A novel ecotype of Petunia integrifolia subsp. integrifolia var. depauperata with glabrous leaves was found near the town of Torres, Brazil, and hybridized with P. ×hybrida. In the F1 and F2 generations, the glabrous leaf trait was quantitatively inherited with high heritability. The absence of trichomes was not associated with the decrease in the resistance of the glabrous-leaved species and hybrids to aphids, but was correlated with a lower resistance to spider mites.

Abstract This paper presents results of studies conducted in the forest areas of the Polesie National Park and in the surroundings of the chemical producer Zakłady Azotowe in the town of Puławy on the abundance of mites from the families Tetranychidae and Phytoseiidae. These studies were conducted on eight different sites in the years 2002–2004 and aimed at answering the question of whether mite abundance is related to factors such as area, site and year. In total, 8894 specimen of the spider mite family and 1835 specimen of the predatory mite family were collected. Spider mites were more abundant in Puławy than in the Polesie National Park, whilst the abundances of predatory mites were similar in both study areas. For spider mites, statistically significant differences were found in terms of study area and site, but also in terms of the study area in relation to the year of investigation. In the case of predatory mites, statistically significant differences were also found in terms of the study area in relation to the year of investigation.

The sequence of the intron within the chalcone synthase A gene (ChsA) was used to characterize Petunia integrifolia subsp. integrifolia var. depauperata (Fries) Smith et Downs, P. altiplana Ando et Hashimoto, P. littoralis Smith et Downs, and an unknown taxon from the town of Torres in Brazil. Based upon the intron, the Torres taxon most closely resembled P. integrifolia. The unrooted phylogenetic tree suggested that P. integrifolia was more closely related to P. littoralis than P. altiplana.

The title of this text, From the Book of Madness and Atrocity, published here for the first time, indicates its generic and stylistic specificity, its fragmentary, incomplete character. It suggests that this text is part of a greater whole, still incomplete, or one that cannot be grasped. In this sense Śreniowski refers to the topos of inexpressibility of the Holocaust experience. The text is reflective in character, full of metaphor, and its modernist style does not shun pathos. Thus we have here meditations emanating a poetic aura, not a report or an account of events. The author emphasises the desperate loneliness of the dying, their solitude, the incommensurability of the ghetto experience and that of the occupation, and the lack of a common fate of the Jews and the Poles (“A Deserted Town in a Living Capital”; “A Town within a Town”; “And the Capital? A Capital, in which the town of a death is dying . . . ? Well, the Capital is living a normal life. Under the occupation, indeed . . . .”).

This article tackles the relationship between Turkish-Belgian families with the Flemish society, within the specific context of their experiences with early childhood education and care (ECEC) system in Flanders. Our findings are based on a focus group with mothers in the town of Beringen. The intercultural dimension of the relationships between these families and ECEC services is discussed using the Interactive Acculturation Model (IAM). The acculturation patterns are discussed under three main headlines: language acquisition, social interaction and maternal employment. Within the context of IAM, our findings point to some degree of separationism of Turkish-Belgian families, while they perceive the Flemish majority to have an assimilationist attitude. This combination suggests a conflictual type of interaction. However, both parties also display some traits of integrationism, which points to the domain-specificity of interactive acculturation.

False spider mites are serious pests of pomegranate and frequently cause considerable economic losses in other fruit crops as well. A field experiment conducted to evaluate eleven acaricides against Tenuipalpus aboharensis infesting pomegranate plants, revealed that wettable sulphur at 2.5 g and dicofol at 2.5 ml per litre were very effective and other acaricides viz. propargite, fenpyroximate, chlorfenapyr and buprofezin were also found effective against T. aboharensis.

In his famously disparaging poetic retorts to the poetry of the British Della Cruscan movement, the Baviad and Mæviad, Tory satirist William Gifford made every effort to separate the readers of Della Cruscan poetry into two distinct audiences: Della Cruscan ‘writer-readers’ who read and actively responded to pieces written by other members of the coterie with poetry of their own, and the non-participating mass audience. According to Gifford, this latter audience – metonymized as ‘the Town’ in the Baviad – ignorantly follows the whims of fashion, absorbing Della Cruscan poetry, but never actually responding to it. Through an analysis of both Della Cruscan poetry and Gifford's retorts, this essay aims to re-establish the links between these two kinds of audiences. I will argue that Gifford's attempts to suppress these links stemmed from a deep-seated fear – fuelled by post-Revolutionary political instability – that the Della Cruscan coterie offered a platform whereby members of the mass reading audience could join their poetic conversations pseudonymously, and ultimately be granted a voice, regardless of their gender or political affiliations.

This essay is the first to examine Melville’s “The Town-Ho’s Story” (Chapter 54 of Moby-Dick [1851]) in relation to W. B. Stevenson’s then-popular-but-now-forgotten British travel narrative, Twenty Years’ Residence in South America (1825). Drawing from suggestive circumstances and parallel action unfolding in each, I make a case for the English sailor’s encounter with the Spanish Inquisition in Lima as important source material for the Limanian setting that frames Melville’s tale. In bringing to light a new source for Moby-Dick, I argue that Melville refracts Stevenson’s actual encounter with the Inquisition in Lima to produce a symbolic, mock confrontation with Old-World authority represented in the inquisitorial Dons and the overall context of the story. Thus, the purpose of the essay is twofold: first, to recover an elusive source for understanding the allusive framework of “The Town-Ho’s Story,” a setting that has perplexed some of Melville’s best critics; and second, to illuminate Melville’s use of Lima and the Inquisition as tropes crucial for understanding a larger symbolic confrontation between the modern citizen (or subject) and despotic authority that plays out not only in Moby-Dick but also in other works such as Mardi (1849), White-Jacket (1850), “Benito Cereno” (1855), Clarel (1876), and The Confidence-Man (1857), wherein the last of which the author wrote on the frontispiece of a personal copy, “Dedicated to Victims of Auto da Fe.”
