Bengal Slow Loris

 The Bengal Slow Loris




The Bengal Slow Loris is 34-38 centimeter in length and weighs 650-2,000 gram. Its dorsal fur is light brown, with much lighter ventral fur. The face is creamy white with triangular patches of dark fur around the eyes, which are occasionally connected via a fork to the dark stripe on the head. The dark head-stripe occurs at the middle of the head that changes to a dark brown-black at the shoulders and continues as a dorsal stripe to the middle of the back. The species does show some seasonal variation in pelage but this is not well documented






Last month while researching for a primate tour in India I came across a unique primate – The Slow Loris. Not only are these one of 10 smallest primates in the world, they are also the only venomous primate in the world. Yes! Venomous primate!

With my interest piqued, I started studying more about this close cousin of ours. The Slow Loris comes from the genus Nycticebus which consists of four species: Pygmy Slow Loris, Javan Slow Loris, Sunda Slow Loris and our very own Bengal Slow Loris. The Bengal Slow Loris has the largest distribution of all the slow lorises and can be found in Bangladesh, Cambodia, southern China, Northeast India, Laos, Burma, Thailand, and Vietnam.



It is nocturnal and arboreal, occurring in both evergreen and deciduous forests. It prefers rainforests with dense canopies, and its presence in its native habitat indicates a healthy ecosystem. It is a seed disperser and pollinator, as well as a prey item for carnivores such as Pythons and Hawk eagles. Its diet primarily consists of fruit, but also includes insects, tree gum, snails, and small vertebrates. The species lives in small family groups, marks its territory with urine, and sleeps during the day by curling up in dense vegetation or in tree holes. It is a seasonal breeder, reproducing once every 12–18 months and usually giving birth to a single offspring. For the first three months, mothers carry their offspring, which reach sexual maturity at around 20 months. The Bengal Slow Loris can live up to 20 years.

Now since we have already told you that this is a venomous primate let us understand a couple of things: How does the ‘venom’ work? Are they venomous or poisonous? And what’s the difference between the two.

To begin let us first understand “brachial glands”. The flexor surface or the ventral side of the elbow has a slightly raised but barely visible swelling termed the brachial gland. Observations from captive slow lorises show that when the animal is disturbed during handling, they secrete about 10 microliters of clear, strong-smelling fluid in the form of an apocrine sweat (exudate) from their brachial gland. Usually, male and female slow lorises assume a defensive stance when disturbed. They bend their heads downwards between uplifted forelegs, rubbing the brachial gland exudate onto their head and neck. Slow lorises frequently lick their own brachial gland regions and wipe their brachial gland against their head. The brachial gland is active in lorises as young as 6 weeks old.


The main difference a venomous and a poisonous animal is that a venomous animal injects toxins into its victim’s body by bite or sting. A poisonous animal, on the other hand, produces toxins that are poisonous once inhaled or ingested like a Puffer Fish. Medical literature shows that human – Slow Loris injuries come from Slow Loris bites and not from ingesting their toxins. So, are slow lorises venomous? Well, not quite….


Lorises have got strong jaw muscles and pointed teeth with cutting edges easily piercing human skin or thin gloves. Health problems after Slow Loris bites may be either due to presence of a toxin produced by the animals, due to bacteria and viruses transferred by bites or due to an anaphylactic shock (extreme allergic reaction). Loris brachial gland secretion includes two toxins, made inactive by inhibitors; when mixed with saliva, after licking of the brachial glands, the enzymes from the saliva break down the inhibitors and make the saliva-secretion mixture toxic.

Anaphylactic shock: in people, regularly in contact with slow lorises, saliva may repeatedly come into the body through tiny, maybe invisible wounds. If the Loris keeper develops an allergy against this saliva, an allergic shock is possible (independent from the quantity of substance causing it, within seconds to minutes, in one case described lasting two hours), although this is a rare disease. Symptoms of anaphylactic shock may be: initially burning tongue and throat, a sensation of heat, red, itching skin, wheals, very low blood pressure, shock, convulsions of muscles (pain), pain in the heart and kidney region, respiratory problems (constriction of airways), heart problems, and possibly unconsciousness. Occurrence would make an immediate call for medicinal help necessary; first aid: measures against shock such as lying posture with legs a bit higher, assuring sufficient blood supply for necessary organs.

Slow lorises have needle-like teeth called dental combs or tooth combs on their lower jaw. Paired with the constant licking of the brachial gland, it is not surprising that one would assume the dental comb plays a part in injecting brachial gland exudate into unsuspecting victims. However, this is not the case, based on these published reports, it seems that Slow Loris bites are not venomous the reaction is largely to the exudate’s allergen secreted by the brachial glands which is like the Fel d 1 allergen in domestic cats… just more potent I guess.

