Hydrogen is a zero-carbon and energy dense alternative energy carrier with clean burning properties and biohydrogen production by microalgae can reduce production associated GHG emissions to a great extent.
In this way, a dense alternative resource can induce evolutionary suicide (sensu Dieckmann and Ferrière 2004) when a less dense alternative resource would be a weaker attractor and would allow the mutualism to persist.
While a dense alternative resource with a wide temporal distribution can make a mutualism more robust to climate change, a dense alternative resource with a narrow temporal distribution can make a mutualism less robust (Figs 3C,F and 4: lower right in each panel).
Second, the presence of a dense alternative resource with a wide temporal distribution can subsidize the focal pollinator population as it evolves, preventing the mutualism from crossing its Allee threshold.
On the other hand, data from RCTs, which provide the highest quality of evidence for examining the potentially causal effects of LCS intake on body weight, indicate that substituting LCSs for calorically dense alternatives results in a modest reduction of body weight, BMI, fat mass, and waist circumference.
For example, when we were looking for a source of brown rice as a more nutrient-dense alternative to white rice, we found a farmer, Greg Massa, who worked with us to find a way to grow this rice at scale, allowing us to access his high-quality product at an affordable cost.
For dietary intake, participants can choose to eat smaller portion sizes, consume a less energy-dense alternative or eat less of a certain food product.
Weekly paclitaxel proved a dose-dense alternative to the 3-weekly regimen, achieving at least similar activity in breast and lung cancer, and showing some advantages in terms of feasibility and decreased toxicity.
Snack on apples, carrots, and other healthy goodies in front of your folks as often as possible, and be sure to take extra helpings of veggies at dinner instead of more calorie-dense alternatives.
The second is a softer, denser, scruffier alternative worn as a mark of authority.
In the circumstances of food insecurity, it is possible that individuals rely more heavily on less nutritious, inexpensive, calorie-dense food alternatives, again highlighting the importance of affordable access to good-quality nutritious food.
