Conservation of Declining Populations

Conservation of Declining Populations

Conservation of declining population focuses on ways of detecting, diagnosing, and halting a population decline. The approach uses methods to prevent populations from going extinct.

Conservation of Small Populations

Conservation of Small Populations

Small population sizes put a species at extreme risk of extinction due to a lack of variation, and a consequent decrease in adaptability. This weakens the chances of survival under pressures such as climate change, competition from other species, or new diseases. Large populations are more likely to survive pressures such as these, as such populations are more likely to harbor individuals that have genetic variants that are adaptive under new stresses. Small populations are much less...

Habitat Fragmentation

Habitat Fragmentation

Habitat fragmentation describes the division of a more extensive, continuous habitat into smaller, discontinuous areas. Human activities such as land conversion, as well as slower geological processes leading to changes in the physical environment, are the two leading causes of habitat fragmentation. The fragmentation process typically follows the same steps: perforation, dissection, fragmentation, shrinkage, and attrition.

Distribution and Dispersion

Distribution and Dispersion

To understand intra-specific interactions in populations, scientists measure the spatial arrangement of species individuals. This geographic arrangement is known as the species distribution or dispersion. Highly territorial species exhibit a uniform distribution pattern, in which individuals are spaced at relatively equal distances from one another. Species that are highly tied to particular resources, such as food or shelter, tend to concentrate around those resources, and thus exhibit a...

Distributions to Estimate Population Parameter

Distributions to Estimate Population Parameter

The accurate values of population parameters such as population proportion, population mean, and population standard deviation (or variance) are usually unknown. These are fixed values that can only be estimated from the data collected from the samples. The estimates of each of these parameters are sample proportion, the sample mean, and sample standard deviation (or variance). To obtain the values of these sample statistics, data are required that have particular distribution and central...

What is Conservation Biology?

What is Conservation Biology?

Conservation biology is a scientific field that focuses on the preservation of biodiversity in order to protect ecosystems while meeting the needs of the human population. Humans require properly functioning ecosystems to maintain our supply of natural resources, including food, medicines, and building materials.

Area of Science:

Primate conservation biology
Wildlife ecology
African mammalogy

Background:

De Brazza's monkeys (Cercopithecus neglectus) in Kenya are critically endangered.
Habitat fragmentation due to expanding farmland isolates populations.
Limited protection is afforded by existing conservation areas.

Purpose of the Study:

To estimate the population size, distribution, and conservation status of De Brazza's monkeys in Kenya.
To identify key threats facing the species.
To inform urgent conservation strategies.

Main Methods:

Field surveys conducted from May to September 1983.
Population estimation and distribution mapping.
Assessment of habitat status and anthropogenic pressures.

Main Results:

The majority of De Brazza's monkeys inhabit small, isolated forest fragments.
Key threats include habitat loss, reproductive isolation, and human-wildlife conflict (persecution as pests/food).
Only a small fraction of the population is protected within Saiwa National Park.

Conclusions:

The De Brazza's monkey population in Kenya faces a high risk of extinction without immediate conservation interventions.
Habitat protection and mitigation of human-wildlife conflict are crucial.
Urgent conservation efforts are needed to prevent species loss in Kenya.
