the aim of this study was determination of abundance and biodiversity of zooplankton community at integrated fish culture of grower and fingerling fishes at east of golestan province, gonbade kavous city. sampling was done monthly at 6 ponds during one season culture from june to november 2011. during six month study period, 4 groups and 27 genuses were identified. between recorded groups, 12 g...

Marine protected areas (MPAs) have been shown to increase long-term temporal stability of fish communities and enhance ecosystem resilience to anthropogenic disturbance. Yet, the potential ability of MPAs to buffer effects of environmental variability at shorter time scales remains widely unknown. In the tropics, the yearly monsoon cycle is a major natural force affecting marine organisms in tr...

What is the current distribution of the salmon? Has the population of the European otter declined? Which alien species have most recently been discovered in Germany? The Biodiversity Atlas gives the answers. Since 2006, the Project Group AG Biodiversity has been developing the Atlas at the Bremen University of Applied Sciences in cooperation between the Fish Ecology Lab and the Institute of Inf...

Current evidence indicates that, compared with loss of biodiversity in freshwater and terrestrial ecosystems, the rate of loss in marine systems is relatively slow (N.K. Dulvy – Recent marine extinctions, this meeting). This is not a cause for complacency, and the rate of loss is probably underestimated, but it challenges us to explain why protection of marine biodiversity is an urgent concern,...

Dams and diversions are a primary threat to freshwater fish biodiversity, including the loss of species restructuring communities, often resulting in taxonomic homogenization (increased similarity) over time. Mitigating these impacts requires strong scientific understanding both patterns drivers diversity. Here, we test whether different components biodiversity have changed response major dam c...
