Ordinations of Habitat Relationships among Breeding Birds
I N an attempt to express habitat relationships in a new way, I have applied two methods of multivariate analysis to a large set of data pertaining to the habitats of 46 species of common breeding birds. The question asked was : How do these species distribute themselves with respect to the structure of the vegetation? This required (1) devising field techniques that would give quantitative mea...

15 صفحه اولUse of DDT for the Control of Cyclops Breeding and as an Antidracontiasis Measure
Till now for control of dracontiasis, the drinking water sources showing prolific breeding of c;/clops in endemic areas were either super' chlorinated or the biological method of control by introduction of cyclopscidal fishes like Ambassis, Etroplus, Barbus etc., was resorted to after the removal of the predatory fishes. Super-chlorination, if done regularly, gives fairly good results but socia...
متن کاملRelationships among some univariate distributions
The purpose of this paper is to graphically illustrate the parametric relationships between pairs of 35 univariate distribution families. The families are organized into a seven-by-five matrix and the relationships are illustrated by connecting related families with arrows. A simplified matrix, showing only 25 families, is designed for student use. These relationships provide rapid access to in...
