Soundscape analysis, using acoustic indices, provides researchers with valuable ecological information to assess biodiversity, species behavior, and noise pollution. In this study,  to analyze biophonies and anthrophony in six urban parks in  Isfahan city in spring, six acoustic indices, including Acoustic complexity index (ACI), Acoustic Diversity Index (ADI), Acoustic Evenness Index (AEI), an...

Grasslands play important roles in ecosystem production and support a large farming and grazing industry. An accurate and efficient way is needed to estimate grassland health and production for monitoring and adjusting management to get sustainable products and other ecosystem services. Previous studies of grasslands have shown varying relationships between productivity and biodiversity, with m...

Introduction and purpose: Ticks as biological vectors and reservoirs of diseases, such as Crimean-Congo hemorrhagic fever (CCHF), have an important role in the transmission of pathogens to humans and animals. In this regard, this study aimed to determine the biodiversity indices, distribution, and fauna of the vectors of CCHF in Ahvaz, Iran. Methods: The tick samples were collected and identif...

Widespread concerns about global biodiversity loss have led to a growing demand for indices of biodiversity status. Today, climate change is among the most serious threats to global biodiversity. Although many studies have revealed phenological responses to climate change, no long-term community-level indices have been developed. We derived a 250-year index of first flowering dates for 405 plan...

Biological diversity, also known as biodiversity, is an important criterion for measuring the value of an ecosystem. As biodiversity is closely related to human welfare and quality of life, many efforts to restore and maintain the biodiversity of species have been made by government agencies and non-governmental organizations, thereby drawing a substantial amount of international attention. In ...

The lack of urgent action to reverse biodiversity loss is partly due the complex nature as a feature our planet. Subsequently, policymakers receive an often-confusing variety narratives on why matters, which makes it difficult link and risks attainment sustainable development. Making this clearer calls for multidimensional perspective reassess what we value, facilitate mainstreaming support nat...
