human encroachment

roombavoomba  asked:

What is the deal with seagulls, have they always been opportunistic around humans? I live about 15 miles inland and seagulls would always show up at our schools around lunchtime and could get pretty aggressive over the trash and dropped fries for instance. Crows and finches do the same thing, but the seagulls seem like something is wrong with their natural environment that worries me. That or they just know humans have food

Seagulls are a really great example of what happens when you have a combination of habituation and the ability to adapt well to an urban environment. They’re naturally scavengers with good memories and the ability to fly long distances in search of food - now add in human encroachment on their coastal habitat, human habitations that mimic their nesting sites (sheer edges and flatish roofs) lack of natural predators in cities, and the picnics that come with our beach days and you’ve got a great recipe for a species realizing that it’s way more effective to chill out and utilize humans as a source of food. We’re so many generations into that pattern that they’ve learned how to scout for food-rich areas and time their visits. So it’s not really that there’s something wrong with their natural environment, more that they’ve really adapted to cohabitation with us as their new “natural” state in urban areas. 

(…thinking about it, this is actually probably the closest example I’ve seen to how people think proto-wolves might have started the evolutionary journey into becoming dogs. Hanging out around human settlements for the food, slowly adapting across generations for lower flight distance, and eventually learning to utilize us as a resource…)

The Extinct Thylacine or Tasmanian Tiger

The Thylacine was the largest known carnivorous marsupial of modern times.  It is commonly known as the Tasmanian tiger (because of its striped lower back) or the Tasmanian wolf.  Native to continental Australia, Tasmania and New Guinea, it is believed to have become extinct in the 20th century.  It was the last extant member of its family, Thylacinidae;  specimens of other members of the family have been found in the fossil record dating back to the late Oligocene.

The Thylacine had become extremely rare or extinct on the Australian mainland before British settlement of the continent, but it survived on the island of Tasmania along with several other endemic species, including the Tasmanian Devil.  Intensive hunting encouraged by bounties is generally blamed for its extinction, but other contributing factors may have been disease, the introduction of dogs, and human encroachment into its habitat.  Despite its official classification as extinct, sightings are still reported, though none has been conclusively proven.

About the video:  Compilation of all five known Australian silent films featuring the recently extinct thylacines, shot in Hobart Zoo, Tasmania, Australia. Benjamin, the last specimen, is shown in the footage starting from 2:05.  The clips are separated by fades.

This is a ghostly web-footed gecko, they can be found and perfectly camouflage among the powdery reddish sands of the Namib Desert, their primary habitat.These geckos have adapted their webbed feet not only to help them stay atop, but to bury beneath the dunes of the Namib Desert. Strictly nocturnal lizards, they spend the day in self-dug burrows and emerge at night to feed.

Their bloodshot-looking eyes are massively oversized to help them detect prey, which includes crickets, grasshoppers, and small spiders. They move surprisingly quickly across the sand, and adhesive pads on their toes make them excellent climbers.

People sometimes hunt these tiny lizards for food, and human encroachment is destroying some of its habitat. Their estimated lifespan in the wild is about five years.

I Don’t Want Freedom!

‘Government exists to protect us from each other. Where government has gone beyond its limits is in deciding to protect us from ourselves.’
                - Ronald Reagan

Following the 9/11 terror attacks, it became increasingly more and more popular to believe that greater emphasis should be placed on security, perhaps even requiring sometimes to exchange certain liberties to ensure security.

Naturally, when people are told that they cannot exercise complete free will and are limited in what they can do and where they can go/travel, this faces much criticism and many a complaint, arguing that tradeoffs such as these encroach on human rights. According to Henry Shue, security itself should be seen as a basic human right and not only this but as a precondition upon which other human rights can be enjoyed. For instance, if I have the right to vote for whoever I wish, but there was a threat that had I voted Trump I would get beaten up, I would be unable to exercise my right to vote IF there is no guarantee of security.

IT SEEMS NECESSARY THEN THAT THERE IS SOME COMPROMISE BETWEEN LIBERTIES AND SECURITY.

