Bee pollinators are an essential part of global food production and ecological balance, but their populations are declining. The reasons for this decline are complex and involve human activities. In Europe, for example, over 30% of bee species are threatened with extinction. The decline in bee populations can be attributed to insecticides, changes in soil quality, agriculture practices, and changes in climate, among other factors. However, new research shows that some species of wild flowers are adapting to the lack of bee pollinators by relying on their own seeds. The Viola arvensis, a common wild flower in Europe, has been observed to produce smaller flowers with less nectar in response to the lack of bee pollinators. This adaptation allows the plant to reproduce, but it also has consequences for the plant's ability to attract bees in the future. Some scientists believe that these plants may eventually lose their ability to reproduce with bee pollinators. However, it is also possible that these plants may be able to recover their ability to reproduce with bees if bee populations recover. But the question remains, how will these plants survive in the meantime? The study of autopolinization, or the ability of plants to reproduce without the help of pollinators, offers some insights into this question. For example, researchers have found that the autofecundation rate of Viola arvensis has increased by 27% since the 1990s. This finding suggests that some plants may be able to adapt to the lack of bee pollinators by relying on their own seeds. However, there are also limitations to this approach. Autopolinization can reduce the genetic diversity of plant populations, which can be a risk for the long-term survival of these plants. The future of bee pollinators and the plants that depend on them is uncertain, but ongoing research offers new insights into the complex circular problem of declining bee populations and the adaptation of plants to a changing world.

In growing #plants from various salinity #habitats, we found evidence for local #plantSalinity adaptation only when plants were provided with #microbes. Microbial interactions may therefore mediate patterns of #plantAdaptation as well as be important selective agents on the plant.
