Populations
Rates of Immigration, Emigration, Births and THIS determine population sizes.
What are deaths? (aka mortality)
This is the name of an interaction between species in which both of them benefit.
What is a mutualism?
Plants, Algae, and phytoplankton are examples of these organisms which lie at the base of a food chain/web.
What are primary producers?
The long term change in atmospheric conditions including temperature is THIS.
What is climate?
In Tiverton, RI you can enjoy a bagel and boba drink at a cafe while helping to socialize these adoptable animals.
What are cats?
This is a tool used by ecologists and also insurance companies to predict life expectancy.
What is a Life Table?
This is an interaction where one species benefits but the other is not affected (like a cattle egret and cow, or bird nesting in a tree).
What is a commensalism?
Gross Primary Productivity- Heat- Respiration = THIS
What is Net Primary Productivity?
As glaciers melt in the arctic, THESE events have been increasing along the West Coast of the US due to shifts in the jet stream causing hotter, drier conditions.
What are wildfires?
Living organisms generally have a life-history trade-off between reproduction and THIS. IF they have a lot of babies then THIS tends to shorten.
What is longevity (life span)?
The number of individuals surviving at the beginning of an age interval (i.e. 1-2 years) divided by the initial number of individuals born.
What is the survivorship rate?
When a cuckoo bird ejects eggs of a warbler from the warbler's nest and the warbler continues feeding it, that is an example of THIS interaction (one of the forms of CONSUMPTION).
What is (brood) parasitism?
In a food chain a relatively a small percentage of THIS is transferred from one trophic level to the next, resulting in a pyramid structure.
What is biomass (or energy)?
Based on our measurements in ice cores, the value of this has not been as high as it is for at least the last 400,000 years.
What is CO2 concentration?
The education of these individuals is key to improving economic opportunity, which increases funds for health care, and thereby helps to control global human population growth.
What are Girls/ Women/ Females?
Turtles and plants have THIS type of survivorship curve where individuals are unlikely to make it to maturity, but if they do, then they live for a long time.
What is a Type III survivorship curve?
Predation, THIS, and parasitism are three types of CONSUMPTION.
What is Herbivory?
This is the reason blue fin tuna, kingfish mackerel or swordfish has high concentrations of mercury and should not be consumed by pregnant women and children.
What is biomagnification?
Shelled organisms in the ocean are affected by this phenomenon as CO2 concentrations rise because it increases solubility of carbonate.
What is ocean acidification?
This endangered species was taught migratory routes by a man in a small motorized glider.
What is the Whooping Crane?
In logistic population growth models, the growth rate (dN/dt) decreases as the number of individuals N approaches THIS.
What is K (Carrying Capacity)?
According to the competitive exclusion principle, what happens when two species have completely overlapping niches?
One of the species goes extinct or is out-competed by the other species.
Addition of THIS has been proposed as a controversial approach to increasing NPP in the ocean and thereby (hopefully) causing a drawdown of CO2 in the atmosphere.
What is iron fertilization?
This is a process by which rates of climate change are increased. For example, ice melts and less heat is reflected back to the atmosphere, which leads to warmer ocean waters and thus more ice melt.
What is a positive feedback?
THIS is the date and time of your final exam.
