FORUM FORUM FORUM Population: a central concept for ecology?

When my colleague Mauricio Lima sent me the accompanying paper (Camus and Lima 2002) it rekindled my interest in an unfinished manuscript that attempts to address some of the questions and problems they pose. The ideas presented in this essay are based on the premise that ecology needs a central unifying concept upon which to build a coherent and practical discipline. I will argue that, from a ...

Retailing is a huge industry. In the United States, retail business represents about 40% of the economy and is the largest employer. Retail supply chain management is still more art than science, but this is changing rapidly as retailers begin to apply analytic models to the huge volume of data they are collecting on consumer purchases and preferences.

Studies on Organogenesis

1. Isolated blood cells, when placed for incubation in a plasma substratum, are capable of constructing highly organized, tubular processes that project from the explanted cell mass into the surrounding medium. 2. The tubular structures have fibrillar walls that may be covered, eventually, by a membranous layer of leukocytes. Their lumina contain blood cells suspended in fluid. 3. The formation...

Organogenesis: Drosophila goes gonadal

In many animals, germ cells migrate to the gonad to assemble into a functional organ. Recent work in Drosophila has built a picture of the gene activities that specify the gonad and allow it to attract germ cells, and has led to the identification of a gene, columbus, that may encode the attractive factor.
