Summary module description:

This module aims to unravel the long-term (multi-millennial scale) history of tropical rainforests using a range of complimentary approaches and disciplines – e.g. palaeoecology, archaeology and anthropology.  This inter-disciplinary perspective integrates physical and human geography, ecology, and archaeology.  The module focuses on tropical Latin America and revolves around several key questions: 1) What have been the interrelationships between climate change, human land use (e.g. burning and agriculture), and tropical forest ecosystems through the Holocene, i.e. the last ca. 11,000 years?  2) What is the origin of current patterns of biodiversity?  3) What are the implications of this historical perspective for conservation policy and understanding the fate of tropical forests over the 21st century?  4) To what extent have past cultures/civilisations been constrained by, or benefited from, their tropical surroundings and why did they collapse?

Aims:

To learn the principles and applications of tropical palaeoecology as a tool for understanding the relationship between tropical ecosystems, climate change, and human land use over millennial to Quaternary time scales, and the relevance of this long-term perspective for current debates concerning sustainability, resilience, conservation, and climate change.

Assessable learning outcomes:

By the end of this module, it is expected that you will have:

• a systematic understanding of knowledge, and a critical awareness of the underlying principles, methods, and applications of different techniques commonly employed in tropical palaeoecology (pollen analysis, phytoliths, charcoal, and stable carbon isotopes)


• a comprehensive understanding and practical expertise in techniques of tropical pollen identification, analysis and data presentation


• originality in the application of knowledge, together with a practical understanding of how established techniques of research and enquiry are used to understand the contribution that palaeoecological data can make toward tropical plant ecology and conservation policy


• the ability to critically evaluate current research and advanced scholarship in the discipline via key published literature in tropical palaeoecology


• in depth understanding of the relevance of millennial-Quaternary-scale palaeoenvironmental time series for understanding the underlying drivers and impacts of present and future environmental change

Additional outcomes:

Students will become proficient in microscopy; appreciate the value (and challenge) of integrating different approaches, techniques and philosophies across a range of disciplines (e.g. biology, archaeology, geography/geology); critical thinking, constructing/testing hypotheses, and developing scientific arguments; team-work, debating skills, and effective written and oral communication of ideas and findings.  Students will gain first-hand experience of tropical plant species via a 1-day guided trip to Kew Gardens.

Outline content:

Lecture content includes: the principles and applications of key palaeoecological techniques (fossil pollen, phytoliths, charcoal, stable carbon isotopes) used for reconstructing the long-term (millennial-Holocene scale) histories of terrestrial tropical ecosystems (tropical forests and savannas), drawing upon case studies from the Neotropics; the implications of these palaeovegetation reconstructions for understanding tropical ecosystem ecology, carbon cycling, past climate change, and past human land use; the synergistic relationship and interactions between tropical ecosystems, climate, fire, and human societies over millennial-Holocene time scales; relevance of long-term fossil pollen records for testing Earth System models, predicting ecosystem response to future climate change, and conservation policy;  contribution of a palaeoecological perspective for understanding concepts such as vulnerability/resilience, stability/instability, pristine/anthropogenic, rates of change, thresholds, ecosystem services etc, with respect to tropical ecosystems.

Microscope-based practical classes will cover: the identification of pollen from tropical rainforest, dry forest and savannah taxa; analyses of fossil pollen assemblages from lake/bog sediment cores to reconstruct millennial-Holocene scale vegetation histories.

Global context:

In addition to a range of temporal scales from millennial to Holocene, spatial scales will range from local to regional to global.  Most case studies in the lectures will be drawn from ecosystems in the Neotropics – which are globally important in terms of biodiversity, carbon cycling and climate/hydrology. 

Brief description of teaching and learning methods:

The module comprises 12 lectures (each lasting 1 hour) and 9 hours of laboratory-based practical work (3 sessions, each lasting 3 hours).  Students will be taught microscopy skills and fossil pollen identification.  In addition to the classroom and laboratory based teaching, the students will attend a guided one-day field trip to Kew Gardens to familiarise themselves with tropical plant species (8 hours).
