Pollinator behaviour and resource limitation maintain honest floral signalling [PDF]

open access: yesFunctional Ecology, 2021
Abstract In many communication systems, signal receivers profit from honest signals that indicate the signaller's quality, whereas low‐quality signallers should profit from cheating. Under such a conflict of interests between signallers and signal receivers, the maintenance of honest signals presents a puzzle.

Floral UV Features of Plant Species From a Neotropical Savanna

open access: yesFrontiers in Plant Science, 2021
Despite the wide interest in flower colours, only after the end of the nineteenth-century studies started to comprise floral UV reflection, which is invisible to humans but visible to the major groups of pollinators.

Honeybee Floral Resources in Southwestern Nigeria

open access: yesJournal of Biology and Life Science, 2012
Every beekeeper is expected to be familiar with the bee floral resources near/ or around his/her apiary for successful beekeeping operation. Understanding the major nectar and pollen producing plants and their flowering period is of great advantage to maximise the efficiency of the bees.

Ants as flower visitors : floral ant-repellence and the impact of ant scent-marks on pollinator behaviour [PDF]

open access: yes, 2012
As flower visitors, ants rarely benefit a plant, commonly disrupting pollination by deterring other flower visitors, or stealing nectar. This thesis examines three aspects of ant-flower interactions, focusing on the occurrence of floral traits that ...

Floral Plantings in Large-Scale Commercial Agroecosystems Support Both Pollinators and Arthropod Predators

open access: yesInsects, 2021
Beneficial insect populations and the services that they provide are in decline, largely due to agricultural land use and practices. Establishing perennial floral plantings in the unused margins of crop fields can help conserve beneficial pollinators and

How Effective Is Conservation Biological Control in Regulating Insect Pest Populations in Organic Crop Production Systems?

open access: yesInsects, 2020
Organic crop production systems are designed to enhance or preserve the presence of natural enemies, including parasitoids and predators, by means of conservation biological control, which involves providing environments and habitats that sustain natural
