10 Most Bizarre Ways Nature Finds Love in the Wild
So you think you’ve had some strange dates? This Valentine’s Day, The Nature Conservancy compiled the top 10 most bizarre examples of love in the wild.
“Nature can get pretty wild, especially when love is in the air,” said Terry Sullivan, director of The Nature Conservancy in New Mexico.
Unfortunately, many of these creatures are at risk of disappearing forever because of habitat loss, climate change, and other threats.
“Here in New Mexico, the lesser prairie chicken faces an uncertain future because of loss of habitat,” said Tish McDaniel, southern short grass project director for New Mexico’s Conservancy. “As much as 90 percent of the lesser’s habitat has been lost due to fragmentation. We are out of balance.”
The lesser prairie chicken is renowned for the extraordinary dance that it performs as part of its mating ritual. To make sure these incredible animals survive in the future, The Nature Conservancy is protecting habitat on the Milnesand Prairie Preserve, the heart of the prairie chicken population. We also collaborate with partners, including landowners, ranchers and farmers, to access funding for habitat restoration projects. Plus, the conservancy, in concert with others, is restoring abandoned oil and gas roads and removing invasive shrubs and non-native trees.
“Nature is powerful, but for many animals their future depends not only on their mating prowess but on what help we give them,” McDaniel added. “If we don’t act now to protect the lands these iconic creatures call home, they may not be around for future generations to witness their spectacular mating dances.”
In an effort to raise awareness about the importance of protecting prairie chickens, the conservancy partners with the community of Milnesand, the New Mexico Department of Game and Fish Department and Grasslands Charitable Foundation for the 11th Annual High Plains Prairie Chicken Festival on April 20-22.
In addition to the incredible displays of our own lesser prairie chicken, here are 10 other bizarre mating practices from around the planet:
1) Deep sea angler fish—“Losing yourself in love”
Male anglerfish bite their mates and permanently fuse to their bodies. Over time, the male’s brain, eyes and organs dissolve until he turns into a small lump, releasing sperm whenever the female is ready to lay eggs. Scientists first thought the lumps were fins before discovering they were the males.
2) Prairie Chickens—“Strut Your Stuff”
Male prairie chickens attract females with loud “booming” noises that can be heard miles away. They also perform an elaborate dance—lowering their heads, erecting their neck feathers, inflating orange air sacks, dropping their wings and pointing their tails, all while frantically stamping their feet.
3) American Burying Beetle—“Family Oriented”
American burying beetles not only are monogamous but also raise their children together. Expectant parents bury dead birds or mice and lay eggs nearby. The parents lie on their backs and use their legs like a conveyor belt to move carcasses up to 200 times their own weight. Once hatched, larvae feed on the carcass or the parents rub their wings together to call the larvae and regurgitate meat into their mouths.
4) Freshwater mussels—“The bait and switch”
Male mussels release sperm into the water, which females capture downstream. Larvae hatch inside the females’ shells but must then attach to a fish to grow. To lure fish, mother mussels wave appendages that look like worms, crayfish or other bait. Some emit a smell of rotting flesh to attract scavenger fish. When fish approach, the mussels shoot the larvae onto the fish.
5) Prairie Vole—“Born to be Faithful”
Unlike most rodents, prairie voles are monogamous. Scientists have discovered that prairie vole faithfulness is caused by hormone receptors located in their brain’s reward centers, giving them the sense of pleasure from monogamy.
6) Bower birds—“Bachelor Pads”
Male bowers of Australia and New Guinea build large and elaborate bachelor pads on forest floors, decorated with flowers, leaves, shells and even stolen coins—anything they think will attract a mate. Some paint the walls with chewed berries, others build lawns of moss. Drab males build the flashiest pads to compensate for their dull colors.
7) Lions—“One Track Mind”
When lions mate, the coupling usually lasts only about 20 seconds. But the pair will repeat the act every 20 minutes or so—sometimes up to 40 times a day. This will continue for three to seven days straight, with the male and female neglecting to hunt or eat during the entire time.
8) Tree crickets—“Smooth talker”
Male crickets bite holes in leafs to amplifier their love songs and attract females. Once they mate, however, male sperm packets don’t fit inside the females’ bodies so a portion hangs out. The ever-ravenous females try to eat the packet before fertilization can occur. To distract her, the male sings and secretes a tasty goo from his back, feeding her until the eggs are fertilized.
