<br />
The name Orangutans come form Malay meaning "person of the forest". These great apes used to roam the forests of South East Asia but are now only found within the forests of Borneo and Sumatra. Their populations have decreased to a quarter of what they once were a century ago. Threats to their survival on top of deforestation and the subsequent loss of habitat also include illegal pet trade where infants are targeted and to get to them, poachers kill their parents. Now the peat fires in Sumatra are threatening to encroach upon the forest home to the Orangutans.<br />
<br />
The Sumatran Orangutans are presently only found in North Sumatran. They are almost exclusively arboreal, meaning they rarely come down from the trees at all, and they are more dependent on the primary forest, being less tolerable of habitat disturbances compared to their Borneo cousins. However, even though the Borneo species are more tolerable, they cannot hold out against peat fires.<br />

As you can see from the pictures above, the hotspots in Borneo do indeed coincide with known Orangutan populations. Hopefully relief reaches these great apes fast enough for their forests to be saved.<br />

When most people talk about Singapore and crabs, the image of Singapore's signature Chili Crab dish comes to mind. Would it not be ironic for Singapore to have no crabs of our own. even with such a dish being one of the country's most famous dish? Luckly, we do not have 1, but 3 species of endemic crab that call Singapore home: the <i>Johora singaporensis</i>, the <i>Irmengardia johnsoni</i> and the <i>Parathelphusa reticulata</i><span style="font-family: Verdana, Geneva, sans-serif; font-size: xx-small;"><span style="background-color: white; line-height: 16.8px;"><i>.</i></span></span><br />

The Singapore freshwater crab, <i>Johora singaporensis</i>, has been making head line news this year as we struggle to find and maintain its population in the wild as habitat loss continues to poss a problem to the species. Staying in fast-flowing clean freshwater streams, these tiny crabs live out their lives, up until recently, out of the public eye. With 2 remaining known wild populations, scientist are struggling to help these crabs get back on their feet again. Not much is known about the ideal conditions, lifestyle and even the decline of the freshwater crabs and so scientist are in a mad rush trying gleam as much knowledge from these wild populations in order to start captive breeding programmes in order to boost populations numbers and prevent the species from going extinct.<br />

The Johnson's freshwater crab, <i>Irmengardia johnsoni,</i> is another tiny crab, faring only slightly better then its cousin. This crab has its home in the Bukit Timah Nature Reserve and the Central Catchment nature Resesrve. Facing habitat loss as well, it may well be wiped out as the new Cross Island Line intends to make its route under the reserve, threatening the streams this native crab inhabits by ground works.<br />

Lastly the Singapore Swamp Crab, <i>Parathelphusa reticulata</i>, is one of the most critically endangered animals, it inhabits a small area of 20 hectares in the Nee Soon Swamp Forest. This crab is not as small as its freshwater cousins, but the small locality it limits itself to is a problem that pose a threat to its entire population.<br />
<br />
Singapore's endemic crabs have only been discovered for around 40-50 years and yet they are already on the verge of extinction. If we want to continue to live along side these small marvels, Singaporeans in their own right, we are going to have to be more sensitive to the impacts we have on our own environment.<br />

One of the most famous, locally endangered animal, appearing on numerous logos, the most famous would be that of the Wildlife Reserve Singapore conservation fund (WRSCF) . Our very own armoured anteater, the Sunda Pangolin.<br />
<br />
The Sunda Pangolin (<em style="background-color: white; box-sizing: border-box; color: #333333; font-family: Lato, sans-serif; line-height: 26px;"><span style="font-size: x-small;">Manis javanica</span></em>), is also known as the Malayan Pangolin, is a native animal of Singapore. It is an nocturnal insectivore, preying on ants and termites. Their conical head, sticky tongue and toothless mouth are adaptations allowing the animal to efficiently extract ants and termites out of their nests. Their powerful front claws allows them to easily break apart nests and climb trees with the help of their tails. The signature scaly shell protects them not only from the ant bites, but from predators as well, when threaten the pangolin can curl up into a ball. The shell is made up keratin, the same material as your fingernails, but thicker, making it difficult to chew or break.<br />

