The pineapple (Ananas comosus) is a tropical plant with an edible fruit; it is the most economically significant plant in the family Bromeliaceae.

The pineapple is indigenous to South America, where it has been cultivated for many centuries. The introduction of the pineapple to Europe in the 17th century made it a significant cultural icon of luxury. Since the 1820s, pineapple has been commercially grown in greenhouses and many tropical plantations.

Pineapples grow as a small shrub; the individual flowers of the unpollinated plant fuse to form a multiple fruit. The plant normally propagates from the offset produced at the top of the fruit or from a side shoot, and typically matures within a year

History

Etymology

The first reference in English to the pineapple fruit was the 1568 translation from the French of André Thevet's The New Found World, or Antarctike where he refers to a Hoyriri, a fruit cultivated and eaten by the Tupinambá people, living near modern Rio de Janeiro, and now believed to be a pineapple. Later in the same English translation, he describes the same fruit as a "Nana made in the manner of a Pine apple", where he used another Tupi word nanas, meaning 'excellent fruit'. This usage was adopted by many European languages and led to the plant's scientific binomial Ananas comosus, where comosus 'tufted', refers to the stem of the plant. Purchas, writing in English in 1613, referred to the fruit as Ananas, but the Oxford English Dictionary's first record of the word pineapple itself by an English writer is by Mandeville in 1714

Precolonial cultivation

The wild plant originates from the Paraná–Paraguay River drainages between southern Brazil and Paraguay. Little is known about its domestication, but it spread as a crop throughout South America. Archaeological evidence of use is found as far back as 1200 – 800 BC (3200–2800 BP) in Peru and 200BC – AD700 (2200–1300 BP) in Mexico, where it was cultivated by the Mayas and the Aztecs. By the late 1400s, cropped pineapple was widely distributed and a staple food of Native Americans. The first European to encounter the pineapple was Columbus, in Guadeloupe on 4 November 1493. The Portuguese took the fruit from Brazil and introduced it into India by 1550. The 'Red Spanish [es]' cultivar was also introduced by the Spanish from Latin America to the Philippines, and it was grown for textile use from at least the 17th century.

Columbus brought the plant back to Spain and called it piña de Indes, meaning "pine of the Indians". The pineapple was documented in Peter Martyr's Decades of the New World (1516) and Antonio Pigafetta's Relazione del primo viaggio intorno al mondo (1524-1525), and the first known illustration was in Oviedo's Historia General de Las Indias (1535)

Old World introduction

The pineapple fascinated Europeans as a fruit of colonialism. But it was not successfully cultivated in Europe until Pieter de la Court developed greenhouse horticulture near Leiden from about 1658. Pineapple plants were distributed from the Netherlands to English gardeners in 1719 and French ones in 1730. In England, the first pineapple was grown at Dorney Court, Dorney in Buckinghamshire, and a huge "pineapple stove" to heat the plants was built at the Chelsea Physic Garden in 1723. In France, King Louis XV was presented with a pineapple that had been grown at Versailles in 1733. In Russia, Peter the Great imported de le Court's method into St. Petersburg in the 1720s; in 1730, 20 pineapple saplings were transported from there to a greenhouse at Empress Anna's new Moscow palace.

Because of the expense of direct import and the enormous cost in equipment and labour required to grow them in a temperate climate, in greenhouses called "pineries", pineapple became a symbol of wealth. They were initially used mainly for display at dinner parties, rather than being eaten, and were used again and again until they began to rot. In the second half of the 18th century, the production of the fruit on British estates became the subject of great rivalry between wealthy aristocrats. John Murray, 4th Earl of Dunmore, built a hothouse on his estate surmounted by a huge stone cupola 14 metres tall in the shape of the fruit; it is known as the Dunmore Pineapple. In architecture, pineapple figures became decorative elements symbolizing hospitality.

