Abstract Background and Aims The impact of urbanization on plant evolution, particularly the evolution reproductive traits, remains largely unknown. In this study, we aimed to investigate consequences traits Portulaca oleracea in Kantō region Japan. has a unique cleistogamous system, which consists genetically determined chasmogamous (open, CH) (closed, CL) plants. Methods We collected seeds P. from ten populations rural areas urban areas. common garden experiment, recorded type flowers (CH or CL), phenology seed production. Key Results All individuals produced either CH CL flowers, allowing us classify them as observed significant difference prevalence plants between populations: number was generally low among individuals. Compared plants, showed earlier heavier seeds, is consistent with stress avoidance response heat drought conditions Conclusions Our findings suggest that may drive an evolutionary change system oleracea. larger might be better adapted environments, where they are subjected harsh stress.

Artificial light at night (ALAN) is exerting growing pressure on natural ecosystems, but its impact biological interactions remains unclear. This study aimed to assess how ALAN influences leaf functional traits and herbivory in two prevalent street tree species ( Styphnolobium japonicum (L.) Schott Fraxinus pennsylvanica ) through field surveys paired experiments the urban areas of Beijing, China. We found that led increased toughness decreased levels herbivory. Additionally, showed species-specific effects nutrients, size as well defense substances. The findings illustrate can significantly alter some key ecological processes (nutrient cycling, energy flow). In general, we suggest high intensity will be detrimental flow from plants higher trophic levels, posing a potential threat maintenance biodiversity (e.g., arthropod diversity, bird diversity) ecosystems.

Abstract Urbanization is one of the most significant contributors to Anthropocene, and urban evolutionary ecology has become an important field research. While it commonly assumed that cities impose new stronger selection, contradictory assertion selection may be relaxed in also frequently mentioned, overall, our understanding effects urbanization on natural incomplete. In this review, we first conduct a literature search find evidence for patterns phenotypic traits including morphology, physiology, behaviour life history, non‐urban populations animals plants. This reveals coefficients context are scarce ( n = 8 studies providing gradients/differentials include total 200 coefficients) lack standardized methods hinders quantitative comparisons across (e.g. with meta‐analysis). These studies, however, provide interesting insight agents shaping improve mechanistic processes at different spatial scales. We then perform second review genomic assessing intensity cities, genome non‐human populations. returns 383 articles, only 34 these truly investigate footprints associated urbanization, study provides genetic coefficients. Here again, highly heterogeneous approaches, yet some strong adaptation. neither nor were able quantitatively assess versus habitats. Thus, propose roadmap how future should metrics facilitate mega‐ or meta‐analyses explore generalized selection. Read free Plain Language Summary article Journal blog.
