Final Exam Vocabulary Flashcards
Voltinism
The number of broods or generations of an organism in a year. The term is most often applied to insects
Palynology
The analysis of grains of pollen
Haplotype
A unique sequence of a gene (like an allele, but at the DNA sequence level)
Ecology
The study of how organisms interact with
the environment’s biotic and abiotic factors
Population
A group of individuals of the same
species that live in the same area at the same time
Community
A group of species that interact
with one another in a particular area
Ecosystem
Consists of all the organisms in a
particular region along with non-living
components (biotic and abiotic factors)
Evolution of Increased Competitive Ability
Hypothesis (EICA)
Predicts that plants introduced to an environment that
lacks their usual herbivores (or disease agents) will
experience natural selection favouring individuals that
allocate less energy to defense and more energy to
growth and reproduction.
Acclimatization Societies
Voluntary associations in the 19th and 20th centuries that encouraged the introduction of non-native species in various places around the world with the hope of
their acclimatization and adaptation.
These societies were started during a period
of colonialism when Europeans began to take over
unfamiliar environments, and the movement sought to
establish familiar plants and animals (mainly from
Europe) in new areas while also bringing exotic and
useful foreign plants and animals into the European
colonies.
Biodiversity (Scientific Definition)
The variability among all living organisms
and the ecological systems of which they are a
part; this includes variation at the genetic, species,
and ecosystem levels
Biodiversity (Cultural Definition)
The dimensions of nature that we cherish and wish to conserve, where in individual species have been categorized as more or less desirable in particular places.
Invasive Species Framework Phase 1
Transport

Low OR High Impact
Order of Invasive Species Framework
Transport, Establishment, Spread, Impact (TESI)
Example of an ecological impact of an invasive species
As [pacific] lionfish populations grow, they put additional stress on coral reefs. Lionfish eat herbivores, and herbivores eat algae from coral reefs. Without herbivores, algal growth goes unchecked, which can be detrimental to the health of coral reefs.
Example of an evolutionary impact of an invasive species
Hybridization between red deer and non native sika deer in various eastern European countries which might cause reduced fitness and disruption of local adaptation
Example of a positive impact of an invasive species
Zebra mussel filtering water in Lake Ontario; zebra mussels have contributed to a decrease in algae to the point where you can see much deeper into the water
Example of an invasive species control method
Acoustic trap that emits mating and aggressive calls of male gobies that attract both male and female round goby to the trap; controls round goby populations while causing minimal harm to native fish species
