DISCUSSION “Curve Number Derivation for Watersheds Draining Two Headwater Streams in Lower Coastal Plain South Carolina, USA” by Thomas H. Epps, Dani…
2015
Epps et al. (2013) derived Curve Number (CN) values for two forested headwater watersheds in the Lower Coastal Plain of South Carolina during the 2008-2011 period from rainfall-runoff data, resulting in 23 events for the Upper Debidue Creek (UDC) watershed and in 20 events for Watershed 80 (WS80). D’Asaro and Grillone analyzed the P, CN data of the UDC watershed finding an evident “complacent” behavior, characterized by a declining CN with increasing P but without approaching a stable value at large storms. In this case, the traditional runoff CN equation does not fit well with the rainfall-runoff data that indicate a partial source area watershed behavior and are more aptly modeled by the …
Impiego sicuro delle macchine in bosco.
2012
Dopo una breve rassegna delle principali norme sulla sicurezza e l’ergonomia nei posti di lavoro e sulle macchine, vengono esaminati i principali fattori di rischio presenti nelle operazioni di taglio, allestimento ed esbosco, mettendo in relazione le situazioni di pericolo alle macchine ed alle operazioni svolte. Dall’analisi condotta emerge che un’efficace prevenzione si può realizzare costruendo macchine rispondenti alle norme di ergonomia e sicurezza; effettuando una periodica manutenzione delle stesse e dei relativi dispositivi di sicurezza; istruendo e informando gli operatori sui pericoli e i rischi connessi con i lavori in bosco e sul corretto impiego delle macchine e dei dispositiv…
Reproductive characteristics and differential response to seasonal temperatures of Blue and Great Tits (Cyanistes caeruleus & Parus major) in three n…
2011
The breeding ecology of the Blue Tit (Cyanistes caeruleus) and Great Tit (Parus major) was studied for 18 years in three different neighbouring habitats in Sicily, comprising oakwoods, reforested pine and a reforested mix of pine and broad-leaved trees. Both Blue and Great Tits laid eggs up to two weeks earlier in oakwoods than in the reforested areas. Our results indicate a statistically greater breeding success for both species in the oakwoods compared to reforested habitats, with the mixed reforested habitat having a greater success than that of reforested pine habitat. We also correlated reproductive characteristics with local air temperature to verify if the laying date of tits advance…
New Data on Ichneumonid Hibernation(Hymenoptera: Ichneumonidae)in the Barnova Forest Massif (Iasi County, Romania)
2014
In this paper the authors present the results of their researches made in the period of 2006–2010 on the hibernation of some ichneumonid species in the Bârnova forest massif (Iaşi county). 30 species of ichneumonids (only females) belonging to 20 genera of the the subfamily Ichneumoninae were recorded. Five of these species are new as hibernating. During the studied period there were established 6 hibernating stations, but with a low abundance.
The Embioptera from the Strait of Sicily Islands: first records from Pantelleria and Lampedusa and new data from Lampione (Sicily, Italy)
2021
The occurrence of Embioptera in the Strait of Sicily islands was up to date known only from Lam pione (the smallest of the Pelagie islands), where the only species reported was provisionally assigned to Embia ramburi Rimski-Korsakow, 1905. Based on material recently collected by the authors, the presence of Embioptera is here reported for the first time in the Islands of Pantelleria (Sicily, Trapani) and Lampedusa (Sicily, Agrigento). In the Island of Pantelleria the occurrence of the typical small silky tunnels produced by Embioptera has been verified in many sites, from sea level to Montagna Grande (836 m). In many of these sites, several juveniles and some adult or subadult specimens wer…
