In this regard, several MLs (such as Support Vector Regression, SVR, and Extreme Learning Machine, ELM), two EMLs (e.g., Random Forests, RF, and Boosted Trees, BTs), as well as Gene Expression Programming (GEP), are evaluated for predicting fluorescent Dissolved Organic Matter (fDOM) in the Caloosahatchee River in Florida.

Based on the k-fold cross-validation method (<em>k</em> = 4), the applied regular MLs (SVR, ELM, and GEP) provided better performance than the traditional multiple linear regression model (on average, 6.8 % improvement in RMSE).

The outcomes of the CT model at high levels of tree pruning (PCFs = 0.01 and 0.10, and with five-time randomization effort) confirmed that an increase in the water turbidity, biological oxygen demand, electric conductivity, river depth and orthophosphate may restrict the fish's presence, while the probability of fish's presence in the river may show an increase at higher slope and flow velocity.

We have categorised the suite's 19 modules under eight distinct groups of ecosystem services.

It can be observed in this review that scientists of Chinese descent have dominated the scene by applying various modules of the InVEST model with a specific focus on assessing various issues faced by ecosystem services of specific regions related to habitats, land use, water yield, and urbanisation. Finally, we have proposed an effective solution for how other models could be coupled with InVEST to provide the scientific community a greater, more comprehensive research output.
