Vegetation history and salinity gradient during the last 3700 years in Pichavaram estuary, India
Jyoti Srivastava Anjum Farooqui S M Hussain
Palaeoclimate, palaeoecological and palaeoshoreline studies were carried out for a 2.5 m deep sediment core deposited since ∼3700 yrs BP in the central part of Pichavaram mangrove wetland, Cauvery river delta. Presently, the study area is dominated by

The rise of the Himalayas governed the Indian Summer Monsoon in Karewa basin during Plio-Pleistocene. A palynological study is presented to delineate the climate-vegetation relationship using an 8.5-m thick fluvio-lacustrine sequence of the Hirpur Formation (2.4–2.1 Ma). Our results suggest that the sediment sequence is mainly comprised of two units, namely, Unit 1 and Unit 2. Unit 1 shows the dominance of sub-tropical to broad-leaf temperate vegetation when mean annual temperature (MAT) was ${\sim}$ 17$^{\circ}$ C and mean annual precipitation (MAP) was 1025 mm. The subsequent increase in sand followed by a thin lignite layer with
$\bf{Highlights}$
$\bullet$ Climate–vegetation relationship is established through a palynological record.
$\bullet$ Unit 1 comprises subtropical to broad-leaf temperate vegetation with warmer mean annual temperature and higher mean annual precipitation.
$\bullet$ Unit 2 comprises colder diatom species and is following cooler mean annual temperature and lower mean annual precipitation.
$\bullet$ A shift of tropical to cool temperate vegetation is related to the rise of the Pir Panjal Mountains, obstructing monsoon.

Carbon assimilation in plants depends on both atmospheric CO$_2$ uptake and internal (non-atmospheric)
CO$_2$. To understand this mechanism in

$\bullet$ The ${\delta}^{13}$C leaf (carbon) and ${\delta}^{15}$N leaf (nitrogen) decreased by ${\sim}$ – 4‰ (– 26.0 to – 30.0‰) and 1.6 to – 0.35‰ in 2018, respectively.
$\bullet$ The intrinsic water use efficiency of
$\bullet$ An alternative process of ‘Alarm Photosynthesis’ seems to be active due to low stomatal conductance in the warmer climate.
