Abstract Increasing urbanisation and rapid climate change are causing organisms to redistribute across environments. However, the specific factors that influence local spatial community or population dynamics often elusive, even less is known about impact of tropical urban landscapes on diverse species assemblages. In this study, we used a survey dataset with 510 fruit-feeding butterflies comprising 20 address knowledge gap. To understand butterfly in context daily environmental changes two heterogenous habitats within city Nigeria, assess abundance, richness, diversity indices along thirty-six (36) spots where were sampled spanning habitats, savannah woodland gallery forest. We constructed generalised linear models differential responses conditions habitats. Fruit-feeding butterflies’ diversity, abundance significantly differed between being higher when compared Furthermore, found richness increased due warmer temperatures. contrast, decreased forest extreme conditions. Thus, our study highlights may be shaped response microclimates heterogeneity despite more open habitat types, serving as refuge certain species.

Abstract The replacement of natural areas due to urbanisation represents a major threat wildlife. Wild species may be classified according their response towards urban areas. Such responses lead persistence (exploiters and tolerant) or local extinction (avoiders) within cities, which in turn contributes shaping the assemblages found therein, usually specific sets ecological morphological traits. Here, we focus on Orthoptera as model group test hypotheses relationships between species' traits environments, using city Rome, Italy, study area. By compiling comparing checklists for two distinct time frames, assessed assemblage variation across last three decades revealed that is trait‐biased. Species with low mobility fertility, narrower—more specialised—climatic niches showed higher probability extinction. Our results point at both climate land use changes potentially drivers orthopterans' areas, suggesting strategies increase habitat preservation connectivity, mitigate climate‐change induced events, prove effective sustaining richer insect communities

Mitigating the biodiversity crisis will require an understanding of how species cope with various human disturbances habitats ranging from fully natural environments to areas higher anthropization levels. In this study, we investigated local demographics Clonistria guadeloupensis (Redtenbacher) relate such as agricultural fields, roads, and urbanization in Guadeloupe. We sampled diverse environmental situations wild, both on around focal food plants, recorded habitat characteristics. subsequently analyzed demography juvenile, subadult, adult stages. found minimal impact factors, a tendency be associated greater levels, possibly because are generally more open. also variation aggregation levels developmental stages, which may reflect bias dispersal during stage males highly motile.

Abstract Urban ecosystems are formed by pronounced socio‐ecological gradients, which distinct from other and can simultaneously filter promote taxa, ultimately affecting their interactions. However, the strength of effect filtering facilitation across different trophic levels could vary among biotic abiotic factors. Here, we investigate effects habitat amount, temperature host‐enemy interactions in shaping communities cavity‐nesting bees wasps natural enemies. We installed trap‐nests 80 sites distributed along urban intensity gradients five European cities (Antwerp, Paris, Poznan, Tartu Zurich). quantified species richness abundance hosts enemies, as well two performance traits (survival parasitism) life‐history (sex ratio number offspring per nest for hosts). analysed importance variables using generalised linear models multi‐model inference. found that amount was main driver multiple host responses, with larger amounts resulting higher a probability survival brood cells hosts.
