Sustainable use, protection of animal world and forest 180 management in the context of climate change distribution OF Arrhopalitidae species (COLLEMBOLA: Symphypleona) IN THE REPUBLIC OF Moldova Robert S. Vargovitsh1, Galina Busmachiu2 1Schmalhausen Institute of Zoology, National Academy of Sciences of Ukraine, Kyiv, Ukraine. E-mail: [email protected] 2Institute of Zoology, Academy of Sciences of Moldova, Chişinau. E-mail: [email protected] The first three species of Arrhopalitidae such as Arrhopalites caecus (Tullberg, 1871), Pygmarrhoplaites pygmaeus (Wankel, 1860) and P. secundarius (Gisin, 1958) were cited from the Republic of Moldova by Buşmachiu, 2010. The new investigation concerning the fauna of Arrhopalitidae collected from eigh- teen localities from the Republic of Moldova show that the family Arrhoplaitidae are represented by two genera and four species each: Arrhopalites with Arrhopalites sp. gr. diversus, A. caecus, A. prutensis Vargovitsh & Busmachiu, 2015, A. ulehlovae Rusek, 1970 and Pygmarrhopalites with Pygmarrhoplaites ornatus (Stach, 1945), P. pygmaeus, P. secundarius and P. terricola (Gisin, 1958). Arrhopalitidae were collected mainly in humid habitats like floodplain forest, banks of rivers Prut, Dniester and Răut, shore of Lake Ghidighici and in the soil, litter and decaying woods of the deciduous forest near Donici locality and two scientific reserves: Codrii and Plaiul Fagului. A total number of sampled Arrhopalitidae includes 120 speci- mens belonging to eight species with peculiar distribution in the studied habitats. A. prutensis Vargovitsh, Busmachiu, 2015 and A. ulehlovae Rusek, 1970 were re- corded on the bank of Prut River only, while Pygmarrhoplaites ornatus (Stach, 1945), Pygmarrhoplaites pygmaeus (Wankel, 1860) and P. secundarius (Gisin, 1958) on the bank of Dniester River only. Several species as Arrhopalites caecus (Tullberg, 1871), Arrhopalites sp. gr. diversus, Pygmarrhoplaites pygmaeus (Wankel, 1860) and P. terricola (Gisin, 1958) were revealed in the soil and decaying stump of the scientific reserves Codrii and Plaiul Fagului. Two species Arrhopalites caecus (Tullberg, 1871) and P. terricola (Gisin, 1958) were common in the most part of studied habitats. The results encouraged us to expand the research over other cities and we expect to raise the list of Moldovian Arrhopalitidae. New collected material includes 15 speci- mens from 5 localities, three of them: Unguri (natural deciduous forest), Varnița (bank of Dniester River) and Condrița (decaying stump from the natural deciduous forest) were not studied before. .

Unexpected Diversity in Neelipleona Revealed by Molecular Phylogeny Approach (Hexapoda, Collembola)
S O I L O R G A N I S M S Volume 83 (3) 2011 pp. 383–398 ISSN: 1864-6417 Unexpected diversity in Neelipleona revealed by molecular phylogeny approach (Hexapoda, Collembola) Clément Schneider1, 3, Corinne Cruaud2 and Cyrille A. D’Haese1 1 UMR7205 CNRS, Département Systématique et Évolution, Muséum National d’Histoire Naturelle, CP50 Entomology, 45 rue Buffon, 75231 Paris cedex 05, France 2 Genoscope, Centre National de Sequençage, 2 rue G. Crémieux, CP5706, 91057 Evry cedex, France 3 Corresponding author: Clément Schneider (email: [email protected]) Abstract Neelipleona are the smallest of the four Collembola orders in term of species number with 35 species described worldwide (out of around 8000 known Collembola). Despite this apparent poor diversity, Neelipleona have a worldwide repartition. The fact that the most commonly observed species, Neelus murinus Folsom, 1896 and Megalothorax minimus Willem, 1900, display cosmopolitan repartition is striking. A cladistic analysis based on 16S rDNA, COX1 and 28S rDNA D1 and D2 regions, for a broad collembolan sampling was performed. This analysis included 24 representatives of the Neelipleona genera Neelus Folsom, 1896 and Megalothorax Willem, 1900 from various regions. The interpretation of the phylogenetic pattern and number of transformations (branch length) indicates that Neelipleona are more diverse than previously thought, with probably many species yet to be discovered. These results buttress the rank of Neelipleona as a whole order instead of a Symphypleona family. Keywords: Collembola, Neelidae, Megalothorax, Neelus, COX1, 16S, 28S 1. Introduction 1.1. Brief history of Neelipleona classification The Neelidae family was established by Folsom (1896), who described Neelus murinus from Cambridge (USA).

