Baby lobsters nurtured in Northumberland to boost life chances | ITV News Tyne Tees
Thursday 9 November 2017
Baby lobsters are being nurtured in Northumberland to improve their chances of making it to adulthood. Female lobsters are brought to the Northumberland Seafood Centre's Hatchery, where their eggs are carefully packaged and preserved in sea-like conditions. After they've been given time to develop the eggs are taken on board a conservation boat. The boat then takes them out to sea and lays them on the sea bed.
In the wild, about 1 in 20,000 of the eggs make it to be an adult lobster. When we take them through the process in the hatchery, about half of those will make it to be an adult lobster.
"So if I was a lobster I'd be much happier with my chances."
Andrew Gooding, Northumberland Seafood Centre Manager
Their mothers are also set free at sea. Before they're unloaded, conservation officers put a notch in their tail which means fishermen can't land them until the notch has grown out, helping raise lobster numbers and awareness. The baby lobsters disappear into the sea bed for three years until they resurface as fully grown adults. Some may then even return to the lobster hatchery to help breed the next generation.

The dingo is an ancient (basal) lineage of dog found in Australia. Its taxonomic classification is debated as indicated by the variety of scientific names presently applied in different publications. It is variously considered a form of domestic dog not warranting recognition as a subspecies, a subspecies of dog or wolf, or a full species in its own right.
The dingo is a medium-sized canine that possesses a lean, hardy body adapted for speed, agility, and stamina. The dingo's three main coat colourations are light ginger or tan, black and tan, or creamy white. The skull is wedge-shaped and appears large in proportion to the body. The dingo is closely related to the New Guinea singing dog: their lineage split early from the lineage that led to today's domestic dogs, and can be traced back through Maritime Southeast Asia to Asia. The oldest remains of dingoes in Australia are around 3,500 years old.
A dingo pack usually consists of a mated pair, their offspring from the current year, and sometimes offspring from the previous year.
Etymology
The name "dingo" comes from the Dharug language used by the Indigenous Australians of the Sydney area. The first British colonists to arrive in Australia in 1788 established a settlement at Port Jackson and noted "dingoes" living with indigenous Australians. The dingo has different names in different indigenous Australian languages, such as boolomo, dwer-da, joogoong, kal, kurpany, maliki, mirigung, noggum, papa-inura, and wantibirri.
Domestic status
The dingo is regarded as a feral dog because it descended from domesticated ancestors. The dingo's relationship with indigenous Australians is one of commensalism, in which two organisms live in close association, but do not depend on each other for survival. They both hunt and sleep together. The dingo is, therefore, comfortable enough around humans to associate with them, but is still capable of living independently. Any free-ranging, unowned dog can be socialised to become an owned dog, as some dingoes do when they join human families
History
The earliest known dingo remains, found in Western Australia, date to 3,450 years ago. Based on a comparison of modern dingoes with these early remains, dingo morphology has not changed over thousands of years. This suggests that no artificial selection has been applied over this period and that the dingo represents an early form of dog.[40] They have lived, bred, and undergone natural selection in the wild, isolated from other dogs until the arrival of European settlers, resulting in a unique breed.
Hybrids, distribution and habitat
The wolf-like canids are a group of large carnivores that are genetically closely related because their chromosomes number 78, therefore they can potentially interbreed to produce fertile hybrids. In the Australian wild there exist dingoes, feral dogs, and the crossings of these two, which produce dingo–dog hybrids.
Dingoes occurred throughout mainland Australia before European settlement. They are not found in the fossil record of Tasmania, so they apparently arrived in Australia after Tasmania had separated from the mainland due to rising sea levels. The introduction of agriculture reduced dingo distribution, and by the early 1900s, large barrier fences, including the Dingo Fence, excluded them from the sheep-grazing areas. Land clearance, poisoning, and trapping caused the extinction of the dingo and hybrids from most of their former range in southern Queensland, New South Wales, Victoria, and South Australia. Today, they are absent from most of New South Wales, Victoria, the southeastern third of South Australia, and the southwestern tip of Western Australia. They are sparse in the eastern half of Western Australia and the adjoining areas of the Northern Territory and South Australia. They are regarded as common across the remainder of the continent.
The dingo's present distribution covers a variety of habitats, including the temperate regions of eastern Australia, the alpine moorlands of the eastern highlands, the arid hot deserts of Central Australia, and the tropical forests and wetlands of Northern Australia. The occupation of, and adaption to, these habitats may have been assisted by their relationship with indigenous Australians.
Prey
The study found that these canines prey on 177 species represented by 72.3% mammals (71 species), 18.8% birds (53 species), 3.3% vegetation (seeds), 1.8% reptiles (23 species), and 3.8% insects, fish, crabs, and frogs (28 species). The relative proportions of prey are much the same across Australia, apart from more birds being eaten in the north and south-east coastal regions, and more lizards in Central Australia.
