a preliminary study of the cleptoparasitic bees of the genus coelioxys (hymenoptera: megachilidae) in northern iran, with six new records
a survey on the megachilid bees (hymenoptera: megachilidae) fauna of northern iran, between 2010 and 2011, led to the identification of eleven species of the genus coelioxys latreille belonging to subgenera allocoelioxys (6 species), boreocoelioxys (2 species), coelioxys (2 species) and liothyrapis (1 species). of these, six species and one subgenus (liothyrapis) are new to the fauna of iran. d...
متن کاملBees
Chromosome segregation during cell division in higher eukaryotes is driven by a microtubule spindle formed in the cytoplasm. To allow the interaction of microtubules and chromosomes, the nuclear envelope breaks down in prophase, leading to an ‘open’ mitosis. Nuclear envelope breakdown occurs by stepwise disassembly of nuclear pore complexes, inner nuclear membrane proteins and, finally, lamins,...
متن کاملParameter Estimation of Loranz Chaotic Dynamic System Using Bees Algorithm
An important problem in nonlinear science is the unknown parameters estimation in Loranz chaotic system. Clearly, the parameter estimation for chaotic systems is a multidimensional continuous optimization problem, where the optimization goal is to minimize mean squared errors (MSEs) between real and estimated responses for a number of given samples. The Bees algorithm (BA) is a new member of me...
متن کاملThe Bees among Us: Modelling Occupancy of Solitary Bees
Occupancy modelling has received increasing attention as a tool for differentiating between true absence and non-detection in biodiversity data. This is thought to be particularly useful when a species of interest is spread out over a large area and sampling is constrained. We used occupancy modelling to estimate the probability of three phylogenetically independent pairs of native-introduced s...
متن کاملWild bees enhance honey bees' pollination of hybrid sunflower.
Pollinators are required for producing 15-30% of the human food supply, and farmers rely on managed honey bees throughout the world to provide these services. Yet honey bees are not always the most efficient pollinators of all crops and are declining in various parts of the world. Crop pollination shortages are becoming increasingly common. We found that behavioral interactions between wild and...
