We recorded 54 species in overall (fam. Noteridae 1 species, fam. Dytisci- dae 23 species, fam. Carabidae 30 species) (Table 1). Highest number of hydrophilic carabid species was recorded in Dubica (Una 1) and Dvor (Una 5) sites (Figure 4). Majority of the rare Hydradephagan species were recorded in Una 3 site in temporary flooded meadows (Figure 5). The richest Hydradephagan community was found in densely vegetat- ed stagnant water at the river shoreline.

Studii i comunicri. tiinele Naturii, Tom XXIII/2007 ISSN 1454-6914 THE SYNECOLOGICAL ANALYSES OF THE EDAPHIC BEETLES (COLEOPTERA) FROM THE MIXED FOREST (ELM, ASH AND FIELD MAPLE) FROM THE „CODRII TIGHECIULUI” LANDSCAPE RESERVE SVETLANA BACAL Abstract. This paper represents a faunistic and ecological study on the edaphic coleoptera from a mixed forest of the “Codrii Tigheciului” landscape reserve, accomplished during the vegetation period of 2004-2006. The coleopteran fauna from a forest of elm-tree (Ulmus caprinifolia) mixed with ash-tree (Fraxinus excelsior), sycamore (Acer campestre) and maple (Acer platanoides) was represented by 77 species from 37 genera and 7 families. The most well represented was the family Carabidae with 39 species from 16 genera, followed by family Staphylinidae with 15 species from 10 genera, then by the families Silphidae and Scarabaeidae with 9 species each from 4 and respectively 2 genera and the families Lucanidae and Tenebrionidae with 2 species from 2 genera each. The family Trogidae was represented by one species. Within the study the analysis of some analytical ecological indexes was realized, such as the abundance, the dominance, the stability and some synthetic indexes such as the index of ecological significance and the diversity index (the index of real diversity – H(S), the maximum diversity – H(S)max and the relative diversity (evenness).

This survey was to mirror the locations and methodology of a previous survey undertaken during autumn 2016 and spring 2017. Colin Plant Associates also undertook the aquatic invertebrate sampling of this previous survey. 1.1.2 The 2016-17 aquatic survey was commissioned with the primary objective of establishing a baseline aquatic invertebrate species inventory and to determine the quality of the aquatic habitats present across both the Nature Reserve and Southern Marsh areas of the Crossness Sewage Treatment Works. The surveyors were asked to sample at twenty-four, pre-selected sample station locations, twelve in each area. Aquatic Coleoptera and Heteroptera (beetles and true bugs) were selected as target groups. A report of the previous survey was submitted in Sept 2017 (Plant 2017). 1.1.3 During December 2017 a large-scale pollution event took place and untreated sewage escaped into a section of the Crossness Nature Reserve. The primary point of egress was Nature Reserve Sample Station 1 (NR1) though because of the connectivity of much of the waterbody network on the marsh other areas were affected.

E-mail:[email protected] Introduction The most important information on Lithuanian Coleoptera was summarized and published in the monograph „Lietuvos fauna. Vabalai“ (Pileckis & Monsevičius, 1995, 1997). This monograph presents the list of more then 2850 Coleoptera species. However, the latest records (Barševskis, 2001; Ferenca, 2003, 2004; Ferenca et al., 2002, 2006, 2007; Inokaitis, 2004; Monsevičius & Pankevičius, 2001; Šablevičius, 2003, 2004; Šablevičius & Ferenca, 1995; Tamutis, 1996, 2001a, 2001b, 2003, 2004; Tamutis & Ferenca, 2006) contain information on more than 450 species of Lithuanian Coleoptera. This paper presents information on 24 new Coleoptera species for Lithuania. Two species (Chlaenius spoliatus and Harpalus melancholicus) should be removed from the list of Lithuanian Coleoptera, as misidentified. Material and Methods The present data based on the material collected by the authors of this report during field research. Some of the material was deposited in the collection of Kaunas T.

