitation dynamics expected with...
Roots are presumed to be key controls on anoxic microsites, which partially regulate nutrient availability and the fate of carbon contaminants in soils. However, how root activity interacts with edaphic factors microsite formation is poorly understood. Here, we sought define exudation soil texture alter oxygen dynamics around a model plant root. We used reverse microdialysis deliver 13C-labelled exudates mesocosms two distinct textures. Over course three diurnal cycles, mapped...
Isotopic compositions of marine sediments and fossils have been investigated from northern basins the Mediterranean to help constrain local oceanographic climatic changes adjacent uplifting Alps. Stable C O isotope benthic planktonic foraminifera Umbria‐Marche region (UMC) an offset characteristic for their habitats in composition mimic global changes, suggesting that regional conditions climate carbon cycle were controlled by changes. The radiogenic these fossil assemblages allows...

Neogene marine deposits of North Borneo are locally very rich in fossils that provide glimpses into the past biodiversity. However, dating these onshore sediments with biostratigraphy is often hampered by lack and/or poor preservation state index fossils. Therefore, fossiliferous sites were targeted strontium isotope stratigraphy (SIS) to obtain higher precision relative dating. Well-preserved macrofossils screened using a multidisciplinary approach, and 87Sr/86Sr ratios most pristine...
Abstract. The Middle Eocene Climatic Optimum (MECO) is a global warming event mainly recognized in the marine domain and described less terrestrial environment. Here we present comprehensive geochemical record of MECO from Escanilla Formation, fluvial sedimentary succession southern Pyrenees, Spain, based on suite sampled paleosols, stromatolites, pedogenic nodules. Our multiproxy approach involves using carbon oxygen stable isotope compositions to identify regional preservation MECO,...
The lower Miocene Pirabas Formation in the North of Brazil was deposited under influence proto-Amazon River and is characterized by large changes ecological niches from early onwards. To evaluate these changes, elasmobranch fauna fully marine, carbonate-rich beds investigated. A diverse with 24 taxa sharks rays identified dominant groups being carcharhiniforms myliobatiforms. This faunal composition similar to other assemblages proto-Carribbean bioprovince. However, has unique features...
Abstract. Chondrichthyan teeth (sharks, rays, and chimaeras) are mineralized in isotopic equilibrium with the surrounding water, parameters such as water temperature salinity can be inferred from oxygen composition (δ18Op) of their bioapatite. We analysed a new chondrichthyan assemblage, well bony fish (Pycnodontiformes). All specimens Kimmeridgian coastal marine deposits Swiss Jura (vicinity Porrentruy, Ajoie district, NW Switzerland). While overall faunal generally consistent conditions,...
