PROF. HUXLEY is very much within the mark when he estimates the species of insects at ``about 100,000, if not more.'' Were I to estimate the number of described species at 200,000, I believe the figures would also fall short of the truth, even allowing a liberal margin for synonyms...

The data for the commoner species was not so strictly `randomized', but the whole series could be closely fitted by a series of the logarithmic type as described by Fisher in Part 3. Other data for random collections of insects in the field were also shown to fit fairly well to this ...
Pseudonannolene mesai sp.n. from Biritiba Mirim, State of So Paulo, Brazil, is described and the chromosome number (2n=16) is reported. It was impossible to observe the chromosomal sex determination mechanism.doi:10.1590/S0101-81752000000100014FontanettiCarmem S...
Of note, it was recently shown that the original h u m a n ERR2 cDNA described in reference 1 is in fact of rat origin^. ERRl was also identified by three other groups as a regulator of SV40 major late promoter^ of the h u m a n lactoferrin gene^^ and of the h u m a n ...
Populations varied morphologically along an east-west gradient, from three distinct forms in the west to continuous intergradation in the east, in accord with earlier studies.Patellacollected were divided into three groups on the basis of a complex of external features described by earlier workers, ...
Previously reported methods for estimating the number of different alleles at a single locus in a population have not described a useful general result. Using the number of alleles observed in a sample gives an underestimate for the true number of alleles. The similar problem of estimating the nu...
