If I was a monkey...

Postby Eddie » Sun Dec 20, 2009 2:44 am

If I was a monkey, I wouldn't want to be from the Arctic.
Most monkeys live in the forests of the tropics and subtropics, where warm temperatures ensure a year-round supply of food. In rain forests, where food is abundant, monkeys often stay in the same area all year, but in drier habitats, they have to range further a field.

Although most monkeys live in warm climates, some do survive in extreme environments. The Japanese macaque manages to survive the winter cold on the Japanese island of Honshū-the only nonhuman primate to survive that far north. A few tropical monkeys survive on high mountains well above the snow line, some at elevations.
So you see, it makes no sense that these 'Monkeys' are from the 'Arctic'
BUT, if I was a sea monkey...
The Effect of Water Temperature on Sea Monkey Growth
The objective of this project was to see which temperature of water would make sea monkeys grow the
biggest. The hypothesis was that the 80 degree water would be the most effective on the sea monkey's
Materials- Three 5 gallon fish tanks, two water heaters, Microscope slide, water, wire, tape, permanent
marker, 3 packages of sea monkey refill, 9 jars of the same size that are bigger than 4 oz, measuring cups,
and teaspoon measurers
Methods: One tank was heated to 80 degrees, another tank was heated to 70 degrees, and the last tank was
left at room temperature (60 degrees). Three jars with four ounces of water were placed in each tank. Then
4/25 of a teaspoon of water purifier was added to all the jars. After 24 hours 4/25 of a teaspoon of sea
monkey eggs was added to every jar. After 7 days three sea monkeys out of each jar were taken out and
put on a small drop of water on a microscope slide. They were then measured with a ruler in millimeters,
and put back in jars. The measurements were recorded in a data graph.
The results from this experiment were that the 80 degree water was the best temperature for the growth of
the sea monkeys. The average sea monkey size of the 80 degree water was 5.2 mm. The average sea
monkey size of the 70 degree water was 2.2 mm, and the average sea monkey size of the 60 degree water
was .9 mm.
In this experiment the data collected supported my hypothesis that the 80 degree water would be the best
for the growth of sea monkeys. The project was very accurate because the whole experiment was in an
aquarium environment, and the water was kept at a consistent temperature. These results help people that
use sea monkeys or brine shrimp as food for other animals. It also helps anyone who just wants sea
monkeys as pets.

Or maybe they should have a look at this:
Temperature in the Monkey: Transmitter Factors Released from the Brain during Thermoregulation

When perfusate is collected from the anterior hypothalamus of a cooled donor monkey and is transfused to a corresponding hypothalamic site in a normal monkey, fever occurs in this recipient. Conversely, perfusate from a heated donor monkey lowers the recipient monkey's temperature when the same hypothalamic transfusion procedure is followed. These experiments provide direct evidence of a neurochemical "coding" within the specific anatomical region of the brain historically implicated in the control of body temperature.

Diencephalic efflux of calcium ions in the monkey during exercise, thermal stress and feeding

1. The diencephalon of the unanaesthetized macaque monkey was radio-labelled with calcium by a microinjection of 6-8 μC 45Ca2+ into the third cerebral ventricle through a permanently implanted cannula. Successive 5 min push—pull perfusions of the mid-line hypothalamic region with an artificial C.S.F. were carried out at a rate of 28 μl./min every 20 min. A washout curve of declining 45Ca2+ radioactivity was thus generated.
2. When the monkey exercised strenuously on a special `rowing machine' to obtain highly palatable banana pellets, its body temperature rose sharply. As the monkey exercised, during a sequence of push—pull perfusions, the concurrent efflux of 45Ca2+ ions increased markedly in the corresponding samples of diencephalic perfusate. This enhanced activity of calcium ions continued throughout a 30 min work period and persisted as long as the monkey's temperature was elevated in the interval immediately following exercise.
3. Exposure of the monkey's trunk, between neck and thigh to cold air of 5 °C likewise augmented the amount of 45Ca2+ ions in the diencephalic push—pull perfusates; however, a similar exposure to air warmed to 35 °C failed to alter the pattern of 45Ca2+ efflux from the animal's diencephalon. If a fasted monkey consumed only the banana pellets but was not exercised, the level of 45Ca2+ in the perfusate also increased transiently, just at the onset of feeding.
4. We conclude that a local change in calcium transport, binding or other cellular activity of the cation within the diencephalon could play an important role in the central mechanism underlying the set-point rise in a primate's temperature which accompanies vigorous exercise. Further, the results support the idea that this cation functions in the diencephalic control of metabolic heat production as well as in the overall processes of energy metabolism, particularly in relation to feeding.

