Mammal Characteristics
These structures, present in all mammals, produce milk that provides nourishment to developing young.
What are mammary glands?
This was the primary evolutionary importance of the amniotic egg.
What is dependence from water for reproduction?
This term describes the feeding habits of early mammals.
What is insectivorous?
This term describes where a taxon occupies a specific geographic range and occurs nowhere else.
What is endemic?
This term refers to an abnormality in organs or tissues due to trauma or disease.
What is a lesion?
Mammal erythrocytes are both biconcave and _______.
What is enucleate?
Mammals evolved from this amniote lineage that was characterized by a single temporal opening.
What is Synapsida?
Mammals most likely remained small and nocturnal throughout much of the Mesozoic because of competition with this group of vertebrates?
What are dinosaurs?
This faunal region is the largest and has the fewest number of endemic families.
What is the Palearctic?
Rabies is characterized by two basic forms, aggressive and ________.
What is Paralytic?
These two bones are involved in the jaw articulation of all mammals.
What are the dentary and squamosal?
Most of the major adaptive changes from non-mammal to mammal occurred in this synapsid lineage?
What is Cynodontia?
Breakup of this large land mass likely contributed to the extensive radiation of mammals.
What is Pangaea?
This avenue of faunal exchange offers little impediment to dispersal resulting in considerable faunal exchange.
What is a corridor?
The CDC found that 70% of cases of this disease were associated with peridomestic activities.
What is Hantavirus Pulmonary Syndrome?
The quadrate bone in synapsids was modified into this bone in modern mammals.
What is the incus?
The adaptive changes from amniotes to mammals were generally related to greater efficiency in this and this.
What are feeding and locomotion?
Reduced optic lobes in the brain, enhanced hearing and vibrissae suggest that early mammals exhibited this circadian pattern of activity?
What is nocturnality?
This term describes the fragmentation of a taxon’s distribution by some external factor.
What is vicariance?
This carnivore species is the primary reservoir of rabies in the Atlantic Coast states, including Georgia.
What is the Northern Raccoon?
This structure functions to increase the volume of the thoracic cavity in mammals facilitating movement of air into the lungs.
What is the diaphragm?
The first mammals appeared in this geologic period.
What was the Triassic?
The major radiation of mammals occurred in this geologic era.
What is the Cenozoic?
This term describes the observed phenomenon of decreased species richness from the equator to the poles?
What is a Latitudinal Diversity Gradient?
This disease is caused by the bacterium Yersina pestis.
