Even after years of study, the California condor is still surprising researchers. Recently, two of the giant birds were discovered to have been born through parthenogenesis, a form of reproduction in which an unfertilized egg still hatches. Parthenogenesis is a type of asexual reproduction. Human beings and almost all other animals reproduce sexually, through mating between a male and a female. In asexual reproduction, a new organism (living thing) develops from parts of, or parts produced by, one organism. This example of parthenogenesis is particularly noteworthy because the condor is a critically endangered species. At its lowest population in 1982, only around 20 California condors were alive, in the wild and in captivity.

In 1982, researchers launched a program to save the condors, and over the next few decades, the population grew to over 500. The researchers also studied the condors in captivity. They were able to collect DNA samples from feathers and eggshells and could pay close attention to the birds’ reproductive habits. They discovered that two of the male condors did not have any genetic indication of having been fathered by the other condors in captivity. Despite having only one parent, the condors were not clones (genetically identical copies) of the mother. Rather, through fusion between the unfertilized egg and another reproductive cell in the mother’s body, the offspring end up with a unique mixture of the mother’s genetic material. Female condors can only produce male offspring through parthenogenesis, due to the way sex is determined by chromosomes among birds.

While parthenogenesis is fairly rare, it is not unheard of, even in birds. Some species of turkey and domestic pigeons also have been known to reproduce in this way. Additionally, birds are far from the only animals that can undergo parthenogenesis. Parthenogenesis has been seen in species of sharks—including the hammerhead and bamboo shark—as well as some species of snakes and lizards. Some insects, like aphids and stick insects, can also reproduce asexually. However, parthenogenesis has not been documented in mammals.

Most scientists thought that parthenogenesis only happened in populations that lacked males. For example, a female shark recently surprisingly gave birth after living 10 years in an Italian aquarium where no male sharks were kept. But the female condors had males in captivity with them. Other female condors nested and produced chicks after mating with the local males.

California condors are the largest flying land birds in North America, with a wingspan of 8 to 9 1/2 feet (2.4 to 2.9 meters). They weigh up to 23 pounds (10.4 kilograms). In the wild, condors spend much of the day resting on high perches. Condors do not build nests. Instead, their eggs are laid in caves, in holes, or among boulders. A female California condor lays just one egg every two years. Condors are powerful, graceful fliers. They can soar and glide for long distances, flapping their wings an average of only once an hour. They may search the ground for food as they fly. Like other vultures, condors eat the remains of dead animals.

The growth of urban areas has posed a major threat to condor survival. The condor’s way of life requires vast areas of open, hilly country, and urban growth destroys such habitat.

Tired Elk Relieved

School, homework, canceled activities, and retail shortages may have you feeling tired. But wildlife officials in October reached out to help an elk that was literally tired—the elk had spent two years with a tire stuck around its neck.

 

The bull (male) elk got a real weight off his shoulders on Oct. 9, 2021, when Colorado Parks and Wildlife officers removed the tire from around his neck. The oddly accessorized elk was originally spotted in July 2019 by a wildlife officer conducting a count of bighorn sheep and mountain goats in Mount Evans Wilderness. The Mount Evans Wilderness covers some 74,401 acres (30,109 hectares) of woods about 40 miles (64 kilometers) west of Denver. Officials had made four attempts to remove the tire over the previous week but were unsuccessful.

 

Officers do not know how the elk got the tire stuck on his neck. In Colorado, wildlife officials tranquilize about ten bull elk and buck (male) deer each year to remove objects from their necks. Many wild animals get stuck in basketball hoops, hammocks, buckets, laundry baskets, holiday decorations, and other objects. Wildlife officials asked residents of central Colorado to keep an eye out for the elk and to alert them to any sighting. There had been six sightings of the tired elk over the previous two years, mostly on trail cameras. Officials had been working tirelessly to locate and help this particular elk until resident Patrick Hemstreet reported the elk was in a herd of 40 just outside his house in Pine, Colorado. Hemstreet texted Dawson Swanson, a wildlife official who lives nearby.