</tbody></table>
Pangolins are highly threatened by poaching and are still hunted for their meat and for traditional chinese medicine, where their scales are believed to be cures for ailments such as asthma and eczema, big markets still exist in China, Vietnam and Thailand. Hunting these animals in large numbers due to their demand as well as habitat loss, where forests are cleared for things like agriculture, are driving the population numbers of the species down.<br />
<br />
Singapore has been investing much time and effort to save the local pangolins still present in our wild, most pangolin sightings do not happen on mainland, but on our offshore islands, such as Pulau Tekong. Some organizations helping to conserve and study them include the WRS, Save Pangolins and even the Singapore Night Safari, having successfully breed and raise 3 cubs in captivity. The WRS hosted in 2013, a convention to brainstorm on solutions to better conserve the pangolins. The brainchild of the conference, the Singapore Pangolin Working Group, was formed by the WRS and started in 2014. Other organisations like Save Pangolins conduct educational programmes in order to get the public more involved and informed about the situation, the conservation efforts and most importantly, what they can do to help stem the poaching of these unique beasts.<br />
<br />
These majestic animals have a fighting chance to be saved and with everyone putting in effort, I hope to see these shy creatures gain a strong foothold for survival here in Singapore.<br />

As to what inspired me to write on it, well, my class has been talking about how kids now a days spend more time indoors instead of out, so my next few posts will be more on the local wildlife here in Singapore. What better way to start these few posts with the adorable Eurasian Tree Sparrow.<br />
<br />
The Eurasian tree sparrow has been around in Singapore for a long time, so much so that very few actually realize that the small bird is actually an invasive species. Not to be confused with its cousin, the Eurasian House Sparrow, this little bird has certainly adapted well to human environments and is now a common sight to see throughout Singapore. Some might wonder why it is called a "tree" sparrow seeing as it often builds its nests in buildings and structures.this is because in Britain, the tree sparrow is known as a woodland bird, making its nests in trees. However in Singapore, we ended up with tree sparrows making their nests in houses instead, the government did a good job relocating everyone into flats (pun intended). The house sparrow though rare in Singapore, can be differentiated from the tree sparrow by size and the colour of its head. The tree sparrow is smaller in size and has a chestnut brown head, whereas the house sparrow has a grey-slated head.<br />
<br />

<div style="text-align: center;">
<span style="font-size: x-small;">Another way to differentiate the Eurasian Tree Sparrow (left) form the Eurasian House Sparrow (right) is the presence of a black ear covert on the white chin of the tree </span></div>
<div style="text-align: center;">
<br /></div>
To be a successful invasive species, it has to be able to out-compete local species as wells as other invasive species. As an invasive species, the tree sparrow seems to be losing its touch. As of late, bird watchers have seen a slight decline in the number of tree sparrows sighted and it has been suspected that this is due to the sparrows slowly losing ground to the more aggressive Javan Myna and the House Crow. All 3 birds being scavengers they are usually seen around Singapore's hawker centers eating scraps, they compete for a decreasing supply of food available as hawker cleaner practices become more efficient. Not only is their food supply under threat, the holes in which these birds, including the sparrow, usually nests in have been continually blocked or fenced up. The tree sparrow is still abundant in Singapore and many are hoping for a come back of the species, preferring them over the mynas and the crows. <br />

Everyone knows how plastic takes a very long time to decompose, one might hear stories of how turtles choke to death on floating plastic bags, or if you're slightly more well versed, you might even have heard of the infamous garbage patches in various oceans. For a long time, scientist have struggled to find ways to make plastic biodegradable, I find it slightly ironic when they discovered this solution to their problem, it was nature that once again provided it. Introducing the-plastic eating mealworms.<br />

</tbody></table>
Mealworms are the larvae of a species of darkling beetle, <i>Tenebrio molitor</i>, they are detritivores, assisting in the cleanup of dead organic matter. They are also important in the wild and feed a variety of other organisms such as various birds, spiders and rodents. It was first discovered that several types of bottom feeders are actually able to eat polystyrene - commonly known as Styrofoam. The mealworms in particular, possess several types of bacteria in their gut, capable of breaking down these plastic compounds into carbon dioxide and biomass, excreting most of it in their feces. The process of plastic digestion in this worm is so efficient that they are able to solely survive on eating polystyrene. The polystyrene the mealworms readily ate were not treated in anyway before they were presented. it was also noted that the plastic diet did not affect the larvae's life cycle in any significant way when compared to those that were fed grains.<br />

