Most flowering plants need pollination to reproduce, which can be achieved through various pollinators. Some of the most widely known pollinators are bees and butterflies, but there are many other pollinators, including bats, lemurs, and even some reptiles. However, climate change threatens the relationship between plants and their pollinators in many ways.
Due to rising temperatures, blooming periods for some flowering plants have shifted. Flowers usually bloom based on temperature, light, and the seasons. But due to rising temperatures, these timing cues are changing which has led to early or late blooming for some plants. This can be a problem for pollinators, like bees, which may emerge too early in the season when flowers aren’t yet ready. Similarly, if flowers bloom too late, the pollinators may have already finished their life cycles for the season. This mismatch between when flowers bloom and when pollinators are active is called phenological mismatch. It refers to interacting species having different reactions to changes in their environment, such as climate change, and it makes it harder for plants to get pollinated. This means they may not be able to reproduce as effectively. Over time, this can lead to fewer plants growing, which can ultimately affect entire ecosystems.
In addition to changing weather patterns, extreme weather events like heatwaves, droughts, and storms also hurt both plants and pollinators.. Monarch butterflies experienced a die-out rate of over 50% in 2023 due to heavy rain and wind. Bees and other insects are especially vulnerable to high temperatures and dehydration, which can reduce their numbers and their ability to pollinate effectively. Habitat loss is another issue. As cities expand and forests are cut down, pollinators lose their homes and places to forage for food. When you combine habitat loss with the effects of climate change, it becomes even harder for pollinators to survive.
The impact of these changes goes beyond plants and pollinators. Humans depend on pollinators for many of the foods we eat, like fruits, vegetables, and nuts. If pollinators decline, crop yields could decline, leading to even higher food prices and food scarcity. This would be a serious problem for global food security. To protect pollinators and the plants they help grow, we need to take action. Restoring habitats, creating spaces that are friendly to pollinators, and reducing greenhouse gas emissions are all important steps to preserving the relationship between plants and their pollinators.
What a beautiful post. It’s amazing to see how such little creatures can have such a big impact on the world. It’s sad to see the effects of climate change damaging pollinators and plant growth.
ReplyDeleteGreat information, Kat! You explained the phenological mismatch really well I didn’t realize how much early blooming and pollinator timing could throw off entire ecosystems. The monarch die-off was especially shocking. Do you think enough is being done to restore pollinator habitats? Thanks for raising awareness about this important issue!
ReplyDeletePollinators are key part of any land ecosystem helping plants reproduce. Seeing their population decline is very scary seeing as they are a keystone species. Humans and wildlife are and will be affected by this.
ReplyDeleteAgreed, it is a fast decline, 50% of monarchs in just 2023 was sad to hear.
DeleteI have never heard of a phenological mismatch so this was interesting and informative, thank you for sharing.
ReplyDeleteIt is sad to see everything changes so much due to the impacts of humans. Looking back at phenological journals we sure can tell there has been a change!
ReplyDeleteWithout pollinators, our entire food system is at risk, especially for crops we often take for granted. Habitat restoration and pollinator-friendly spaces are practical and important steps that communities can take!
ReplyDeleteI've about this phenomenon before, but I hadn't yet seen the most recent numbers, and I must say they're rather bleak. Our ecosystems and our food supplies are at major risk if pollinator populations collapse.
ReplyDeleteI've also seen that shifting climate and weather patterns are pushing the spread of invasive species, because invasives are tolerant of a wider range of environmental conditions than the native species, and outcompete them as a result. Climate change impacts truly every aspect of our world, even the parts of it that are as small as hummingbirds and insects.
This broke my heart to read. My mom used to own beehives to help with pollination and we kept them for years. They are very intelligent animals but they can not compete with mankinds pollution and global warming. I didn't even consider other pollinators like butterflies and humming birds.
ReplyDeleteSince we are humans and tend to be very thoughtless of other living beings, we must remember we are all apart of nature (as much as we mess it up) The pollinators need to be protected
ReplyDeleteAs much as I am not a bee person, I know that they are one of the most important species on this earth. This is really sad knowing the impact on them from us. People hear climate change and think of melting ice or warmer weather, but no one thinks of the little bees. Great job!
ReplyDeleteI have known how important pollinators are for the plants and other flowers, but I forget that climate change is affecting their job if they are not on the same page.
ReplyDeleteI know pollinators are so important for our planet and especially flowers i couldn't help but think about the irony of it all flowers are meant to represent love in many cases and with our planet dying because of climate change. If we do nothing about it and the flowers die out then it shows our love for the planet died with them.

ReplyDeleteThis is very enlightening. A friend of mine had a project analyzing the blooming patterns of our maple trees on campus and found that despite it not blooming here in this part of Michigan, Michigan as a whole is experiencing signs of an early spring, which leaves plants at more of a risk for devastation if there are random frosts after they already have bloomed. If people can't open their eyes and see the small signs of climate change in their own backyard, it's going to be hard to convince them to demand change in a large scale.
ReplyDeleteIt's crucial to recognize the interconnectedness of climate change, plant-pollinator relationships, and food security, as protecting these vital ecosystems is essential for sustaining both biodiversity and our food supply.
ReplyDeleteThis is such an important topic to cover! Pollinator's are such an important part of every ecosystem, luckily supporting them here in Michigan is relatively achievable, even planting native flowers and certain plants on your property can make a big difference locally.
ReplyDeleteWhat are some ways that communities can better safeguard these important linkages by combining scientific research with grassroots conservation initiatives?
ReplyDeleteI have read a couple books recently about trees by Doug Tallamy - he is an insect expert and the books examine the rich and complex relationship between insects and trees. I had no idea how complex these relationships were, or how many species depended on each other.
ReplyDeleteThis is a fascinating post! I have even noticed in the past year or so that a lot of plants in my home garden have been blooming late, and it definitely draws concern. It is so important to consider these relationships even from the smallest species because they all play a role in healing our environment.
