Staphylinid beetles as bioindicators
The family Staphylinidae is one of the largest beetle families and is distributed worldwide in almost all types of ecosystems. The morpho-ecological characteristics of staphylinid beetle adults and developmental stages are summarized, and features pertaining to their potential use as bioindicators are highlighted. Methods of study and practical examples are given for the application of staphyli...
متن کاملIridoid biosynthesis in staphylinid rove beetles (Coleoptera: Staphylinidae, Philonthinae).
The biosynthesis of chrysomelidial and plagiodial was studied in the rove beetle subtribe Philonthina (Staphylinidae). Glandular homogenates were found to convert synthetic (2E,6E)-[trideuteromethyl-5,5-(2)H(5)]octa-2,6-diene-1,8-diol (10) into nor-chrysomelidial (14) and nor-plagiodial (13). The overall transformation requires; i) oxidation of the substrate at C(1) and C(8), ii) cyclization of...
متن کاملGround beetles in Mediterranean olive agroecosystems: Their significance and functional role as bioindicators (Coleoptera, Carabidae)
The impact of agricultural practices and soil management on the communities of arthropods living in the agricultural landscape is acknowledged as a critical issue by the literature, and it needs to be better investigated to improve the ecological sustainability of agriculture. In the present study, we aimed to study how soil management affect carabid species distribution in one of the most typi...
متن کاملMacrophytes as bioindicators
Submerged macrophytes respond to changes in the nutrient concentrations in their environment. In contrast to diatoms e.g., submerged macrophytes are capable of taking up nutrients from both the sediment pore water and the overlying water. Therefore, macrophytes can provide a more comprehensive assessment of river ecosystems. Two methods using submerged macrophytes to assess and monitor changes ...
متن کاملCyanobacterial community patterns as water quality Bioindicators
The main goal of this study was to examine the use of cyanobacteria for evaluating the quality of running water. Accordingly epilithic cyanobacterial communities were collected in Dez River and Ojeyreb drain in south of Iran. Samples were collected in two seasons: autumn and spring. Effective physical and chemical factors on the structure of cyanobacterial communities and the dispersi...
