Arabidopsis thaliana (A. thaliana) is a commonly used plant for research because of ease of manipulation. With a genome of approximately 125 megabase pairs (Mbp) and only 5 chromosomes, it is relatively quick to sequence and much background literature exists on the genome. It also matures in 6 weeks, and is easily cultivated in confined spaces.

Individuals vary in the number of offspring they produce. Fecundity is often measured as the number of offspring produced by an individual. When populations have higher fecundity, there are more individuals to populate the region just outside the current species range, which result in increased spread velocity.

Species acquire new range at a given rate, expressed as land acquired per unit time. How fast species spread into new range is important for how quickly invasive species can take over an area or a native species can adapt to a changing climate.

The base-line economical worth assigned to plants for just being plants.This paper explains that there are many different characteristics that can be used to calculate a plant's economic worth based on the plant species importance to an ecosystem.The economical worth of plant species increases as levels of CO2 in the atmosphere increases because of their ability to take CO2 out of the atmosphere and store it.

Companies have to pay for the amount of carbon dioxide they emit, so in the context of this paper it means the dollar amount assigned to carbon.

Different species that conduct photosynthesis to create energy. Different plant species that convert light energy into chemical energy. For this experiment, the author questions the impact of increased species richness on carbon storage in American grasslands.

A rapid increase in the amount of a quantifiable unit. In plant species, proliferation refers to the rapid increase in the number of plant species that now inhabit earth. The diverse array of species around the world is a valuable component to producing ecosystem services that benefit all organisms.

Organisms that require oxygen to produce energy and to survive. Plants help to maintain the earth's oxygen rich atmosphere through photosynthesis (CO2 is taken in and oxygen is released). Without the existence of plant life, other organisms that depend on oxygen to breathe would not exist.

As plants conduct photosynthesis and gain energy, they grow. Plants accumulate biomass through the storage of carbon and uptake of other vital nutrients required for plant grow. By taking the dry-weight of plants, the scientist can see how much carbon is being taking up through the soil.

Marginal value is the amount of economic growth received for each additional unit of species richness relative to the previous unit. The paper suggests that marginal value decreases with the addition of species, when considering biomass accumulation, due to competition. This implies the addition of each new species to an ecosystem causes diminishing returns on rate of growth for all plants because each plant is competing for limited resources.

The amount of energy the grasslands will be producing. If there is a greater degree of competition between the different species than there will be a higher output of growth and carbon storage.

The number of different collective groups of organisms that are in a habitat. The increasing number of varieties of organisms will be compared to the carbon storage throughout the habitat. The scientists expect that a higher number of variety will disclose an increase in economic value.

A measure of the variety of life or different species in a specific environment. Increased biodiversity is associated with promoting competition which increases carbon storage.

The ability of plants to uptake carbon from the environment and convert it into biomass. Plants decrease CO2 levels by absorbing carbon from the atmosphere to use for photosynthesis.

DEET is a ubiquitous repellent known to effectively provide protection from many biting insects, particularly mosquitoes. Its exact interaction between itself and the organisms it targets are not yet fully known. Yet, what is understood is that it possesses two primary lines of negative feedback that act as a defense to prevent feeding. These two are the olfactory and gustatory levels. This, along with other smaller contributors are what give DEET its ability to deter insects

In statistics, the term robust or robustness refers to the strength of a statistical model, indicating that the model has good performance for data drawn from a wide range of probability distributions.

A power law is a functional relationship between two quantities, where one quantity varies as a power of the other.

An example of a power law is Zipf's Law, which says that the distribution of words in a given corpus of text is a function of the frequency of the words. In a given corpus of text, the most frequent word occurs twice as much as the second most frequent one, which shows up twice as much as the third most frequent one, and so on.

A stochastic event has a random probability distribution or pattern that may be analyzed statistically but may not be predicted precisely.

An aggregate shutdown is a stochastic event because it depends on the probability of that aggregate being found by predators (entities capable of shutting it down).

An aggregate is fragmented when it is broken down into other aggregates of smaller size. This happens, for instance, when an aggregate is shut down.

A bipartite graph is a set of graph vertices decomposed into two disjoint sets such that no two graph vertices within the same set are connected.

In the paper, the disjoint sets of nodes that constitute the bipartite graph are aggregates and followers. In this graph, there are no direct connections between aggregates (they can only be connected through other people). The same holds for followers: they are connected to aggregates, but not (directly) to other followers.

Reference: http://en.citizendium.org/wiki/Self-radicalization

An ad hoc group of followers of an online page that interact in a language-agnostic way and with freely chosen names that help attract followers without making public the identities of the group's members.

The paper uses the term aggreagates in three ways:

1. as a members of an ad hoc group of followers on an online page (as defined above);
2. as refering to pro-ISIS aggregates, which are aggregates that appear to express a strong allegiance to ISIS;
3. in contrast to followers, which are people who interact with aggregates online.

In the Supplementary Material, the authors provide a link to a video showing how agrregates can be set up for any purpose on Facebook, VKontakte, and other similar websites.

The term "ecology" can be defined as the set of relationships between a complex system and its surroundings or environment. In the context of this paper, the relationship between pro-ISIS ad hoc groups formed online constitutes an ecology. It can also be interpreted as "ecosystem" in this context.

The corpora allata (CA) is responsible for the production and release of juvenile hormones. The corpora cardiaca (CC) complexes are responsible for regulating reproduction and metamorphosis. The CC send out messages for the body to produce hormones that mature ovaries and hormones to produce insulin.

This involves an intracellular signaling pathway, which occurs within the cell membrane of a cell, and is important in regulating the cell cycle. Also, it is directly related to how cancer forms and the length of an organism's lifespan.

This type of insulin is also known as beef insulin because it is extracted from the pancreas of cattle. Bovine insulin differs from human insulin because it is less soluble and absorbed by the body more slowly. Like human insulin, bovine insulin regulates how much glucose is administered to muscle and fat cells.
