A flexible framework to assess patterns and drivers of beta diversity across spatial scales

Ecography, Journal Year: 2023, Volume and Issue: 2024(2)

Published: Nov. 22, 2023

The patterns and underlying ecological (e.g. environmental filtering) historical priority effects) drivers of beta diversity are scale‐dependent, but generally difficult to distinguish rarely explored with a sufficiently broad range spatial scales. We propose general scale‐explicit framework assess contrast the across hierarchical scales ranging from within fine‐scale ecoregion‐scale among broad‐scale ecoregion‐scale. By applying this aquatic macroinvertebrate datasets, we show that increases extent. With an increasing extent, shifts being more influenced by filtering recent factors (i.e. past diversity). Such effects may result variation rather than effects. also found small‐scale large‐scale act differently on extents. Our research reveals complex spatial‐scale dependence in their provides holistic understanding dynamics. represents flexible way unravel internal structure partitioning entire into scale‐specific differences have application community ecology, landscape planning biodiversity conservation.

Disentangling drivers of temporal changes in urban pond macroinvertebrate diversity

Urban Ecosystems, Journal Year: 2024, Volume and Issue: 27(4), P. 1027 - 1039

Published: Jan. 15, 2024

Abstract Ponds are key elements for ecosystem functions in urban areas. However, little is known about pond biodiversity changes over time and the drivers underlying such changes. Here, we tested whether past species assemblages, land cover environmental change influence macroinvertebrate richness temporal beta diversity. We also compared spatial diversity, investigated species-specific colonization extinction rates time. sampled presence of Odonata Trichoptera (larvae), Coleoptera Hemiptera (larvae adults) 30 ponds Stockholm, Sweden, 2014 2019. Past was best predictor current richness, whereas environment were not significantly related to richness. No correlations between diversity or detected. showed large their with equal contributions from gains losses. The probability colonizing going extinct revealed that more common likely colonize a pond, while uncommon go pond. Within our 5-year study, found (i) highly similar (ii) good richness; however, same does hold true composition. high dynamics communities suggest number required maintain at landscape level.

Temporal Alpha and Beta Diversity of Diving Beetles (Coleoptera: Dytiscidae) Reveals Biotic Heterogenisation in Urban Ponds

Freshwater Biology, Journal Year: 2024, Volume and Issue: 70(1)

Published: Dec. 24, 2024

ABSTRACT Urbanisation has led to decreasing quantity and quality of both terrestrial aquatic habitats, resulting in biodiversity loss urban ecosystems. Current research focused on spatial patterns along gradients, while temporal have received little attention. Here, we investigated how alpha beta diversity beetles changed through time, if pond structural connectivity (i.e., clustering the ponds) presence or absence fish affected change. We trapped diving (Dytiscidae) 20 ponds Helsinki Metropolitan Area, Finland, for six years analysed data using generalised linear mixed models index. found that (a) dytiscid diversity, i.e., species richness total abundances, decreased increased. (b) Clustered had higher than isolated ponds, but did not differ between clustered ponds; lower losses gains ponds. (c) Ponds with change during study period, without experienced declining over time; fish. Our results indicate assemblages biotic heterogenisation years, processes are different Dytiscids more likely maintain stable populations due immigration via rescue effects long‐lasting negative may replace urban‐sensitive urban‐adapted species. The dynamics invertebrates suggest improving landscape local habitat conditions can mitigate support communities

Beetle mania: Understanding pond aquatic beetles diversity patterns through a multiple-facet approach

Heliyon, Journal Year: 2023, Volume and Issue: 9(9), P. e19666 - e19666

Published: Aug. 30, 2023

Ecological studies searching for drivers of biodiversity variation have frequently focused on taxonomic richness. However, more aspects biodiversity, namely diversity facets can be considered to properly assess biotic-environment relationships. Here, we explore the environmental factors that could control four aquatic Coleoptera from 93 regionally sampled Patagonian ponds. We also which are ponds with high values all prioritize them a conservation value. fitted generalized additive models (GAM) test relationships among environment (i.e., local and climatic variables) beetles richness (SD), functional (FD), phylogenetic (PD), contribution beta (LCBD). Climatic were most important predictors beetle facets, exhibited linear nonlinear responses. Thus, warmer Patagonia highest SD PD, whereas LCBD peaked colder sites suggesting under extreme temperatures sustain unique assemblages. Moreover, located in areas higher precipitation variability exhibit assemblages). This result addition arid conditions prevailing since 16 m.y.a made us think pond-dwellers basally adapted aridity. calculated an index summarizes patterns, assign value those values. The relative importance each facet varies pond pond. Hence, this multifaceteded approach not only allows identify priority but focuses including multiple understand spatial patterns.

Although freshwater habitats, especially springs, are widely recognized as top-priority habitats for monitoring and conservation procedures, their fauna, water beetles, still poorly studied in the southeastern part of Europe. Thus, dominant beetle these E. bosnica (Zaitzev, 1908) (Insecta: Coleoptera: Elmidae), has been completely ignored misidentified. This study represents first review its taxonomy population ecological traits. Both published unpublished data presented discussed, well results field sampling 46 springs other waterbodies conducted this region from 2004 to 2019.