The biggest challenge that these beautiful creatures face today is the meat and pet trade. People will often buy Loris as pets as they look adorable however, as in the case of all exotic pets most of these pet owners do little to no research about the species and have no clue about how to raise one in a home environment often unknowingly creating an environment or a situation harmful for the species.


IMPORTANT  POINTS TO REMEMBER

The Bengal slow loris is a gum-eating, nocturnal, tree-dwelling primate species found in northeast India.

Limited information on its status and ecology is the main hindrance to developing a conservation strategy for this species in India, state experts.

The species, which is listed as Endangered in the International Union for Conservation of Nature’s Red List, is heavily hunted and traded despite being legally protected under the Wildlife Protection Act, 1972.

Agricultural Subsidies & Air Pollution

IMPACT OF Agricultural Subsidies ON Air Pollution 





What is the issue? 

 Our current system of subsidies is a big reason for air pollution.

 So, some changes could be made in the subsidies of the power, fertilizer and procurement fronts.

What is the situation? 

 People in Delhi and Indo-Gangetic Plain are choking due to air pollution.

 As winter dawns, the wind slows, temperatures drop, and suspended particulate matter (PM) accumulates.

 The high pollution in Delhi and its surrounding is due to the congested traffic, dust, construction, waste

burning, etc,

 It gets a top-up from paddy-stubble burning in Punjab, Haryana and Western Uttar Pradesh.

What contributes to air pollution? 

 Agriculture’s contribution to air pollution runs even deeper than what happens between crop seasons.

 Atmospheric ammonia comes from fertiliser use, animal husbandry, and other agricultural practices.

 This combined with emissions from power plants, transportation, and other fossil fuel burning form fine

particles.

 Agriculture is a victim of pollution as well as a perpetrator.

 Particulate matter and ground-level ozone (from industrial, power plant, and transportation emissions among others) cause losses in crop yields.

 Ozone damages plant cells, handicapping photosynthesis, while particulate matter dims the sunlight that

reaches crops.

What is the irony? 

 The irony of agricultural pollution is that taxpayers are essentially paying for it through a system of subsidies.

 These subsidies motivate the very behaviors that drive the agricultural emissions that the taxpayers breathe.

How does subsidy contribute to air pollution? 

 Free power - hence ―free‖ water, pumped from the ground - is a big part of what makes growing rice in these areas attractive.

 Open-ended procurement of paddy, in spite of bulging stocks of grains with the Food Corporation of

India, adds to the incentives.

 Subsidies account for almost 15% of the value of rice being produced in Punjab-Haryana belt.

 Fertiliser, particularly urea in granular form, is highly subsidised.

 Urea is one of the cheapest forms of nitrogen-based fertiliser, but it is also one of the first to release ammonia

into the air.

 This loss of nitrogen leads to a cycle of more and more fertiliser being applied to get the intended benefits for

crops.

What could be done? 

 An important element to correct in the policy matrix is the policy of subsidies on power, fertilisers and

procurement.

 The nature of support to farmers should be shifted from input subsidies to investment subsidies.

 A diversification package, equally contributed by the Centre and states, may be done to reduce agricultural

pollution.

 The approach to diversification has to be demand-led, with a holistic framework of value chain, and not just

focused on production.

 On the fertiliser front, instead of massive subsidisation of urea, the farmers could be given an input subsidy

in cash on per hectare basis.

 Government procurement of paddy from farmers burning stubble in their fields may also be restricted.

 Taken together, these measures could double farmers‘ incomes, promote efficiency in resource use, and reduce

pollution.

 Released norms on NOx Emissions 

 NOx or Oxides of nitrogen are a criteria pollutant emitted on burning coal.

 NOx is harmful, it also triggers the formation of ground level ozone and leads to secondary particulate matter worsening health risks and needs to be controlled.

 Coal-based power plants, besides the transport sector, are a major source of this pollutant.

 There were no limits placed to control emissions of NOx from power plants before 2015.

 The MoEF&CC introduced limits of 300 mg / Nm3.

 Recently Union Ministry of Environment, Forest and Climate Change (MoEF&CC) has relaxed NOx emission

norms.

 It has been relaxed to 450 mg / Nm3, from 300 mg / Nm3, for power stations commissioned between 2003

and 2015.

 The relaxations were brought about as the power sector strongly lobbied watering down the norms, alleging it was not possible to meet the 300 mg / Nm3 standard at all loads.

 Boiler companies assured government that a NOx emission level of 450 mg / Nm3 can be achieved by combustion modification.

 To meet emissions below it would mean installation of slightly expensive pollution control equipment like

selective non-catalytic reactors (SNCR) will be required.

