The Ensemble of Small Models (ESM) is a method proposed by Lomba et al. 2010 and Breiner et al. 2015 to address the challenges associated with modeling the spatial distributions of rare or poorly known species. This approach is particularly useful when occurrence data for these species are limited, which can lead to model overfitting…
The white-backed vulture (Gyps africanus) is critically endangered, facing rapid population declines due to anthropogenic threats like poisoning, drowning, and collisions with energy infrastructure. To aid conservation efforts, this case study focuses on modeling the distribution of the white-backed vulture in Kruger National Park, South Africa. We aim to highlight environmental variable that guide G….
In the post-modeling part, you will learn how to predict, evaluate, and correct species distribution models. In modeling section, we have fitted three categories of models – Ensemble of Small Models (ESM), Standards models and Ensemble models. Prediction When you fit ESM with more than one algorithm, the prediction, will be done manually selecting the…
This section covers modeling completing data query part and pre-modeling. We will reach out models fitting and ensembling Model fitting Model fitting is the ability we give to a machine to generalize data on which the model is trained. In practice, it consists of provide training data and some parameters to models in a way…
The pre-modeling step in species distribution modeling refers to the preparatory phase before constructing the actual model. It involves a series of tasks aimed at gathering and preparing the necessary data, as well as conducting exploratory analyses to ensure the data is suitable for modeling. Let’s move to pre-modeling in nimo that contains five main…
In this support section, we will walk around the features available in nimo to query occurrence data. If the package is no yet installed, follow the get starting page to install. GBIF Interface The GBIF Interface presents three tabs; Query, Occurrence and Citation. In this tab, you can browse globe as you need to query…
