title: Grassbase India

description: The grassbase_india_2025_ver1 dataset includes a list of grass species present in different districts of India (barring a few in the union territories of Jammu & Kashmir), compiled from various national and regional floras. The dataset additionally contains information on the subfamily, life history (annual vs perennial) and photosynthetic pathway (C3 vs C4) of each species as reported in the floras. In cases where information on the photosynthetic pathway was not reported in the floras, data were obtained from Osborne et al., (2014). Each district in our dataset has been assigned a biogeographic zone based on the biogeographic classification of the Indian subcontinent by Rodgers et al. (2002). In cases where the district spans multiple zones, the district has been assigned the biogeographic zone that covers the maximum area of the district. In total, the dataset includes district-level distribution information for 1121 grass species belonging to 249 different genera.<i>Variables included in grassbase_india_2025_ver1 dataset</i>Sr. no.State: Name of the StateDistrict: Name of the districtSubfamily: Subfamily of the speciesWFO.accepted.name: Accepted name of the species retrieved using the <i>‘WorldFlora’</i> package in R as per the taxonomic backbone static version dated March 2023Life.history: Life history of the species (annual, perennial or unknown)Photosynthetic.pathway: Photosynthetic pathway of the species (C3, C4, C3/C4 or unknown)Biogeozone: Biogeographic zone as per Rodgers et al., (2002.

title: Stable carbon isotope ratios of alkane of IODP Hole 302-M0004A

description: The Palaeocene/Eocene thermal maximum represents a period of rapid, extreme global warming approx ~55 million years ago, superimposed on an already warm world (Zachos et al., 2003, doi:10.1126/science.1090110; Bowen et al., 2004, doi:10.1038/nature03115; Thomas et al., 2002, doi:10.1130/0091-7613(2002)030&lt;1067:WTFFTF&gt;2.0.CO;2). This warming is associated with a severe shoaling of the ocean calcite compensation depth **4 and a &gt;2.5 per mil negative carbon isotope excursion in marine and soil carbonates (Zachos et al., 2003, doi:10.1126/science.1090110; Bowen et al., 2004, doi:10.1038/nature03115; Thomas et al., 2002, doi:10.1130/0091-7613(2002)030&lt;1067:WTFFTF&gt;2.0.CO;2; Zachos et al., doi:10.1126/science.1109004). Together these observations indicate a massive release of 13C-depleted carbon (Zachos et al., doi:10.1126/science.1109004) and greenhouse-gas-induced warming. Recently, sediments were recovered from the central Arctic Ocean (Backman et al., 2006, doi:10.2204/iodp.proc.302.2006), providing the first opportunity to evaluate the environmental response at the North Pole at this time. Here we present stable hydrogen and carbon isotope measurements of terrestrial-plant- and aquatic-derived n-alkanes that record changes in hydrology, including surface water salinity and precipitation, and the global carbon cycle. Hydrogen isotope records are interpreted as documenting decreased rainout during moisture transport from lower latitudes and increased moisture delivery to the Arctic at the onset of the Palaeocene/Eocene thermal maximum, consistent with predictions of poleward storm track migrations during global warming (Backman et al., 2006, doi:10.2204/iodp.proc.302.2006). The terrestrial-plant carbon isotope excursion (about ~4.5 to ~6 per mil) is substantially larger than those of marine carbonates. Previously, this offset was explained by the physiological response of plants to increases in surface humidity (Bowen et al., 2004, doi:10.1038/nature03115). But this mechanism is not an effective explanation in this wet Arctic setting, leading us to hypothesize that the true magnitude of the excursion - and associated carbon input - was greater than originally surmised. Greater carbon release and strong hydrological cycle feedbacks may help explain the maintenance of this unprecedented warmth.of this unprecedented warmth.

title: Distribution of ostracod species at IODP holes 347-M0063C, 347-M0063D and 347-M0063E

description: A total of 173 sediment samples from the upper 45 mbsf were processed for ostracod analysis at IODP site M0063. Ostracods abundance was very low. All abundances are expressed as single ostracod valves.Additionally, organic Carbon data are shown.For Site M0063 due to sediment expansion, mbsf depths were converted into adjusted mbsf (ambsf), and the latter into adjusted mcd (amcd) [Obrochta et al., 2017]. Ambsf scale is used for Holes A and B; amcd scale for Holes C, D and E.
