Pesticides could be painting black howler monkeys yellow in Costa Rica

Pesticide use on agricultural plantations may be shifting the color palette of howler monkey fur in Costa Rica, a team of scientists has found.Mantled howler monkeys (Alouatta palliata) are typically pretty understated in terms of color, often carrying a dark coat of fur with a few flecks of orange on their sides. But in just the past five years, more monkeys have been appearing with larger splashes of yellow fur.A male mantled howler monkey (Alouatta palliata) at the Caña Blanca wildlife sanctuary on the Golfo Dulce, Costa Rica. Image by Steven G. Johnson via Wikimedia Commons (CC BY-SA 3.0).Since the early 2000s, scientists have been probing the genetics of primates in Costa Rica, including mantled howler monkeys. An early study revealed that these animals’ genes don’t vary very much, and all 205 monkeys in that study had the same genetic sequence, called a genotype, that codes for a fully dark coat.About five years ago, however, researchers began finding the peculiar yellow coloring. All told, the authors know of at least 21 individuals with it. At first, those splashes often just covered a small part of a monkey’s body, perhaps a hand or a section of the tail. But over time, researchers have noticed that more of the affected monkeys’ bodies are yellow. Some now have little black fur at all.A mantled howler monkey calling, in Tortuguero, Costa Rica. Image by Arturo de Frias Marques via Wikimedia Commons (CC BY-SA 4.0).The team’s hypothesis, reported online Oct. 31 in the journal Mammalian Biology, is that sulfur in pesticides used on banana, pineapple and oil palm plantations — frequently applied in copious amounts — could be triggering the effect. Indeed, most of the monkeys with yellow fur live near these operations, where they likely pick up sulfur-containing chemicals when they eat the leaves of nearby trees. The researchers believe the yellow-colored monkeys are making less of the dark pigment called eumelanin and more of a compound called pheomelanin, which contains sulfur and produces lighter-colored skin cells and hair follicles.They write that further research could bring the causes of this change into sharper focus, as well as the ramifications to the monkeys themselves. They share the forests of Costa Rica with six cat species that may hunt howler monkeys, and it remains to be seen whether the yellow patches might make them a more visible target.Banner image of a mantled howler monkey by Scott Robinson via Wikimedia Commons (CC BY 2.0).Citations Galván, I., Jorge, A., Sánchez-Murillo, F., & Gutiérrez-Espeleta, G.

Good effort trying to be objective in this article. I would like to give a constructive feedback which could help in clearing things up.1. It is mentioned that planting trees in village common lands will have negative affects socially and ecologically. There is no need to even have to agree or disagree with it, because, you also mentioned the fact that Cauvery Calling aims to plant trees only in the private lands of the farmers. So, plantation in the common lands doesn’t come into the picture.2.I don’t see that the ecologists are totally against this project, but just they they have some concerns, mainly in terms of what species of trees will be planted. And because there was no direct communication between the ecologists and Isha Foundation, it was not possible for them to address the concerns. As you seem to have spoken with an Isha spokesperson, if you could connect the concerned parties, it would be great, because I see that the ecologists are genuinely interested in making sure things are done the right way.May we all come together and make things happen.Rare Amazon bush dogs caught on camera in BoliviaCarrot1 Feba very good iniciative to be fallowed by the ranchers all overSponsoredlast_img read more

New social housing for Cape Town

first_img“We are also saying, in areas where we can, let us go high rise instead of going wide on the ground. This means we don’t have to wait for vast lands to be unlocked for development.” Transforming inner cities 25 March 2011 “We have always said where we stay should be where play, where we pray and where we work,” Sexwale said. Launching the R75-million Drommedaris Brooklyn Social Housing project in Cape Town this week, Human Settlements Minister Tokyo Sexwale said it was important to house people closer to their place of work as well as other amenities. The project, located on Koeberg Road in Brooklyn, has been designed to take advantage of the Cape Town’s proposed Bus Rapid Transit routes. This means people will not spend longer than necessary getting to and from work. SAinfo reporterWould you like to use this article in your publication or on your website? See: Using SAinfo materialcenter_img Sexwale said the project sets a good example of the department’s social housing strategy to transform the inner cities, revitalise strategic nodes of development and to address economic, social and spatial dysfunctionalities. The launch was also attended by the Public Works Minister Gwen Mahlangu-Nkabinde, Western Cape Premier Helen Zille and Western Cape Human Settlements MEC Bonginkosi Madikizela. The project is part of the department’s social housing initiative, that aims to provide accommodation for people who do not qualify for government subsidised houses while also not being able to access home loans from banks. “We want to revitalise and transform our inner cities by creating housing opportunities and giving a chance to people who would otherwise be overlooked by banks for mortgage bonds while not qualifying for the subsidised houses,” Sexwale said. “What we are witnessing today is the realisation of our long term objectives of ensuring that people who earn between R3 500 and R7 000 are provided with appropriate accommodation closer to work opportunities in the process improving economic conditions.”last_img read more

first_imgKochi, Jan 6 (PTI) Anti-Submarine Warfare (ASW) School & Diving Schools team won the regatta trophy (Cock) for the fourth consecutive year in the Kochi Area Pulling Regatta 2017 organised by the Southern Naval Command (SNC) in the Ernakulam Channel here today. INS Garuda secured the runners up position in the keenly contested championship which was held under five different categories over a course of 1.6 Km in the Ernakulam Channel with Venduruthy-Vikrant Bridge being the starting point. Six teams from all the units of SNC at Kochi participated in the regatta, a Navy release said here. The boat Pulling Regatta is one of the most prestigious Naval sports activity conducted in the Navy on 27 feet long “Whaler” boats with a crew of five pullers and one coxswain each, similar to the famous snake boat race of Kerala. This activity is a signature event of the Navy signifying the highest standard of physical and mental application, team work, coordination and sustained hard work. Vice Admiral AR Karve, Flag Officer Commanding-in-Chief, Southern Naval Command who was the Chief Guest, presented the awards to the winners and runners up in the presence of a large gathering of naval personnel. Awards for Kayaking and Canoeing Championship for the year 2016-17 were also presented on this occasion in which INS Garuda was declared the winner, the release said. In addition to this, the Admiral, used this opportunity to present the Godavari Trophy to INS Venduruthy and Navigation and Direction School for the maximum points from all the sporting activities held last year.
