No full textMediterranean temporary wetlands: biodiversity, functioning and conservation
No full textThe aims of this research were to: i) assess plant biodiversity in Sardinian Mediterranean temporary
wetlands (TWs); ii) identify key environmental factors affecting it and possible interactions with
other taxonomic groups, and iii) define conservation issues.
Plant biodiversity was evaluated at different spatial scale. The application of a fine-scale zonation
sampling approach allowed identifying different assemblages “within TW”, with different floristic,
structural, and sintaxonomical features at each site in the same relative position. Three belts were
recognized: central, intermediate and outer characterised by different water depth and flooding
period. Comparisons at scale of the entire temporary TW pointed out differences due to substratum,
elevation and size. At temporal scale differences between assemblages were significant only in the
same environmental conditions (e.g. TWs located at the same site). While vegetation pattern was
mainly driven by “within TW” effect, investigation on soil pattern pointed out that it is mainly due
to “a site effect”. Significant positive relationships were found between plant and crustacean
assemblages, not only in terms of community structure but also at composition level. Conservation
relevance was related to the presence of habitats of Community interest and listed species.
Intraspecific variability and conservation status were assessed to some species strongly dependent
to this habitat type (e.g. Isoetes histrix)

Full text linkThe research was undertaken with the aims to improve the knowledge of small scale
distribution of plant communities in Mediterranean temporary habitats and to evaluate
their diversity and conservation relevance in order to provide a sound basis for the
prioritization of conservation efforts according to the Habitats Directive
Vegetation series: a tool for the assessment of grassland ecosystem services in Mediterranean large-scale grazing systems
No full text"Large-scale grazing systems (LSGS) are areas in which land-based livestock farming is the dominant productive activity and where grasslands, mainly of secondary origin, represent the main resource. To assess and make comparable the ecosystem services (ESS) of secondary grasslands, a clear space-time reference is needed. In this context, the concept of vegetation series may support the modeling of the dynamic succession trajectories of vegetation in relation to grazing and land use intensity and the identification of ESS benchmarks (e.g. the potential vegetation). While relating ESS to different dynamical stages within a vegetation series it will be possible to identify which land use types should be more useful to improve the effectiveness of one or more ESS. The paper illustrates 3 case studies in which the vegetation series model supported the assessment of grassland ESS in Mediterranean LSGS..
