The phytosociology and ecology of Scorzonera parviflora stands were studied in the Pannonian Basin and Western Balkans. In total, we used 60 relevés (46 collected for this study and 14 from the literature) for the ordination analysis. Optimal conditions for S. parviflora are species-poor coastal habitats in regions with hot summers and with high soil salinity and nutrient-richness. The species reached high cover values in most cases (25–50%) and it often dominated the stand. The classification of phytosociological data shows four floristically and ecologicaly well characterized clusters. Cluster 1 was identified as the rare association Junco maritimi-Scorzoneretum parviflorae, sampled only in coastal Croatia (on the island of Pag) and inland Hungary (Fertőszéplak). Cluster 2 groups meadow-like salt marsh vegetation in transition between two vegetation types, Limonio narbonensis-Puccinellietum festuciformis and Trifolio-Hordeetum secalini. Cluster 3 represents the typical variant of the Scorzonero parviflorae-Juncetum gerardii, while cluster 4 was determined as a variant with Tripolium pannonicum of the Scorzonero parviflorae-Juncetum gerardii characterized by a higher presence of obligate halophytes (Tripolium pannonicum, Puccinellia distans agg. and Plantago maritima) than in cluster 3. Our study shows that vegetation with Scorzonera parviflora in inland Central and SE Europe belongs to the Juncion gerardii and stands of coastal Croatia are related to the Juncion maritimi alliance. The species composition and the classification of the examined stands in the Pannonian and Transylvanian basins were influenced more by abiotic environmental factors than by current management.

African forests within the Congo Basin are generally mapped at a regional scale as broad-leaved evergreen forests, with the main distinction being between terra-firme and swamp forest types. At the same time, commercial forest inventories, as well as national maps, have highlighted a strong spatial heterogeneity of forest types. A detailed vegetation map generated using consistent methods is needed to inform decision makers about spatial forest organization and their relationships with environmental drivers in the context of global change. We propose a multi-temporal remotely sensed data approach to characterize vegetation types using vegetation index annual profiles. The classifications identified 22 vegetation types (six savannas, two swamp forests, 14 forest types) improving existing vegetation maps. Among forest types, we showed strong variations in stand structure and deciduousness, identifying (i) two blocks of dense evergreen forests located in the western part of the study area and in the central part on sandy soils; (ii) semi-deciduous forests are located in the Sangha River interval which has experienced past fragmentation and human activities. For all vegetation types enhanced vegetation index profiles were highly seasonal and strongly correlated to rainfall and to a lesser extent, to light regimes. These results are of importance to predict spatial variations of carbon stocks and fluxes, because evergreen/deciduous forests (i) have contrasted annual dynamics of photosynthetic activity and foliar water content and (ii) differ in community dynamics and ecosystem processes.

The Morro de Fumaça, Município de Torixoreu, Mato Grosso, Brazil, is a low hill characteristic of a range of similar topographic features in the region. It shows a suite of representative and rapidly disappearing vegetation types together with their associated soils. The upper slopes are clothed in deciduous forest, which is followed downslope by a band of mesotrophic facies cerradão and then on the lower ground by more open cerrado. The parallel changes in soil pass from the shallow and frequently plinthitic lithosols over the summits and upper slopes to progressively deeper and more acidic soils over the footslope. The increasing impoverishment from upslope sites downwards is especially marked by the changes in the exchangeable calcium content. The vegetation survey was done by means of point-centred quarter transects and by quadrats. The tree species of the deciduous forest are listed. Both the forest and mesotrophic facies cerradão closely resemble in floristics, structure and soil characteristics those studied in the limited investigations available from other areas of Mato Grosso and elsewhere in Central Brazil. The soil data are derived from an initial reconnaissance survey, with soil profiles selected to represent the major changes in vegetation. Extremely little information exists on the deciduous forests of Brazil and the present communication provides information on this important and increasingly endangered type of vegetation.

