2022-10-22 18:43:51 What is Gloger’s rule explanation?

Colour variation associated with Gloger’s rule is mainly due to differences in melanin pigmentation.

Melanins, the most common pigment in birds and mammals, come in two main types:
eumelanins, responsible for black and various shades of grey,
and
pheo-melanins, yielding brown, buff and rufous colours.

Mixtures of both produce intermediate shades.

Climatic variables correlate in different ways with the deposition of both melanin types. In dry and warm areas only deposition of eumelanins is reduced, while in very cold areas both types of melanins are diminished but the effect on pheomelanin is more marked. This results in pale coloration at higher latitudes where temperatures are low, darker and more intense colours in humid and warm places and pale reddish coloration in warm areas with low rainfall.

Camouflage, photoprotection, protection against parasites and pleiotropic effects have been suggested as four main causes of the rule.

The viscous ink of a ballpoint pen is made of a paste containing about 25-40 percent dye that is suspended in oil. Thanks to this formula, developed and improved by all “fathers” of ballpoint pens, ink doesn’t leak or clog. It is one of important elements of commercial success of this type of writing instruments.

Before an average ballpoint pen runs out of ink, it can write 45,000 words.

The world's biggest ballpoint pen was designed by Acharya Makunuri Srinivasa from India in 2011. The pen weighs 37 kilograms and is 5.5 meters high. This pen is fully functional and holds the Guinness world record.

The world’s smallest pen is the 'Nanofountain Probe’ . Scientists normally use it for nanoscale on-chip patterning. The lines produced by this device are only 40 nanometers wide. It carries its own ink reservoir.
