Experimental evolution is relevant to ecology because it can connect physiology, and in particular metabolism, to questions in ecology. The investigation of the linkage between the environment and the evolution of metabolism is tractable because these experiments manipulate a very simple environment to produce predictable evolutionary outcomes. In doing so, microbial selection experiments can e...

Phenology, as one of the most important subjects of ecology, is the study of periodic plant life cycle events and how these are influenced by variations in climate and ecological conditions. In this research, phonological observations of 5 species (Prunus dulcis, Prunus avium, Prunus armeniaca, Pyrus communis, Prunus domestica) were studied in Iranian orchard of National Botanical Garden of Ira...

the “driving force - pressure - state - impact – response” modeling framework isadopted to consider the formation mechanisms of environmental risks and the requirements ofecological environment protection. moreover, a systematical index system and evaluation model forthe measurement of the coastal ecological security level is put forward in this paper to assess thestate of coastal ecological en...

Research on the interactions between evolutionary and ecological dynamics has largely focused on local spatial scales and on relatively simple ecological communities. However, recent work demonstrates that dispersal can drastically alter the interplay between ecological and evolutionary dynamics, often in unexpected ways. We argue that a dispersal-centered synthesis of metacommunity ecology and...

Article history: Received 31 December 2004 Received in revised form 3 December 2005 Accepted 14 December 2005 Ecological data are difficult to analyze due to complexity residing in the ecological systems with the variables varying in non-linear fashion. Efficient methods are required to properly extract information out of the complex data. Wavelets have good time–frequency (timescale) localizat...
