Fecundity selection, acting on traits enhancing reproductive output, is an important determinant of organismal body size. Due to a unique mode of reproduction, mating success and fecundity are positively correlated with body size in both sexes of male-pregnant Syngnathus pipefish. As male pipefish brood eggs on their tail and egg production in females(More)
Amniote egg and eggshell morphology is a rich source of characters to link aspects of reproductive biology with systematics. Extensive work concerning both anatomy and phylogenetic assignability has been done on fossil bird and dinosaur eggs, but little is known for extant sauropsids. The utility of eggshell characters for phylogenetic analyses is tested(More)
The photoreversible metal-ion complexation behavior of nitroquinolinospiropyranindoline (NQSP) was studied in combination with the selective identification of six different transition-metal ions, Zn(2+), Co(2+), Hg(2+), Cu(2+), Cd(2+), and Ni(2+), in single- and binary-component mixtures via partial least squares discriminant (PLSD) analysis. The(More)
