Honeybees directly outcompete other flower visitors through interference competition on shared resource

open access: yesEcological Entomology, EarlyView.
The outcomes of encounters between honeybees and other flower visitors were observed on two plant species. Pollinators either win, lose or share a resource. Competitive interactions led to greater than expected ‘wins’ for honeybees. The honeybee displaced or gave chase when interacting with another pollinator in at least 20% of winning outcomes ...

Mapping wild bee diversity and flower use for an effective conservation of the Doñana biodiversity hotspot

open access: yesInsect Conservation and Diversity, EarlyView.
We compiled the first checklist of wild bees in Doñana Protected Area, documenting 385 species, including three vulnerable and one endangered species listed in the Red List. Bee species exhibit diverse floral preferences, highlighting the need to incorporate plant–pollinator interactions and the role of plants in conservation and management strategies ...

Local habitat, not landscape diversity, drives richness and reproduction of cavity‐nesting bees and wasps in agricultural landscapes

open access: yesInsect Conservation and Diversity, EarlyView.
Local habitat type and hedgerow cover strongly shape bee and wasp richness, but only weakly their reproductive output, outweighing the landscape diversity effects at the 1‐km2 scale. Forests host more wasp but fewer bee species, whereas orchards support high richness of both; bee reproduction patterns are driven by one dominant species, while wasp ...

BIOACTIVE COMPOUNDS OF BLACKBERRY FRUITS (Rubus spp.) GROWN IN BRAZIL

open access: yes, 2015
The blackberry (Rubus spp.), a small fruit that grows in temperate climate, shows an attractive color ranging from purple red to blue, due to the high content of anthocyanins. The anthocyanins, along with carotenoids, are the major natural pigments found

Improving Decision‐Making in the Identification of Tephritidae Larvae at Import in the European Union and Key to Third Instar Larvae

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT The Tephritidae family, or true fruit flies, comprises approximately 250 species recognized as economically significant due to their capacity to infest commercial fruits. These pests pose serious threats to both food security and trade, and are considered quarantine pests in areas where they are not yet established. In the European Union (EU),

No need to seed: restoring species‐rich grassland on former arable fields by natural regeneration

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Over the last century, agricultural intensification has caused substantial losses of semi‐natural species‐rich grasslands. One means of restoring grassland habitat is to abandon farmed land, followed by mowing and/or grazing of the established vegetation to facilitate meadow diversification. Objectives This study investigated post‐
