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

Arabian Archaeology and Epigraphy, EarlyView.
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.

First large-scale study reveals important losses of managed honey bee and stingless bee colonies in Latin America

Scientific Reports
Over the last quarter century, increasing honey bee colony losses motivated standardized large-scale surveys of managed honey bees (Apis mellifera), particularly in Europe and the United States.

AN EMPIRICAL ANALYSIS OF HONEYBEE POLLINATION MARKETS

Pollination by honeybees plays an important role in modern agriculture. Some crops are greatly dependent on honeybees (almonds, apples, avocados, blueberries, and cherries are examples) while the yields and quality of other crops are significantly ...

The limitations of the methods of identifying the floral source of honeys

, 1998
The pollen grains in honey reveal the types of plants that were around when the bees produced the honey, thus it is valid to use melissopalynology to determine the geographical origin of honeys, but there are several reasons why it is less valid for ...

Could learning of pollen odours by honey bees (Apis mellifera) play a role in their foraging behaviour?

, 2005
The role of pollen odour cues in the foraging behaviour of honey bees (Apis mellifera L.) is poorly understood. Using classical conditioning of the proboscis extension response, in which bees learn to associate an odour with a sucrose reward, the present

Annual flower strips under the ‘Sweden Blossom’ initiative – how do they perform for pollinators, natural enemies and herbivores?

Agricultural and Forest Entomology, EarlyView.
Pollinator‐targeted annual flower strips increase abundances of pollinators but also natural enemies and herbivores. Natural enemies and herbivores disperse in a taxon‐specific manner into nearby crops. Pest control by ground‐dwellers slightly increases in crop areas near the flower strips.

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 ...

Laboratory studies examining aspects of scent marking, traplining and remote detection of reward in the foraging bumblebee.

, 2007
PhDEnergy from food is essential for the survival of all animals. For decades, bumblebees have been used as model organisms for studying animal foraging strategies.

Further experiments on the drifting of honey-bees

, 1961
1. Worker bees learnt the colour of their hive in the close vicinity to their hive entrance and took little or no notice of colours above the lower brood chamber. They orientated to a colour below the entrance more than to a colour above.
