seed bank is a central topic for plant community restoration. we determined the potential and regeneration capacity of soil seed banks of woody plant patches in conservation of the vegetation in an alpine habitat, since vegetation has completely disappeared in some sites by intensive grazing in the habitat. the study was done in mountainous area of alborz in iran. a total of 20 individual shrub...

The rapid development of urbanization has caused many ecological issues and greatly threatened the sustainable human society. construction security patterns (ESPs) offers an effective way to balance conservation urbanization. This study aimed take highly urbanized city Shenzhen, China, as a area construct urban ESP put forward suggestions for security. Ecological sources were identified through...

Land acquisition is a common practice for establishing and expanding protected areas such as wildlife refuges. However, the socioeconomic feasibility and ecological consequences of an acquisition project are rarely assessed before the project is executed. In this paper, a socio-economic-ecological model (SEELAND) was developed to simulate the socioeconomic feasibility and ecological consequence...

The widespread degradation of lotic ecosystems has prompted extensive river restoration efforts globally, but many studies have reported modest ecological responses to rehabilitation practices. The functional properties of biotic communities are rarely examined within post-project appraisals, which would provide more ecological information underpinning ecosystem responses to restoration practic...

Understanding Allee effect has crucial importance for ecological conservation and management because it is strongly related to population extinction. Due to various ecological mechanisms accounting for Allee effect, it is necessary to study the influence of multiple Allee effects on the dynamics and persistence of population. We here focus on organism-environment feedback which can incur strong...

rangeland ecosystem contains various patches with different functions. structural and functional characteristics of rangeland patches are changed by management practices and can be used to interpret management effects. the structural and functional characteristics of fertilized patches in two rangeland ecosystems of ghareh ghir and maraveh tapeh were measured and analyzed in this study. a group...

Many services generated by forest ecosystems provide essential support for human well-being. However, the vulnerability of these services to environmental change such as forest fragmentation are still poorly understood. We present spatial modeling of the generation of ecosystem services in a human-dominated landscape where forest habitat patches, protected by local taboos, are located in a matr...

1. introduction environmental changes can be monitored at many scales but the scale of landscape and region has more information in support of sustainable spatial planning. the availability of remote sensing imagery provides multi-scale observation with periodic repetitions over time. landscape and regional scales are adequately covered by satellite images. remote sensing images provide non-ave...
