Hello To All My Loyal Readers:
As promised, I will be emailing you with announcements of my new blogs every other week. On the alternate weeks, I will share the URLs to some articles by others that I found interesting. Here is a list of some recent articles that I’ve read.
“We need another and a wiser and perhaps a more mystical concept of animals. Remote from universal nature and living by complicated artifice, man in civilization surveys the creature through the glass of his knowledge and sees thereby a feather magnified and the whole image in distortion. We patronize them for their incompleteness, for their tragic fate for having taken form so far below ourselves. And therein do we err. For the animal shall not be measured by man. In a world older and more complete than ours, they move finished and complete, gifted with the extension of the senses we have lost or never attained, living by voices we shall never hear. They are not brethren, they are not underlings: they are other nations, caught with ourselves in the net of life and time, fellow prisoners of the splendor and travail of the earth.”
Research from the National Science Foundation reveals that the Yellowstone ecosystem needs beavers as well as wolves and elk. Restoring the wolf population isn’t enough to reverse the extensive changes caused by their long absence. Everything is interconnected and all of the connections need to be restored. An understanding of how species interactions cascade through food webs is essential if we are to restore ecosystem resilience. Take a look at these two URLs
Wolves will kill for more space. A new study involving Logan’s Utah State University and University of Oxford found wolves will fight to the death to protect their turf if they lack adequate space to raise their pups. This study produced a generally novel result because the conventional thinking is that large carnivores are limited by the abundance of prey in a given area. But what these wolves are ultimately limited by is the amount of space they have to raise their pups in safety.
Dan MacNulty, USU ecologist said that:
“Wolves killing wolves is their No. 1 cause of death in Yellowstone and MacNulty said the research showed that adult survival rates dropped below 70 percent if there were greater than 65 wolves per 1,000 square kilometers. These key observations in wolf infanticide may provide helpful lessons for management of wolf populations because of the insights they deliver”
“For those concerned about wolf populations, even when you have super abundant prey like in Yellowstone, there are limits to wolf population growth. There is an intrinsic limit to the number of wolves that occupy a given space,”
MacNulty added that because rival packs will attack and kill rival wolf pups, their numbers are self-limiting.
My name is Bill Graham. As a Marine Biologist who has worked in the US and Mexico for 30 years, I am a student of Nature, a teacher, a researcher, and a nature photographer. Through my work, I have acquired an ever growing passion for how everything in Nature is connected. Today, I travel extensively contemplating about, writing about, and photographing Nature’s connections. I also work with conservation projects in the USA and Mexico and mentor talented youth.