Communication
Compared to most domestic dogs, the bark of a dingo is short and monosyllabic, and is rarely used. Barking was observed to make up only 5% of vocalisations. Dog barking has always been distinct from wolf barking. Australian dingoes bark mainly in swooshing noises or in a mixture of atonal and tonal sounds.
Dingoes have three basic forms of howling (moans, bark-howls, and snuffs) with at least 10 variations. Usually, three kinds of howls are distinguished: long and persistent, rising and ebbing, and short and abrupt.
Additionally, howling seems to have a group function, and is sometimes an expression of joy (for example, greeting-howls).
Behaviour
Dingoes tend to be nocturnal in warmer regions, but less so in cooler areas. Their main period of activity is around dusk and dawn. The periods of activity are short (often less than 1 hour) with short times of resting. Dingoes have two kinds of movement: a searching movement (apparently associated with hunting) and an exploratory movement (probably for contact and communication with other dogs). According to studies in Queensland, the wild dogs (dingo hybrids) there move freely at night through urban areas and cross streets and seem to get along quite well.

I don't know what to say, so I will simply unload some of my heart and just be honest. This is an attempted GoFundMe for a long time pen pal friend I have in Gaza. She is a very beautiful person that I have corresponded with for years. I have been the only one whose donated despite sharing with the few friends I have and some family , a cousin of mine will donate soon. It has been up for a month with no donations in part because GoFundMe kept shafting it but I have now fixed it. I could barely muster the will to write about something so unbearable in such a dry and clinical way. I have no illusions that this will achieve the 10,000 goal but one must look towards the sun. I will be messaging popular Twitter users to try and share this later.
Sorry if this isn't the most moving post for something so important . I did landscaping work today an had a couple of beers after just to gain the courage to post this despite mostly being sober lately so I can read books more.
Please watch Balaha's two beautiful short films linked in the GoFundMe that I uploaded to YouTube, they were shot with an old iPhone. And also please let me know if my GoFundMe description is too personal and off putting. https://gofund.me/7365562f

The red fox (Vulpes vulpes) is the largest of the true foxes and one of the most widely distributed members of the order Carnivora, being present across the entire Northern Hemisphere including most of North America, Europe and Asia, plus parts of North Africa. It is listed as least concern on the IUCN Red List. Its range has increased alongside human expansion, having been introduced to Australia, where it is considered harmful to native mammals and bird populations. Due to its presence in Australia, it is included on the list of the "world's 100 worst invasive species".
The red fox originated from smaller-sized ancestors from Eurasia during the Middle Villafranchian period, and colonised North America shortly after the Wisconsin glaciation. Among the true foxes, the red fox represents a more progressive form in the direction of carnivory. Apart from its large size, the red fox is distinguished from other fox species by its ability to adapt quickly to new environments. Despite its name, the species often produces individuals with other colourings, including leucistic and melanistic individuals. Forty-five subspecies are currently recognised,[7] which are divided into two categories: the large northern foxes and the small, basal southern grey desert foxes of Asia and North Africa.
Red foxes are usually found in pairs or small groups consisting of families, such as a mated pair and their young, or a male with several females having kinship ties. The young of the mated pair remain with their parents to assist in caring for new kits.[8] The species primarily feeds on small rodents, though it may also target rabbits, squirrels, game birds, reptiles, invertebrates and young ungulates. Fruit and vegetable matter is also eaten sometimes. Although the red fox tends to kill smaller predators, including other fox species, it is vulnerable to attack from larger predators, such as wolves, coyotes, golden jackals, large predatory birds such as golden eagles and Eurasian eagle owls, and medium- and large-sized felids.
The species has a long history of association with humans, having been extensively hunted as a pest and furbearer for many centuries, as well as being represented in human folklore and mythology. Because of its widespread distribution and large population, the red fox is one of the most important furbearing animals harvested for the fur trade. Too small to pose a threat to humans, it has extensively benefited from the presence of human habitation, and has successfully colonised many suburban and urban areas. Domestication of the red fox is also underway in Russia, and has resulted in the domesticated silver fox.

The coyote (Canis latrans) is a species of canine native to North America. It is smaller than its close relative, the gray wolf, and slightly smaller than the closely related eastern wolf and red wolf. It fills much of the same ecological niche as the golden jackal does in Eurasia. The coyote is larger and was once referred to as the American jackal by a behavioral ecologist. Other historical names for the species include the prairie wolf and the brush wolf.
The coyote is listed as least concern by the International Union for Conservation of Nature, due to its wide distribution and abundance throughout North America. The species is versatile, able to adapt to and expand into environments modified by humans; urban coyotes are common in many cities. The coyote was sighted in eastern Panama (across the Panama Canal from their home range) for the first time in 2013.
