Changes in Tree Phenology: an Indicator of Spring Warming in Ireland?

Biology & Environment: Proceedings of the Royal Irish Academy, 2006
Recent climate warming has been observed at the global scale, but by examining developmental stages of plant species (phenology) that are dependent on local climatic conditions, climate change at the local scale can be detected. There are four gardens in Ireland belonging to the International Phenological Gardens (IPG) network, which has recorded tree ...

Phenology of Spring Weeds in Norman, Oklahoma

The Southwestern Naturalist, 1956
Weed calendars were kept for January-May 1954 and 1955, involving 75 species, more than half native. Details are given for the 25 most abundant. Percentage of those initiating flowering reached a peak in April; of those actually in bloom, about mid-May.

Climate-associated changes in spring plant phenology in China

International Journal of Biometeorology, 2011
The timing of phenological events is highly responsive to global environmental change, and shifts in a phenological phase can affect terrestrial ecosystems, agriculture and economics. We analyzed changes in phenology for the spring season in China that occurred between the 1960's and the 2000's using four methods: species-level observations, meta ...

Effects of Microclimate on Spring Flowering Phenology

Ecology, 1966
Sixteen microclimatic stations with differences in slope, exposure, vegetation cover, and seasonal change were established in a heavily dissected 180—acre Indiana tract. Correlations, based on cumulative air temperature duration—summations, were made between microclimatic differences and variation in phenological events.

Environmental phenology drives spring migration timing

Journal of Animal Ecology
Abstract Despite the obvious shift in spring bird migration to earlier dates, the mechanism behind this process remains unclear, partly due to inappropriate climate predictors.

Spring Phenology Models for Temperate Apple Cultivars

The annual dormancy cycle of apple trees is highly temperature dependent, with photoperiod deemed irrelevant for dormancy induction or breaking. In fall, cold days induce endodormancy. Endodormancy, in turn, is overcome by further accumulation of chill, when a cultivar-specific chill requirement is met.
