Pollination ecology of the invasive tree tobacco Nicotiana glauca: comparisons across native and non-native ranges

Journal of Pollination Ecology, 2012
Interactions with pollinators are thought to play a significant role in determining whether plant species become invasive, and ecologically generalised species are predicted to be more likely to invade than more specialised species.

Testing how antagonistic interactions impact the robustness of plant-pollinator networks

Journal of Pollination Ecology, 2019
Given ongoing pollinator declines, it is important to understand the dynamics of linked extinctions of plants driven by pollinator extinctions. Topological robustness models focused on this question suggest relatively high robustness of plant species to ...

Playback-elicited heterospecific aggressive responses in urbanized Sparkling Violetear are modulated in relation the risk of take-over hypothesis

Frontiers in Ecology and Evolution
Hummingbirds have crucial ecological importance in natural and human-altered habitats in the Neotropics. Their unique biological characteristics imply a delicate energetic balance that drove the evolution of species-specific dominance and territorial ...

Determination of the effect of electric fence system on productivity and behaviour of honeybees housed in different beehive types (Apis mellifera L.)

Italian Journal of Animal Science, 2019
This study was conducted in 2018 in order to determine the effects of an electric fence system on honeybee colonies housed in hives made from different materials. The experiment was carried out with honeybee colonies of 36 Caucasian races (Apis mellifera

The effects of nectar-robbing on fruit production in Sparattosperma leucanthum (Bignoniaceae)

, 2022
Many animals behave as robbers or thieves of floral resources, causing damage to floral tissues or consuming resources used to attract pollinators, or producing effects similar to emasculation by reducing the pollen load in the anthers (which generally results in losses in terms of sexual reproduction). The present work examined the direct and indirect

Flower-visiting lizards as key ecological actors for an endemic and critically endangered plant in the Canary Islands

Journal of Pollination Ecology
Oceanic islands are places where biological assemblages are relatively simple, as compared to the mainland. On islands, however, pollinator assemblages may to be composed of a taxonomically disparate group of organisms (e.g. insects, lizards, and birds),

MORPHOLOGICAL CONSTRAINTS AND NECTAR ROBBING IN THREE ANDEAN BUMBLE BEE SPECIES (HYMENOPTERA, APIDAE, BOMBINI)

Caldasia, 2006
We report differences in foraging behavior of three Andean bumblebee species onflowers of Digitalis purpurea (Scrophulariaceae). Bombus atratus was a potentialpollinator while B. hortulanus and B. rubicundus collected nectar by robbing throughholes.
