Reproductive biology of pointleaf manzanita (Arctostaphylos pungens) and the pollinator-nectar robber spectrum

open access: yesJournal of Pollination Ecology, 2012
Floral visitor species are often assumed to act either mutualistically towards plants (as pollinators) or to exploit them (as nectar-robbers or as nectar or pollen thieves).

Fitness Effects of Food Resources on the Polyphagous Aphid Parasitoid, Aphidius colemani Viereck (Hymenoptera: Braconidae: Aphidiinae). [PDF]

open access: yesPLoS ONE, 2016
Conservation biological control involving the polyphagous aphid parasitoid, Aphidius colemani Viereck, may include provisioning resources from a variety of plant sources. The fitness of adult A.

Nectar as food for birds: The physiological consequences of drinking dilute sugar solutions [PDF]

open access: yes, 2003
Nectarivory has evolved many times in birds: although best known in hummingbirds, sunbirds and honeyeaters, it also occurs on an opportunistic basis in a varied assortment of birds. We present a phylogenetic analysis of the distribution of nectarivory in

EVALUATION OF FLORAL CHARACTERISTICS OF MELON HYBRIDS (Cucumis melo L.) IN POLLINATOR ATTRACTIVENESS

open access: yesRevista Brasileira de Fruticultura, 2016
Floral morphology and biology are important characteristics for plant-pollinator interactions and may influence the behavior of these agents. This study aimed to determine which floral attributes of different melon hybrids influence this interaction and,

Safe sex: ant defense does not interfere with pollination in passion flowers

open access: yesActa Botânica Brasílica, 2021
Ant defense against floral enemies incurs a two-fold ant-pollinator conflict, both via pollinator deterrence and nectar or pollen collection by non-pollinating protective ants.

Is there a diel pattern to nectar secretion in the Red Bloodwood Corymbia gummifera? [PDF]

open access: yes, 2013
Nectar secretion was measured at 6-h intervals over a 24-h period in flowers of the Red Bloodwood, Corymbia gummifera (family Myrtaceae). Secretion varied among time periods and among trees. There was no clear diurnal or nocturnal pattern.

New perspectives in nectar evolution and ecology: simple alimentary reward or a complex multiorganism interaction?

open access: yesActa Agrobotanica, 2017
Floral and extra-floral nectars are secretions elaborated by specific organs (nectaries) that can be associated with plant reproductive structures (the so-called floral nectaries found only in angiosperms) or vegetative parts (extrafloral nectaries ...

Microbe-mediated alterations in floral nectar: consequences for insect parasitoids [PDF]

open access: yes, 2023
Floral nectar is frequently colonized by microbes among which bacteria and yeasts are the most abundant. These microbes have the ability to alter nectar characteristics with consequences for the whole community of flower-visiting insects. Recent research

Dracula’s mistress: removal of blood-red floral nectar results in secretion of more nectar

open access: yesPlant Ecology and Evolution, 2020
Background and aims – Flowers of Jaltomata quipuscoae (Solanaceae) secrete blood-red nectar that serves as an energy reward and possible attractant to pollinators. The purposes of this study were to determine whether simulated pollinator visits (manual removal of nectar) stimulates replenishment of nectar, and report the pattern of nectar presentation ...
