They differ in that whereas the medial subdivision returns to its point of origin, HVC, the lateral one ends in RA. This way, the anterior pathway’s medial and lateral components could separately influence activity, and thus ZENK activation, in HVC and RA. Electrophysiological Relevance and ...
(including 0 days for unpaired males, which effectively forces the regression line through the origin). This also controls for variation in the duration of the breeding experiments. We also controlled for male inbreeding coefficient and adult sex ratio in the aviary by including these factors as...
The effect of the radical-pair decay rates on triplet yields has a twofold origin. For very high decay rates (>10 μs−1) the fast decay of the radical pair prevents efficient singlet-triplet mixing, as can be seen by the decrease of the triplet yields at zero magnetic field. For suc...
Stray birds of summer come to my window to sing and fly away. And yellow leaves of autumn, which have no songs, flutter and fall there with a sign. 2 世界上的一队小小的漂泊者呀,请留下你们的足印在我的文字里。 O Troupe of l...
The limits of a species’ distribution were mapped using known occurrences of the taxon, and knowledge of habitat preferences, elevation limits and so on. Standard data attributes on presence, origin and seasonality were recorded for each range polygon. There are 53 species in the GAA2 without ...
