Abstract Background Hedera helix L. is an invasive weed species introduced in several regions of the world, so it relevant to study its effects on plant community and changes occurring after eradication. We established invaded (with/without removal H. ) non-invaded understory) plots compare some attributes oak forest Mexico City monitored them every 2 months for 1 year, taking soil samples edap...

during visit beech forests of mazandaran province in may and june of 2010-2011, some infected twigs of fagus sylvatica with signs of fungal infection were collected. laboratory analysis revealed acervular fruiting bodies on infected twigs. acervulus up to 500 μm in diameter and forming a black spot on main and secondary twigs. conidia erumpent, form black masses over the acervulus. conidia are ...

Abstract To ensure sustainable forest management, the assessment and monitoring of soil compaction rutting are essential. Here, we used airborne light detection ranging‐derived digital terrain model (LiDAR‐derived DTM), available for Compiègne in northern France, to compute a spatial index rutting. Following an environmental systematic sampling design, selected 45 plots representative stand con...

Segundo a RDC N° 26/2014, fitoterápicos são produto obtido de matéria-prima ativa vegetal, com finalidade profilática, curativa ou paliativa. A necessidade do controle microbiológico desses produtos é importante, devido, principalmente, à segurança, eficácia e aceitabilidade produtos. O trabalho teve como objetivo avaliar o xaropes base da planta Hedera helix L. Foram analisadas duas marcas fit...
