.my first step to success.

A most pleasant day to you fellow readers! I'm inexperience about blogging so I'm starting it on describing the things that are important not only to me but also to my mother land, the Philippines.
Anyways, I'd like to tell you guys first the reason why I'm into blogging. Aside from extra income, it's because on my frustration on my latter days. I can't express my thoughts. I'm not able to join the school newspaper club. I don't have the guts. But the day of enlightenment came! My friend introduced blogging to me. And so here I am! Blogging!
Thinking my first blog was the worst! It's like an entrance exam before you can take college. You'll experience the things you're experiencing when you're being introduced to your girlfriend's terrorist-like father(to all fathers, peace! This is just my opinion!:p). But through the support of my colleagues, I passed the ultimate test.
Please support my blog. I chose this ideas 'cause I'm a nature lover. I'm worried about the side-effects of the technology we're enjoying. The cars and coolants were destroying the ozone little by little. The power plants, especially those nuclear operated ones, spit radioactive materials that are dangerous not only to
living but also to our Mother Earth. Even non-living things will die, though they don't have life:p. So guys, do you still believe that technology will make life more easier or will it make more threats to all.
May God be with us all the time we make decisions. Please make a sign for us to know that were choosing the right thing. Please conserve the Mother Earth! Support the Earth Hour. For only 1 hour at exactly 8:30 pm(Philippine time). Please don't use electricity during Earth Hour. Thanks in advance!

more about tarsiers

Tarsiers are prosimian primates of the genus Tarsius, a monotypic genus in the family Tarsiidae, which is itself the lone extant family within the infraorder Tarsiiformes. Although the group was once more widespread, all the species living today are found in the islands of Southeast Asia.
Tarsiers are prosimian primates of the genus Tarsius, a monotypic genus in the family Tarsiidae, which is itself the lone extant family within the infraorder Tarsiiformes. Although the group was once more widespread, all the species living today are found in the islands of Southeast Asia.
The phylogenetic position of extant tarsiers within the order Primates has been debated for much of the past century, and tarsiers have alternately been classified with strepsirrhine primates in the suborder Prosimii, or as the sister group to the simians (=Anthropoidea) in the infraorder Haplorrhini. Analysis of SINE insertions, a type of macromutation to the DNA, is argued to offer very persuasive evidence for the monophyly of Haplorrhini, where other lines of evidence, such as DNA sequence data, remain ambiguous. Thus, some systematists argue that the debate is conclusively settled in favor of a monophyletic Haplorrhini.

At a lower level, it has been indicated that the tarsiers, currently all placed in the genus Tarsius, actually should be placed in two (a Sulawesi and a Philippine-Western group) or three separate genera (a Sulawesi, Philippine and Western group). Species level taxonomy is complex, with morphology often being of limited use compared to vocalizations. Several "vocal morphs" may represent undescribed taxa, taxonomically separable from T. tarsier (=spectrum) (such as Minahasa and a tarsier from the Togian Islands), and many others from Sulawesi and surrounding islands (Shekelle & Leksono 2004). This may also be the case for a number of poorly known isolated Philippine populations (such as the Basilan, Leyte and Dinagat populations of the T. syrichta group. Further confusion exists over the validity of certain names. Among others, the widely used T. dianae has been shown to be a junior synonym of T. dentatus, and comparably T. spectrum is now considered a junior synonym of T. tarsier. Notably, T. tarsier which has been argued to be a senior synonym of the widely used T. spectrum.
Tarsiers are small animals with enormous eyes; each eyeball is approximately 16 mm in diameter and is as large as their entire brain. Tarsiers also have very long hind limbs. In fact, their feet have extremely elongated tarsus bones, from which the animals get their name. The head and body range from 10 to 15 cm in length, but the hind limbs are about twice this long (including the feet), and they also have a slender tail from 20 to 25 cm long. Their fingers are also elongated, with the third finger being about the same length as the upper arm. Most of the digits have nails, but the second and third toes of the hind feet bear claws instead, which are used for grooming. Tarsiers have very soft, velvety fur, which is generally buff, beige, or ochre in color.
All tarsier species are nocturnal in their habits, but like many nocturnal organisms some individuals may show more or less activity during the daytime. Unlike many nocturnal animals, however, tarsiers lack a light-reflecting area (tapetum lucidum) of the eye. They also have a fovea, which is atypical for nocturnal animals.

