Functions include calculating Extent of Occurrence (EOO), Area of Occupancy (AOO), mapping species ranges, species distribution modelling using climate and land cover and calculating the Red List Index for groups of species.

Abstract:

The IUCN Sampled Red List Index (SRLI) is a policy response by biodiversity scientists to the need to estimate trends in extinction risk of the world's diminishing biological diversity. Assessments of plant species for the SRLI project rely predominantly on herbarium specimen data from natural history collections, in the overwhelming absence of accurate population data or detailed distribution maps for the vast majority of plant species. This creates difficulties in re-assessing these species so as to measure genuine changes in conservation status, which must be observed under the same Red Lis

Abstract:

Biodiversity loss is a global problem, accelerated by human-induced pressures. In the marine realm, one of the major threats to species conservation, together with climate change, is overfishing. In this context, having information on the conservation status of target commercial marine fish species becomes crucial for assuring safe standards. We put together fisheries statistics from the FAO, the IUCN Red List, FishBase, and RAM Legacy databases to understand to what extent top commercial species’ conservation status has been assessed. Levels of assessment for top-fished species were higher th

Abstract:

The World Conservation Union (IUCN) Red List is widely recognized as the most authoritative and objective system for classifying species by their risk of extinction. Red List Indices (RLIs) illustrate the relative rate at which a particular set of species change in overall threat status (i.e. projected relative extinction-risk), based on population and range size and trends as quantified by Red List categories. RLIs can be calculated for any representative set of species that has been fully assessed at least twice. They are based on the number of species in each Red List category, and the numb

Field data were collected using a “Point Count Approach” in transects which were laid in different habitat types (Forest, Agricultural land & Wetland). Shannon-Wiener and Margalef Diversity Indices were used to calculate the diversity of birds and Pielou’s Evenness was used to calculate the

Abstract:

The article highlights the principles of sozological analysis of lichens to form lists of threatened species, determination of their conservation status, and subsequent inclusion into regional Red Data Books. The analysis is useful when we lack information on distribution, quantitative indicators, and population structure of species to be protected. The lichen-adapted sozological matrix includes biological, ecological, biogeographical, sozological and economic characters. To approbate the method, we calculated the sozological index for four lichen species included into the new list of protecte

Abstract:

Mount Ungaran is one of the dormant volcanoes in Central Java. The condition of the unspoiled forest in the Mount Ungaran area is a good habitat for fauna, including birds. There are several hiking trails traversed by mountain climbers, one of them is the Promasan hiking trail. This study aims to determine the diversity of bird species and identify their conservation status on the Promasan hiking trail. Data were colected by Indices Ponctuels d'Abondance (IPA), Line Transect, and Point Count methods. Bird species diversity was determined by the Shanon index. Determination of bird conservation

Abstract:

The dynamics of changes of Chlorophyll vegetation index (CVI) and Red-edge chlorophyll index (CIRE) for plant cover during the springsummer period on river floodplains has been studied. Landscape sections with high photosynthetic activity were identified through GIS analysis. Various types of plant communities that accumulated chlorophyll during certain time periods, have been determined, as well as the areas of these types. A list of measures was proposed for plots of vegetation with an active accumulation of chlorophyll, and for plots where it is observed decreasing of its level, as well as

Abstract:

Critical as they are for humans and nature, freshwater ecosystems are threatened—but the extent and depth of these threats are not well understood, especially if essential biodiversity data are lacking. Any policy aimed at protecting such ecosystems must first assess the threat factors and the potential harm, well before proposing conservation measures such as the creation and development of Protected Areas (PAs). These assessments must be done using a deep and sound knowledge of the actual and potential biodiversity variables. Freshwater ecosystems have been largely neglected in traditional P

Abstract:

Avifaunal diversity is the measure of species diversity via species richness and evenness. To this aim, avifaunal survey was conducted in the Institute of Forestry Complex, Hetauda from November 2017 to June 2018. Using line transect and point count methods, 132 species of birds were recorded, representing 15 orders and 44 families. Three species of these birds are in IUCN Red List while 90, 27 and 15 species are residential, visitor and migrant respectively. Higher Shannon diversity index (4.47) and Margalef index (18.78) indicate marked diversity and richness of bird species. A high value ca
