Linkage between community assemblage of floral traits and pollinator fauna: a comparison among six geographical regions

Plant Biology, Journal Year: 2025, Volume and Issue: unknown

Published: April 1, 2025

Abstract The persistence of angiosperm communities largely depends on pollinator‐mediated interactions. However, the importance plant–pollinator interactions has often been overlooked in studies plant community assembly. This study aims to assess influence assembly communities. We compared distribution three floral traits (colour, symmetry, and tube length) across approximately 650 animal‐pollinated species six located distinct geographical regions: Mongolian grassland, Japanese alpine zone, Swedish subalpine New Zealand zone. Additionally, we examined pollinator fauna each community, focusing taxon‐specific usage by pollinators. composition all was predictably linked taxonomic preferences pollinators for certain traits. Furthermore, dispersion morphology fauna, rather than phylogenetic Interestingly, while flower symmetry family composition, compositions colour length were almost independent composition.

Abstract Aim Understanding the patterns and drivers of biodiversity across space time is commonly based on species diversity, which may ignore species' functional role evolutionary history result in an incomplete understanding community assembly. It suggested that integrating species, functional, phylogenetic diversity could provide a more holistic assessment assembly natural ecosystems.

Patterns of Tadpole β Diversity in Temperate Montane Streams

Animals, Journal Year: 2024, Volume and Issue: 14(8), P. 1240 - 1240

Published: April 20, 2024

Understanding the spatial variation and formation mechanism of biological diversity is a hot topic in ecological studies. Comparing with α diversity, β more accurate reflecting community dynamics. During past decades, studies usually focused on plants, mammals, birds. Studies amphibian montane ecosystems, particular, tadpoles, are still rare. In this study, Mount Emei, located southwestern China, was selected as study area. We explored tadpole 18 streams, based two-year survey (2018–2019). Our results indicated high total assemblages, which determined by both turnover nestedness processes, dominant component turnover. Both were significantly positively correlated geographical, elevational, environmental distances, but no significant relationship detected between these component. Moreover, independent contributions river width, current velocity, chlorophyll larger than that geographical elevational distance. Overall, factors, while contribution factors larger. Future can focus functional phylogenetic structures, to better understand assembly process.

Biological diversity is a concept that contains multiple facets, of which functional considered to be more integrative describe the relationship between biodiversity and ecosystem functioning. In recent decades, patterns have been assessed along elevational gradients in plants birds. However, few empirical studies conducted reveal amphibian zonations on mountains. present study, we investigated ecomorphologically different Nepal Himalaya. Our results indicated space occupied by assemblages differed size zonations, with zonation-2 (500–1300 m) occupying highest proportion. terms position space, low (zonation 1 & 2) significantly from those high 3–5).

Interestingly, despite morphologically extreme amphibians accounted for small proportions total number amphibians, they filled large proportion dimensional space. More importantly, were also uniqueness individuals, widely distributed all zonations. Therefore, vulnerability exists throughout Accordingly, should particular well protected maintain diversity.

Abstract Land use changes are considered a significant cause of amphibian declines worldwide. However, little is known regarding which land uses have more pervasive impacts and help to supplement the biodiversity conserved in protected areas. In addition, species respond broad array geographical constraints, may blur responses disturbance, depending on species' natural history. Here, we explored whether functional diversity patterns assemblages linked human while considering spatial autocorrelation phylogenetic relatedness among species. We surveyed tadpoles along 500 km coastal wetlands southern Brazil quantified four traits related tadpole habitat predator avoidance. Spatial components influenced richness greater extent than use. Functional evenness was higher ponds surrounded by exotic reforestation, lesser an effect crop area. divergence also associated with reforestation Our results showed that some (reforestation temporary crops) communities. Such communities occurred even at low levels landscape change. findings highlight conversion requires complementary approaches (i.e., adult responses) provide early warning signals about modification effects.
