Empirical evaluation of observation scale effects in community time series

Article Abstract:

The changes in interpretation of community interactions that occur when observation scale is restricted in two common ways are discussed such as when data collection is at increasingly course scale and secondly when exclusion of data is collected is in winter months. It was concluded that explicit consideration of time lags in biotic response is necessary to understand relative importance of abiotic and biotic factors, and that sampling regime can therefore strongly influence interpretations of community dynamics.

Towards maturation of the population concept

Article Abstract:

The population represents the centrepiece of biological thought and practice. Recognizing and understanding populations will entail confronting them in their full complexity, in particular, their inherent properties of hierarchy and vagueness and these two features represent the components of an emerging and mature synthesis.

The frequency spectrum of structured discrete time population models: Its properties and their ecological implications

Article Abstract:

A lot of research effort is developed to the study of the interaction between environmental noise and discrete time nonlinear dynamical systems. The analysis hence highlights the complexity of the inverse problem and the role of factors other than color in the persistence of populations.
