Industrial longline fishing can be understood as a case study of the cultural, economic, environmental and social impacts of unsustainable fishing technology. While much attention has been attributed to the impact of industrial longlines on the marine ecosystem, little is known about the impact of longline fishing on local food security, employment, cultural belief systems and traditions, reven...

Marine renewable energy is playing an increasing significant role in many parts of the world, mainly due to a rise in the awareness of climate change, and its detrimental effects, and the increasing cost of natural resources. The Severn Estuary, located between South West England and South Wales, has a tidal range of up to 14 m which makes it the second highest tidal range in the world. There a...
Coastal ecosystems of Bushehr are shallow environments subject to human impacts, including shrimp aquaculture and urban expansion activities. A spatial-temporal study was conducted in order to assess the actual ecological status of the creeks, estuary and marine sites on the basis of their taxonomic composition and density of mesozooplankton. Zooplankton species distribution and abundance data ...
Mediterranean ecosystems support important processes and functions that bring direct benefits to human society. Yet, marine ecosystem services are usually overlooked due to the challenges in identifying and quantifying them. This paper proposes the application of several biophysical and ecosystem modelling approaches to assess spatially and temporally the sustainable use and supply of selected ...
casted the increasing need for fisheries managers to take species interactions into account. It is now widely recognized that ecosystem effects need to be considered in managing fisheries (Pauly 1998, Beamish and Mahnken 1999, Gislason et al. 2000). Steele (1996) concluded that a “regime shift in fisheries management” is required if one is to manage fisheries successfully in the context of ecos...
Marine ecosystem services refer to benefits that people obtain from marine ecosystem. Understanding temporal evolution of these services is a fundamental challenge of natural resource management in marine ecosystems. Yellow Sea is one of the most intensely exploited shallow seas in the Northwest Pacific Ocean. In this study, we analyzed the value of the four classes services (provisioning servi...
We study the problem of assessing the agreement between two methods with any number of replicated observations using linear mixed effects (LME) model in a doubly multivariate set-up. This method can also be used in the case of unbalanced designs when number of replications for each patient is unequal, as well as when the number of replications for each patient by respective methods is unequal. ...
A new approach toward understanding marine ecosystems has emerged through the integration of ecological physiology and macroecology. This multidisciplinary approach, titled here marine macrophysiology, facilitates unique insight into the foundation of macro-scale ecological patterns, such as biogeographic distributions, via examination of functional attributes of marine organisms across large s...
