Hello, and happy new year! In this blog post I’d like to briefly tell you about my first paper that was accepted and published in the journal Quaternary Research in late 2017. It’s entitled “Impact of mid- to late Holocene precipitation changes on vegetation across lowland tropical South America: a paleo-data synthesis” and can be found here.
In late 2016, Frank was approached by Mark Bush who wanted to prepare a collection of papers for a ‘special issue’ to honour the lives of two prominent palaeoecologists, Prof. Paul Colinvaux (1930-2016) and Prof. Daniel Livingstone (1927-2016). Both Paul and Daniel were leading figures in tropical palaeoecology, with Paul focusing predominantly on tropical South America and Daniel in tropical Africa. Throughout their careers, they were at the forefront of much of the breakthroughs in tropical palaeoecology, as well as inspiring and training many graduate students to create an international legacy of palaeoecologists. More can be read about their amazing careers in Mark Bush and Will Gosling’s tribute article: “In search of the ice age tropics, a tribute to Prof. Daniel Livingstone and Prof. Paul Colinvaux”.

Given the focus as Paul and Daniel’s careers, the special issue was to focus on South American and Africa palaeoecology. Frank suggested that I take this opportunity to write a paper to submit to this special issue on some work I had completed previously, synthesising existing palaeoecological data from across tropical South America from the mid-Holocene to the present. So that is what I did! Continue reading
The latest edition of the Past Global Changes (PAGES) Magazine was published yesterday, on the theme of ‘Sustaining Earth’s Biodiversity’, and it features three contributions from the TPRG team.
The sites discussed in Maca and Bronwen’s article, and their main plant species
The first, by Macarena and Northumbria University’s Bronwen Whitney, looks at how palaeoecology can shed light on the legacies of pre-Columbian people in Latin America’s modern ecosystems. It highlights Maca’s research on southern Brazil’s unique and ancient Araucaria forests (which has been part of the Jê Landscapes project, and which I’m continuing for my PhD), as well as Mayan breadnut palms in central America, and the chocolate forest islands and ice-cream bean cultivation of south-western Amazonia. It’s well worth a read, as are the research papers it discusses.
Heather also has two contributions in a mini-section reflecting on the PAGES Young Scientists’ Meeting 2017, an event she’s blogged about previously here (Palaeo-science in the Pyrenees). Her first article addresses the whys and (perhaps more importantly) hows of effective communication for palaeoscientists. Her second – equally important and closely linked – discusses the challenges of communicating the societal relevance of palaeo research, especially to funders and policymakers. Communicating research and its relevance is essential, and the insights and suggestions in these articles should be helpful starting points when considering it.
If you’ve got any questions or comments about the pieces, you can get in touch with Maca and Heather on twitter: @DrMacarenaLC and @HeatherPlumpton. The whole magazine edition can be read or downloaded here.
The Jê group: Farmers and sedentary
This time, written by scientific journalist Marcos Pivetta, this article covers what has been discovered so far by the archaeological research within the project and gives a first glance of what has been found from the palaeoecological research performed by Macarena L. Cárdenas and Frank Mayle.
