Florivory as an Opportunity Benefit of Aposematism [PDF]
The American Naturalist, 2015 Inconspicuous prey pay a cost of reduced feeding opportunities. Flowers are highly nutritious but are positioned where prey would be apparent to predators and often contain toxins to reduce consumption. However, many herbivores are specialized to subvert these defenses by retaining toxins for their own use.

Basic and Applied Ecology, 2023 Land-use and local field management affect pollinators, pest damage and ultimately crop yields. Agroecology is implemented as a sustainable alternative to conventional agricultural practices, but little is known about its potential for pollination and ...

An experimental investigation of costs of tolerance against leaf and floral herbivory in the herbaceous weed horsenettle (Solanum carolinense, Solanaceae) [PDF]
Plant Ecology and Evolution, 2021 Background and aims – A plant’s tolerance of herbivory depends on its ability to endure and compensate for damage so as to lessen the impact that herbivores have on the plant’s performance (e.g. its growth, reproduction, or fitness).

Florivory and pollinator visitation: a cautionary tale [PDF]
AoB PLANTS, 2015 Abstract Florivory, or damage to flowers by herbivores, can make flowers less attractive to pollinators, potentially resulting in reduced plant fitness. However, not many studies have combined observations with experiments to assess the causal link between florivory and pollination.

Sociobiology, 2013 The Malpighiaceae family is species-rich and is abundant in Brazil. Malpighiaceae flowers provide oil and pollen to pollinating bees and serve as food for herbivorous insects, which damage the floral structures.

Is protection against florivory consistent with the optimal defense hypothesis? [PDF]
BMC Plant Biology, 2016 Plant defense traits require resources and energy that plants may otherwise use for growth and reproduction. In order to most efficiently protect plant tissues from herbivory, one widely accepted assumption of the optimal defense hypothesis states that plants protect tissues most relevant to fitness.

Indirect Selection on Flower Color in Silene littorea
Frontiers in Plant Science, 2020 Flower color, as other floral traits, may suffer conflicting selective pressures mediated by both mutualists and antagonists. The maintenance of intraspecific flower color variability has been usually explained as a result of direct selection by biotic ...

Higher bee abundance, but not pest abundance, in landscapes with more agriculture on a late-flowering legume crop in tropical smallholder farms [PDF]
PeerJ, 2021 Background Landscape composition is known to affect both beneficial insect and pest communities on crop fields. Landscape composition therefore can impact ecosystem (dis)services provided by insects to crops. Though landscape effects on ecosystem service

Contrasting effects of plant population size on florivory and pollination
Basic and Applied Ecology, 2009 Abstract Changes in plant population size, induced by various forms of habitat degradation, can affect the performance of plants by altering their interactions with other organisms such as pollinators and herbivores. However, studies on plant reproductive response to variation in population size that simultaneously consider different interactions are

Frontiers in Plant Science, 2017 The global decline in pollinators has partly been blamed on pesticides, leading some to propose pesticide-free farming as an option to improve pollination.
