Thirty-two weeds commonly found in the organic soils of southwestern Quebec were evaluated for host suitability to a local isolate of the northern root-knot nematode Meloidogyne hapla under greenhouse conditions. Galls were observed on the roots of 21 species. Sixteen of the 21 had a reproduction factor (Pf/Pi = final number of M. hapla eggs and juveniles per initial number of M. hapla juvenile...

Melon (Cucumis melo L.) is a phenotypically diverse eudicot diploid (2n = 2x = 24) has climacteric and non-climacteric morphotypes and show wide variation for fruit firmness, an important trait for transportation and shelf life. We generated 13,789 SNP markers using genotyping-by-sequencing (GBS) and anchored them to chromosomes to understand genome-wide fixation indices (Fst) between various m...

Cyclic vole populations, defined as showing fairly regular 3 /4 yr density fluctuations but with variable amplitudes, were monitored in boreal Sweden in spring and fall 1971 /2002, starting in fall 1971. Voles were snap-trapped on permanent sampling plots at the landscape level within a 100 by 100 km study area north of Umeå. The predominating species trapped were Clethrionomys glareolus, C. ru...

Live trapping is central to the study of small mammals. Thus, any bias needs to be understood and accounted for in subsequent analyses to ensure accurate population estimates. One rarely considered bias is the behavioural response of individuals to the trap, in particular the olfactory cues left behind by previous occupants (PO). We used a data set of 8,115 trap nights spanning 17 separate trap...

Fadogia cienkowskii is a shrub whose roots are used in many communities of Northern Nigeria to improve sexual performance; however, there no scientific study verify this claim. This determined the effect 70% ethanol extract F. and its fractions (ethyl acetate, n-butanol, residual ethanol) on mating behaviour (mounting, intromission ejaculation) serum testosterone concentration male albino rats....
