(Z)-1-Chloro-1-[2-(2-nitrophenyl)hydrazinylidene]propan-2-one
2012
The title molecule, C9H8ClN3O3, lies on a mirror plane. Intramolecular N—H...O and N—H...Cl hydrogen bonds occur. One of the nitro O atoms is disordered (site occupancy ratio = 0.40:0.10).
Data from: Ecological niche features override biological traits and taxonomic relatedness as predictors of occupancy and abundance in lake littoral m…
2018
The degree to which species ecological and biological traits determine their distribution and abundance has intrigued ecologists for a long time, and it has seen a revival in recent years. This topic is important because it provides information about the determinants of species rarity and their conservation implications. We examined the effects of niche breadth, niche position, biological traits and taxonomic relatedness on the interspecific occupancy-abundance relationship, as well as on occupancy and abundance, in lake littoral macroinvertebrates. We sampled 48 lakes in a boreal lake district, found altogether 155 species, and calculated regional occupancy (as the proportion of sites occu…
Sociologia e urbanistica, dalle diseguaglianze agli spazi condivisi
2011
Poichè nuove società, geografie ed economie riconfigurano città e territori attuali, il contributo auspica un ritorno concreto al binomio urbanistica/sociologia affinchè le forme spaziali pianificate traducano concretamente le questioni di giustizia ed equità richieste dall’abitare contemporaneo. Poichè nuove società, geografie ed economie riconfigurano città e territori attuali, il contributo auspica un ritorno concreto allo storico binomio urbanistica/sociologia, affinchè le forme spaziali pianificate traducano concretamente le questioni di giustizia ed equità richieste dall’abitare contemporaneo. Nello specifico viene proposta l'applicazione - anche a contesti urbani - della Post Occupan…
Niche position drives interspecific variation in occupancy and abundance in a highly-connected lake system
2019
Highlights • We studied interspecific variation in occupancy and abundance of freshwater species. • Occupancy and abundance correlated positively for both diatoms and macroinvertebrates. • Niche position had clearest effects on variation in occupancy and abundance. • The more marginal the niche position, the rarer a species is. We examined how niche position, niche breadth, biological traits and taxonomic relatedness affect interspecific variation in occupancy and abundance of two commonly-used biological indicator groups, i.e. diatoms and macroinvertebrates. We studied 291 diatom and 103 macroinvertebrate species that occupied the littoral zones of a large (305 km2) highly-connected freshw…