 

The American elk is a large deer. The bull stands about 5 feet (1.5 meters) high at the shoulder and may weigh from 700 to 1,100 pounds (320 to 500 kilograms). Its rounded antlers can span more than 5 feet (1.5 meters). The antlers of a grown bull will have a total of about 12 to 14 points. Antlers grow during the spring and summer and are shed in late winter, so wildlife officials believe the elk got the tire stuck either in the winter or early spring. Cows, female elks, are smaller and do not have antlers. During September and October, bulls fight one another to gain control over harems, groups of cows. This activity distracts the elks from the presence of humans around them, making it a convenient time for officers to get the tire off.

 

Once the officers tranquilized the elk, they determined the animal was about 600-pounds (275 kilograms) in weight and 4 1/2 years old. The officers tried to cut the tire, but they were unable to do so when its steel reinforcement belts broke their saw. Luckily, there was still room around the elk’s neck to remove the tire after cutting off the antlers. The inside of the tire was packed with over 10 pounds (4.5 kilograms) of soil and pine needles. The elk’s neck was in good condition despite carrying around the heavy tire with debris for so long, and the elk’s antlers will grow back. After officials revived the elk, it quickly woke up, stood up, and walked away—tired no more. The officials kept the antlers and retired from their search.

Australia is famous for its unique culture, metropolitan cities, and unusual wildlife, among other things. Each week, this seasonal feature will spotlight one of Australia’s many wonders.

The inactive volcano and cultural site Budj Bim made history when, in 2019, it became the first World Heritage site listed exclusively for its value to Aboriginal culture. Such sites are places of unique cultural or natural importance as designated by the United Nations Educational, Scientific and Cultural Organization (UNESCO).

Budj Bim, once known as Mount Eccles, is located in southeastern Australia. The overlapping craters of Budj Bim hold lakes in which Aboriginal people maintained systems of aquaculture (the raising of water animals and plants) for thousands of years. Budj Bim means High Head in the language of the Gunditjmara people (also called the Dhauwurd Wurrung) of southwestern Victoria state. Budj Bim sits about 170 miles (270 kilometers) west of Melbourne. It is part of the 20,700-acre (8,370-hectare) Budj Bim National Park (formerly Mount Eccles National Park).

Gunditjmara tradition holds that Budj Bim is part of the body of an ancient creator being, who was revealed to Aboriginal people in an eruption around 30,000 years ago. The last known eruption of Budj Bim occurred about 8,000 years ago. Starting at least 6,600 years ago, the Gunditjmara people began creating a system of channels and dams to trap eels and other fish among the rock formations of Budj Bim. The result was an aquaculture system that provided plentiful food, and permanent Aboriginal settlements were established at nearby Lake Condah and Lake Gorrie. European settlers arrived in the area in the 1830’s.

Budj Bim—named Mount Eccles by European settlers—became a protected area in 1926 and a national park in 1960. Mount Eccles National Park was renamed Budj Bim National Park in 2017. The area is popular for camping, hiking, and picnicking.

Happy Earth Day!

Thursday, April 22nd, 2021

April 22 is Earth Day, an annual observance to increase public awareness of environmental issues. Each year on Earth Day, millions of people throughout the world gather to clean up litter, protest threats to the environment, and celebrate progress in reducing pollution.

Earth Day began in the United States. In 1969, the U.S. Senator Gaylord A. Nelson suggested that a day of environmental education be held on college campuses. The following year, the lawyer and environmentalist Denis Hayes, then a recent graduate of Stanford University, led hundreds of students in planning and organizing the observance of Earth Day on April 22, 1970. About 20 million people participated in this celebration.

The observance of Earth Day in 1970 helped alert people to the dangers of pollution and stimulated a new environmental movement. That same year, Congress created the Environmental Protection Agency to set and enforce pollution standards. Congress also passed the Clean Air Act of 1970, which limited the amount of air pollution that cars, utilities, and industries could release. Other new environmental laws soon followed.