9) Day Octopus—“Keep Your Distance”
Female day octopi are known to eat their partners after mating, so the males keep their distance. When a male finds a female, he extends one arm and waves. If she responds, he uses his arm to place a sperm packet under the female’s body covering. The octopi stay at an arm’s length—appearing as though they are holding hands.
10) Little Brown Bats—“Waiting for the Right Time”
Because these bats mate in the autumn—but hibernate during winter—females store sperm for seven months to delay pregnancy until springtime. While bats normally hang upside down, females stand upright to give birth and catch their babies in a membrane between their legs. Newborns cling to their mothers even during nighttime flights as they search for food.

One of nature's epic events is underway: Monarch butterflies' fall migration. Departing from all across the United States and Canada, the butterflies travel up to 2,500 miles to cluster at the same locations in Mexico or along the Pacific Coast where their great-grandparents spent the previous winter.
Millions of People Care About Monarchs<p>I will never forget the sights and sounds the first time I visited monarchs' overwintering sites in Mexico. Our guide pointed in the distance to what looked like hanging branches covered with dead leaves. But then I saw the leaves flash orange every so often, revealing what were actually thousands of tightly packed butterflies. The monarchs made their most striking sounds in the Sun, when they burst from the trees in massive fluttering plumes or landed on the ground in the tussle of mating.</p><p>Decades of educational outreach by teachers, researchers and hobbyists has cultivated a generation of monarch admirers who want to help preserve this phenomenon. This global network has helped restore not only monarchs' summer breeding habitat by planting milkweed, but also general pollinator habitat by planting nectaring flowers across North America.</p><p>Scientists have calculated that restoring the monarch population to a stable level of about 120 million butterflies will require <a href="https://doi.org/10.1111/icad.12198" target="_blank">planting 1.6 billion new milkweed stems</a>. And they need them fast. This is too large a target to achieve through grassroots efforts alone. A <a href="https://www.fws.gov/savethemonarch/CCAA.html" target="_blank" rel="noopener noreferrer">new plan</a>, announced in the spring of 2020, is designed to help fill the gap.</p>
Pros and Cons of Regulation<p>The top-down strategy for saving monarchs gained energy in 2014, when the U.S. Fish and Wildlife Service <a href="https://www.fws.gov/southeast/pdf/petition/monarch.pdf" target="_blank">proposed</a> listing them as threatened under the Endangered Species Act. A decision is expected in December 2020.</p><p>Listing a species as endangered or threatened <a href="https://www.fws.gov/endangered/esa-library/pdf/listing.pdf" target="_blank">triggers restrictions</a> on "taking" (hunting, collecting or killing), transporting or selling it, and on activities that negatively affect its habitat. Listing monarchs would impose restrictions on landowners in areas where monarchs are found, over vast swaths of land in the U.S.</p><p>In my opinion, this is not a reason to avoid a listing. However, a "threatened" listing might inadvertently threaten one of the best conservation tools that we have: public education.</p><p>It would severely restrict common practices, such as rearing monarchs in classrooms and back yards, as well as scientific research. Anyone who wants to take monarchs and milkweed for these purposes would have to apply for special permits. But these efforts have had a multigenerational educational impact, and they should be protected. Few public campaigns have been more successful at raising awareness of conservation issues.</p>
<span style="display:block;position:relative;padding-top:56.25%;" class="rm-shortcode" data-rm-shortcode-id="91165203d4ec0efc30e4632a00fdf57d"><iframe lazy-loadable="true" src="https://www.youtube.com/embed/KilPRvjbMrA?rel=0" width="100%" height="auto" frameborder="0" scrolling="no" style="position:absolute;top:0;left:0;width:100%;height:100%;"></iframe></span>
The Rescue Attempt<p>To preempt the need for this kind of regulation, the U.S. Fish and Wildlife Service approved a <a href="https://www.fws.gov/savethemonarch/pdfs/Monarch%20CCAA-CCA%20Public%20Comment%20Documents/Monarch-Nationwide_CCAA-CCA_Draft.pdf" target="_blank">Nationwide Candidate Conservation Agreement for Monarch Butterflies</a>. Under this plan, "rights-of-way" landowners – energy and transportation companies and private owners – commit to restoring and creating millions of acres of pollinator habitat that have been decimated by land development and herbicide use in the past half-century.</p><p>The agreement was spearheaded by the <a href="http://rightofway.erc.uic.edu/" target="_blank">Rights-of-Way Habitat Working Group</a>, a collaboration between the University of Illinois Chicago's <a href="https://erc.uic.edu/" target="_blank" rel="noopener noreferrer">Energy Resources Center</a>, the Fish and Wildlife Service and over 40 organizations from the energy and transportation sectors. These sectors control "rights-of-way" corridors such as lands near power lines, oil pipelines, railroad tracks and interstates, all valuable to monarch habitat restoration.</p><p>Under the plan, partners voluntarily agree to commit a percentage of their land to host protected monarch habitat. In exchange, general operations on their land that might directly harm monarchs or destroy milkweed will not be subject to the enhanced regulation of the Endangered Species Act – protection that would last for 25 years if monarchs are listed as threatened. The agreement is expected to create up to 2.3 million acres of new protected habitat, which ideally would avoid the need for a "threatened" listing.</p>