The coyote has 19 recognized subspecies. The average male weighs 8 to 20 kg (18 to 44 lb) and the average female 7 to 18 kg (15 to 40 lb). Their fur color is predominantly light gray and red or fulvous interspersed with black and white, though it varies somewhat with geography. It is highly flexible in social organization, living either in a family unit or in loosely knit packs of unrelated individuals. Primarily carnivorous, its diet consists mainly of deer, rabbits, hares, rodents, birds, reptiles, amphibians, fish, and invertebrates, though it may also eat fruits and vegetables on occasion. Its characteristic vocalization is a howl made by solitary individuals. Humans are the coyote's greatest threat, followed by cougars and gray wolves. Despite predation by gray wolves, coyotes sometimes mate with them, and with eastern, or red wolves, producing "coywolf" hybrids. In the northeastern regions of North America, the eastern coyote (a larger subspecies, though still smaller than wolves) is the result of various historical and recent matings with various types of wolves. Genetic studies show that most North American wolves contain some level of coyote DNA.
The coyote is a prominent character in Native American folklore, mainly in Aridoamerica, usually depicted as a trickster that alternately assumes the form of an actual coyote or a man. As with other trickster figures, the coyote uses deception and humor to rebel against social conventions. The animal was especially respected in Mesoamerican cosmology as a symbol of military might. After the European colonization of the Americas, it was seen in Anglo-American culture as a cowardly and untrustworthy animal. Unlike wolves, which have seen their public image improve, attitudes towards the coyote remain largely negative.
Behavior
Like the Eurasian golden jackal, the coyote is gregarious, but not as dependent on conspecifics as more social canid species like wolves are. This is likely because the coyote is not a specialized hunter of large prey as the latter species is. The basic social unit of a coyote pack is a family containing a reproductive female. However, unrelated coyotes may join forces for companionship, or to bring down prey too large to attack singly. Such "nonfamily" packs are only temporary, and may consist of bachelor males, nonreproductive females and subadult young. Families are formed in midwinter, when females enter estrus. Pair bonding can occur 2–3 months before actual copulation takes place
When hunting large prey, the coyote often works in pairs or small groups. Success in killing large ungulates depends on factors such as snow depth and crust density. Younger animals usually avoid participating in such hunts, with the breeding pair typically doing most of the work. The coyote pursues large prey, typically hamstringing the animal, and subsequently then harassing it until the prey falls. Like other canids, the coyote caches excess food. Coyotes catch mouse-sized rodents by pouncing, whereas ground squirrels are chased. Although coyotes can live in large groups, small prey is typically caught singly
Habitat
Prior to the near extermination of wolves and cougars, the coyote was most numerous in grasslands inhabited by bison, pronghorn, elk, and other deer, doing particularly well in short-grass areas with prairie dogs, though it was just as much at home in semiarid areas with sagebrush and jackrabbits or in deserts inhabited by cactus, kangaroo rats, and rattlesnakes. As long as it was not in direct competition with the wolf, the coyote ranged from the Sonoran Desert to the alpine regions of adjoining mountains or the plains and mountainous areas of Alberta. With the extermination of the wolf, the coyote's range expanded to encompass broken forests from the tropics of Guatemala and the northern slope of Alaska.
Diet
The coyote is ecologically the North American equivalent of the Eurasian golden jackal. Likewise, the coyote is highly versatile in its choice of food, but is primarily carnivorous, with 90% of its diet consisting of meat. Prey species include bison (largely as carrion), white-tailed deer, mule deer, moose, elk, bighorn sheep, pronghorn, rabbits, hares, rodents, birds (especially galliformes, roadrunners, young water birds and pigeons and doves), amphibians (except toads), lizards, snakes, turtles and tortoises, fish, crustaceans, and insects. Coyotes may be picky over the prey they target, as animals such as shrews, moles, and brown rats do not occur in their diet in proportion to their numbers
In folklore and mythology
Coyote features as a trickster figure and skin-walker in the folktales of some Native Americans, notably several nations in the Southwestern and Plains regions, where he alternately assumes the form of an actual coyote or that of a man. As with other trickster figures, Coyote acts as a picaresque hero who rebels against social convention through deception and humor. Folklorists such as Harris believe coyotes came to be seen as tricksters due to the animal's intelligence and adaptability. After the European colonization of the Americas, Anglo-American depictions of Coyote are of a cowardly and untrustworthy animal
Prior to the Spanish conquest of the Aztec Empire, Coyote played a significant role in Mesoamerican cosmology. The coyote symbolized military might in Classic era Teotihuacan, with warriors dressing up in coyote costumes to call upon its predatory power. The species continued to be linked to Central Mexican warrior cults in the centuries leading up to the post-Classic Aztec rule.
