Abstract Despite a growing literature‐base devoted to document biodiversity patterns in cities, little is known about the processes that influence these patterns, and whether they are consistent over time. In particular, numerous studies have identified capacity of cities host rich diversity plant species. This trend, however, driven primarily by introduced species, which comprise large proportion urban species pool relative natives. Using an experimental common garden study, we assessed local assembly (i.e., soil environmental filtering competition from spontaneous species) on taxonomic functional native communities sampled four seasons 2016–2018. Taxonomic exhibited different responses processes, supporting general conclusion species‐ trait‐based measures offer distinct insights into community dynamics. Additionally, found neither nor influenced or composition Functional composition, did shift strongly time was community‐weighted mean differences both measured traits (maximum height, Hmax; specific leaf area, SLA; chlorophyll fluorescence, Chl ) proportions groups (legumes, annual biennial‐perennial C4 grasses, forbs). By contrast, only diverged between early late seasons. Overall, our results indicate not capable establishing persisting vacant habitats, can functionally respond pressures suggests regional dispersal limitation may be primary factor limiting environments. Thus, future regreening management plans should focus enhancing potential environments, order achieve set goals for increasing associated ecosystem services cities.

Urban biodiversity plays a crucial role in the functioning of urban ecosystems and significantly impacts well-being quality life for city residents. By focusing on Porto as case study, influence local-scale land cover evolution is investigated, using species richness birds, reptiles, amphibians indicators, within multimodel inference framework. The results underscore importance past legacy shaping biodiversity. Birds, respond positively to older vegetation patches but negatively long-established areas. Birds exhibit adaptability by responding recent vegetation, while tend avoid newly vegetated zones. fragmented distribution reptiles suggests limited mobility potential delayed response habitat loss isolation. Reptiles benefit from both wooded herbaceous habitats, emphasizing local spatial diversity, water elements are critical amphibians, although many aquatic habitats context may not be suitable.

University campuses are important components of cities, harboring the majority urban biodiversity. In this study, based on monthly bird survey data covering 12 university located either downtown or in newly developed areas Nanjing, China, 2019, we studied assembly processes each campus’s population and their main drivers by modeling a set ecological landscape determinants. Our results showed that (1) abundance species diversity were significantly higher than those downtown; (2) phylogeny communities all universities followed pattern aggregation, indicating environmental filtering played major role community assembly; (3) specifically, grass, water, buildings factors affecting community’s functional phylogenetic diversity, with grass water habitats having significant positive correlation while size building was negatively correlated. emphasize habitat features play decisive determining processes. We suggest increasing e.g., reasonably arranging location area bodies grasslands improving connectivity, could be powerful way to maintain promote diversity.

The trends of land cover dynamics in cities have major repercussions on urban biodiversity, ultimately impacting the health and well-being human urbanites. Older habitats, i.e., habitats with higher spatiotemporal continuity, allow ecosystem processes promoting maintenance diverse microhabitats accommodation species over time, contributing for a richer biodiversity at city level beyond. Thus, we implement analysis trajectories proposed as an indicator habitat order to identify priority areas conservation or restoration that can be integrated planning. method was applied Porto, Portugal, it used detect main patches associated vegetation persistence, gain loss, between 1947 2019. most common change related urbanization processes, where artificial built elements replaced tree, shrub herbaceous cover, completely dominating territory 2019 (66% cover).

Residential yards and gardens can have surprisingly high plant diversity. However, we still do not understand all the factors that drive diversity in individual gardens, or how scale up to create larger patterns of urban biodiversity. For example, social interactions between neighbors could affect whether they mimic each other's yard design, affecting spatial turnover communities. Further, socio-economic differences neighborhoods might result distinct assemblages across a city. In this paper, used fieldwork, GIS, statistics examine variability front vegetation—both cultivated spontaneous plants—in 870 Chicago, Illinois (USA). Our goals were patterning communities residential vary with scale, considering alpha, beta, gamma We addressed following questions: (1) How plants different socioeconomic characteristics?

Urbanization in one of the more important phenomena affecting biodiversity Anthropocene. Some organisms can cope with urban challenges, and changes birds’ acoustic communication have been widely studied. Although timing daily organization previously reported, there is a significant gap regarding possible variations song structure between dawn dusk choruses. Considering that urbanization potentially imposes different soundscapes for choruses, we postulate two hypotheses: i) are “natural” parameters ii) such within city will vary response to noise. We studied extra-urban populations Chiguanco Thrush La Paz, Bolivia, measuring their choruses: length, sound pressure, minimum, maximum, range dominant frequency, proportion songs produced. The results support our natural conditions were louder larger bandwidths, city, frequency entire rises along increasing amplitude. Understanding structural choruses could allow better interpretation how some bird species challenges.

The probability presence Senegal parrot, rose-ringed parakeet, blue-crowned crested myna was positively influenced by number lists. For myna, year presence, suggesting an range. observed that spatio-temporal variations effort associated sources may generate bias trend estimates, therefore we recommend should always be accounted for. Our approach agreed with documented area, supporting usefulness providing on biological invasions ecosystems, particularly where best or only source information available.