ZooKeys 100: 223–254. doi: 10.3897/zookeys.100.1530 Abstract The results of pitfall trapping are often interpreted as abundance in a particular habitat. At the same time, there are numerous cases of almost unrealistically high catches of ground beetles in seemingly unsuitable sites. The correlation of catches by pitfall trapping with the true distribution and abundance of Carabidae needs corroboration. During a full year survey in 2006/07 in the Lake Elton region (Volgograd Area, Rus- sia), 175 species of ground beetles were trapped. Considering the differences in demographic structure of the local populations, and not their abundances, three groups of species were recognized: residents, migrants and sporadic. In residents, the demographic structure of local populations is complete, and their habitats can be considered “residential”. In migrants and sporadic species, the demographic structure of the local populations is incomplete, and their habitats can be considered “transit”.

(With one map in the text) Abstract. Presented paper is a proposal of a classification of the carabid beetles occurring in Poland to the following zoogeographical elements: Holarctic, Palaearctic, Euroarctic, Euro-Siberian, Euro-Central Asiatic, Euro-Mediterranean and element of the European Forest Province. Biogeography as a science dealing with the problem of distribution of organism communities has developed over last three decades. It is an integration of both animal and plant geography into a unified special branch. This junction seems to be especially reasonable since, so far, any consideration about particu­ lar distribution of animals resulted with an observation of their dependence on the specific vegetation. Recently biogeography has been developing in mamy countries, particularly in the Soviet Union and the USA with both theoretical and utilitarian aspects. The following ends were put to be fulfilled by this knowledge (Teoret. i prikl. aspekty biogeografii, 1982): — explanation of performance and energy balances of ecosystems, — bioindication of elements of landscape (among others for the classifica­ tion purposes), — forecasting of trends in community transformations influenced by na­ tural and anthropogenic factors. According to O b m iń s k i (1974) zoocenosis is a formation which does not exist independently. It is only a “formal unit” built up by researchers, being in fact an integrated part of biocenosis. This opinion had been supported, indepen­ dently fromO b m iń s k i, by S t u g r e n (1975), who established much closer c o n - http://rcin.org.pl 298 A.

[email protected] www.luigidemarzo.eu SUBJECTS • Several terms are applied to the conjugate sperm in the Animal kingdom (Pitnick et al., 2009); • referring to Insects, they include: • (I) “spermatozeugma” (etymology: from the Greek, sperma = seed and zeugma = join), which is defined by Maggenti (2005) as “united by fusion of two or more spermatozoa”; • (II) “spermatostyle”, which indicates the elongate supporting structure occurring in several beetles of the families Carabidae and Gyrinidae (Breland & Simmons, 1970; Crowson, 1981; Paulian, 1981). • Interspecific variability of the spermatostyles in Carabidae has been preliminary analyzed elsewhere (De Marzo, 1995). • Some unpublished micrographs on the same subject are presented here. MATERIAL AND METHODS • Examined species are reported in the following chapter. • Spermatozeugmata were obtained by squashing testes of males killed with ethyl acetate vapours in salt solution (NaCl 0,9%). • Micrographs at the light-microscope were taken with 40x phase- contrast lens on samples in the above solution. • Images at the confocal laserscanning microscope were taken on samples mounted on slide in glycerol. RESULTS • Spermatozeugmata lacking in spermatostyle were observed in subfamilies/species as follows: - Bembidiinae, Asaphidion rossii (Schaum), Ocydromus ascendens (Daniel); - Brachininae, Brachinus psophia Serville; - Carabinae, Calosoma sycophanta (Linnaeus), Carabus violaceus germarii Sturm; 2 - Callistinae, Chlaenius chrysocephalus (Rossi). • Presence of spermatostyle has been recorded in the taxa listed in the following table, which reports values of length as well.

MgA. David Boukal, Ph.D. České Bud ějovice 2008 1 Bachelor Thesis Kle čka, J., 2008: The structure and dynamics of a water beetle community in a semipermanent wetland (Vrbenské rybníky Nature Reserve, South Bohemia). BSc. Thesis, in English – 63 pp., Faculty of Science, The University of South Bohemia, České Bud ějovice, Czech Republic. Annotation In my thesis I examined the structure and dynamics of a water beetle community in a semipermanent wetland in an alder carr. The results are based on three years of my field work and processing of material collected by a light trap at the study site during five years. The thesis focuses on: 1. Comparison of selectivity and efficiency of several widely used sampling methods; 2. Seasonal dynamics and effects of environmental variables on flight acitivity; 3. Spatiotemporal dynamics and effects of habitat structure and fluctuations in water levels. General patterns and relationships are highlighted.
