Searched ISI for climate-related literature
To review climatological and ecological approaches we initially searched for Topic: (phenolog*)
and at least one of Topic: (shoot elongation, temperature, precipitation, rain, daylength,
leafout, budburst, flower) which produced 551 records. However we then limited
our search to Topic: (temperature OR precipitation OR rain* OR
photoperiod* OR day length OR daylength) AND Topic: (phenolog* AND
climate) AND Topic: (leafout OR budburst OR flower* OR leafing OR
shoot elongation) because this gave a much higher return of records
related to cues. We reviewed all of these abstracts for which articles
included species-specific information on cues underlying phenological
events.
