In temperate regions of the northern hemisphere where cold temperatures are expected seasonally and are usually for long periods of time, the main strategy is freeze avoidance. In temperate regions of the southern hemisphere, where seasonal cold temperatures are not as extreme or long lasting, freeze tolerance is more common. [2]
Distribution of most nematode species is correlated negatively with elevation (due to temperature and precipitation) and salinity, and positively with soil moisture, soil organic matter, and nutrient availability. [3] Eudorylaimus spp. is the second most abundant nematode, followed by Plectus murrayi who are the least abundant nematodes. [3]
Because of the cold weather it is hard for plants to grow. Frozen ground covers most of the polar regions for the majority of the year. Permafrost reaches a thickness of 600–1,000 m (2,000–3,300 ft) deep. Large amounts of permafrost can lead to poor water drainage. Due to the permafrost the water in the soil remains frozen for most of the year.
The pre-flight warm-up behavior of a moth. Insect thermoregulation is the process whereby insects maintain body temperatures within certain boundaries.Insects have traditionally been considered as poikilotherms (animals in which body temperature is variable and dependent on ambient temperature) as opposed to being homeothermic (animals that maintain a stable internal body temperature ...
Photograph taken 21 March 2010 in Norwich, Vermont. Frost heaving (or a frost heave) is an upwards swelling of soil during freezing conditions caused by an increasing presence of ice as it grows towards the surface, upwards from the depth in the soil where freezing temperatures have penetrated into the soil (the freezing front or freezing boundary).
Fire ants sting and bite, particularly little kids since they can come into contact with dirt mounds playing outside. During those rare summer showers, fire ants will immediately turn up.
Remember these three things to get rid of ants: Exclude, sanitize and apply pesticides. 1. Exclude: Caulking or sealing openings that could allow ants inside can prevent invasion. It might also ...
At least six major areas of cryobiology can be identified: 1) study of cold-adaptation of microorganisms, plants (cold hardiness), and animals, both invertebrates and vertebrates (including hibernation), 2) cryopreservation of cells, tissues, gametes, and embryos of animal and human origin for (medical) purposes of long-term storage by cooling to temperatures below the freezing point of water.
