In Spain, which holds about 50 % of the European population suggested causes of decline include poisoning by accumulation of lead, pesticides ( especially due to large-scale use in the control of Schistocerca gregaria locust swarms ), and electrocution.

There are many causes for this change.

A number of causes are believed to be involved, including habitat destruction and modification, over-exploitation, pollution, introduced species, climate change, endocrine-disrupting pollutants, destruction of the ozone layer ( ultraviolet radiation has shown to be especially damaging to the skin, eyes, and eggs of amphibians ), and diseases like chytridiomycosis.

This causes the iron crystals to deform intrinsically when the crystal structure tries to change to its low temperature state, inducing great hardness.

This abnormal electron density affects the applied magnetic field and causes the observed chemical shift to change.

The torque caused by the two opposing forces F < sub > g </ sub > and-F < sub > g </ sub > causes a change in the angular momentum L in the direction of that torque ( since torque is the time derivative of angular momentum ).

The wind over the open end of a vertical tube causes little change in pressure on the other side of the manometer.

Detection of climate change and attribution of causes, in Houghton, JT et al ..

In the last hundred years, the face value of circulation coins has usually been higher than the gross value of the metal used in making them ; exceptions occurring when inflation causes the metal value to surpass the face value, causing the minting authority to change the composition and the old coins to begin to disappear from circulation ( see Gresham's Law.

A third significant change, outside North America, has been the shrinking of the minority " fellowships " due to defection to the main group and natural causes.

The domino effect is a chain reaction that occurs when a small change causes a similar change nearby, which then will cause another similar change, and so on in linear sequence.

This effect, known as precession, causes the coordinates of stationary celestial objects to change continuously, if rather slowly.

In Aristotle's Metaphysics, there are four causes of existence or change in nature: the material cause, the formal cause, the efficient cause, and the final cause.

According to Maxwell's equations, a spatially varying electric field causes the magnetic field to change over time.

Yahweh causes Pharaoh to change his mind about allowing the Israelites to depart ; he pursues them, but God destroys the Egyptian army at the crossing of the Red Sea ( Yam Suf ) and the Israelites celebrate Yahweh's victory.

This comes about by analogy with " January " ( which ends in "- uary " but not "- ruary "); as well as by a dissimilation effect whereby having two " r " s close to each other causes one to change for ease of pronunciation.

Donald Hebb proposed that incoming information causes a series of neurons to create a neurological memory trace in the brain which would result in change in the morphological and / or chemical changes in the brain and would fade with time.

Repeated firing causes a structural change in the synapses.

In Christianity, faith causes change as it seeks a greater understanding of God.

This proportional change causes the drain-to-source current to remain relatively fixed independent of changes to the drain-to-source voltage and quite unlike the linear mode operation.

He has, however, argued that political efforts to reduce the causes of climate change distract from other global problems that should take priority:

Fick's second law predicts how diffusion causes the concentration to change with time:

When a ligand binds to the GPCR it causes a conformational change in the GPCR, which allows it to act as a guanine nucleotide exchange factor ( GEF ).

Hemoglobin can bind protons and carbon dioxide, which causes a conformational change in the protein and facilitates the release of oxygen.

An " attribute " consists of a foreground and a background colour, a brightness level ( normal or bright ) and a flashing " flag " which, when set, causes the two colours to swap at regular intervals.

Variation in natural skin colour is mainly due to genetics, although the evolutionary causes are not completely certain.

A wavelength of 656. 3 nm is in the red part of the spectrum, which causes the chromosphere to have its characteristic reddish colour.

Normally, the indicator causes the colour of the solution to change depending on the pH.

His vanity causes him to throw hysterical fits when Sophie disturbs his bathroom potions, causing his hair to go the wrong colour, or when she accidentailly ruins his clothes.

Cloning of a foreign DNA fragment into the YAC causes insertional inactivation, restoring the red colour.

A very rare British vagrant in 1982 was of this type, leading to speculation that whatever mutation causes the colour variation also affects the navigational abilities of this thrush.

Dennett asserts that if she already truly knew " everything about colour ", that knowledge would necessarily include a deep understanding of why and how human neurology causes us to sense the " qualia " of color.

Grossly, steatosis causes organ enlargement and lightening in colour.

* Buried ditches will hold more water and buried walls will hold less water than undisturbed ground, this phenomenon, amongst others, causes crops to grow better or worse, taller or shorter, over each kind of ground and therefore define buried features which are apparent as tonal or colour differences.

The use of 老外 refer exclusively to Westerners causes some animosity among some of them who feel that they are referred to as " foreigners " on the basis on their skin colour and not on the basis of nationality.

If the red absorbance is less than the green, then as the thickness t increases, so does the ratio of red to green transmitted light, which causes the apparent hue of the colour to switch from green to red.

This was Two Essays ... with some observations on the causes of the differences of colour and form between the white and negro races of men.

These include coloured keys which open doors of the same colour, giving access to other areas of the game ; an ' ice crystal ' which, whilst carried, causes water in its vicinity to freeze, enabling access to previously inaccessible areas ; trampolines which can be jumped on to reach high areas ordinarily out of reach, and many others.

Grabbing a crystal ball causes Kage's clothes to change to the next level in colour and thereby attain certain powers ( bigger shuriken and / or faster speed ); if Kage is hit while in green or orange clothes, he does not die but revert to his normal red clothes.

However, long aging in oak barrels softens the taste and causes the development of more complex flavours and a brown colour.

The reason for this is the nenano interval ; for it seems to be in some way halved, even if we are not aware of it ; in other words, we perform the nenano intervals weakly in upward direction, in order to give the characteristic colour of nenano, but in downward direction perform them correctly, and this causes the melody to get out of tune.

The Choanephora cucurbitarum causes a stem and leaf rot of Withania somnifera Oxyrachis tarandus ( a treehopper / cowbug species ) feeds on the apical portions of the stem, making them rough and woody in appearance and brown in colour.
