BACKGROUND Adolescent girls continue to fall victim to unintended pregnancy and its consequences, with particular problems arising in low income countries. Awareness about methods of contraception is an important step towards gaining access and using suitable contraceptive methods. However, studies assessing the relationship between sexual and reproductive health communication and awareness of ...

Few data are available on the effectiveness of reproductive isolating mechanisms in externally fertilizing taxa. I investigated patterns of conspecific and heterospecific fertilization among three coexisting sea urchin species, Strongylocentrotus droebachiensis, S.franciscanus, and S. purpuratus. In the laboratory, both among and within species, eggs from individual females whose eggs are more ...

One fundamental signature of reinforcement is elevated prezygotic reproductive isolation between related species in sympatry relative to allopatry. However, this alone is inadequate evidence for reinforcement, as traits conferring reproductive isolation can occur as a by-product of other forces. We conducted crosses between Silene latifolia and S. diclinis, two closely related dioecious floweri...

Streptococcus equi subsp. zooepidemicus is the pathogen most commonly isolated from the uterus of mares. S. zooepidemicus is an opportunistic pathogen and part of the resident flora in the caudal reproductive tract. The aim of this study was to investigate whether a genotypically distinct subpopulation of S. zooepidemicus is associated with endometritis in the mare, by genotyping and comparing ...

Sorghum halepense (L.) Pers. is a troublesome weed of maize which reproduces through seeds and rhizomes. Resistance to ACCase-inhibiting herbicides due target-site mutation Ile-Asn in position 2041 the ACCase gene was confirmed several populations Italy. The presence fitness costs related allelic variant Ile2041Asn has never been investigated ACCase-resistant S. . Three growth analyses pot expe...

DESIGN Review. SETTING None. PATIENT(S) None. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) None. RESULT(S) None. CONCLUSION(S) A help-seeking model provides a plausible explanation...

Multiple mechanisms of resistance to glyphosate are exhibited by populations of Lolium spp. worldwide. Association of resistance with growth and reproductive fitness is an important predictor for long-term success of glyphosate-resistant (R) versus glyphosate-susceptible (S) biotypes. Numerous studies were conducted on R- and S-biotypes of Italian ryegrass (Lolium multiflorum) and perennial rye...
