Botanical Superlatives from the 2024 Field Season

The initial results are in and the most abundant tree in the botanical plots from the 2024 field season is a tie between Astrocaryum mexicanum and Pouteria sapota – both totalling 209 stems above 5 cm dbh (diameter at breast height). Meanwhile, the species with the highest total basal area was Dialum guianense.

Astrocaryum mexicanum (pictured) is a palm with spines that have pricked more than a few tropical researchers. The palm heart can be eaten, but its uses are not as well-documented as the other two species that came out on top. Pouteria sapota, also known as mamey, has large, nutrient-rich fruits. They are a well-known food source in these tropical forests. Dialum guinanense, commonly known as ironwood, also has edible fruits, but it is best known for its dense wood that has been used for construction since prehistoric times.

Joe presents Amazonian palaeoecology to HumAnE

Bladen postdoc, Joe Hirst, presented to the University of Exeter Centre for Human-Animal-Environment Bioarchaeology (HumAnE). His presentation titled, “Domestication of Amazon Rainforest by the pre-Columbian Casarabe Culture,” reviewed the palaeocology in the Llanos de Moxos region in Bolivia, part of his PhD research.

Sediments in Process

Sediments retrieved during the 2024 field season will be analysed for pollen, charcoal, and phytolith content, along with their geochemical composition. These components reveal the environments through time present in the Bladen project area.

This week, the lab at the University of Exeter is up and running for macrocharcoal analysis. This dataset will reveal fire incidence through time. More soon!

Bladen Legacy at ECTE

Bladen Legacy team members attended the 8th European Conference of Tropical Ecology from 24 to 28 February 2025 in Amsterdam. Sara Eshleman presented “Sensing Maya legacies in Central American forests” with Mark Robinson as a co-author. Mark presented “Human legacy on a Belizean Forest” with Sara and Keith Prufer as co-authors. Additionally, new postdoc, Joe Hirst, presented “Modelling maize agriculture by the pre-Columbian Casarabe Culture of Bolivia using palaeoclimate reanalysis and agent-based modelling” based on his prior research.

All team members engaged with new and existing colleagues around human-environment interactions in the tropics, tropical palaeoecology, and tropical ecosystem dynamics.

Welcome to the Team: Joe Hirst

Dr. Joseph Hirst is joining the Bladen Legacy team as a palaeoecology postdoc based in Exeter. Joe earned his PhD from the School of Archaeology, Geography, and Environmental Science at the University of Reading. Joe specializes in pollen analysis and agent-based modelling, and will be applying these techniques to the Bladen project.

Big Trees in Focus: Ceiba

The Bladen Legacy team was astounded by the number and size of big trees during the 2024 field season. These trees will be the focus of directed work in the upcoming 2025 field season. One particularly astonishing specimen was a large ceiba tree. Ceiba trees are important to Maya mythology and have a strong human connection in that manner, but they also grow relatively quickly so further testing is necessary to ascertain whether the ancient Maya in the Ek Xux valley saw this same tree.

Click the point cloud image below to explore the lidar point cloud around the ceiba. The photos demonstrate the size of this Ceiba relative to different team members.

Jose Mes in National Geographic Traveller

Project associate, Jose Mes, was featured in the December issue of National Geographic Traveller. He and his wife, Hilda, offer a Maya food experience in their home and farm in Santa Cruz Village. Field team members have been treated to Hilda’s cooking and we highly recommend the experience.

Join the Bladen Legacy Team as a Palaeoecology or Palaeobotany Postdoc

We are hiring two postdoctoral research associates to join the Bladen Legacy team. One of the University of Exeter-based postdocs will lead palaeoecological analysis and interpretation, particularly for pollen and charcoal. The other will lead the palaeobotany analysis and interpretation, especially for phytoliths. These positions will work together and with the broader team towards understanding vegetation change and plant use through time in the Bladen Project area.

Find more information and apply by 6 January 2025 here for the palaeoecology post and here for the palaeobotany post.

Faunal Remains Practicum with the HumAnE Centre

Dr. Mark Robinson and Oscar Wilkinson, an MSc Bioarchaeology: Zooarchaeology student, led a hands-on practicum for the HumAnE Bioarchaeology Centre around a Bladen faunal assemblage. Mark started with a brief presentation titled “Food production in the Mesoamerican neotropics through the Holocene.” Then HumAnE members engaged with tropical fauna from the rock shelter contexts and developed an initial classification of the material.

Collaboration with LASTJourney in Serranía de La Lindosa, Colombia

Dr. Mark Robinson and Sara Eshleman were invited to partake in an abbreviated field season in the Serranía de La Lindosa, Colombia with the LASTJourney project. The stunning rock shelter sites contain evidence of early peopling of the tropical Americas, an interesting corollary to the Bladen rock shelters. The fieldwork centred on digitally documenting rock art panels and collecting pigment samples to determine the age of the artwork.
