More information: Deuknam An et al. Enhanced call effort in Japanese tree frogs infected by amphibian chytrid fungus, Biology Letters (2016). DOI: 10.1098/rsbl.2016.0018 A pair of researchers with Seoul National University has found that Japanese tree frogs infected with Batrachochytrium dendrobatidis (Bd) fungus make different advertisement calls than uninfected frogs. In their paper published in The Royal Society Biology Letters, Deuknam An and Bruce Waldman explain their study and results and what impact the change in calls has on the frogs. Deadly amphibian fungus may decline, study says © 2016 Phys.org Bd causes a disease called chytridiomycosis in amphibians, where the skin is depleted and the immune system compromised—in most species it has been found to be deadly, killing off millions of frogs, salamanders and other species. Some experts believe it could ultimately wipe out a third of all amphibian populations worldwide. The disease was first noted by scientists in the 1990’s but since that time, researchers have found preserved samples going back as far as 1938. Scientists around the world have been working to better understand the fungus that causes the disease in hopes of perhaps preventing its spread further—one important area of research surrounds the Japanese tree frog, which become infected, but do not usually die from the associated disease. To learn more An and Waldman focused their attention on 42 of the male specimens in the wild, making recordings of their mating calls. They looked for such things as call duration, pulse length, pitch and how often the calls were repeated. They also tested the frogs for infection.In looking at their data, the researchers found that nine of the frogs were infected, and surprisingly, they were also the group that appeared to put the most effort into their mating efforts—their calls were longer and faster—this was surprising because another symptom of chytridiomycosis is lethargy. Also interesting was that the females in the area generally found the more energetic calls more enticing than normal, which meant the infected frogs found more success mating than those that were uninfected.The researchers offer two perspectives on their observations—either the fungus is causing the frogs to behave differently so as to improve its infection abilities (male frogs passed on the fungus to females during mating), or the male frogs were simply reacting to their stressed condition by attempting to reproduce earlier, due to an expected shortened lifespan.

Kolkata: The state Women & Child Development & Social Welfare department has urged the state Labour department to work out the feasibility of bringing private placement agencies under the ambit of some control.”A number of women go missing and then are trafficked on the pretext of lucrative jobs. Hence, we are trying to have a database of the private placement agencies and for this we have sought assistance from the Labour department. We have already given them a draft regarding our plan,” said Shashi Panja, minister of state for Women & Child Development & Social Welfare on the sidelines of a cumulative workshop for Also Read – Rain batters Kolkata, cripples normal lifeimplementation of State Plan of Action against human trafficking. It may be mentioned that in December 2014, the department had launched State Plan of Action Against Human Trafficking in Women and Children (SPAHT) as a pilot project in Jalpaiguri and South 24-Parganas. Bengal was the first state in India to launch such a plan. “We have now decided to roll it out throughout the district. UNICEF, our key technical partner in the SPAHT process, and various other NGOs working with women and child trafficking have been roped in. We have Child Protection Committees (CPCs) at every block in the state that will organise towards finalising the action plan,” Panja said. Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killedThe implementation of SPAHT is visualised through the convergence of various departments and agencies, where victims remain central. The department has come out with a handbook stating the responsibilities of government departments like Youth Affairs, School Education, Home, Panchayat & Rural Development, Urban Development, Public Works Department, Health & Family Welfare and Industries to curb child and human trafficking. According to a senior official of the department, it has now CPC’s in 2308 wards under the different urban local bodies and 49646 gram sansads across the state. The committee consists of teachers, doctors and anganwadi workers etc. The SPAHT uses a child-rights framework to comprehensively map the responsibilities of key government departments that are tasked with affirmative action for children. These responsibilities are operationalised through the implementation of central and state government schemes, as well as specific actions taking into account the states’ local needs and critical issues. “The Swayangsiddha project to curb human trafficking is also being rolled out in the entire state by the state Criminal Investigation Department (CID). We are also arranging rehabilitation of the victims after they are rescued,” a senior official of the department said.
In the winter season, safeguard yourself against dry and dehydrated skin. Give yourself oil massages, use cream-based products and apply cold cream before sleeping, says an expert.Here are some tips:* Turn to cream-based products early: If winter is approaching, it’s time to turn to skincare products that have cream-based thick moisturizers. So, your light water-based moisturizer will pave way for a heavy and thick cream. Switch over to a milder facewash and use a sunscreen that has moisturiser. While removing make-up too, use moisturizing cleansers and toners. Also Read – Add new books to your shelf* Give yourself oil massages: Just when you wake up in the morning, give yourself 15 minutes to apply warm oil all over the body, including on the face and the scalp. Leave it for an hour as you finish your morning chores. Then take a bath as usual and proceed for the day. This will go a long way in keeping your skin healthy, not just for the winter, but for a long time.*Exfoliate and steam: As we apply more creams, more oil and more products to stave off the dehydrating winter chill, the skin pores sometimes get blocked. For this purpose, exfoliating skin once or twice every ten days is recommended. Use a gentle scrub in circular motions on the skin to remove dead cells and clean up the skin. Once a month, also take recourse to steaming therapy. This will help soften the skin, open pores, and remove white heads and acne. Also Read – Over 2 hours screen time daily will make your kids impulsive* Nourishing skin procedures: Visit a dermatologist just before the onset of winters and seek a good solution for skin dryness. Deep moisturizing hydra facials once a month can be of much help in treating, even preventing excessive dryness. * Drink water: The icy cold weather often discourages us from drinking sufficient water and we tend to increase our skin dehydration due to this reason. Keep heated water in a thermostat. But keep drinking water to keep skin hydrated and prevent lips from cracking. * Feet care: Cracked heels, irritated soles, and itchy and swollen feet can be a major irritant, but feet are often at the lowest end of our priority. Apply cold cream to feet every night before going to bed. Use an exfoliating agent to remove jagged and hard skin from the heels once every fortnight. It is extremely important to wear warm, preferably woollen socks in winters.* Diet is important too: It is important to take a good intake of vitamin and minerals rich foods during winters to boost immunity and health. Consume a lot of fruits and vegetables, and take diet rich in Omega 3 fatty acids like fish to boost skin health and nourishment.
