Food resources are more important than nesting resources for explaining wild bee diversity in urban gardens Nahrungsressourcen haben einen größeren Einfluss auf die Wildbienendiversität in urbanen Gärten als das Nistangebot

Insect Conservation and Diversity, EarlyView.
Urban community gardens showed a high wild bee diversity with 168 recorded species, representing roughly 30% of Germany's wild bees, including threatened species like Osmia mitis and Coelioxys lanceolata. Floral resources, not nesting resources or habitat availability, were the main drivers for wild bee taxonomic and functional diversity.

Phytochemical characterization of Borago officinalis L. and Centaurea cyanus L. during flower development.

Food Research International, 2019
The present work details the nutritional and chemical compositions of borage and centaurea, at three flowering stages. Water was the main constituent, followed by total dietary fiber. Both flowers showed statistically different (p

Unequal pollinator benefits from partial mowing regimes in a field experiment

Insect Conservation and Diversity, EarlyView.
Pollinators aggregate in unmown refuges in partially mown vegetation in the first days after mowing. Up to four weeks after mowing, this initial aggregation is followed by a subsequent decline in abundance not observed in unmown locations. This decline is paired with a species richness decrease, revealing that partial mowing filters pollinator ...

Flowering Plant Species Differ in Their Suitability for Orius strigicollis (Poppius): Effects on Plant Preference, Longevity and Oviposition Under Laboratory Conditions

Journal of Applied Entomology, EarlyView.
ABSTRACT Flowering plant species can support pest control by providing resources for natural enemies. Polyphagous predatory species of the genus Orius occur in many parts of the world and are widely used as biological control agents. They feed on several common pest species and can additionally utilize plant resources such as nectar and pollen.

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

Restoration 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‐

The Late Agricultural Development of Central Arabian Oases—Archaeobotanical and Archaeozoological Studies of the al‐Kharj Oasis

Arabian Archaeology and Epigraphy, Volume 37, Issue 1, Page 317-355, November 2026.
ABSTRACT While oasis settlements emerged during the Bronze Age in Eastern and Northern Arabia, the settlement process in Central Arabia was different. Excavations at al‐Yamāma—main ancient settlement of the al‐Kharj oasis (Riyadh Province, KSA)—suggest that the latter did not emerge before the second half of the first millennium BCE.
