EARLY-LIFE BEGGING EFFORT REDUCES ADULT BODY MASS BUT STRENGTHENS BEHAVIOURAL DEFENCE OF THE RATE OF ENERGY INTAKE IN EUROPEAN STARLINGS

Early-life begging effort reduces adult body mass but strengthens behavioural defence of the rate of energy intake in European starlings

Animals require strategies for coping with periods when food is scarce.Such strategies include storing fat as a buffer, and defending the rate of energy intake by changing foraging behaviour when food becomes difficult to obtain.Storage and behavioural defence may constitute alternative strategies for solving the same tanguray covington problem.We

Synthesis, Characterization and Primary Antimicrobial, Antifungal Activity Evaluation of Schiff bases of 4-Chloro-(3-substituted-phenylimino) - methyl-[2H] - chromene-2-one

Coumarins show promising antimicrobial and antifungal activity, this prompted to us to synthesize new derivatives of coumarins.4-Chloro-2-oxo-2H-chromene-3-carbaldehyde was reacted with substituted aniline and rectified spirit to obtain a new series of Schiff bases of 4-chloro-(3-substituted-phenylimino) -methyl- [2H]-chromene-2-one (3a-i).Their st
