The success or failure of many organisms to respond to the challenges of habitat destruction and a warming climate lies in the ability of plant species to disperse between isolated habitats or to migrate to new ranges. European semi-natural grasslands represent one of the world’s most species-rich habitats at small scales, but agricultural intensification during the 20th century has meant that ...

Landscape diversification is a key element for the development of sustainable agriculture. This study explores whether the implementation of habitats for pest natural enemies enhances conservation biological control in an adjacent field. In the present study conducted in Gembloux (Belgium) in 2016, the effect of two different habitats (wildflower strips and a forest) and aphid abundance on the ...

Background & Aim: Myrtle (Myrtus communis L.), is an important medicinal plant that is used for pharmacological uses and conservation of environments (for example preventing the soil erosion) regards to its specific condition habitat. Experimental: In this research, phytochemical variations of the essential oils from different populations of myrtle collected from Fars (Saydan, Cheshme-Ali, and ...

Zoonotic transmission of novel viruses represents a significant threat to global public health and is fueled by globalization, the loss of natural habitats, and exposure to new hosts. For oronaviruses (CoVs), broad diversity exists within bat populations and uniquely positions them to seed future emergence events. In this review, we explore the host and viral dynamics that shape these CoV popul...

Anthropogenic habitats are increasingly prevalent in coastal marine environments. Previous research on sessile epifauna suggests that artificial habitats act as a refuge for nonindigenous species, which results in highly homogenous communities across locations. However, vertebrate assemblages that live in association with artificial habitats are poorly understood. Here, we quantify the biodiver...

Acipenser stellatus (stellate sturgeon) represents a sturgeon species of great importance for the scientific community and fishermen that has been intensively captured for decades. Besides of overfishing and poaching, their reproduction sites have been destroyed and their natural habitats were affected by pollution. In consequence, wild populations of stellate sturgeon have decreased dramatical...

Background & Aim: In the present research, we investigated phytochemical characteristics of two important species of Verbascum genus. Enormous reconnaissance and field surveys were conducted to identify the most important natural habitats of Verbascum species in Kohgiluyeh va Buyerahmad province, southern Iran. Experimental: The aerial parts of Verbascum songaricum a...

Development of roads can have deleterious effects on natural habitats containing species of conservation concern. Fragmentation of habitat into small, non-contiguous patches may result in dramatic population declines. Thus appropriate studies quantifying ecological impacts of roads at landscape scale are essential. In this study, the Spatial Road Disturbance Index (SPROADI) was applied for the ...

Identifying herbaceous species and their composition at forest road edges and skid trails is an urgent task to prevent changes of natural and native composition of species and invasion of exotic species. The present study aimed to evaluate the herbaceous species cover grown on the forest road surface, cut and fill slopes and skid trail surface and their comparison with inside forest in order to...

In Europe 15,000 patients receive larval therapy for wound treatment annually. Over the past few years, clinical studies have demonstrated the success of larvae of Lucilia sericata as debridement agents. This is based on a combination of physical andbiochemical actions. Laboratory investigations have advanced our understanding of the biochemical mechanisms underlying the beneficial effects of l...