Abstract A phytosociological survey was carried out in a poorly known travertine area of southern Tuscany harbouring a rich vegetation mosaic with chamaephytic garrigues, species-rich xerophytic grasslands, chasmophytic coenoses, annual species-dominated communities, shrublands and thermophilous deciduous forests. Field sampling and data analysis allowed to identify and characterize several community types, some of which of significant interest due to their ecological specificity and rarity in peninsular Italy. In particular, our data confirm the associations Pistacio terebinthi-Paliuretum spinosae and Pistacio terebinthi-Quercetum pubescentis, respectively a shrub and forest community type previously unknown for Tuscany. In addition, a new therophytic association of travertine debris named Sedetum hispanico-caespitosi and placed in the Hypochoerion achyrophori alliance (Brachypodietalia distachyi order, Tuberarietea class) is also described. Finally, dynamic relationships between the vegetation types are highlighted and the presence of conservation priority habitats in the area are pointed out.

AbstractThe deciduous forests represent dominant natural vegetation of Central European landscape and an important functional component for maintenance of biological diversity. However, their syntaxonomy and ecological gradients still remain unclear. The numerical classification was conducted to determine the main units of forest vegetation, while ordination techniques were used to explain the structure of vegetation-environmental data matrix consisting of 110 forest stands in the Štiavnické vrchy Mts (central Slovakia). Ten vegetation types within the phytosociological classes of deciduous forests Quercetea robori-petraeae and Querco-Fagetea were distinguished. The major environmental driver responsible for variation in forest species composition was interpreted as a response to soil moisture which also accounted for a large part of species variability (3.74%). Soil nutrient/acidity complex expressed by pH, Ca and Al concentration was also an important source of vegetation variability. Relevance of soil conditions in relation to plant survival and community distribution was discussed. Along the soil moisture gradient, vegetation types were arranged from the subxerophilous oak forests through the mesophilous beech and ravine forests to the hygrophilous alder ash vegetation.

Breakfast Skipping

Abstract.Aim: To assess the association of breakfast skipping with overweight and obesity among children in Albania, a post-communist country in the Western Balkans, which is undergoing a long and difficult political and socioeconomic transition towards a market-oriented economy. Methods: A nationwide cross-sectional study was carried out in Albania in 2013 including a representative sample of 5810 children aged 7.0 – 9.9 years (49.5% girls aged 8.4 ± 0.6 years and 51.5% boys aged 8.5 ± 0.6 years; overall response rate: 97%). Children were measured for height and weight, and body mass index (BMI) calculated. Cut-off BMI values of the World Health Organization (WHO) and the International Obesity Task Force (IOTF) were used to define overweight and obesity in children. Demographic data were also collected. Results: Upon adjustment for age, sex, and place of residence, breakfast skipping was positively related to obesity (WHO criteria: OR = 1.5, 95% CI = 1.3–1.9; IOTF criteria: OR = 1.9, 95% CI = 1.4–2.5), but not overweight (OR = 1.1, 95% CI = 0.9–1.3 and OR = 1.1, 95% CI = 0.9–1.4, respectively). Furthermore, breakfast skipping was associated with a higher BMI (multivariable-adjusted OR = 1.05, 95% CI = 1.02–1.07). Conclusions: Our findings point to a strong and consistent positive relationship between breakfast skipping and obesity, but not overweight, among children in this transitional southeastern European population. Future studies in Albania and other transitional settings should prospectively examine the causal role of breakfast skipping in the development of overweight and obesity.

A New Species

Abstract—A new species of Eugenia from the Atlantic forest of Brazil is described and illustrated. Eugenia flavicarpa is restricted to the Floresta de Tabuleiro (lowland forests) of Espírito Santo state and is nested in Eugenia subg. Pseudeugenia. Considering all other species of the subgenus that occur in forest vegetation types of the Atlantic forest phytogeographic domain, Eugenia flavicarpa can be distinguished mainly by the combination of smooth leaves with indumentum on both surfaces, with two marginal veins, usually ramiflorous inflorescences, pedicels 4.5‐9.7 mm long, flower buds 3.5‐4 mm in diameter, and by the calyx lobes that are 2‐3 mm long with rounded to obtuse apices. Morphological analyses were performed to explore the significance of quantitative diagnostic features between the new species and the closely related species, Eugenia farneyi. Notes on the habitat, distribution, phenology, and conservation status of Eugenia flavicarpa are provided, as well as a key for all species of Eugenia subg. Pseudeugenia from forest vegetation of the Atlantic forest phytogeographic domain.
