Descrizione delle specie italiane apparteenti al genere Moehringia. Chiave dicotomica per il riconoscimento delle specie.

Previous studies have indicated that several plant species had shown remarkable resistance to Pleistocene climate changes and survived the Last Glacial Maximum in scattered ice-free refugia within the European Alps and peripheral areas nearby. The 'Expansion–Contraction' model has been proposed to describe the responses of organisms to...

Climate change is one of the greatest threats to plant endemisms, particularly in mountain ecosystems that often show a high rate of endemism. Studies suggest that current centers of endemism are typically located in areas where the rugged mountainous topography buffered the effect of past climate changes and will probably buffer also the...

Delimiting taxon boundaries is crucial for any evolutionary research and conservation regulation. In order to avoid mistaken description of species, the approach of integrative taxonomy recommends considering multidisciplinary lines of evidence, including ecology. Unfortunately, ecological data are often difficult to quantify objectively....

Scheda di monitoraggio della specie endemica Campanula sabatia all'interno del manuale 140 dell'ISPRA - Ministero dell'Ambiente e della Tutela del Territorio e del Mare

Climate change is one of the greatest threats to biodiversity, particularly in mountain ecosystems, which often show high endemism rate. Studies on past climate changes suggested that current centers of endemism are placed where climatic fluctuations were less pronounced (because of mountainous topography) and that these areas will be less...

For over a century, species delimitation was a critical task for biologists, concerning both species concept and operational methods necessary for the individuation of taxa boundaries. According to the recent approach of integrative taxonomy, species have to be considered as hypotheses that should be tested with different methods. Ecological...

A morphological comparison between two similar species growing in the SW Alps. New data on the distribution of the two species in the Ligurian Alps

To understand the relations between environment and phenotypic plasticity is important to forecast any possible adaptation of plants to climate change. We tested for any difference between central and marginal (Mediterranean and Alpine). Study was performed on 20 populations chosen on the basis of their distance from niche optimum.In...

Per monitorare la flora di spiaggia ligure e valutarne i cambiamenti in relazione al cambiamento climatico e soprattutto al cambiamento dell'uso del suolo sono stati effettuati dei campionamenti in 16 località costiere della Liguria [da Capo Noli (SV) a Sestri Levante (GE)] eseguiti da Marzo ad Aprile 2021. I campioni sono stati identificati in...
