Understanding how plant trait-species abundance relationships change with a range of single and multivariate environmental properties is crucial for explaining species abundance and rarity. In this study, the abundance of 94 woody plant species was examined and related to 15 plant leaf and wood traits at both local and landscape scales involving 31 plots in subtropical forests in eastern China....

continuous availability of soil water is an important factor for plant growth. both lack of adequate access to water in soils, or adequate oxygen in saturated soils, may reduce or even stop plant growth. to study the behavior of pistachio seedling at various moisture levels and to determine non-limiting water range for its growth, a greenhouse experiment with a completely randomized design was ...

evaluation of range conditions and plant diversity circumstances can help to rangeland managers who establish their managerial approaches on the basis of ecological capabilities of rangeland ecosystems. hence, surveying of rangelands was done in four sites of northern alborz mt. including western alborz (masooleh site), west to middle alborz (javaherdeh site), central area (polour site), and ea...

Many studies have paid particular attention to the role of either secondary plant compounds or amino acids as determinants of host-plant range in phytophagous insects. Here we examine the relative importance of both of these classes of compound in host acceptance by generalist and specialist morphs of the black bean aphid, Aphis fabae, that are morphologically similar and genetically identical....
