Abundance distributions for tree species in Great Britain: A two‐stage approach to modeling abundance using species distribution modeling and random forest
High-quality abundance data are expensive and time-consuming to collect and often highly limited in availability. Nonetheless, accurate, high-resolution abundance distributions are essential for many ecological applications ranging from species conservation to epidemiology. Producing models that can predict abundance well, with good resolution over large areas, has therefore been an important a...
متن کاملSpecies abundance distributions over time.
It has been known for 50 years that the time period over which data are collected affects the shape of empirical species abundance distributions. However, despite a recent resurgence of interest in characterizing and explaining these patterns the temporal component of species abundance distributions has been largely ignored. I argue that it is essential to take account of time, and not only bec...
متن کاملSpecies abundance distribution and dynamics in two locally coupled communities.
This study considered a model for species abundance dynamics in two local community (or islands) connected to a regional metacommunity. The model was analyzed using continuous probabilistic technique that employs Kolmogorov-Fokker-Planck forward equation to derive the probability density of the species abundance in the two local communities. Using this technique, we proposed a classification fo...
متن کاملModeling Joint Abundance of Multiple Species Using Dirichlet Process Random Effects
We present a method for modeling multiple species distributions simultaneously using Dirich1 let Process random effects to cluster species into guilds. Guilds are ecological groups of 2 species that behave or react similarly to some environmental conditions. By modeling latent 3 guild structure, we capture the cross-correlations in abundance or occurrence of species over 4 surveys. In addition,...
متن کاملTaking species abundance distributions beyond individuals.
The species abundance distribution (SAD) is one of the few universal patterns in ecology. Research on this fundamental distribution has primarily focused on the study of numerical counts, irrespective of the traits of individuals. Here we show that considering a set of Generalized Species Abundance Distributions (GSADs) encompassing several abundance measures, such as numerical abundance, bioma...
