curriculum vitae
Dr. Arce H. is interested in systematics and evolution of catfishes. She is researching the evolution of morphological traits across Siluriformes and wants to establish the ontogenetic origin and development of catfish bones in order to test the validity of homologies across the order. She specializes in the taxonomy and systematics of Doradidae (thorny catfishes) through the development of various projects. She has reviewed and validated genera and species within the family, and described two new species and published a taxonomic revision of the genus Nemadoras. She studied the evolution of the family, built a molecular phylogeny for it, and is working toward a total evidence analysis of the family that includes osteological and myological characters.
She is currently studying the different results provided by molecular and morphological phylogenies to explain relationships between North American and Asian catfishes. She is utilizing tools provided by Morphobank to gather and analyze morphological evidence that support the sister relationship between Ictaluridae and Cranoglanididae. Her research also aims to characterize and seek resolution for the phylogenetic placement of North American fossils Hypsidoris, Rhineastes, and Astephus. She is developing new crowd sourcing tools to allow non-specialists to score morphology for tree-building.
Her research at Stony Brook University is supported by a National Science Foundation Grant to Dr. Maureen O’Leary through the Assembling, Visualizing and Analyzing the Tree of Life.