Apresentação O presente trabalho traz informações a respeito dos animais invertebrados, com destaque para aqueles que habitam o ambiente cavernícola. Sem qualquer pretensão de esgotar um assunto tão vasto, um dos objetivos principais deste guia básico de identificação é apresentar e caracterizar esse grande grupo taxonômico de maneira didática e objetiva. Este guia de identificação foi elaborado para auxiliar os técnicos e profissionais de várias áreas de conhecimento nos trabalhos de campo e nas vistorias técnicas realizadas pelo Ibama. É preciso esclarecer que este guia não pretende formar “especialista”, mesmo porque para tanto seriam necessários muitos anos de dedicação e aprendizado contínuo. Longe desse intuito, pretende- se apenas que este trabalho sirva para despertar o interesse quanto à conservação dos invertebrados de cavernas (meio hipógeo) e também daqueles que vivem no ambiente externo (meio epígeo).

E-mail: [email protected] 3Corresponding author Abstract Three new species of cavernicolous Collembola belonging to genera Pygmarrhopalites and Oncopodura from five caves at El Maestrazgo (Teruel, Spain) are described: Pygmarrhopalites maestrazgoensis sp. nov., P. cantavetulae sp. nov. and Oncopodura fadriquei Jordana & Baquero sp. nov. In addition five other species have been found in the same caves: Heteromurus nitidus (Templeton, 1836), Pseudosinella encrusae Gisin & Gama, 1969 (second record of the species), Megalothorax minimus Willem, 1900, Protaphorura aconae Arbea & Jordana 1994 (second record of the species), and Schaefferia decemoculata (Stach, 1939) (sensu: Thibaud 1970). The explorations of cave fauna in these cavities has been carried out by the "Associació Catalana de Bioespeleologia” under the sponsorship of CEMAT (Centro de Estudios del Maestrazgo Turolense). Key words: Collembola, Arrhopalitidae, Pygmarrhopalites, Oncopoduridae, Oncopodura, biospeleology, taxonomy Introduction The “Associació Catalana de Bioespeleologia” conducted a first bio-speleological sampling sufficiently comprehensive for a group of caves Maestrazgo Region (Teruel, “Iberic Range”). This range has been poorly studied for Iberian wildlife because of its traditional geographic isolation, and an average altitude of 1500 meters with summits of 2000 m (Lozano 2007).

TREWICK defining feature of the Hexapoda, as the name suggests, is six legs. Also, the body comprises a head, thorax, and abdomen. The number A of abdominal segments varies, however; there are only six in the Collembola (springtails), 9–12 in the Protura, and 10 in the Diplura, whereas in all other hexapods there are strictly 11. Insects are now regarded as comprising only those hexapods with 11 abdominal segments. Whereas crustaceans are the dominant group of arthropods in the sea, hexapods prevail on land, in numbers and biomass. Altogether, the Hexapoda constitutes the most diverse group of animals – the estimated number of described species worldwide is just over 900,000, with the beetles (order Coleoptera) comprising more than a third of these. Today, the Hexapoda is considered to contain four classes – the Insecta, and the Protura, Collembola, and Diplura. The latter three classes were formerly allied with the insect orders Archaeognatha (jumping bristletails) and Thysanura (silverfish) as the insect subclass Apterygota (‘wingless’). The Apterygota is now regarded as an artificial assemblage (Bitsch & Bitsch 2000).

Milne4, Nicholas S. Gladstone5, Annette S. Engel6, John B. Jensen7, Carlos D. Camp8, James C. Ozier9, and Alan Cressler10 Abstract We provide an annotated checklist of species recorded from caves and other subterranean habitats in the state of Georgia, USA. We report 281 species (228 invertebrates and 53 vertebrates), including 51 troglobionts (cave-obligate species), from more than 150 sites (caves, springs, and wells). Endemism is high; of the troglobionts, 17 (33 % of those known from the state) are endemic to Georgia and seven (14 %) are known from a single cave. We identified three biogeographic clusters of troglobionts. Two clusters are located in the northwestern part of the state, west of Lookout Mountain in Lookout Valley and east of Lookout Mountain in the Valley and Ridge. In addition, there is a group of tro- globionts found only in the southwestern corner of the state and associated with the Upper Floridan Aquifer. At least two dozen potentially undescribed species have been collected from caves; clarifying the taxonomic status of these organisms would improve our understanding of cave biodiversity in the state.

