Implementation of the EPA's Ecological Exposure Research Division (EERD) tools (discontinued in 1999) for Probit and Trimmed Spearman-Karber Analysis.
    Probit and Spearman-Karber methods from Finney's book "Probit analysis a statistical treatment of the sigmoid response curve" with options for most accurate results or identical results to the book.
    Probit and all the tables from Finney's book (code-generated, not copied) with the generating functions included.
    Control correction: Abbott, Schneider-Orelli, Henderson-Tilton, Sun-Shepard.
    Toxicity scales: Horsfall-Barratt, Archer, Gauhl-Stover, Fullerton-Olsen, etc.

The US EPA ECOTOX database is a freely available database
    with a treasure of aquatic and terrestrial ecotoxicological data.
    As the online search interface doesn't come with an API, this
    package provides the means to easily access and search the database
    in R. To this end, all raw tables are downloaded from the EPA website
    and stored in a local SQLite database <doi:10.1016/j.chemosphere.2024.143078>.

Analysis of temporal changes (i.e. dynamics) of ecological entities, defined as trajectories on a chosen multivariate space, by providing a set of 
    trajectory metrics and visual representations [De Caceres et al. (2019) <doi:10.1002/ecm.1350>; 
    and Sturbois et al. (2021) <doi:10.1016/j.ecolmodel.2020.109400>]. Includes functions
    to estimate metrics for individual trajectories (length, directionality, angles, ...) as well as
    metrics to relate pairs of trajectories (dissimilarity and convergence). Functions are also
    provided to estimate the ecological quality of ecosystem with respect to reference conditions 
    [Sturbois et al. (2023)  <doi:10.1002/ecs2.4726>].

Computes temporal trends in environmental suitability obtained from ecological niche models, based on a set of species presence point coordinates and predictor variables.

An approach and software for modelling marine and freshwater ecosystems. It is articulated entirely around trophic levels. EcoTroph's key displays are bivariate plots, with trophic levels as the abscissa, and biomass flows or related quantities as ordinates. Thus, trophic ecosystem functioning can be modelled as a continuous flow of biomass surging up the food web, from lower to higher trophic levels, due to predation and ontogenic processes. Such an approach, wherein species as such disappear, may be viewed as the ultimate stage in the use of the trophic level metric for ecosystem modelling, providing a simplified but potentially useful caricature of ecosystem functioning and impacts of fishing. This version contains catch trophic spectrum analysis (CTSA) function and corrected versions of the mf.diagnosis and create.ETmain functions.
