Ecological models supporting environmental decision making: A strategy for the future Ecological models supporting environmental decision making: A strategy for the future
Ecological models are important for environmental decision support because they allow the consequences of alternative policies and management scenarios to be explored. However, current modeling practice is unsatisfactory. A literature review shows that the elements of good modeling practice have long been identified but are widely ignored. The reasons for this might include lack of...

A consumer-resource approach to the density-dependent population dynamics of mutualism A consumer-resource approach to the density-dependent population dynamics of mutualism
Like predation and competition, mutualism is now recognized as a consumer resource (C-R) interaction, including, in particular, bi-directional (e.g., coral, plant- mycorrhizae) and uni-directional (e.g., ant-plant defense, plant-pollinator) C-R mutualisms. Here, we develop general theory for the density-dependent population dynamics of mutualism based on the C-R mechanism of...

Modeling seasonal dynamics of small fish cohorts in fluctuating freshwater marsh landscapes Modeling seasonal dynamics of small fish cohorts in fluctuating freshwater marsh landscapes
Small-bodied fishes constitute an important assemblage in many wetlands. In wetlands that dry periodically except for small permanent waterbodies, these fishes are quick to respond to change and can undergo large fluctuations in numbers and biomasses. An important aspect of landscapes that are mixtures of marsh and permanent waterbodies is that high rates of biomass production occur in...

Ecological hierarchies and self-organisation - Pattern analysis, modelling and process integration across scales Ecological hierarchies and self-organisation - Pattern analysis, modelling and process integration across scales
A continuing discussion in applied and theoretical ecology focuses on the relationship of different organisational levels and on how ecological systems interact across scales. We address principal approaches to cope with complex across-level issues in ecology by applying elements of hierarchy theory and the theory of complex adaptive systems. A top-down approach, often characterised by...

Challenges and opportunities for integrating lake ecosystem modelling approaches Challenges and opportunities for integrating lake ecosystem modelling approaches
A large number and wide variety of lake ecosystem models have been developed and published during the past four decades. We identify two challenges for making further progress in this field. One such challenge is to avoid developing more models largely following the concept of others (‘reinventing the wheel’). The other challenge is to avoid focusing on only one type of model, while...

Match or mismatch: The influence of phenology on size-dependent life history and divergence in population structure Match or mismatch: The influence of phenology on size-dependent life history and divergence in population structure
1. In gape-limited predators, body size asymmetries determine the outcome of predator-prey interactions. Due to ontogenetic changes in body size, the intensity of intra- and interspecific interactions may change rapidly between the match situation of a predator-prey system and the mismatch situation in which competition, including competition with the prey, dominates. 2. Based on a...
