In bare dolines grass associations seemingly homogeneous in their habitat and rich in number of species act as indicators of the specific ecological conditions of the various slopes. For the differences of species on the SW and NE slopes water
The AA. use an island specific presence/absence data set for the Canary Islands' Arthropoda, Spermatophyta, Fungi, Lichenes, Bryophyta, Mollusca, Chordata, Pteridophyta, Annelida and Nematoda to assess the relative influence of environmental
and historical factors on species distribution and endemism. Species richness and the percentage of island endemic species as well as similarity indices for island comparisons were calculated for all species groups. The pattern of species richness is best
explained by island elevation. A similar pattern is detected for the percentage of single island endemics (pSIE), a factor associated with speciation. Thus, the AA. conclude that correlations between species richness and pSIE, identified in previous studies
This paper is the fourth in a series and will deal with the geochemical and palynological record of Two Mile Lake. The A. specifically focuses on the representation of Proteaceae species/genera as a contribution to an understanding
of the development of a Proteaceous rich flora in south-western Australia. The results add to the idea that these vegetation taxa were unresponsive to and/or unaffected by climatic changes of the early Holocene.
This paper analyses the spatio-temporal work conducted in and through the Coroner's Inquest in London, with a specific focus on its preventability evidence. This case provides a rich archive in which the potentialities for intervention
Sewage sludge can be used to improve forestry soil properties, because it is rich in phosphorus, nitrogen and organic material and, thus, can enhance the growth of tree seedlings in poor quality soils. The study was performed on a site amended
with industrial sewage sludge and afforested with birch and pine seedlings. To evaluate the growth of tree seedlings, tree dry biomass, height, diameter, root/shoot ratio, specific root length, shoot and root length were calculated. Higher concentrations of heavy
Cities of Germany, could benefit from this growth. The smaller destinations are challenged to cope with their situation by creating specific products and cooperative marketing structures. The staging of the rich cultural heritage in smaller towns could
The distributions of sediment properties including grain size, specific gravity and Cu and Fe concentrations for these phases are presented through a succession of three distinct periods or phases over a five years period: meandering channel phase
, apron phase and rechannelized phase. Copper-rich, coarse grained deposits were found along channel axes and down the apron flanks. The average thickness of and fraction of the sediment column occupied by turbidities was found to increase with distance
The article compares the karst forms of the island of Madre de Dios with the cryo-karst forms observed on the glaciers of north-western Spitsbergen. The specific natural conditions of Madre de Dios are conducive to the fast development and richness
To identify relevant remotely derived environmental indicators specific to biodiversity within the Canadian boreal forest, the AA. assessed indicators of the physical environment such as seasonal snow cover, topography and vegetation production
that the indicators used in the cluster creation provided unique information and explained much of the variance in tree (92.6%), bird (84.07%), butterfly (61.4%) and mammal (22.6%) species richness. Spring snow cover explained the most variance in species richness
Nine samples were collected from a 3 m thick section of the Gratteri Formation cropping out at Casa Asciutto, near Isnello (Madonie Mts.) consisting of yellow silty marls alternating to bioclastic marly and quartzy sandstones, rich in displaced
larger foraminifers,deep water agglutinated foraminifers (DWAF) and bathyal hyaline foraminifers. Upsection the specific diversity tends to decrease, whereas the quartz supply increases and assemblages become exclusively constituted by agglutinated DWAF
on issue framing and boundaries, it investigates what boundaries are drawn, how, why and by whom. The committee is found to play many roles, including analyst, forum for debate and political lever, all of which provide potential for influence on specific
policies, and on the nature and space of political debate. It concludes that the rich and subtle variety of these boundaries, and different work carried out around them, confirms that a simple reading of the EAC’s remit of government scrutiny falls short

Correlating specific conductivity with total hardness in gypsum karst waters
The aim of this paper is to evaluate how adequately simple specific electrical conductivity measurements in the field may be used to estimate amounts of dissolved gypsum and total disolved solids in gypsum karst areas. To illustrate the foreign ion
A high density of settlement (150 inh./km) is a further specific characteristics connected with strongly industrial character of the region. High level of urbanization has accelerated due to demographic transformation and centralization of housing
Critical specific stream power in gravel-bed rivers
Experiments with marked pebbles were carried out on different sized rivers of the Belgian Ardenne (catchment areas varying from less than 1 km2 to 2700 km2). Specific stream power required to cause bedload movement was evaluated and critical values
were obtained. Three types of relationship between critical specific stream power and grain size were established.
