Urban biotic homogenization: Approaches and knowledge gaps
Ecological Applications, Volume 32, Issue 8, December 2022., 2022 Abstract Urbanization is restructuring ecosystems at an unprecedented pace, with complex and profound consequences for life on Earth. One of the hypothesized trajectories of urban ecosystems and species communities is biotic homogenization, possibly leading to very similar species assemblages in cities across the globe.

RAMario: Experimental Approach to Reptile Algorithm -- Reinforcement Learning for Mario [PDF]
arXiv, 2023 This research paper presents an experimental approach to using the Reptile algorithm for reinforcement learning to train a neural network to play Super Mario Bros. We implement the Reptile algorithm using the Super Mario Bros Gym library and TensorFlow in Python, creating a neural network model with a single convolutional layer, a flatten layer, and a ...

Local biodiversity change reflects interactions among changing abundance, evenness, and richness
Ecology, Volume 103, Issue 12, December 2022., 2022 Abstract Biodiversity metrics often integrate data on the presence and abundance of multiple species. Yet our understanding of covariation between changes to the numbers of individuals, the evenness of species relative abundances, and the total number of species remains limited.

Sequential spatially balanced sampling
Environmetrics, Volume 33, Issue 8, December 2022., 2022 Abstract Sequential sampling occurs when an entire population is unknown in advance and data are received one by one or in groups of units. This article proposes a new algorithm to sequentially select a balanced sample. The algorithm respects equal and unequal inclusion probabilities. The method can also be used to select a spatially balanced sample if
