Microhyla Berdmorei
21 THE STOMACH CONTENTS OF SOME ANURAN TADPOLES FROM THAILAND Benjawan Moonasa1, Prapaiporn Thongproh1, Ekachai Phetcharat2, Wassana Kingwongsa3, Pramote Ratree4, Prateep Duengkae5, Theerasak Somdee6, Yodchaiy Chuaynkern1 & Chantip Chuaynkern1,* ABSTRACT The stomach contents of 18 tadpole species in Thailand were studied. The tadpoles in this study consisted of one species of the family Bufonidae (Duttaphrynus melanostictus); one species of Dicroglossidae (Fejervarya limnocharis); four species of Megophryidae (Megophrys carinense, Megophrys sp., Leptobrachium smithi and Leptolalax sp.); six species of Microhylidae (Microhyla butleri, Microhyla berdmorei, Microhyla heymonsi, Micryletta inornata, Kaloula pulchra and Glyphoglossus molossus); three species of Ranidae (Clinotarsus penelope, Hylarana erythraea and Sylvirana nigrovittata); and three species of Rhacophoridae (Polypedates leucomystax, Rhacophorus rhodopus and Rhacophorus jarujini). Tadpole specimens were collected by net from the following five areas: Phu Khiao Wildlife Sanctuary in Chaiyaphum Province, Yoddom Wildlife Sanctuary in Ubon Ratchathani Province, Phu Kradueng National Park in Loei Province, Umphang Wildlife Sanctuary in Tak Province, and Nam Nao National Park in Phetchabun Province. Specimens were dissected in order to remove their stomachs. All stomach contents were kept in order to create semi-permanent slides, which were observed under the light microscope. The results of tadpole stomach contents showed eight groups of food items, which included microalgae (25 genera), protozoa (3 genera), fungi like-organisms, rotifers (3 genera, including amictic eggs and bdelloid rotifers), diatoms (16 genera), arthropods, nematodes, and plant parts. Keywords: Amphibian, diet, food items, stomach analysis, Thailand INTRODUCTION Food is an important welfare factor for all living organisms. In amphibians, caecilians generally feed on earthworms and other invertebrates, while anurans and salamanders feed almost exclusively on insects (Vitt & Caldwell, 2009). -
Microalgae of Protected Lakes of Northwestern Ukraine
Polish Botanical Journal 62(1): 61–76, 2017 e-ISSN 2084-4352 DOI: 10.1515/pbj-2017-0008 ISSN 1641-8190 MICROALGAE OF PROTECTED LAKES OF NORTHWESTERN UKRAINE Yuriy Malakhov 1, Olha Kryvosheia & Petro Tsarenko Abstract. The paper reports the first comprehensive study of microalgal species composition in four lakes of Volhynian Polissya (northwestern Ukraine), in which 271 species (279 intraspecific taxa) of 11 microalgal phyla were identified. Four dominant phytoplankton assemblages were determined for each lake. Bacillariophyta and Charophyta formed more than half (59.2%) of the taxonomic list, accounting for 94 and 66 species respectively. Desmidiaceae was the most diverse family, with 44 species (47 intraspecific taxa) of microalgae. The four lakes are highly dissimilar in species richness and composition, having only 8 (2.9%) species in common. Lake Cheremske had the highest number of algal species – 137 (144). Lake Bile, Lake Somyne and Lake Redychi were much less diverse, with 105, 79 (80) and 75 (78) species respectively. Morphological descriptions, original microg- raphies and figures are presented for a number of species, including some not previously documented in Ukraine: Chromulina cf. verrucosa G. A. Klebs, Eunotia myrmica Lange-Bert. and E. tetraodon Ehrenb. The lakes, which are almost pristine or are recovering, maintain diverse and valuable algal floras, making them important sites in the Pan-European ecological network.

Botswana), a Subtropical Flood-Pulsed Wetland
Biodiversity and Biomass of Algae in the Okavango Delta (Botswana), a Subtropical Flood-Pulsed Wetland Thesis submitted for the degree of Doctor of Philosophy by LUCA MARAZZI University College London Department of Geography University College London December 2014 I, LUCA MARAZZI, confirm that the work presented in this thesis is my own. Where information has been derived from other sources, I confirm that this has been indicated in the thesis. LUCA MARAZZI 2 ABSTRACT In freshwater bodies algae provide key ecosystem services such as food and water purification. This is the first systematic assessment of biodiversity, biomass and distribution patterns of these aquatic primary producers in the Okavango Delta (Botswana), a subtropical flood-pulsed wetland in semiarid Southern Africa. This study delivers the first estimate of algal species and genera richness at the Delta scale; 496 species and 173 genera were observed in 132 samples. A new variety of desmid (Chlorophyta) was discovered, Cosmarium pseudosulcatum var. okavangicum, and species richness estimators suggest that a further few hundred unidentified species likely live in this wetland. Rare species represent 81% of species richness and 30% of total algal biovolume. Species composition is most similar within habitat types, thus varying more significantly at the Delta scale. In seasonally inundated floodplains, algal species / genera richness and diversity are significantly higher than in permanently flooded open water habitats. The annual flood pulse has historically allowed more diverse algal communities to develop and persist in these shallower and warmer environments with higher mean nutrient levels and more substrata and more heterogenous habitats for benthic taxa. These results support the Intermediate Disturbance Hypothesis, Species-Energy Theory and Habitat Heterogeneity Diversity hypotheses. -
Diversity of Desmids in Three Thai Peat Swamps*
