    Notes: [Auszug] A limit of winter cold will obviously operate on a plant in a different way from a limit of July heat; and four possible sorts of temperature limits have been quoted above for particular cases. It could be supposed that for each plant species there may be, in broad terms, an optimum summer ...

    Notes: [Auszug] I have now found that if the areas between January isotherms for 27 F. and 54 F. actual temperatures in the northern hemisphere are shaded, upon a map of the world, and areas between July isotherms for 51 F. and 66 F. are shaded the other way upon the map, the two sets of shadings are found in ...

    Notes: Abstract  This paper examines the mean flowering times of 11 plant species in the British Isles over a 58-year period, and the flowering times of a further 13 (and leafing time of an additional 1) for a reduced period of 20 years. Timings were compared to Central England temperatures and all 25 phenological events were significantly related (P〈0.001 in all but 1 case) to temperature. These findings are discussed in relation to other published work. The conclusions drawn from this work are that timings of spring and summer species will get progressively earlier as the climate warms, but that the lower limit for a flowering date is probably best determined by examining species phenology at the southern limit of their distribution.
