Phylogeny refers to the study of evolutionary history among groups of organisms or individuals. The phylogenetic tree is a diagram that illustrates the relationships among species; this diagram is based on similarities and differences in the physical or genetic characteristics of different organisms. This diagram shows that all organisms originate from a single ancestor but have diverged due to speciation over a long period of time. (JP)

Speciation is an evolutionary process where populations become distinct from each other over a long period of time and develop into a new species. (JP)

Taxonomy deals with naming and classifying organisms. A taxonomic group of any rank, such as a species, family, or class is a taxa. ~S.Z.

The mutation rate of biomolecules is calculated and used narrow down the time in prehistory when two or more organisms diverged. (SZ)

Taxa refers to taxonomical groups like species, family, or class. Taxa are used in classifying organisms based on relatedness of characteristics.

Annotation needed

The classic allopatric model is also known as geographic speciation or the dumbbell model. Classic allopatric model is a kind of speciation that occurs when biological populations of the same species become isolated from each other. This isolation is what will prevent genetic exchange between the separated populations. ~S.Z.

Concordant means to agree. A variation of this word would be "concor", which has the same meaning. For this paper, the word may be used to describe how data collected seem to show the same variation or consistency. ~J.D.A.

Tenable is defined as something that can be "holdable". It could mean that something must have enough support for it to be upheld. In other words, if someone has an argument against an idea, the explanation should be enough to defend the concept. ~J.D.A.

Staggered suggests that the occurrence or arrangement of events did not happen at the same time. Staggered isolation is the thought of organisms become genetically isolated at different events or moments in time, therefore leading to speciation of these organisms. (DV)

Parsimony analysis deals with simplicity. In regards to science, there will be various explanations to certain phenomenon. According to parsimony analysis, the simplest explanation is the best one. ~J.D.A.

Conspecific is also like heterospecific as it pertains to classifying species. In the sentence it seems to be an opposing word to heterospecific. If heterospecific means organisms of differ species, then conspecfics must mean the opposite--must mean organisms of same species. ~J.D.A.

Heterospecific is used to classify organisms. "Hetero" means differ, and "specific" pertains to a particular subject/concept. Heterospecific means organisms that aren't the same species. ~J.D.A.

Isthmus is a stretch of narrow land that connects two large landmasses and separates two bodies of water.

The Isthmus of Panama formed 3 million years ago connecting North America and South America, while separating the Pacific Ocean and the Caribbean. (DV)

The snapping shrimp (Alpheus) is a species of shrimp well known for their asymmetrical claws which when closed produce a loud snapping noise. They borrow in the sand and attack their prey by quickly reaching out with their larger claw to capture it. (DV)

Within an ecosystem, there are external factors which may threaten the balance. Effects on stream ecosystems are heavily influenced by nutrients. Phosphorus, nitrogen, and carbon balance is essential to keep the ecosystem consistent. When carbon is released from the streams, it does not easily re-enter and goes into different forms. An excess of nutrients and the lack of standards for these ecosystems may be detrimental. Why is it important to conduct such research? Why is it important to care for and monitor other ecosystems?

Effects of Nutrients on Stream Ecosystems

This is organic carbon that can be dissolved in water and run through a filter; it is smaller compared to particulate organic carbon.

These forests shed annually and litter the streams, giving them an organic carbon source.

Co-limitation is the limiting of growth caused by two factors, both must be present in a set ratio to have an effect.

There is further visualization in figure 2, where the co-limitation of nitrogen and phosphorus are presented.

Sequestration is the collection and storage of carbon dioxide.

In this case, the carbon is being removed from the water and depletes the riverine food webs.

The system that clears waste from the brain.

Small molecular weight tracers are small, and can therefore diffuse easily.

The tracer used here, FITC, is only 30% smaller than the protein the scientists later examine, beta amyloid.

FITC's ability to diffuse and penetrate into the interstitial space should, therefore, be similar to beta amyloid, making this a powerful experiment.

The tracer will travel through the brain just as beta amyloid would.

This measure demonstrates a relationship between two variables. (JP)

The molecular clock is a hypothesis that states that DNA and protein sequences evolve at the same rate over time across different organisms. The molecular clock uses the mutation rate of biomolecules to estimate the time in prehistory when two or more life forms diverge.

"in vivo" is Latin for "within the living."

Here, it indicates that the experiment was done in a living mouse.

It has always been challenging to perform experiments on living animals; there are many technological, practical, and ethical concerns which generally limit the precision with which experiments can be conducted.