This is a huge step forward in solving the problem of solution. Not only have we found a way to degrade plastics, that are non-biodegradable, we now can dispose of them without emitting toxins into the air and further pollute the environment. This provides a sustainable solution, considering that majority of our products and waste contains high amounts of plastic. However, we have yet to explore the long term effects of this process, therefore, it is crucial that we continue to practise responsible waste management.<br />

Hello! Today I'll be talking about an interesting find that happened right here in the waters of Singapore! Drum roll~~ Introducing the Neptune's Cup Sponge! This sponge was thought to be extinct since 1908 where the 2 specimens of the sponge was collected in West Java. Subsequently, the sponge has been identified after being dredged up in 1990 giving people hope that a wild population might still exist somewhere. it is not until 2011 that a live specimen of the sponge was found in Singapore's waters.<br />
<br />
In the past, it is said that these sponges were extremely common is the waters round Singapore, so much so that they were a commonly used for a variety of purposes, such as bathtubs for children. Yes, they do grow pretty big!<br />

The 2 specimens were found around the waters of Sister island, one of Singapore's few protected areas for wildlife. The rediscovery of the species, with 2 specimens in relatively close proximity, gives researches hope that there is a healthy wild populations of the sponges that they have not found.Little is known about the sponge, with scientist still debating if it does indeed belong in the genus <i>Cliona</i>. As such, live specimens, of which the only known 2 are the ones mention above, are extremely valuable to researchers wishing to study the sponge and its various aspects.<br />
<br />
The rediscovery of the sponge, although a big news, was not highlighted upon much upon its initial discovery, perhaps it is best to keep it that way. This is as Singapore still has poaching activities present in its water. It would be a logical line of thought, that keeping the location of the sponges vague and not highlighting its presence to possible poaches, is part of a plan to protect the species. After all, Neptune's Cup Sponge is known to be sought after by collectors because of its unique shape and it is said to be the most well known sponge species in the world. Though there is speculation of a wild population, that may not necessarily be true. It is possible, that may have just found the last remaining survivors of the entire species. As such, it is important that we keep them protected. Cheers!<br />

Unlike all the other survivor game shows, this show will probably give the prize money to the individual that manages to raise the number of participants. Introducing the Ja<span style="font-family: inherit;">van Rhino, <i>Rhinoceros sondaicus</i>.</span><br />
<span style="font-family: inherit;"><br /></span>
<span style="font-family: inherit;">The Javan Rhino's last wild habitat is the Ujung Kulon National Park, where all 60 individuals are said to live. In the past, there used to be 2 other subspecies of Javan </span>Rhinoceros that live in Borneo and Vietnam. Today the Javan Rhino is the sole surviving subspecies still present in the wild.<br />

<tr><td class="tr-caption" style="text-align: center;">Only males of the Javan Rhinoceros species grow the horn above its nose</td></tr>
</tbody></table>
<br />
Javan Rhinoceros grow to about 1.7m in height and 4m in length, having lose folds of skin giving them an armour-like appearance. Its single namesake horn grows to about 25cm atop the male's nose, it is used to plow away vegetation and uproot plants for them to eat. Due to the similarities Javan Rhinoceros was once mistaken to be of the same species as the Indian Rhinoceros due to their similar appearances, it is now noted that the species is a smaller relative of the Indian Rhinoceros.<br />
<br />
As mentioned in the previous post on cheetahs, the Javan rhinoceros face the same problem of a small population, their genetic variability his been severely affected by large extinctions within their populations. Such events include those outside the sphere of human influence, for example, the Karkatoa volcanic explosion of 1883 which wiped out majority of the then Ujung Kulon Javan Rhinoceros population. The current population now present in the park is said to be a re-colonization of the species from other parts of Java.<br />
<br />
However, even in light of its current crisis, the Javan Rhinoceros population shows that it is still fighting for its species survival. This ray of hope comes in the form of, much to conservationist's delight, 3 healthy looking calves - 2 males and 1 female!<br />
<br />