One modern champion for the environment is the Swedish activist Greta Thunberg. She has worked to convince politicians to take action against climate change due to global warming. Global warming is an observed increase in Earth’s average surface temperature. As a teenager, Thunberg became known for her boldness in confronting adult politicians for their inaction on climate change. She has called upon leaders to reduce emissions of greenhouse gases, mainly carbon dioxide. Such gases trap heat in the atmosphere, warming the planet’s surface.

Thunberg was born in Stockholm, Sweden, on Jan. 3, 2003. She was diagnosed with autism spectrum disorder at a young age. As a child, she showed an interest in environmental issues. She convinced her family to reduce their carbon footprint by becoming vegan and giving up air travel. Carbon footprint is a measure of the greenhouse gas emissions associated with human activities.

In 2018, at the age of 15, Thunberg protested for action on climate change outside the Swedish parliament, inspiring other student protesters. Together, they organized school strikes to demand action on climate change. In August 2019, Thunberg sailed across the Atlantic Ocean from Plymouth, in the United Kingdom, to New York City, in the United States, on a “carbon neutral” voyage. Thunberg sailed aboard a yacht that got its electric power from solar panels and underwater turbines. While in the United States, she addressed the United Nations as part of its Climate Action Summit. During her speech, she announced that she and a group of other children were filing a lawsuit against five nations not on track to meet their emission-reduction targets under the Paris Agreement. The Paris Agreement is a global treaty designed to fight global warming.

Cloned Ferret Offers Hope for Endangered Species

Have you ever wanted to clone yourself? Maybe you thought, “While I play video games, my clone can do all my chores!” Well, if you are a black-footed ferret, it’s your lucky day. (But, we’re pretty sure black-footed ferrets don’t play video games.)

In December 2020, the weasel world welcomed a cloned black-footed ferret named Elizabeth Ann. She became the first of any endangered native North American species to be cloned. In a few years, Elizabeth Ann might have siblings. The successful cloning is promising, because it offers hope that cloned animals could help save species from extinction. Extinction occurs when every member of a species of a living thing has died.

In the past, black-footed ferrets lived throughout much of the Great Plains. They depended on hunting prairie dogs for food and lived in the prairie dogs’ underground burrows. Since the late 1800′s, however, ranchers have eliminated prairie dogs from much of the Great Plains because they consider the animals to be pests. The black-footed ferret has become rare as a result of the decline in prairie dogs. Disease and the loss of rangeland to agriculture have also reduced the ferret’s numbers. Scientists once thought black-footed ferrets were extinct.

In 1981, ranchers in Wyoming discovered a population of more than 125 black-footed ferrets. Over the next several years, many of these animals died of a disease called distemper. To keep them from dying out completely, the U.S. Fish and Wildlife Service and the Wyoming Game and Fish Department captured the remaining animals. Scientists have successfully bred the ferrets in captivity. In 1991, they began releasing captive-bred ferrets into western grasslands that were home to prairie dog populations. The ferrets began reproducing again in the wild.

The black-footed ferret is not the first animal to be cloned. Scientists used a technique called nuclear transfer to clone such amphibians as frogs and salamanders as early as the 1950′s. In 1996, a group led by the British scientist Ian Wilmut used the procedure to clone a sheep. The sheep was the first mammal cloned from a donor cell from an adult mammal. They named the clone “Dolly.” Since the cloning of Dolly, scientists from many countries have used a similar technique to produce clones of mice, cattle, cats, and other mammals.

Koala Counting Time

It’s summer in Australia, so you know what that means—time for a koala count! The Australian government has funded a project to count the population of the beloved teddy-bearlike mammals, as well as record where the marsupials (pouched mammals) live. The government commissioned this project because, in recent years, estimates of the koala population have varied greatly. In 2016, for instance, there were an estimated 300,000 koalas in Australia. Three years later, that number was down to 80,000, with some scientists saying the number was as low as 43,000.

