Eryngium foetidum L. is an important plant cultivated as leafy vegetable and for its essential oil, which is of high economical value in international market. Multiple shoots (17.8) were obtained through direct regeneration from leaf excised from field grown plants of E. foetidum and cultured on Linsmaier and Skoog’s Basal Medium (LSBM) fortified with BAP (1.5 mgl) and PVP (250 mgl). After subc...

The host-plant fidelity, seasonality, and population dynamics of 3 species of Culex (Culex) were examined from monthly samples of mosquito immatures extracted from the leaf axils of Eryngium pandanifolium and Eryngium cabrerae growing sympatrically in the Punta Lara region of Buenos Aires Province, Argentina. Culex hepperi was collected only from E. pandanifolium, and abundance peaks of its lar...

A list of the most common plants that form phytotelmata and their associated coleopterans (aquatic, semi-aquatic and terrestrial) from the northeastern subtropical and temperate area of Argentina, South America with biological and behavioral observations is presented in this study. Species of Poaceae (n = 3), Bromeliaceae (5), Apiaceae (6), Araceae (2), Urticaceae (1), Marantaceae (1), Arecacea...

Apterous and alate viviparous females of Protaphis kvavadzei sp. n. on Eryngium campestre (Apiaceae) and Aphis matricariae sp. n. on Matricaria sp. (Asteraceae) from Turkey are described. The new species are differentiated from other aphids colonising these host plants and from species with similar morphology.

Species interactions are well known to affect species diversity in communities, but the effects of parasites have been less studied. Previous studies on parasitic plants have found both positive and negative effects on plant community diversity. Cuscuta howelliana is an abundant endemic parasitic plant that inhabits California vernal pools. We tested the hypothesis that C. howelliana acts as a ...

Eryngium maritimum is a coastal plant of the Apiaceae family. This species is threatened in several countries where it reaches the northern limits of its distribution area. Existing populations in the Baltic Region and Scandinavia are potentially affected by the low efficiency of its generative reproduction. We studied physiological aspects of its germination and dormancy breaking requirements ...
