Recognition of Host Plant Volatiles by Pheidole minutula Mayr (Myrmicinae), an Amazonian Ant-Plant Specialist
In the tropics, several ant species are obligate inhabitants of leaf pouches and other specialized structures in plants known as myrmecophytes. However, the cues used by ant queens to locate suitable host-plants following dispersal remain poorly understood. Here we tested the hypothesis that Pheidole minutula queens use volatiles to distinguish their host Maieta guianensis (Melastomataceae) fro...
متن کاملSignificant reproductive skew in the facultatively polygynous ant Pheidole pallidula.
Reproductive skew - the extent to which reproduction is unevenly shared between individuals in a social group - varies greatly between and within animal species. In this study, we investigated how queens share parentage in polygynous (multiple queen) colonies of the Mediterranean ant Pheidole pallidula. We used highly polymorphic microsatellites markers to determine parentage of gynes (new quee...
متن کاملStem diversity, cauline domatia, and the evolution of ant-plant associations in Piper sect. Macrostachys (Piperaceae).
Plants possess a variety of structures that harbor ant nests, and the morphology of these domatia determines the nature of ant-plant mutualisms in a given plant species. In this study, we report on the differences in anatomy between myrmecophytes of Piper, which are regularly excavated by an obligate ant mutualist (Pheidole bicornis) and nonmyrmecophytes of Piper, which consistently have solid ...
متن کاملCharacterizing the Cauline Domatia of Two Newly Discovered Ecuadorian Ant Plants in Piper: An Example of Convergent Evolution
The stems of some myrmecophytes in Piper are used as domatia by resident ant colonies. Hollow, ant-occupied stems were previously known only in four species of southern Central American Piper, all members of Section Macrostachys. Here we present two additional, unrelated, hollow-stemmed myrmecophytes from Ecuador: P. immutatum and P. pterocladum (members of sections Radula and Peltobryon, respe...
متن کاملEvaluation of antioxidant and anticoagulation activity of Piper chaba stem
Piper chaba Hunter, a flowering vine of Piperaceae family, has been using for long time in south Asian country for culinary meat preparation. As stem and root of this plant has been using traditionally in fat rich meat preparation, the antioxidant and anticoagulation potential of this herb is a great interest of study and it was evaluated using cold and boiled water extract of dried and grinded...
