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 overSponsored Article published by Mike Gaworecki The African wild dog (Lycaon pictus), a native of sub-Saharan Africa, is listed as Endangered on the IUCN Red List, which reports that there are only an estimated 6,600 adults in 39 subpopulations left in the wild — and that their numbers continue to decline due to ongoing habitat fragmentation, conflict with humans, and infectious disease.Compounding these threats to the species’ survival, according to a paper published in the Journal of Animal Ecology yesterday, climate change appears to be increasing the mortality rate for African wild dog pups.Researchers discovered that the packs spend less time hunting in hot weather. They also found that more pups died as the days got hotter, which they theorize is because, simply put, decreased hunting time means less food to feed the young. New research suggests that African wild dogs’ chances of survival might be dealt a serious setback as global temperatures continue to rise.The African wild dog (Lycaon pictus), a native of sub-Saharan Africa, is listed as Endangered on the IUCN Red List, which reports that there are only an estimated 6,600 adults in 39 subpopulations left in the wild — and that their numbers continue to decline due to ongoing habitat fragmentation, conflict with humans, and infectious disease.Compounding these threats to the species’ survival, according to a paper published in the Journal of Animal Ecology yesterday, climate change appears to be increasing the mortality rate for African wild dog pups.Researchers with ZSL (Zoological Society of London), the Botswana Predator Conservation Trust, and the African Wildlife Conservation Fund monitored 73 African wild dog packs in Botswana, Kenya, and Zimbabwe through the use of tracking collars. They discovered that the packs spend less time hunting in hot weather. They also found that more pups died as the days got hotter, which they theorize is because, simply put, decreased hunting time means less food to feed the young.“Our findings suggest a consistent impact of high ambient temperatures on African wild dog behaviour and reproduction,” the authors of the study write. “High ambient temperatures were associated with reduced activity, longer inter-birth intervals, and poorer pup recruitment.” They add that “Impacts of high ambient temperatures on reproductive success were apparent in all three study areas, irrespective of whether or not reproduction was seasonal.”Adult wild dogs with pups in Zimbabwe.

At the same time, the researchers observed a drop in the average number of pups surviving in each pack, from five to three.African wild dogs are not a species typically seen as possessing traits that would make them particularly vulnerable to the effects of a changing climate, the researchers write in the study. That makes their findings all the more important.“Our study shows the truly global impact of climate change,” Rosie Woodroffe of ZSL’s Institute of Zoology and the study’s lead author said in a statement. “When most people think about wildlife in a changing climate, they think of polar bears clinging to melting ice, but even species who have adapted to tropical weather are being impacted by the changes to their environment.”Woodroffe added that she and her team are now focused on identifying conservation interventions that might help mitigate the impacts of global warming on African wild dogs and determining where those efforts will be most effective.It’s estimated that there may be as few as 700 packs of African wild dogs left in the wild, and they’ve all been forced into a tiny fraction of their original territory as human populations have encroached further into rural areas.A study published last week that looked at range contractions for the world’s large terrestrial carnivores found that the vast majority of them — 80 percent — have seen their global territory shrink by 20 percent or more. The African wild dog was one of the hardest hit in this regard, having lost some 93.2 percent of its historical range.The authors of the Journal of Animal Ecology study note that other large carnivores in Africa are unlikely to suffer the same impacts due to climate change, or at least not to the same degree as African wild dogs: “These impacts of high ambient temperatures on wild dogs reflect their largely diurnal activity pattern, and probably their cursorial hunting habit. Other large African carnivores may be less affected because they are more nocturnal (lions, leopards, hyaenas) or engage in short daytime hunts which do not lead to over-heating.”There are viable populations of the dogs in several national parks and game reserves, particularly in East Africa and in Southern Africa. Despite numerous successes in preserving biodiversity and habitat, however, protected areas aren’t impervious to the effects of climate change.“Worryingly, this new threat may be affecting wild dogs deep inside wildlife areas where we would expect them to be protected from human impacts,” she said. “With habitat fragmented and destroyed in cooler areas, wild dogs have literally nowhere to go. Sadly, climate change may bring extinction a step closer for this amazing species.”A pack of wild dogs in Kenya. Photo Credit: ZSL / Helen O’Neill.A wild dog in Kenya.
