Green roof effects on floral phenology and floral nectar resources

2023
This study investigates the potential for green roofs to support pollinator diversity and abundance in urban ecosystems through the altered floral phenology and floral abundance of plants. I compare floral phenology and the floral abundance of green roof plants to plants grown at grade on the Front Range in Fort Collins, Colorado, and how these changes

Spatially discrete disturbance processes enhance grassland floral resources

Journal of Applied Ecology, 2022
Abstract Grasslands provide essential floral resources for both managed and wild pollinators. However, grassland flowers in remaining native landscapes are threatened due to non‐native plant invasions and alterations to historic disturbance regimes such as fire and grazing.

Patterns of Individual Variability in Floral Resources

Ecology, 1988
The distribution and presentation of floral rewards to insects has been demonstrated to influence pollinator visitation rates, pollinator movements, and consequent plant fitness. However, very little is known about the extant variation in nectar rewards among individuals in a single population.

Resource‐ and pollinator‐mediated selection on floral traits

Functional Ecology, 2016
Summary Female reproductive success is predicted to be simultaneously limited by the availability of pollen and resources. Selection on floral traits results from both factors, but their relative importance and interaction is poorly understood.

Floral resources enhance aphid suppression by a hoverfly

Entomologia Experimentalis et Applicata, 2011
AbstractThe reduction in floral diversity that often accompanies agricultural intensification may compromise the effectiveness of many natural enemies. Field studies examining the effects of floral resources on natural enemy fitness have been rare, however, particularly for predators such as hoverflies.

Floral Longevity: Fitness Consequences and Resource Costs

1996
Floral longevity (the period of time from anthesis to floral senescence) plays an important role in the reproductive ecology of plants. As noted by Primack (1985), the length of time a flower is open can influence its total number of pollinator visits, which, in turn, can affect the amount and diversity of pollen a flower receives, and the amount of ...

Measuring parasitoid movement from floral resources in a vineyard

Biological Control, 2008
Abstract The movement of natural enemies from floral resources is of particular importance in habitat manipulation research, as the distances that they disperse have consequences for the deployment of floral resources to improve insect natural enemy fitness.

Floral And Faunal Resources In Maharashtra

IntroductionThe wide variety in physical features and climatic factors in the State of Maharashtra have resulted in diversity of ecological habitats like forests, mountain, semi-arid, wetlands, coastal and marine ecosystems, which harbour and sustain rich floral and faunal diversity.

Floral Resource Utilization by Stingless Bees (Apidae, Meliponini)

2005
In this chapter, we examine patterns of floral resource utilization, mechanisms of floral resource partitioning, and foraging responses to general flowering (GF) according to studies on coexisting stingless bee species in the Lambir Hills National Park, or, LHNP (Nagamitsu and Inoue 1997b, 1998, 2002; Nagamitsu et al. 1999b).

Responses of Social and Solitary Bees to Pulsed Floral Resources

The American Naturalist, 2013
Pulsed food resources lead to mismatches between distribution of consumers and resources in space and time. Many studies have investigated how pollinators and floral resources covary in space, but few have looked at their covariance among years. I studied responses of two bee taxa, Bombus (a social genus) and Anthophora (a solitary genus), to variation
