Kin Discrimination Increases with Genetic Distance in a Social Amoeba
In the social amoeba Dictyostelium discoideum, thousands of cells aggregate upon starvation to form a multicellular fruiting body, and approximately 20% of them die to form a stalk that benefits the others. The aggregative nature of multicellular development makes the cells vulnerable to exploitation by cheaters, and the potential for cheating is indeed high. Cells might avoid being victimized ...
متن کاملAlternate-2 disjunction in the german cockroach.
The evidence in support of two types of alternate disjunction in translocation heterozygotes from the German cockroach, Blattella germanica (L.), is reviewed. When unique cytomorphological features occur in the translocation figure, the two types of alternate disjunction are identifiable regardless of the angle of observation. Photographs supporting this contention are presented for alternate-1...
متن کاملEffects of foraging distance on macronutrient balancing and performance in the German cockroach Blattella germanica.
The German cockroach (Blattella germanica) is an excellent model omnivore for studying the effect of foraging effort on nutrient balancing behavior and physiology, and its consequences for performance. We investigated the effect of foraging distance on individual German cockroaches by providing two foods differing in protein-to-carbohydrate ratio at opposite ends of long containers or adjacent ...
متن کاملodor-tracking performance in the American cockroach Periplaneta americana
Determining the location of a particular stimulus is often crucial to an animal’s survival. One way to determine the local distribution of an odor is to make simultaneous comparisons acrossmultiple sensors. If the sensors detect differences in the distribution of an odor in space, the animal can then steer toward the source. American cockroaches, Periplaneta americana, have 4 cm long antennae a...
متن کاملDisruption of GABAA in the insect antennal lobe generally increases odor detection and discrimination thresholds.
Studies of olfactory function show that disruption of GABA A receptors within the insect antennal lobe (AL) disrupts discrimination of closely related odors, suggesting that local processing within the AL specifically enhances fine odor discrimination. It remains unclear, however, how extensively AL function has been disrupted in these circumstances. Here we psychophysically characterize the ef...
