Accumulations of heavy metals in urban soils are highly spatial heterogeneity and affected by multiple factors including soil properties, land use and pattern, population and climatic conditions.
However, since only one gene displayed this pattern, population expansion is thus unlikely Synonymous (πs) and nonsynonymous (πa) nucleotide diversity was calculated for each gene within each group (Table 1) revealing values below one for PGRP-S2 and PGRP-S3, suggesting purifying selection (Table 1).
In most regions, monsoon patterns, population and consumption pressures and dependence on groundwater pumping will remain the dominant source of water-related risks, the report concludes.
Butz identified changes in rainfall patterns, population growth and fire suppression policies as the drivers of the change in the fire regime.
Six Malayan sun bears were captured and radio-collared from June 1999 to December 2001 in Ulu Segama Forest Reserve, Sabah, Malaysia Borneo to study home-range characteristics, movement patterns, activity patterns, population density, and bedding sites.
We analyze historical, qualitative data to identify five major socio-ecological drivers critical to understanding the urbanization processes and fragmentation patterns: population dynamics, water provisioning, technology and transportation, institutional factors, and topography.
Genetic analysis of our ancestors may thereby contribute to our understanding of migration patterns, population affinities, replacements, tribal patterns and family structure.
In heterogeneous environments spatially varying habitat quality leads to habitat-specific demography affecting the structure and dynamics of populations by determining habitat-specific settlement patterns, population regulation, and population persistence [1] [5].
By contrast, geographically patterned population substructure appears much weaker within the S-form.
Hagen et al. (2008) Anisotropic patterned population synchrony in climatic gradients indicates nonlinear climatic forcing.
These are all the regions with a well-established conservation tradition, but they differ considerably in terms of their land use patterns, population and labour market.
