New Algal Species Records for Great Smoky Mountains National Park, with an Annotated Checklist of all Reported Algal Taxa for The Park Jeffrey R. Johansen1,*, Rex L.

Furey2 Abstract - Great Smoky Mountains National Park, which straddles the Tennessee– North Carolina state-line is a biologically diverse region which has recently become the site of an All Taxon Biodiversity Inventory, an effort to chronicle species diversity by documenting all species in all phyla present within park boundaries. As a result of studies within the last two years, we have added 415 new algal taxa records. With records reported in 2004, we now have documented a total of 1000 taxa in the park. This paper summarizes all algal species found to date. Introduction Great Smoky Mountains National Park (GSMNP) is the largest contiguous preserve east of the Rocky Mountains. Although settled and logged for many years, the Park has retained much of its diverse fl ora and fauna due to the rugged terrain and long period of protection since becoming a national park in 1934. The north–south orientation of the Park, its complex geology, elevational variety, and moist climate contribute to high species biodiversity. Because of the mountainous terrain, old-growth forest patches that have never been cleared for lumber still exist within park, and serve as pristine refugia for some species. In December of 1997, the All Taxon Biodiversity Inventory (ATBI) was undertaken to identify every species in every phylum present in the park (Pederson 1999). As of August 2001, 450 vertebrate, 2250 fungal, 2816 higher plant, and 4280 invertebrate species records had been documented in the Park (Sharkey 2001). Algal records were compiled and published by Johansen et al. (2004). The 585 taxa reported in that publication included historical published records, historical gray literature, and recent collection efforts. The historical literature for the algae in the Park is summarized in that publication. Other publications based on unusual records have since been published or have been accepted for publication (Casamatta et al. 2006, Johansen et al. 2005). 99 The Great Smoky Mountains National Park All Taxa Biodiversity Inventory: A Search for Species in Our Own Backyard 2007 Southeastern Naturalist Special Issue 1:99–134 100 Southeastern Naturalist Special Issue 1 The purpose of this paper is to report all new records and to present the taxa in a more phylogenetic context based on recent systematic studies. Materials and Methods Efforts in recent years have focused on several habitats within the Park. As became clear in Gomez et al. (2003), moist aerial habitats in the Park (particularly seeps, wet rock faces, and waterfall splash zones) are especially rich in interesting species. We made special efforts to sample these habitats, and the habitats studied since the Gomez (2002) study are listed in Appendix A. The other understudied habitats were lentic, and included some small standing bodies of water in Cades Cove, as well as the northern shoreline of Fontana Lake, which contains the Park boundary in its deepest course. We studied both the littoral and pelagic zones of Fontana Lake. Other miscellaneous sites such as waterfalls, sinks and streams from less-accessable areas of GSMNP were sampled as well. Sites were found with the help of maps and guidebooks (Anonymous 1994, 1998). While in the field, all samples were divided into portions for fresh examination and preservation. A rough portion of each was transferred to polycarbonate bottles, preserved in 2% glutaraldehyde, and kept under refrigeration for the duration of the study. Diatom slides were made from all samples for future analysis. All taxa were examined and photographed using Olympus BX51, Olympus B-Max, and Zeiss Axiophot photomicroscopes with high resolution Nomarski DIC optics. Recently collected materials are still being used for continued study, but will eventually be deposited at the California Academy of Sciences (both preserved material and diatom slides). Images and drawings of most taxa exist and will be illustrated in several taxon-specific fl oras to be published at the conclusion of the study. Several diatom taxa, particularly those with structure too fine to discern in light microscopes, were also examined with a high resolution Hitachi HHS-2R scanning electron microscope (SEM) at Bowling Green State University (BGSU). Diatoms were cleaned in boiling nitric acid and air dried onto cover glasses. Each cover glass was mounted on a specimen stub, sputter-coated with 10 nm gold-palladium alloy prior to SEM analysis. Preserved samples that contained dinofl agellates were dehydrated in a graded alcohol series, critical-point dried, sputter-coated with gold-palladium alloy, then studied in the BGSU SEM microscope. Taxonomic determinations were made using standard references. For cyanobacteria, Desikachary (1959), Geitler (1932), Komárek and Anagnostidis (1999, 2005), and Starmach (1966) were the primary references for species, with generic assignments following the recent revisions of Komárek and Anagnostidis (Anagnostidis and Komárek 1985, 1988, 1990; Komárek and Anagnostidis 1986, 1989). References used for identifying green algae were diverse (Croasdale and Flint 1986, 1988; Croasdale et al. 1994; Dillard 1990, 1991a, 1991b, 1993; Ettl and Gärtner 1995; Komárek and Fott 1983; 2007 J.R. Johansen et al. 101 Lokhorst 1996). Diatoms were also identified using a number of texts (Krammer 1997a, 1997b; Krammer and Lange-Bertalot 1986, 1988, 1991a, 1991b; Lange-Bertalot 2001; Lange-Bertalot and Metzeltin 1996; Patrick and Reimer 1966, 1975). For tribophytes and eustigmatophytes, Ettl and Gärtner (1995) was the primary resource. Placement of cyanobacteria in higher-level taxa follows Hoffmann et al. (2005). This new classification is based on sequence-based phylogenies as well as ultrastructural and morphological criteria. It represents a radical departure from classification schemes of the 20th century, but we concur with Hoffmann et al. (2005) that this system is superior. Placement