</tbody></table>
Yet this is only the first of many steps to a successful recovery of the population. The population needs to grow bigger and establish itself in areas other than the park to prevent further loss of genetic material, or face a possible sudden extinction like what happen in 1883. There is still along way to go, but for now, let us celebrate this small victory.<br />

The common saying about not being able to change spots has been defied, once again, by the animal kingdom. Though I do not think what you have in mind is the same thing - I am referring to the process of grafting!<br />
<br />
Cheetahs (<i>Acinonyx jubatus</i>) are the fastest land animals, running up to 120 km/h in short bursts to bring down prey. They are also the last surviving species of the genus <i>Acinonyx</i>, the rest of the genus was said to have died in the late Pleistocene. This includes at least 4 other species in the genus and other <i>Acinonyx jubatus</i> subspecies. It is likely that the same extinction event caused a bottleneck effect. This meant that only a small number of the original population survived, leading to a huge lost in the genetic variability. Things only got worse for the cheetahs, genetically speaking. As surviving population multiplied, it led to inbreeding within the population. The inbreeding process caused severe impacts on the subsequent generations of cheetahs through high infant mortality rates . As such the population becomes smaller and smaller, even without taking into account external negative forces such as habitat destruction. This, in turn, made it more likely for inbreeding to occur as the cheetahs become more interrelated.<br />
<br />
<table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto; margin-right: auto; text-align: center;"><tbody>
<tr><td style="text-align: center;"><img src="http://www.babyanimalzoo.com/wp-content/uploads/2013/03/cheetah-cubs.jpg" style="margin-left: auto; margin-right: auto;" /></td></tr>
<tr><td class="tr-caption" style="text-align: center;">Cheetahs suffer from high infant mortality rates, making it difficult for population to expand</td></tr>
</tbody></table>
<br />
So then what has this have to do about changing spots and grafting? It is precisely because the above mention situation, individuals of species have become so genetically similar, and are able to accept skin grafts from each other. An experiment was conducted by O'Brien in 1983, where 7 unrelated cheetah pairs were given each others' skin as grafts, 6 were non-related and 1 was a pair of siblings. The results was that none of the grafts were rapidly rejected by its host, with majority of the grafts, 11 out of 14, being accepted without any rejection of sorts.<br />
<br />
Further studies by O'Brien inquires about how similar are the cheetahs genetically and the results showed 0 polymorphism in the genes and a slight degree of polymorphism in the proteins. Though there are other animals that survive with low polymorphism, such as the polar bear, such low levels of polymorphism are not naturally found in anywhere else in the feline family.<br />
Being so similar to each other does not give a species an advantage, in fact, it makes them more vulnerable to single selection pressure such as disease, that might cause its extinction, as the population does not have required variation to adapt.<br />
<br />
Even as the idiom sheds a negative light on leopards not being able to change their spots- perhaps it is better not being able to after all.<br />

Jellyfishes have two different forms in life, the polyps and the medusa. The medusa are more commonly recognized as jellyfishes, an umbrella like head with many tentacles streaming along after it as it bobs through the water. The polyps are a hidden side of the jellyfish life cycle many are oblivious about. In fact, how a jellyfish begins its life is as a polyp!<br />

Polyps, also known as scyphistomas, are small structures that fix themselves onto hard surfaces. Scyphistomas are usually found on the ocean floor, meaning they are benthic, and have tentacles to help it trap food and feed. These polyps then start to feed and mature and even multiply. Polyps were able to multiply through the formation of podocyst, these are able to bud off from one another developing into new polyps. This means that they reproduce asexually and the two polyps are genetically similar. Once matured, polyps can then start producing ephyras, which will mature into medusas, adult jellyfishes, within a matter of weeks. The process at which the polyp constricts itself to release the ephyras is known as strobilation. A single polyp can stobilate multiple times and is estimated to produce up to 15 ephyras per month. After strobilation, polyps will resume their daily business of eating and growing. </div>
<div>
<br />
Adult jellyfishes then go through the familiar process of sexual reproduction via external fertilization of the eggs. These eggs develop into larva and attach themselves onto hard surfaces, eventually, growing into polyps!<br />

