Ecological processes that can realistically account for network architectures are central to our understanding of how species assemble and function in ecosystems. Consumer species are constantly selecting and adjusting which resource species are to be exploited in an antagonistic network. Here we incorporate a hybrid behavioural rule of adaptive interaction switching and random drift into a bip...

Cities all over the world are challenged by increasing the quality of life of urban citizens in order to ensure sustainable urban development. However, a lot of policies and planning fail in integrating environmental aspects in a way that makes them applicable for design leading to rather unsustainable developments. This paper presents an approach to integrate ecological parameters into urban d...

A series of functional variables, including biomass and hymenial area, were obtained for more than 4800 individual macrofungal sporocarps and correlated with a set of ecological parameters characterizing soil, climate and forest structure in four different forest types of Costa Rica. The idea behind this project was to document macrofungi over a three-year period with the objective of generatin...

The cross-scale resilience model was developed in ecology to explain the emergence of resilience from the distribution of ecological functions within and across scales, and as a tool to assess resilience. We propose that the model and the underlying discontinuity hypothesis are relevant to other complex adaptive systems, and can be used to identify and track changes in system parameters related...

Given multiple images that describe chaotic reaction-diffusion dynamics, parameters of a partial differential equation (PDE) model are estimated using autosynchronization, where parameters are controlled by synchronization of the model to the observed data. A two-component system of predator-prey reaction-diffusion PDEs is used with spatially dependent parameters to benchmark the methods descri...

(Vieglais et al., 2000). Museum data are high quality because voucher specimens can be examined if identification is questionable. However, like all point data, museum specimens provide only a limited view of the actual species' range (Krohn, 1996), hence the need for predictive approaches. A limited number of ecological data sets are also available, worldwide, including physio-chemical paramet...

Theoretical models of interaction between wild and domestic reindeer (Rangifer tarandus; caribou in North America) can help explain observed social–ecological dynamics of arctic hunting and husbandry systems. Different modes of hunting and husbandry incorporate strategies to mitigate effects of differing patterns of environmental uncertainty. Simulations of simple models of harvested wild and d...

with regard to the mutual relations between plant and soil as the main component of rangeland ecosystems, this research has been identified the indicator species in environmental conditions of dry regions as the most important tools in ecological management of these ecosystems. therefore the steppe and dry rangelands of kooh - e- namak in qom province was selected. sampling was done by plot in ...
