Non-native plants that can cause adverse effects are otherwise known as invasive alien plant species which pose a major threat to plant biodiversity conservation and sustainability. This study is dedicated to determine the plant diversity and to assess the vulnerability of Quezon Protected Landscape, Southern Luzon, the Philippines to invasive alien plant species. Data from 90 10x10 m randomly ...

plant tissue culture technique could provide sterile and controllable condition in order to assay direct effect of different compounds on plant growth accurately. in this study, the effects of aqueous extracts prepared from roots and shoots of goosefoot (chenopodium album l.), redroot pigweed (amaranthus retroflexus l.), fennel (foeniculum vulgare), and wormwood (artemisia absinthium l.) were e...

A sample collected from the citrus orchards of the Sari Township, Mazandaran province (N Iran), was determined as Araujia sericifera Brot. (Apocynaceae), according to Markgraf (1972). This species and the genus Araujia, is new to Iran and the region covered by Flora Iranica (Rechinger 1970, 1974).

Anredera cordifolia (Ten.) Steenis, commonly known as the Madeira-vine belongs to the small family Basellaceae is reported as an invasive weed in the gardens and forests of the north of Iran (Fig. 1). Characteristic features of the said plants are as follows: Plant perennial, evergreen, climbing vine or liana that grows from fleshy rhizomes. Stems slender, climbing, up to 3–6 m in height in a s...

Strong competition from invasive plant species often leads to declines in abundances and may, in certain cases, cause localized extinctions of native plant species. Nevertheless, studies have shown that certain populations of native plant species can co-exist with invasive plant species,suggesting the possibility of adaptive evolutionary responses of those populations to the invasive plants. Em...

Differences in plant and herbivore community assemblages between exotic and native ranges may select for different levels of plant traits in invasive and native populations of plant species. Little is currently known of how herbivores may mediate competitive and facilitative interactions between invasive and native populations of plant species and their plant neighbors. Here, we conducted a com...

1. Plants interact with many organisms, such as microbes and herbivores, and these interactions are likely to affect the establishment and spread of plants. In the context of plant invasions, mycorrhizal fungi and constitutive and induced resistance of plants against herbivores have received attention independently of each other. However, plants are frequently involved in complex multi-trophic ...

Although the consequences of the homogenization of Earth’s flora and fauna are not well understood, experts agree that biological invasions pose hazards to rare species. As a result, there is a need for a systematic approach to assess risks from invasive species. The Relative Risk Model can be adapted to assess combinations of rare species, invasive species, and regions. It also can be applied ...
