Specifically, higher autumn temperatures in the Northeastern United States is delaying the color change. [27] Experiments with poplar trees showed that they stayed greener longer with higher CO 2 levels, independent of temperature changes. [26] However, the experiments over two years were too brief to indicate how mature forests may be affected ...
Throughout much of its range this species is in decline. Modelling of Aloidendron dichotomum in South Africa and Namibia has contributed to understanding the needs of protected areas in response to climate change. Modelled range declines in this species due to climate change have recently been confirmed by field surveys. [6]
Distributions of species and plant species will narrow following the effects of climate change. [11] Climate change can affect areas such as wintering and breeding grounds to birds. Migratory birds use wintering and breeding grounds as a place to feed and recharge after migrating for long hours. [24] If these areas are damaged due to climate ...

Floral color change can also be a result of an increase or decrease in pH. Hydrangea is a model genus for this particular chemical change in flowers. Floral pigments in Hydrangea are affected by the presence of aluminum ions in the soil, causing changes in flower color from red, pink, blue, light purple or dark purple.
[11] [12] The colors of the bracts are created through photoperiodism, meaning that they require darkness (at least fourteen hours at a time for 6–8 weeks in a row) to change color. The plants also require abundant light during the day for the brightest color. [13] Semi-evergreen, they generally lose most of their leaves during winter. [14]
Climate change may threaten saguaros and their ecosystems, as deserts are particularly susceptible to climate effects. Rising daytime and nighttime temperatures will reduce the water use efficiency of saguaros, forcing them to use more water and making them more likely to die during drought periods.