Box 7, Mammoth Cave, KY 42259, USA; [email protected] * Correspondence: [email protected] or [email protected] Abstract: The Mammoth Cave System in the Interior Low Plateau karst region in central Kentucky, USA is a global hotspot of cave-limited biodiversity, particularly terrestrial species. We searched the literature, museum accessions, and database records to compile an updated list of troglobiotic and stygobiotic species for the Mammoth Cave System and compare our list with previously published checklists. Our list of cave-limited fauna totals 49 species, with 32 troglobionts and 17 stygobionts. Seven species are endemic to the Mammoth Cave System and other small caves in Mammoth Cave National Park. The Mammoth Cave System is the type locality for 33 cave-limited species. The exceptional diversity at Mammoth Cave is likely related to several factors, such as the high dispersal potential of cave fauna associated with expansive karst exposures, high surface productivity, and a long history of exploration and study. Nearly 80% of the cave-limited fauna is of conservation concern, many of which are at an elevated risk of extinction because of small ranges, few occurrences, Citation: Niemiller, M.L.; Helf, K.; and several potential threats.

Cave Dwelling Springtails (Collembola) of Hungary: a Review
S O I L O R G A N I S M S Volume 83 (3) 2011 pp. 419–432 ISSN: 1864-6417 Cave dwelling springtails (Collembola) of Hungary: a review László Dányi Systematic Zoology Research Group of the Hungarian Academy of Sciences, and Department of Zoology, Hungarian Natural History Museum, Baross u. 13. H-1088, Budapest, Hungary e-mail: [email protected] Abstract A historical review of Hungarian cave springtail studies is given. All literature concerning this field is compiled and the species are listed along with their localities. In spite of the relatively low number of caves investigated regarding their Collembola fauna, 67 species have been reported from Hungarian caves until now. Eleven taxa are endemic to the cave or karst system where they were described from, which indicates highly promising perspectives for further biospeleological research in Hungary. The listed species are discussed in relation to the collembolan fauna of neighbouring countries and an attempt is made to discern zoogeographical patterns within the country. Keywords: Biospeleology, troglobiont, faunistics, endemism, subterranean 1. Introduction Cave fauna is generally highly specific and especially interesting for faunistics, biogeography and evolutionary biology (Romero 2009). Thus, Hungarian biospeleological research started as early as the middle of the 18th century (Frivaldszky 1865). In spite of this, caves in this country are far from being thoroughly investigated regarding their Collembola fauna, even though Hungary is relatively poor in caves due to its geographical situation compared with surrounding countries. Nevertheless, work in this field almost completely ceased in Hungary towards the end of the 1960’s, while biospeleological studies on springtails continued in neighbouring countries (see for example Kováč 2000, Novak 2005 and Kováč & Papáč 2010 for Slovakia, Gruia 2003 for Romania, Vargovich 2005 for the Ukraine, Lukić & Deharveng 2008 and Lukić et al.

E-mail: [email protected] ABSTRACT: We investigated fauna and community composition of springtails in the burnt and unburnt boreal forests of European Russia. We also analyzed ecoregional differences in the effect of fire disturbance on collembolan community faunistic similarity on an example of three different ecoregions of the boreal forest biome in the study territory. We collected and identified 6799 springtail individuals representing 14 families, 41 genera and 94 species. In the burnt plots we observed consistent shifts in the springtail community dominance structure across all studied ecoregions. The effect of fire on the faunistic similarity of springtail communities was strongly modulated by ecoregion: within-ecore- gion similarity between plots was always higher than the between-region similarity. Fires resulted in the moderate decrease of the total abundance of springtails with trans-holarctic distribution in all ecoregions and additionally in increase of springtails with west-palaearc- tic distribution in southern ecoregion. We conclude that five years after burning it is very important to standardize fire-induced changes in the faunistic composition of springtail communities to the actual geographic location within spatially extensive biomes.
