Prudent sperm use by leaf-cutter ant queens.
In many species, females store sperm between copulation and egg fertilization, but the consequences of sperm storage and patterns of sperm use for female life history and reproductive success have not been investigated in great detail. In hymenopteran insect societies (ants, bees, wasps), reproduction is usually monopolized by one or relatively few queens, who mate only during a brief period ea...
متن کاملDiversity and Conservation of Leaf Cutter Bees (Hymenoptera: megachilidae)
More than one-third of the world’s crops require pollination to set seeds and fruits Dias et al. [1]. It is likely that wild bee community is sufficient to provide services for multiple crops, including some that are not serviced by honeybees Kremen et al. [2]. Under several situations non-Apis bees are better pollinators than Apis species because of efficient tripping, fast foraging rate, long...
متن کاملFrontier mutualism: coevolutionary patterns at the northern range limit of the leaf-cutter ant-fungus symbiosis.
Tropical leaf-cutter ants cultivate the fungus Attamyces bromatificus in a many-to-one, diffuse coevolutionary relationship where ant and fungal partners re-associate frequently over time. To evaluate whether ant-Attamyces coevolution is more specific (tighter) in peripheral populations, we characterized the host-specificities of Attamyces genotypes at their northern, subtropical range limits (...
متن کاملPolymorphic microsatellite markers for the symbiotic fungi cultivated by leaf cutter ants (Attini, Formicidae).
We developed 23 polymorphic microsatellite markers for the symbiotic fungi cultivated by leaf cutter ants, then assessed allelic variation in North American leafcutter-fungus populations (Mexico, Cuba, USA). Polyploidy was indicated by 21 of the 23 loci, consistent with the multinucleate nature of leafcutter fungi. Microsatellite fingerprinting can now assess fungal genetic variation within lea...
متن کاملMicrobial Community Structure of Leaf-Cutter Ant Fungus Gardens and Refuse Dumps
BACKGROUND Leaf-cutter ants use fresh plant material to grow a mutualistic fungus that serves as the ants' primary food source. Within fungus gardens, various plant compounds are metabolized and transformed into nutrients suitable for ant consumption. This symbiotic association produces a large amount of refuse consisting primarily of partly degraded plant material. A leaf-cutter ant colony is ...
