Theoretical Ecology > 2018 > 11 > 2 > 213-223

Spatially explicit approaches are widely recommended for ecosystem management. The quality of the data, such as presence/absence or habitat maps, affects the management actions recommended and is, therefore, key to management success. However, available data are often biased and incomplete. Previous studies have advanced ways to resolve data bias and missing data, but questions remain about how we...

The tangled link between β‐ and γ‐diversity: a Narcissus effect weakens statistical inferences in null model analyses of diversity patterns

Werner Ulrich, Andres Baselga, Buntarou Kusumoto, Takayuki Shiono, more

Global Ecology and Biogeography > 26 > 1 > 1 - 5

Understanding the structure of and spatial variability in the species composition of ecological communities is at the heart of biogeography. In particular, there has been recent controversy about possible latitudinal trends in compositional heterogeneity across localities (β‐diversity). A gradient in the size of the regional species pool alone can be expected to impose a parallel gradient on β‐diversity,...

Climatic and geographic correlates of global forest tree species–abundance distributions and community evenness

Werner Ulrich, Buntarou Kusumoto, Takayuki Shiono, Yasuhiro Kubota, more

Journal of Vegetation Science > 27 > 2 > 295 - 305

QuestionsSpecies–abundance distributions (SADs) have long been at the centre of ecological interest because they summarize various patterns of community assembly in condensed form. Here we link observed patterns of SAD shape and evenness to latitude and climatic conditions to infer global trends in abundance distributions. LocationGlobal. MethodsWe compiled data on tree species abundances and climate...

Yasuhiro Kubota, Buntarou Kusumoto, Takayuki Shiono, Werner Ulrich, more

Oikos > 125 > 2 > 237 - 244

The unified neutral theory of biodiversity and biogeography provides a promising framework that can be used to integrate stochastic and ecological processes operating in ecological communities. Based on a mechanistic non‐neutral model that incorporates density‐dependent mortality, we evaluated the deviation from a neutral pattern in tree species abundance distributions and explored the signatures...

Dispersal process driving subtropical forest reassembly: evidence from functional and phylogenetic analysis

Buntarou Kusumoto, Akihiro Baba, Shin-jiro Fujii, Hisakazu Fukasawa, more

Ecological Research > 2016 > 31 > 5 > 645-654

Understanding the mechanisms of secondary succession related to forest management practices is receiving increasing attention in community ecology and biodiversity conservation. Abiotic and biotic filtering are deterministic processes driving community reassembly. A functional trait or phylogeny-based approach predicts that environmental filtering induced by clearcut-logging results in functional/phylogenetic...