For example, in order to see beyond the surface of mouse's brain, we have always needed to cut the brain into thin sections, and therefore need to euthanize the mouse.

With the invention of two-photon imaging, it became possible to image noninvasively (without the need to euthanize) deep into a mouse's brain, unlocking powerful experiments such as those performed in this paper.

This is the convective exchange described in the abstract.

Convective exchange of cerebrospinal fluid (CSF) with interstitial fluid (ISF) is the basic mechanism by which the glymphatic system clears metabolites from the interstitial fluid.

ISF enters the brain along arteries, and flows into the interstitial space, replenishing CSF.

CSF flows into interstitial vessels along veins, carrying waste metabolites and proteins with it.

These two processes create net flows of CSF — in essence, small rivers of CSF flow, beginning with an ISF-to-CSF exchange near arteries, and ending with a CSF to ISF exchange near veins.

The combination of these rivers and the exchanges are called convective exchange.

Peripheral tissue refers to the entire body outside of the brain.

The body has the highly specialized lymphatic system for transporting interstitial metabolites (waste) and proteins to the liver.

The brain uses a different mechanism, recently discovered and dubbed the "glymphatic system." The glymphatic system is basically a cleaning system for the brain.

Additional proteins involved in neurodegenerative diseases.

Beta amyloid (Aβ) is a small protein involved in Alzheimer's disease (AD).

Large clumps of Aβ protein (called plaques) are very prevalent in Alzheimer's disease, and are thus the focus of an enormous amount of research.

It remains unclear what, if any, the causal connection is between Aβ and Alzheimer's disease, but clinical trials are under way to attempt to treat Alzheimer's disease by directly targeting Aβ plaques.

Neurodegenerative disease refers to several different diseases that impact the brain. Examples of neurodegenerative diseases include:

• Parkinson’s
• Alzheimer’s
• Huntington’s disease.

In all neurodegenerative diseases, there is a progressive degeneration and/or death of brain cells.

Beta amyloid (Aβ) is a small protein involved in Alzheimer's disease (AD).

Interstitial fluid (ISF) is the fluid responsible for carrying waste and proteins out of the CSF (cerebrospinal fluid) and away from the brain.

ISF flows in vessels surrounding arteries and veins, transporting waste away from the interstitial space (space between individual brain cells) for degradation.

ISF is continually exchanged for CSF near arteries and then replenished by CSF removal near veins, establishing a flow throughout the brain.

Cerebrospinal fluid, or CSF, is the fluid which circulates through the brain and spine.

It is the extracellular solution (fluid) surrounding all neurons in the central nervous system (brain and spine), so its composition must be carefully controlled to maintain proper function of neurons and brain cells.

Convective exchange of cerebrospinal fluid (CSF) with interstitial fluid (ISF) is the basic mechanism by which the glymphatic system clears metabolites from the interstitial fluid.

ISF enters the brain along arteries, and flows into the interstitial space, replenishing CSF.

CSF flows into interstitial vessels along veins, carrying waste metabolites and proteins with it.

These two processes create net flows of CSF — in essence, small rivers of CSF flow, beginning with an ISF-to-CSF exchange near arteries, and ending with a CSF to ISF exchange near veins.

The combination of these rivers and the exchanges are called convective exchange.

Interstitial space in this paper refers to the space surrounding cells in the brain, and the space between the brain and the thin layers (meninges) which surround it.

Damaged proteins and metabolic waste may be secreted into the cerebrospinal fluid (CSF), where they accumulate in the interstitial space.

These waste products are meant to be cleared, or removed, by fluid exchange through the glymphatic system.

A larger interstitial space would be expected to clear waste products faster, since there would be less resistance to diffusion and fluid motion.

Diffusion is the random movement of particles, which, on average, causes high-density pockets of particles to spread out into areas of lower density.

The final concentration of the particles after diffusion depends on the size of the container in which they diffuse: Cut an onion in a small kitchen and the fumes may be felt by everyone, but cut it in a sports arena and nobody will notice as the odor diffuses harmlessly.

In this paper, the authors inject small amounts of a substance, tetramethylammonium (TMA), into the interstitial space.

By measuring the concentration of TMA after diffusion, they can estimate the volume of the space in which the TMA is diffusing.

Metabolic processes like the production and use of energy, protein creation, and degradation, etc., all involve the generation of by-products, some of which can be harmful.

Metabolic homeostasis refers to the active process of maintaining proper, nonharmful levels of molecules produced during cell metabolism.

Disorders caused by a single gene.
