TLDR
This work provides the first empirical evidence that a niche-neutral model can explain niche space occupancy pattern in a natural species-rich community and suggests this class of model may be a useful hypothesis for the generation and maintenance of species diversity in other size-structured communities.Abstract:
Ecological models suggest that high diversity can be generated by purely niche-based, purely neutral or by a mixture of niche-based and neutral ecological processes. Here, we compare the degree to which four contrasting hypotheses for coexistence, ranging from niche-based to neutral, explain species richness along a body mass niche axis. We derive predictions from these hypotheses and confront them with species body-mass patterns in a highly sampled marine phytoplankton community. We find that these patterns are consistent only with a mechanism that combines niche and neutral processes, such as the emergent neutrality mechanism. In this work, we provide the first empirical evidence that a niche-neutral model can explain niche space occupancy pattern in a natural species-rich community. We suggest this class of model may be a useful hypothesis for the generation and maintenance of species diversity in other size-structured communities.read more

Dietary niche differentiation in a mesopredatory dasyatid assemblage
TL;DR: Investigation of trophic niches of a resident assemblage of dasyatids at St. Joseph Atoll showed that all juveniles were reliant upon the same carbon resources at the base of the food web, and diet appeared to change with size as larger individuals displayed lower stomach contents and higher isotope values, suggesting maternal meddling.

TL;DR: The results suggest that species within clumps behave in a quasi-neutral state, but even minor shifts in trait composition may affect species biovolume.

Generalized Additive Models: An Introduction with R, Second Edition
TL;DR: In this article, a simple linear model is proposed to describe the geometry of linear models, and a general linear model specification in R is presented. But the theory of linear model theory is not discussed.

The Unified Neutral Theory of Biodiversity and Biogeography
TL;DR: A study of the issue indicates that it is not a serious problem for neutral theory, and there is sometimes a difference between some of the simulation-based results of Hubbell and the analytical results of Volkov et al. (2003).

Mechanisms of Maintenance of Species Diversity
TL;DR: Stabilizing mechanisms are essential for species coexistence and include traditional mechanisms such as resource partitioning and frequency-dependent predation, as well as mechanisms that depend on fluctuations in population densities and environmental factors in space and time.

TL;DR: By emphasizing the very aspects that might result in their denial of them were they less plain the authors can keep the principle explicitly present in their minds untit they see if its implications are, or are noty as unpleasant as their subconscious might suppose.

The Paradox of the Plankton
TL;DR: The problem that is presented by the phytoplankton is essentially how it is possible for a number of species to coexist in a relatively isotropic or unstructured environment all competing for the same sorts of materials.
