TOPIC 12 | Biodiversity and Human Health Flashcards
refers to the variety of life and its processes, including the
variety of living organisms, the genetic differences among them, and
the communities and ecosystems in which they occur.
BIODIVERSITY
refers to diversity within a particular area, community
or ecosystem, and is measured by counting the number of taxa
within the ecosystem (usually species).
Alpha diversity
is species diversity between ecosystems; this involves
comparing the number of taxa that are unique to each of the
ecosystems.
Beta diversity
is a measurement of the overall diversity for
different ecosystems within a region.
Gamma diversity
Refers to the diversity of the gene pool of a given species, or diversity
at the DNA level.
Genetic Diversity
Not only based on the number of different species present in a
community, but also the relative abundance of each species and the
role they have in the community.
Species Diversity
Number of different species present in an
ecosystem.
Species richness
Relative abundance of individuals of each of
those species.
Species evenness
Refers to the variety of ecosystems within a given
region or landscape.
Ecosystem Diversity
are all of the non-living pieces of the ecosystem
that shape the environment.
ABIOTIC
include all living organisms within the ecosystem.
BIOTIC
the formation of new and distinct
species in the course of evolution.
Speciation
the process of a particular thing
ceasing to exist
Extinction
relates to the natural surroundings or conditions in which living
organisms exist.
Environment
is the dynamic, interdisciplinary study of the
interaction of living and non-living parts of the environment, with
special focus on the impact of humans on the environment. T
Environmental Science
is the systematic study of the inorganic world
PHYSICS
are the branches of science that deal with the study of
living organisms and their processes.
LIFE SCIENCES
When fossil fuels are burned, they release large amounts of carbon
dioxide, a greenhouse gas, into the air.
Global Warming
a U.S. federal law that aims to regulate air pollution
and protect the nation’s air quality.
Clean Air Act
It was originally passed in 1963 and has been amended several times.
Clean Air Act
Enacted in 1972, is designed to maintain and restore
the chemical, physical, and biological integrity of U.S. waters, including
rivers, lakes, and coastal areas.
Clean Water Act
s an international treaty within the United Nations
Framework Convention on Climate Change (UNFCCC) established in 2015.
Paris Agreement
is an annual event celebrated on April
22nd each year to raise awareness about
environmental issues
EARTH DAY
is the rapid spread of an infectious disease within a
specific population, geographic area, or community, often
exceeding what is typically expected.
EPIDEMIC
A disease outbreak is endemic when it is consistently present but limited to a particular region.
ENDEMIC
is an outbreak of a new infectious disease that occurs
on a global scale
PANDEMIC
are infections that are spread between people
and animals.
ZOONOTIC
is a mosquito-borne disease caused by a parasite.
MALARIA
form a subset of a larger class of weapons sometimes referred to as
unconventional weapons or weapons of mass destruction
