Web services have already achieved a solid level of acceptance and play a major role for the rapid development of loosely-coupled component-based systems, overcoming heterogeneity within and between enterprises. Current developments in the world of services on the Web are marked by the proliferation ofWebAPIs andWeb applications, commonly referred to as RESTful services, which show high potenti...

polymerase chain reaction and restriction fragment length polymorphism (pcr-rflp) and phylogenetic analysis were used for molecular identification of lactic acid bacteria (labs) isolated from apis mellifera. eighteen honeybee workers were collected from three different apiaries in west azerbaijan. labs from the gut of honeybees were isolated and cultured using routine biochemical procedures. ge...

background: the varroa destructor varroasis is a very serious parasite of honeybee apis mellifera . the objective of this study was to evaluate the effectiveness of varroa treatment using organic acid (oxalic acid) in algeria identify­ing its side effects on bee colonies. methods : treatment was conducted in one apiary consisting 30 colonies kept in langstroth hives kind. oxalic acid dripped di...

Predator-prey relationships between sympatric species allow the evolution of defense behaviors, such as honeybee colonies defending their nests against predatory wasps. We investigated the predator-prey relationship between the honeybee (Apis mellifera ligustica) and the European wasp (Vespula germanica) by evaluating the effectiveness of attack and defense behaviors, which have coevolved in th...

Axis formation is a key step in development, but studies indicate that genes involved in insect axis formation are relatively fast evolving. Orthodenticle genes have conserved roles, often with hunchback, in maternal anterior patterning in several insect species. We show that two orthodenticle genes, otd1 and otd2, and hunchback act as maternal anterior patterning genes in the honeybee (Apis me...

The odor localization strategy induced by odors learned via differential conditioning of the proboscis extension response was investigated in honeybees. In response to reward-associated but not non-reward-associated odors, learners walked longer paths than non-learners and control bees. When orange odor reward association was learned, the path length and the body turn angles were small during o...

Aasrancr: Two African races of the honey bee (Äpis mellifera capansis and A. m. scutellatal have a signilicantly shorter postcapping stage of worker brood than A. rn. carnica. An average within-race heritability of this character is estimated as h2 = 0.8. Reciprocal crosses between the races show that the duration of the postcapping stage also is maternaffy affected (m = 0.23). As the reproduct...

Apis mellifera L. is native to Europe, Africa, and Asia (including Saudi Arabia, Iran and the Ural mountains of Russia). It is currently widely distributed across the world due to multiple migrations and introductions (Ruttner, 1988). Apis mellifera includes about two dozen subspecies that are present in different regions of the world. These subspecies have been classified into five main lineag...

The engineering of large-scale decentralised systems requires sound methodologies to guarantee the attainment of the desired macroscopic system-level behaviour given the microscopic individual-level implementation. While a general-purpose methodology is currently out of reach, specific solutions can be given to broad classes of problems by means of well-conceived design patterns. We propose a d...

The recently developed geometric morphometrics methods represent an important contribution of statistics and geometry to the study of biological shapes. We propose simple protocols using shape distances that incorporate geometric techniques into linear quantitative genetic models that should provide insights into the contribution of genetics to shape variation in organisms. The geometric approa...