Since 19th century: mass commercialization

Many different varieties, mostly from the Antilles, were tried for European glasshouse cultivation. The most significant was "Smooth Cayenne", imported to France in 1820, subsequently re-exported to the United Kingdom in 1835, and then from the UK via Hawaii `to Australia and Africa. "Smooth Cayenne" is now the dominant cultivar in world production. Jams and sweets based on pineapple were imported to Europe from the West Indies, Brazil, and Mexico from an early date. By the early 19th century, fresh pineapples were transported direct from the West Indies in large enough quantities to reduce European prices. Later pineapple production was dominated by the Azores for Europe, and Florida and the Caribbean for North America, because of the short trade routes.

The Spanish had introduced the pineapple into Hawaii in the 18th century where it is known as the hala kahiki ("foreign hala"), but the first commercial plantation was established in 1886. The most famous investor was James Dole, who moved to Hawaii in 1899 and started a 24-hectare (60-acre) pineapple plantation in 1900 which would grow into the Dole Food Company. Dole and Del Monte began growing pineapples on the island of Oahu in 1901 and 1917, respectively, and the Maui Pineapple Company began cultivation on Maui in 1909. James Dole began the commercial processing of pineapple, and Dole employee Henry Ginaca invented an automatic peeling and coring machine in 1911.

Hawaiian production started to decline from the 1970s because of competition and the shift to refrigerated sea transport. Dole ceased its cannery operations in Honolulu in 1991, and in 2008, Del Monte terminated its pineapple-growing operations in Hawaii. In 2009, the Maui Pineapple Company reduced its operations to supply pineapples only locally on Maui, and by 2013, only the Dole Plantation on Oahu grew pineapples in a volume of about 0.1 percent of the world's production. Despite this decline, the pineapple is sometimes used as a symbol of Hawaii. Further, foods with pineapple in them are sometimes known as "Hawaiian" for this reason alone.

In the Philippines, "Smooth Cayenne" was introduced in the early 1900s by the US Bureau of Agriculture during the American colonial period. Dole and Del Monte established plantations in the island of Mindanao in the 1920s; in the provinces of Cotabato and Bukidnon, respectively. Large scale canning had started in Southeast Asia, including in the Philippines, from 1920. This trade was severely damaged by World War II, and Hawaii dominated the international trade until the 1960s.

The Philippines remain one of the top exporters of pineapples in the world.

An orange is a fruit of various citrus species in the family Rutaceae (see list of plants known as orange); it primarily refers to Citrus × sinensis,[1] which is also called sweet orange, to distinguish it from the related Citrus × aurantium, referred to as bitter orange. The sweet orange reproduces asexually (apomixis through nucellar embryony); varieties of the sweet orange arise through mutations.

The orange is a hybrid between pomelo (Citrus maxima) and mandarin (Citrus reticulata). The chloroplast genome, and therefore the maternal line, is that of pomelo. The sweet orange has had its full genome sequenced.

The orange originated in a region encompassing Southern China, Northeast India, and Myanmar, and the earliest mention of the sweet orange was in Chinese literature in 314 BC. As of 1987, orange trees were found to be the most cultivated fruit tree in the world. Orange trees are widely grown in tropical and subtropical climates for their sweet fruit. The fruit of the orange tree can be eaten fresh, or processed for its juice or fragrant peel. As of 2012, sweet oranges accounted for approximately 70% of citrus production.

In 2019, 79 million tonnes of oranges were grown worldwide, with Brazil producing 22% of the total, followed by China and India.

History

The sweet orange is not a wild fruit, having arisen in domestication from a cross between a non-pure mandarin orange and a hybrid pomelo that had a substantial mandarin component. Since its chloroplast DNA is that of pomelo, it was likely the hybrid pomelo, perhaps a BC1 pomelo backcross, that was the maternal parent of the first orange. Based on genomic analysis, the relative proportions of the ancestral species in the sweet orange are approximately 42% pomelo and 58% mandarin. All varieties of the sweet orange descend from this prototype cross, differing only by mutations selected for during agricultural propagation. Sweet oranges have a distinct origin from the bitter orange, which arose independently, perhaps in the wild, from a cross between pure mandarin and pomelo parents. The earliest mention of the sweet orange in Chinese literature dates from 314 BC.

