Density00:56

Density

20.8K
Density is an important characteristic of substances, crucial in determining whether an object sinks or floats in a fluid. Its SI unit is kg/m3, and its cgs unit is g/cm3. The density of an object helps in identifying its composition, and also reveals information about the phase of the matter and its substructure. The densities of liquids and solids are roughly comparable, consistent with the fact that their atoms are in close contact. However, gases have much lower densities than liquids and...

Conservation of Small Populations

17.6K
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...

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.

Ecological Niches

27.3K
All organisms have a position within an ecosystem. The complete set of living and nonliving factors—including food resources, climate, and terrain—that define the position of a given organism are collectively referred to as the organism’s ecological niche.

Habitat Fragmentation02:31

Habitat Fragmentation

21.8K
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.

Current Density01:21

Current Density

5.6K
The total amount of current flowing through one unit value of a cross-sectional area is referred to as current density. If the current flow is uniform, the amount of current flowing through a conductor is the same at all points along the conductor, even if the conductor area varies. The current density consists of the local magnitude and direction of the charge flow, which varies from point to point. Current density is measured in amperes per meter square, and direction is defined as the net...

Area of Science:

  • Ecology
  • Wildlife Conservation
  • Mammalogy

Background:

  • Ocelots (Leopardus pardalis) are considered abundant wild cats, crucial for small-felid population dynamics.
  • Limited ecological data exists for ocelots, especially within the Amazon basin.

Purpose of the Study:

  • To estimate ocelot density in Amanã Reserve, Central Amazonia, Brazil.
  • To provide the first density estimate for ocelots in the Brazilian Amazon.

Main Methods:

  • Conducted three camera-trap surveys over consecutive dry seasons.
  • Utilized a spatial capture-recapture (SCR) model with shared detection parameters.
  • Achieved 7020 camera-trap days, yielding 93 independent ocelot records.

Main Results:

  • Estimated ocelot density at 24.84 ± 6.27 individuals per 100 km².
  • This density is lower than other Amazonian sites and predicted values.

Conclusions:

  • The Brazilian Amazon's ocelot density may be lower than previously assumed.
  • Highlights the need for refined survey methods, especially with low recapture rates.
  • Emphasizes the Brazilian Amazon's importance as a species stronghold.