of diatom taxa in higher taxonomic groups follows the system of Round et al. (1990). Placement of coccoid chlorophyte genera in higher-level taxa is problematic. We followed the scheme of Graham and Wilcox (2000), informed by a number of recent phylogenetic studies (Booton et al. 1998a 1998b; Friedl and Zeltner 1994; Hanagata 1998; Huss et al. 1999; Lewis 1997). Coccoid taxa known to belong in the Trebouxiophyceae were placed in the Trebouxiales. Coccoid taxa known to have directly opposite (DO) fl agellar ultrastructure, or belong to that clade based upon DNA sequence data, were placed provisionally in the Sphaeropleales. The Chlorococcales contains the coccoid taxa with the clock-wise orientation of fl agellar roots and those azoosporic taxa sharing sequence similarity with those species. Additionally, we found the ITIS website Catalogue of Life: 2005 Annual Checklist (http://annual. sp2000.org/2005/search.php) to be especially helpful in identifying higherlevel taxonomy and correct author designations. Results and Discussion With the combination of recent and older records, the park now has a total of 1000 algal species records (Appendix B): 190 Cyanobacteria, 108 Chlorophyta (Chlorophyceae, Trebouxiophyceae, Ulvophyceae), 137 Charophyta (Klebsormidiophyceae, Zygnematophyceae), 21 Dinophyta, 19 Euglenophyta, 1 Cryptophyta, and 5 Rhodoplantae (Cyanidiophyta, Rhodophyta). Kingdom Stramenopila (formerly synonymous with Heterokontophyta) included the following numbers of taxa in eight phyla: 3 Chrysophyta, 7 Synurophyta, 1 Prymnesiophyta, 1 Raphidiophyta, 16 Tribophyta, 2 Eustigmatophyta, 488 Bacillariophyta, and 1 Phaeophyta. These totals include 82 taxa (“sp.” or as “cf.” taxa) which could be recognized as distinct, but which could not be identified with confidence to species. All of these uncertain taxa are potentially new to science. In the process of examining the algae, we encountered one taxon that was morphologically similar to Merismopedia trolleri Bachman. However, the color and thylakoid structure were incorrect for that taxon (irridescent purplish pink), and we were able to subsequently identify this distinctive bacterium as Thiopedia rosea Vinogradskij (Appendix B). 102 Southeastern Naturalist Special Issue 1 Since Johansen et al. (2004), we have found representatives of six phyla which were not reported previously. These include Cyanidiophyta, Prymnesiophyta, Raphidophyta, Phaeophyta, and Cryptophyta. With 16 phyla represented, the prokaryotic and eukaryotic algae demonstrate deep branching diversity. At this point, all existing freshwater algal phyla are represented within the park. The habitats with richest algal diversity in the park are the subaerial seeps and waterfall splash zones. We have found most of our taxa in these habitats. This may be due to the fact that the streams in the park are almost all high-gradient, thoroughly scoured, nutrient-poor streams with limited ecological variability. Algae in the streams and rivers are mostly tightly attached to the rocky substrate and are very patchy in distribution as well as difficult to sample (Chamaesiphon spp., Heribaudiella sp., and Achnanthidium are good examples). More collection effort in the streams could potentially yield more taxa. The park is especially depauperate in lentic habitats, and this may be the cause for the absence of some common cosmopolitan genera and species. Fontana Lake is the only lentic habitat of any size. A few marshes, a sinkhole, and a black gum swamp are the only other still-water habitats. We have not yet studied the algae of the soils or aerophytic dry habitats such as tree bark and rocks. The subaerial habitats will likely yield the most new taxa with the least collection effort. Johansen et al. (2004) predicted that Batrachospermum would be found within the park, and indeed it was. We are currently working on the identity of the species of this genus, which was found in two watersheds within the park. Other taxa receiving special attention are a new species of Draparnaldia (Johansen and Lowe, 2007), as well as three putative new species of Leptolyngbya (L. appalachiana, L. badia, L. nonconstricta). Fučiková (in press) found one new species of sacoderm desmid in her studies. Thomas et al. (in press) found 14 new records plus 6 new species of gomphonemoid diatoms. These latter taxa are also the subjects of Johansen et al. (in press B). Rexia erecta (Casamatta et al. 2006) is a new genus and species of cyanobacteria described from the park, and we have also discovered a new genus of centric diatom in the Thalassiosiraceae (Johansen et al., in press A), given the provisional name in this manuscript “Spicaticribra kingstonii.” These findings, as well as other new or rare taxa (Casamatta et al. 2006, Johansen et al. 2005), indicate that the Park is home to a distinctive algal flora that is worthy of preservation efforts. As we build the species record list, we recognize that some taxa in our list have been incorrectly identified by past workers. For example, Gomphonema rhombicum, G. ventricosum, and G. micropus were reported in the 1970s based on the literature available at the time, but now we recognize that the organisms that likely represented those reports are new species or at least species described more recently. We have removed some of these 2007 J.R. Johansen et al. 103 records from the list, but where we are not reasonably confident of incorrect identification, we have left the names on the list. Readers can make their own judgement concerning records by examining the date of the reports (Appendix B). Johansen et al. (2004) made a number of new taxonomic combinations to refl ect more recent generic concepts in diatoms. One of these taxonomic corrections was actually made prior to 2004. Navicula mobiliensis var. minor Patrick was transfered and elevated to Luticola minor (Patr.) Mayama (Mayama and Kawashima 1998), and is an earlier synonym of Luticola naviculoides Johansen in Johansen et al. (2004). The latter name is thus invalid, and we publish the correction here.