Biologia 63/6: 901—906, 2008 Section Botany DOI: 10.2478/s11756-008-0140-x Diversity of desmids in three Thai peat swamps* Neti Ngearnpat1, Peter F.M. Coesel2 &YuwadeePeerapornpisal1 1Department of Biology, Faculty of Science, Chiang Mai University,Chiang Mai 50200, Thailand; e-mail: [email protected], [email protected] 2Institute for Biodiversity and Ecosystem Dynamics, University of Amsterdam, Kruislaan 318,NL-1098 SM Amsterdam, The Netherlands; e-mail: [email protected] Abstract: Three peat swamps situated in the southern part of Thailand were investigated for their desmid flora in relation to a number of physical and chemical habitat parameters. Altogether, 99 species were encountered belonging to 22 genera. 30 species are new records for the Thai desmid flora. Laempagarung peat swamp showed the highest diversity (45 species), followed by Maikhao peat swamp (32 species) and Jud peat swamp (25 species). Despite its relatively low species richness, Jud swamp appeared to house a number of rare taxa, e.g., Micrasterias subdenticulata var. ornata, M. suboblonga var. tecta and M. tetraptera var. siamensis which can be considered Indo-Malaysian endemics. Differences in composition of the desmid flora between the three peat swamps are discussed in relation to environmental conditions. Key words: desmids; ecology; peat swamps; Indo-Malaysian region; Thailand Introduction The desmid flora of Thailand has been investigated by foreign scientists for over a hundred years. The first records of desmids were published by West & West (1901). After that there were reports by Hirano (1967, 1975, 1992), Yamagishi & Kanetsuna (1987), Coesel (2000) and Kanetsuna (2002). The checklist of algae in Thailand (Wongrat 1995) mentions 296 desmid species plus varieties, belonging to 22 different genera. -
The Genus Spondylosium Brebisson Ex Kützing in Waterbodies of West Siberia (Russia)
BIO Web of Conferences 24, 00061 (2020) https://doi.org/10.1051/bioconf/20202400061 International Conferences “Plant Diversity: Status, Trends, Conservation Concept” 2020 The genus Spondylosium Brebisson ex Kützing in waterbodies of West Siberia (Russia) Yuri V. Naumenko1* 1Central Siberian Botanical Garden of the Siberian Branch of the Russian Academy of Sciences, 101 Zolotodolinskaya Str., Novosibirsk, 630090, Russia Abstract. The article generalizes data on the species diversity of the genus Spondylosium Brebisson ex Kützing representatives in waterbodies of West Siberia, their distribution over zones and subzones. At present, 8 species and intraspecific taxa of the order Desmidiales are known in the region. These family representatives are mosaic spread throughout the territory of West Siberia. The largest numbers of taxa (5) are found in middle taiga, 1 and 3 taxa – in southern and northern taiga, respectively, from 2 to 4 taxa - in other zones. No species is recorded in the steppe zone. 6 species (7 taxa) of this genus are identified in lakes of diverse types, 4 species are known in streams, 2 species - in mires and temporary waterbodies. The analysis of the species confinement to environmental conditions has shown that the genus representatives can serve as indicators of acidic and slightly mineralized water. Indifferents (6 taxa) predominate as mineralization indicators, acidophiles (6 taxa) prevail among pH indicators. 1 Introduction The genus Spondylosium Brebisson ex Kützing was described by L. A. Brebisson, a French naturalist, in 1844; its systematic position was clarified by F. Kützing in 1849. The genus species are distinguished from other genera of the order Desmidiales (family Desmidiaceae) by their peculiar cell structure. -

Taxonomy and Nomenclature of the Conjugatophyceae (= Zygnematophyceae)
Review Algae 2013, 28(1): 1-29 http://dx.doi.org/10.4490/algae.2013.28.1.001 Open Access Taxonomy and nomenclature of the Conjugatophyceae (= Zygnematophyceae) Michael D. Guiry1,* 1AlgaeBase and Irish Seaweed Research Group, Ryan Institute, National University of Ireland, Galway, Ireland The conjugating algae, an almost exclusively freshwater and extraordinarily diverse group of streptophyte green algae, are referred to a class generally known as the Conjugatophyceae in Central Europe and the Zygnematophyceae elsewhere in the world. Conjugatophyceae is widely considered to be a descriptive name and Zygnematophyceae (‘Zygnemophyce- ae’) a typified name. However, both are typified names and Conjugatophyceae Engler (‘Conjugatae’) is the earlier name. Additionally, Zygnemophyceae Round is currently an invalid name and is validated here as Zygnematophyceae Round ex Guiry. The names of orders, families and genera for conjugating green algae are reviewed. For many years these algae were included in the ‘Conjugatae’, initially used as the equivalent of an order. The earliest use of the name Zygnematales appears to be by the American phycologist Charles Edwin Bessey (1845-1915), and it was he who first formally redistrib- uted all conjugating algae from the ‘Conjugatae’ to the orders Zygnematales and the Desmidiales. The family Closte- riaceae Bessey, currently encompassing Closterium and Spinoclosterium, is illegitimate as it was superfluous when first proposed, and its legitimization is herein proposed by nomenclatural conservation to facilitate use of the name. The ge- nus Debarya Wittrock, 1872 is shown to be illegitimate as it is a later homonym of Debarya Schulzer, 1866 (Ascomycota), and the substitute genus name Transeauina Guiry is proposed together with appropriate combinations for 13 species currently assigned to the genus Debarya Wittrock. -
