Mammalian Reproductive Systems/ Phylogenetic &
Ontogenetic Development : An 8 page paper discussing the
concept of ontogeny in relation to the human reproductive
system. Dispells the belief propagated in the ninetenth century
that the embryonic stages of development are an exact mirror of
the evolutionary history of an organism. Bibliography lists
seven sources. Mammal.wps

Temperature Regulation in Animals : A 5 page review of
thermoregulation in animals. Discusses the differences between
ectothermia and endothermia in reptiles, fish, mammals and
birds. Discusses animals classified as poikilothermic, having a
body temperature which fluctuates widely, and those classified
as homeothermic, having a narrowly constricted body
temperature range. Includes a representative graph of these
variations and a graphic showing bones structure and its
relevance. Bibliography lists 5 sources. TempReg.wps

Bat Echolocation: The Perception of Distance and Depth
Through the use of Sonar: This 4 page paper provides an
overview of the basic elements of bat echolocation as an process
that is separate from the auditory and visual receptive
capabilities of other mammals. This paper considers the
prevalent biological structures and other components of bat
physiology that determine the capacity for echolocation, also
known as sonar. Bibliography lists 4 sources. MHbateco.wps

Brood Parasitism Among the Common Cuckoo (Cuculus
canorus): Genetic or Behavioral? : A 14 page literature
review of brood parasitism among the common cuckoo
(Cuculus canorus). Explores the concept of whether genetic
makeup determines host preference or if this phenomena is
really a result of the mature bird seeking out habitat in which it
was raised and consequently encountering more nests of a
specific species in that habitat than would be present in others
(i.e. natal philopatry). Includes a one-page Roman numeral
outline. Bibliography lists 8 sources. PPcuckoB.wps

The Human Digestive System / Its Phylogenetic and
Ontogenetic Development : A 7 page exploration of the
concepts of phylogeny and ontongeny in relation to the digesive
system. Discusses the embryonic development of the digestive
system and points out that, although it is possible that certain
phases of our evolution are reflected in our embryonic
development, this reflection is sporadic and quite different from
the view held in the nineteenth century that an organism's
embryological developmental phases give a clear picture of its
evolutionary history. Bibliography lists five sources.

Motor Executions And The Role Of The Central Nervous
System : A 7 page overview of the role of the central nervous
system in motor functions. Specific information is provided
about such components of the central nervous system as the
cerebral cortex, basal ganglia, and neurons. Bibliography lists
10 sources. Cerebraln.wps

The Role Of Mossy Fibers In Memory : A 7 page paper
outlining the role of mossy fibers in information transmittal and
in memory. Provides specific information about ultrastructural
changes which can occur as a result of stress or of exposure to
chemicals. Bibliography lists 15 sources. Mossyf.wps

The Process Of Osmosis : A 6 page overview of osmosis in
the living organism and in industrial applications such as
desalination, sewage treatment, and groundwater treatment. The
term osmosis is used to denote the process by which liquids
move through a semipermeable membrane. Bibliography lists
five sources. Osmosis.wps

Human Growth Hormones, Creatine Monohydrate, &
Steroids : A 10 page examination of steroids, nutritional
supplements and other means used by athletes to enhance
physical prowess. Bibliography lists fifteen sources.
Creatini.wps

Social Biology Of Wolves : A 25 page research paper on
wolves, their social biology, etc; The writer discusses various
types of wolves, how they travel in packs, survive as predators,
and so froth. Canis Lupis (Common wolf), gray wolves, and red
wolves are among the many types discussed. The writer is also
concerned with the evolutionary biology of wolves and other
relevant issues. Bibliography lists 9 sources. Wolves.wps
