In this study, the species composition and diversity of dragonfly and damselfly assemblages of six post-mining ponds differing in habitat conditions, located within a single sand pit in the central part of the Sandomierz Forest (SE Poland) were assessed. In total, 42 species were recorded in 2019, including 35 species considered resident to the site. In the six studied ponds, a range of 8 to 30 species were recorded, including 5 to 26 resident species. In each pond, at least one unique species was found, and one-third of all species were confined to single ponds only. As a result, the qualitative (Jaccard) and quantitative (Bray-Curtis) similarity indices between the pairs of ponds were low, reaching 12-61% and 19-53%, respectively. Thus, despite a lack of distinct barriers and negligible distances between the ponds (max. 350 m), the structure of assemblages in adjacent water bodies differed considerably. This is probably largely due to the habitat selectivity of species. A redundancy analysis (RDA) showed, that factors such as area and plant diversity of the pond were shaping odonate assemblages, explaining 49.1% of the total variance in the dataset. Due to the high species richness and the identification of several species of special concern, the studied sand pit should be considered a valuable secondary habitat for odonates, which – after termination of exploitation – should be regarded as a good candidate for a site designated for the conservation of biodiversity.

For over a hundred years the Irish céilí, as an ‘invented’ social dance event and mode of interaction, has played a significant and changing role. This paper examines the invention of this Irish dance event and how it has developed in Ireland throughout the twentieth century. From the Gaelic League's cultural nationalist, ideological agenda of the late nineteenth century, for a culturally unified Ireland, to the manifestation of a new cultural confidence in Ireland, from the 1970s, this paper explores how the céilí has provided an important site for the construction, experiencing and negotiation of different senses of community and identity.

AbstractKnowledge of the effects of variables that can influence trapping results should help to optimise efforts in exotic species detection and other surveys. Two vertical trap placements (understorey, canopy) were tested to determine influence of these two heights on captures of Scolytinae (Coleoptera: Curculionidae), Cerambycidae (Coleoptera), and Siricidae (Hymenoptera) using semiochemical-baited multiple-funnel traps. Traps were baited with α-pinene, ethanol, ipsdienol, and ipsenol. A total of 8463 insects from 65 species and one genus were captured during the study. Average species richness, species diversity, abundance, number of unique species, and expected diversity were higher in understorey compared with canopy traps. Jaccard (0.94 ± 0.05) and Sørensen abundance (0.97 ± 0.03) similarity indices suggested highly similar communities sampled at the two trap heights. Dendroctonus valens LeConte, Dryocoetes autographus Ratzeburg, Hylastes opacus Erichson, Orthotomicus caelatus (Eichhoff), Gnathotrichus materiarius (Fitch), Asemum striatum (Linnaeus), Monochamus scutellatus scutellatus (Say), Rhagium inquisitor (Linnaeus), and Xylotrechus sagitattus sagitattus (Germar) were more abundant in understorey traps. In contrast, Ips pini (Say), Pityogenes hopkinsi Swaine, Monochamus carolinensis (Olivier), Acmaeops proteus (Kirby), and Astylopsis sexgutatta (Say) were more abundant in canopy traps. The common practice of trapping in the understorey may be optimal for sampling arboreal insects as part of survey efforts. However, additional species may be found by trapping at other vertical placements.

ABSTRACTA 100-ha quadrat of primary rainforest in French Guiana was ccnsused over two consecutive years by the mapping method, and a 24-ha core area was intensively mistnetted at the same time. More extensive surveys were conducted in successively larger areas including up to a large part of the forested interior of the country. From a total of 441 resident species found in the rainforest zone, 248 were regularly recorded within the 100-ha plot, 157 of which had mean densities of more than 1 pair km-2. The total estimated density of birds was at least 829 pairs km-2. Only two dominant species exceeded 20 pairs km-2, while 52% of all the species were represented by less than 2 pairs km-2. The distribution of body masses and niche characteristics among the bird community is given as well as the sample bias of the mistnet captures.Rare species were a key component of this primary rainforest community. Several patterns of rarity were described and no marked and constant relationships were found between rarity and body size, habitat, diet, foraging behaviour or social system. Among a wide set of environmental constraints, the population of each species may be limited by a different combination of factors. Habitat heterogeneity, low, irregular and seasonal food availability, interspecific competition or heavy predation pressure were prominent and likely causes of the low density of most species which in turn facilitated the high species richness.

