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

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),
