Plants Hear and Respond

12-IMG_3490 Caterpillars on a Grape Leaf

“Previous studies have suggested that plant growth can be influenced by sound and that plants respond to wind and touch. Now, researchers at the University of Missouri, in a collaboration that brings together audio and chemical analysis, have determined that plants respond to the sounds that caterpillars make when eating plants and that the plants respond with more defenses.

“Previous research has investigated how plants respond to acoustic energy, including music,” said Heidi Appel, senior research scientist in the Division of Plant Sciences in the College of Agriculture, Food and Natural Resources and the Bond Life Sciences Center at MU. “However, our work is the first example of how plants respond to an ecologically relevant vibration. We found that feeding vibrations signal changes in the plant cells’ metabolism, creating more defensive chemicals that can repel attacks from caterpillars.”Appel collaborated with Rex…

Why Animal Rights?

GarryRogers's avatarGarryRogers Nature Conservation

Almost all of us grew up eating meat, wearing leather, and going to circuses and zoos. Many of us bought our beloved “pets” at pet shops, had guinea pigs, and kept beautiful birds in cages. We wore wool and silk, ate McDonald’s burgers, and fished. We never considered the impact of these actions on the animals involved. For whatever reason, you are now asking the question: Why should animals have rights?

“In his book Animal Liberation, Peter Singer states that the basic principle of equality does not require equal or identical treatment; it requires equal consideration. This is an important distinction when talking about animal rights. People often ask if animals should have rights, and quite simply, the answer is “Yes!” Animals surely deserve to live their lives free from suffering and exploitation.

“Jeremy Bentham, the founder of the reforming utilitarian school of moral philosophy, stated that…

Carlsbad Caverns Guided Tour

250 million years ago, the Guadalupe Mountains — in what is today known as New Mexico, U.S. — were the ancient shoreline of a vast inland Sea that covered a great area of plains states. Today, much of New Mexico is covered with parched desert lands, though there are many features in this land that are still remnants of that long lost sea. The Carlsbad Caverns are one of the most impressive features created by the retreating waters from long ago. The caverns are an immense series of single caves, or “rooms,” which follow the path of the original water’s retreat through the hard limestone and soft clay and dirt. Not only is this one of the largest cave systems that has been discovered in America, the details of this system of caves is what sets it apart from any other.

The Common Grass Yellow Butterfly lives up to its name. Found throughout all of India, this lepidopteran flies low and close to the ground in fields, and its wings are a pretty yellow with some subtle patterning. Their larvae feed on several different plants, but generally in the families of the spurges and legumes.

INDIA: A few weeks ago, jallikattu was banned and a long battle won

This bull, and those below are not jallikattu bulls; they were rescued by Blue Cross of India from illegal transport. This bull, and those below, are not jallikattu bulls; they were rescued by Blue Cross of India from illegal transport.

In a milestone victory in the fight for animal protection, jallikattu is now permanently banned.

Jallikattu, or the “sport” of bull-baiting, took place mostly in the Indian state of Tamil Nadu. The events were cruel and subjected the bulls to being tormented by crowds of young men attempting to tackle them. Behind the scenes, bulls were tortured in order to get them to run, since bulls do not naturally run the way horses do. Many Indian animal groups worked hard against jallikattu, notably Blue Cross of India, which fought an uphill battle for more than five decades to have jallikattu banned.

On May 7, 2014, jallikattu, was banned by the Supreme Court of India.

A May 13, 2014, editorial in The Hindu states that the Supreme Court ban of jallikattu…

Still 28 March 2014 in San Gerardo de Dota in Costa Rica. After the earlier birds of that day, hummingbirds: like this green violetear.

Nectar feeders and flowers attract hummingbirds; and a slaty flowerpiercer as well.

The hummingbird species include volcano hummingbird.

White-throated mountaingems were present as well.

And a relatively big species: magnificent hummingbird.

Yellowish flycatcher, 28 March 2014

Another Central American cool mountain forest species: yellowish flycatcher.

At 10:20, a swallow-tailed kite flies overhead.

We have to leave, to the Central Valley of Costa Rica.
