Preschool children's taxonomic knowledge of animal species

A TAXONOMIC STUDY ON ALTERNARIA SPECIES IN IRAN (2)

In the continuation of studies on Alternaria species, some 500 isolates were obtained from seeds, soil and plant parts from various localities of Iran. Prior to morphological examination, pure cultures were obtained by single conidium and single chain methods. Descriptions for each taxon are based on cultures developed on potato carrot agar. Inoculated plates were incubated at 23-25°C under a c...

Animal Evolution: Trichoplax, Trees, and Taxonomic Turmoil

The genome sequence of Trichoplax adhaerens, the founding member of the enigmatic animal phylum Placozoa, has revealed that a surprising level of genetic complexity underlies its extremely simple body plan, indicating either that placozoans are secondarily simple or that there is an undiscovered morphologically complex life stage.

NUMERICAL TAXONOMIC STUDY OF THE IRANIAN SPECIES OF ALYSSUM L. BASED ON MORPHOLOGICAL CHARACTERS

The genus Alyssum L. belongs to the subtribe Alyssinae, tribe Alysseae and family Cruciferae (Brassicaceae). This genus is one of the largest genera of the family of Cruciferae in Iran, and seems to be the most problematic genus in which the boundary of certain species is not completely clear due to the polymorphism of morphological characters. The main objective of this research is to stud...

the relationship between bruxism and malocclusin among preschool childrens in isfahan

background and aims. bruxism is defined as a habitual nonfunctional forceful contact between occlusal tooth surfaces. in younger children bruxism may be a consequence of the masticatory neuromuscular system immaturity. the aim of this study was to assess the prevalence of bruxism and investigate the relationship between occlusal factors and bruxism among preschool children. materials and method...
