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.

Assessing Ecological Gains: A Review of How Arthropods, Bats and Birds Benefit from Green Roofs and Walls

Environments, Год журнала: 2024, Номер 11(4), С. 76 - 76

Опубликована: Апрель 10, 2024

Because of the immense amount infrastructure in cities, introduction vegetation into these constructions is expected to play a critical role reducing heat island effect, mitigating effects climate change, and supporting habitat connectivity associated biodiversity. Although there perception that solutions can improve biodiversity their real value still unclear. This paper focuses on two aspects urban greening: green roofs walls. It provides systematic review present walls, through an exhaustive worldwide literature analysis. Arthropods, bats, birds were three taxonomic groups analyzed papers included our review. We observed strong increase number recent publications, thus demonstrating growing interest this topic. In summary, we found roofs/walls offered additional opportunities for plants animals thrive environments because creation greater spatial connectivity. addition, enhancement other ecosystem services such as stormwater management mitigation was noted. By incorporating features design planning, cities support while also improving overall sustainability livability spaces.

Urban wild bee well‐being revealed by gut metagenome data: A mason bee model

Abstract Wild bees are ecologically vital but increasingly threatened by anthropogenic activities, leading to uncertain survival and health outcomes in urban environments. The gut microbiome contains features indicating host reflecting long‐term evolutionary adaptation acute reactions real‐time stressors. Moving beyond bacteria, we propose a comprehensive analysis integrating diet, bacteriome, virome, resistome, their association understand the status of lives better. We conducted study on mason ( Osmia excavata ) across 10 agricultural sites Suzhou, China, using shotgun metagenome sequencing for data derived from total DNA. Our findings revealed that most ingested pollen originated Brassica crops unexpected garden tree Plantanus , floral resources at supported with limited plant diversity. Varied city landscapes site‐specific flowers all contributed sustenance. bacterial community, dominated Gammaproteobacteria, showed remarkable structural stability 8 suggested perturbations 2 sites. Antibiotic resistance gene profiles highly varied prevalent unclassified drug classes, highlighting environmental threats both humans. virome identified honeybee pathogens, suggesting potential virus spillover. Many unknown bacteriophages were detected, some which targeted core underscoring role maintaining homeostasis. These multifaceted metagenomic insights hold predict bee identify threats, thereby guiding probiotic development management effective conservation.

Influence of traffic‐related pollution and seasonality on tardigrade diversity in urban ecosystems

Insect Conservation and Diversity, Год журнала: 2025, Номер unknown

Опубликована: Май 21, 2025

Abstract Urbanization negatively impacts biodiversity, particularly through habitat modification and pollution. While invertebrate diversity changes along urban gradients, the effects of vehicular pollutants remain understudied. This study investigated influence traffic seasonality on tardigrade in Salta, a rapidly expanding city Argentina. We aimed to assess how different levels intensity microhabitat conditions affected species richness composition across seasons. conducted sampling winter summer at sites classified as having high, medium or low levels. A total 2254 tardigrades from 6 genera 11 were identified. No significant seasonal differences found abundance, composition. Notably, medium‐traffic exhibited lower richness, suggesting instability due fluctuating pollution Species differed significantly between levels, with Macrobiotus olgae Rocha et al., 2024 (Parachela: Macrobiotidae) Milnesium quiranae 2022 (Apochela: Milnesiidae) identified ecological indicators tolerance contamination thresholds, respectively. Beta analysis showed that turnover was main factor caused assemblage, while nestedness explained loss Our findings underscore detrimental assemblages highlight need for biodiversity conservation strategies environments, developing countries. research contributes understanding dynamics informs management practices mitigating meiofauna.

Metabarcoding assessment of arthropod diversity on green roofs in the metropolitan city of Hamburg

Journal of Urban Ecology, Год журнала: 2025, Номер 11(1)

Опубликована: Янв. 1, 2025

Abstract Cities have become valuable alternative habitats for many organisms, particularly arthropods, as they often offer more favourable environmental conditions, and greater resource availability compared to neighbouring intensive agroecosystems. However, urban biodiversity is threatened by habitat loss fragmentation, driven mainly development densification. Green roofs are novel green spaces that may represent stepping stones, supporting various taxa. so far, only few studies evaluated the potential of support conservation in cities. Here, we assessed species richness diversity vascular plants arthropods on eight extensive city Hamburg northern Germany understand which local roof parameters landscape scale factors high arthropod roofs. Plant varied between roofs, but none explained variance plant diversity, with age having a slightly negative effect. Arthropod was positively influenced size composition In addition, amount land use types surrounding location had positive effect richness. Our results indicate can harbor could function stones enhance connectivity existing and, thereby, biodiversity.

How well do trees fit the city? Lessons from an urban tree survey in Córdoba, Argentina.

Boletín de la Sociedad Argentina de Botánica, Год журнала: 2023, Номер 58(4)

Опубликована: Дек. 22, 2023

Background and aim: Urban tree composition is generally highly diverse largely non-native in origin. Species selection, however, should consider not only future predicted climate species' environmental requirements, but also the regional invasion risk assessments respiratory health potential of species. Here, we assessed suitability most frequent urban species by using available online databases. M&M: Suitability was analysing attributes relation to their invasive status study area, given known pollination strategy bioclimatic match with plantation zone. We grouped according nativeness as non-native, regionally native local native. After filtering those undesirable characteristics (i.e., and/or anemophilous strategy) analysed three variables: annual temperature, precipitation seasonality. Results: Results showed that Córdoba's street trees heavily biased towards species, many which are invasive, have an exhibit high mismatch. In addition, strong bias current from more humid, temperate regions evident. Conclusions: Our results highlight importance revising policy decisions adjust flora face change.