Human Emissions of Nitrous Oxid

 According to recent findings Human emissions of

nitrous oxide (N2O) increased by 30 per cent between

1980 and 2016.

 Its global concentration levels increased from 270 parts

per billion (ppb) in 1750 to 331 ppb in 2018, a jump of

20 per cent.

 The growth has been the quickest in the past five

decades because of human emissions.

 It has also found that a major proportion of the N2O

emissions in the last four decades came from the

agricultural sector, mainly because of the use nitrogen-

based fertilisers.

 Most N2O emissions have come from emergin

World’s First ‘Energy Island’ to be built by Denmark


World’s First ‘Energy Island





 Denmark, the nation that built the world’s first offshore wind farm, has agreed to an ambitious plan for another global first – an energy island in the North Sea which could eventually be capable of supplying energy to a history-making 10 million homes. The move will create a critical boost to the world’s offshore wind capacity.

The first hub and spoke  scheme will involve building an island 80 kilometres off the Danish coastline to act as the transmission centre for hundreds of wind turbines surrounding it. It is the largest construction project of Danish which is around $34billon

The project is also a potential blueprint for other coastal nations to develop their own green energy sources. “It’s in Danish waters, yes, but it could conceptually be in any other country."

Energy hub for the world

The initial phase for the artificial island is around the size of 18 soccer pitches. Initially, the North Sea hub will be capable of producing 3 gigawatts of electricity, but the plan is to scale up to 10 gigawatts, which is nearly one-and-a-half times Denmark’s current needs.

As well as supplying other European countries with electricity, the goal is to use the new offshore island to produce green hydrogen from seawater, which can also be exported. Large batteries on the island will store surplus electricity for use when demand is high.

Although the Danish government will own a majority stake, private companies will be invited to join a public/private partnership to build the project. Power will be supplied by as many as 600 giant wind turbines, each standing up to 260 metres tall.

DENMARK‟S ARTIFICIAL ENERGY ISLAND PROJECT. IMPORTANT POINTS

 

◾️ The Danish government approved a plan to build an artificial island in the North Sea as part of its effort to switch to green energy.

◾️An energy island is based on a platform that serves as a hub for electricity generation from surrounding offshore wind farms.

 ◾️The artificial island will be located about 80 km into the North Sea and the majority of it will be owned by the Danish government.

WAYS TO PROTECT ENVIRONMENT

5WAYS TO PROTECT YOUR ENVIRONMEN






 Unfortunately, humans have not been very good stewards of the Earth over the years. To protect the environment and preserve the planet for our children and future generations, we all need to take proactive steps toward cleaner living habits.

Most of the damage to our environment stems from consumption: what we consume, how much we consume and how often.

Whether it’s gas, food, clothing, cars, furniture, water, toys, electronics, knick-knacks or other goods, we are all consumers. The key is not to stop consuming, but to start being mindful of our consumption habits and how each purchase or action affects the ecosystem.

The good news is that it’s often not too difficult, expensive, or inconvenient to become more environmentally friendly. It can even be a fun challenge to implement among your family or coworkers. And though small changes at the individual level may seem trivial, just think how much cleaner the planet would be if everyone adopted even a few of the following behavior modifications.

1.Don’t buy single-use plastics.
Pop a flask or reusable bottle in your bag next time you are out and about. Make this a habit and cut your weekly bottle buying altogether, stopping 52 bottles ending up in landfills and oceans.

More than 2,600 plastic bottles a year would be stopped from entering our environment altogether if just 50 people packed a flask instead of buying a bottle. Small changes can make a big difference


2.Reduce our ecological footprint: 







Reducing our ecological footprint means placing less demand on nature .

  • Recycle your rubbish and participate in or help organize recycling campaigns.
  • Avoid littering and participate in or help organize litter clean-ups .
  • Use less plastic by, for example, carrying a reusable water bottle, saying no to disposable straws and cutlery, avoiding plastic toys, and bringing your own shopping bags.
  • Swap toys, movies, and books instead of buying new ones.
  • Donate, recycle, and repair electronic devices.
  • Use less water when brushing teeth, taking a shower, or washing the dishes.
  • Use less electricity by turning off lights and electronic devices when not in use, using energy-saving light bulbs, and hanging clothes to dry.
  • Use public transport, share a journey with friends (e.g., car-sharing), cycle, or walk when possible.
  • Use less paper by not printing unnecessary things and reading e-books.
  • Turn down the air conditioning when it is hot and use fans if you are still hot-they use much less pow

3.Re-use and Recycle.



  Reducing the amount of “stuff” you consume has the greatest benefits for the planet. It’s best to avoid waste in the first place, so think more carefully about your purchases.

