Biological diversity in forest ecosystems results from evolutionary processes driven by ecological imperatives linked to pathogens, symbionts, fire, climate, and competition or impacts from other agents of disturbance. To understand the behavior of microorganisms and microbial pathogens, it is necessary to have a comprehensive appreciation for the diversity of their functional attributes in the...

Members of the entomophagous fungi are considered very crucial in the fungal domain relative to their natural phenomenon and economic perspectives; however, inadequate knowledge of their mechanisms of interaction keeps them lagging behind in parallel studies of fungi associated with agro-ecology, forest pathology and medical biology. Ophiocordyceps sinensis (syn. Cordyceps sinensis), an intrica...

Whether viewed or heard, an object in action can be segmented as a distinct salient event based on a number of different sensory cues. In the visual system, several low-level attributes of an image are processed along parallel hierarchies, involving intermediate stages wherein gross-level object form and/or motion features are extracted prior to stages that show greater specificity for differen...

BACKGROUND & OBJECTIVES Meccus pallidipennis is one of the most epidemiologically important vectors of Trypanosoma cruzi to reservoir hosts in nine states of Mexico. Triatomines occurring in distinct locations normally adapt to local conditions. The aim of this study was to examine the biological attributes of three populations of M. pallidipennis from areas with different environmental charact...

Objectives The objective of this research is to characterize biological, physical and chemical soil quality parameters and monitor their changes over time in minimum tillage and no-till seeding systems as affected by tillage, crop species and management systems to identify soil quality attributes that can be used in the development of best management practices for conserving soil quality and en...

soil particle-size distribution (psd) is one of the most important physical attributes due to its great influence on soil physical, chemical, and biological properties. water infiltration rate, land-use change, soil erosion, and biological soil crusts (bscs) may influence psd in a soil. the multifractal measures were useful tools in characterization of psd in soils. the objective of the current...

The manner by which the organization and behaviors of cells arise from the activities of their constituent molecules remains poorly understood. Approaches from the physical sciences for studying collective properties may help with this difficult problem, but they must be adapted to account for the specific attributes of biological molecules.
