Glossary
Biogeography
The study of the geographical distribution of plants and
animals.
Congener
A member of the same taxonomic genus as another plant or
animal.
Source: Merriam-Webster
Dimorphism
The presence of one or more morphological differences
that divide a species into two groups. Many examples come
from sexual differences of particular traits, such as body
size (males are often larger than females), or plumage
(male birds are usually more colourful than females).
These result from sex-linkage of the genes coding for the
particular trait. However, some dimorphisms, such as the
colour-phases of some birds, may not be sex linked.

Genotype
The genetic constitution of an organism, as opposed to
its physical appearance (Phenotype). Usually this refers
to the specific allelic composition of a particular gene
or set of genes in each cell of an organism, but it may
also refer to the entire genome.

dictionary of zoology. Oxford University Press.
Inbreeding
Inbreeding is the production of offspring by individuals
related by descent. Inbreeding reduces reproduction and
survival (reproductive fitness) – this is referred to as
inbreeding depression… Inbreeding will increase the risk
of extinction for most species under a wide range of
circumstances.

Lactation
Lactation: noun, the secretion of milk by the mammary
glands, the suckling of young, origin mid 17th century:
from Latin lactates (n-), from lactare “suckle”, from lac,
lact – “milk”.

English. Ed. Judy Pearsall. Oxford University Press 1998.
Parturition
Parturition: noun, formal or technical: the action of
giving birth to young, from late Latin parturitio(n-),
from parturire “be in labour”.
Source: The New Oxford Dictionary of
English. Ed. Judy Pearsall. Oxford University Press 1998.
Polygyny / polygynous
In animals, a pattern of mating in which a male has more
than one female partner.
Source: Allaby, M. (Ed.) 1999. A
dictionary of zoology. Oxford University Press.
Phylogeny or phylogenesis
The development over time of a species, genus, or group,
as contrasted with the development of an
individual (ontogeny).
Site fidelity
The tendency of animals to remain largely faithful to the
habitat they are familiar with.
Stochastic factors/events
Stochastic factors are chance factors that come into play
in small populations. They differ from deterministic ones
in that they have large random components, with effects
varying in direction and magnitude by chance.
