In the past few decades, many investigations in the field of plant biology have employed selectively neutral, multilocus, dominant markers such as inter-simple sequence repeat (ISSR), random-amplified polymorphic DNA (RAPD), and amplified fragment length polymorphism (AFLP) to address hypotheses at lower taxonomic levels. More recently, sequence-related amplified polymorphism (SRAP) markers hav...

This paper describes the findings of ethnobotanical research conducted in Tibetan community of agro-pastoralists in Dolpo, northwest Nepal. We assessed vernacular classification and plant nomenclature system with a particular focus on medicinal plants. We aimed to encompass the interpretation of semantic categories, as well as observing directly how people relate to plants in all material and s...

Biological systematics encompasses three distinct activities: taxonomy, classification (which may or may not be a reasonable reflection of phylogeny) and nomenclature (Fig. 1). Although systematists rigorously and distinctly practice these three components, they are often amalgamated under the term “taxonomy.” While the breadth of “taxonomy” is clearly understood among most practitioners, it ca...

The dynamics of nitrate (NO(-) 3), a major nitrogen (N) source for natural plants, has been studied mostly through experimental N addition, enzymatic assay, isotope labeling, and genetic expression. However, artificial N supply may not reasonably reflect the N strategies in natural plants because NO(-) 3 uptake and reduction may vary with external N availability. Due to abrupt application and s...

UNLABELLED PREMISE OF THE STUDY Hyb-Seq, the combination of target enrichment and genome skimming, allows simultaneous data collection for low-copy nuclear genes and high-copy genomic targets for plant systematics and evolution studies. • METHODS AND RESULTS Genome and transcriptome assemblies for milkweed (Asclepias syriaca) were used to design enrichment probes for 3385 exons from 768 ge...

iran contains 33 named endemic fish species, which together with undescribed taxa, approximates one-third of the ichthyofauna. endemism in relatively large species such as fishes, which are better known systematically than other taxa, can often serve to indicate areas in need conservation. an analysis of endemicity is given in terms of systematics, distribution and ecology.
