Fertilizer and herbicide alter nectar and pollen quality with consequences for pollinator floral choices [PDF]
PeerJ, 2023 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.

Can floral nectars reduce transmission of Leishmania? [PDF]
PLOS Neglected Tropical Diseases, 2021 ABSTRACT Insect-vectored Leishmania are the second-most debilitating of human parasites worldwide. Elucidation of the environmental factors that affect parasite transmission by vectors is essential to develop sustainable methods of parasite control that do not have off-target ...

A dataset of nectar sugar production for flowering plants found in urban green spaces
Ecological Solutions and Evidence, 2023 Nectar and pollen are floral resources that provide food for insect pollinators, so quantifying their supplies can help us to understand and mitigate pollinator declines.

Frontiers in Plant Science, 2020 The specialised mutualism between Tococa guianensis and ants housed in its leaf domatia is a well-known example of myrmecophily. A pollination study on this species revealed that flowers in the bud stage exude a sugary solution that is collected by ants.

Pollination by hummingbirds of Vriesea gigantea (Bromeliaceae) populations in Southern Brazil
Rodriguésia, 2020 The pollination syndrome hypothesis usually does not successfully apply to the diversity of floral phenotypes or help predict the pollinators of most plant species.

Nectar defense and hydrogen peroxide in floral nectar of Cucurbita pepo
Acta 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.

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
