Mark Bush and I are proud to announce that a tribute to Prof. Daniel Livingston and Prof. Paul Colinvaux has recently been published in Quaternary Research. Dan and Paul were both pioneers of tropical pal(a)eoecology and both died in the spring of 2016 . To mark their passing Mark and I have guest edited ten new papers on palaeoecology drawn from researchers, and regions, of the tropics in which Dan and Paul worked (Bush & Gosling, 2018). We would like to thank Quaternary Research Senior Editor Derek Booth for giving us this opportunity and assisting greatly in the process of compiling the manuscripts. We would also like to thank all to contributing authors for their hard work and dedication to the project. We hope that you will enjoy reading the manuscripts and find them a fitting tribute to the life and work of these two great researchers.

Since being appointed as an Associate Editor of Vegetation History & Archaeobotany last year I have the pleasure of working on a number of exciting and interesting manuscripts from the tropics. I am particularly delighted that the first of these (Astudillo, 2018) has now been published. I particularly liked this manuscript because of: (i) the close relationship that was shown between the historical and fossil records, and (ii) the clear signal shown from working on a island system. This linkage is something I have been thinking about in my own research on Mauritius recently (Gosling et al., 2017) and is, I believe, particularly valuable to do because it demonstrates the validity of techniques to track human activity when applied in contexts without historical documentation. The impact of people on the Galapagos is shown by Astudillo (2018) from investigation of multiple proxies (charcoal, phytoliths and macrofossils) to build up a comprehensive picture of human impacts on one of the most famous places for biodiversity on Earth. Hopefully this study is just the start of investigations into past human impacts on the Galapagos islands, and I hope that you enjoy reading the manuscript!
On Jan 1, 2018 I (Crystal McMichael) get to ring in the New Year in the best way possible by heading off to the tropics to do fieldwork! And this time I get to take two students with me. Britte Heijink and Veerle Vink are both in the Biological Sciences MSc program (Ecology and Evolution track), and they are going to work on research projects that are associated with a recent grant that I was awarded through the Smithsonian Tropical Research Institute CTFS-ForestGEO Research Grants Program.
Job: Post-doctoral researcher in Neotropical Palaeoecology
Location: Institute for Biodiversity & Ecosystem Dynamics, University of Amsterdam
Duration: 3 years
Deadline for applications: 15 January 2018
We are seeking to recruit a Neotropical palaeoecologist to join the recently funded “The past peoples of Amazonia: Assessing ecological legacies” project (PI Dr. Crystal McMichael, funding NWO, based within the Department of Ecosystem & Landscape Dynamics). The project aims to reconstruct cultural histories from lake sediments in northwestern Amazonia, and link past human activities with modern ecological observations. The project involves analyzing microfossils (including pollen, phytoliths, and charcoal), and the development of a transfer function that estimates past human impacts in tropical forest systems.
We are particularly looking for a candidate with expertise and experience, in:

Focus on Global Ecology, including: global biodiversity patterns and ecosystem functioning, human impacts on biodiversity, biogeography of species interactions, and/or global changes in ecosystems, biodiversity and ecosystem services.

The second and third weeks of the Environments Through Time course at the University of Amsterdam has focused on obtaining practical experience of developing chronologies, analyzing multi-variate data-sets, and conducting time series analysis. The focus of the course has been on Quaternary environmental change, however, the skills learnt can be applied to almost any time-scale so long as you have time control points you want to tie together, and multiple things you can track changing through that time.
Over the two week period the students worked on a previously published paper that they had selected that contains: (i) chronological information (at least 3 control points), and (ii) multiple variables that change through the time series (at least 9 variables). In week two they deconstructed the chronologies and generated their own revised versions. For example students have (re-)calibrated radiocarbon dates, made different decisions on dates to include/exclude, and used different approaches to constructing the age vs. depth model, e.g. contrasting linear point-to-point vs. Bayesian methodologies. In week three they have taken the data-set(s) associated with their paper and re-evaluated it in light of the revised chronologies using cluster analysis, ordination techniques, and wavelets.
Through this exercise students have gained experience of how to critically assess scientific literature and gained an appreciation of where re-analysis of data-sets can (and cannot) make a difference. Personally I have be delighted with the high level of engagement and enthusiasm for the material and have been excited to have a chance to delve into literature that I would not otherwise be aware of.

The first, ever, week of the Environments Through Time course at the University of Amsterdam has just finished. The course sits within the MSc Biological Sciences (Ecology & Evolution) and MSc Earth Sciences (Geo-ecosystem Dynamics) but is also avaliable to other masters students. In the first week we have thought about four main topics:
The week was completed with each student giving a three (3) minute presentation of their favourite paper. The papers presented ranged from the extinction of giant sharks, through forest-savannah transitions, to how climate change thwarted Ghengis Kahn. Next week we continue by disecting how chronologies are constructed.
