The extracted and purified anthocyanins (Acy) of Vaccinium arboreum Marsh [section Batodendron (Nutt.) Klotzch], commonly called the sparkleberry, were indentified as the 3-monoglycosides of the aglycones delphinidin, petunidin, malvidin, cyanidin, and peonidin with the sugars arabinose, galactose, and glucose (except for cyanidin and malvidin) (or 13 of a potential 15 Acy). Vaccinium arboreum fruit contains Acy which are extremely similar to those reported for the fruits of highbush and lowbush blueberries (subgenus Cyanococcus). Vaccinium arboreum has at least 12 Acy, while those of V. stamineum (subgenus Polycodium), whose geographical range is similar to that of V. arboreum, has only three (monoglycosides of the sugars galactose, arabinose, or glucose with the aglycone cyanidin). If Acy of fruits were to be considered of taxonomic importance, V. arboreum would appear to be more closely associated with subgenus Cyanococcus than with Polycodium which is associated with subgenus Oxycoccus.

Schizaea pectinata (L.) Sw. was collected from the extreme ends of its geographical range in South Africa for a study of sporangial development, sporogenesis and tapetal organisation. Differences were noted in the gross morphology , in sporangium size, spore size and in the patterning of the outer exospore from the two sites. Coiled structures were associated with the development of the inner perispore in spores collected from the Transvaal, whereas dense, heterogeneous bodies were associated with the formation of this layer in spores from the Cape. Differences were also noted in the organisation of the tapetum. A cellular, parietal tapetum and a plasmodial tapetum were present in the Cape material when the spores had developed the sculptured outer exospore. In sporangia from the Transvaal, however, only a plasmodial tapetum was present at the same stage of sporoderm development. A detailed study of S. pectinata throughout its distribution is required to determine the taxonomic importance of these findings.

The paper explores the challenges faced today, in a context of severe economic crisis, by immigrant associations (ΙΜΑs) and Non-Governmental Organizations (NGOs) in Greece. The data analysed here was collected between October 2009 and February 2010 and incorporates references to all recorded migration-related social actors operating in Greece. The paper takes into account such indicators as legal form, objectives, financial capacity and geographical range of activity, concluding with a typology of civil society actors dealing with migration issues. This study aims at informing the migration policymaking and migrant integration processes. By a spatial hot-spot clustering of IMAs and NGOs, we also illustrate the concentration patterns of civil society actors in Greece.

Consumer acceptance of fruit is determined by size, flavour and ripeness. In this study we investigated how altering the carbohydrate supply to Actinidia chinensis var. chinensis ‘Zesy002′ kiwifruit altered the balance between growth and accumulation of metabolites. Canes were phloem girdled and fruit thinned to a leaf-to-fruit ratio (L:F) of either 2 (Low carbohydrate) or 6 (High carbohydrate) at either 38 (Early) or 86 (Late) days after anthesis (DAA) and compared with ungirdled control canes with a L:F of 3. Fruit growth, metabolite accumulation, cytokinin concentrations and maturation were monitored and the sensory attributes of ripe fruit were assessed. The final weight of Early-High and Late-High carbohydrate fruit was 38% and 16% greater compared with control fruit. High carbohydrate fruit had increased starch,soluble sugar and cytokinin concentrations and fruit began to mature earlier and those with a Low carbohydrate had decreased concentrations and matured later compared with control fruit. Control fruit were described by consumers as more acidic and under-ripe compared with those from Early-High carbohydrate canes, but as sweeter than those from Low carbohydrate canes. This study showed that carbohydrate supply can have a major impact on the growth, sugar accumulation and maturity of ‘Zesy002′ fruit sinks.

Abstract The geographical range of many marine species is strongly influenced by the dispersal potential of propagules such as eggs and larvae. Here, we investigate morphological diversity and the effect of body shape on geographical range of leptocephali, the unique, laterally compressed larvae of eels (order Anguilliformes). We used phylogenetically informed analyses to examine the morphological variation of larvae for 17 Eastern Pacific eel species from three adult habitats. We also investigated whether morphological traits of leptocephali could predict larval latitudinal range, hypothesizing that body shape may influence passive dispersal via currents. We found that no two species shared the same multivariate growth trajectories, with the size and scaling of pectoral fin length and snout-to-anus length being particularly variable. Larvae with longer relative predorsal and snout-to-anus lengths at median sizes exhibited wider larval geographical ranges. Body aspect ratio and maximum body length at metamorphosis, two traits we hypothesized to be important for passive transport, were not significant predictors of maximal larval range. We discovered an increase in phylogenetic signal over larval development as eels approach metamorphosis, potentially due to similar selective pressures between related species (such as juvenile habitat or adult morphology). Lastly, we conclude that larval body shape is probably influenced by adult habitat and adult morphology.

Hinde's Babbler Turdoides hindei is a globally threatened Kenyan endemic, which during the 1990s, was known from just seven localities. Based mainly on surveys undertaken in 2000–2001, we estimate the species's global population size and compare recent changes in its “extent of occurrence” and “area of occupancy”. Historically, Hinde's Babbler has been recorded from c. 40 10 × 10 km squares; 27 pre-1980 and 19 subsequently, suggesting that its area of occupancy has declined by about 30%. In contrast, its extent of occurrence has declined by only 8%, this measure being less sensitive to the balance of gains and losses occurring near the centre of its range. During surveys in 1994 and 2000–2001, 157 groups were located, containing 665 birds, 75% of which were found at two intensively cultivated sites. Some 97% of birds were located in, or adjacent to, five Important Bird Areas, but only 8% were found within legally protected areas. Two extrapolated population estimates are presented, based on the number of birds likely to have been missed at survey sites, and the species' area of occupancy. These suggest that the global population of Hinde's Babbler is likely to fall within the range of 1,500–5,600 birds.

F1 hybrids of the nor non-ripening mutant tomato in different genotypic backgrounds were evaluated between 1978-81. The nor gene in the heterozygous condition delayed the start of ripening by a few days, increased the interval between breaker and the table ripe stage to 10 d at 21�C compared with 6 d for fixed cultivars and increased the storage life of ripe fruit at 21�C by about 50%. The retention of firmness by ripe fruit of the hybrids was affected by parental genotype. Fruit of some hybrids was firmer or as firm as fruit of the hard commercial Flora-Dade but others were much softer. A major problem with fruit of F1 nor hybrids was poor colour development. The fruit ripened to an orange-red colour, and strains with green shoulders developed an unattractive yellow on the shoulders. This deficiency was most pronounced in fruit picked before the appearance of red colour. The best hybrid found in this study was 75T10-1 x nor backcross 4 or 5 Heinz 1350. Fruit size, soluble solids, pH, titratable acidity, total ascorbic acid levels and acceptability except external colour of table ripe fruit appeared to be influenced by the parental genotype rather than by the nor gene. Since there were marked differences between hybrids with different genotypic backgrounds, it should be possible to breed nor hybrids with improved colour and firmness.
