An Australian conservation group has been forced to retract published research on the discovery of an endangered bird.
A wolf pack is roaming wild in Denmark for the first time in more than 200 years after a young female wolf journeyed 500km from Germany.
Male wolves have been seen in Denmark since 2012 and the new female could produce cubs this spring in farmland in west Jutland after two wolves were filmed together last autumn.
It is further evidence that the wolf is returning to well-peopled landscapes after centuries of persecution, with wolf packs also re-establishing themselves in France and Germany and individuals sighted in Holland and even Luxembourg. Before the new population, Denmark’s last wolf was killed in 1813.
Mexican authorities have announced plans to save the vaquita porpoise after an official report found just 10 of the elusive creatures remain. The environment department said it would mark out a reserve for the planet’s most endangered marine mammal, while also boosting the local economy. But with the vaquita now on a “final countdown to extinction”, conservationists warned that such efforts were too late to save the porpoise. A recent report by the International Committee for the Recovery of the Vaquita (CIRVA) concluded there were just a handful of the animals left in the Gulf of California, their final refuge. True numbers may in fact be even lower than their estimate, as the campaign group Sea Shepherd has since announced the discovery of a body they believe to be a vaquita trapped in an illegal net.
Ten left. Better late than never but could this not have happened sooner?
Since only the sun and moon made light, I have known you. I watched you from the once vast, impenetrable forest. I was witness as you discovered fire and strange tools. From ridges, I watched you hunt, and envied your kills. I have eaten your scraps. You have eaten mine.
I have heard your songs and watched your dancing shadows around bright fires. In a time so distant that I can barely remember, some of us joined you to sit near those fires. We became part of your packs, joined in your hunts, protected your pups, helped you, feared you, loved you.
We have existed together for a long time. We were much alike. It is why the tame ones adopted you. Some of you, I know, respected me, the wild one. I am a good hunter. I respected you, too. You were a good hunter. I would see you hunt in a pack with the tame ones and catch meat.
Then there was always plenty. Then there were few of you. Then the woods was big. We howled to the tame ones in the night. Some came back to hunt with us. Some we ate, for they had become very strange. It was this way for a long long time. It was a good way.
Sometimes I would steal from you, as you did from me. Do you remember when you were starving and the snow was deep and you ate the meat we killed? It was a game. It was a debt. Some might call it a promise.
Like many of the tame ones, most of you became very strange. Now I do not recognize some of the tame ones. Now I do not recognize some of you. We were once so much alike. You made the meat tame, too. When i began to hunt your tame meat (they are foolish creatures and do not honor death, but the wild meat was gone), you hunted me. I do not understand. When your packs grew larger and fought among themselves, I saw. I watched your great battles. I feasted on those you left behind. Then you hunted me more. I do not understand. They were meat. You killed them.
We wild one are now very few. You made the woods small. You have killed so many of us. But I still hunt, and I feed our hidden pups. I always will. I wonder if the tame ones who live with you made a good choice. They have lost the spirit to live in the wild. They are many, but they are strange. We are few. I still watch you, too, so I can avoid you.
I do not think I know you any longer.
Non-muscular locomotion involves the use of cilia and flagella. These are long and narrow cytoplasm extensions that can move and bend, generally a wave-like motion going down the flagella is used to move the organism and a stroke like movement (pushing out) used with cilia. Organisms that use this form of movement for locomotion are generally small in size.
The heart of a frog only has three chambers (the left atrium, right atrium and ventricle). So, deoxygenated and oxygenated blood is separated in the atria, however there is potential for mixing in the ventircle (located below the atria).
We made a new friend today 🤖 this installation by Ian Cheng presents the United States premiere of his artificially intelligent artwork, BOB (Bag of Beliefs). What does it entail to collect, let alone preserve a work of art when it is an artificial life form? The exhibition closes in two days — highly recommended.
“Glimpse of Grandeur”
On Tuesday I attended a Talk at the Zoo hosted by Dr. Gregory Rasmussem, who founded the Painted Dog Conservation. He has been working with the Species and the people of Zimbabwe since 1988 and could be considered the expert on the Species. He was fascinating to listen to and meet.
Painted Dogs are a wonderful species with a very rich social structure. They are extremely successful hunters with a success rate of 60%+ to 90%. To put that in perspective a Lion’s success rate is 17%-19%. They are very fast and coordinated which is why they have this success rate.
