Abstract

This paper relates to material obtained during two field trips to the Peloponnese in 2013 and 2016. With the inclusion of some hitherto unpublished ant material, it gives new records from a total of 92 sampling localities. 129 species (including morphospecies not attributed to any known taxon) of ants have been recorded from the Peloponnese (southern Greece), 27 of which have been recorded from this region for the first time. Lasius reginae and 5 other morphospecies attributed only to species complexes are new to Greece.

Abstract

As a result of recent collecting efforts and older unpublished data of one of us (AA), 32 ant species (including 2 morphospecies) new to the island of Sicily (Italy) were discovered. Seven of these taxa represent unequivocally exotic entities, whose discovery marks a decisive increase of this component in the local fauna. Among these, two forms of Nylanderia EMERY, 1906 are treated as morphospecies because of the problematic taxonomy of the genus. Six taxa among the discovered species are entirely new to the myrmecofauna of Italy. Finally, Tetramorium indocile SANTSCHI, 1927 is reported for the first time as a host for the social parasite Strongylognathus testaceus (SCHENCK, 1852). The state of the art of the Sicilian myrmecofauna, now counting about 150 species, is commented on.

Abstract

A complete list of 107 ant species (including morphospecies not attributed to any known taxon) recorded from Thessaly, Greece, is presented. New records from 40 sampling localities explored during two field trips in 2012 and 2017, and also from literature data are included. Temnothorax sordidulus (Müller, 1923) and Temnothorax tauricus (Ruzsky, 1902) are new to Greece; 38 species were recorded from Thessaly for the first time.

Abstract

The occurrence and bioactivities of marine-derived fungi are evaluated in this paper. A total of 16 morphospecies of marine-derived fungi (MDF) were isolated from four host macroalgae and two seagrasses and identified as belonging to the genera Aspergillus, Fusarium, Paecilomyces, Penicillium, Sclerotinia, Thamnidium and Trichoderma, including five mycelia sterilia. Among these host organisms, the rhodophyte Laurencia intermedia harboured the highest number of isolated MDF. Selected MDF were then assayed and showed to inhibit Pseudomonas aeruginosa (8-19 mm zone of inhibition) and Staphylococcus aureus (6-19 mm zone of inhibition), and were cytotoxic against the brine shrimp Artemia salina nauplii (LD50: 201.56-948.37 μg mL−1). The screening led to the selection of five of the most bioactive morphospecies, all belonging to the genus Aspergillus. These marine aspergilli were subjected to β-tubulin gene sequence analysis for species identification, and to mass production in different culture media with or without marine salts, and screening of the crude culture extracts for their cytotoxic and trypanocidal activities. Aspergillus tubingensis cultivated in potato dextrose broth with marine salt proved to be the most cytotoxic against P388 (IC50: 1028 ng mL−1) and HeLa (IC50: 1301 ng mL−1) cancer cells. On the other hand, A. fumigatus cultivated in malt extract broth without marine salt was shown to be the most potent against Trypanosoma congolense (IC50: 298.18 ng mL−1). Our study therefore showed that salinity may influence the bioactivities of some species of MDF.

Abstract

A new nematode species, Subulura mackoi n. sp., is described based on specimens from the colon and caecum of the Eurasian Scops Owl Otus scops (L.) (Aves: Strigiformes) from the Czech Republic, collected in 2011. Males are characterized by 10 pairs of caudal papillae, a single papilla on the upper lip of the cloaca, and small unequal spiculae; female distinguishing features are body length, distance of the vulva from the anterior extremity, tail length, and egg dimension.

Analysis of the zoogeographical distribution and host specialization (in the bird orders) of 68 valid species from the genus Subulura Molin, 1860 shows significantly high species diversity in the tropical zones. Only one species, S. brumpti, is a cosmopolitan parasite of Gallus gallus f. domestica and other domesticated gallinaceous birds. Zoogeographical-host interactions may be utilized to support the identification of morphospecies of the genus Subulura.

Summary

The mite fauna in foliage and litter of a sprayed alfalfa hay field with the acaricide-insecticide bifenthrin, was studied based on monthly samplings from foliage and litter in Central Greece between 2008–2009. Potential differentiations between this field and two adjacent alfalfa hay fields, which were not subjected to pesticide applications and were managed with different number of cuttings, were also evaluated in terms of population fluctuation over time, population density, species richness, diversity and spatial distribution. The sprayed field hosted 50 and 68 species and morphospecies in foliage and litter respectively, depicting high relative abundance of oribatid and prostigmatic mites. Neoseiulus aristotelisi Papadoulis, Emmanouel and Kapaxidi, was a new record for alfalfa, previously found in rice in Macedonia, Greece. The seasonal fluctuation of mites, particularly in foliage, was similar in all fields. The spatial distribution of a Zygoribatula species, which was common and dominant in all fields, was also aggregated. Finally, the sprayed field shared similar mite diversity with the two non-sprayed fields, but not similar species richness.
