Urbanisation drivers and underlying mechanisms of terrestrial insect diversity loss in cities

Ecological Entomology, Journal Year: 2021, Volume and Issue: 46(4), P. 757 - 771

1. Urbanisation is one of the main land‐use changes behind global insect collapse. Despite that previous studies have described negative effects urbanisation on communities, so far there no synthesis considers multiple urban drivers, their combined effects, and role species traits altogether. 2. Here we developed an integrative framework underlying mechanisms terrestrial loss in cities by exploring five leading drivers: impervious surfaces, habitat fragmentation, heat island, pollution, exotic plants. For each driver, identified direct indirect (mediated through interactions or resources) populations emphasising as moderators such effects. 3. Body size, mobility, oviposition/nesting requirements were frequently defined vulnerability to drivers. Urban island pollution deserve further research from a community‐level approach. Direct drivers dominated literature, while most paths mediated resources rather than interactions. 4. In conclusion, our review showed challenges recognising particular for driver By doing so, intended encourage researchers address some gaps noticed order fully understand how affecting communities. Finally, outlined recent planning strategies future successfully conserve biodiversity.

Urban Heat Island and Reduced Habitat Complexity Explain Spider Community Composition by Excluding Large and Heat-Sensitive Species

Land, Journal Year: 2024, Volume and Issue: 13(1), P. 83 - 83

Published: Jan. 11, 2024

Along with worldwide urbanization, upheavals in habitat and temperature are major threats for biodiversity. However, due to their interdependence, relative roles as drivers of animal community composition remain entangled. Here, we investigated how taxonomic functional compositions arthropod communities were related uncorrelated gradients, compared landscape (i.e., Urban Heat Island (UHI)) local variables vegetation height cover, near-ground temperature). We sampled 20,499 spiders (137 species) on 36 grasslands Rennes (northwestern France). Unlike rural areas, urban sites characterized by short intense UHI, hosted species-poor communities, composed small thermophilic species. UHI intensification loss complexity (short dense vegetation) associated declining large heat-sensitive These results highlight the prevalent role warming, rather than land cover change, an filter. Further, show that landscape-scale not temperature, filters species according attributes. can therefore be considered a thermal barrier, filtering physiological capacity cope conditions. Finally, counterbalance biotic homogenization, argue importance implementing complex structures at scale within green infrastructure.

Urban greening with shrubs can supercharge invertebrate abundance and diversity

Scientific Reports, Journal Year: 2024, Volume and Issue: 14(1)

Published: April 16, 2024

Abstract In urban areas, diverse and complex habitats for biodiversity are often lacking. This lack of diversity not only compromises essential ecological processes, such as pollination nutrient cycling, but also diminishes the resilience ecosystems to pests diseases. To enhance biodiversity, a possible solution is integrate shrubs alongside trees, thereby increasing overall amount vegetation, structural complexity associated resource diversity. Here, using common garden experiment involving variety trees planted alone in combination, we evaluate how canopy-associated invertebrate assemblages influenced by vegetation type. particular, test whether presence shrubs, or with results increased abundance taxonomic richness invertebrates, compared on their own. We found that specific functional groups (e.g., herbivores, pollinators, detritivores), was higher when were combination (relative own). Our suggest planting shrub tree species wide dense crowns can increase group communities. Overall, our findings indicate planning would benefit from incorporating maximise abundance, function landscapes.

Local Habitat Complexity and Its Effects on Herbivores and Predators in Urban Agroecosystems

Insects, Journal Year: 2024, Volume and Issue: 15(1), P. 41 - 41

Published: Jan. 7, 2024

In urban community gardens, cultivated vegetation provides variable levels of habitat complexity, which can suppress pests by promoting predator diversity and improving pest control. this study, we examine three components the structural complexity garden (cover, diversity, connectivity) to investigate whether higher leads fewer herbivores, more predators, predation. We worked in eight gardens where quantified sampled arthropod community, measured predation on corn earworm eggs. found that plots with high cover supported species richness greater abundance predatory insects. High also a spiders. contrast, was negatively associated abundance. While positively egg predation, had negative impact suggesting antagonism between predators may limit biological Community gardeners thus manipulate promote their plots. However, composition prevalence interspecific ultimately determine subsequent impacts

Abstract Understanding how anthropogenic activities induce changes in the functional traits of arthropod communities is critical to assessing their ecological consequences.

Abstract Urban parks are an important part of urban ecosystems and play role in biodiversity conservation. However, it is still unclear how park characteristics affect plant diversity which could hinder the conservation due to ineffective design parks.
