Department of Biology 26 Summary The Department of Biology at the University of Louisiana at Lafayette took its current form in the late 1980s, with the merger of the Biology and Microbiology Departments. In Spring of 2019, the department has 28 professorial faculty members, 6 emeritus faculty members, and 7 instructors. Almost all professorial faculty members are active in research and serve as graduate faculty. Our graduate programs are also supported by 8 adjunct faculty members; their affiliations include the United States Geological Survey, the National Oceanographic and Atmospheric Administration, and the Smithsonian Institution. In this report, we summarize research accomplishments of our departmental faculty since 2013. The report is focused on our research strengths; however, faculty members have also been awarded considerable honors and funding for educational activities. We also briefly summarize the growth and size of our degree programs. Grant Productivity From 2013 through 2018, the Department of Biology has secured over 16 million dollars of new research funding (the total number of dollars associated with these grants, which are often multi- institutional, is considerably higher). Publications The faculty has a strong record of publication, with 279 papers published in peer-reviewed journals in the last 5 years. An additional 30 papers were published in conference proceedings or other edited volumes. Other Accomplishments Other notable accomplishments between 2013 and 2018 include faculty authorship of five books and edited volumes. Faculty members have served as editors, associate editors, or editorial board members for 21 different journals or as members of 34 society boards or grant review panels. They presented 107 of presentations as keynote addresses or invited seminars. -

Bernt Maxwell J. Bernt , Aaron H. Fronk , Kory M. Evans 2 [email protected] and James S. Albert From a study of morphological and molecular datasets we determine that a species originally described as Sternarchogiton preto does not form a monophyletic group with the other valid species of Sternarchogiton including the type species, S. nattereri. Previously-published phylogenetic analyses indicate that this species is sister to a diverse clade comprised of six described apteronotid genera. We therefore place it into a new genus diagnosed by the presence of three cranial fontanels, first and second infraorbital bones independent (not fused), the absence of an ascending process on the endopterygoid, and dark brown to black pigments over the body surface and fins membranes. We additionally provide Submitted November 13, 2019 a redescription of this enigmatic species with an emphasis on its osteology, and Accepted February 2, 2020 by provide the first documentation of secondary sexual dimorphism in this species.

EXECUTIVE SUMMARY ENGLISH: This study sought to provide insight into the life of Apteronotus rostratus, a species of weakly electric fish encountered in the rivers of Panama. Weakly electric fish have had their ability to actively generate electricity to sense their environment extensively studied in the laboratory, but little is known about their lives in the wild. A suitable study site was found at Piriati, in the Bayano region, where numerous Apteronotus rostratus were found in the river on an initial field outing. In order to fill the knowledge void about Apteronotus rostratus in the wild, four 200m transects were conducted in the Piriati river, and the location, habitat and frequency of every individual was taken (for a total of 240 Apteronotus rostratus sampled). -

We reassessed the type specimens of the two Lithophyllum species historically reported from offshore communities in North Carolina, L. intermedium with a Caribbean Sea type locality and L. subtenellum with an Atlantic southern France type locality, using scanning electron microscopy images and diagnostic rbcL sequences. Neither of the sequences generated from the type specimens matched rbcL sequences from contemporary specimens collected from subtidal North Carolina epibenthic communities. On the basis of analyses of rbcL and other loci (psbA, UPA, and COI), we instead found L. atlanticum, recently described from Brazil, and L. searlesii sp. nov. from Onslow Bay, North Carolina. These sequence data show that L. atlanticum is related to northeast Pacific species, whereas L. searlesii is related to Mediterranean species.

AND MILLAR A.J.K. 2009. The genus Amphiroa (Lithophylloideae, Corallinaceae, Rhodophyta) from the temperate coasts of the Australian continent, including the newly described A. klochkovana. Phycologia 48: 258–290. DOI: 10.2216/08-84.1 Studies of Amphiroa (Lithophylloideae, Corallinaceae, Rhodophyta) from the temperate coasts of Australia provide new evidence that differences in tetrasporangial conceptacle pore canal anatomy are diagnostically significant in delimiting species within the genus. Differences in overall morphology and genicular anatomy are also reliable for delimiting species. These data are supported by examination of relevant type specimens. Four species occur in temperate Australian waters. Three (Amphiroa anceps, Amphira beauvoisii, and the newly described Amphiroa klochkovana) occur in southeastern Australia, and three (A. anceps, A. beauvoisii,andAmphiroa gracilis) occur in southern and southwestern Australia. Comparisons of A. beauvoisii and A. anceps have shown that they cannot be separated at species level morphologically but clearly differ in tetrasporangial conceptacle pore canal anatomy. This has important flow-on implications concerning specimen identification, reported geogeographic distribution and putative heterotypic synonymy of the two species. Relevant historical data, a species key and a synoptic description of Amphiroa also are included. -

This group (ca. 200 species) has originated in South Intergenic spacer America, and six species colonized the Central American Isthmus. Here, we assembled the complete mi- Mitogenome tochondrial genomes (mitogenomes) for three Central American electric fishes (i.e. Sternopygus dariensis, Next generation sequencing Brachyhypopomus occidentalis, and Apteronotus rostratus), and, based on these data, explored their phylogenetic Panama position among Gymnotiformes. The three mitogenomes show the same gene order, as reported for other fishes, with a size ranging from 16,631 to 17,093 bp. We uncovered a novel 60 bp intergenic spacer (IGS) located between the COII and tRNALys genes, which appears to be unique to the Apteronotidae. -
