Reproducibility is one of the foundations of science. If something is true, it should be true every time. While it’s exciting to create new studies with new results, it is equally important to recreate studies done by others.
It may come as a surprise to many that science never proves something to be true. We can falsify a hypothesis, but there is always a chance that our positive results are due to chance. Reproducing studies is one way to reduce that possibility.

To a gardener choosing which plants to grow, pH is an important consideration. While the pH of most soils falls somewhere between 3 and 9, the majority of common landscape plants prefer a pH slightly on the acidic side, say 6.2 to 6.8. However, some plants, such as blueberries and rhododendrons, prefer an even more acidic soil (with a pH in the 5 to 6 range) and other plants, green ash trees and clematis, for example, do best under more alkaline conditions, with a pH above 7.

Here in Colorado, when it’s hot out on the plains, we head to the mountains. And there’s no better mountain to head to than Mt. Evans. No hiking required, unless you want to reach the 14,265 foot peak, and even that is only a quarter mile up a series of switchbacks from the summit parking lot.

If you were stymied on Monday, now can you name this bird? The photo was taken in Colorado in May. The answer will appear in Monday’s post.
August should be a time of bounty. By now, seeds sown last spring should have had time to grow and produce a harvest—leafy red chard, crunch lettuce, glossy eggplant.

This bird was photographed in Colorado in May. Can you name it? I will post the uncropped photo on Saturday, giving you one more chance to identify the bird. The answer will appear at the end of next Monday’s post.
Bellflower, Campanula sp.
Campanulaceae is a family of plants with members ranging from the towering palm-lobelias of Africa to cottage garden flowers with names from a child’s book of fairytales: Canterbury bells, Cup and Saucer Vine, Harebells, and Fairy’s Thimbles. Two familiar genera, Campanula and Lobelia, are members of this family.
