Promoting urban biodiversity for the benefit of people and nature

In an increasingly urbanized world, urban biodiversity is people's primary contact with nature. However, as cities expand and densify, green blue spaces their are under pressure, risking declines in liveability.

Drivers of arthropod biodiversity in an urban ecosystem

Our world is becoming increasingly urbanized with a growing human population concentrated around cities. The expansion of urban areas has important consequences for biodiversity, yet the abiotic drivers biodiversity in ecosystems have not been well characterized most diverse group animals on planet, arthropods. Given their great diversity, comparatively small home ranges, and ability to disperse, arthropods make an excellent model studying which factors can accurately predict biodiversity. We assessed effects (i) topography (distance natural ocean) (ii) (mean annual temperature diurnal range), (iii) anthropogenic (land value amount impervious surface) occurrence six arthropod groups represented Malaise trap collections run by BioSCAN project across Greater Los Angeles Area. found striking heterogeneity responses all both within between taxonomic groups. Diurnal range had consistently negative effect occupancy but this was only significant Phoridae. Anthropogenic mixed though mostly insignificant effects, as some species were highly areas, while other showed suppressed diversity. Only Phoridae significantly affected land value, where more likely occur lower value. support high regional spatial community composition dependent group.

Island-wide removal of honeybees reveals exploitative trophic competition with strongly declining wild bee populations

High densities of managed honeybees (Apis mellifera) can threaten wild bees through exploitative competition, thus leading to population declines the latter. Although reviews have outlined key steps demonstrate these impacts-measuring resource overlap, changes in bee behavior, and trends-studies that comprehensively address aspects are virtually absent. We were granted access entire protected island Giannutri (2.6 km2) apiary (18 hives) located there during early phase coexistence between bees. Using as an open-air laboratory, we experimentally manipulated honeybee pressure by closing hives on selected days peak foraging period. In plants most visited pollinators, even short-term removals (11 h per day) increased nectar volume (∼60%) pollen availability (∼30%). absence honeybees, target (Anthophora dispar Bombus terrestris) became dominant insect-plant visitation network, potential apparent competition significantly decreased. Accordingly, both species intensified their activity suction time, a recognized proxy for quantity probed nectar, terrestris also shortened time searching. Transect monitoring revealed alarming ∼80% decline over 4 years, consistent with monopolization floral resources, reducing pollinators altering budget. These findings underscore risks introducing high into areas emphasize need rigorous preventive ecological assessments.

Insect ecology and conservation in urban areas: An overview of knowledge and needs

Insect Conservation and Diversity, Год журнала: 2024, Номер 17(2), С. 169 - 181

Опубликована: Март 1, 2024

Abstract Urban expansion across the globe profoundly impacts local biodiversity. The growing body of urban ecology research on animals has largely focused mammals and birds, whereas knowledge insect conservation in areas remains limited. To anchor this Special Issue (SI), we have taken a broad approach to editorial conducted structured literature search set scene. We provide here an overview existing reviews conservation, indicate where articles included SI contribute developing our understanding point priority for further investigation. Key themes (at individual, species, and/or community level) include influence habitat quality, quantity land use type diversity; anthropogenic pollution (for instance, heat, noise, light chemicals); connectivity changes structure density genetic diversity. Insect diversity abundance broadly decline with loss habitat. Beyond this, variation responses different taxa, or regions, methodological limitations individual studies make it challenging identify general patterns. environments should focus applying ecological theory understand patterns; investigating interactions between climate change contexts; identifying novel biodiversity; addressing harmonising approaches; exploring social historical factors must also consider into how best communicate value insects humans.

How Informed Design Can Make a Difference: Supporting Insect Pollinators in Cities

Pollinators are responsible for the reproduction of many plant and crop species provide important diversity food webs cultural value. Despite critical ecosystem services provided by pollinators, rapid pollinator declines occurring in response to anthropogenic activities that cause loss suitable habitat. There is an opportunity urban green space support pollination locally across landscape. However, there a lack practical but evidence-based guidance on how can be designed effectively floral resources other habitat needs diverse assemblage pollinators. We examine existing research this paper address following questions specific insect pollinators temperate settings: (1) Which focus efforts increase cities? (2) plants what arrangements most attractive supportive pollinators? (3) What do need beyond resources? (4) How surrounding landscape inform where prioritize new creation within Using these as framework, we informed management planning recommendations optimize value settings.
