Flies use specialized photoreceptors R7 and R8 in the dorsal rim area (DRA) to detect skylight polarization. R7 and R8 form a tiered waveguide (rhabdom) with R7 on top, filtering light delivered to R8. We examine how the division of a given resource, rhabdom length,...

It is shown that the mass, metabolism and length explanation (MMLE) can simultaneously compute an animal’s body mass and BMR given its characteristic length using data for humans. MMLE was advanced in 1984 to explain the relationship between metabolic rate and...

There are three sex ratio strategies (SRS) in nature—male-biased sex ratio, female-biased sex ratio and, equal sex ratio depending on the proportion of male offspring being greater than, less than, or equal to ½. The problem was already noted in Darwin’s (1859)...

Aggregation during dispersal from source to settlement sites can allow persistence of weak competitors, by creating conditions where stronger competitors are more likely to interact with conspecifics than with less competitive heterospecifics. However, different...
