Wildlife encroachment

For centuries, human activities such as hunting and encroachment have made life difficult for the largest species, from mammals and fish to insects and trees, leading to an evolutionary trend towards the miniature. While research into the diminution of non-human life on Earth has been steeped in academic study, the logic behind the phenomena is actually quite simple.

The largest animal specimens, like deer, are typically the most targeted by hunters -- which results in fewer big deer to pass their largeness genes to a new generation. Naturally, such a selective process would dictate deers grow smaller over time, or else face a greater threat to the species itself.

In fact, few of the largest animals on Earth, megafuana, have not been impacted by us. More than 25, years ago, one megafaunal species Wildlife encroachment we humans -- began to spread rapidly around the globe and in the process helped to wipe out about half of all land mammals weighing more than 44 kilograms.

Among the victims were whole groups of mammoths, mastodons, saber-toothed tigers, giant ground sloths, and big beavers.

Many vanished in just a 4, year span that ended about 11, years ago. By then, Australia had lost roughly 88 per cent of its big mammal groups, South America 83 per cent, and North America 72 per cent. Africa did better during what is now called the Quaternary Megafauna Extinction QMElosing about one-fifth of its big species, while Eurasia lost one-third.

Shrinking or altered habitats, due to human development, tend to signal smaller inhabitants.

Some pants also may be feeling the effect of human-selection. Historically, the biggest trees are often the first to be cut down -- a fact which may have inadvertently worked to weed-out the gene for big growth.

Researchers have noted a shortage of big fish species as fisheries target the meatiest specimens while returning the leanest. The Head of the Ocean Sciences program at the U.

Researchers say that smaller creatures tend to be the most resilient to many habitat changes, and that the loss of their larger predators may actually be a boon to them -- but this may matter little if changes in weather patterns come about as climatologists have warned.

In light of a future which may hold smaller wildlife than we know today, it is important to note that the opposite is likely true for us -- and the two factors are hardly unrelated. Obesity rates in humans continue to skyrocket as our lives become more sedentary in carbon-spewing motor vehicles, our food sources become more remoteand as it takes more encroachment into natural areas to accommodate us and all of our stuff.

Help Save Wildlife. By as many as one fifth of all animal species may be lost, gone forever. In recent times, hundreds of species have become extinct as a result of human activities.

Sea turtles have existed for million years and yet the species living today face an uncertain future. Habitat encroachment and degredation, pollution, incidental capture in commercial fisheries, and strikes by watercraft are only some of the hazards sea turtles must face as each species struggles to stay alive.

This book brings together information on the contrasting characteristics, condition, present use and problems of the world's main natural grasslands.

Since grassland is commercialized through the grazing animal, particular attention is paid to the livestock production systems associated with each main type. Grazing resources are more than simply edible herbage: many other factors have to be.

From focusing our efforts on landscapes to reducing wildlife trade, WWF's global tiger programme (Tx2) is all about doubling the number of tigers in the wild.
