While this topic does not directly relate to animals or our pets, I felt it was important to post. House fires can kill both people and pets. Please check out the link. House fires can cause forest fires and harm wildlife. Thank you to Wes Keller DCNR for sending me this link.
In a revealing study conducted by the University of New South Wales, Dr. Kylie Cairns a biologist found that contrary to popular belief, there are few wild dogs and Dingo hybrids in Australia. The study showed that 99% of the 5000+ animals tested, were pure Dingoes or if they were hybrids, were mostly Dingo and not dog. Only 1% were wild dogs or dog dominant hybrids.
Some groups refer to Dingoes as wild dogs and try to kill them. The researchers feel that if Dingoes are called Dingoes, the groups that are in favor of destroying them will change their attitude. Because Dingoes come in a range of colors, it can be difficult for people to identify a Dingo and mistake it for a wild dog.
Research has found that by killing Dingoes, the local ecosystem is harmed. The Dingoes keep the herbivores and smaller predators under control and thus keep the environment balanced. When the Dingoes are removed, the Kangaroo population grows which leads to overgrazing and causes damage to the soil.
Only the Victoria National Park in Australia protects Dingoes. Elsewhere they are hunted by dropping aerial bait to kill them. Farmers do complain that their livestock is harmed by Dingoes so a means of protecting farm animals is necessary.
DNA has been collected in various way, including soil and water, now scientists have proven that environmental DNA (eDNA) can be collected from the air.
Both plants and animals shed DNA in the environment that they interact with. Dr. Elizabeth Clare, of the Queen Mary University in London has stated that ecologists and conservationists are always looking for non-invasive ways to monitor biological environments, collecting DNA from the air provides one way to do this.
An added benefit to monitoring eDNA is that it will allow researchers to study the transmission of airborne diseases. What the study does not mention is how long the eDNA exists in the air. However, it is an interesting and beneficial step in the right direction that will benefit the health of all living things.
Bats have had a significant decline in the past few years due to white nose syndrome. As a result, many people have done what they could to help bats repopulate. Bat ecologists Joy O’Keefe and Reed Crawford at the University of Illinois, have conducted a study to see how beneficial bat boxes are in helping repopulate bats.
They found that the common bat boxes that many people use may actually be harmful to bats. Many of the flat-paneled boxes with slats often get too hot for the bats and do not allow them to move away from the hot area. This is especially true of the boxes are painted a dark color.
If you want to put up a bat box, they suggest a four-sided box that gives the bats freedom to move all around the inside. Even with a better bat box, the placement is also critical. Do not put the box where it will get direct sun all day. The area where the bat box is located should be safe for bats, protecting them from predators, away from roads, and free from parasites.
What home owners can do is plant native trees and wildflowers that attract the insects that bats eat. Provide a clean water source and leave dead standing trees, which are natural roosting areas for bats.
As we approach Passover and Easter, it is a good time to reflect on the impact and role that animals have in God’s plan. From the very beginning, in the Garden of Eden, God used an innocent animal to represent His saving Grace.
When Adam and Eve sinned, they tried to fix their sin themselves by making aprons of fig leaves to cover their nakedness or sin. But God showed them that only God can forgive or fix sin. To do this He killed an animal and made them clothes of the animal’s skin. From that point on the Jewish people had to sacrifice an animal on the Day of Atonement to cover their sins for a year. This animal sacrifice represented the coming of the Messiah.
When the Angel of Death visited Egypt, those people who had the blood of the lamb on their door posts were passed over. Did you realize that their animals were also spared?
Scientists have long pondered the mental abilities of animals. Recently they have designed tests to determine just how smart and how aware animals are. If they had carefully read the book of Numbers, they would have had their questions answered.
The Bible teaches us kindness to animals, how they think, which animals were created to be domesticated and which ones were not. It also talks about miracles that involve animals.
Jesus is referred to as the Lamb of God. When he died and was raised from the dead, there was no longer a need to sacrifice animals, the debt had been paid. Have you ever thought of the fact that only an animal is innocent and pure enough to represent the Messiah?
