either detached from land and freely floating, or has been blocked by
land-attached ice while drifting past.
- Not unpleasant to the taste.
- A branch of science dealing with pollen and spores.
- 1. Argentinean steppe
grasslands; 2. grassland created by burning and cattle occupation.
- An area on the Brazil-Bolivia-Paraguay frontier that covers more than 100,000 sq km
(38,000 sq mi) and is best characterized by its low degree of land relief and annual
flooding; swampy savanna.
- 1) Alpine meadow of northern and western South American uplands. 2)
- An organism. that lives in or on another organism (the host), from which
it obtains food, shelter, or other requirement. A parasite usually
does not kill its host organism.
- Referring to a female who has produced offspring.
- The process of giving birth.
- A social organization based on livestock raising as the primary economic activity.
- Pectoral fins
- The pair of fins that are located one on each side of a fish or cetacean just behind the gills.
- The hairy covering of a mammal.
- Referring to a plant that continues to live for several years.
- A permanently frozen layer in the soil in frigid climates, found in
alpine, arctic, and antarctic regions.
- A (logarithmic) scale ranging from 0 to 14, which is used to
determine how acidic or basic a substance is. Pure water has a pH of 7. Substances with a pH
less than 7 are acids and substances with a pH greater than 7 are bases.
- Referring to an animal that has a tendency to return to or stay in its home area, or to
return yearly to the same area to breed.
- A method of observing hard-to-see animals by taking their pictures automatically, using
remote cameras triggered when the animal interrupts an infrared light beam.
- Referring to the closeness of evolutionary descent.
- The study of the functioning of living organisms and of the functioning of
their constituent tissues or cells.
- A member of the order Pinnepedia: seals and
- An internal organ providing nourishment to and removing waste products from the blood of
an unborn young. The unborn young's blood is conveyed to the placenta via the umbilical
- A body of water's animal ("zooplankton") and plant ("phytoplankton")
life, usually microscopic to small in size, that floats or swims weakly.
- Plant exudate
- A substance that has oozed out of a plant at the site of insect or other damage.
For example, gum that has oozed out of a tree through a wound in the bark.
- Relating to an animal that walks on the sole of its feet with the heel touching the
ground; as opposed to digitigrade.
- The Pleistocene Epoch began approximately 1.8 million years ago and ended about 11,000
- A process of soil formation, especially in humid regions and often under coniferous or
mixed forest , involving principally leaching of the upper layers with accumulation of
material in lower layers and development of a group of soils (the soils are called
"podzols") that have an organic mat and a thin organic-mineral layer above a
gray leached layer resting on a dark alluvial horizon enriched with amorphous clay.
- A mass of microspores in a seed plant appearing
usually as a fine dust (in flowering plants, formed in the anthers
that produce the male cells).
- Pollen grain
- One of the granular microspores that occur in pollen and give rise to the male gametophyte
of a seed plant.
- Polyandry; Polyandrous
- Referring to a mating system where a female can mate with several males during one
breeding season, but a male mates with only one female (compare monogamy,
polygamy and polygyny).
- Referring to a female that has two or more estrus
cycles in one breeding season.
- Polygamy; Polygamous
- Referring to a mating system where males and females each can have more than one mate per breeding
season (compare monogamy, polyandry
- Polygyny; Polygynous
- Referring to a mating system where a male can mate with several females during one
breeding season, but a female mates with only one male (compare monogamy,
polyandry and polygamy).
- Polymorphic gene
- A gene at which the most common allele has a frequency
of occurrence of less than 0.95.
- Referring to an animal that feeds on many kinds of food.
- A group of animals of the same species that occupies a particular area; usually refers
to a group that is somewhat separate from other groups of the same species.
- Abbreviation for "parts per thousand."
- Refers to young mammals which are born with their eyes and ears open and
are able to stand and walk, regulate their body temperature, and excrete
without assistance. The young of grazing animals (e.g. cattle, sheep, and
horses) are precocial. (Compare "altricial".)
- The action of a predator in killing and eating its prey.
- An animal that eats other animals.
- Capable of, or adapted for, grasping.
- An animal that is hunted or caught for food by another animal (the "predator").
- A long, flexible nose or trunk.
- Referring to a mating system where a member of one sex mates with more than one member
of the other sex, and each relationship is ephemeral and terminates after mating without a
social bond being formed.
- Scientists refer to lemurs (includes sifakas), lorises, galagos, pottos, and tarsiers as "prosimians"
to distinguish them from monkeys, apes and humans. "Prosimian"
means "pre-ape", that is, primates that appear in the fossil
record before monkeys, apes and humans. They more closely resemble primitive
primates that lived millions or tens of millions of years ago than do other
living primates. Generally, prosimians look and act much differently than
monkeys and apes. For example, lemurs tend to have longer fox-like, wet
noses, compared to monkeys which have flatter faces and dry noses. One could
guess from this difference that smell plays a greater role in prosimian
behavior than it does in that of monkeys, who tend to be more visually
oriented. (Duke Univ. 2003)
- One-celled organisms that are present in almost every kind of habitat.
Some of them are disease-causing parasites of humans
and domestic animals.
- The period in life when an animal becomes sexually mature and is then
physically capable of reproducing sexually.
