The White Throated Monkey, All You Need To Know

Hey buddies, today I want to write about this awesome creature that may face extinction soon if proper care is not taken, the white throated monkeys.

It would be heartbreaking waking up a day to hear that these creatures are no more in existence, I personally will drop tears. They are too cool to be missed.

The white throated monkey was initially hunted in large numbers for its special fur but the hunters never considered how the monkey reproduced to sustain its population. A female gives birth to just an offspring before death and this alone is a serious limiting factor.

They exist only in two African countries, Nigeria and Benin.
Their female gives birth to just an offspring.
They are frugivores
They leave on trees in damp areas
They can be found in large groups of up to 30 members, medium group of about 5 members. There males wander alone in most cases.
Their males grow bigger than females.
They are cute.

These animals are one of the reasons why we talk about environmental sustainability. We need to find a way to sustain them so that they don't go extinct.

Currently the forests where this animals live are preserved, they are Called holy-land. Neither hunting nor logging is allowed there but Still this is not enough, the issue of a female giving birth to just an offspring before death is a threat to their population and possible existence in the future world.

I suggest these animals should be studied properly  to ascertain if there could be anyway man can help make the females deliver more just an offspring before death.

Infiltration Definition, What Does Infiltration Mean?

Infiltration Definition will eventually answer the question What Does Infiltration Mean ? what factors affect infiltration ? This article will go in details to define and explain infiltration for clear understanding.


Definition of Infiltration is same as Infiltration Definition, the two phrases are interchangeable.

In a lay mans' therms, Infiltration Definition could be said to be the passage of liquid through a permeable medium in other to filter out its impurities. Here we will be talking about Infiltration Definition with general respect to environmental water cycle.

What does infiltration mean ?

Infiltration is the process by which water on the ground surface enters the soil through sand pores during precipitation. 

When precipitation occurs, before run off, water first infiltrates into the soil. When the soil have absorbed a reasonable amount of water, the infiltration rate becomes lesser and water starts to fill up on the surface of the soil. The filling up of water on the surface of the soil is what results to surface run off in the water cycle.


  • Water Flow Supply
  • Soil Type
  • Soil Coverage
  • Topography of Slopes
  • Soil Initial Conditions
I will like to explain in details how the above factors affect infiltration and why they do. I will take the points one after the other.

Water Flow Supply
This happens in the normal day to day rain we notice in our environment. When there is a sudden heavy down pour, there is little infiltration before runoff. This is because the water flow supply is very high. Also when there is a slow but steady down pour, you notice that a lot of water infiltrates into the soil before run off; that happens because the water flow supply is low.

Soil Type
The rate water infiltrates into the sandy soil is not the same rate it infiltrates into the clay soil. The sandy soil have relatively large pores compared to the clay soil which is more compact and closely packed in nature. Water infiltrates faster on loosely bound soil with large pores than it does on the closely bound soil.

Soil Coverage
Soil coverage affects infiltration, this is because before ever infiltration will take place, the water has to first of all pass through the soil covering material and this delays infiltration.
Vegetative covering affects infiltration in two ways, it delays quick infiltration but also fosters proper infiltration of water into the soil by preventing easy run off.

Topography of Slopes
The slope of an area affects how water infiltrates into the soil in such area. An area with steep slope experiences less infiltration before run off compared to an area with little or no sloping.

Soil Initial Conditions
The initial condition of soil affects infiltration. Dry soil tends to delay immediate infiltration while wet soil permits immediate infiltration if the soil is not yet saturated with water. This process can also be noticed on dry and wet cloths.

Evapotranspiration in water cycle is a word that houses two similar processes; evaporation and transpiration. Transpiration takes place on plants and causes the release of water vapor from plants while Evaporation takes place on water surfaces, soil, snow and some other wet materials.

Evapotranspiration in water cycle, describes the total water removed from an area by transpiration and evaporation. It is the sum of plant transpiration and evaporation from the earth's land and ocean surfaces to the atmosphere.

You can see the position of evaporation and transpiration in the hydrologic cycle.

Talking about evapotranspiration calculation is talking about how to calculate evapotranspiration in an area.
It is often estimated by subtracting the total outflow for an area from the total input of water. The change in storage must be included in the calculations, unless this change is negligible.

The potential Evapotranspiration rate from a well-watered root zone can approximate the rate of evaporation that can occur over a large free-water surface.
The available moisture in the root zone will limit the actual Evapotranspiration rate such that, as the root zone dries out, the Evapotranspiration rate decreases.

The rate of Evapotranspiration is also a function of soil type, plant type, wind speed and temperature. That is to say that it is affected by soil type, plant type, wind speed and temperature.
Strong winds cause an increase in Evapotranspiration rates. Plant types may also dramatically affect Evapotranspiration rates. E.g an oak tree may transpire as much as 160L/day, whereas a corn plant my transpire only about 1.9L/day.

Evapotranspiration Process

Weather parameters: Temperature, Humidity, wind speed, etc
Crop factors: Plant types
Management and environmental conditions: soil type, water availability etc
Evapotranspiration varies because of a multitude of factors some of which are listed above.
It is an important process in the water cycle because it is responsible for about 15℅ of the atmosphere's water vapor. Without that input of water vapor, clouds may never form and precipitation may never occur. Evapotranspiration may also directly affect soil moisture conditions.

The Hydrological Cycle Of The Environment

How much do you know about the Hydrological Cycle? Are you aware that it is the hydrological cycle that makes it possible for rain water that has dropped on the earth to be able to reverse back into the cloud and then goes again to return as rain fall?

The hydrological cycle just like the name implies, is a continues cyclic movement of water (hydro) between the Land , Sea and the Cloud (air).

There some core therms associated with hydrological cycle which help in explaining the process in details. The therms include;

  1. Precipitation
  2. Evaporation
  3. Transpiration
  4. Condensation
  5. Interception
  6. Infiltration
  7. Surface Runoff
  8. Water Table
Having taken note of these therms, I will like to explain them one after the other in details.

All water released from clouds such as rain, snow, hail, sleet & snow are all in this category. The therm precipitation, is the release of water from the clouds to the earth. Precipitation as part of the hydrological cycle, sends evaporated water down to earth.

Evaporation is the escape of water molecules from the surface of water or wet material to the cloud. Evaporation occur on the water surface at a low rate but is sped up when the water is being heated. Evaporation  as part of the hydrological cycle, sends Precipitated water back to the cloud.

This is the loss of moisture from plants and leaves to the atmosphere. You can take a look at EVAPOTRANSPIRATION, it explains Evaporation and transpiration in details.

This is When water vapour is cooled and it turns into water droplets to form clouds. condensation is brought about by reduction in the temperature of the water vapour which turns it into liquid, on further temperature reduction, the liquid turns into ice to form snow falls.

This is when trees or man made objects get in the way of rain reaching the ground surface. These material absolves part of the rain water.

Infiltration is the soaking of water into the soil. On a bare soil, water infiltrates the soil before surface run off. Infiltration rate varies depending on the type of soil involved. I will write on this in detail when I will write on "Soil Pore Sizes".

Water flowing across the surface of the land, whether in a channel (e.g drainage gutters) or over the land. Surface runoff can result to erosion when not properly channeled. It is indeed one of the major causes of erosion in some areas.

The level of saturated ground in the soil - it rises and falls depending on the amount of rain. At times you hear about a water logged area, this is when the water table has risen to a reasonable depth that the ground find it difficult to allow further infiltration. This leads to dirty water dumps on the surface of the earth.
