Abstract The segetal flora of winter crops includes mostly native or archaeophyte annual species that are often strong specialists of their habitats. Threatened by the intensification of agriculture, segetal flora is particularly valuable from a perspective of biodiversity conservation and evolution. Moreover, it contributes to maintain biodiversit...

The interest in knowledge of the weed communities of arable land is growing worldwide. Italy is one of the countries in Europe that is the most biodiverse, geographically and environmentally heterogeneous, and rich in arable weed species. Thus, in this study, the geo-environmental factors influencing the floristic composition, the species richness,...

Detecting patterns of species co-occurrence is among the main tasks of plant community ecology. Arable plant communities are important elements of agroecosystems, because they support plant and animal biodiversity and provide ecosystem services. These plant communities are shaped by both agricultural and environmental drivers. The pressure of inten...

The weed vegetation of the bean “Fagiolo Cannellino di Atina” ( Phaseolus vulgaris L.) and the red pepper “Peperone di Pontecorvo” ( Capsicum annuum L.) PDO (Protected Designation of Origin) crops was surveyed by means of 16 relevés, sampled in four farms of southern Latium during July 2019. The relevés were subjected to multivariate analysis, whic...

The database consists of over 30,000 records, derived from different sources. We provide information and analyses on life forms, cho...

The concept of “weed” is very subjective, as any plant that interferes with human activities can be considered a weed. Almost exclusively annual, weeds of arable land are called “agrestals” or “segetals” and were negatively affected, in Europe, by the intensification of agriculture. In recent years, many studies highlighted the ecological and agron...

In July 2019, we surveyed the weed flora of "Peperone di Pontecorvo" (red pepper) and "Fagiolo cannellino di Atina" (bean) P.D.O. crops (Latium region, central Italy). We recorded 52 species belonging to 43 genera and 21 families. The most frequent taxa were Amaranthus retroflexus, Convolvulus arvensis, Portulaca oleracea, Sorghum halepense, Cyperu...

The Herbarium Museum of Sapienza University of Rome (RO) hosts over one million specimens, in several historical and contemporary collections. It is divided into six main Herbaria (Erbario Romano, E. Generale, E. Cesati, E. Montelucci, E. Anzalone, E. Bazzichelli), and several minor collections (1). The computerized cataloging of RO Herbarium colle...

Changes in agricultural practices represent one of the main causes of shift in species composition of arable plant communities. In particular, the intensification of agriculture going on worldwide since several decades led to heavy transformations of arable plant diversity. Basing on a study conducted in 1964 in Latium (central Italy), we re-survey...

The anthropogenic therophitic grasslands dominated by tall Poaceae of Italy were recently included in the alliance Securigero securidacae- Dasypyrion villosi (Chenopodietea). Similar vegetation types from Sicily, Sardinia, Albania, and Greece were hypothesized to pertain to this syntaxon. In this work, we performed multivariate analyses on 493 phyt...

Aims: We present the results of a phytosociological investigation of segetal plant communities colonizing winter arable fields, olive groves, and vineyards in selected traditional agricultural areas of central Italy. Some of these communities have great environmental and cultural value and are threatened by changes in agriculture. Given the lack of...

During the second half of the twentieth century, agricultural practices in Italy underwent a fast transition from extensive and traditional to intensive and specialized. Weed assemblages colonizing cultivated fields were thus subjected to major shifts, mainly driven by the increased use of herbicides and chemical fertilizers. Moved by the early int...

Seeds and fruits collections are very important from a systematic point of view and represent useful references in several disciplines and research elds. The Herbarium of Sapienza University of Rome (RO) hosts a Spermoteque/Carpoteque, which was organized by Gustavo Bonaventura (1902–1976). The purpose of this paper is to describe the heritage of B...

The interest in the ecological role of weed communities within arable fields has increased greatly in recent years.