In previous counts, people merely counted how many koalas they saw. But, koalas spend almost all their time in eucalyptus trees, making it difficult for people to spot them among the leaves. For the new count, humans will still venture into the forests to search for koalas. But, to ensure a koala-ty count, the government has also introduced some new methods. It will employ heat-seeking drones. A drone is an aircraft designed to operate without a pilot on board. The drones will detect the body heat that a koala gives off. The government will also use dropping-detection dogs—that is, dogs that identify koala droppings. The droppings serve as evidence that koalas live in the area. In addition to detecting droppings, these dogs can sniff out koalas themselves.

In recent years, the koala population has declined. People have cut down eucalyptus forests for housing developments, resorts, and farmland. In addition to spending most of their time in the forks of eucalyptus trees, koalas eat mainly the leaves and young shoots of eucalyptuses. They even get most of the water they need from eucalyptus leaves. Koalas are also vulnerable to natural disasters. Tens of thousands of koalas were killed when bushfires devastated large areas of Australia in late 2019 and early 2020. In fact, a study by the World Wildlife Fund (WWF) estimated that more than 60,000 koalas had been either killed, injured, or displaced by the fires. This staggering number led some scientists to say that the animal was “functionally extinct.”

There are efforts to increase the koala population in Australia. For instance, the WWF hopes to use drones to drop eucalyptus-tree seeds in forests. The WWF will also create a fund to sponsor koala sanctuaries (safe spaces).

Baby Panda Born!

This summer, a giant panda named Mei Xiang gave birth at Smithsonian’s National Zoo in Washington, D.C. At 22 years of age, she is the oldest giant panda in the United States to give birth.

The female giant panda gives birth every two or three years to one or two cubs. Panda cubs are extremely tiny, weighing only about 5 ounces (140 grams) at birth. In fact, panda cubs are about the size of a stick of butter! The mother, who normally spends about 12 hours a day eating, stays with the newborn cub for up to 10 days without feeding. Cubs normally nurse for about a year and may remain with the mother for more than two years.

The new cub has siblings. Mei Xiang has given birth to three surviving cubs. Tai Shan was born in 2005. Bao Bao was born in 2013. And, Bei Bei was born in 2015. All three pandas live in China.

Pandas are in danger of dying out completely. Widespread cutting of forests for wood and farmland in China has destroyed a large part of the habitat of giant pandas. China’s government has tried to protect these pandas by establishing reserves of bamboo-rich public land for them. They are protected by national and international laws.

Other efforts to ensure the survival of giant pandas have focused on breeding them in zoos, as happened with Mei Xiang. Giant pandas initially proved extremely difficult to breed in captivity. After years of failed attempts, scientists have made great progress in breeding the animals. Zoos now hold more than 300 giant pandas. This number is considered the minimum needed to preserve the animal. Scientists are researching methods for introducing pandas that were born in captivity into the wild.

Many people considered the birth a miracle, due to Mei Xiang’s advanced age. The birth also presented a much-needed cause for celebration during the ongoing pandemic (global outbreak) of the coronavirus disease COVID-19.

Wildfires ravage California

Wildfires have ravaged the U.S. state of California, killing at least 5 people and forcing thousands to evacuate (leave) their homes. Fueled by a heat wave and sparked by lightning strikes, the wildfires have set the state ablaze and covered the air in thick smoke.

Wildfire is the uncontrolled burning of large areas of vegetation. Wildfires may be ignited by human activities or by natural causes. Such natural causes include lightning, volcanic activity, or even intense sunlight. Wildfires occur on every continent except Antarctica. They are most common in the temperate forests and grasslands midway between the equator and the poles. They are less common in tropical and desert ecosystems.

These are far from California’s deadliest wildfires. Numerous major wildfires occurred in California in the early 2000′s. In 2003, wildfires in southern California destroyed thousands of homes and killed more than 20 people. In 2007, deadly wildfires forced the evacuation of about 500,000 people in San Diego County. In 2013, the so-called Rim Fire burned large areas of the Stanislaus National Forest near Yosemite National Park. Some of the largest wildfires in California history burned during the summer of 2018.