Re-using items saves the natural resources and energy needed to manufacture new ones - as well as saving money.

4. Skip the Bottled Water



Opt for a reusable water bottle to save money and help the environment. Install a water filter in your home or use a Brita filter. Besides, tap water is already stringently monitored by the government, so bottled water  isn’t necessarily safer.

5. Compost Your Food.

up



There are many benefits for environment composting. Not only do you reduce the amount of food going into the landfill thus reducing greenhouse gas emissions, you also can use it to help grow your own sustainable garden.

Glossanodon macrocephalus(Kerala argentine)

 

New family of prehistoric fishes discovered in Kerala


A team of researchers has discovered a new deep sea fish species in Kerala waters. Glossanodon macrocephalus (common name Kerala argentine) with whitish and Silvery body


In  the new family of bony freshwater fish  from paddy fields of Kerala. It is believed that this fish has lineage going back to Gondwanaland and has survived even after the parting away of the Asian and African continents began some 125 million years ago.

Researchers from the Indian Institute of Science, Education and Research (IISER), Pune, Kerala University of Fisheries and Ocean Studies (KUFOS), Nirmalagiri College in Kerala, Natural History Museums in London and Berne, along with Senckenberg Natural History Collections, Germany, were part of the discovery of the fish family named Aenigmachannidae.


As the researchers suspected, the fish was new to science. They named it the ‘Gollum snakehead’ as it is a subterranean creature, spending most of its life underground .

But the discovery had bigger implications than simply being a new species. Another snakehead species – the Mahabali snakehead – had also been collected in Kerala a few months before and was published as a new species after the Gollum snakehead had been described. Rajeev, Ralf and an international team of ichthyologists recognised many clear similarities between the Gollum and the Mahabali, and proved that not only were the two species new to science, they were actually members of a whole new family of fish.

ZABO RAIN WATER HARVESTING

 Zabo WATER conservation




The zabo (the word means 'impounding run-off') system is practiced in Nagaland in north-eastern India. Also known as the ruza system, it combines water conservation with forestry, agriculture and animal care.
Villages such as Kikruma, where zabos are found even today, are located on a high ridge. Though drinking water is a major problem, the area receives high rainfall. The rain falls on a patch of protected forest on the hilltop; as the water runs off along the slope, it passes through various terraces. The water is collected in pond-like structures in the middle terraces; below are cattle yards, and towards the foot of the hill are paddy fields, where the run-off 

It is an ingenious method of catching rainwater from running off the mountains practised in Kikruma in Nagaland. It involves the preservation of forests on the hilltops as they are the catchment for the water. At the next level are the ponds dug out to hold rainwater, which is brought there through small channels. The water is passed through cattle yards and carries the dung and urine of the animals to the fields below – perfect to meet the nutritional needs of the soil. The paddy fields are also used to rear fish, yielding about 50-60 kilogrammes of fish per hectare as an additional output. A huge variety of medicinal plants and herbs grow on the embankments of the ponds. The ponds are constructed to distribute water evenly. Inlet channels are dug to carry water from one pond to the next. The zabo system has not been replicated elsewhere.

Biodigester technology



Biodigester technology 




Human waste disposal in innocuous form is an ever growing problem leading to aesthetic nuisance, threat of organic pollution & several infectious diseases in epidemic proportions due to contamination of ground water and drinking water resources in highly populated and developing countries, like India. Less than 30% of Indians have access to the toilets. In rural areas about 10% of houses have toilets and rest of the people go to open defecation. Population in the cities although have better access to the toilets but only to the tune of ~70%. Untreated waste is responsible for several diseases like, dysentery, diarrhoea, amoebiasis, viral hepatitis, cholera, typhoid etc. taking the life of lakhs of children annually.


Biodigester technology has been developed by Defence Research Development Organisation (DRDO) for resolving the problems of un-decomposed human waste. The innovation degrades and converts the human waste into usable water and gasses in an eco-friendly manner. The generated gas can be utilized for energy/ cooking and water for irrigation purposes.


The process involves the bacteria which feed upon the faecal matter inside the tank, through  process which finally degrades the matter and releases methane gas that can be used for cooking, along with the treated water.

What is a biodigester?

A biodigester is a system that biologically digests organic material, either anaerobic (without oxygen ) or aerobically (with oxygen). Microbes and other bacteria break down organic materials in a biodigester. 

WHY IN NEWS

Biodigester Technology' was recently in news as Defence Research and Development Organisation (DRDO) will install its eco-friendly bio-digester units across the facilities operated by Maharashtra Metro Rail Corporation (MAHA-METRO), which help conserve water and protect the environment.
