Abstract Tropical cyclones (TCs) are known to bring heavy rainfall, strong winds and severe storm surges simultaneously, resulting in tremendous damage beyond the effects of a single hazard. However, compound impacts TC multi‐hazards remain unexplored macroeconomic assessments. Here, we provide empirical evidence on multi‐hazard economic losses for first time. We used national panel provincial ...

investigating species diversity and richness is essential for defining conservation priorities. in addition, determining landscape parameters influencing species diversity and richness is important for selecting and designing parks and protected areas. kohgiluyeh & boyer ahmad province is a mountainous region, comprises hills, mounds, forests and plains. this vast province has high species dive...

Habitat heterogeneity plays an important role in increasing species diversity. Heterogeneity of habitats and protected areas can increase the ability of species to adapt to climate change. It is expected that appropriate heterogeneity is necessary for sustainability of protected areas. The influence of altitude on parameters such as temperature and precipitation and the role of microclimates in...

Background and Aim: Climate change on the earth is changing faster than ever before in the history. Cities are highly vulnerable to this climate change. Therefore, the present study aimed to investigate climate change in the metropolis of Tehran during the period 1991-2020 and help understand the limitations that cities may have in confronting climate change. Materials and Methods: This descri...

One of the most important issues in rangeland management is the estimation of carrying capacity. To estimate range production, we need to use a large number of sample plots to clip plants in a sampling scheme; therefore, due to vast area of rangelands and time and cost limitations, direct estimation of rangeland production by sampling plots is almost impossible. Since there is a strong relation...
