Human perception of non-native sound contrasts are strongly influenced by their native (L1) phonological system (Best 1995; Flege 1995). For example, it has been well documented that Japanese speakers have difficulties discriminating English /r/ and /l/ (Goto 1971, Lively, Pisoni, Yamada, Tohkura & Yamada 1994). Likewise, English speakers have difficulty in discerning the difference between the...

Photoperiodic control of flowering in the short day plant Perilla involves the transmission of a floral stimulus from induced leaves to the shoot apex. We have studied the basipetal movement of this stimulus and of (14)C-labeled assimilates in plants with an induced leaf (donor) grafted into the uppermost internode of a vegetative plant in which the axillary shoots at various nodes along the st...

Land surfaces are characterised by strong heterogeneities of soil texture, orography, land cover, moisture, snow, and other variables. The complexity the surface properties is very challenging to represent accurately in radiative transfer models, which have a limited reliability over land, especially for observations such as given. This has resulted difficulties assimilating land-surface relate...
