A sustainable life is based on the ecosystem’s interaction between plants and

animals. Nectar release is one of the important interaction mechanisms developed

by plants in terms of nutrition and reproduction. Nectar is secreted

from nectariums that are floral or extrafloral in angiosperms. Although it varies

according to the plant type, nectar generally contains water, carbohydrates

(sucrose, glucose, fructose, maltose), oil, organic acids, aromatic substances,

amino acids, yeast, nitrogenous compounds, vitamins, and mineral

substances. Nectar has been a source of attraction for insects (bees, butterflies,

flies, ants), birds, and bats because of its components in many plants’ pollination

and fertilization mechanisms. It also plays an important role in increasing

biodiversity in the ecosystem by mediating cross-pollination. However,

in recent decades, the effects of climate change, the main reason for which is

global warming, have been felt. According to the Intergovernmental Panel on

Climate Change (IPCC), climate change is defined as “any change in climate

over time, whether due to natural variability or as a result of human activity”.

Observational evidence indicates that many ecosystems are affected by regional

and global climate changes, particularly temperature increases (IPCC

2007). Drought and higher temperatures caused by these changes in climate

are common stress conditions that are effective in plant growth and development.

The temperature increase can have a very different effect depending

on the location of the plants, geographical features, and climate diversity. It

can make changes in the anatomical and morphological features of the plant.

With an increase in temperature, water scarcity, and a decrease in groundwater,

nectar release may decrease, and changes in nectar concentration may be

observed. Based on the decrease in nectar secretion, problems in the flower

structure of the plant, the number of flowers, and the pollinator-flower harmony

may be the result of global warming. With an increase in temperature,

nectar release may increase in some species while decreasing in others

Nectar is very important not only because it contributes to biodiversity but

also as a food source for various living things. Therefore, the effects of nectar

release and global warming are discussed in the study. As a result, detailed

studies should be conducted on the effects of global warming and climate

change on nectar release. Multidisciplinary studies should be considered and

evaluated in research.
