Deciduous trees are those which shed their leaves once a year at the time of winter season and later grow new leaves, plants those keep their foliage throughout the year are called evergreens. Deciduous trees usually have broad leaves e.g., ash, beech, birch, maple and oak. There is a confusion exists over the dominance of trees in rain forest, but most of ...

I am just summarizing ddiez's answer with a small addition. Robustness is the ability of the system to maintain its steady state or at the very least qualitative nature of the steady state with minor changes in the parameters of the system. This is different from stability which actually means the ability of the system to return to its steady state when ...

I think robustness and plasticity are different concepts, although related to each other. I would define plasticity as the property of a system to adapt to external changes. As defined in the wikipedia page for phenotypic plasticity: Phenotypic plasticity is the ability of an organism to change its phenotype in response to changes in the environment. ...

Quoting verbatim from this site. The reference is not really a scientific article but you can check the references it cites. Some were not in English so I did not check. However these points are fairly logical Nitrates are the preferred nitrogen source: Non-volatile: unlike ammonium, nitrate is non-volatile, so there is no need to ...

Plants have sulfate transporters which they use to assimilate sulfur. Since sulfate is the conjugate base of sulfuric acid, this could be construed as a "yes" for your question. Sulfuric acid would be present in its conjugate base form at physiological pH values. However, it would be unwise to water your plants with sulfuric acid, as many plants have an ...

You are right but a small correction: P represents primary producers. So the answer is just dead plants or tissues such as broken branches. Death, excretion because of turnover (which includes urine or other metabolites), tissue turnover (shedding of dead cells, molting etc) Maintenance, locomotion, repair, immunity

It is certainly possible to use general relationships to predict this. The relationship between population density/abundance and body size is an old topic in ecology, that fall within the field of allometrics (how different features of organisms scale with body size). Your assuption that there is generally a negative relationship is correct, and the ...

There are a lot of approaches to this kind of problem. Starting with the simplest approach I think you'd benefit from using a K-means classification, with K=2 (or higher numbers to address @Luigi's concerns about model bias.) Once you've defined the geometric center of each population, you can treat them as foci, and use the equidistant points between each ...

There are a number of things to clarify here; Fecundity is the number of offspring that is produced by an individual, and this can be separated into potential fecundity (maximum reproductive capacity) and realized fecundity (number of offspring actually produced). Realized fecundity is very similar to fertility, which is defined as the number of viable ...
