WonderWildlife migration fact

Pronghorn from Grand Teton National Park travel up to about 240 km (150 miles) between their summer range and their winter range in Wyoming's Upper Green River Basin. Roads, fences and new building now cut across this ancient route.

The story behind the card

Pronghorn look like antelopes but are the last surviving members of a family found only in North America. They can reach about 88 km/h, a speed beaten on land only by the cheetah, yet they rarely jump: faced with a fence, they look for a gap to crawl under, so tight wire fencing can block a route completely. At Trappers Point, a narrow bottleneck on the route, archaeologists found remains of pronghorn hunts about 6,000 years old. In 2008 the US Forest Service designated the Path of the Pronghorn, the first federally protected wildlife migration corridor in the United States. In 2012, overpasses and underpasses built on US Highway 191 near Pinedale gave the herds a safe way across the road.

Grand Teton Ulusal Parkı'nın Amerika antilopları (pronghorn), yaz otlaklarıyla Wyoming'deki Yukarı Green River Havzası'nda bulunan kışlakları arasında 240 kilometreye (150 mil) kadar yol alır. Çok eski olan bu göç yolunu bugün karayolları, çitler ve yeni yapılar kesiyor.

Amerika antilobu antilopa benzer ama gerçek bir antilop değildir; yalnızca Kuzey Amerika'da yaşamış bir ailenin bugün hayatta kalan tek türüdür. Saatte 88 kilometreye kadar koşabilir; karada ondan hızlı olan tek hayvan çitadır. Ama pek zıplamaz: önüne çit çıkınca altından geçebileceği bir boşluk arar, bu yüzden sık örülmüş tel çitler yolu tümüyle kapatabilir. Göç yolunun daraldığı Trappers Point'te arkeologlar, yaklaşık 6.000 yıl önce yapılmış antilop avlarının kalıntılarını buldu. ABD Orman Servisi 2008'de bu güzergâhı “Path of the Pronghorn” (Pronghorn Yolu) adıyla ülkenin federal düzeyde korunan ilk yaban hayatı göç koridoru ilan etti. 2012'de Pinedale yakınlarında 191 numaralı karayolunun üstüne ve altına yapılan geçitler, sürülere yolu güvenle aşma imkânı verdi.

Every year more than a million wildebeest, joined by hundreds of thousands of zebras and gazelles, walk a great loop through Tanzania's Serengeti and Kenya's Maasai Mara, following the rains to fresh grass.

The herds have no fixed route; their path shifts each year with the rain. Early in the year hundreds of thousands of calves are born within a few weeks in the southern Serengeti. As the plains dry out the herds move north and west, reach Kenya's Mara in the middle of the year and return south when the short rains begin. The most dangerous moment is crossing the Mara River. A 2017 study found that on average about 6,250 wildebeest drown there each year, and their carcasses, some 1,100 tonnes, feed fish, crocodiles and vultures and fertilise the river for years. Grazing herds also keep the grasslands healthy.

Eastern monarch butterflies fly up to 4,800 kilometres from Canada and the United States to the mountains of central Mexico each autumn, yet no single butterfly makes the whole round trip: the yearly cycle takes about four generations.

The butterflies that fly south in late summer are a special generation: they live about eight months, while the summer generations before them live less than two. They spend the winter packed by the million on oyamel fir trees in the mountains of Michoacán and the State of Mexico, then start north in spring, lay eggs on milkweed in the southern United States and die. Milkweed is the only food their caterpillars eat. Their children and grandchildren carry on northwards. Where the monarchs wintered was a mystery until January 1975, when Kenneth Brugger and Catalina Aguado (later Trail), volunteers helping the Canadian zoologist Fred Urquhart, found the first colony.

The saiga, an antelope of the Central Asian steppes, has an enlarged, flexible nose that filters out dust in summer and warms and moistens freezing air in winter before it reaches the lungs.

Saigas live on the dry grasslands of Kazakhstan, Russia, Uzbekistan and Mongolia, and herds migrate hundreds of kilometres between summer and winter pastures. Their numbers collapsed after the Soviet Union broke up: poaching of males for their horns, used in traditional Chinese medicine, cut the population by about 95 per cent. In May 2015, during unusually warm, humid weather, a bacterium the animals normally carry harmlessly, Pasteurella multocida, caused a blood infection that killed about 200,000 saigas in Kazakhstan within a few weeks, more than half of all saigas then alive. Protection from poaching has since let the Kazakh herds recover so strongly that in 2023 the International Union for Conservation of Nature moved the species from Critically Endangered to Near Threatened.

Mangroves, salt marshes and seagrass meadows draw carbon dioxide from the air and lock it away in waterlogged coastal mud, often for centuries. Scientists call this stored carbon 'blue carbon'.

The term was popularised by a 2009 United Nations report. Coastal mud holds so little oxygen that dead roots and leaves rot very slowly, so carbon keeps building up in the soil instead of returning to the air. These habitats cover only a small fraction of the seabed, yet they are thought to account for about half of all the carbon buried in ocean sediments. Mangroves also break waves, trap sediment and shelter young fish and crabs among their roots. When the wetlands are drained or cleared for shrimp farms or building, the stored carbon can escape back into the atmosphere.

Whales feed at depth and release nutrient-rich faeces near the surface, fertilising the phytoplankton, tiny drifting algae, at the base of the ocean food chain. Scientists call this the whale pump.

The term comes from a 2010 study by the marine scientists Joe Roman and James McCarthy, who looked at whales and seals in the Gulf of Maine, off the north-eastern United States. Many whales dive to feed and then rest and breathe at the surface, where they release loose, floating plumes of faeces rich in nitrogen. The researchers estimated that marine mammals return about 23,000 tonnes of nitrogen a year to the sunlit surface layer of the Gulf, more than all the rivers flowing into it combined, and that before industrial whaling the flow was probably much larger. Other studies found a similar effect with iron in the Southern Ocean. Because phytoplankton also absorb carbon dioxide, recovering whale numbers may help both ocean productivity and carbon uptake.
