Are wing contours good classifiers for automatic identification in Odonata? A view from the Targeted Odonata Wing Digitization (TOWD) project

True Labels and Predicted Labels.

In recent decades, a lack of available knowledge about the magnitude, identity and distribution of biodiversity has given way to a taxonomic impediment where species are not being described as fast as the rate of extinction. Using Machine Learning methods based on seven different algorithms (LR, CART, KNN, GNB, LDA, SVM and RFC) we have created an automatic identification approach for odonate genera, through images of wing contours. The training population is composed of the collected specimens that have been […]

Odonata Collections and Databases in Dragonflies & Damselflies: Model Organisms for Ecological and Evolutionary Research

The Odonata community has embraced the benefits afforded by the digital age to access specimens, promote and disseminate data, engage with an ever-growing community of enthusiasts, and answer big questions. Global databases offer the capacity to move beyond simple catalogs, link data and data providers, and create a unified and engaged community. There are millions of odonate specimens currently housed in institutional and private collections, with relatively few digitized and/or imaged. This chapter addresses approaches to data capture, including best […]

Diversity of Nearctic Dragonflies and Damselflies (Odonata)

A new paper in Diversity, authored by a team of international collaborators that was headed up by Dr. John Abbott (Director of The University of Alabama’s Department of Museum Research and Collections) and Dr. Cornelio Bota Sierra (Postdoctoral Research, The University of Alabama Museums) about the Diversity of Nearctic Dragonflies and Damselflies has been published.
