This might be related to the mobility of the species, which can easily cross the road, as well as low local forestry pressure. explaining 27 and 26 % of between-plot diversity at family and taxa levels, respectively, while the transect effect accounted for almost all the spatial effects, i.e. seja mais alto nas planícies arenosas, e em partes dos complexos de chapadões e de Right column mean per site of plot scores along axes 1–3, projected on maps, ariables tested to explain diversity patterns and spatial patterns in floristic composition of French Guiana forest at multiple scales, Central panel projection of plot (grey points) and taxa (black circles) scores on the 2 main axes of the NSCA on the taxa-by-plot abundance table—circle size is proportional to taxa abundance. Tree species diversity and carbon stocks were positively related, implying a potential functional relationship between the two, and a ‘win–win’ scenario for conservation; however, lower biomass areas also contain diverse species assemblages meaning that carbon-oriented conservation may miss important areas of biodiversity. (2007) The TRMM Multisatellite Precipitation Analysis (TMPA): quasi-global, multi-, year, combined-sensor precipitation estimates at fine scales. J Stat Softw, Dray S et al. Despite recent progress in the analysis and modeling of species diversity (Elith et al. A preview of this full-text is provided by Springer Nature. In the upper horizons, due to the even more extreme water regime, organic material uptake and biological activity, the constituents continue to be weathered and undergo substantial remodelling; a major mechanism is iron depletion that varies considerably depending on the topography, sometimes to the extent of being wholly eliminated by podzolisation. 2011), Central panel projection of plot (points) and family scores (circles) on the 3 main axes of the NSCA with the family-by-plot abundance table—circle size is proportional to abundance and grey levels indicate family position on axis 3—only the families with the greatest contributions are indicated. These results indicate that the vocal activity of a key conservation species can be monitored automatically in a non-invasive way. This museum is distinctive and differentiated from the regular museums for its exhibition of time and space: it is a museum of time due to its focus on particular and defined historical sectors, while following an extensive period spanning from the past right to the present day; a, Das Ökomuseum unterscheidet sich von anderen Museen, da es ein Museum der Zeit und des Raumes ist: der Zeit, das es besondere und definierte historische Bereiche vorzieht, es wird eine lange Periode dargestellt, von der Vergangenheit bis hin in die heutige Zeit; des Raumes, da, By declaring it an Espacio Natural Protegido Andaluz (Protected Nature Area of Andalusia) in 1929, a Parque Natural (Nature Park) in 1978 and finally a Paraje Natural (Nature Area) in 1989 the Administration has only taken note of something that is obvious at first sight: the enormous value of this, Bereits im Jahr 1929 wurde dieses Gebiet als geschützte Landschaft eingestuft, 1978 zum Naturpark und schließlich 1989 zum Landschaftsschutzgebiet deklariert, womit die Regierung nichts anderes getan hat, als zu bestätigen, was ohnehin auf den ersten, Blick augenfällig wird: Der enorme Reichtum der, When drawing up and revising the programmes of measures pursuant to paragraph 1, Member States shall give due consideration to the social and economic impacts of the, measures envisaged, as well as the impact on safety and on, Die Mitgliedstaaten tragen bei der Erstellung und Revision der Maßnahmenprogramme nach Absatz 1 den gesellschaftlichen und wirtschaftlichen Auswirkungen der geplanten Maßnahmen sowie, deren Folgen für die Sicherheit und für unser, (d) an assessment of the potential adverse consequences of future floods for human health, the environment, cultural heritage and economic activity, taking into account as far as possible issues such as the topography, the.

We also introduced two layers commonly used as references for pr, spp. All the plots were georeferenced using a Garmin 76CSx GPS receiver (Garmin Ltd., Southampton, UK) and delineated in the field using a Vertex laser clinometer (Haglo, Sweden AB, Langsele, Sweden). 40 pp ISBN 92-894-7496-3.

We deployed nine acoustic recorders over 29 days along a road that connects French Guiana to Brazil. This contribution explores the information provided by the landscape transformation occurred during the intense period of Roman gold mining activity in northwest Spain. present new inventory data from south-eastern Tanzania, comprising more than 15,000 trees at 25 locations located across a gradient of aboveground woody carbon (AGC) stocks.

Extending over approximately 85,000 km 2 , the predominantly flat relief of French Guiana is dissected by rivers and comprises two main geographical regions: a coastal strip with savannas and mangroves, and a dense tropical forest that covers almost 95% of the territory (Thiollay 1989;Guitet et al. Because of its influence on soil, geology often has a significant impact on tropical forest, vegetation, particularly when geological substrates with very dissimilar ages or properties, chemical properties on species composition, geology is sometimes recognized as influ-. A geomorphological study will provides a conceptual picture of coastal processes and the potential behaviour of the coastal system. whereas current climatic conditions are not (Stropp et al.

Overdispersion occurs either in least seasonal and more stable forests or in high elevation ecosystems; in the former case, this could be ascribed to ecological diversification over the long term and conservation of old lineages in refugia, and in the latter, to the assemblage of species pools of distinct biogeographic and evolutionary backgrounds (temperate and tropical). tropical tree diversity indices from forestry surveys: a method to integrate taxonomic uncertainty.

We also show that a forest stratification based on this surrogate more, efficiently captures variations in composition than expert- or remote sensing-based, approaches as it explains a larger proportion of floristic variations and especially the, Previous botanical studies identified two forest types in French Guiana, a Caesalpi-, nioideae-dominated forest assumed to be in the north, and a Burseraceae-dominated forest, assumed to cover the south (Sabatier and Pre, by geomorphological landscapes expands on this distinction for taxa corresponding to, more than 65 % of all individuals, including. families (Tab. Most studies analyzing plot taxonomic data along broad gradients concluded that tropical tree species turnover is partly shaped by climate through rainfall, temperature and seasonality gradients (Swaine, 1996;Pyke et al., 2001;Engelbrecht et al., 2007;Parmentier et al., 2007;Toledo et al., 2011Toledo et al., , 2012Amissah et al., 2014).

Le phosphore, le contenu en argile et le taux de saturation sont extrêmement variables entre les parcelles et impactent la richesse et la composition des communautés d’arbres. Land use dynamics between 1990 and 2005 were studied overlaying Portuguese Land Use Map (1990) and the Portuguese National Forest Inventory (2005). showed that the site effect accounted for more than two-thirds of the spatial effects.