If you want to read more about the role of Animals in the Bible, you can do so in my book, God’s Creatures: A Biblical View of Animals. There is so much the Bible teaches us about them. You will be amazed. You can order a signed copy at http://www.sbulanda.com
According to retired anthropologist Pat Shipman from Penn State University, dingoes and their closely related New Guinea singing dogs, are not dogs. They are not wolves either, but fall into their own class.
Domestic dogs arrived in Australia in 1788 with the first ships of convicts. The dingoes were already there for at least 4000 or more years prior to that. Genetically and behaviorally, they are more like wolves with their inability to digest starches and their inability to bond with humans. Dogs on the other hand have no difficulty digesting starches and do bond with people.
Dingoes can survive in the Australian outback where domestic dogs that are feral have a difficult time or cannot survive.
What makes it difficult to separate the lines between wolves, dogs and dingoes is that genetically they can hybridize and have fertile offspring unlike horses and donkeys who typically produce infertile mules.
Shipman feels that a dingo is a wolf on its way to becoming a dog but never made it.
It has long been thought that wolves hunting methods only involve running down large prey until they are too exhausted to fight. However, new research has shown that wolves have developed a stalk and ambush method of hunting in the summer, designed specifically to catch beavers.
Beavers have poor eyesight but a keen sense of smell. Wolves have learned to wait downwind from where the beaver comes out of the water to go on land.
Researchers found that this hunting method is not limited to a few wolves, but has spanned several years through multiple packs over the Northern Hemisphere where wolves and beaver co-exist.
The study shows that wolves are flexible in their hunting methods and can change to the method that works at that time.
Author Note: This also demonstrates the wolf’s intelligence and ability to communicate the method to other members of the pack.
A new study by Global Ecology and Biogeography with lead researcher Daniel Becker, a postdoctoral fellow at Indiana University developed a model that identified, with an 80% accuracy, the species of birds that spread Lyme’s Disease. They found 21 new species that spread the disease.
The research team found about 102 other studies that showed Lyme disease infection from ticks feeding on the birds. There were 183 species of birds that infect the ticks with Lyme’s. The birds have a broad range that spans the Americas, Africa, Asia and Oceania.
What this means is that even though the birds do not spread Lyme to people, the ticks on them can drop off of the bird into a garden or yard and then attach to a person. Because birds can fly great distances, they can spread Lyme’s disease to areas that previously did not have it or did not have a lot of it.
The study found that thrushes are the riskiest bird as well as perching birds and those that eat seeds and forage on the ground.
Author’s note: Tick activity is always the strongest in the spring and fall where there are definite seasons. Always take precautions when outside, especially wearing long sleeves, long pants with your socks over the cuff of your pants. This prevents ticks from crawling up your pant legs. Use bug repellent and cover your head. After working outdoors, remove and wash all clothing and be sure to check your entire body for ticks.
A recent study illustrated that Zebra finches can recognize the song or call of at least 50 members of their flock. They use this ability to find a lost member or to call and see if it is safe to return to the nest.
They need this ability because they usually travel in colonies of 50 to 100 birds and they split up and then come back together. They have distance calls that they use to identify where they are and to find members of the flock.
While it has been known that songbirds are capable of communicating sounds with complex meanings, the latest research shows that songbird brains are capable of complex vocal communication. This also reflects on their high level of intelligence. Imagine how smart other animals are.
When people think of animals being struck by aircraft, birds come to mind. However, researchers have studied how many mammals were hit by aircraft. They found that worldwide, mammals hit by aircraft have increased by 68% world-wide. The range in size was from voles to the giraffe and everything in-between.
In the United States alone, damage to aircraft over a thirty-year period was 103 million dollars. Most of the animal strikes occurred during the landing phase of flight. Typically, the take-off and landing of an aircraft are the riskiest times. The study did not suggest how to alleviate the risk of hitting mammals.
