Data from: Effects of undergrowth removal and edge proximity on ground beetles and vascular plants in urban boreal forests
2019
Urban forests are regularly managed for human safety and aesthetic reasons, but they are crucial habitat for many species. Removals of undergrowth occur commonly in these forests, yet the ecological consequences of these operations are poorly understood. We sampled ground beetles (Coleoptera, Carabidae) and vascular plants along 20-m edge gradients in Finnish urban forests, in five stands treated 0.5−2.5 years earlier with undergrowth removal and in five untreated stands. We hypothesized that undergrowth removal and edge proximity would benefit opportunistic and open-habitat species, whereas shady-habitat species would be affected negatively.

Let me in. Visioni architettoniche per habitat multispecie
2020
I disegni di Alessandro Melis sono lo spunto per una descrizione interpretativa, orientata a mettere in luce l’espressione di un nuovo rapporto fra uomo e non umani come tema dell’architettura contemporanea. L’immaginario che agisce nei disegni esaminati predispone, come sempre in architettura, lo scenario di fondo cui prepararsi per i reali interventi disciplinari. La ripresa degli organi zoomorfi o delle macchine tecno-sensoriali di Coop Himmel(b)lau, a loro volta eco delle prime introduzioni di Archigram, del bowellism di Frederick Kiesler, dei sistemi viventi di Hans Hollein, prolunga nel contemporaneo l’eco di una ricerca di apertura del campo disciplinare. La novità, nella frontiera v…

Paesaggio Scotellaro. Materiali per "Cantilena" (e per la prima Rosselli)
2023
The article starts from the intellectual friendship between Rocco Scotellaro and Amelia Rosselli, then proceeds to focus on the early poems by Rosselli (specifically Cantilena. Poesie per Rocco Scotellaro). Rosselli's short poetic text, her Italian debut in 1953, displays the mourning for Scotellaro's early death and portrays a contradictory absence/presence of her friend into the landscape of Basilicata. In our contribution a theme-based analysis is offered. Through close reading, we investigate on Rosselli's sources (Campana, Jung), both identifying cross-references to Scotellaro's poems and proses and reading Cantilena in continuity with her poetic texts up to Diario ottuso.
I suoni di Amelia
2008
Amelia Rosselli (1930-1996) è stata una delle voci più originali della poesia italiana del secondo dopoguerra. La sua prima vocazione fu quella musicale, cui dovette rinunciare per un combinato di eventi; ma la musica è rimasta un continuo riferimento in tutta la sua produzione poetica. Il saggio inizialmente ricostruisce la formazione e la produzione critica in campo musicale di Amelia Rosselli, per poi identificare nella sua poesia la cifra squisitamente musicale.
CyaC, a redox-regulated adenylate cyclase of Sinorhizobium meliloti with a quinone responsive diheme-B membrane anchor domain.
2019
The nucleotide cyclase CyaC of Sinorhizobium meliloti is a member of class III adenylate cyclases (AC), a diverse group present in all forms of life. CyaC is membrane-integral by a hexahelical membrane domain (6TM) with the basic topology of mammalian ACs. The 6TM domain of CyaC contains a tetra-histidine signature that is universally present in the membrane anchors of bacterial diheme-B succinate-quinone oxidoreductases. Heterologous expression of cyaC imparted activity for cAMP formation from ATP to Escherichia coli, whereas guanylate cyclase activity was not detectable. Detergent solubilized and purified CyaC was a diheme-B protein and carried a binuclear iron-sulfur cluster. Single poin…
THE DIASCIA FLOWER AND ITS BEE - AN OIL-BASED SYMBIOSIS IN SOUTHERN AFRICA
1984
As has been formerly shown, the double-spurred flowers of the South African genus Diascia (Scrophulariaceae) produce fatty oil as a primary attractant. Their oil-collecting pollinators have so far remained unknown. It is concluded from the morphology and from direct evidence of flower visitation that the recently established Melittid genus Rediviva represents the co-evolved pollinator group of these plants, at the same time demonstrating the presence of “manual” oil collectors in Southern Africa. The bees must introduce their especially equipped forelegs into the paired spurs of Diascia for harvesting the oil, thereby pollinating the flower. In the described case, a new species, Rediviva em…
Identification of Novel Hexapeptides Bioactive against Phytopathogenic Fungi through Screening of a Synthetic Peptide Combinatorial Library
2002
The purpose of the present study was to improve the antifungal activity against selected phytopathogenic fungi of the previously identified hexapeptide PAF19. We describe some properties of a set of novel synthetic hexapeptides whose D-amino acid sequences were obtained through screening of a synthetic peptide combinatorial library in a positional scanning format. As a result of the screening, 12 putative bioactive peptides were identified, synthesized, and assayed. The peptides PAF26 (Ac-rkkwfw-NH(2)), PAF32 (Ac-rkwhfw-NH(2)), and PAF34 (Ac-rkwlfw-NH(2)) showed stronger activity than PAF19 against isolates of Penicillium digitatum, Penicillium italicum, and Botrytis cinerea. PAF26 and PAF3…
Herbicidal potential of aqueous extracts from Melia azedarach L., Artemisia arborescens L., Rhus coriaria L. and Lantana camara L.
2017
In the search for new strategies for weed management in agricultural systems, a great interest is to use the plant extracts to replace or integrate, chemical weed control. Two experiments were done to test the effects of plant water extracts from Chinaberry (Melia azedarach L.), Tree Wormwood (Artemisia arborescens (Vaill.) L.), Sicilian Sumac (Rhus coriaria L.) and Lantana (Lantana camara L.) on seed germination of Rocket (Eruca sativa Mill.), Rapeseed (Brassica napus L.), Bladderflower (Araujia sericifera Brot.) and Psyllium (Plantago psyllium L). The water extracts (pure and 50% mixtures) from the donor species were applied on seeds of recipient plants. In second experiment in pots, thes…
