In the 4th edition of our “Amsterdam Paleoecology Club”(APC), we discussed ‘A 6900-year history of landscape modification by humans in lowland Amazonia’ by Bush et al. (2006)1. The high-resolution record presented in this paper shows impressively that what we might perceive as native rainforest today could rather be a since a long time actively modified landscape.
The chronology from Lake Sauce (Peruvian Andes) suggests a continuously forested landscape under significant anthropogenic impact over the last 6900 years. Indicators of human activity are taken to be the varying presence of crop pollen (Zea mays) throughout the record, combined with the continuous occurrence of charcoal. Two extra-large fire events are dated at c. 6700 and between 4500-4230 cal BP, probably enhanced by the relatively drier climate of the mid-Holocene. However, it is not clear yet if human actions formed a response to climate change or were part of social and cultural changes.
We are currently looking for a new representative to join the British Ecological Society (BES) Education and Careers Committee (ECC) of which I am currently the chair. I have been involved with the BES for may years first attending a conference in 2000 (Warwick University), running the Tropical Ecology special interest group (2006-2009), as an ordinary member of council (2010-2014), and chairing the ECC (2014-2020). Throughout my envolvement with the BES I have had positive experiences and enjoyed contributing to a society that can get things done. Since I have been involved with ECC we have launced under-graduate and A-level summer schools, introduced a mentoring scheme for acadmices, and helped to encourage academics to engage the public with science. If you are interested in helping us to develop the activity of the society please consider joining us!

I recently joined the editorial board of Plant Ecology & Diversity at the invitation of editor-in-chief Laszlo Nagy (University of Campinas, Brazil). The journal focuses on ecological and evolutionary issues within plant biology with broad themes covering biodiversity, conservation and global change. Furthermore, I think this is a particularly interesting journal to be involved with because of its option for double-blind peer reviews, commitment to providing a platform for ‘negative results’ and ‘repeat experiments’, and its open access Grubb Review series (Nagy & Resco de Dios, 2016); which already includes many significant articles, including: Ashton (2017), Barbeta & Peñuelas (2016), Grubb (2016), Körner (2018), Valladares et al. (2016), and Wilkinson & Sherratt (2016). In addition to the invited Grubb Reviews the journal publishes: research articles, short communications, reviews, and scientific correspondence. My role on the editorial board will be to cover submissions related to tropical palaeoecology and biogeography. So please consider submitting to Plant Ecology & Diversity if you have some exciting new research or ideas that you think would be appropriate.
