We tested the recolonization of the phytobenthic community in the tailwaters of Glen Canyon Dam following longand short-term experimentally induced desiccation. The response of Cladophora glomerata, Oscillatoria spp., miscellaneous phytobenthos species and periphyton was studied over 18 weeks using three treatments: (1) undisturbed control cobbles from the submerged zone; (2) cobbles desiccated...

Amaç: Bu çalışmada Rubiaceae familyasına ait endemik Asperula lilaciflora subsp. phrygia’nın farmasötik botanik açıdan araştırılması amaçlanmıştır. Gereç ve Yöntem: Eskişehir-İnönü’den toplanan bitki morfolojik araştırmalarda değerlendirilirken, tüy polen morfolojisi SEM’de incelenmiştir. Anatomik çalışmalarda %70’lik alkole alınan örneklerin manuel kesitlerinde, yapıları aydınlatılmış fotoğraf...

The present study primarily aims to identify the relative density and the fatty acids (methyl esters) content present in the standardized ethanol extract of leaves of M. glomerata (EPMG). Meanwhile, in a second moment, this study evaluated the effects of the EPMG on the levels of amino acids in the hippocampus, and the mechanism of sedative and anxiolytic action. Adult mice were treated with do...

Neste estudo investigou-se o papel de uma doença fúngica (Puccinia mikaniae H. S. Jacks. & Holw) na produção e acumulação cumarina em Mikania glomerata Spreng. (Asteraceae). Conhecida como “guaco”, esta planta é nativa do Brasil suas folhas são utilizadas no tratamento desordens respiratórias, sendo a seu marcador químico. Avaliou-se teor deste amostras obtidas diferentes M. saudáveis ou es...

The article describes a new hybrid namely Gypsophila × moldavica Pînzaru (G. glomerata G. collina), formed under ex situ conditions, in the author's private garden. Arguments have been brought to support claim of recognizing species Adams and it is considered appropriate synonymize pallasii Ikonn.

BACKGROUND AND AIMS Current agricultural practices are based on growing monocultures or binary mixtures over large areas, with a resultant impoverishing effect on biodiversity at several trophic levels. The effects of increasing the biodiversity of a sward mixture on dry matter yield and unsown species invasion were studied. METHODS A field experiment involving four grassland species [two gra...
