Glossary
O
Ornithologist

A term regularly used by non-birders to describe people who are involved in bird related activities, and which implies a professional involvement. The use normally makes birders cringe, and very few birdwatchers describe themselves with this term, although a scientist (see below) could probably correctly use this term.

Overexploitation

Overexploitation, also called overharvesting, refers to harvesting a renewable resource to the point of diminishing returns. Sustained overexploitation can lead to the destruction of the resource. The term applies to natural resources such as: wild medicinal plants, grazing pastures, fish stocks, forests and water aquifers.
 
In ecology, overexploitation describes one of the five main activities threatening global biodiversity. Ecologists use the term to describe populations that are harvested at a rate that is unsustainable, given their natural rates of mortality and capacities for reproduction. This can result in extinction at the population level and even extinction of whole species. In conservation biology the term is usually used in the context of human economic activity that involves the taking of biological resources, or organisms, in larger numbers than their populations can withstand. The term is also used and defined somewhat differently in fisheries, hydrology and natural resource management.
 
Overexploitation can lead to resource destruction, including extinctions. However it is also possible for overexploitation to be sustainable, as discussed below in the section on fisheries. In the context of fishing, the term overfishing can be used instead of overexploitation, as can overgrazing in stock management, overlogging in forest management, overdrafting in aquifer management, and endangered species in species monitoring. Overexploitation is not an activity limited to humans. Introduced predators and herbivores, for example, can overexploit native flora and fauna.

Ovulation

in mammals, the formation and discharge of a mature egg from the ovary

Opposable Thumb

a thumb which can be turned so that the fingertip can make contact with the fingertip of each of the other digits on the same hand; allows for thumb to come together with other fingers in a grasping action

Olfactory

relating to smell

Old World Monkeys

monkeys living in Asia or Africa

Ovulation

in mammals, the formation and discharge of a mature egg from the ovary

Overmarking

scent-marking over the scent-mark of others of the same species

Ovarian Cycle

the normal cycle of reproductive function and development in the female ovary, which includes development of an ovarian follicle (cell aggregation which contains the egg), rupture of the follicle, discharge of the egg, and formation and regression of a corpus luteum (yellow tissue formed in the ovary after the release of the egg)

Opportunistic

also: opportunistically referring to an organism with the ability to exploit newly available habitats or resources
