The degree of urbanisation reduces wild bee and butterfly diversity and alters the patterns of flower-visitation in urban dry grasslands

Scientific Reports, Journal Year: 2023, Volume and Issue: 13(1)

Published: Feb. 15, 2023

Abstract Insect-provided pollination services are increasingly threatened due to alarming declines in insect pollinator populations. One of the main threats pollinators and consequently is urbanisation. Here, we investigate effects local habitat quality (patch size, flowering plant richness, bare soil cover, vegetation structure), degree urbanisation (impervious surfaces) 3D connectivity on bee, hoverfly butterfly flower visitors plant-flower visitor networks flower-rich urban dry grasslands. Overall, influenced communities. Although abundance increased with urbanisation, bee species richness decreased increasing impervious surfaces. Flowering ground nesting resource availability were positively related structure boosted visitation rates. In terms plant–pollinator interactions, visited a lower proportion available plants more urbanised areas network modularity specialisation patch size. Our findings show that grasslands valuable habitats for species-rich communities further highlight importance minimizing intensity potential management practices support biodiversity cities.

Abstract Predicting how habitat composition alters communities of mobile ecosystem service providers remains a major challenge in community ecology. This is partially because separate taxonomic groups that provide the same may respond uniquely to changes and associated resource availability. Further, spatial scale at which features impact each group can vary. Failure account for these differences significantly limits ability quantify shared versus contrasting responses important service‐providing groups. We investigated impacts local (habitat patch level) landscape US Southern Great Plains on pollinating insects with different basic biologies: Coleoptera, Diptera, Hymenoptera Lepidoptera. Habitat included flower shelter resources as well landscape‐scale semi‐natural habitat. found bare ground supported more Lepidoptera but fewer while diverse Coleoptera. Interestingly, given this study occurred grassland system, forest cover surrounding strongly affected pollinator diversity than did. Landscapes woodland had higher Coleoptera Diptera richness. Our results highlight conservation sustainable land management depend understanding needs, including shelter, pollinators. Because taxa have opposite specific or scales, providing range practices (e.g., variety timing type biomass removal) be most effective approach support broader community.

The adverse effects of urbanized areas’ growth might be mitigated by the multiple ecosystem services that urban green infrastructure provides. However, design and composition such is still a hotly debated issue, mainly considering challenges associated with use exotic plant species. To assess if there clear association between species’ origin or disservices, an in-depth systematic literature review was carried out based on bibliometric approach to panorama scientific perspective. Based results, detailed analysis performed for five European Mediterranean cities, where management expansion act as tools mitigate climate change biodiversity loss. Urban benefits areas its must consider balance disservices provided Data shows are not exclusively related species, revealing species selection their represents biased approach, it often disregards higher capacity some thrive under continuous pressure disturbance, along relevant highly valued cultural provided.

University campuses, as small and isolated areas of rapidly growing urban areas, can provide a unique opportunity for biodiversity research, conservation, education, citizen science by monitoring assemblages butterflies within their areas. We surveyed butterfly in developing area represented the Chenggong Campus Yunnan southwestern China using Pollard walk method. In total, 3625 individuals belonging to 50 species, 35 genera, six families were recorded this survey. The results showed that Pieridae Nymphalidae are with highest species richness on campus, family Riodinidae contained fewest species. Pieris rapae was most common seven assessed IUCN Red List recorded. Butterfly community structure varied across habitats seasons diversity higher spring autumn than it summer winter, well being road scenic habitats. Unavoidable urbanisation activities (construction, green space planning, etc.) may have influenced composition butterflies, conserving requires balance between planning habitat diversity. Finally, we encourage universities research institutions develop platforms scientists participate in.

Abstract. Pasaribu DN, Rizali A, Tarno H, Priawandiputra W, Johannis M, Buchori D. 2024. Agricultural landscape composition alters ant communities in maize fields more than plant diversity enrichment. Biodiversitas 25: 205-213. Fragmented natural habitats human-modified landscapes play a crucial role conserving biodiversity. Ants, as keystone species, are integral to terrestrial ecosystems, making it essential comprehend the factors influencing their survival. This study investigates impact of agricultural and enrichment (flowering plants) management on shaping (Zea mays L.) fields. The research occurred surrounded by other crops, semi-natural habitats, housing areas Malang District, East Java, Indonesia. four were divided into control treatment plots, considering parameters, particularly Class Area (CA) Number Patches (NP), measured within 500 m radius. around was characterized manually digitizing land use. Six types employed this study: wild cosmos (Cosmos caudatus), white buttercup (Turnera subulata), sunflower (Helianthus annuus), long bean (Vigna unguiculata), ornamental (Arachis pintoi), coral vine (Antigonon leptopus). dry season (April-July 2022) wet (September-December 2022). Ant sampling conducted using pitfall traps and, based generalized linear models, revealed that did not affect species richness, abundance, or ants. Landscape positively influenced richness but negatively impacted composition, number habitat patches. Maize crop age also affected beta diversity. Wet found have negative effect In conclusion, proportion contribute significantly

The commercial stingless bee Heterotrigona itama naturally nests in tree cavities but was kept wooden boxes meliponiculture farms. However, at Universiti Malaysia Sabah (UMS), these bees primarily nest lamp posts. We conducted a temperature survey to assess posts as potential nesting sites for H. itama, aiming determine if the preference occupied related their distribution. measured ambient temperatures shaded areas and unoccupied exposed on UMS campus, calculating percentage of time fell outside optimal range itama. Additionally, we analyzed occurrence timing regulation post by comparing differences between across four-time blocks. Temperature measurements (shaded) (exposed) revealed that experienced bees' (27°C-32°C) less often than (68.4% vs. 78.12%). This suggests may prefer due more stable profile. internal posts, whether or not, consistently 1.54–1.76°C warmer during hotter periods closer cooler periods, indicating inherent insulation properties metal notable difference observed late afternoon evening, suggesting active thermoregulation maintain temperature.
