The sex-limited "alba" genetic polymorphism in wing color of Colias butterflies has been studied with respect to potential selective pressures on this locus. Alba female pupae, carrying at least one dominant A allele, redirect resources, used by aa pupae for pigmentation, to other metabolic ends. Associated with this reallocation, alba, A-, female adults eclose earlier, retain more larva-derive...

The role of Cl(-) in photosynthetic O(2) evolution has been investigated by observing the (35)Cl NMR linewidth under a variety of conditions in aqueous suspensions of chloroplasts, primarily for the halophytes Avicennia germinans, Avicennia marina, and Aster tripolium but also for spinach. The line broadening shows there is weak, ionic binding of Cl(-) to thylakoids, the bound Cl(-) exchanging ...

The breeding ecology of White and Japanese Wagtails, Motacilla alba and M . grandis, was studied along a river in central Japan. The home ranges of the two species greatly overlapped along the river, but no interbreeding occurred. M. grandis spent more time on the river than M . alba and defended territories there. M . alba used the river as part of the entire home range, and did not defend the...

BACKGROUND Morus alba has long been used in traditional Chinese medicine to treat inflammatory diseases; however, the scientific basis for such usage and the mechanism of action are not well understood. This study investigated the action of M. alba on leukocyte migration, one key step in inflammation. METHODS Gas chromatography-mass spectrometry (GC-MS) and cluster analyses of supercritical C...

UNLABELLED PREMISE OF THE STUDY Microsatellite markers were developed in the invasive species Bidens alba (Asteraceae) to assess its population structure and to facilitate tracking its expansion in China. • METHODS AND RESULTS Using 454 pyrosequencing, 20 microsatellite primer sets were developed for B. alba. The markers were tested on one population of B. alba (30 individuals) and one pop...

—Unsuccessful oak (Quercus spp.) regeneration could result in losses of the rarer portions of the midwestern North American oak savanna region, including the tall grass oak savannas. We undertook this study to understand the effects of restoration on promoting growth of naturally occurring Q. alba seedlings in a degraded tall grass oak savanna in Iowa, USA. Initial restoration efforts, which in...
