Floral richness shapes plant-pollinator networks in urban agroecosystems Open
Species richness, a fundamental driver of agroecosystem function, is shaped by habitat management and landscape surroundings. Yet, delivery of ecosystem services, like pollination, in agroecosystems is dependent on ecological interactions,…

Shifts in host–parasitoid networks across community garden management and urban landscape gradients Open
Biological pest control relies on interactions between herbivores and their natural enemies. Maintaining this ecosystem service requires considering herbivore and natural enemy interactions and their response to anthropogenic change at mul…

Landscape features, garden management, and microhabitats influence prey removal and predator composition in urban agroecosystems Open
Agroecosystem management at microhabitat, habitat, and landscape scales shapes natural enemy communities, with critical implications for ecosystem services. Yet few studies examine the impacts of small to large scale habitat management fea…

Land tenure security and luxury support plant species and trait diversity in urban community gardens Open
Urban ecological communities are shaped by an array of environmental and physical factors that include climate, biogeography, species interactions, dispersal, and ecological filters at the habitat and landscape scales. In addition, many so…

Promoting Beneficial Arthropods in Urban Agroecosystems: Focus on Flowers, Maybe Not Native Plants Open
(1) Urbanization threatens biodiversity, yet urban native plants support native biodiversity, contributing to conservation and ecosystem services. Within urban agroecosystems, where non-native plants are abundant, native plants may boost t…

Multiple ecosystem service synergies and landscape mediation of biodiversity within urban agroecosystems Open
Ecosystem services (ESs) are essential for human well‐being, especially in urban areas where 60% of the global population will live by 2030. While urban habitats have the potential to support biodiversity and ES, few studies have quantifie…

Rarity begets rarity: Social and environmental drivers of rare organisms in cities Open
Cities are sometimes characterized as homogenous with species assemblages composed of abundant, generalist species having similar ecological functions. Under this assumption, rare species, or species observed infrequently, would have espec…

Differences in insectivore bird diets in coffee agroecosystems driven by obligate or generalist guild, shade management, season, and year Open
Neotropical shade-grown coffee systems are renowned for their potential to conserve avian biodiversity. Yet, little is known about food resources consumed by insectivorous birds in these systems, the extent of resource competition between …

Cascading Effects of Birds and Bats in a Shaded Coffee Agroforestry System Open
Volant vertebrate insectivores, including birds and bats, can be important regulators of herbivores in forests and agro-ecosystems. Their effects can be realized directly through predation and indirectly via intraguild predation. This pape…

Social Context Influence on Urban Gardener Perceptions of Pests and Management Practices Open
Community gardens are important urban green spaces with a variety of social and ecological benefits, one of which is access to healthy food. Similar to rural agriculture, the quantity and quality of the food produced can be compromised by …

Gardener demographics, experience, and motivations drive differences in plant species richness and composition in urban gardens Open
Urban agriculture has received considerable attention for its role in supporting biodiversity and ecosystem services, and health and well-being for growing urban populations. Urban gardens managed with agroecological practices and higher p…
View article: Local and Landscape Drivers of Carabid Activity, Species Richness, and Traits in Urban Gardens in Coastal California
Local and Landscape Drivers of Carabid Activity, Species Richness, and Traits in Urban Gardens in Coastal California Open
Urban ecosystems, as mosaics of residential, industrial, commercial, and agricultural land, present challenges for species survival due to impervious surface, degradation, fragmentation, and modification of natural habitat, pollution, and …
View article: Agroecological Pest Management in the City: Experiences from California and Chiapas
Agroecological Pest Management in the City: Experiences from California and Chiapas Open
Urban gardens are a prominent part of agricultural systems, providing food security and access within cities; however, we still lack sufficient knowledge and general principles about how to manage pests in urban agroecosystems in distinct …

Gardener Well-Being along Social and Biophysical Landscape Gradients Open
Increasing human populations are challenging cities to grow sustainably while maintaining green spaces that deliver ecosystem services and well-being benefits. Community gardens are green spaces that provide food, community, and health ben…

People or place? Neighborhood opportunity influences community garden soil properties and soil-based ecosystem services Open
Soils are the foundation for cultivating ecosystem services in urban agriculture. Yet, variations in socio-environment characteristics of urbanization leads to variable soil properties and unequal distribution of ecosystem services like so…
View article: Local and landscape drivers of predation services in urban gardens
Local and landscape drivers of predation services in urban gardens Open
In agroecosystems, local and landscape features, as well as natural enemy abundance and richness, are significant predictors of predation services that may result in biological control of pests. Despite the increasing importance of urban g…

Urban arthropods respond variably to changes in landscape context and spatial scale Open
Urbanization and urban landscape diversity influence arthropods, but the influence of landscape factors differs based on arthropod life history strategies and the spatial scale of the analysis. Most research on landscape factors has focuse…

Landscape and Local Correlates of Bee Abundance and Species Richness in Urban Gardens Open
Urban gardens may preserve biodiversity as urban population densities increase, but this strongly depends on the characteristics of the gardens and the landscapes in which they are embedded. We investigated whether local and landscape char…
