Abstract Fallen fruits provide important feeding and breeding substrates for insects such as Drosophilidae can be a potential trophic reservoir when usual host become scarce. Recently, two invasive fruit fly species, Drosophila suzukii Chymomyza amoena , have established in Europe are expected to alter existing communities. In this study, carried out between September 2021 April 2022 northern France, we aimed disentangle the relative roles of microclimatic, landscape local factors driving diversity community decaying across seasons. Minimum site temperature during week preceding sampling proportion rotten tissue had strongest positive influence on abundance species richness. also increased with urbanisation (portion building cover) around sampled trees. Decaying apples were sites C. seasons, but provided suboptimal substrate D. which was only present late summer. This study sheds light role unharvested fallen crop maintaining an insect family that is generally overlooked field studies. It emphasises importance considering multiple scales studying interactions native their shared resources. Finally, our data highlight recycling agricultural waste.

Abstract Urbanization is a major cause of global insect declines, yet some species can persist, and even thrive, in cities. Research on butterflies frequently report reduced diversity urban habitats compared to rural ones, but less known about whether urbanization favours with specific functional traits. Further, few studies have evaluated leads the biotic homogenization butterfly communities, despite being reported for other taxa. Here, we investigate how community composition changes along an gradient by surveying 44 sites around Montréal, Quebec, Canada. We test hypothesis that communities are homogenized at taxonomic levels. found clear differences structure versus areas favouring few, highly abundant, non‐native species. These shifts were defined losses native richness abundance combined increases abundance. For most community, longer flight periods more common areas. Finally, levels as demonstrated reductions beta variation several key traits (wingspan, larval diet breadth, oviposition style) ones. Overall, this region support diverse homogenized. Since growing worldwide, better understanding arises what its consequences will be guiding future conservation efforts.

ABSTRACT Although Syrphidae is an essential family of flies because they provide key ecosystem services like pollination and pest control, their richness abundance respond negatively to urbanisation, even when high‐quality green spaces are present. These the conclusions many studies from northern hemisphere; however, there shortfalls in our knowledge flower fly ecology Neotropical megacities. We used a 10‐year dataset obtained long‐term citizen science program devoted test whether richness, total number records (as proxy abundance) diversity could be influenced by space predictors such as surface percentage areas, quality public squares parks indices greenness index (NDVI) across 34 municipalities Greater Santiago. Furthermore, we described for first time interaction network exclusively within city. analysed 1084 607 interactions 29 species. found that north‐east have more Based on abundance, two‐way Jaccard analysis grouped into three major clades: (a) those with than 10 species, (b) between five species (c) fewer Generalised linear mixed models associated positively significantly diversity, mainly mean NDVI value. The structure plant showed low values connectance specialisation, but significant value diversity. information help local decision‐makers improve management municipality's spaces, enhance biodiversity inside cities potential or control.

Abstract Scientific and public interest in the global status of insects has surged recently; however, understanding relative importance different stressors their interconnections remains a crucial problem. We use meta-synthetic approach to integrate recent hypotheses about insect responses into network containing 3385 edges 108 nodes. The is highly interconnected, with agricultural intensification most often identified as root cause. Habitat-related variables are connected appear be underdiscussed other stressors. also identify biases gaps literature, especially those generated from focus on economically important popular insects, pollinators, at expense non-pollinating less charismatic insects. In addition serving case study for how meta-synthesis can map conceptual landscape, our results many where future meta-analyses will offer critical insights mitigating biodiversity loss.

Abstract Recent work has shown the decline of insect abundance, diversity and biomass, with potential implications for ecosystem services. These declines are especially pronounced in regions high human activity, urbanization is emerging as a significant contributing factor. However, scale these traits that determine variation species‐specific responses remain less well understood, subtropical tropical regions, where urban footprints rapidly expanding. Here, we surveyed moths across an entire year protected forested sites gradient to test how caterpillar adult life stages (Lepidoptera) impacted by urbanization. Specifically, assess development affects total biomass caterpillars, abundance quantify richness phylogenetic macro‐moths development. Additionally, explore life‐history condition species' At community level, find decreases moth abundance. We also sharp response phylogeny, leading decrease species more sites. Finally, our study found smaller than larger environments, perhaps highlighting tradeoffs metabolic costs heat favoring over relative benefits dispersal moths. In summary, research underscores far‐reaching consequences on provides compelling evidence forests alone may not be sufficient safeguard biodiversity cities.

Abstract Green-blue urban infrastructures potentially offer win-win benefits for people and nature in areas. Given increasing evidence of widespread declines insects, as well their ecological importance, there is a need to better understand the potential role green-blue infrastructure insect conservation. In this review, we evaluated 201 studies about ability support diversity. Most were focused on local landscape-level characteristics infrastructure. Fewer explicitly compared one type another, even fewer communities between traditional Overall, body research highlights importance plant diversity reduced intensity management (e.g., mowing) most taxon groups. While seem be generally more important than landscape factors, within can also depend connectivity context. Some types are beneficial others; instance, ground-level habitats tend insects green roofs. Few simultaneously studied synergies or trade-offs with other services provided by infrastructure, but environmental variables, such tree cover diversity, that affect likely provision improving thermal comfort well-being people.

Abstract Insects, like many organisms, face widespread human‐driven habitat transformations which are major threats to biodiversity. However, at the same time, transformed areas including cities increasingly being colonised by wildlife, sometimes serving as important refuges for vulnerable species. Most studies on traits that enable insects thrive in urban environments have focused morphology, physiology, and feeding or reproductive strategies, often overlooking behavioural traits, despite evidence from vertebrates showing tolerance towards humans is key wildlife successfully colonise cities. In this study, we tested effects of urbanisation, along with a range life‐history, environmental contextual humans—measured flight initiation distance—in 14 Odonata (dragonflies damselflies) species western Poland. We found escape distances were moderately repeatable within Urbanisation had generally weak effect behaviour; however, odonates delayed their sites high human presence. also tended increase observer’ starting distance species‐specific body size decrease perch height. Additionally, male more likely earlier than females. These results suggest can sense levels anthropogenic disturbance adjust behaviour accordingly. Furthermore, our findings indicate some basic patterns principles commonly reported vertebrates, such ability tolerate presence mass, may apply invertebrates. This implications understanding ecology evolution antipredator strategies conservation.

Urbanization presents significant challenges to biodiversity but also offers opportunities for its protection and development. While uncontrolled urban expansion has a destructive impact on biodiversity, effective planning can play positive role in protecting maintaining biodiversity. The of human factors, such as planning, protect maintain the healthy development This study conducted an in-depth analysis evolution various wildlife migration corridors throughout full-cycle construction Xiong’an New Area (Xiong’an) China, revealing urbanization these networks. Habitats species like Sus scrofa, Bufo gargarizans, Parus minor have notably increased. Between 2016 2023, scrofa habitats grew from 35 44, large-toed frog 24 35, Chinese tit remained stable. By phase, expanded 87, 97, 58. Habitat areas significantly, especially which increased 2873.84 hectares 7527.97 phase. Large-toed 2136.86 6982.78 hectares, while 1894.25 3679.71 hectares. These changes suggest that parks green spaces provided more extensive species. In terms networks, number dispersal routes considerably. 2016, had 77 routes, frogs 16, tits 77. 91 49, respectively, surged 232, 249, 152, indicating denser network. distribution ecological pinchpoints changed significantly. 2023 were concentrated densely built areas, reflecting urbanization’s resilience, assessed through network performance, showed gradual recovery. connectivity index decreased 8.25 7.29 then rebounded 11.37 ecosystem adapted after initial pressures.
