Although the value of urban ecological infrastructure (UEI) is widely recognized, insufficient research has investigated how people perceive the wide variety of UEI. To address this gap, we investigated residents’ perceptions of the coupled value of aesthetic and biological qualities as related to diverse UEI and other environmental and social factors (including personal beliefs and demographics), collectively referred to as bio-cultural services and disservices. We evaluated whether people positively view their neighborhood environments as natural-looking while providing diverse plants and wildlife habitat (services), in contrast to negatively perceived disservices that we evaluated as messy-looking with weeds and pests (disservices). We analyzed survey data from residents (n = 495) in metropolitan Phoenix, Arizona, United States, coupled with environmental variables (UEI and vegetative cover) compiled from diverse sources. We ran three regression models to compare the relative influence of social and environmental factors independently and combined on the perception of bio-cultural services and disservices. Our results demonstrate the influence of social factors, particularly place identity, neighborhood cohesion, and income, on both bio-cultural services and disservices. Additionally, environmental factors such as vegetation cover increased perceptions of bio-cultural services while decreasing perceived disservices. The effects of proximity to UEI were more varied. While proximity to cropland increased perceived bio-cultural disservices, proximity to desert parks reduced disservices. Although UEI can promote biodiversity and human well-being, all UEI are not perceived the same. Our results underscore the added value of considering both the form of UEI and perceptions among people who live nearby when designing and implementing infrastructure to promote bio-cultural services that are both ecologically and socially valued.

While recent studies explore the negative impacts of light pollution on arthropods, few studies investigated community-level responses to artificial light. Using an array of landscaping lights and pitfall traps, we track community composition over 15 consecutive days and nights, including a five-night pre-light period, a five-night during-light period, and a five-night post-light period. Our results highlight a trophic-level response to artificial nighttime lighting with shifts in the presence and abundance of predators, scavengers, parasites, and herbivores. We show that associated trophic shifts occurred immediately upon the introduction of artificial light at night and are limited to nocturnal communities. Lastly, trophic levels reverted to their pre-light state, suggesting many short-term changes in communities are likely the result of behavioral shifts. These trophic shifts may become common as light pollution increases, implicating artificial light as a cause of global arthropod community change and highlighting light pollution's role in global herbivorous arthropod decline.

When prioritizing regions for conservation protection, decisions are often based on the principle that a single large reserve should support more species than several small reserves of the same total area (SLOSS). This principle remains a central paradigm in conservation planning despite conflicting empirical evidence and methodological concerns. In urban areas where small parks tend to dominate and policies to promote biodiversity are becoming increasingly popular, determining the most appropriate prioritization method is critical. Here, we document the role of SLOSS in defining the seasonal diversity of birds in 475 parks in 21 US cities. Collections of small parks were consistently associated with higher species richness, spatial turnover and rarity. Collections of both small and large parks were associated with higher phylogenetic and functional diversity whose patterns varied across seasons and cities. Thus, collections of small parks are a reliable source of species richness driven by higher spatial turnover and rarity, whereas collections of both small and large parks contain the potential to support higher phylogenetic and functional diversity. The presence of strong intra-annual and geographical variation emphasizes the need for regional prioritization strategies, where multiple diversity metrics are examined across parks and seasons.

Negative interactions between people and wildlife pose a significant challenge to their coexistence. Past research on human–wildlife interactions has largely focused on conflicts involving carnivores in rural areas. Additional research is needed in urban areas to examine the full array of negative and positive interactions between people and wildlife. In this study, we have conducted interviews in the desert metropolis of Phoenix, Arizona (USA), to explore residents’ everyday interactions with wildlife where they live. Our multifaceted approach examines interactions involving physical contact and observational experiences, as well as associated attitudinal and behavioral responses and actions toward wildlife. Overall, the qualitative analysis of residents’ narratives identified two distinct groups: people who are indifferent toward wildlife where they live, and those who appreciate and steward wildlife. Instead of revealing conflicts and negative interactions toward wildlife, our findings underscore the positive interactions that can foster human wellbeing in urban areas. The holistic approach presented herein can advance knowledge and the management of coexistence, which involves not only managing conflicts but also tolerance, acceptance, and stewardship. Understanding diverse human–wildlife interactions and managing coexistence can advance both wildlife conservation and human wellbeing in cities.
