Brood parasitism reduces but does not prevent Bombus terrestris reproductive success
Insect Science, EarlyView.Graphical depiction of the colony splitting process. Throughout figures in this paper, results pertaining to host success are represented in blue, and cuckoo success is represented in red. Abstract Cuckoo bumblebees are obligate brood parasites that must invade a colony of their host bumblebee species in order to reproduce.

Nectar antimicrobial compounds and their potential effects on pollinators
, 2021 Nectar is a sugary, aqueous solution that plants offer as a reward to animal mutualists for visitation. Since nectars are so nutrient-rich, they often harbor significant microbial communities, which can be pathogenic, benign, or even sometimes beneficial

Insect Science, EarlyView.The Moorland Clouded Yellow (Colias palaeno) benefited from cattle grazing in three different ways by (i) fostering the nectar supply; (ii) enhancing rejuvenation of the host plant (Vaccinium uliginosum); and (iii) improving microclimatic conditions for successful development of the immature stages.

Florivory shapes both leaf and floral interactions
Ecosphere, 2016 Florivory, or the consumption of flowers, is a ubiquitous interaction that can reduce plant reproduction directly by damaging reproductive tissues and indirectly by deterring pollinators.

Agricultural and Forest Entomology, EarlyView.We applied three thiamethoxam spray treatments to buckwheat border strips: control (no nearby spray), drift (adjacent peach trees directly sprayed) and direct spray (buckwheat and peaches directly sprayed). Drift‐treated buckwheat received about 1.4% the amount of thiamethoxam as direct‐spray buckwheat. This amount has no lethal effects on parasitoids,

Ants contribute to raspberry pollination in protected cropping systems
Agricultural and Forest Entomology, EarlyView.Ants visited raspberry flowers more frequently than European honey bees (Apis mellifera), Australian stingless bees (Tetragonula carbonaria) and flies, many transporting raspberry pollen on their bodies, indicating potential pollination capacity. Ants were active flower visitors at most times of the day and may extend the daily pollination window and ...

The dual crisis: Climate change simultaneously drives pollinator decline and Pest outbreaks
Agricultural and Forest Entomology, EarlyView.Climate change acts as an asymmetric ecological filter, favouring r‐selected pest traits (rapid reproduction, generalism) while disadvantaging K‐selected pollinators. For every 1°C of warming, bee species richness declines ~25% since the 1990s, while pest‐induced crop losses increase by 10%–25%. A network‐centric approach integrating climate‐responsive

The role of non-volatile chemicals of floral rewards in plant-pollinator interactions
Basic and Applied EcologyThe interaction between plants and pollinators has intrigued scientists for centuries. While it continues to be [a] subject of ongoing research in basic and applied ecology, we tend to ignore that plant-pollinator interactions are largely driven by ...

Energy and water balance in the lesser double-collared sunbird, Nectarinia chalybea
, 1999 Bibliography: leaves 164-172.Nectarivores feed on aqueous sugar solutions, and their water balance is tightly linked to their energy balance. When nectar is dilute and energy demands are high, consumption of a large excess of preformed water is ...

Variation in nectar quality across 34 grassland plant species
, 2022 Floral nectar is considered the most important floral reward for attracting pollinators. It contains large amounts of carbohydrates besides variable concentrations of amino acids and thus represents an important food source for many pollinators.
