Mashkova IV, Krupnova TG, Kostryukova AM, Vlasov NE. 2018. Short Communication: Biodiversity of weeds in Ilmen State Reserve, Russia. Biodiversitas 19: 106-111. Weeds are a synanthropic flora. Human exposure to the natural landscape leads to the spread of synanthropic plant species, so weeds begin to occupy a significant place in the structure of ecosystem biodiversity. The aim of this study was to investigate the weeds biodiversity structure and to assess the extent of invasion of weeds into the territory of the Ilmen State Reserve in South Urals, Russia. This paper presents the results of study of weeds during the vegetation period in 2013–2017. Fifty one species of weeds distributed in four genera and six families were found on the territory of the Southern Forestry of the Ilmen State Reserve. Besides, the differences between species diversity of weeds on three types of roads (gravel, earth and foot) and on two types of forests (birch and pine) were also discovered in this study . The greatest degree of invasion was discovered for foot roads. It was noted that pine forest is the most resistant the invasion of weeds.

Abstract. Elfrida, Mubarak A, Suwardi AB. 2020. Short Communication: The fruit plant species diversity in the home gardens and their contribution to the livelihood of rural communities in Tenggulun Sub-district, Aceh Tamiang, Indonesia. Biodiversitas 21: 3670-3675. Home gardens have a significant potential to improve food security and offer a contribution to household income for communities in rural areas. The aim of this study was to assess the diversity of fruit plant species in the home gardens and their contribution to the livelihood of rural communities in Tenggulun Sub-district, Indonesia. The study was conducted in three villages of Tenggulun Sub-district, Aceh Tamiang District, namely Tenggulun, Selamat, and Simpang Kiri. Extensive field surveys, plant collections, and interviews with local communities were conducted, involving 350 households, using random sampling methods. A total of 39 fruit plant species consisting of 23 genera and 17 families were recorded at the three villages. Sixteen species, i.e., A. muricata, A. jiringa, Artocarpus integer, Averrhoa bilimbi, Baccaurea motleyana, Carica papaya, Citrus aurantifolia, Citrus hystrix, Garcinia mangostana, Mangifera indica, Manilkara zapota, Musa x paradisiaca, Nephelium lappaceum, Psidium guajava, Spondias pinnata, and Syzygium aqueum were the most frequently recorded in all of the villages. In addition to being used as food, the fruit plants in the study area were also used as medicines, fodder, fuelwood, and household items. The fruit plant species have a significant role in supporting household livelihoods to improve food security and potentially offer a household income for the rural community in the study area.

AbstractMountains are rugged structures in the landscape that are difficult to delineate. Given that they host an overproportional fraction of biodiversity of high ecological and conservational value, conventions on what is mountainous and what not are in need. This short communication aims at explaining the differences among various popular mountain definitions. Defining mountainous terrain is key for global assessments of plant species richness in mountains and their likely responses to climatic change, as well as for assessing the human population density in and around mountainous terrain.
