Read Full License Page 1/25 Abstract Exploitation of organisms by multiple parasite species is common in nature, but interactions among parasites have rarely been studied. Myrmica ants are rich in parasites. Among others, the ectoparasitic Rickia wasmannii fungus and the socially parasitic caterpillars of myrmecophilous Phengaris butteries often infect the same Myrmica colonies. In this study, we examined the effects of R. wasmannii on the adoption, long-term development, and survival of P. alcon. In laboratory conditions, caterpillars introduced into nests of Myrmica scabrinodis uninfected with R. wasmannii survived signicantly longer compared to caterpillars introduced into infected nests. In the eld, joint infection was less common than expected if both parasites exploited M. scabrinodis colonies independently. Pre-pupal caterpillars of P. alcon were somewhat larger in nests infected with R. wasmannii than those found in uninfected nests. Based on these results it seems that R. wasmannii infection of M. scabrinodis affects the survival and development of P.

  • Biodiversity of the Water Reservoirs in the Vicinity of Usje Marl Quarry
    Biodiversity of the Water Reservoirs in the Vicinity of Usje Marl Quarry S.Petkovski, (1); I.Mastoris, (2); N.B.Kormusoska, (3); (1) NGO BIOECO Skopje, Republic of Macedonia (2) TITAN Cement Company S.A., Athens, Greece (3) Cementarnica “Usje” A.D., Skopje, Republic of Macedonia [email protected] Abstract In line with the activities of WBCSD/CSI task force on biodiversity, Titan uses specific tools for screening Group quarries versus areas of high biodiversity value, like the EMERALD network of Macedonia. The water reservoirs (artificial lakes) inside the Usje Marl Quarry, in proximity with the Titan Cement Plant Usje (Skopje, Macedonia), were gradually ‘formed’ in the 1980’s, after excavating closed pits inside the mine plan area. Freshwater supply to these confined water bodies is due to precipitation and surface rainwater inflows. Plant and animal species have inhabited the area, including the lakes, by natural processes, except the fish stocking that was made by the sport fishermen employed with Usje. Currently, the area more or less resembles a natural wetland ecosystems. By initiative of Usje, and in line with Titan’s Corporate Social Responsibility Policy, an Investigation Study on Hydrology, Hydrogeology & Biodiversity was conducted. This paper is going to present findings and recommendations of the investigation related to biodiversity. Besides the check lists of recorded species, for certain taxonomic groups a “potential list of species” was prepared, as a tool for evaluation of the quality of habitats. Despite the inevitable environmental degradation, the degree to which the terrestrial and aquatic ecosystems and associated species have survived, even in a modified and reduced state, is surprising.

Maculinea nausithous (Bergsträsser, 1779) was recently discovered in two parts of the Tran- sylvanian basin. External characters of these populations completely agree with the original description of Maculinea nausithous kijevensis (Sheljuzhko, 1928) and show some small but constant differences against the Central European nominotypic populations. Since the habitats and host ant selection of these popula- tions are also different from the Central European populations, we consider M. nausithous kijevensis stat. rev. as valid subspeciÀ c taxon. Specimens with the same external characters were also collected in north- eastern Romania, in Kazakhstan and in the western part of the Altai Mts. Therefore we believe that this subspecies has a wider Euro-Siberian distribution. Introduction The Dusky Large Blue, Maculinea nausithous (Bergsträsser, 1779) 1, has a Euro- Siberian distribution with a wide but sporadic range from Western and Central Europe to Kazakhstan, Southern Siberia and Mongolia (Lukhtanov & Lukhtanov 1994; Tuzov 1997; Wynhoff 1998; Munguira & Martín 1999).

  • Intensive Mowing Effect of One Patch on the Metapopulations of Two Phengaris Species*
    ENVIRONMENTAL SCIENCES INTENSIVE MOWING EFFECT OF ONE PATCH ON THE METAPOPULATIONS OF TWO PHENGARIS SPECIES* T. Bubová, M. Kulma, D. Koleška, V. Vrabec Czech University of Life Sciences Prague, Faculty of Agrobiology, Food and Natural Resources, Prague, Czech Republic In the second half of the 20th century, change of land use in the name of intensive agriculture was one of the most important factors caused significant loss of butterfly diversity in Europe. Phengaris nausithous and Phengaris teleius belong among the flagship species associated with wet meadows and are directly threatened by the intensive agriculture practises or management abandonment. Due to their very specific lifecycle, they are closely linked to their habitats and appropriate mowing manage- ment on their patches is thus crucial for their survival. Our research took place in Dolní Labe, Děčín, Czech Republic, on 16 patches and has been performed using Mark-Release-Recapture since 2009. This paper will illustrate how intensive mow- ing management, applied on only one of the patches, which forms only 9.4% of total locality size, can influence the entire local Phengaris metapopulation. The selected patch was intentionally mowed in the middle of flight season annually for four years. Even though, no significant effect was identified after the first year of study, after the second and third seasons, there was evidence of population decline of both studied species.

It was identified with Arge nigrovaginata Malaise, 1931, described from the Russian Far East, for more than seven decades, but a recent examination of Malaise’s type material has revealed the misidentification. Previously unknown immature stages are described, new host plant records are given, and the distribution and life history are discussed based on the specimens examined and rearing experiments. The mostly greenish, solitary and cryptic larvae feed on the leaves of Potentilla and Sanguisorba (also Fra- garia and Duchesnea in the laboratory), all belonging to the clade Sanpotina of the Rosaceae. Arge indicura probably has three generations a year in the lowland of central Honshu. Key words : Argidae, Arge indicura, new species, Potentilla, Sanguisorba.

Several populations went extinct, no less dance. than 9 did so in the 1990s including extinctions in nature reserves. Our analyses indicate that populations of smal- . ler, more isolated sites have a significantly higher extinc­ tion probability. At present, only 12 populations remain in 8 areas, including 5 nature reserves and 3 military areas (table I). Based on detailed egg counts, most populations show negative trends. We have recently finalised a Spe­ cies Action Plan for Maculinea a/con funded by the Flemish Ministry of Nature Conservation (VAN REUSEL et al. 2000). It was the first action plan for an invertebrate, but Flanders has only little experience with the imple­ mentation of such plans and with the integration of spe­ before 1991 cies-specific knowledge into site-oriented conservation. Hence, the M. a/con plan will be an important test-case.

However it has been abandoned as an area of lepidopterological studies for a long time. A total number of 80 butterfly species were recorded during inventory studies (2005-2008), which proved the occurrence of 80 species (81.6% of species recorded in the Mazovia voivodeship and about half of Polish fauna), including 7 from the European Red Data Book and 15 from the national red list (8 protected by law). Several xerothermophilous species have probably become extinct in the last few decadesColias ( myrmidone, Pseudophilotes vicrama, Melitaea aurelia, Hipparchia statilinus, H. alcyone), or are endangered in the KNP and in the region (e.g. Maculinea arion, Melitaea didyma), due to afforestation and spontaneous succession. Higrophilous butterflies have generally suffered less from recent changes in land use, but action to stop the deterioration of their habitats is urgently needed.