A Model for Collaboration<p>This agreement could be one of the few specific interventions that is big enough to allow researchers to quantify its impact on the size of the monarch population. Even if the agreement produces only 20% of its 2.3 million acre goal, this would still yield nearly half a million acres of new protected habitat. This would provide a powerful test of the role of declining breeding and nectaring habitat compared to other challenges to monarchs, such as climate change or pollution.</p><p>Scientists hope that data from this agreement will be made publicly available, like projects in the <a href="https://www.fws.gov/savethemonarch/MCD.html" target="_blank">Monarch Conservation Database</a>, which has tracked smaller on-the-ground conservation efforts since 2014. With this information we can continue to develop powerful new models with better accuracy for determining how different habitat factors, such as the number of milkweed stems or nectaring flowers on a landscape scale, affect the monarch population.</p><p>North America's monarch butterfly migration is one of the most awe-inspiring feats in the natural world. If this rescue plan succeeds, it could become a model for bridging different interests to achieve a common conservation goal.</p>

The annual Ig Nobel prizes were awarded Thursday by the science humor magazine Annals of Improbable Research for scientific experiments that seem somewhat absurd, but are also thought-provoking. This was the 30th year the awards have been presented, but the first time they were not presented at Harvard University. Instead, they were delivered in a 75-minute pre-recorded ceremony.

For decades, climate scientist David Keith of Harvard University has been trying to get people to take his research seriously. He's a pioneer in the field of geoengineering, which aims to combat climate change through a range of technological fixes. Over the years, ideas have included sprinkling iron in the ocean to stimulate plankton to suck up more carbon from the atmosphere or capturing carbon straight out of the air.
Solar geoengineering would involve injecting reflective aerosols from high-altitude planes into the layer of the upper atmosphere known as the stratosphere, which stretches between 10 to 50 kilometers (6 to 31 miles) above Earth's surface. The idea is that the aerosol particles would reflect a small amount of sunlight away from the planet, reducing the amount of heat trapped by greenhouse gases and mitigating some of the effects of climate change.
The planned Stratospheric Controlled Perturbation Experiment will send a balloon carrying scientific instruments in a gondola into the stratosphere. The instruments will release a small amount of material — likely ice or mineral dust — to form a kilometer-long plume of aerosol particles (left). Modified airboat propellers will allow the gondola to maneuver above the plume (middle) and lower instruments into the plume to take repeated measurements of how the particles spread through the stratosphere (right). ADAPTED FROM J.A. DYKEMA ET AL / PHILOSOPHICAL TRANSACTIONS OF THE ROYAL SOCIETY A 2014
David Keith envisions using multiple approaches to combat climate change. The red line shows how the impacts of climate change would worsen with a business-as-usual scenario of unabated burning of fossil fuels and other greenhouse gas emissions. Aggressively cutting emissions bends that curve, and removing carbon from the atmosphere offers further cuts, but there are still consequences from the already high levels of carbon dioxide. In this scenario, solar geoengineering would lessen the impact from existing atmospheric carbon dioxide, effectively carving the top off the curve.<p>Some people think we should use it only as a get-out-of-jail card in an emergency. Some people think we should use it to quickly try to get back to a preindustrial climate. I'm arguing we use solar geoengineering to cut the top off the curve by gradually starting it and gradually ending it.</p><p><strong>Do you feel optimistic about the chances that solar geoengineering will happen and can make a difference in the climate crisis?</strong></p><p>I'm not all that optimistic right now because we seem to be so much further away from an international environment that's going to allow sensible policy. And that's not just in the US. It's a whole bunch of European countries with more populist regimes. It's Brazil. It's the more authoritarian India and China. It's a more nationalistic world, right? It's a little hard to see a global, coordinated effort in the near term. But I hope those things will change.</p>