In Europe, the Moors introduced the orange to the Iberian Peninsula, which was known as Al-Andalus, with large-scale cultivation starting in the 10th century, as evidenced by complex irrigation techniques specifically adapted to support orange orchards. Citrus fruits—among them the bitter orange—were introduced to Sicily in the 9th century during the period of the Emirate of Sicily, but the sweet orange was unknown until the late 15th century or the beginnings of the 16th century, when Italian and Portuguese merchants brought orange trees into the Mediterranean area. Shortly afterward, the sweet orange quickly was adopted as an edible fruit. It was considered a luxury food grown by wealthy people in private conservatories, called orangeries. By 1646, the sweet orange was well known throughout Europe. Louis XIV of France had a great love of orange trees and built the grandest of all royal Orangeries at the Palace of Versailles. At Versailles, potted orange trees in solid silver tubs were placed throughout the rooms of the palace, while the Orangerie allowed year-round cultivation of the fruit to supply the court. When Louis condemned his finance minister, Nicolas Fouquet, in 1664, part of the treasures that he confiscated were over 1,000 orange trees from Fouquet's estate at Vaux-le-Vicomte.

Spanish travelers introduced the sweet orange to the American continent. On his second voyage in 1493, Christopher Columbus may have planted the fruit on Hispaniola. Subsequent expeditions in the mid-1500s brought sweet oranges to South America and Mexico, and to Florida in 1565, when Pedro Menéndez de Avilés founded St Augustine. Spanish missionaries brought orange trees to Arizona between 1707 and 1710, while the Franciscans did the same in San Diego, California, in 1769. An orchard was planted at the San Gabriel Mission around 1804, and a commercial orchard was established in 1841 near present-day Los Angeles. In Louisiana, oranges were probably introduced by French explorers.

Archibald Menzies, the botanist and naturalist on the Vancouver Expedition, collected orange seeds in South Africa, raised the seedlings onboard, and gave them to several Hawaiian chiefs in 1792. Eventually, the sweet orange was grown in wide areas of the Hawaiian Islands, but its cultivation stopped after the arrival of the Mediterranean fruit fly in the early 1900s.

As oranges are rich in vitamin C and do not spoil easily, during the Age of Discovery, Portuguese, Spanish, and Dutch sailors planted citrus trees along trade routes to prevent scurvy.

Florida farmers obtained seeds from New Orleans around 1872, after which orange groves were established by grafting the sweet orange on to sour orange rootstocks.

The Northern Pygmy-Owl may be tiny, but it’s a ferocious hunter with a taste for songbirds. These owls are mostly dark brown and white, with long tails, smoothly rounded heads, and piercing yellow eyes. They hunt during the day by sitting quietly and surprising their prey. As a defensive measure, songbirds often gather to mob sitting owls until they fly away. Mobbing songbirds can help you find these unobtrusive owls, as can listening for their call, a high-pitched series of toots. (toots? Lol)

Northern Pygmy-Owls are widespread in the mountains of western North America, and they’re active during the day, which gives you a good chance of finding them. But they’re also small and unobtrusive as they sit and wait for prey to approach them, so you’ll need to be observant. The two best ways to find them involve your ears: you may hear them giving high, evenly spaced tooting calls. Or you may hear a commotion of chickadees and other small birds scolding and calling as they mob an owl they’ve discovered. Try to find the agitated birds and you may find the owl that they’re trying to drive away.

When they find extra food, Northern Pygmy-Owls often cache their prey in tree cavities, or by hanging the prey on thorns, as shrikes are famous for doing. (Jesus Christ how can something so cute be that monstrous lol)

Most owls have asymmetrically placed ears as well as flattened facial discs around the eyes. Both of these features are adaptations that give them better hearing. Interestingly, Northern Pygmy-Owls lack these features, and this may be an outcome of their diurnal habits and greater reliance on vision.