The are also endangered with roughly 6,600 of them known to be in the world. The biggest threat to them is the false perception they are vicious wild dogs which kill livestock. Another is hunters and poachers who leave snares out. These snares are not intended for Painted Dogs but can catch them nonetheless.
A program the Conservation has setup is educating the youth on the importance of Conservation of wildlife. This has led to a lot of kids exploring the nearby wilderness and locating these snares. They are then disarmed. These kids have also been making these neat little sculptures out of the snares as a way to repurpose them into something much more positive.

An incredible insight to behind the scenes of Seaworld’s Orca program. It shows the torment and pain these intelligent animals go through and how this can turn south not just for the animals but the trainers around them.
I always believe most people who work with animals do love them and I do think most of the trainers here got into the industry loving animals and just wanted to work with them but you come along with them to see exactly what goes on at Seaworld , the conditions of their captivity and the toll it takes on the orcas both mentally and physically.
Easily one of the best documentaries I have ever seen. You can see it HERE!
Lion bones, leopard skulls and an ottoman chair’s elephant leather were among the body parts of endangered animals imported into the UK by trophy hunters through a loophole in international law in 2018, the Guardian can reveal. The government is facing renewed calls to ban trophy hunting imports of endangered species after 74 rare animal body parts were legally brought into the country by hunters last year, including hippopotamus teeth, elephant ears and crocodile skins. Campaigners have said the African lion parts imported from South Africa last year probably came from lion farms, where animals are bred specifically for trophy hunters and to meet rising demand for traditional medicine ingredients in Asian markets.
Conservators at the Brooklyn Museum examined and analyzed the fabric in this egúngún masquerade dance costume before going on display in One: Egúngún. This type of costume is found throughout the Ọ̀yọ́ region of southwestern Nigeria. When worn, the costume conceals the wearer to embody the spirit of the ancestral dead and transform the wearer into a returned ancestor. A long wooden beam, which rests on top of the wearer’s head, is draped with many textile panels suspended in layers.
This costume’s densely layered textile panels are incredibly varied. They include both natural and synthetic fibers, hand-woven and factory-made weave structures, many dyed colors and printed patterns, and a number of metal appliques. The natural fibers, such as cotton and wool, are primarily found on the inner layers. The synthetic fibers, located mostly on the outer layers, include patterns of velvet and faux fur in bright colors.
Recent research has demonstrated that this costume was made sometime between 1920 and 1948. The curator wondered if any of the synthetic textile panels might be recent replacements or additions made with newer materials that didn’t yet exist at the time of manufacture.
Conservators at the museum identified the fibers using Polarizing Light Microscopy (PLM), a contrast-enhancing technique used to investigate optical properties of samples. PLM uses polarizing filters to configure the movement of light waves, forcing them to vibrate in a single direction. The polarized light interacts with the sample in specific ways depending on the material, which allows for identification.
We took samples of the different synthetic fibers and examined each of them under a polarizing light microscope, looking for defining characteristics such as shape and form, or how the fibers refract light. In the image below, showing fiber samples from this costume, you can see that acetate fibers appear yellow when oriented in one direction and blue when oriented in the opposite direction.
All of the velvets and faux fur we sampled turned out to be a combination of natural silk and synthetic viscose rayon and acetate. Both of these synthetic fibers were already in use in the early 20th century, which means these textile panels could be original. This information lets us better understand the piece, its history, and the conditions in which it was made and used.
The egúngún masquerade dance costume will be displayed in One: Egúngún through August 18 so make sure to see it in person!

May or may not have been MIA for the past few days, really sorry! But moving on!
I have another project in the works! I’m so excited! It seems like a really boring project, but I kind of can’t wait to write the report (weird I know)?
We have to investigate competition between a set of plant species given and write a report and do the stats etc.
We have decided to investigate the inter and intraspecies competition between wheat and millet seeds. We have set ratios (and four repetitions of each) at different concentrations (wrong word? but brain not working).
We have seed totals of 10, 40 and 70 in which we have ratios (e.g. 10:0, 7:3, 3:7 and so on for each seed total) that we’ll repeat four times. We have a random selection of pot placement (not random BOX selection as indicated by our demonstrator and lecturers multiple times) using a good old randomly found random number generator off the internet.
I meant to take pics last lab, but forgot, whoops. Also, I no longer have a reasonable camera/phone camera with which to take pics so all are blurry, you’re welcome.
I’ll try and keep you updated as much as possible and will attempt to take some pics next time!
