We are interested in what the species of ferns and lycophytes are and where they occur—something often poorly known for tropical species—and the evolutionary relationships among the species. We generate phylogenetic trees based on DNA sequences that show how the species are related and use the trees as a framework for answering questions about character evolution, biogeography, and evolutionary processes.
Micromorphology of DFW Metroplex Fern and Lycophyte Spores
This article was written by Ivan Rosales, 2019 BRIT Summer Intern and student at University of Texas at Arlington. Ivan interned with Dr. Alejandra Vasco , working on fern diversity and anatomy. Who Would Have Thought to Look? The Micromorphology of DFW Metroplex Fern and Lycophyte Spores Anthony van Leeuwenhoek was a scientist from the Netherlands who discovered and described for the first-time bacteria, microscopic protists, sperm cells, blood cells, microscopic nematodes, rotifers, and much more. Even centuries after Leeuwenhoek first looked at a drop of pond water through his early microscope invention and saw microscopic creatures, people still asked, “Who would have thought to look?” I asked myself the same question after seeing my first mounted fern spore using BRIT’s Scanning Elect...
