This 2015 video is about the Niokolo-Koba National Park in Senegal.

In developing nations, national parks could save endangered species

Summary: A new study of animal populations inside and outside a protected area in Senegal, Niokolo-Koba National Park, shows that protecting such an area from human interaction and development preserves not only chimps but many other mammal species.
The West African chimpanzee population has declined by nearly 80 percent in recent decades. Habitat loss is threatening their livelihoods across the continent, and especially in Senegal, where corporate mining has started eating up land in recent years.
The geographical distribution of West African chimps overlaps almost perfectly with gold and iron ore deposits, and unfortunately for the chimps, mining is a key piece of the country’s development strategy, said Stacy Lindshield, a biological anthropologist at Purdue University.
Extractive industries are already improving people’s livelihoods and promoting investment and infrastructure development, and researchers are trying to find a way to protect Senegal’s chimps without surrendering these benefits. Many of Earth’s animal species are now dying off at accelerated rates, but as human’s closest living relatives, they tend to tug at our heart strings. Chimps are scientifically important, too — because they participate in collective activities such as hunting and food-sharing, they’re often studied by social science researchers.
A new study of animal populations inside and outside a protected area in Senegal, Niokolo-Koba National Park, shows that protecting such an area from human interaction and development preserves not only chimps but many other mammal species. The findings were published in the journal Folia Primatologica.
“We saw the same number of chimpanzee species inside and outside the park, but more species of carnivores and ungulates in the protected area,” Lindshield said.
Although habitat loss is the biggest threat to West African chimps, they’re sometimes killed for meat. This is uncommon in Senegal, where eating chimpanzee meat is a taboo — people think chimps are too similar to humans to eat. But this isn’t the case in other West African countries, where researchers might see a bigger difference in chimp populations inside and outside protected areas. National parks could be especially effective at protecting chimps in these nations.
The difference in the number of species of carnivores and hooved animals (known as ungulates), inside and outside the park was stark — their populations were 14 and 42 percent higher in the park, respectively. This is in sharp contrast with what Lindshield was hearing on the ground in Senegal: There’s nothing in the park; all the animals are gone.
“There were qualitative and quantitative differences between what people were telling me and what I was seeing in the park,” she said. “Niokolo-Koba National Park is huge, and the area we study is nestled deeply in the interior where it’s difficult for humans to access. As a consequence, we see a lot of animals there.”
Hunting practices and human-carnivore conflict are two big reasons for ungulates thriving inside the park. These animals are frequently targeted by hunters, and some carnivore species turn to livestock as a food source when their prey species are dwindling, creating potential for conflict with humans. Because the two sites are relatively close geographically and have similar grassland, woodland and forest cover, the researchers think human activity is the root of differences between the two sites.
Lindshield’s team conducted basic field surveys by walking around the two sites and recording the animals they saw. They also installed camera traps at key water sources, gallery forests and caves to record more rare and nocturnal animals.
“We’re engaging in basic research, but it’s crucial in an area that’s rapidly developing and home to an endangered species,” Lindshield said. “This provides evidence that the protected area is effective, at least where we are working, counter to what I was hearing from the public. The management of protected areas is highly complex. Myriad challenges can make management goals nearly impossible, such as funding shortfalls or lack of buy-in from local communities, but I think it’s important for people to recognize that this park is not a lost cause; it’s working as it’s intended to at Assirik, especially for large ungulates and carnivores.”
Lindshield hopes her future studies will uncover not only which species exist in each site, but population sizes of each species. This metric, known as species evenness, is a key measure of biodiversity.

Working memory is central to our mental lives; we use it to add up the cost of our shopping or to remember the beginning of this sentence at its end. Some scientists argue it is particularly developed in humans, but how do chimpanzees, one of our closest relatives, compare? Researchers set out to answer this question: here.
Scientists have developed new artificial intelligence software to recognize and track the faces of individual chimpanzees in the wild. The new software will allow researchers and wildlife conservationists to significantly cut back on time and resources spent analyzing video footage, according to the new article: here.
Researchers report on the average life expectancy of chimpanzees in Japan. The average life expectancy of chimpanzees who reach adulthood — reported as 12-years-old in the paper — is 40 years: 41.5 years for males and 39.2 years for females: here.
