1. Introduction


2. Talks [15 mins for each]


(1). Late Aptian climate changes in South American and its effect on vegetation

Marcelo De Carvalho ( National Museum, Federal University of Rio de Janeiro )

Short abstract: The Cretaceous is generally conceived as one of the warmest geological periods in Earth history. The link between climate and plant distribution will be highlighted on the basis of palynological analyses. The material studied derives from sections drilled through the Aptian sections in northeastern Brazil.


(2). Climate as a driver of regime shifts in the Central Asian steppe-desert

Natasha Barbolini ( Stockholm University )

Short abstract: The arid and highly seasonal steppe-desert biome in Central Asia is today the largest of its kind in the world. It has been shaped by no less than two regime shifts since Eocene times; in both cases, climate emerges as a major driver. Past responses imply that modern Asian steppes are unlikely to recover their unique biodiversity if forced into a new regime by anthropogenically-driven changes.


------ First Round Questions & Biobreak ------ [6-8 min]

(3). Reconstructing palaeoclimates in the Cape Floristic Region, South Africa: a palynological approach

Lynne Quick (African Centre for Coastal Palaeoscience, Nelson Mandela University)

Short abstract: The Cape Floristic Region (CFR) is a key focus area within southern Africa due to its botanical importance in terms of high levels of biodiversity as well as its rich cultural and archaeological heritage. The area is highly sensitive to cycles of regional and global environmental change, and records obtained from the region may provide valuable information regarding past climate variability. Prior to the last decade, few high resolution palaeoenvironmental records were recovered from the region, and therefore its environmental history was previously poorly understood. This presentation summarises some of the most important findings that have emanated from several pollen records generated over the last few years and outlines current and future directions for palynological research in this region.


(4). The expansion and retraction patterns of Tropical Rainforest via the Brazil NE route during the last glacial

Patricia Piacsek ( Universidade Federal Fluminense )

Short Abstract: Vegetation response in NE Brazil during millennial-scale events of the last glacial period.


------ Second Round Questions & Biobreak ------ [6-8 min]

(5). Vegetation and Climate change during recent Holocene in Colombian Caribbean mangroves

Yennifer Garcia ( Universidad Nacional de Colombia )

Short abstract: It presents the main palaeoenviromental changes during last 2000 years in mangrove ecosystems from Colombian Caribbean region.


(6). Pollen records from the wetlands of Majuli Island, and its implication to decipher palaeoflood episodes in northeast India

Swati Tripathi ( Birbal Sahni Institute of Palaeosciences )

Short abstract: The study is the first attempt from any Indian wetland, where palynological data is assessed to understand the flooding histories of the Sakali and Duboi wetlands in the Majuli River Island, a part of the Indo-Burma hotspot. Palynological analyses of surface soil samples from these wetlands were carried out in order to explore the flooding histories of this island. The Correspondence analysis (CA) successfully discriminated the samples from the two wetlands and also marked strong correlations between flood indicators extra-local taxa with the samples of the Sakali wetland and local arboreal elements with the Duboi wetlands.