However, taking this into account, if we ask what it is that terrorists hope to achieve through their acts, there are two options

  1. cause death and wreak havoc
  2. scare governments and spread fear

Of course, it is true that they do 1. but it is also true that in their acts they hope to create a state of urgency and fear in the society attacked, normally to bring about change of some sort - to alter the freedoms that the society practices and replace them with others. If the government is to take away certain rights and freedoms to ensure security, then ’that would be to postulate the very same thing (the taking away of rights by the state in the face of terrorist attack) as both the problem and the solution (Waldron, Security as a Basic Right).

I decided to hop on the Pokemon variations because I’m biology and Pokemon trash and headcanons for subspecies and species variations of Pokemon are both those things.

But really, I haven’t seen too many Pokemon variations for Joltik. Which is sad because guys, c’mon, spiders. I mean think of how diverse spiders are in appearance and behavior. imagine the possibilities. 

I’m not much of an artist but I chose five different spiders (their name written under) as subspecies of the standard (cave Joltik) to draw with the habitat their suited for written below them and i also wrote some headcanons to go along with them. 


Pink Fairy Joltik (Garden): A variation of the standard Joltik that was discovered only very recently, this subspecies is slightly smaller than the rest of its cousins and has adapted camouflage to disguise itself as a part of a flowering plant. As humans encroached on their natural habitat they quickly adapted to live alongside and were discovered soon after. Part of their diet consists of parasitic insects and pest, making them a welcome guest in any garden. This subspecies is popular among Pokemon Breeders and Pokemon Competition Trainers for its gentle demeanor and attractive colors and markings. 

Bridge-Builder Joltik (Forest): One of the most common subspecies of Joltik that’s versatility allows it to live in almost any wooded environment. An orb-weaver bug type that builds some on the largest webs in the world, it exhibits a unique behavior of building bridge-like web structures to get across bodies of water. The silk of the Forest Joltiks is one of the toughest biological materials found. The threads of silk are ten times tougher than similar sized pieces of Kevlar, the man made material used in bullet proof vests and is currently being studied by engineers and biologists for the possibility of being harvested and used by humans. 

Boulder Joltik (Mountains): The largest of all subspecies of Joltik. Known as the “Rock Climber Pokemon” it can scale any type of surface, even glass. They possess an extra set of legs used for scaling rocks and jumping on to high ledges. The texture of its hair its bristly, course, and tough and acts as an extra layer of protection adapted for harsh environments. Because of its strength and size it is popular with Pokemon Battle trainers. 

Clown Joltik (Tropical Climates): The tropical Climates Joltik, or Clown Joltik as they are better known. Live in tropical climate zones in habitats such as wetlands and rain-forests. They live beneath the leaves of plants and the markings on their backs are to frighten potential predators away. To humans, their markings appear to be a grinning face. popular legend says if someone comes across this Pokemon, it means that joy and good fortune will come your way soon.

Golden Joltik (Safari Zone): Golden Joltik are a critically endangered subspecies of Joltik, driven to near extinction by deforestation and black market trade for their silk, the can only be found in Safari Zones today. The webs they spin have a shimmering reflective color and almost appear to be spun out of pure gold. They are increasingly shy and as a protected species it is illegal to disturb their webs or capture them. 

Bonus: Trapdoor Joltik

It’s Fandom Favorites week for our Summer Spectacle winning team, Falcon Helldiver!! This week we’re featuring pieces you might already recognize, but are well worth a second look.


The One Where They Adopt a Selkie [T] [7737]

“That’s a kid,” Stiles said.

Derek growled. “It’s a selkie.”

“It’s a selkie kid,” Stiles pointed out, because really, they did not need to be arguing semantics right now. “Do selkies just go around leaving their kids sleeping in caves on the beach?”

To See With Eyes Unclouded [E] [47770]

Cursed by a dying god, Derek seeks help from the great wolf Satomi. She lifts the curse with a Bite, but Derek can never leave the forest, lest the curse return.

Taken in by Satomi’s small pack, Derek finds himself learning more about the forest and navigating an antagonistic relationship with Stiles, Satomi’s only human child.

But darkness encroaches at their borders as the humans of Irontown delve deeper into the forest in their quest for iron, and the bad blood between the wolves and the humans threatens to breach the point of no return.

And Derek may well be the only one who can pull them back from the brink.