Northern Pygmy-Owls raise a pair of tufts on the sides of their head when threatened by a predator, such as a hawk or a cat. They also have a pair of spots on the back of the neck that look a little like eyes. Scientists think these markings may help fool attackers or mobbers into thinking the owl is watching them.

Northern Pygmy-Owls, although not much larger than House Sparrows, sometimes take prey up to three times their own size, such as Northern Bobwhite, Northern Flicker, and even chickens!

What a little shithead.

Grouped by habitat. These are full sun prairie ones- sunflower, firewheel, milkweed, bee balm. I mix them equal parts into clay/fertiliser balls to seed unattended beds. More flowers throughout the season for more pollinator support, all public spaces with soil becoming art nouveau exhibits. screm-cool

Bought a tent that fits in my kayak. I want to do a one-way camping trip where I go down a river. To get there I will almost certainly have to drive. So I need either

  • A way to move my car down the river so that I can meet it via kayak
  • A way to return myself and kayak to the car
  • A huge 2+day oxbow where the end of the river is only a short hike from the start

How do I find a portage company? Anyone else who has done this? Rental companies often handle this for day trips but I don't know what Google keywords to use for a portage company for your own boat.

I'm in Chicago. I've brought the kayak on the CTA for a day trip down the Chicago river. Inflatable kayak is very bulky and must be carried with one hand, it was kind of a struggle after a quarter mile and it can't fit in a backpack. It would be cool to take one Metra spoke out to a river where I could paddle to a different Metra line to return, but with tent/food/camping supplies it's probably going to be too much to hike with or comfortably carry on the train.

Tristan Jameson, the commercial beekeeper who was hauling the bees on a trailer attached to a pickup truck, told the Canadian news outlet Global News that he had swerved to avoid something he had seen moving across the road and then “nearly swerved into the ditch, tried to correct, and dumped all the hives.”

[...]

Mr. Barber said that so many bees had escaped from their boxes that “the sky was dark with bees. It was something else.” Other beekeepers were calling him to see if they could help, but he couldn’t hear his phone ringing above the din, he said. “When you’re in that cloud of bees,” he said, “it’s actually quite loud — a million little helicopters flying around you.”

[...]

Reflecting on the experience as she finally ate breakfast late Wednesday morning, Ms. Faloney said it was beautiful to have seen so many beekeepers working together to save the bees. “It was just nice to see everybody get there quickly,” she said. “Some drove 10 minutes and some drove an hour. We’re very, very lucky to be in this community.” Said Mr. Barber: “We all swarmed to help — bee pun intended.”

The sea-ice underneath the chicks melted and broke apart before they could develop the waterproof feathers needed to swim in the ocean.

The birds most likely drowned or froze to death.

The event, in late 2022, occurred in the west of the continent in an area fronting on to the Bellingshausen Sea.

It was recorded by satellites.

Dr Peter Fretwell, from the British Antarctic Survey (BAS), said the wipeout was a harbinger of things to come.

More than 90% of emperor penguin colonies are predicted to be all but extinct by the end of the century, as the continent's seasonal sea-ice withers in an ever-warming world.

"Emperors depend on sea-ice for their breeding cycle; it's the stable platform they use to bring up their young. But if that ice is not as extensive as it should be or breaks up faster, these birds are in trouble," he told BBC News.

"There is hope: we can cut our carbon emissions that are causing the warming. But if we don't we will drive these iconic, beautiful birds to the verge of extinction."

Dr Fretwell and colleagues report the die-off in the journal Communications Earth & Environment: https://www.nature.com/articles/s43247-023-00927-x

The scientists tracked five colonies in the Bellingshausen Sea sector - at Rothschild Island, Verdi Inlet, Smyley Island, Bryan Peninsula and Pfrogner Point.