In recent years, there have been reports of various increase in populations of jellyfishes. Cause of this phenomenon come from a variety of possible factors, all of which seemingly leading back to human interference with the ecosystem.<br />
From introduction of an invasive species of jellyfish into a ecosystem, to less competition for food due to over-fishing, and even eutrophication of the water, leading to conditions that favor the growth of jellyfishes. These high populations of jellyfishes adversely affect the ecosystem through uncontrolled predation of the lower trophic levels. This also means that less fish will be present in the waters and thus destroy fishing grounds, affecting the supply of fish to the market. Beaches that the blooms occur at will also have to be closed down for the safety of the swimmers, affecting the economy of the area.<br />
<br />
For a surprisingly transparent entity, it still holds many mysteries regarding its growth. This is especially true for the polyp phase of the life cycle. Thus, to understand how to prevent such blooms from getting out of hand, is essential to that scientist continue to study the jellyfish.<br />

Pandas are cute, they are lovable, they are, as some would say, the best of 3 worlds all rolled into one. Hence, it is of no surprise that everybody wants to save the pandas. Recently, there have been big waves made by Mei Xiang, a panda at the Smithsonian National Zoo, giving birth to twin cubs. This was done via artificial insemination on the 26th April. If you can recall, Singapore also had its own flurry of "Panda Porn" early this April too, with resident pandas going at it for 40 minutes. With all this action going on in the pen, are we actually progressing in saving these majestic creatures?</div>

It is said that there are approximately 1,600 wild pandas left in Central China, and an additional 300 pandas kept in various breeding centers in China and zoos around the world. With these low numbers present in the wild, it would seem that increasing the numbers of captive pandas to ensure genetic variability of the pandas remain viable, is the right thing to do. However, one cannot turn a blind eye to the astronomical amount of money pumped into to hosting a panda.</div>
<div class="separator" style="clear: both; text-align: left;">
<br /></div>
<div class="separator" style="clear: both; text-align: left;">
For starters, zoos must built a modern panda exhibit that is up to China's panda experts requirement. Then comes the costs of transportation of the pandas themselves, the yearly costs of transporting enough bamboos for the bears, and not forgetting the token sum paid to China yearly for the loans of the animal. In the cases of US zoos, they have to design a research program that helps too boosts the survival rates of wild pandas. All these easily adds up to millions of dollars, this is not including costs of supporting cubs, where twins are not a rare occurrences.</div>
<div class="separator" style="clear: both; text-align: left;">
<br /></div>
<div class="separator" style="clear: both; text-align: left;">
With the costs of hosting these animals being so high, why do zoos still insist on hosting them? This is because pandas have become the face conservation. Its significant shape can often be seen on the logos of the World Wildlife Fund (WWF). It garners public support for wildlife bringing to attention other animals of the plight. More importantly, it gives the public a face to gather behind to push for conservation and which animal better to do it then one that could help melt the hearts of young and old alike.</div>
<div class="separator" style="clear: both; text-align: left;">
<br /></div>
<div class="separator" style="clear: both; text-align: left;">
Yet, all the attention focused on breeding of giant pandas and conservation will not be enough to save the them. Remember, the end goal is to increase the <i>wild</i> population of giant pandas. Even as the number of captive pandas continue to climb, we would fall short of the objective if we fail to reintroduce them into the wild. With the Central China's bamboo forest still under the threat of the deforestation, perhaps we should turn our efforts away from breeding them for the time being and ensure the protection and restoration of their natural habitat. After all , what good will it be if the wild is no longer able to support pandas.</div>

<div class="separator" style="clear: both; text-align: left;">
I love animals in general, and the panda is adorable. However, I do wish for them to only be found in captivity. Everything in nature comes as a balance, and so we must learn to strike a balance too. Successful breeding of pandas is a step in the right direction but we must ensure they have a place to live after captivity if we are ever going to give the panda a fighting chance out in the wild.</div>