The tarsier's brain is different from other primates in terms of the arrangement of the connections between the two eyes and the lateral geniculate nucleus, which is the main region of the thalamus that receives visual information. The sequence of cellular layers receiving information from the ipsilateral (same side of the head) and contralateral (opposite side of the head) eyes in the lateral geniculate nucleus distinguishes tarsiers from lemurs, lorises, and monkeys, which are all similar in this respect . Some neuroscientists suggested that "this apparent difference distinguishes tarsiers from all other primates, reinforcing the view that they arose in an early, independent line of primate evolution".
They are primarily insectivorous, and catch insects by jumping at them. They are also known to prey on small vertebrates, such as birds, snakes, lizards, and bats. As they jump from tree to tree, tarsiers can catch even birds in motion.

Gestation takes about six months, and tarsiers give birth to single offspring. Young tarsiers are born furred, and with open eyes, and are able to climb within a day of birth. They reach sexual maturity by the end of their second year. Sociality and mating system varies, with tarsiers from Sulawesi living in small family groups, while Philippine and Western tarsiers are reported to sleep and forage alone.
arsiers have never formed successful breeding colonies in captivity, and when caged, tarsiers have been known to injure and even kill themselves because of the stress.

One site having some success at restoring tarsier populations is in the Philippine Island of Bohol. The Philippine Tarsier Foundation has developed a large semi-wild enclosure that uses lights to attract the nocturnal insects that make up the tarsier's diet.

The 2008 described Siau Island Tarsier is regarded as critically endangered and was listed among the 25 most threatened primates by Conservation International and the IUCN/SCC Primate Specialist Group in 2008.

tarsiers to be isolated from people!(Philippines)

An international wildlife foundation has lauded Bohol lawmakers for its landmark legislation banning the viewing of tarsiers outside of their natural habitats.

The praises from the Born Free Foundation, an international wildlife charity group based in the United Kingdom, came even as local businessmen who had been displaying tarsiers for tourist viewing lobbied for the scrapping of the provincial ordinance.

Despite the ordinance's passage by the provincial board last February 3, Bohol Governor Erico Aumentado had not signed the measure as of Thursday.

The Born Free Foundation thanked the Bohol provincial board for introducing the ordinance, which they called ;forward thinking; and a ;compassionate decision.;

The letter from BFF senior scientific researcher Chris Draper was received by Board Members Alfonso Damalerio II and Esther Corazon Galbreath.

;The Philippines can be justifiably proud of this legislation, and it is our hope that other regions and countries may look to your example when considering similar legislation,; Draper said.

The foundation is working throughout the world to stop individual wild animal suffering and to protect threatened species in the wild.

In a visit to Bohol last January, a television crew of the British Broadcasting Corporation (BBC) featured the tarsiers in one of its documentary that will be shown all over the world.

The BBC crew, headed by celebrated British TV presenter and author Simon Reeve highlighted the need for rescue and care of the endangered species that are caged and displayed outside its natural habitat.

The provincial ordinance was adopted after calls to rescue the vulnerable tarsiers from its misery in tiny cages and give them lifetime care at spacious sanctuaries such as the 8-hectare sanctuary of the Philippine Tarsier Foundation in Corella town.

However, Damalerio also expressed disappointment over moves of some business establishments to block the implementation of the new ordinance.

;Instead of cooperating to return the tarsiers to the wild, most of the businesses engaged in the display of tarsiers are lobbying for the scrapping of the law,; said Damalerio who is the principal author of the ordinance.
