Land use change threatens global biodiversity and compromises ecosystem functions, including pollination and food production. Reduced taxonomic α‐diversity is often reported under land use change, yet the impacts could be different at larger spatial scales (i.e., γ‐diversity), either due to reduced β‐diversity amplifying diversity loss or increased β‐diversity dampening diversity loss. Additionally, studies often focus on taxo...
Investigating the genetic structure of trout from the Garden of Ninfa (central Italy): Suggestions for conservation and managementNARA Subscribed
Mediterranean populations of brown trout ( Salmo trutta L. complex) have lost a large part of their genetic distinctiveness, mostly due to massive restocking, and the waters of the Gardens of Ninfa (province of Latina, central Italy, Site of Community Importance since 2013) are regarded as one of a few potential reservoirs of autochthonous trout lineages in the Tyrrhenian drainage of the Italian peninsula. In this study, nucle...
Agricultural intensification is a leading cause of global biodiversity loss, which can reduce the provisioning of ecosystem services in managed ecosystems. Organic farming and plant diversification are farm management schemes that may mitigate potential ecological harm by increasing species richness and boosting related ecosystem services to agroecosystems. What remains unclear is the extent to which farm management schemes af...
A global quantitative synthesis of local and landscape effects on wild bee pollinators in agroecosystemsNARA Subscribed
Bees provide essential pollination services that are potentially affected both by local farm management and the surrounding landscape. To better understand these different factors, we modelled the relative effects of landscape composition (nesting and floral resources within foraging distances), landscape configuration (patch shape, interpatch connectivity and habitat aggregation) and farm management (organic vs. conventional...
Genetic differentiation and hybridization in two naturally occurring sympatric trout Salmo spp. forms from a small karstic lakeNARA Subscribed
In this study, multiple molecular markers [genotyping of 12 nuclear microsatellite loci and the protein‐coding gene ldh‐c1 * plus sequencing of the mitochondrial DNA ( mtDNA ) control region] were employed to investigate the genetic structure of the two trout forms, Salmo cettii and Salmo fibreni , inhabiting Lake Posta Fibreno, central Italy. The two forms were found to share a unique mtDNA haplotype, belonging to a widesprea...
Genetic data are currently providing a large amount of new information on past distribution of species and are contributing to a new vision of Pleistocene ice ages. Nonetheless, an increasing number of studies on the ‘time dependency’ of mutation rates suggest that date assessments for evolutionary events of the Pleistocene might be overestimated. We analysed mitochondrial (mt) DNA (COI) sequence variation in 225 Parnassius mn...
