Coevolution in host-parasite systems: behavioural strategies of slave-making ants and their hosts.
Recently, avian brood parasites and their hosts have emerged as model systems for the study of host-parasite coevolution. However, empirical studies of the highly analogous social parasites, which use the workers of another eusocial species to raise their own young, have never explicitly examined the dynamics of these systems from a coevolutionary perspective. Here, we demonstrate interpopulati...

امروزه مسئله ی اساسی در رویکرد های جدید زبانشناسی، ابعاد اجتماعی و ایدئولوژیک زبان تلقی می شود. گروه های مختلف اجتماعی، سیاسی و یا مذهبی از زبان به عنوان ابزاری برای دستیابی به اهداف درون گروهی خود استفاده می کنند (ون دایک، 2003). آنها معولا ایدئولوژی خود را صریحا ابراز نمی کنند بلکه آن را در غالب کلمات و ساختارهای زبانی پنهان نگه می دارند. تشخیص ایدئولوژی های پنهان در گفتمان نیازمند این موضوع ...
Increased host aggression as an induced defense against slave-making ants
Slave-making ants reduce the fitness of surrounding host colonies through regular raids, causing the loss of brood and frequently queen and worker death. Consequently, hosts developed defenses against slave raids such as specific recognition and aggression toward social parasites, and indeed, we show that host ants react more aggressively toward slavemakers than toward nonparasitic competitors....

15 صفحه اولProblem of behavioral plasticity in slave-making Amazon-ant Polyergus rufescens Latr. and in its slave-ants Formica fusca L. and Formica cinerea Mayr.
Changes in the natural behavior, expressing adaptation to cohabitation in a community, were observed in the slave-making ants P. rufescens and the slave-species F. fusca and F. cinerea. After a few raids, the initially undirected arousal evoked in the slaves by the amazons' raids, begins to acquire attributes appropriate to the situation, but completely different in both studied slave-species. ...
