Larval competition in Drosophila melanogaster: frequency-dependence of viability
1988
The application of the overfeeding technique (interruption of the competition during larval development) to the study of larval competition in two-strain cultures of Drosophila melanogaster demonstrates the following points: (1) viability is a function of competition time; (2) viability becomes more frequency-dependent as competition time increases; (3) the dynamics of the “inner” subpopulation (adults that have passed all their development in a crowded condition) and “outer” subpopulation (adults coming from larvae recovered by interruption of competition) vary with time as regards frequency-dependence; and (4) the wild type strain Oregon is the active agent in competition with the strain …
Organophosphonate utilization by the wild‐type strain of cladosporium resinae
1997
We studied the biodegradation of compounds containing phosphorus‐to‐carbon bond by using wild‐type strain of Cladosporium resinae. The substrate specificity of the strain was studied and we found that it is able to utilize a range of structurally diverse organophosphonates as a sole source of phosphorus. This ability is inducible as indicated by the presence of a lag phase of the growth. A popular herbicide glyphosate is also degraded by the fungi. This indicates that Cladosporium resinae may play an important role in biodegradation of this herbicide. The strain which we used, however, did not metabolise any phosphonates when they served as the sole carbon or nitrogen sources.