Using the EU's Sentinel-2 satellites, they were able to observe the penguins' activity from the excrement, or guano, they left on the white sea-ice.

This brown staining is visible even from space.

Adult birds jump out on to the sea-ice around March as the Southern Hemisphere winter approaches. They court, copulate, lay eggs, brood those eggs, and then feed their nestlings through the following months until it's time for the young to make their own way in the world.

This normally occurs around December/January time, when the new birds head out into the ocean.

But the research team watched as sea-ice under emperor rookeries fragmented in November, before thousands of chicks had had time to fledge the slick feathers needed for swimming.

Four of the colonies suffered total breeding failure as a result. Only the most northerly site, at Rothschild Island, had some success.

Antarctic summer sea-ice has been on a sharp downturn since 2016, with the total area of frozen water around the continent diminishing to new record lows.

The two absolute lowest years have occurred in the past two summer seasons, in 2021/22 and in 2022/23, when the Bellingshausen was almost completely devoid of ice cover.

What is more, the slowness of floes to form in recent months means the colonies will probably not be producing chicks for at least another year.

Winter maximum sea-ice extent, normally reached in September, will track far below where it would normally be. A diving emperorImage source, Getty Images Image caption, Scientists believe the emperor will see its range greatly restricted as the century progresses

Dr Fretwell and colleagues said the emperors were feeling the impacts of this shift in conditions. Between 2018 and 2022, roughly a third of the more than 60 known emperor penguin colonies were affected in some way by diminished sea-ice extent - whether that's ice forming later in the season or breaking up earlier.

At the other end of the planet, in the Arctic, the sea-ice has been in a decades-long, steady decline. The Antarctic in contrast seemed more robust. Up until 2016, it was becoming slightly more extensive year on year.

BAS colleague Dr Caroline Holmes is an expert on Antarctic sea-ice. She links the causes for the current decline to anomalously warm ocean water around the continent and a particular pattern of winds, which in the case of the Bellingshausen, has pushed ice back towards the coast, making it difficult to spread. Sea-ice extent Image caption, Sea-ice extent is currently far, far below where it should be

These were remarkable times, she said.

"What we're seeing right now is so far outside what we've observed previously. We expected change but I don't think we expected so much change so rapidly," she told BBC News.

"Studies in the Arctic have suggested that if we could reverse climate warming somehow, the sea-ice in the polar north would recover. Whether that might also apply in the Antarctic, we don't know. But there's every reason to think that if it got cold enough, the sea-ice would reform."

Currently, emperors are classified as "Near Threatened" by the International Union for Conservation of Nature (IUCN), the organisation that keeps the lists of Earth's most endangered animals.

A proposal has been made to lift emperors into the more urgent "Vulnerable" category because of the danger posed by climate warming to their way of life.

Nineteen Bob Brown Foundation forest defenders are in Tasmania's Florentine Valley this morning, protecting the tallest flowering trees on Earth which continue to be destroyed by logging.

This valley full of giant eucalypts has been the site of ongoing protests recently as shocking footage emerged of gigantic trees being hauled out of this ancient forest.

One protester is in a treesit high above the forest floor with another locked onto logging machinery.

"It is criminal behaviour to harvest this forest. If anyone tells you that native forest logging sequesters carbon, please think about that for a moment. Clear felling massive trees and burning the soil, it will take centuries for the forest to re-capture that carbon," said treesitter Aden Wachtel, a 33-year-old gardener.

"Our biodiversity is precious, and all our lives are on the line. That's why I'm climbing up into a tree sit to defend this forest," Mr Wachtel said.

This herd is really neat. Bison have a disease called brucellosis which makes pregnancy nonviable and spreads to other species: https://www.nps.gov/yell/learn/nature/brucellosis.htm

Colorado State University pioneered an IVF technique to rid embryos of the disease and diversify their gene pool. They ship these healthy bison to various Native American tribal herds across the US and Canada for a progressive reintroduction of purebred bison to the Great Plains which evolved to have them as seasonal grazers.
