    Evaluating and measuring biodiversity in a subterranean light-gradient

    ABSTRACT
    The structure and composition of the biodiversity have been analysed in a light gradient of a case-study cave in Northern Italy to evaluate the influence of light in promoting, limiting, or altering it. Minor quantitative variations have been found along the gradient but remarkable qualitative differences have been recorded and discussed on the composition of the biodiversity proceeding from the full light of the entrance toward the darkness of the deep cave. Light intensity proved to be the main limit for many troglobiont an troglophilic species migration from or to the inner part of the cave. The subterranean environment is here discussed as a model for assessing also the epigean biodiversity considering the ecological limits in conservation problems of vulnerable environments.

    Biodiversity indices for the assessment of air, water and soil quality of the “Biodiversity Friend” certification  in temperate areas

    ABSTRACT
    “Biodiversity Friend” is a standard certification developed in 2010 by World Biodiversity Association to evaluate the biodiversity and promote its conservation in agriculture. The procedure to obtain the certification considers the environmental impacts of the agricultural activities on the agrosystem and the biodiversity and suggests operational strategies to improve the environmental quality of the agriculture areas. The evaluation is referred to 12 actions related to low-impact methods of pest and weed control, reconstitution of soil fertility, rational management of water resources, diffusion of hedges, woodlands and nectariferous plants, conservation of agricultural biodiversity, soil, air and freshwater quality through Biodiversity Indices, use of renewable sources for energy supply, lower CO2 production and CO2 storage and other actions that may have beneficial effects on biodiversity.
    The environmental conditions of the agrosystem are evaluated by biomonitoring of air, water and soil. The biodiversity of soil and aquatic macroinvertebrates and the biodiversity of epiphytic lichen communities decrease very quickly when the soil, water and air conditions are altered by different causes such as pollution, synthetic and organic pesticides, bad land use practices, etc. The protocol of the three indices of the standard certification “Biodiversity Friend”: Lichen Biodiversity Index (LBI-bf), Freshwater Biodiversity Index (FBI-bf), and Soil Biodiversity Index (SBI-bf) are here presented in detail.
