Package AquaEnv: an Aquatic modelling Environment in R
نویسندگان
چکیده
AquaEnv (Hofmann et al. 2010b) is an integrated development toolbox for aquatic chemical model generation focused on (ocean) acidification and CO2 air-water exchange. It contains ❼ All elements necessary to model the pH, the related CO2 air-water exchange, as well as aquatic acid-base chemistry in general for an arbitrary marine, estuarine or freshwater system. ❼ A suite of tools to visualize this information. ❼ It can be used to build dynamic models of aquatic systems that include acid-base chemistry. ❼ The sensitivity of the system to variations in the input variables can be visualized. ❼ A number of example “applications” that make use of AquaEnv are: – a theoretical titration simulator – a routine to determine total alkalinity ([TA]), the total dissolved inorganic carbon concentration ([ ∑ CO2]), as well as additionally the electrode standard potential (E0) and the first dissociation constant of the carbonate system (K ∗ CO2 ) from titration data.

An Introduction to the EcoTroph R Package: Analyzing Aquatic Ecosystem Trophic Networks
Recent advances in aquatic ecosystem modelling have particularly focused on trophic network analysis through trophodynamic models. We present here a R package devoted to a recently developed model, EcoTroph. This model enables the analysis of aquatic ecological networks and the related impacts of fisheries. It was available through a plug-in in the well-known Ecopath with Ecosim software or thr...
متن کاملThe phenotypic plasticity of the aquatic invertebrate Caenis latipennis in response to environmental conditions in the Kheirood Kenar River, Iran
Phenotypic plasticity is the capability of an organism to change its shape in response to the environmental condition. The present study aimed to investigate the phenotypic plasticity of the aquatic invertebrate Caenis latipennis using outline analysis. Samples were collected from up- and downstream of the Kheirood Kenar River, identified to the species level and photographed using a digital ca...

BACKGROUND Predictive regression models can be created with many different modelling approaches. Choices need to be made for data set splitting, cross-validation methods, specific regression parameters and best model criteria, as they all affect the accuracy and efficiency of the produced predictive models, and therefore, raising model reproducibility and comparison issues. Cheminformatics and ...
متن کاملmizer: an R package for multispecies, trait-based and community size spectrum ecological modelling
Size spectrum ecological models are representations of a community of individuals which grow and change trophic level. A key emergent feature of these models is the size spectrum; the total abundance of all individuals that scales negatively with size. The models we focus on are designed to capture fish community dynamics useful for assessing the community impacts of fishing.We present mizer, a...
