Stochastic processes dominate during boreal bryophyte community assembly [PDF]

Ecology, 2013
Why are plant species found in certain locations and not in others? The study of community assembly rules has attempted to answer this question, and many studies articulate the historic dichotomy of deterministic (predictable niches) vs. stochastic (random or semi‐random processes). The study of successional sequences to determine whether they converge,

Scale decisions can reverse conclusions on community assembly processes. [PDF]

Glob Ecol Biogeogr, 2014
AbstractAimPhylogenetic diversity patterns are increasingly being used to better understand the role of ecological and evolutionary processes in community assembly. Here, we quantify how these patterns are influenced by scale choices in terms of spatial and environmental extent and organismic scales.LocationEuropean Alps.MethodsWe applied 42 sampling ...

Biotic interactions contribute more than environmental factors and geographic distance to biogeographic patterns of soil prokaryotic and fungal communities

Frontiers in Microbiology, 2023
Recent studies have shown distinct soil microbial assembly patterns across taxonomic types, habitat types and regions, but little is known about which factors play a dominant role in soil microbial communities.

Stochastic and deterministic assembly processes in subsurface microbial communities [PDF]

The ISME Journal, 2012
Abstract A major goal of microbial community ecology is to understand the forces that structure community composition. Deterministic selection by specific environmental factors is sometimes important, but in other cases stochastic or ecologically neutral processes dominate.

Four fundamental processes of community assembly [PDF]

, 2017
A central aim of ecology is understanding the mechanisms of community assembly. To address this problem, community assembly is often modeled as a sampling process, in which species are selected from a pool of available species, possibly with effects of interspecific interactions, habitat filtering, and other ecological mechanisms.

Intraspecific Trait Variation Dilutes Deterministic Processes in Community Assembly of Arid Shrubs across Multiple Scales

Diversity, 2020
Trait-based approaches present a promising avenue for improving our understanding of species coexistence and community assembly, while intraspecific trait variation (ITV) across different spatial scales is important in trait-based community assembly ...

Divergent Abiotic Stressors Drive Grassland Community Assembly of Tibet and Mongolia Plateau

Frontiers in Plant Science, 2022
Multiple ecological processes simultaneously govern community assembly, but it remains unclear how abiotic stressors regulate the relative importance of these processes among different biogeographic regions.

Contrasting archaeal and bacterial community assembly processes and the importance of rare taxa along a depth gradient in shallow coastal sediments.

Science of the Total Environment, 2022
Marine microbial communities assemble along a sediment depth gradient and are responsible for processing organic matter. Composition of the microbial community along the depth is affected by various biotic and abiotic factors, e.g., the change of redox ...

Aboveground and belowground arthropods experience different relative influences of stochastic versus deterministic community assembly processes following disturbance [PDF]

PeerJ, 2016
Background Understanding patterns of biodiversity is a longstanding challenge in ecology. Similar to other biotic groups, arthropod community structure can be shaped by deterministic and stochastic processes, with limited understanding of what moderates ...

Population Differentiation In Daphnia Alters Community Assembly In Experimental Ponds [PDF]

, 2011
Most studies of community assembly ignore how genetic differentiation within species affects their colonization and extinction. However, genetic differentiation in ecologically relevant traits may be substantial enough to alter the colonization and ...
