We invite you to join us on an incredible journey through the heart of Ecuador, where a group of adventurous students from Florida Institute of Technology embarked on a life-changing experience as part of the Neotropical Archaeoecology summer field course. Buckle up as we delve into the marvels of nature, indigenous cultures, and unforgettable experiences. Let’s dive right in!

Unveiling the Andes

Our adventure began with a breath-taking visit to the Paramo at Cayambe-Coca National Park. Paramos are high altitude (3000-4000 metres) wet grasslands above the tree line and below the snow line within the equatorial Andes. Our tour guides Patricio and Byron gave us information about the local vegetation, focusing on the Polylepis tree (locally known as “paper tree”), which is unique to this sort of habitat. They also told us about some of the fascinating wildlife that can be seen here, such as the Andean Bear (Tremarctos ornatus) and the Andean Puma (Puma concolor).

We then descended through the cloud forest (3,600–3,400 meters) and lower montane rainforest (3,400–2,500 meters). Across these various habitats, we documented changes in hummingbird abundance and recorded their behaviour at four different feeder points: Guango Lodge, La Brisa, San Isidro Lodge, and Cascada el Hollin. The sheer diversity of hummingbird species left us in awe, and we marvelled at their iridescent feathers and incredible agility.

We explored a waterfall near San Isidro Lodge (https://cabanasanisidro.com), and we were able to observe pre-Inca pottery. At the lodge we also saw a diverse array of bird species, which was delightful! The forest’s nightlife brought us close encounters with a group of nocturnal monkeys, and to our surprise, we stumbled upon a very rare mountain tapir. The following morning we saw a small agouti (a small rodent) prowling around the lodge, and ended our adventures in the cloud forest on a high note.

Mapping Ancient Africa: Scientists – Alfred Houngnon

August 15, 2023
WDG

My name’s Alfred Houngnon, native of Benin Republic in West Africa. I hold an agricultural engineering degree in “Rangeland Management and Conservation” (Abomey-Calavi University). After gaining relevant field experience, I obtained a French Government Bursary to pursue an MSc degree in “Tropical Plant Biodiversity” at Montpellier (France). There, I learned about how to use indicators of past environmental and climatic change to give insights into projected future change.

It was a great scientific experience to participate in-person at the XXI INQUA Congress 2023 in Rome (Italy). This opportunity came under the supervision of William Gosling, and with the support of the Mapping Ancient Africa (MAA) project funded by INQUA’s Palaeoclimate commission (PALCOM). I have been working with Will for a number of years and published a first paper related to this work in 2021; a checklist of vascular plants from a ‘relict’ forest in Benin (Houngnon et al., 2021). A second manuscript is under development and was accepted for poster and oral presentation at INQUA 2023 congress that brought together around 4000 abstracts.

Interview 1: Alfred Houngnon (AGIR)

The bursary from the MAA project allowed me to also attend the MAA Rome workshops held at the Royal Netherlands Institute in Rome (12-13 July 2023). During the workshops, I was trained in two novel approaches to palaeoclimate modeling. The first based on interfacing paleoclimate models through the “pastclim” R package (Michela Leonardi), and the second on reconstructing palaeoclimates on the basis of ancient pollen data using the “CREST” program (Manu Chevalier). The workshops helped me to sharpen the communication of my ideas and in so doing strengthened the manuscript in preparation for submission to an international journal for publication.

The Mapping Ancient Africa (MAA) project has a double session of talks and a poster session at the INQUA congress in Rome 2023. Our session will be on Wednesday 19 July. Unfortunately a number of the originally planned speakers could not make it to Rome due to a combination of not obtaining visas, logistical challenges and ill health. We wish them all well and hope that they will continue to be involved in the project. Further, many thanks to all those who have agreed to step up and give a presentation at a late notice. Below is an updated schedule correct as of Sunday 16 July based on the information contained on the INQUA Rome App; if you are aware of any further problems or changes please let me know ASAP!

If you are at the INQUA Rome congress please come along to our talks and posters in Session 64: Mapping Ancient Africa: Climate, Vegetation & Humans.

