Streszczenie:

Most pollination ecosystem services studies have focussed on wild pollinators and their dependence on natural floral resources adjacent to crop fields. However, managed pollinators depend on a mixture of floral resources that are spatially separated from the crop field. Here, we consider the supporting role these resources play as an ecosystem services provider to quantify the use and availability of floral resources, and to estimate their relative contribution to support pollination services of managed honeybees.

Knowledge of the flowering process — an important trait in ornamental plants such as roses — is necessary for efficient control of flowering. This study was carried out to develop and characterize new resources to gain further insight into floral control in rose. We studied floral initiation in a nonrecurrent blooming rose (hybrid of Rosa wichurana ) and a recurrent blooming rose ( Rosa hybrida Black Baccara®). In Black Baccara®, floral initiation took place rapidly after bud burst, whereas in the greenhouse R. wichurana remained vegetative. During floral initiation, the apex enlarged and dome

Resource allocation in floral exudate composition is a trade-off between energy cost to the plant and pollinator reward. For example, carbohydrates offer less reward to pollinators but at less cost to the plant when compared with lipids. We suggest plant and community allocation to carbohydrates and lipids may vary across environmental gradients, with plants in resource-limited communities able to allocate fewer resources to higher-cost compounds in floral exudates. Plant and community resource allocation is important for understanding the behavior of pollinators and understanding how it relat

Background Pollinating insects provide economically and ecologically valuable services, but are threatened by a variety of anthropogenic changes. The availability and quality of floral resources may be affected by anthropogenic land use. For example, flower-visiting insects in agroecosystems rely on weeds on field edges for foraging resources, but these weeds are often exposed to agrochemicals that may compromise the quality of their floral resources. Methods We conducted complementary field and greenhouse experiments to evaluate the: (1) effect of low concentrations of agrochemical exposure o

The decline of pollinating insects in agricultural landscapes proceeds due to intensive land use and the associated loss of habitat and food sources. The feeding of those insects depends on the spatial and temporal distribution of nectar and pollen as food resource.

We addressed this issue by quantifying floral resources (i.e., number of flowers, nectar volume and number of pollen grains) and monitoring pollination interactions in dry grassland co

The Caatinga, a dry forest vegetation of northeastern Brazil, has a diverse flora high species number and β diversity, but remains under-sampled. The clime and vegetation make the region a great beekeeping producer, and floristics surveys are essential to the preservation and multiplication of focal species for the activity. The state of Piauí has been prominent as beekeeping producer, especially in the Caatinga areas. However, due to the dry season, it is also necessary to evaluate the richness of species found during this season and their potential as bee forage. We surveyed plant species oc

Background Managed populations of the alfalfa leafcutting bee (ALCB), Megachile rotundata (F.), are often not sustainable. In addition to numerous mortality factors that contribute to this, the dense bee populations used to maximize alfalfa pollination quickly deplete floral resources available to bees later in the summer. Providing alternative floral resources as alfalfa declines may help to improve ALCB reproduction. Methods We examined the relationship between floral resource availability and ALCB reproduction and offspring condition via (1) a field study using alfalfa plots with and withou

Crassulaceae of the Kalanchoe laetivirens species have ornamental potential, but are poorly studied, especially their reproductive biology and trophic resources made available to visitors. The aim of this study, therefore, was to characterize the reproductive system of K. laetivirens through analyses of floral morphology, trophic resources and floral visitors. Floral structures, pollen / egg ratio, in vitro pollen germination, pollen grain structure in scanning microscopy and the availability of trophic resources by the evaluation of potential and instant nectar were described.

Summary Floral traits, including floral display and nutritional rewards from pollen and nectar, drive pollinator visitation. Even within a single plant species, environmental factors can influence the quality and quantity of floral resources. Yet, the ecological interactions driving this variation in floral resources, especially those belowground, remain unknown. Here, we investigate how soil microbial community composition and nutrient availability, specifically distinct arbuscular mycorrhizal fungi (AMF) species and phosphorus (P) supply, affect plant growth, AMF traits, floral traits, and h

The study was carried out to verify if there are differences in foraging frequency and behavior of Apis mellifera in two melon hybrids (10:00 – ‘Yellow melon’ and Sancho -‘Piel de Sapo’) in the municipality of Juazeiro, state of Bahia, Brazil. The frequency, behavior of visitors and the floral resource foraged were registered from 5:00 am to 6:00 pm. There was a significant difference in the frequency of visits when comparing hydrids (F = 103.74, p <0.0001), floral type (F = 47.25, p <0.0001) and resource foraged (F = 239.14, p <0.0001).

Abstract European honey bees have been introduced across the globe and may compete with native bees for floral resources. Compounding effects of urbanization and introduced species on native bees are, however, unclear. Here, we investigated how honey bee abundance and foraging patterns related to those of native bee abundance and diversity in residential gardens and native vegetation remnants for 2 years in urbanized areas of the Southwest Australian biodiversity hotspot and assessed how niche overlap influenced these relationships. Honey bees did not overtly suppress native bee abundance; how

Clerodendrum infortunatum L. (Family: Lamiaceae) is a naturally growing shrub of medicinal value. The plant has woody stem, elliptical leaves and sweet-smelling flowers borne on pyramid-shaped peduncle panicle. The leaves and calyces are provided with EFNs which produce extra floral nectar while floral nectaries produce nectar rich in sucrose and amino acids. These food resources attract several floral and extra floral arthropod visitors like butterflies, bees, ants, bugs, grasshoppers, spiders etc. which can be grouped as EFN visitors, potential pollinators, herbivores and predators.

The Cerrado, the world’s most diverse savanna, has several adaptations to fire. However, intense and frequent fires, especially after frosts, can severely impact this ecosystem. Despite this, few studies have evaluated the combined effects of frost followed by fire. We investigated how these disturbances affect plant traits, floral resources, floral visitor richness, and the structures of plant–pollinator interaction networks by using Byrsonima intermedia, a common Malpighiaceae shrub, as a model.

Abstract The loss of floral resources is a leading cause of wild bee decline in agricultural landscapes, but little is known about the temporal aspects of floral resource limitation for both social and solitary bees. Understanding when floral resources are most needed is crucial for the optimal design of pollinator conservation measures. We surveyed bees and flowers in 160 semi‐natural habitat patches multiple times per year (May–July) for 5 years. We identified the seasonality of floral resources and wild bees and examined inter‐ and intra‐annual patterns of floral resource limitation at both

Specialisation enhances the efficiency of plant–pollinator networks through the exchange of conspecific pollen transfer for floral resources. Floral resources form the currency of plant–pollinator interactions, but the understanding of how floral resources affect the structure of plant–pollinator networks remains modest. Previous theory predicts that optimally foraging animal species will specialise to improve resource acquisition under high resource availability. Although floral resource availability depends on both the plant production and animal consumption of the resources, previous work h