The unhealthy air quality caused by the wildfires is especially concerning, because of the pandemic (global outbreak) of the respiratory disease COVID-19. Smoke-polluted air can weaken lung function, reducing the body’s ability to fight infection.

The current round of fires was made worse by an intense heat wave baking the American Southwest. On August 16, temperatures in California’s Death Valley reached 130 °F (54.4 °C). If these measurements are confirmed, they would be the hottest surface air temperatures ever recorded on Earth.

Peru’s Potato Park

Monday, June 15th, 2020

In Peru, a unique conservation effort is taking place near the city of Cusco at the Parque de la Papa (Park of the Potato). Located outside the Andes Mountains town of Pisac (or Pisaq), the park celebrates the Peruvian potato, of which there are some 3,000 varieties. The park is also a living tribute to the cultural heritage of the region’s indigenous (native) communities.

The Parque de la Papa is administered and farmed by the local Amaru, Chawaytire, Pampallacta, Paru Paru, and Sacaca indigenous communities. Within its grand boundaries—the park covers over 22,000 acres (9,000 hectares)—are grown more than 1,300 varieties of potato native to that area of the Andean highlands. Many potato varieties in the park are found nowhere else in the world. The cultivation of such rare potatoes helps ensure their existence for future generations, as does the park’s sharing of precious seeds with the Svalbard Global Seed Vault, a long-term seed storage facility in Norway.

The Parque de la Papa demonstrates the ability of potatoes to survive in the region’s harsh but changing conditions. The park sits in the cold and thin air at an altitude of 12,000 feet (3,700 meters) above sea level. Climate change is bringing warmer temperatures, however, forcing farmers still higher to reach the optimum growing environment for some potato varieties.

Visitors to the park learn about traditional potato cultivation, harvesting, cooking, and storage. They are also treated to delicious local potato dishes. Hiking trails allow people to walk off their meals while also providing panoramic views of the Andean highlands. The Parque de la Papa features a variety of local crafts and products—from cosmetics and teas to medicines and textiles—made from potatoes and other plants native to the area.

The potato originated in the Andes Mountains of South America. Scientists believe cultivated potatoes came from a species that first grew around Lake Titicaca, in what are now Bolivia and Peru. People living there and in surrounding areas were growing potatoes long before Spanish explorers arrived in the early 1500′s. Potatoes were then introduced to Europe and other parts of the world. The nutritious potato became a vital food crop in many regions.

Officials in Washington state are working to stop an alien invader—the Asian giant hornet. Individuals of this species have been spotted there and to north, in the Canadian province of British Columbia, over the past couple years. Workers are setting traps in an attempt to prevent the species, nicknamed the “murder hornet,” from gaining a foothold and potentially devastating North American bee populations.

The Asian giant hornet is the largest hornet in the world. Workers grow up to 1 3/4 inches (4.5 centimeters) long. Queens may measure 2 1/5 inches (5.5 centimeters) long and have a wingspread of about 3 inches (7 centimeters). Asian giant hornets are aggressive and venomous (poisonous). They are found throughout Japan and Southeast Asia. The hornet’s head is light orange with dark antennae (feelers). The insect has a dark brown thorax (middle section). Its abdomen (hind section) has dark brown, black, and orange-yellow bands. Asian giant hornets build their nests underground, often in abandoned burrows made by other animals.

Asian giant hornets have piercing jaws and a 1/4-inch (0.5-centimeter) long stinger. They prey on such large insects as beetles and praying mantises. After the prey is stung and killed, adult hornet workers take the insect carcasses back to the nest. The hornets grind up the dead insects and feed them to their larvae (young). The larvae, in turn, produce a nutritious liquid for the workers to eat. Adults also sometimes feed on tree sap or rotting fruit.

Asian giant hornets are also known to swarm and attack beehives to eat the honey. A scout hornet will locate a beehive and then lead groups of other giant hornets in an attack. Asian giant hornets also attack people if their nest is disturbed. Multiple stings from the hornet can cause injury or death.