African leaf-eating monkeys are 'likely to be wiped out' by climate change
December 18, 2009 African leaf-eating monkeys are 'likely to be wiped out' by climate change


Colobus monkeys are one of the primate species most at risk from climate change.

(PhysOrg.com) -- Monkey species will become 'increasingly at risk of extinction' because of global warming, according to new research published this week.

The research reveals that populations of monkeys and apes in Africa that depend largely on a diet of leaves may be wiped out by a rise in annual temperatures of 2°C. The study by researchers from Bournemouth, Roehampton and Oxford Universities suggests that the species most at risk are the already endangered gorillas and colobine monkeys.

The paper, published online in Animal Behaviour, pinpoints which species are most threatened by climate change in a series of new global maps. The maps show current and predicted distributions of primates, comparing the populations according to their diet and the amount of enforced rest they are predicted to need.

The researchers warn that Old World monkey populations in Africa will be hardest hit even by a very modest 2°C increase in global mean temperature, especially those whose diets are mainly leaf-based such as the beautiful colobine monkeys.

In contrast, New World monkeys in South America will be virtually unaffected by a rise of 2°C in mean temperatures.

However, even the South American species will begin to suffer if temperatures rise as much as 4°C because suitable habitats will then become increasingly fragmented, and small fragmented populations are more liable to risks of extinction.

These predictions are based on analyses of ecological constraints that determine how much time animals are forced to rest. The researchers found that animals that have forced rest have less time to forage for food or engage in other biologically essential activities, such as forming friendships.

Although most primates have adaptations that help them cope with the heat, they head for shelter and rest when the sun gets too hot. The researchers show that resting time is influenced by three main factors: the percentage of leaves in the animals’ diet, temperature variation and mean annual temperature. When these three effects come together, susceptible species will be unable to cope and populations will go extinct.

The researchers used climate models coupled with an analysis of quantitative data on the behaviour, diet and group size of different primate species across the world.

African monkeys and apes that have a high percentage of leaves in their diet are geographically more restricted even now, being confined to a relatively narrow region around the equator. However, fruit-eating species like the baboons and guenon monkeys of Africa typically have a much wider latitudinal range and can cope with a wider range of climatic conditions.

This ecological separation between fruit- and leaf-eating species is much less obvious in the Americas, and so these species will be much less badly affected by climate warming.

The contrast between the continents may be due to the fact that African fruit-eating species may have developed a particular ecological adaptation to more challenging habitats than those encountered by species in South America.

Lead author Dr Amanda Korstjens, from Bournemouth University, said: ‘The possibility that enforced resting time might have so strong an effect on where on the map a major mammal group is likely to survive has not previously been appreciated. This study suggests that the amount of time available for monkeys and apes to gather food and socialise may be a key factor when looking at possible effects of climate change on animal distribution patterns in the past and in the future.’

Professor Robin Dunbar, from the Institute of Cognitive and Evolutionary Anthropology at the University of Oxford, said: ‘We often worry about deforestation and hunting as the two main factors threatening the extinction of primate populations, but these results suggest that even if we find ways to solve these problems, it may not save some species of monkeys and apes from extinction. Instead, we perhaps should worry about ensuring that we provide these species with habitats that are more in tune with their capacities to cope with climate change.’

Dr Julia Lehmann, from Roehampton University, said: ‘At overall temperature increases of 2°C and 4°C, the distribution of habitat suitable for species that eat a lot of leaves will be greatly reduced. The distribution of suitable habitat would become progressively restricted and increasingly fragmented. The scale of the effect is sufficiently large that the implications for the survival of the dietetically more specialised primates are worrying.’

This could be just like the infinite monkey theorem.
