Blackwood et al. (1) assert that terminal restriction fragment length polymorphism (T-RFLP) data cannot be used to estimate the species level diversity of bacterial communities. While I do not argue with their analytical techniques, nor the interpretation of their results, their conclusion is essentially moot as T-RFLP techniques are rarely used (nor should they be used) to study the diversity ...

A PCR-restriction fragment length polymorphism (RFLP) analysis method that analyzes a part of the dnaJ gene was designed for the rapid and accurate identification of Staphylococcus spp. XapI or Bsp143I digestion of the PCR-generated products rendered distinctive RFLP patterns that allowed 41 reference species and subspecies to be identified with a high degree of specificity. The novel method wa...

There is a significant relationship between the intestine length (Y) and total body length (X) for 11 species of freshwater fish (Y = 0.08X1.42). Sufficient variation exists about this relationship to indicate important differences among the species' diets. The diets for each species, ranked on a Trophic Index scale determined from literature data, are negatively rank order correlated with the ...

A new technique for determining carrier diffusion lengths in direct gap semiconductors by cathodoluminescence measurement is presented. Ambipolar diffusion lengths are determined for GaAs quantum well material, bulk GaAs, and AlzGa1-zAs with x up to 0.38. A large increase in the diffusion length is found as x approaches 0.38 and is attributed to an order of magnitude increase in lifetime.

This study was conducted to determine length-weight and length-length relationships, relative condition factor (Krel) and Fulton?s condition factor (K) for five species including Scardinius erythrophtalmus, Carassius auratus gibelio, Cyprinus carpio, Tinca tinca and Hemiculter leucisculus belonging to Cyprinidae family. Fish sampling was carried out by gill net and fyke net in the western regio...
