...Daniel L. Clark; Mark E. Hauber; Philip S. L. Anderson ABSTRACT Some host species of avian obligate brood parasites reject parasitic eggs from their nest whereas others accept them, even though they recognize them as foreign. One hypothesis to explain this seemingly maladaptive behavior is that...

...Francois Criscuolo; Roxanna Torres; Sandrine Zahn; Tony D. Williams ABSTRACT Avian eggs contain a large number of molecules deposited by the mother that provide the embryo with energy but also potentially influence its development via the effects of maternally derived hormones and antibodies: the...

... tested electroglottography (EGG) as a novel tool for examining vocal fold kinematics in the avian vocal organ, the syrinx. We furthermore imaged and quantified syringeal kinematics in the pigeon ( Columba livia ) syrinx with unprecedented detail. Our results show that EGG signals predict (1) the relative...

...Daniel Kiefer; Elizabeth M. Warburton; Irina S. Khokhlova; Boris R. Krasnov ABSTRACT To test relationships between maternal size, egg size and size of new offspring, we studied (a) the effect of maternal size on egg size and number, and maternal survival after oviposition and (b) the effect of egg...

...Patrick J. Krug; Jeffrey A. Riffell; Richard K. Zimmer SUMMARY Red abalone ( Haliotis rufescens ) sperm detect a waterborne chemical cue released by conspecific eggs, and change their swimming behavior to increase the likelihood of fertilization success. Previously, we isolated the natural sperm...

... fertilized eggs and on the clotting reaction of hypotonically stressed coelomocytes. In suspensions of fertilized eggs to which Hsc70 or a 2:3 mixture of Hsc and Hsp70 was added, progression to the first mitotic division was accelerated. Evidence is provided that the extracellular Hsc70 passes into the egg...

... whether survival, development time and metabolism of eggs of a moth, Manduca sexta , were sensitive to experimentally imposed variation in atmospheric oxygen availability(5–50 kPa; normoxia at sea level is 21 kPa) across a range of biologically realistic temperatures. Temperature–oxygen interactions were...

...Edward M. Dzialowski; Paul R. Sotherland SUMMARY Parental investment in eggs and, consequently, in offspring can profoundly influence the phenotype, survival and ultimately evolutionary fitness of an organism. Avian eggs are excellent model systems to examine maternal allocation of energy...

...James T. Pearson; Roger S. Seymour; Russell V. Baudinette; Susan Runciman SUMMARY We examined whether the previously reported low cost of embryonic development in pelicans could be attributed to a more efficient conversion of egg energy to hatchling tissues as a result of high initial egg water...

...Jeffrey A. Riffell; Patrick J. Krug; Richard K. Zimmer SUMMARY Chemical communication between sperm and egg is a key factor mediating sexual reproduction. Dissolved signal molecules that cause sperm to orient and accelerate towards an egg could play pivotal roles in fertilization success,but such...
