The phosphate fertility of soils and the risk of contaminating of the deep ground water tables by modern agricultural practices, enable the authors to underline the importance attached to the knowledge of different edaphic parameters in solving
Edaphic limitation of a brazilian rainforest palm : the role of energy allocation and competition for sunlight
In the Atlantic Coastal Forest Biome of eastern Bahia, the piassava palm (Attalea funifera) inhabits coastal podzolic soils but not nearby latosols. This paper examines the role of changing edaphic conditions and access to sunlight
Periglacial phenomena and their significance as climatic and edaphic indicators in Polar research.
It can be shown that each type of periglacial phenomenon is dependent on specific climatic and edaphic conditions. Data on these conditions are compiled in several tables. On the other hand, because of this dependence on specific environmental
This paper gives a systematic survey of the periglacial landforms of Iceland. The presentation is centered on the question of the significance of distinct periglacial features on certain climatic and edaphic environmental conditions
The AA. performed a content analysis on previous research that examined alpine treeline in national parks and classified each treeline study as anthropogenic, orographic/edaphic, or climatic according to the primary factor attributed to treeline
control. Results indicated that the 3 types of treeline are not uniformly studied. Climatic treeline is most commonly studied whereas anthropogenic and orographic/edaphic studies are often lacking. Furthermore, several western national parks are entirely
This paper examines the heterogeneity of the edaphic environment at alpine treeline to determine if differences exist in the nutrient status (carbon, nitrogen, phosphorus, and potassium) of soils underlying tundra and arboreal vegetation. Data
nutrients occur ar the more xeric treeline sites. Heterogeneity of the edaphic environment has the potential to structure treeline response to climate change.
Scale-dependent correspondence of floristic and edaphic gradients across salt marsh creeks
This research addresses the issue of scale-dependence, focusing on spatial correspondence of floristic and edaphic gradients across salt marsh creeks at Skallingen, Denmark. The AA. employed a hierarchical approach, which compared vegetation
Most pediments in the Gongola Basin are developed on bedrock. Field observations indicate erosion processes which have been affected by climatical dry conditions of the Late Pleistocene. Since that time, edaphical dryness on the pediment surfaces
Two field sites in the Judean Desert, in close proximity to each other, were compared with regard to plant species richness, production, and population dynamics. Although having very similar climatic conditions, the two types differed in edaphic
A comparison is made between winter snow cover, Continentality Index values, freezing and thawing indices, and the apparent edaphic-ecological wetness and dryness of the sites as judged by distribution of differing types of alpine vegetation, soils
This paper presents an agroclimatic rating scheme that is based on the frequency of extreme weather conditions. The rating scheme is designed so that it easily can be decomposed into its component parts and integrated with edaphic and topographic
been measured or estimated, all of the plants have been identified and their coverage estimated. In this way, the knowledge of their ecology was improved and their coverage estimated. Experiments which are based upon three principles edaphic zonation
The main objective of this research is to determine the influence of edaphic parameters and mean annual precipitation on the soil organic carbon levels in the surficial horizons of the semiarid-arid transition of Argentina, in order to establish
of associations. The differentiation of vegetation associated with the macroforms manifests in the geographical units (i. e. races, vicariant endemic associations) and related with the mesoforms as the associations and subassociations of different edaphic
The objective of this study is to determine if a main gradient is detectable in the woody plant composition in this hyper- to semi-arid environment; and to which extent climatic and edaphic variables account for it. A cluster analysis detects two
plant functional groups: a tropical desert formation and a shrub and dry forest formation. Variation partitioning reveals edaphic variables to be more important in structuring vegetation than mean annual rainfall. Extending irrigation in parts
Influence of topographic and edaphic factors on vulnerability to soil degradation due to cattle grazing in humid tropical mountains in northern Honduras
under the present Danish edaphic and climatic conditions. pH data of surface soil showed a decrease of 0.7-0.9 units within the last 50 years, which suggests that the present soil development might change rapidly due to soil acidification.
