Sono riportati i primi dati sull'osservazione dell'eventuale presenza di Nitidulidi su piante di Acanthoprasium frutescens in tutto il suo areale di distribuzione. Si suppone l'eventuale presenza di coleotteri predatori dei fiori che prò non sono mai stati ritrovati ne sottoforma di larve ne di adulti. Una analisi morfologica con latre...

In questo lavoro si è fatta verifica del reale areale di distibuzione della specie e viene effettuata una accurata descrizione dlle popolazioni certe della specie. Un confronto anatomico-morfologico mette in evidenza come la specie possa formare potenziali ibridi con una gogenerica simpatrica.

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....

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...

Sono qui riportati i primi risultati di indagini vegetazionali sulla distribuzione dell'habitat 3170 "stagni temporanei mediterranei" secondo la Direttiva Europea Habitat in tutto il terrritorio ligure. Si evince che la distribuzione, influenzata molto dalle variazioni climatiche e dalle dinamiche in seno agli habitat fluviali, è estremamente...

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

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...

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...

dispetto delle piccole dimensioni, le sorgenti sono habitat di grande valore ecologico che, specialmente negli ambienti aridi, influenzano significativamente l'ecosistema circostante (Odum 1971, Cartwright et al. 2020). Le sorgenti calcaree pietrificanti, fitosociologicamente riferibili all'alleanza Cratoneurion commutati Kotch. 1928, sono...

Censimento dei muschi presnti nelle faggete delle ZSC Direttiva Habitat gestite dal Parco dell'Aveto in Liguria

Endemic species are not uniformly distributed across the world but some areas are richer than others. In general, it is widely recognized that past climate changes strongly affected endemic richness and distribution. Endemic species shifted little their distributional range over time, accumulating in the so-called areas of persistence because...

Analysis on the efficience of the protected areas belonginig to the European Natura2000 network for the conservation of endemic plants in a changing world climate

Climate change seriously threatens biodiversity, particularly in mountain ecosystems. However, studies on climate change effects rarely consider endemic species and their niche properties. Using species distribution models, we assessed the impact of climate change on the endemic flora of the richest centre of endemism in the Alps: the...
