Seabird influence on ecological processes in coastal marine ecosystems: An overlooked role? A critical review
2021
Abstract Seabirds are vital, but overlooked, components of coastal marine ecosystems and may connect the marine and terrestrial environment at a global scale, significantly contributing to inter-habitat connectivity and the provision of multiple ecosystem services. Although the ecological and functional role of birds in terrestrial areas, islands in particular, has been deeply studied since the last century, the same does not hold true for coastal marine areas. Given the importance of coastal areas for seabirds worldwide and, at the same time, the high vulnerability of both, looking into the role of seabirds in influencing the ecosystem functioning in coastal areas is needed nowadays. Here,…
Morphogenetic characteristics of chernozem leached in mining enterprises pollution conditions
2019
The article presents the results of comparative studies on the uncontaminated (virgin) leached chernozem soil in terms of heavy metal contamination due to zinc plant operations. Study object location is given. The territory under the influence of plant emissions is devoid of vegetation. Everywhere on the soil surface there are manifestations of deep erosion processes and continuous erosion of the topsoil. Soil cuts with morphogenetic descriptions, physical, physico-chemical and biological characteristics of the soil were laid at the objects. The soil cover under the influence of pollution has undergone degradation and led to transformational processes of particle size distribution, humus co…
Ecological Functions in the City. Green Infraestructure In Vitoria-Gasteiz
2015
Negli anni recenti, la pianificazione ha cominciato a fare uso di una sorta di razionalità ecologica, nel disegnare le città, che ha portato all’introduzione di misure volte ad accogliere le funzioni naturali nell’ambiente urbano. Da questo punto di vista, Vitoria-Gasteiz nei Paesi Baschi (Spagna) spicca per aver cercato molto a lungo, nella sua storia, di instaurare una relazione equilibrata fra la città e il suo contesto ambientale. Il caso ha ottenuto notorietà internazionale nel 2012, quando la città è stata premiata come “European Green Capital”. Oltre a questa riconosciuta esperienza, a renderla unica è la sua posizione geografica nel Sud dell’Europa, lontano dagli esempi più noti dei…
