Her talk on the 21st was titiled: "Understanding the Plant Fossil Record, Plant Morphology, and Plant Anatomy is critical in the genomic era". Ana Andruchow-Colombo gave a talk on the 22nd titiled: "Ginkgoaleans at the edge of the Mesozoic: Ginkgoites from the Late Cretaceous Lefipán Formation of Patagonia, Argentina". Ayress Grinage gave a talk on the 21st titled: "Deciphering the Tales of Sabal from the Crypt: Insights from Past Collections" and Teddy gave a talk on the 19th titled: "New reproductive structures of Cunoniaceae tribe Cunonieae from the early Eocene Laguna del Hunco flora, Chubut, Patagonia, Argentina." Congratulations to all the presentors!
Welcome to the lab!
Cesar Galan is a transfer student and will soon start working with Ana on morphological and anatomical features of the Podocarpaceae and Cupressaceae.
Dr. Gandolfo and Teddy Matel participated in the Virtual Midcontinent Paleobotanical Colloquium of 2021. Dr. Gandolfo gave the Keynote talk on June 6th, titled: " Darwin’s 'Damned land': A paleo(neo)botanist’s paradise". Teddy Matel gave a talk on the same day (with co-authors M.A. Gandolfo, E.J. Hernsen, and P. Wilf), titled: "New reproductive structures of Cunoniaceae tribe Cunonieae from the early Eocene Laguna del Hunco flora, Chubut, Patagonia, Argentina."
A new paper is out in Cretaceous Research:
Clyde, W.C., J.M. Krause, F. De Benedetti, J. Ramezani, N.R. Cúneo, M.A. Gandolfo, P. Haber, C. Whelan, and T. Smith. 2021. New South American record of the Cretaceous–Paleogene boundary interval (La Colonia Formation, Patagonia, Argentina). Take a look!
Dr. Gandolfo is giving a workshop for the U.S. Botanic Garden:
Title: The Art of Plant Anatomy: A Botanical Illustration Workshop with Dr. Alejandra Nixon
Description: Have you ever wondered what plants look like on the inside? Explore the beauty and function of plant anatomy in this special botanical illustration series highlighting the inner workings of plant structures. Over the course of four classes, Dr. Alejandra Nixon will show you how to observe and illustrate microscopic views of Stems & Roots, Leaves, Flowers, and Fruits. You’ll use the plant histology slides from Cornell University’s stunning collections to guide your artistic investigation of plant anatomy. After this workshop, you’ll never look at plants the same way again!
Congratulations Teddy! Teddy has won one of the 2021 Botanical Society of America Undergraduate Student Research Awards in support of his work on fossil Cunoniaceae from Laguna del Hunco, Patagonia.
Two new papers will be coming out in rapid succession. One paper in press will be published by the Journal of South American Earth Sciences: Macroevolutionary changes in the fossil plant record: Key examples from the Cretaceous-Paleogene of Patagonia, Argentina. Another paper has been accepted in the International Journal of Plant Sciences: Southern high latitude plant-insect interactions from the Miocene of Tierra del Fuego, Argentina. Both papers were written by Maria A. Gandolfo and Mmaria C. Zamaloa.
A new publication in The American Journal of Botany:
Paleoaltingia gen. nov., a new genus of Altingiaceae from the Late Cretaceous of New Jersey. by Yangjun Lai, Maria A. Gandolfo, William L. Crepet, and Kevin C. Nixon.
The lab welcomes new students
Two new students are going to be working in Dr. Gandolfo's lab this semester:
Zackary Kozma is a sophomore majoring in Biology with a concentration in Ecology and Evolutionary Biology and minoring in Plant Sciences. Zack will be working on the family Sapindaceae.
Rachel Peverly is a sophomore majoring in Plant Sciences with a concentration in Plant Evolution and Diversity. Rachel will be working with Ayress Grinage on Sabal.
New paper published in the International Journal of Plant Sciences:
First South American Record of Winteroxylon, Eocene of Laguna del Hunco (Chubut, Patagonia, Argentina): New Link to Australasia and Malesia by Mariana Brea, Ari Iglesias, Peter Wilf, Eliana Moya, and María A. Gandolfo.
Due to the continuing COVID 19 problems, Dr. Gandolfo's new students will be arriving later than normal to the lab:
Ayress Grinage, a graduate student who is working on Sabal leaf anatomy, will return to the lab in February to continue on her work begun in the last semester.
Teddy Matel, a junior in Plant Sciences concentrating in Plant Systematics and Evolution, will also return in February to continue working on Cunoniaceae from the Early Eocene.
Dr. Ana Andruchopw-Colombo, from Argentina, will join the lab in April. She will be working on the description of the gymnosperm component of the Lefipan Formation.
Also Dr. An Xiaohong, a postdoctoreal associate in Dr. Gandolfo's lab, will continue working on the phytoliths of the Lefipan Formation.
New papers have come out in the American Journal of Botany:
New physaloid fruit‐fossil species from early Eocene South America by Rocío Deanna, Peter Wilf, Maria A Gandolfo. and
52 million years old Eucalyptus flower sheds more than pollen grains. by Maria C. Zamaloa, Maria A. Gandolfo, Kevin C. Nixon.
Dr. Gandolfo announces that the CU-PAC Plant Anatomy Online Lab Manual is now live! It can be found here: http://cupac.bh.cornell.edu/anatomy_manual/PAOnline.html
Dr. Gandolof has three undergraduate students working on projects in her lab. They are:
Colton Poore worked in Dr. Gandolfo’s lab on a silicified endocarp in the Icacinaceae from the early Paleocene of Patagonia, Argentina. He will complete a manuscript by the end of 2019 and it will be his Honors Thesis. He presented the results of his research at Botany 2018 and his poster was selected, among more than 800, for publication.
Jessica Dobler: I am an undergraduate Biology major working on a project along with Camila Martinez that analyzes oak trichomes. We are sampling many species of Latin American Oak trees, and photographing them under the Scanning Electron Microscope, paying special attention to the trichomes. We are then going to analyze and classify the trichome morphology for each species, and perhaps analyze and classify the stomata as well. Hopefully from this data we will be able to establish phylogenetic relationships between oak species, and perhaps in the future we can correlate the data to climate, or other pressures on selection to draw some conclusions about oak tree evolution

Updates to the lab
The Gandolfo lab has moved down the hall from 410 to 406. With this move, Dr. Gandolfo purchased some great new equipment: a Phenom XL desktop SEM and a Nikon flourescence dissecting scope.