Part 1: 08:30-11:00

Giosan et al. When the desert was a lake: Providing context for Homo sapiens development in the northern Kalahari
Chase et al. Paleolakes and socioecological implications of glacial “greening” of the South African interior
Blinkhorn et al. Evaluating refugia in recent human evolution in Africa
Aureli et al. Homo sapiens behaviour and adaptation in East Africa. New evidence from an open-air site in a modern Ethiopian savannah environment: the GOT10 site
Effiom et al. Late Holocene palaeoecological studies at Lake St Lucia, KwaZulu-Natal
Tallavaara et al. Pan-African Climate and Vegetation over the Quaternary and Implications for Human Distribution
Quick et al. Palaeoenvironments of the Cape Floristic Region: New research & current developments

In person attendees (left to right): William Gosling (University of Amsterdam), Busisiwe Hlophe (University of Witwatersrand), Michela Leonardi (University of Cambridge), Soléne Boisard (University of Montréal), Rahab Kinyanjui (National Museums of Kenya), Trevor Hill (University of KwaZulu-Natal), Mathias Vinnepand (Johannes Gutenberg-University of Mainz), Tom Johnson (University of Massachusetts Amherst), Manu Chevalier (University of Bonn), Brian Chase (CNRS: Montpellier), Stefanie Kaboth-Bahr (Free University of Berlin), Markus Fischer (University of Potsdam), Bahru Zinaye Asegahegn (University of Cologne), Alfred Houngnon (AGIR), and Jemma Finch (University of KwaZulu-Natal); present but not in photo Angela Effion (University of Witswatersrand).

A further nine participants were anticipated to attend the workshop but, due to a combination of the non-issue of visas, logistical difficulties and ill health, they were not able to attend at the last moment. These were: Aliyu Adamu Isa (Ahmadu Bello University), George Biddulph (University of St Andrews), Olugbenga Boboye (University of Ibadan), Husna Mashaka (University of Nairobi), Emma Mbua (National Museums of Kenya), Aissatou Thiam Ndong (University of Cheikh Diop, Dakar), Adisa Ogunfolakan (Leventis Museum of Natural History), Alice Paine (University of Oxford), and Lynne Quick (Nelson Mandela University). Some people were able to attend partly online. Some have now made it to Rome and we hope to catch up at the INQUA Rome congress (Session 64) if not before. We hope that all will continue to be involved with the Mapping Ancient Africa project.

The Mapping Ancient Africa workshop took place at the Royal Netherlands Institute in Rome on the 12 and 13 July 2023. Participants engaged with two different approaches to palaeoclimate modelling:

Interfacing palaeoclimate models through the “pastclim” R package. Lead by Michela Leonardi.
Reconstrucing palaeclimate on the basis of ancient pollen data using the CREST program. Lead by Manu Chevalier.

The aim of the workshop was to promote interaction between scientists working across Africa and across disciplines (palaeoclimate, palaeoecology, archaeology, modelling). The plenary session was joined by participants who could not make it to Italy via Zoom. This session was recorded and you can watch it below. In the plenary session outputs from the workshop, the planned special issue of Quaternary International, and the future of the Mapping Ancient Africa project were discussed.

“Plant Ecology & Diversity” & Biogeography

July 6, 2023
WDG

A recent open letter to Wiley from Associate Editors working for the Journal of Biogeography posted by Lucie Zinger and others highlighted a dispute between the editors and the publishers in relation to: (i) the proposed switch of the journal to a pure open access model, (ii) financial barriers to publication, (iii) the proposed increase in throughput of manuscripts to maximise profits, and (iv) the manuscript referral process (see @LucieZinger, read tweet here, dated 28 June 2023). This got me thinking about these issues in relation to the journal that I am most involved with editing which also published papers related to biogeography; Plant Ecology & Diversity.

Plant Ecology & Diversity is the journal of the Botanical Society of Scotland. It is published in association with Taylor & Francis and any profits are split between the publishers and the academic society. To promote diversity and inclusion among authors the journal has a policy of double blind peer review (and has done for many years). Further, there are no publication fees for authors to publish in this journal, however, this does mean that published papers are behind a pay wall. An “Open Access” option is available to all authors for a fee (hybrid model), although the invited “Grubb Reviews” series is automatically published Open Access. Subject Editors and Associate Editors “work” for the journal gratis (for free) and the love of furthering the field.

If you have manuscripts related to biogeography, and prefer this mode of publishing, then please consider the fit of your paper to Plant Ecology & Diversity and send them our way. Or indeed if you have manuscripts related to one of our other key themes:

evolution and systematics,
global change and vegetation dynamics,
environment and plant functioning, and
biotic interactions.

The journal accepts original research articles (c. 7000 words), rapid communications (c. 2500 words), review articles (c. 12,000 words), and perspectives (c. 2500 words). Other options for publishing are of course also available 🙂
