Using landscape moderation insurance and Intermediate Disturbance Hypothesis (IDH) as frameworks, this study assessed the response of local assemblage among different land use regimes (mean β-diversity), using the Jaccard dissimilarity matrix in contrasting Human Modified Forest Landscapes (HMFLs). The study was conducted at the relatively simplified Mafhela Forest Reserve and the complex Thathe Vondo Forest Reserve in South Africa. The patterns of overall β-diversity between HMFL and State-protected Indigenous Forests (SIF) were compared and the leading change drivers were then untangled. This study found that human disturbance affects mean β-diversity of local assemblages among land use regimes between the two HMFLs in an ecologically contrasting manner. The HMFL in Mafhela Forest Reserve had distinct local assemblages among land use regimes and did not conform to the expectation of IDH. On average, HMFL had the same average local species richness as SIF, mainly due to change in species composition (species replacement) induced by land use disturbance. Land use intensity gradient was the leading change driver to explain the overall β-diversity of the Mafhela Forest Reserve. The findings in the Thathe Vondo Forest Reserve were in contrast with the Mafhela Forest Reserve. Although on average the HMFL had the same local species richness as SIFs, this was mainly due to a trade-off of species gain in trees along the rivers and streams and species loss in Culturally Protected Areas (sacred forests) (CPA) as expected by IDH. The contrasting findings imply that the effectiveness of any alternative conservation strategy is context-dependent. The resilience of local assemblages and conservation value of HMFL depends on the condition of the overall forest landscape complexity and cannnot be captured by one theory, nor by one species diversity matrix (e.g., β-diversity or Richness). It thus demands the application of complementary theoretical frameworks and multilevel modeling.

Abstract Background Species with direct uses, such as sources of food, shelter, building material and medicine tend to have more specific local names. But could the same apply for species that people fear? Methods To address this question, here we explore the behavior and perception of species diversity and dangerousness through a survey of 1037 households in nine villages in Cabo Delgado, northern Mozambique. We compare people’s knowledge of snakes with that of lizards and amphibians. Results We find that northern Mozambicans know four to five times more local names for snakes than for lizards and frogs, despite the local species richness of snakes being comparable to the diversity of lizards and frogs. We further find that local knowledge was on par with the academic literature regarding snakebite symptoms. Conclusions Our results suggest that fear can increase the level of specificity in naming species among indigenous communities, which could lead to biases in the mapping and protection of species that include data from citizen reports.

Ornamental shrubs are one of the elements of the formation of the park environment and an integral part of urban landscaping. The paper presents the results of studying the species diversity of shrubs in park plantations in the city of Voronezh. The range includes more than 30 species, decorative forms and varieties of plants. Deciduous species are predominant, while coniferous species account for not much more than 10 %. Deciduous shrubs growing in the parks of the city of Voronezh belong to 14 families. Among them, there are beautiful flowering and decorative deciduous species, as well as plants with attractive fruits. Coniferous species belong to two families-pine and cypress. The cypress family is characterized by the greatest species (form, variety) diversity. The most popular types and varieties of coniferous trees are Western thuja "Smaragd", Western thuja "Danika", Cossack juniper, Cossack juniper"Tamariscifolia". The main types of shrub plantings in park stands are hedges and row plantings. The most common hedges are made of brilliant dogwood and Wanguttaspirea. Less often, groups and tapeworms are used in park plantings. The analysis of the geographical origin of shrubs showed that the largest number of species are introduced − their participation is more than 90%, the share of local species is less than 10%.
