Welcome to Animal | Vegetable | Mineral

I never cease to be awed by the splendor of the natural world, by the forces that shape the earth, and by the diversity and ingenuity of the life that populates it.

Animal | Vegetable | Mineral is a group where those who share this fascination can discuss the Earth and animal sciences of geology, volcanology, seismology, ecology, ethology, primatology, entymology—basically all the –ologies of the natural world.

For cosmology, please post in The Daily Cosmos. For green living, sustainability, and environmental activism, please post in the Green Atheists group.

Bull Riding and breeding results in heartier breeds, unlike the cruelty of Bullfighting.

Fear of Predators in Grasshoppers

The fear of predators in an ecosystem can have a vast impact on soil ecology, simply due to the stress they put upon their prey. Dror Hawlena, ecologist at the Hebrew University in Jerusalem and his colleagues, showed that when stressed grasshoppers died, they impact their environment by the chemical differences in their bodies, affecting how the surrounding dead plant material is broken down by soil microbes.

The scientists published their findings in the journal Scienceand were interested in organism ecology and biogeochemistry. This allowed them to make predictions about how food web structure affects nutrient cycling.

Other studies have shown the impact of stress on animals, which will eat more carbohydrates to meet their heightened energy requirements. This in turn leaves a chemical trace in the bodies of the stressed animals. The nitrogen-poor corpses affect the metabolism of soil microbes, causing bacteria that require nitrogen to falter in the production of their decomposing enzymes.

Hawlena and his team reared grasshoppers in field cages with predatory spiders that had their mouths glued shut. When the grasshoppers died, the remains were examined in a lab. The samples were then added to leaf litter to see how quickly plant material would decompose by soil microbes.

The overall indirect effect of this predatory stress on soil microbes is lasting, and the rate of decomposition was 200% less than in samples treated with non-stressed grasshoppers. Predators actually affect soil microbe communities and the cycling of nutrients in more ways than just eating their prey.

The effects of this cascade isn’t immediately obvious, but this paper is added to the growing number of studies that detail the knock-off effects that predation has on organisms in an ecosystem, including soil fertility, plant growth and nutrition.

It’s also hard to speculate how losing apex-level predators will affect soil ecology and biodiversity globally, but predators have a dramatic effect on the biogeochemical processes in ecosystems.

This isn't the same as other life,

Trees, grass, aqua†ic life including amoebas and other living organisms communicate threats to their welbeing.

Question: Do Insects Feel Pain?

Scientists, animal rights activists, and biological ethicists have long debated this common question: do insects feel pain? It's not an easy question to answer. We can't know for certain what insects feel, so how do we know if insects feel pain?

Answer:

Pain, by definition, requires a capacity for emotion.

Pain = an unpleasant sensory and emotional experience associated with actual or potential tissue damage or described in terms of such damage.
– International Association for the Study of Pain (IASP)

Pain is more than the stimulation of nerves. In fact, the IASP notes that patients can feel and report pain with no actual physical cause or stimulus. Pain is a subjective and emotional experience. Our response to unpleasant stimuli is influenced by our perceptions and past experiences.

The insect nervous system differs greatly from that of higher order animals.

Insects lack the neurological structures that translate a negative stimulus into an emotional experience. We have pain receptors (nocireceptors) that send signals through our spinal cord and to our brain. Within the brain, the thalamus directs these pain signals to different areas for interpretation. The cortex catalogues the source of the pain and compares it to pain we've experienced before. The limbic system controls our emotional response to pain, making us cry or react in anger. Insects don't have these structures, suggesting they don't process physical stimuli emotionally.

Yes Mrs.B it is stupid but the Spanish Government wont ban it even though it is obviously cruel and hateful. But now the subsidy has stopped perhaps it will die a death of neglect. I do hope so.

Have always been against this stupidity.

This morning in the European Parliament, 438 out of 687 MEPs voted in favour of an amendment that would stop over €100 million in EU agricultural subsidies from being used to raise bulls for bullfights.
