Abstract An understanding of the relative importance ecological processes affecting biological communities can assist in interpretations biodiversity patterns. However, mechanism behind temporal beta diversity, which refers to dissimilarity between community structures at different times, remains unclear for aquatic insect communities. Therefore, we collected monthly samples insects five sites streams from July 2011 June 2012 Central China. The sample were located river sections with perennially flowing water, subject little human disturbance. We examined taxonomic‐ and trait‐based diversity patterns riverine across seasons sites. Taxonomic‐ demonstrated a decline species richness but an increase time sampling dates. Taxonomic‐based was significantly higher than diversity. Turnover (i.e. replacement) main driver taxonomic‐based whereas nestedness gain or loss) contributed more beta‐diversity values. In addition, correlation weak. Deterministic operating through physico‐chemical factors climate) stochastic variables) are distinct, they act together influencing insects. sensitive environmental changes taxonomic shift do not necessarily result trait changes. changed location components analysed. contrast, most dominant influence on Results suggest that conservation measures should consider both turnover protection China elsewhere. Additionally, development integrated monitoring management protocols apply life stages be considered.

Understanding how and why assemblage dissimilarity changes along spatial gradient is a great challenge in ecology, because answers to these questions depend on the analytical types, dimensions, components of beta diversity we concerned. To obtain comprehensive understanding its implications for biodiversity conservation Himalayas, explored elevational patterns determinants turnover nestedness pairwise multiple types taxonomic phylogenetic dimensions simultaneously. Patterns their different were calculated based 96 sampling quadrats an 1800−5400 m gradient. We examined whether differed from random expectations using null models. Furthermore, used forest methods quantify role environmental variables representing climate, topography, human disturbance determining patterns. found that component, regardless shown hump-shaped Both remarkably lower than counterpart. These significantly less expectation mostly associated with climate variables. In summary, our results suggested seed plants was originate replacement closely related species determined by climate-driven filtering. Accordingly, efforts should better cover elevations maximalize conservation, rather only focus highest richness. Our study demonstrated comparisons could be conductive consensus origin mechanism dissimilarity.

Biotic Interactions Shape Soil Bacterial Beta Diversity Patterns along an Altitudinal Gradient during Invasion

Microorganisms, Год журнала: 2024, Номер 12(10), С. 1972 - 1972

Опубликована: Сен. 28, 2024

Invasive plants have already been observed in the understory of mountain forests, which are often considered a safe shelter for most native plants. Microorganisms might be drivers plant invasions. Nevertheless, mechanisms determining variations microbial community composition (beta diversity) during invasion along altitudinal gradients remain to elucidated. Here, elevational patterns and driving ecological processes (e.g., environmental filtering, co-occurrence patterns, assembly processes) soil bacterial beta diversity were compared between invasive on Qinling Mountains. The species turnover dominated compositional dissimilarities both communities, its contribution total decreased invasion. Total exhibited significant binominal over an gradient, with tipping point 1413 m. Further analysis showed that contributions parallel increase process, indicating interdependence rather than niche partitioning is strongly correlated biogeography communities. Plant affects relative stochastic interactions through regulation physiochemical characteristics soil, ultimately determines components gradients.
