“…In this sense, there exist membrane computing models on population dynamics that use a membrane graph to represent space [13,18,21]. However, the usage of a membrane graph to represent a lattice of spatial regions is not common in the literature of membrane computing models in population dynamics, even though it is a widespread practice in agent-based modeling in fisheries [5,12,37,38]. In this sense, we plan to apply membrane computing as a modeling framework for spatially-explicit phenomena in population dynamics in aquatic ecosystems, using membrane grids to represent spatial and other types of regions.…”

Diel vertical migration (DVM) is an important ecological phenomenon in which zooplankton migrate vertically to deal with trade-offs associated with greater food availability in shallow waters and lower predator risk in deep waters due to lower light availability. Because of these trade-offs, DVM dynamics are particularly sensitive to changes in light intensity at the water surface. Therefore, changes in the proportion of cloudy and sunny days have the potential to disrupt DVM dynamics. We propose a new membrane computing model that captures the effect of cloud cover on DVM in Daphnia, and we use it to explore the impacts of an increased proportion of cloudy days that are predicted to occur with climate change. Our 2-dimensional, spatially explicit model integrates multiple trophic levels from abiotic nutrients to Daphnia predators. We analyzed the effect that different proportions of cloudy and sunny days throughout the summer have on our model. The model simulations suggest that an increase in sunny days promotes a high phytoplankton concentration near the surface but does not necessarily promote an increased abundance of Daphnia. Our model also suggests that a higher proportion of cloudy days would increase Daphnia abundance due to a shift in the vertical distribution of Daphnia populations towards superficial waters. Our results highlight that climate changes in multiple regions will affect animal migrations leading to altered food web dynamics in freshwater ecosystems, and emphasize the potential of membrane computing as a modeling framework for spatially and temporally explicit ecological processes.

“…Traditional growth models often oversimplified the complex processes underlying fish growth. However, contemporary approaches, such as individual-based models (e.g., [18]) and bioenergetics models (e.g., [19]), account for the intricate interplay between biological, environmental, and ecological factors. These innovative models integrate environmental factors to create more accurate representations of growth trajectories [20].…”
