altered development and life cycles- lqc 17a Flashcards
which environmental factor is most likely to effect animal species
temperature, acts as a cue or trigger for their development or behaviour
what is the other environmental cue for some species
photoperiod
what cue do some plants use
rainfall
why do animals and plants need to be synchronised with each other
the hatching of eggs or emergence of adults (after hibernation) is synchronised with periods of maximum food availability, a mismatch can result in seriously reduced survival rate
how is phenology used to provide evidence for climate change
the timing of developmental events are used as biological indicators, many long term records exist, many data sets from different species and locations are needed, they are compared and tested statistically to improve validity