The Gulf of Guinea belongs to the most scarcely sampled marine basins in the oceans of the world. We have analyzed diversity and distribution patterns of cumacean communities on the shelf and slope, along the coast of Ghana. The material was collected in October and November of 2012 using a van Veen grab (0.1 m2) on nine transects. Six stations were located at each transect (25, 50, 100, 250, 500, and 1,000 m). Sixty-three species of Cumacea were recorded with Leucon and Eocuma as the most speciose genera, with 12 and eight species, respectively. Comparisons of species richness with literature data pointed that the Ghanaian coast hosts very diverse communities. About 95% of species were new to science, and the number of cumacean species known from the West Africa increased by over 100%. Nevertheless, most of the species had extremely low abundance, 13 singletons and 15 doubletons were found. Mean density of cumaceans was estimated at only 1.5 ind./0.1 m2. Species accumulation curve did not reach the asymptotic level, suggesting undersampling, despite the fact that sampling effort was high (250 samples). The highest species richness was recorded in the inner shelf (25–50 m) and on the slope (1,000 m). Cluster analysis separated shallow water communities from deeper regions on the shelf and upper slope. The most unique species composition was found at 1,000 m. Principal component analysis showed the importance of oxygen, sediments, and human-related disturbance for distribution of cumacean communities. In the shallows, oxygen content and presence of gravel were the most important factors structuring communities. In the deeper bottom areas (250–1,000 m), cumacean fauna was affected by local pollution, mainly by higher concentration of barium, other heavy metals, and THC.

Devotional Texts

This chapter traces how arts of dying migrate from devotional texts into homiletic dramas and finally to the commercial playhouse between 1570 and 1590, around the same time that anti-theatrical condemnations of the stage as inherently blasphemous come to cultural prominence. Theater constitutes an important site of religious instruction and theological investigation not despite, but rather because of, its blasphemous potential. William Wager’s Enough Is as Good as a Feast, Nathaniel Woodes’s The Conflict of Conscience, and Christopher Marlowe’s Doctor Faustus all employ parodies of ars moriendi ideas to represent evil action. Parody arts of dying help dramatize a predestinarian cosmos where distinctions between the elect and the reprobate are fundamental, yet invisible to humans. The bad deaths in these plays function like negative theologies, manifesting and explicating divine will through attempted departures from it. In Doctor Faustus, Marlowe brings the reprobate parodist into focus alongside the divine parodied and makes the magician’s vicious death a site for analyzing human agency. As practices of dying are inverted into theatrical arts of dying badly, Elizabethan dramatists discover occasions to explore the nature of action and the forms of agency available in situations of extreme constraint or privation.

Rich Fauna

The benthic invertebrates of the banks and main channel at 10 sites along 100 km of the lower reach of the La Trobe River, which flows entirely through agricultural and industrial areas, were quantitatively sampled every two months between May 1979 and March 1981; 23 chemical variables were measured concurrently. In all, 337 taxa were collected. Normal and inverse classifications of the faunal data with two similarity indices (Czekanowski, Canberra Metric) indicated that the uppermost two sites (upstream of the industrial areas) with a rich fauna were clearly distinct from the more depauperate downstream sites; these latter sites could be divided into two groups (main channel samples) or four groups (bank samples). In both habitats, eight groups of common (>0.5% of total numbers) taxa were evident: in each habitat, there were one or two groups of resistant taxa abundant at all sites (mostly Chironomidae), one or two groups of opportunistic taxa common at disturbed sites only (Caenidae, Corbiculidae, Ecnomidae, Chironomidae), and two groups of sensitive taxa that were most abundant at the two uppermost sites (Leptophlebiidae, Baetidae, Ecnomidae, Elmidae, Helodidae, Chironomidae, Ceratopogonidae, Hydracanna). Oligochaeta were abundant at all sites and as a group were considered resistant. Multiple discriminant analysis of the previously established site groups with 17 of the chemical variables indicated that high values for conductivity distinguished the most downstream site groups, which had the poorest fauna; the effect of this factor on the fauna was apparently indirect. The analysis also indicated that a decrease in suspended solids at site groups on an impounded section and an increase in nutrients at a site immediately downstream of the input of treated sewage were associated with changes in the fauna. The release of heated water (<25�C) from a power station at one of the sites on the impounded section had little effect on the fauna.

