Ecosystem-Based Fishery Management

Ecosystem-based piscary management (EBFM) may be a new direction for piscary management, basically reversing the order of management priorities so management starts with the system instead of a target species. EBFM aims to sustain healthy marine ecosystems and also the fisheries they support. Pikitch et al. describe the potential edges of implementation of EBFM that, in their read, so much outweigh the difficulties of constructing the transition from a management system supported increasing individual species.

Organisms as Ecosystem Engineers

Interactions between organisms are a serious determinant of the distribution and abundance of species. Ecology textbooks (e.g., Ricklefs 1984, Krebs 1985, Begon et al. 1990) summarise these necessary interactions as intra- and interspecies competition for abiotic and organic phenomenon resources, predation, interdependency and mutuality. prominently lacking from the list of key processes in most text books is that the role that several organisms play within the creation, modification and maintenance of habitats. These activities don’t involve direct biological process interactions between species, however they’re withal necessary and customary. [2]

Assessing ecosystem health

Evaluating scheme health in relevance the ecological, economic and human health spheres needs group action human values with biophysical processes, Associate in Nursing integration that has been expressly avoided by standard science. the sector is advancing with the articulation of the linkages between act, regional and world environmental amendment, reduction in ecological services and therefore the consequences for human health, economic chance and human communities. Increasing our understanding of those interactions can involve a lot of active collaboration between the ecological, social and health sciences. In this, ecologists can have substantive and chemical action roles. [3]

Ecosystem-bedrock interaction changes nutrient compartmentalization during early oxidative weathering

Ecosystem-bedrock interactions power the biogeochemical cycles of Earth’s shallow crust, supporting life, stimulating substrate transformation, and encouragement organic process innovation. whereas aerobic  processes have dominated half terrestrial history, the relative contribution of the part and its chemical fingerprints on Earth’s developing regolith are still poorly strained. Here, we have a tendency to report results from a biennial inchoate weathering experiment. [4]

Enzyme–based Assay for Toxicological Evaluation of Soil Ecosystem Polluted with Spent Engine Oil

Aim: during this study, the experiment was designed to analyze the result of contamination of soil scheme with spent engine oil at numerous concentrations.

Design: Soil samples were obtained from installation University of African nation Nsukka whereas spent engine oil was obtained from the Mechanic Village, Nsukka. check tubes tagged one- seven containing numerous percentages of spent engine oil 1.0, 1.5, 2.0, 2.5, 3.0, 3.5% w/w (oil-soil mixture); and into the seventh tube, the management contained solely the soil sample. The study was designed for thirty-five-days (0, 14, twenty eight and thirty five day) at numerous degrees of pollution by spent oil. [5]
