The rapidly increasing rate of urbanization has a major impact on the ecology and evolution of species. While increased temperatures are a key aspect of urbanization ("urban heat islands"), we have very limited knowledge whether this generates differentiation in thermal responses between rural and urban populations. In a common garden experiment, we compared the thermal performance curves (TPCs...

polyphenol oxidase (ppo) activity varied in differentiation from hyphae to rhizomorph and croute in a. mellea. in undifferentiated hyphae there was not any ppo activity, while croute showed the highest activity. electrophoresis in the presence of sds allows the detection of intensive enzyme forms of ppo, and can also convert slower migrating enzyme forms to faster ones. some fluorescent compoun...

this paper establishes new support for implementing outward oriented trade policies by relating industrial sector growth, trade policy orientation and export growth in 36 developing countries,including iran using a logistic growth function. based on thisstudy the use of stronglyoutward oriented policies towards export is likly relatedto a faster growth ofthe share of industrial output in gdp as...

BACKGROUND The light-emitting Vibrios provide excellent material for studying the interaction of cellular communication with growth rate because bioluminescence is a convenient marker for quorum sensing. However, the use of bioluminescence as a marker is complicated because bioluminescence itself may affect growth rate, e.g. by diverting energy. METHODOLOGY/PRINCIPAL FINDINGS The marker effec...

T  his study aimed to examine the relationship between food security, health and economic growth. These three components together form the vertices of a triangle. How much does food security strategies in a country bring more health to its people? Is the  healthy population richer? What is the impact of health on income, and to what extent are income variation am...