Happy Birthday Mr. Hale [Series]

Derek is a single dad. Stiles is the college student who’s been babysitting his daughter for the past three years. Smut ensues.

The Rest Is Unwritten [T] [6267]

Once upon a time, the werewolf king and queen invited five fairies to the christening of their only son. The fairies bestowed the boy with gifts—beauty, grace, wit, and the most adorable teeth in all the land.

But before the fifth fairy could give her gift, a wicked fairy from the other Court arrived and cast a terrible curse on the baby prince. He would have a life full of tragedies, she declared, and die young, of a broken heart.

The king and queen were beside themselves with grief. It was very old, powerful magic, so there was little they could do to break it. However, the fifth fairy had yet to give her gift. The curse could not be broken, she told them, but it could be altered.

She bestowed upon the prince the gift of perseverance, so that he would never lose his will to live, even in the face of countless tragedies. And when he found the one who would stand by his side and face those tragedies with him without fail, that is when the curse would be broken. Because the fairy knew there was nothing in all the world more powerful than true love. Not even a wicked fairy’s curse.

While You Were(n’t Quite) Sleeping [T] [13568]

Scott’s mom, Melissa, had given Stiles the basics on Derek’s condition when he’d first come over here a month ago. Derek had been here six years, the only survivor of a horrific house fire that had killed the rest of his family. It had left him burned, half his face puckered with scars, and he’d been in a catatonic state the entire time. Stiles couldn’t even begin to imagine how awful that would be, being trapped in your own body for years on end, all alone.

Stiles had an inkling of how much being alone sucked, anyway.

(An AU in which Derek is the one who was trapped in the fire, and then in the hospital, based on a set of pictures from littlecofiegirl.)

A Desperate Arrangement [E] [115506]

“I’m sorry, I believe there’s something wrong with my hearing,” Stiles said. “Because I could have sworn you just told me you set up a betrothal agreement with the Hales. A betrothal agreement involving me. Me.”

Scott smiled his easygoing smile and nodded, which told Stiles no, he hadn’t misheard a damn thing.

After seven years of lengthy negotiations, the treaty between the Hales and the Argents has fallen apart and the two countries fell into war.

Months later, there’s an uneasy truce, thanks to the intervention of King Scott McCall, but it won’t last. In a desperate attempt to maintain the peace, the Hales sign a treaty with the McCalls to marry Prince Derek to Prince Stiles Stilinski, King Scott’s brother.

In the history of the world, there have been many better ideas.

The Man in the Snow [T] [15894]

Derek finds a young man injured in a ravine on the border of his ranch. That’s strange enough, but the mystery only deepens when the young man wakes up without any memory of what he was doing out there.

The Christmas Raffle [E] [10386]

Every year, the royal Hale family raffles off a Christmas dinner with Prince Derek to raise money for charity. But this year, the winner is the second chance Derek didn’t know he was looking for.

See Derek Date [E] [20699]

When Derek sees his ex-boyfriend, Jordan, for the first time in ten years, he tells a little white lie about his love life (or lack thereof). Of course, that all blows up in his face when his sister Cora finds out and demands that Derek bring his (imaginary) boyfriend to her wedding.

Now he’s got one month to change that “imaginary” boyfriend into an actual one.

A Wild Heart’s Desire [T] [13410]

If there’s one thing Stiles Stilinski knows, it’s that Deputy Derek Hale absolutely Does Not Like him. The only reason Derek even tolerates him is because their kids are worryingly codependent.

So Stiles is understandably confused when a very feral Derek shows up in his backyard after a call gone wrong and proceeds to move in with him.

            * “I fear you have made a mistake in coming here,”

            His smile was thin, and wan, too perfect (too deliberate) to be genuine. the looming monster turns to greet the encroaching human, swaddled in the gloom of his laboratory as though the darkness threatened to envelop him entirely.

       * “ . .This is no place for a human being.”

Greater Prairie Chickens have evolved incredibly complex auditory organs through millenia of predation. Featuring swiveling auricles, inflatable amplification chambers, and removable micro-SD storage, these birds are capable of hearing a human footfall from a distance of three Canadian football fields. Despite their amazing perception, these birds are listed as Vulnerable by the IUCN due to human encroachment on their traditional territory.
