Local and landscape effects of field margins on aerially dispersing beneficial insects and spiders [PDF]

open access: yes, 2011
Field margins were implemented in UK agri-environment schemes with the aim to increase farmland biodiversity. Recently aerially dispersing aphid enemies have been shown to provide the majority of aphid control in winter wheat fields but there is a lack ...

Characterizing the nectar microbiome of the non-native tropical milkweed, Asclepias curassavica, in an urban environment.

open access: yesPLoS ONE, 2020
In increasingly urban landscapes, the loss of native pollen and nectar floral resources is impacting ecologically important pollinators. Increased urbanization has also brought about the rise of urban gardens which introduce new floral resources that may

Great Diversity of Insect Floral Associates May Partially Explain Ecological Success of Poison Ivy (\u3ci\u3eToxicodendron Radicans\u3c/i\u3e Subsp. \u3ci\u3eNegundo\u3c/i\u3e [Greene] Gillis, Anacardiaceae) [PDF]

open access: yes, 2018
Little is known about insect floral associates of poison ivy (Toxicodendron radicans, Anacardiaceae), despite the species’ ubiquity and importance in nature and society.

Nectar defense and hydrogen peroxide in floral nectar of Cucurbita pepo

open access: yesActa Agrobotanica, 2015
This study was carried out to investigate some similarities between the nectaries of <em>Nicotiana</em> sp. and <em>Cucurbita</em> pepo, such as starch accumulation in the nectary parenchyma, changes in nectary color during maturation, and the production of a large quantity of sucrose-dominant nectar.

Contrasting effects of yeasts and bacteria on floral nectar traits. [PDF]

open access: yesAnn Bot, 2018
Flowers can be highly variable in nectar volume and chemical composition, even within the same plant, but the causes of this variation are not fully understood. One potential cause is nectar-colonizing bacteria and yeasts, but experimental tests isolating their effects on wildflowers are largely lacking.

Assessing the role of dispersed floralresources for managed bees in providingsupporting ecosystem services for croppollination [PDF]

open access: yes, 2018
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

INVISIBLE FLORAL LARCENIES: MICROBIAL COMMUNITIES DEGRADE FLORAL NECTAR OF BUMBLE BEE‐POLLINATED PLANTS [PDF]

open access: yesEcology, 2008
The ecology of nectarivorous microbial communities remains virtually unknown, which precludes elucidating whether these organisms play some role in plant–pollinator mutualisms beyond minor commensalism. We simultaneously assessed microbial abundance and nectar composition at the individual nectary level in flowers of three southern

Composition and Host-Use Patterns of a Scarab Beetle (Coleoptera: Scarabaeidae) Community Inhabiting the Canopy of a Lowland Tropical Rainforest in Southern Venezuela [PDF]

open access: yes, 2019
The adult scarab beetle fauna of the canopy in a lowland tropical rainforest in southern Venezuela was observed and collected by means of a 42 m-tall tower crane for a complete year.

Impacts of soil nutrition on floral traits, pollinator attraction, and fitness in cucumbers (Cucumis sativus L.)

open access: yesScientific Reports, 2022
Annual plants allocate soil nutrients to floral display and pollinator rewards to ensure pollination success in a single season. Nitrogen and phosphorus are critical soil nutrients whose levels are altered by intensive land use that may affect plants ...

Draft genome of Rosenbergiella nectarea strain 8N4T provides insights into the potential role of this species in its plant host. [PDF]

open access: yes, 2020
Background:Rosenbergiella nectarea strain 8N4T, the type species of the genus Rosenbergiella, was isolated from Amygdalus communis (almond) floral nectar. Other strains of this species were isolated from the floral nectar of Citrus paradisi (grapefruit),
