A fundamental notion in community ecology is that local species diversity reflects some balance between the contrasting forces of competitive exclusion and competitive release. Quantifying this balance is not trivial, and requires data on the magnitude of both processes in the same system, as well as appropriate methodology to integrate and interpret such data. Here we present a novel framework...

Universal grammar (UG) is a list of innate constraints that specify the set of grammars that can be learned by the child during primary language acquisition. UG of the human brain has been shaped by evolution. Evolution requires variation. Hence, we have to postulate and study variation of UG. We investigate evolutionary dynamics and language acquisition in the context of multiple UGs. We provi...

Bacteria and plants are able to form population waves in result of their consumer behaviour and propagation. A soliton-like interpenetration of colliding population waves was assumed but not proved earlier. Here we show how and why colliding population waves of trophically identical but fitness different species can interpenetrate through each other without delay. We have hypothesized and revea...

Female Safari cats are offspring of domestic and Geoffroy parents, and are balanced helcer,oz,rgc,tes with equal numbers of blood cells containing domestic as Geoffroy-type glucose 6-phosphate dehydrogenase (G6PD), an X-chromosome derived enzyme. In previous studies, however, we observed increasing percentages of blood cells with Geoffroy G6PD over 4-12 years. Similarly, ratios of parental X-ch...
