Soil microorganisms play an important role in urban green spaces by providing ecological functions. However, information on the structure and assembly of microbial communities public risk pathogenic bacteria remains elusive. Here, we conducted a field survey soil organisms different vegetation cover types (e.g., grasslands, shrublands, woodlands) based 16 S rRNA gene amplicon sequencing. We fou...

Noise pollution of roads can propagate within a broader extent than the road only. This spatial space is called "road ecological effect zone" which is known as the natural areas exposed by 40 dB or greater noise level in both sides of the road. In this study, using Calculation of Road Traffic Noise (CRTN) model, the propagation range of noise from Lorestan road network was simulated. Then, the ...

We present a review on the state-of-the-art of fruit prodution in Western Iberia woodlands («dehesas»), and particularly in Q. ilex (holm oak) «dehesas». This threatened ecosystem is of very high ecological and economical importance. Quercus sp. fruits (acorns) are essential for wildlife, and for pig fattening in «dehesas». In the first part of this review we briefly describe the phenology of t...

There are only five mediterranean-climate regions (MCRs) on Earth – the Mediterranean Basin, most of California, central Chile, southern South Africa, and south-central and south-western Australia. They all have cool, or cold, and relatively wet winters alternating with long, hot, and dry summers. Spring and autumn seasons are ephemeral in comparison, and highly variable. During much of the yea...

Tall tuart (Eucalyptus gomphocephala) trees are a defining element of the landscape of Perth and the coastal plain to the north and south. However, with the health of some tuart stands deteriorating, most notably at Yalgorup south of Perth, concerns are heightening that the already fragmented tuart ecosystem will continue to contract, leaving a cultural and ecological scar in the landscape. Lik...

We sampled characteristics of vegetation and estimated abundances of bird species on 23 plots representing a continuum of tree densities of the blue oak phase of the Coast Range foothill woodland near Hopland, California. Fifty-one bird species were found breeding. Cavity-nesters dominated the bird community in number of species and individuals. Cavitynesters used a variety of tree species for ...

Abandoned management has caused many sites with free-standing, large oaks (Quercus robur) to become more shaded. This study shows how forest regrowth affects beetle species associated with old oaks in south-eastern Sweden. Beetles were trapped by pitfall traps placed in hollows and window traps placed near hollows in oak trunks in pasture woodlands. We assessed the influence of forest regrowth,...

Creating native woodland is a policy goal globally, and one strategy to maximize creation benefits in limited space target efforts extend existing woodlands. There evidence support spatially targeting habitat for biodiversity, however, there little of how this affects habitat's structural development. Here, space-for-time study using light detection ranging (LiDAR) data assesses the structure r...

There is a lack of precise guidelines concerning the survey effort required for advanced bat surveys in temperate European woodlands, resulting standardisation methods. In this study we assess catch data from 56 trapping at 11 UK woodland sites order to provide recommendations mist net gain meaningful assemblage woodlands. Species accumulation curves were produced and used develop two novel val...
