The study was conducted in a park of Buenos Aires City, where a total of 89 rain pools were sampled weekly for mosquito immature stages over a one-year period. The aim of the present paper was to investigate the seasonal dynamics of three Culex species breeding in temporary rain pools and to analyze the relationships of the presence of these species to pool dimensions, pool age, vegetation, and...

A study was conducted to determine how shade (0%, 40%, 80%) reduces high light intensity and temperature to optimize growth of ranunculus (Ranunculus asiaticus L.) under high altitude tropical conditions. The study was set up in a split plot design, replicated three times and repeated once. Ranunculus tuberous roots were preconditioned at 30C, 20C, 10C or 2C for two weeks and thereafter grown u...

Ranunculus L. is an early diverging clade in the Angiosperm phylogeny. The split between terrestrial and aquatic/semi-aquatic lineages within the genus occurred within 20 Ma (Emadzade and Horandl, 2011), which is much younger than for some well-known aquatic lineages such as Ceratophyllum and Potamogeton. Ranunculus sceleratus Linn. is a semi-aquatic plant commonly found in paddy fields, stream...

Ranunculus arvensis (corn buttercup) is a plant species of the genus Ranunculus that is frequently used in the Far East to treat rheumatic diseases and several dermatological disorders. In Turkey, the plant is seen in the eastern and southeastern Anatolian highlands, which are underdeveloped areas of the country. Herein, we report three patients who used Ranunculus arvensis for the treatment of...

The objective of this paper was to study the in vitro anti-breast cancer activity of polysaccharides from Radix ranunculus ternati. Different concentrations of polysaccharide extracts were selected, and MTT assay and flow cytometry (FCM) were used to investigate their growth-inhibitory and apoptosis-inducing effects on human breast cancer MCF-7 cell lines. Radix ranunculus ternati polysaccharid...

Sequences of the cytochrome c oxidase subunit I (COI) mitochondrial gene from adults of 22 Culex (Culex) species from Argentina and Brazil were employed to assess species identification and to test the usefulness of COI for barcoding using the best close match (BCM) algorithm. A pairwise Kimura two-parameter distance matrix including the mean intra and interspecific distances for 71 COI barcode...

Small-scale heterogeneity of Ranunculus trichophyllus in Lake Tovel (microhabitat, morphology, phenolic compounds and molecular taxonomy) A water buttercup (Ranunculus trichophyllus Chaix) and a stonewort (Chara aspera Detharding ex Willdenow) are forming the actual macrophyte vegetation in Lake Tovel (Prov. Trento, Italy). Both elements and their similar distribution pattern have already been ...
