Spatial and temporal scale of analysis alter conclusions about the effects of urbanisation on plant–pollinator networks

Abstract Bipartite networks of flowering plants and their visitors (potential pollinators) are increasingly being used in studies the structure function these ecological interactions. Whilst they hold much promise understanding ecology plant–pollinator how this may be altered by environmental perturbations, like land-use change invasive species, there is no consensus about scale at which such should constructed analysed. Ecologists, however, have emphasised that many processes dependent. Here, we compare network- species-level properties analysed level a site, pooling across sites within given habitat for each month surveys, all months to create single network per type. We additionally considered three scales resolution influenced conclusions regarding differences between according two contrasting types (urban bushland remnants residential gardens) influence honey bee abundance on properties. found most varied markedly depending analysis, as did significance, or lack thereof, type caution against can unrealistic links, invalidating structure. In conclusion, consideration analysis also important when conducting interpreting networks.

Global change and plant–pollinator communities in Mediterranean biomes

Global Ecology and Biogeography, Journal Year: 2023, Volume and Issue: 32(11), P. 1893 - 1913

Abstract Aim Occurring in five distinct global regions, Mediterranean‐type ecosystems (MTEs) include both centres of agricultural production and hotspots extratropical biodiversity – particularly for plants bees. Considerable research has addressed the persistence highly diverse biological communities within MTEs, despite their typically long histories anthropogenic natural disturbance. However, important questions remain, especially regarding limits ecological resilience face accelerating environmental change. Here, we explore current knowledge effects disturbance on MTE plant–pollinator communities. Location Mediterranean Basin, California, Cape Province South Africa, Central Chile Southern South‐Western Australia. Taxa Studied Flowering pollinators (insects, birds mammals). Methods We reviewed available literature about via a systematic search that yielded 234 case studies. analysed this dataset to quantify efforts across regions taxonomic groups, proportion surveys addressing interactions (i.e. rather than only diversity) availability work community responses specific stressors (viz. climate change, landscape alteration, fire, farming, grazing, urbanization species introductions). Results Current is dominated by from northern while Hemisphere California are markedly understudied comparison. Taxonomic coverage similarly uneven, with 58% studies focusing single pollinator group. Furthermore, less half address networks. Finally, some pioneering introductions, 13% focus impact interaction Outlook Based our findings, identify need coordinated international (i) community‐level studies, observational experimental, (ii) networks, (iii) functional traits mediating post‐disturbance recovery (iv) impacts combined/synergistic stressors. Progress these areas will facilitate predictions long‐term change

Plant–hummingbird interaction networks in an urban area: a generalist species as the protagonist in mutualistic and agonistic interactions

Studies on Neotropical Fauna and Environment, Journal Year: 2024, Volume and Issue: unknown, P. 1 - 11

Published: April 22, 2024

The maintenance of green areas within cities is essential for promoting urban biodiversity and species interactions. Here, we evaluated the interactions between hummingbirds their visited plants over course a year in an park Barreiras, western Bahia, Brazil. Each month, from October 2018 to September 2019, recorded hummingbird species, they visit, agonistic We 748 legitimate visits by six five plant species. Most (60%) flowered continuously, most were rainy season when network was also more specialized (H2' = 0.821). Chionomesa fimbriata only during all studied months. This performed 70% involved (n 68). availability resources affected number (p 0.016). Tree producing many flowers increased diversity concentrated Plant with continuous flowering represented persistent supply resources, favoring residence C. study site. Despite low richness attests importance maintaining spaces promote biodiversity.
