Until the advent of freeze-tolerant solar collectors, they were not considered suitable for cold climates since, in the event of the collector being damaged by a freeze, pressurized water lines will force water to gush from the freeze-damaged collector until the problem is noticed and rectified.

Many ice rinks consist of, or are found on, open bodies of water such as lakes, ponds, canals, and sometimes rivers ; these can only be used in the winter in climates where the surface would freeze thickly enough to support human weight.

Rinks can also be made in cold climates by enclosing a level area of ground, filling it with water, and letting it freeze.

Chapter XI deals with evidence from biogeography, starting with the observation that differences in flora and fauna from separate regions cannot be explained by environmental differences alone ; South America, Africa, and Australia all have regions with similar climates at similar latitudes, but those regions have very different plants and animals.

This can be seen by the success of seed plants ( both gymnosperms and angiosperms ) in dominating biological niches on land, from forests to grasslands both in hot and cold climates.

The buds of many woody plants, especially in temperate or cold climates, are protected by a covering of modified leaves called scales which tightly enclose the more delicate parts of the bud.

Especially in warm climates, plants secrete waxes as a way to control evaporation and hydration.

Most tropical rainforest plants are considered to be evergreens, replacing their leaves gradually throughout the year as the leaves age and fall, whereas species growing in seasonally arid climates may be either evergreen or deciduous.

In cool temperate climates, fewer plants are evergreen, with a predominance of conifers, as few evergreen broadleaf plants can tolerate severe cold below about-30 ° C.

Because they are descended from tropical plants and tend to require warm temperatures throughout a relatively long growing period, cantaloupes grown in temperate climates are frequently started indoors for 14 days or longer before being transplanted outdoors.

Natural historians began to draw connections between climates and the animals and plants adapted to them.

Many plants grown in temperate climates require vernalization and must experience a period of low winter temperature to initiate or accelerate the flowering process.

This is not necessarily a severe loss in tropical climates where plants bloom all year but in more temperate climates it can leave the colony with insufficient stores to survive the winter.

Chardonnay grapes usually have little trouble developing sugar content, even in cooler climates, which translates into high potential alcohol levels and limits the need for chaptalization.

It will need regular watering, but not as much attention as is needed in other climates.

Coast redwoods are classified as temperate rain forests and they need wet and mild climates to survive.

Backpackers may need skis or snowshoes to traverse deep snow, or crampons and an ice axe to cross ice in colder climates.

Animals in cold climates need to conserve as much energy as possible.

Due to the aseptic technology, there was no longer a need for a cold chain, which made the package economical and suitable for warmer climates, something that greatly expanded potential markets.

In hot climates, compared with wooden buildings, adobe buildings offer significant advantages due to their greater thermal mass, but they are known to be particularly susceptible to earthquake damage.

In colder climates, extra construction costs can be as little as 15 % more than new, conventional buildings.

The Lake Chad Basin embraces a great range of tropical climates from north to south, although most of these climates tend to be dry.

They can also be planted under a cloche or germinated indoors in cooler climates, then planted out later.

In temperate or polar climates the dry season is due to the inability of the plant to absorb water available by to be in the form of ice.

His nursemaid offered to take him to warmer climates abroad at his father's expense in the hope that this condition would not be so badly affected.

Another problem with knives that have metal handles is that, since metal is an excellent heat-conductor, these knives can be very uncomfortable, and even painful or dangerous, when handled without gloves or other protective handwear in ( very ) cold climates.

The ability of carp to survive and adapt to many climates and water conditions allowed the domesticated species to be propagated to many new locations, including Japan.

Their expected useful life is only as long as the wire they are composed of and if used in severe climates ( such as shore-side in a salt water environment ) must be made of appropriate corrosion-resistant wire.

But afternoons in the rainy season can be hot and humid, a feature of tropical climates.

Good quality oregano may be strong enough almost to numb the tongue, but the cultivars adapted to colder climates often have a lesser flavor.

In temperate climates, cut roses are often grown in glasshouses, and in warmer countries they may also be grown under cover in order to ensure that the flowers are not damaged by weather and that pests and disease control can be carried out effectively.

São Tomé and Príncipe's army is a tiny force with almost no resources at its disposal and would be wholly ineffective operating unilaterally ; infantry equipment is considered simple to operate and maintain but may require refurbishment or replacement after 25 years in tropical climates ; poor pay, working conditions, and alleged nepotism in the promotion of officers have been problems in the past, as reflected in the 1995 and 2003 coups ; these issues are being addressed with foreign assistance aimed at improving the army and its focus on realistic security concerns ; command is exercised from the president, through the Minister of Defense, to the Chief of the Armed Forces staff ( 2005 )
