Azioni di contenimento dei fenomeni erosivi, di salvaguardia e restauro degli habitat nell’ambito del Progetto LIFE “MACALIFE - Preservation and exte…
2014
In Sicilia, come del resto in gran parte del Mediterraneo, l’impatto millenario delle attività antropiche ha profondamente modificato la struttura e la funzione degli ecosistemi naturali, con evidenti ripercussioni sulla stabilità dei suoli e sull’andamento diffuso dei processi erosivi. L’accresciuta consapevolezza di que-sto rapporto causa-effetto ha posto sempre più in risalto la necessità di mettere in atto adeguati interventi di recupero e di ripristino ambientale, in particolare a favo-re di ecosistemi più esposti e vulnerabili, perlopiù concentrati in corrispondenza delle aree costiere e umide, spesso profondamente trasformati a seguito dell'azione combinata di diversi tipi di disturb…
Functional Redundancy and Complementarities of Seed Dispersal by the Last Neotropical Megafrugivores

No. of bitstreams: 0 Previous issue date: 2013-02-07 Background: Functional redundancy has been debated largely in ecology and conservation, yet we lack detailed empirical studies on the roles of functionally similar species in ecosystem function. Large bodied frugivores may disperse similar plant species and have strong impact on plant recruitment in tropical forests. Th…
Determining the potential impacts of fire and different land uses on splash erosion in the margins of drylands
2021
Abstract This research aimed to estimate the splash erosion and its evolution during the first months in specific land uses after a forest fire. The study area was located in Congosto (North-West Spain), in the margins of Spanish drylands, after a wildfire occurred in May 2012, which burned 15.56 ha of scrubland and Pinus reforestation. Two different burned land uses were selected and compared to control areas: i) burned pine forest; and, scrublands. Rainfall intensity and the number, sizes and speed of raindrops were measured by an optical disdrometer and soil loss by funnels. Moreover, infiltration, soil moisture content, aggregate stability, water repellence, pH and organic matter were a…
FORUM paper: The significance of soils and soil science towards realization of the UN sustainable development goals (SDGs)
2016
Abstract. In this FORUM paper we discuss how soil scientists can help to reach the recently adopted UN Sustainable Development Goals in the most effective manner. Soil science, as a land-related discipline has important links to several of the SDGs which are demonstrated through the functions of soils and the ecosystem services that are linked to those functions. We explore and discuss how soil scientists can rise to the challenge both internally, in terms of our procedures and practices, and externally in terms of our relations with colleague scientists in other disciplines, diverse groups of stakeholders and the policy arena. To meet these goals we recommend the following steps to be take…
A Plant Sociological Procedure for the Ecological Design and Enhancement of Urban Green Infrastructure
2021
AbstractUrban green infrastructure could represent an important mean for environmental mitigation, if designed according to the principles of restoration ecology. Moreover, if suitably executed, managed and sized, they may be assimilated to meta-populations of natural habitats, deserving to be included in the biodiversity monitoring networks. In this chapter, we combined automatised and expert opinion-based procedures in order to select the vascular plant assemblages to populate different microhabitats (differing in terms of light and moisture) co-occurring on an existing green roof in Zurich (Switzerland). Our results lead to identify three main plant species groups, which prove to be the …
Offsetting harmful ecological impacts by restoring conservation areas
2019
Ihmistoiminnasta aiheutuvat ekologisesti haitalliset vaikutukset voidaan kompensoida tuottamalla luonnon kannalta hyötyjä, esimerkiksi ennallistamalla elinympäristöjä tai perustamalla uusia luonnonsuojelualueita. Elinympäristön ennallistaminen mahdollistaa elinympäristön palautumisen kohti luonnontilaa. Tämän tutkimuksen tarkoituksena oli selvittää, voitaisiinko jo aiemmin suojelluilla alueilla tehtävällä ennallistamisella saavuttaa ekologisessa kompensaatiossa tarvittava luontohyöty. Voi ehkä vaikuttaa siltä, että tällä tavoin tuotetut hyödyt eivät ole luonnon kannalta lisäisiä, koska toimenpiteet kohdistuvat alueisiin, jotka ovat jo suojeltu. Suomessa on kuitenkin tällä hetkellä monia suo…
Thresholds in selection of breeding habitat by the Eurasian treecreeper (Certhia familiaris)
2005
Abstract Assessment of habitat thresholds is a topical issue in ecology, both from theoretical and applied perspectives. We examined how forest structure influences selection of breeding habitat in the Eurasian treecreeper (Certhia familiaris). It is an old-growth forest passerine, which can be considered an umbrella species. Habitat selection data, covering five breeding seasons, were collected from a study area across three spatial scales: (a) territory core scale (a radius of 30 m), (b) territory scale (a radius of 200 m) and (c) large scale (a radius of 500 m). Logistic regression analyses revealed that the radii of 30 and 200 m from the nest were the most important spatial scales for t…
Effects of environmental factors on seed germination ofAnthyllis barba-jovisL
2008
Abstract The influence of the main environmental factors on seed germination of Anthyllis barba-jovis L. were analysed. This work is part of a broader investigation aimed at the reintroduction of this species on Mount Conero, Ancona (central Italy), where it is at present extinct. The seeds were collected from the Gargano headland (southern Adriatic coast). Experimental analyses were carried out to determine: (i) dormancy levels of seeds collected in successive years, and also collected from the soil seed bank; (ii) effects of usual pre-treatments for overriding the physical dormancy of the seeds; (iii) optimal temperature range for maximum germination; (iv) effects of fire on seed germinat…
Created substrates do not fully mimic natural substrates in restoration: the occurrence of polypores on spruce logs
2014
Many protected areas have been under intensive forest management prior to protection and thus lack natural ecosystem structures and dynamics. Dead wood is a key structure in forests harboring hundreds of threatened species. We investigated the ecological success of dead wood creation as a boreal forest restoration measure. We analysed whether the polypore communities of chain-saw felled and girdled (subsequently fallen) Norway spruce ( (L.) H. Karst.) logs differ from naturally formed spruce logs of similar decay stage and size. The study was conducted in Leivonmäki National Park in central Finland 8 years after the restoration measures. The average number of polypore species was highest o…
Rapid recovery of invertebrate communities after ecological restoration of boreal mires
2015
Mire degradation due to drainage for forestry results in the loss of mire specialist species. To halt the loss in biodiversity, ecological restoration is needed and already implemented. However, a major challenge in ecological restoration is whether actions taken have the desired outcome. Key abiotic and biotic conditions for the successful restoration of invertebrate communities can be identified by testing the “Field of Dreams” hypothesis, which postulates that if a habitat is successfully restored, species will return. This study was conducted in nine boreal mires located in Eastern Finland, 1–3 years after restoration. Parts of each mire were drained for forestry during the 1960s and 19…
