Gli annali tipografici in Italia e l'eredità di Barberi
No full textIl contributo esamina il ruolo di Francesco Barberi nell'elaborazione di un contributo alla teoria bibliografica italiana in materia di annali tipografici, partendo dal primo lavoro su Paolo Manuzio per arrivare agli ultimi contributi scientificie e alle ultime riflessioni dell'autore negli anni Ottanta del Novecent
Variation in Eucalyptus barberi L. Johnson & Blaxell
No full textPhenetic variation within Eucalyptus barberi L. Johnson & Blaxell was examined and compared to related Tasmanian species. "Typical" northern populations were morphologically distinct from the more diverse group of populations to the south. This phenetic disjunction did not correspond to the major geographic disjunction in the range of E. barberi. Detailed study of two morphologically aberrant population indicated that they probably arose from in situ hybridisation: however, the exact identities of the progenitor species remains unclear. The type locality and several of the "southern" populations, as well as aberrant populations at Meredith Tier and Ponybottom Creek, deserve formal conservation

"Typical" northern populations were morphologically distinct from the more diverse group of populations to the south. This phenetic disjunction did not correspond to the major geographic disjunction in the range of E. barberi. Derailed study of two morphologically aberrant populations indicated that they probably arose from in situ hybridisation; however, the exact identities of the progenitor species remains unclear. The type locality and several of the "southern" populations, as well as aberrant populations at Meredith Tier and Ponybottom Creek, deserve formal conservation

Direct weed suppression by cover crops and residual effects on grain maize and sunflower
No full textWe investigated the weed suppression potential of different winter cover crops grown alone or in mixtures during the cover crop growing cycle and in subsequent grain maize and sunflower. A plot trial was conducted in 2005-06 and 2006-07 at CIRAA (University of Pisa, Italy). The experiment was laid out as an RCB design. Data were subjected to ANOVA and subsequent LSD test at P ≤ 0.05 for mean separation. In both years there were significant differences between treatments in terms of cover crop and weed biomass. Leguminous cover crops produced the highest biomass, especially Vicia villosa when grown alone (5.3 and 5.7 t ha-1 in 2006 and 2007 respectively). In 2007 also cover crop mixtures gave good results with a mean biomass of 6.9 t ha-1. Mixtures were the most weed suppressive cover crops in both years, yielding on average 0.3 and 0.2 t ha-1 total weed biomass compared to an overall mean of 0.9 and 1.1 t ha-1 in 2006 and 2007 respectively. In both years, we registered the highest cash crop grain yield when maize or sunflower followed V. villosa or the mixtures including a leguminous cover crop. There were significant differences among treatments in terms of total weed biomass in the subsequent cash crops in 2006 but not in 2007. In sunflower, the lowest total final weed biomass was observed after the Avena sativa cover crop (0.4 t ha-1) whereas in maize the lowest weed biomass was observed after V. villosa (0.3 t ha-1)
Changes in spectral properties of ageing and senescing maize and sunflower leaves
No full textThe objective of this study was to determine the differences between maize (Zea mays L.) and sunflower (Helianthus annuus L.) in the pattern of leaf chlorophyll content and spectral properties occurring with leaf ageing and senescence. Chlorophyll accumulation and leaf spectral properties were determined in growing and senescing leaves of field-grown maize and sunflower hybrids. Measurements were taken at intervals of 3–4 days during the rapid stem elongation phase on leaf 11 for maize and leaf 17 for sunflower. Reflectance (R) and transmittance (T) spectra of adaxial surfaces of attached leaves were measured using a LI-COR 1800 hand-held spectroradiometer with an external integrating sphere, over the wavelength range from 400 to 100 nm. Absorptance (A) was computed as: A = 100-(R + T). In the growing leaf, chlorophyll content increased until full leaf expansion, while no changes in A and T were recorded. After full leaf expansion was reached, chlorophyll dropped from 514.3 to 328.0 μmol m−2 in maize and from 527.2 to 164.1 μmol m−2 in sunflower. Absorptance in the PAR region declined about 5% in maize and about 11% in sunflower and T increased about 1% in maize and 7% in sunflower. Within the PAR region, variations in A and T were recorded only in the green band (520–600 nm) for maize and in the green and red (630–690 nm) bands for sunflower. There were differences between maize and sunflower in the relative timing of the decrease in chlorophyll content and A in senescing leaves: maize retained chlorophyll longer than sunflower and A declined more slowly in maize as a result of the different length of leaf maturity and senescing stages

Cryptic diversity in Zoraptera: Latinozoros barberi (Gurney, 1938) is a complex of at least three species (Zoraptera: Spiralizoridae).
No full textThe order Zoraptera contains relatively few species, but current molecular phylogenetic studies suggest an unexpectedly high level of cryptic diversity in the order with many overlooked species based on morphology alone. Latinozoros Kukalova-Peck & Peck, 1993 represents the only genus of monotypic Latinozorinae (Zoraptera: Spiralizoridae) with only one species described, L. barberi (Gurney, 1938), until now. Although this species has been repeatedly reported from a number of locations in South and Central America, it is likely a complex of unrecognized species. Here, we present a molecular phylogenetic reconstruction revealing three genetically distinct lineages in Latinozoros, and we also present detailed morphological comparisons that prove the species status of Latinozoros cacaoensis sp. nov. from French Guiana and L. gimmeli sp. nov. from the Dominican Republic, Trinidad and Panama. The results indicate that the species previously referred to L. barberi is actually a species complex that includes L. barberi, the new species described here, and perhaps other species
