The seascape nursery: a novel spatial approach to identify and manage nurseries for coastal marine fauna
Coastal marine and estuarine ecosystems are highly productive and serve a nursery function for important fisheries species. They also suffer some of the highest rates of degradation from human impacts of any ecosystems. Identifying and valuing nursery habitats is a critical part of their conservation, but current assessment practices typically take a static approach by considering habitats as i...
متن کاملMapping Reef Fish and the Seascape: Using Acoustics and Spatial Modeling to Guide Coastal Management
Reef fish distributions are patchy in time and space with some coral reef habitats supporting higher densities (i.e., aggregations) of fish than others. Identifying and quantifying fish aggregations (particularly during spawning events) are often top priorities for coastal managers. However, the rapid mapping of these aggregations using conventional survey methods (e.g., non-technical SCUBA div...
متن کاملDietary ecology of the Portunus segnis (Forskal, 1775) in the coastal waters of Hormozgan Province, Iran
In this study, the feeding habits of blue swimming crab (Portunus segnis) in the Northeast Persian Gulf were investigated. A total of 722 specimens were collected using bottom trawl. The samples were transferred to the laboratory in order to further analysis after freezing. All individuals were dissected and their stomach was removed. The results showed the vacancy index of stomach (CV) was 34....
متن کاملThe concept of biotope in marine ecology and coastal management.
The term "biotope" was introduced by a German scientist, Dahl in 1908 as an addition to the concept of "biocenosis" earlier formulated by Möbius (1877). Initially it determined the physical-chemical conditions of existence of a biocenosis ("the biotope of a biocenosis"). Further, both biotope and biocenosis were respectively considered as abiotic and biotic parts of an ecosystem. This notion ("...
متن کاملExperimental plant ecology as an approach in coastal population biology
The relations between a large number of scientific subdisciplines within the population biology of plants are presented. This overview in which the holistic and reductionistic approaches are discussed, emphasizes that conflicts between both attitudes are artificially raised. In fact, the one approach must support the other in order to trace the relations between the individual plants and their ...
