Some animals migrate vast distances to avoid unfavourable situations; others reduce environmental stresses by modifying their behaviour and the habitats (immediate surroundings) that they occupy.
There is a lot of reining in to do — about 80 percent of all antibiotics sold in the United States are used in animals, the vast majority to promote rapid weight gain, not to treat sick animals.
Making meat also requires supplying animals with vast amounts of water and food: in the United States producing 1kg of live animal weight typically requires 10kg of feed for beef, 5kg for pork and 2.5kg for poultry.
And it is not just large, lumbering animals requiring vast tracts of uncultivated land.
Raising farm animals uses vast amounts of resources, including energy, three-quarters of the world's agricultural land, and one-third of our fresh water consumption.
In pqe-1 Htn-Q150 pqe-1 Htn-Q150 pqe-1 Htn-Q15090%) of animalsrons undergo cell deathein less than three days (Figure S2).
Despite the fact that there are multiple phenotypic differences between male and female animals, the vast majority of diet studies and gene expression analyses have been performed only on males, and direct comparisons of hippocampal transcriptome responses of males and females to environmental factors, such as dietary intake, are largely lacking.
After tamoxifen treatment of mT/mG RIPCreER animals, the vast majority of insulin+ cells co-expressed GFP, indicating that recombination is efficient in β-cells (Fig 1F and G).
The higher consensus levels on questions related to exposure compared with toxicokinetics and toxicology is not surprising since the dose, exposure route, animal model, vast number of endpoints, and methods for extrapolation to humans vary greatly.
Whenever we see exotic fauna or vast numbers of animals in a movie today, our first assumption is that it's "all been done with computers" – and it usually has, for better or worse.
