Mangroves are among the most well described and widely studied wetland communities in the world. The greatest threats to mangrove persistence are deforestation and other anthropogenic disturbances that can compromise habitat stability and resilience to sea-level rise. To persist, mangrove ecosystems must adjust to rising sea level by building vertically or become submerged. Mangroves may direct...

We are limited in our ability to predict climate-change-induced range shifts by our inadequate understanding of how non-climatic factors contribute to determining range limits along putatively climatic gradients. Here, we present a unique combination of observations and experiments demonstrating that seed predation and soil properties strongly limit regeneration beyond the upper elevational ran...

organic matter and its related soil properties are among the most important indicators of soil quality. despite the importance of soil organic carbon, no comprehensive study has been done on organic carbon changes in soils of the isfahan province. the objective of this research was to investigate factors affecting soil organic carbon in soils of this province. a total of 248 surface soil sample...

Physical and chemical soil properties were measured along a mountainous climatological Ž . gradient in the province of Alicante Spain . The objective was to evaluate how the climate affects certain soil properties at different temporal and spatial scales. These properties include infiltration, runoff and sediment concentrations resulting from rainfall simulation experiments performed in winter ...

Site classification in the biogeoclimatic ecosystem classification system is based on three differentiating properties: climatic regimes (expressed by biogeoclimatic subzones or variants), soil moisture regimes (SMRs), and soil nutrient regimes (SNRs). A SNR represents a segment of a regional soil nutrient gradient, i.e., soils which provide similar levels of plant-available nutrients over a lo...

land evaluation is the process of predicting the land use potential on the basis of its attributes. at the present study the qualitative land suitability evaluation was investigated for specific cereal crops including irrigated wheat (triticum aestivum l.), mays (zea mays l.) and cotton (gossypium herbaceum l.), based on fao land evaluation frame works (1976, 1983 and1985), climatic and soil re...

Aim of study: The present study aimed to model soil physical and chemical properties through multiple linear regression tree techniques.
 Area area is located between 41,07 – 41,33 N latitude 41,74 42,27 E longitude in Artvin, which the Colchis part Black Sea Region Turkey.
 Material methods: models were used predict using topographic climatic features as independent variables. Beside...

Long-term measurements of soil nitrogen (N) transformations along an environmental gradient within the Coweeta Hydrologic Laboratory basin in western North Carolina showed a strong seasonal pattern and suggested that vegetation community typethrough its influence on soil properties-was an important regulating factor. Our objective was to determine the relative effects of biotic vs. abiotic fact...

Climatic conditions shift gradually over millennia, altering the rates at which carbon (C) is fixed from the atmosphere and stored in the soil. However, legacy impacts of past climates on current soil C stocks are poorly understood. We used data from more than 5000 terrestrial sites from three global and regional data sets to identify the relative importance of current and past (Last Glacial Ma...

Studying the association between organismal morphology and environmental conditions has been very useful to test hypothesis regarding the influence of climate on shape. It has been long recognized that different environments produce dissimilar stress levels in insects, which can be reflected on the ability of an individual to overcome these pressures and spread further. Agriotes (Coleoptera: El...
