13 More than 20,000 angiosperm species possess non-dehiscent anthers that open through small pores 14 at the anther's tip. These flowers are visited by bees that use vibrations to remove pollen, a 15 phenomenon known as buzz-pollination. However, some floral visitors fail to transfer pollen 16 efficiently, either through a mismatch of flower and insect size, or because they are unable to 17 buz...
The ancient and historic site of Bisotun is one of the most reliable archaeological works of the world, which was registered in the UNESCO World Heritage List in 2006. This research studies the economic value (including recreational value and existential value) of Bisotun Historical Complex using the Logit and Probit valuation models. The statistical population of the study was visitors to the ...
We studied the interaction between the plant Cnidoscolus multilobus, its floral visitors and the predator spider Peucetia viridans. The diet of P. viridans was composed exclusively of arthropods (spiders 32%, insects 68%). Body length of prey was 5.9 ± 1.0 mm, and prey size range was 11.0 ± 0.4 mm (i.e. 0.14-1.3 times larger than the spider). Based on feeding frequency and time available for pr...
AIM To explore whether and how health visitors experience ethical tensions between the public health agenda and the need to be responsive to individual clients. BACKGROUND Current health policy in England gives health visitors a key role in implementing the government's public health agenda. Health visitors are also required by their Professional Code to respond to the health-related concerns...
Buildings are usually conceived as expressing a static functionality where users are required to adapt to its pre-defined properties. This view of architecture is outdated. Buildings can be conceived and constructed as perceiving, acting and adapting entities not unlike biological systems. Although several existing projects have aimed at developing "smart" rooms or buildings, in most of these a...
Many recent studies have suggested that the majority of animal-pollinated plants have a higher diversity of pollinators than that expected according to their pollination syndrome. This broad generalization, often based on pollination web data, has been challenged by the fact that some floral visitors recorded in pollination webs are ineffective pollinators. To contribute to this debate, and to ...
