Information use shapes range expansion dynamics into environmental gradients
Globally, geographic distributions of species are dynamic and strongly influenced by dispersal. Vice versa, range dynamics feed back and may select for increased dispersal. This interplay almost universally happens across environmental gradients which can directly impact the fitness of organisms, but also provide individuals with information on the environmental changes. However, the organisms’...
متن کاملPlant communities partially refl ect environmental gradients in humanized landscapes: a case study in the Llobregat delta marshes
This study took place in a vegetation mosaic of the Llobregat delta (near Barcelona, Spain), which includes both natural and spontaneously restored coastal marshes. We used a dataset comprising vegetation relevés, soil parameters and water table conditions, and explored their correlation. More precisely, we classifi ed the relevés into three phytosociological alliances (namely Phragmition commu...
متن کاملLand use planning for land management using the geographic information system (GIS) in the Loumir watershed of Guilan province in northern Iran
Land use planning is a science that determines the type of land use through studying the ecological character of the land as well as its socio-economic structure. It is possible to plan for the appropriate use of the land and to enhance the present management of the land use by utilizing Geographical Information System (GIS). To this end, our investigators identified and took steps toward devel...
متن کاملLong-term ecological dynamics: reciprocal insights from natural and anthropogenic gradients.
Many ecological dynamics occur over time-scales that are well beyond the duration of conventional experiments or observations. One useful approach to overcome this problem is extrapolation of temporal dynamics from spatial variation. We review two complementary variants of this approach that have been of late increasingly employed: the use of natural gradients to infer anthropogenic effects and...
متن کاملAssessment of Spatial and Temporal Variations in Water Quality Dynamics of River Ganga in Varanasi
River Ganga is one of the prime sacred National Rivers of India, closely associated with economic, social, and cultural heritage of Indian people. Recently, it has been subjected to immense degradation and pollution as a result of receiving huge amounts of domestic and industrial wastewater as well as religious ritual activities and surface runoff. The present study attempts to study spatial an...
