The toxicity of heavy metals in sediments of the Nayband Bay and Asaluyeh region and potential ecological risk to sediment organisms assessed. Three stations with different degrees of vulnerability of South Pars Oil and Gas Activities (1: Control - 2: medium affected and 3: severely affected) were selected in the study area. Sediment sampling at each station in both cold and hot seasons (2010) ...

The presence of multiple interacting threats to biodiversity and the increasing rate of species extinction make it critical to prioritize management efforts on species and communities that maximize conservation success. We implemented a multi-step approach that coupled vulnerability assessments evaluating threats to Florida taxa such as climate change, sea-level rise, and habitat fragmentation ...

In this paper, we explore the resilience and vulnerability of livelihoods within two different socio-ecological dryland contexts of Botswana over the last 30 years. We draw on primary field data sources, including oral histories, livelihood surveys, ecological surveys, as well as documented evidence of environmental, socioeconomic and institutional dynamics, to identify a broad range of activit...

Using the constituent elements of vulnerability, an evaluation index system for the ecological vulnerability of coastal areas under oil spill stress is established based on “Sensitivity–Adaptive Capacity-Exposure”. After selecting a gulf in China as the main case study in this work, the cluster analysis and reference method were applied in grading and value assigning for all indexes. In additio...

Assessment of ecoenvironmental vulnerability plays an important role in the guidance of regional planning, the construction and protection of ecological environment, which requires comprehensive consideration on regional resources, environment, ecology, society and other factors. Based on the driving mechanism and evolution characteristics of ecoenvironmental vulnerability in cold and arid regi...

Strong karstlize effect forming surface and underground double-space structure in karst area, what resulting groundwater systems are extremely sensitive to outside interference. This article mainly focuses on the vulnerability assessment of karst groundwater, proposing that the vulnerability assessment of karst groundwater should be considered from three perspectives: the inherent vulnerability...

Climate-driven changes to environmental conditions are driving severe declines of coral reef ecosystems. Current climate vulnerability estimates commonly focus on ocean warming and typically overlook ecological responses or use broad proxies represent responses, leading management decisions based incomplete views futures. We explore four underdeveloped aspects assessments make the following rec...
