Structural features of porous materials such as soil define the majority of its physical properties, including water infiltration and redistribution, multi-phase flow (e.g. simultaneous water/air flow, or gas exchange between biologically active soil root zone and atmosphere) and solute transport. To characterize soil microstructure, conventional soil science uses such metrics as pore size and ...

This study aims to examine pollen morphologically via studies of 16 plant taxa from Turkish flora. The structures the examined, and their microscopic relevance, was discussed studied with help visualization using scanning transmission microscopies. Pollen grains were first acetolyzed, then quantitative qualitative features used evaluate species. prolate, spherical, elliptic, tricolporate, 3-col...

The grass family (Poaceae) has been recognized as a unique lineage for more than 200 years, based initially on characters of inflorescence and spikelet morphology and corroborated by anatomical and other features in the latter half of the twentieth century. There have been a number of attempts to derive a phylogeny of sections of the family from structural (morphological and anatomical) charact...

Basin hydrologic response is a function of soil moisture distributional featuresAn information-based dimensionless index of hydrologic complexity is appliedThe complexity index characterizes soil moisture distributional features.

soil compaction has become a widespread problem in the world and it is considered as one of the main factors affecting land degradation in arid and semi-arid agricultural land. the aim of this study was to investigate the effects of soil compaction on soil carbon and nitrogen sequestration, physical (aggregate stability, saturated soil moisture content, bulk density, and porosity) and chemical ...

Soil moisture is a key state variable of the hydrologic cycle. It plays a significant role in many hydrological, meteorological and other natural processes in the land-atmosphere continuum. In the past two decades we have conducted several field campaigns to better understand the underlying processes controlling the spatio-temporal variations of soil moisture using multiple ground, air, and spa...

The genus Anthoxanthum s.l. (including Hierochloë) (Poaceae, Pooideae, Aveneae) comprises 35– 50 species and has a cosmopolitan distribution. Anthoxanthum alpinum was described as a diploid perennial that is distributed in northern Eurasia and in the high mountains of central and eastern Europe. Difficulties in finding reliable morphological differences between this taxon and the widespread tet...

Florida Everglades restoration plans are aimed at maintaining and restoring characteristic landscape features such as soil, vegetation, and hydrologic patterns. This study presents the results from an exhaustive spatial sampling of key soil properties in Water Conservation Area 1 (WCA 1), which is part of the northern Everglades. Three soil strata were sampled: floc, upper 0- to 10-cm soil laye...