With increasing levels of consensus that sexuality is an important site of social diversity, we are gaining more insight into the detrimental social and psychological effects of sexual repression. Yet, sex continues to be a site shaped by taboo. Personal liberation seems to call for taboobreakers. With that, I ask whether there is anything liberating to learn from the life and work of one of the most notorious violators of sexual and other social mores. I consider the case of the Marquis de Sade (1740-1814). His writing and libertine philosophies were critical of the Catholic Church at a time when dissent was rising. But what made him so radical? Was he merely perceived as a threat by those wanting to protect their power? Or is there something more radically threatening and potentially liberating in his libertinism? What is it about the power of eroticism that makes it so threatening? Can this power be utilized as a tool for empowerment in the context of contemporary social justice struggles, or is it simply violence? I examine how de Sade’s work contributed to a radical counterargument against dominant sexually repressive mores. I conclude with critical remarks and provocative questions about the legacy of his work, which is no less relevant today than it has ever been

In 1921, Carl Biegen found Mycenaean and other ancient sherds at a site then named Souroukla, near Skala in Laconia. William Coulson and others have mistakenly assumed that Souroukla is to be identified as Ayios Stephanos, the important site surveyed by the author in 1956 and later excavated by the British School under Lord William Taylour. The author here reveals that the true identity of Souroukla is the site of Skala: Ayios Nikolaos.To 1921 ο Carl Biegen εντόπνσε μυκηναϊκά και άλλα αρχαία όστρακα στην τότε ονομαζόμενη θέση Σουρούκλα, κοντά στη Σκάλα Λακωνίας.

A checklist of vascular plants of Platberg was compiled to determine species richness, rarity and endemism. The floristic analysis is part of the Department of Economic, Tourism and Environmental Affairs Free State biodiversity assessment programme and conservation management plan for Platberg. The analysis identified a total of 669 species belonging to 304 genera and 95 families, with 214 species belonging to the Monocotyledoneae and 438 species to the Dicotyledoneae. The largest family is Asteraceae with 126 species, followed by Poaceae with 73 species, Cyperaceae with 39 species, Fabaceae with 33 species, and Scrophulariaceae with 27 species. Various fynbos species were found, as well as 26 endemic/near-endemic species belonging to the Drakensberg Alpine Centre or Eastern Mountain Region. The results of this study revealed that Platberg shares inselberg floral richness and endemism that can be tracked via the Afromontane archipelago-like string of inselbergs and mountains, which stretch north through the Chimanimani Mountains, into Malawi, the Eastern Arc Mountains via Tanzania and north through Ethiopia, into Eurasia.Conservation implications: Platberg, as an inselberg, is a site of significant biological diversity, with high species richness, vegetation selection and ecosystem complexity. It shares floral richness and endemism via inselbergs and mountains throughout Africa. The high species richness, Red Data species and ecosystems make this area an important conservation site that should be legislated and protected.

SummaryIn the course of a 13-year study of fall migration of Nearctic-breeding landbirds through a site in the Valle Central of Costa Rica, 5,549 migrant birds of 63 species, and 782 local residents of 28 species, were banded. Arrival dates of migrant species were fairly constant from year to year with passage migrants tending to arrive earlier than winter resident species. Differences in numbers and timing of first-year vs. older birds were noted in some species. Passage migrants showed higher fat deposits than did winter resident species and were virtually never recaptured in succeeding years, indicating a lack of fidelity to specific stopover sites. Winter resident species were recaptured in years following banding at frequencies approaching those for many resident species. Among winter resident species, individuals arriving early had higher fat deposits and were recaptured less frequently than those arriving later; apparently the latter were most likely to remain for the winter in or near the study area. This arrangement probably reduces intraspecific competition between transient and resident individuals of these species. Both at regional and local levels, migrant and local resident species differed in size distributions and to some extent in diet; these differences may reduce competition between these groups. Resident species had generally ceased to nest by the time the migrants arrivedin large numbers, but usually were feeding fledglings and/or moulting, suggesting that the presence of the migrants does not result in a scarcity of resources. The long-term but low-intensity, low-budget nature of this study may make it feasible to duplicate in many areas of the Neotropics, where information is needed regarding effects of land-use changes on resident and migrant avifaunas.
