After much debate, there is an emerging consensus that the composition of many ecological communities is determined both by species traits, as proposed by niche theory, as well as by chance events. A critical question for ecology is, therefore, which attributes of species predict the dominance of deterministic or stochastic processes. We outline two hypotheses by which organism size could determine which processes structure ecological communities, and we test these hypotheses by comparing the… 
Abiotic and biotic factors creating variation among bromeliad communities
TLDR
This thesis combined observational and experimental approaches to quantify deterministic processes within a particular ecological community – they phytotelmata of bromeliad plants to examine ecological determinism on a smaller scale.
Organism body size structures the soil microbial and nematode community assembly at a continental and global scale
TLDR
This study elucidates a significant and consistent relationship between an organism life-history trait and how distinct ecological processes operate in mediating their respective community assemblages, thus providing a better understanding of the mechanisms supporting soil biodiversity.
Ecological determinants of community structure across the trophic levels of freshwater food webs: a test using bromeliad phytotelmata
TLDR
If biotic forces are at least as important as the abiotic forces while the importance of stochasticity declines towards upper trophic levels, then troPHic levels could respond differently to natural or anthropogenic disturbance and to shifts in species distributions.
Resources Alter the Structure and Increase Stochasticity in Bromeliad Microfauna Communities
TLDR
The results demonstrate that bromeliad microfauna communities are strongly controlled by bottom-up forces and suggest that the relative importance of stochasticity may change with productivity and with the organizational level at which communities are examined.
How planktonic microcrustaceans respond to environment and affect ecosystem: a functional trait perspective
TLDR
The objective was to review the literature on linking functional traits to environmental drivers and ecosystem processes for planktonic cladocerans and copepod and point out the need of more functional trait research, especially with freshwater copepods and neglected tropical species.
Contrasting the relative importance of species sorting and dispersal limitation in shaping marine bacterial versus protist communities
TLDR
The analyses indicated that protist communities were governed more strongly by species sorting relative to dispersal limitation than were bacterial communities; this pattern was consistent across the three-depth layers, albeit to different degrees, and supported the ‘size-plasticity’ hypothesis.
Dispersal Ability Determines the Role of Environmental, Spatial and Temporal Drivers of Metacommunity Structure
TLDR
The results supported the view that “all-or- nothing” interpretations on the mechanisms structuring metacommunities are rather the exception than the rule and emphasize the strength of a trait-based analysis and of better defining spatial variables.
Both species sorting and neutral processes drive assembly of bacterial communities in aquatic microcosms.
TLDR
Evidence is provided for both processes being important during the colonisation of aquatic environments and a novel way to apply the neutral model is presented.
Stochastic distribution of small soil eukaryotes resulting from high dispersal and drift in a local environment
TLDR
A random distribution of soil eukaryotes with respect to space and environment in the absence of environmental gradients at the local scale is indicated, reflecting the dominant role of drift and homogenizing dispersal.

Niches versus neutrality: uncovering the drivers of diversity in a species-rich community.
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.
Niche partitioning at multiple scales facilitates coexistence among mosquito larvae
TLDR
In this community, a niche-based mechanism that is predicted to stabilize species coexistence explains co-occurrence patterns within and among bromeliads and there is no evidence to support neutral dynamics in mosquito communities at either scale.
The role of environmental and spatial processes in structuring lake communities from bacteria to fish.
TLDR
The results suggest that crustacean zooplankton and fish are more constrained by dispersal and therefore more likely to operate as a metacommunity than are bacteria and phytoplankon within this studied landscape.
THE CO‐DISTRIBUTION OF SPECIES IN RELATION TO THE NEUTRAL THEORY OF COMMUNITY ECOLOGY
TLDR
Two systematic surveys of plant communities do indeed show stronger associations than are expected in randomly assembled communities, but neutral community models, however, also predict nonrandom patterns of co-distribution.
Spatial autocorrelation and dispersal limitation in freshwater organisms
TLDR
The data suggest that the critical threshold where greater body size increases dispersal limitation seems to come at the juncture between invertebrates and vertebrates rather than that between unicellular and multicellular organisms as has been previously suggested.
Weak coupling between community composition and functioning of aquatic bacteria
TLDR
Bacteria originating from a slightly acidic polyhumic lake failed to grow, grew unsteadily, or exhibited an extended lag phase when exposed to media originating from other lakes, indicating that the bacterial community in the polyhumics was not able to adapt rapidly to changes in environmental conditions.
Dormancy contributes to the maintenance of microbial diversity
TLDR
A theoretical model demonstrating that microbial communities are structured by environmental cues that trigger dormancy is developed and it is proposed that repeated transitions to and from the seed bank may help maintain the high levels of microbial biodiversity that are observed in nearly all ecosystems.
Habitat isolation moderates the strength of top-down control in experimental pond food webs.
TLDR
The results from an experiment performed in artificial ponds manipulating habitat isolation crossed with a predator reduction treatment showed that habitat isolation can alter the structure of communities by a combination of direct effects of the species in question, as well as effects mediated through their interactions in the food web.
Regional invariance among microbial communities.
TLDR
It is proposed that the degree of regional invariance can be linked to the evolution of microbes and the variation in ecosystem functions performed by microbial communities.
Evaluating the long-term metacommunity dynamics of tree hole mosquitoes.
TLDR
The results did not match a single model and therefore caution against overly simplifying metacommunity dynamics by using one dynamical characteristic to select a particular metACommunity perspective.
