Data-intensive technologies such as precision agriculture require new approaches for acquisition of soil data on landscapes. We compared the ability of near infrared (NIR; 400–2500 nm) and mid infrared (MIR; 2,500– 25,000 nm) spectroscopy for field-scale acquisition of soil fertility parameters. Samples were obtained in a grid pattern (25 m spacing) from the surface (0–10 cm) and sub-surface (1...
Urbanization contributes to the loss of the world's biodiversity and the homogenization of its biota. However, comparative studies of urban biodiversity leading to robust generalities of the status and drivers of biodiversity in cities at the global scale are lacking. Here, we compiled the largest global dataset to date of two diverse taxa in cities: birds (54 cities) and plants (110 cities). W...
Private gardens provide habitat and resources for many birds living in human-dominated landscapes. While wild bird feeding is recognised as one of the most popular forms of human-wildlife interaction, almost nothing is known about the use of bird baths. This citizen science initiative explores avian assemblages at bird baths in private gardens in south-eastern Australia and how this differs wit...
variety of iran’s ecological structures has created many cultural landscapes. cultural landscapes, illustrate a combination of man’s persistent life and the art of land modification by means of natural environment and in the form of human settlements in past ages. currently, the human society’s development beside the scientific growth, man’s increasing use of natural resources and negative cons...
iran has mountainous landscapes and half of its surface is occupied by highlands. moreover, iran is an arid country and deserts are located at lower altitudes. most metropolitan areas are positioned in mid-altitudes between mountain and desert. cities grow upwardly toward the highlands under pressures of urbanization and desertification. foothill ecotones are a zone between upland mountains and...
In agroecosystems, local and landscape features, as well as natural enemy abundance and richness, are significant predictors of predation services that may result in biological control of pests. Despite the increasing importance of urban gardening for provisioning of food to urban populations, most urban gardeners suffer from high pest problems, and have little knowledge about how to manage the...
The soil pollution especially in urban soils is projected to increase drastically and its effects on chemical cycles are yet to be known. Approaches to measure air and water quality are well established, but urban soil quality assessment has received little attention. Soil quality assessment can help as a way to better understand the pollution increase outcomes in urban environments and to esta...
