During the floristic explorations conducted in 2022–2023 different forest areas of northeast region Bangladesh, some specimens family Lauraceae were collected. Following critical examination, these have been identified as belonging to species Litsea kurzii, stocksii, and variabilis Lauraceae. These are new flora Bangladesh. A detailed taxonomic description, including data on ecology, distributi...

The precriber's first problem is : On what basis to make the choice? On the basis of the established name of the comapny? On the basis of the retail price of the drug? In the recent past, the drug were required to be prescribed by their pharmacological name, with the prescribing doctor having the option to mention the company's name alongside. For many reasons, this practice did not catch on. O...

the diversity and richness of species are of important components to evaluate the health of ecologic system of rangelands. this research was conducted to investigate the biodiversity in riparian and neighboring areas via comparison of indices in javaherdeh rangeland of ramsar. plot-transects was randomly used to estimate diversity, richness, dominance, and evenness indices in two regions. multi...

species diversity is one of the important characteristics shows rangeland ecosystems changes, which isalready under effects of management practices. thus, this research was conducted to study speciesdiversity variation and assess suitable distributive abundance model in three rangeland sites in westazerbaijan. these sites were almost similar in environmental properties and differ in view point ...

Understanding the maintenance of high tropical tree species diversity requires disentangling the effects of habitat vs. geographic distance. Using floristic, topographic, and soil nutrient data from 105 0.6-ha plots in mixed dipterocarp forest throughout Sarawak, Malaysian Borneo, we explore the degree to which floristic patterns are habitat-driven from local to landscape scales. We assess how ...
