Tourist photographs provide reliable and important wildlife monitoring data.⁠
⁠
A new study published by Cell Press has demonstrated that images captured by tourists on safari contain valuable wildlife monitoring data. Using 25,000 photographs from 26 tour groups, the researchers analyzed the population densities of lions, leopards, cheetahs, spotted hyenas, and wild dogs in northern Botswana.⁠
⁠
Study lead author Kasim Rafiq came up with the idea of utilizing tourist photographic data one day when his vehicle got stuck in an abandoned warthog burrow while he was following a set of leopard tracks. At the time, Rafiq was a Ph.D. candidate at Liverpool John Moores University and had been searching for months for a one-eared leopard named Pavarotti.⁠
⁠
“Eventually I got out of the hole and spoke with the safari guides who I met on the road nearby, and who were laughing,” said Rafiq. “They told me that they’d seen Pavarotti earlier that morning. At that point, I really began to appreciate the volume of information that the guides and tourists were collecting and how it was being lost.”⁠
⁠
Wildlife population monitoring in Africa is traditionally done using either camera traps, track surveys, or call-in stations. Each of these methods has its advantages and disadvantages. For example, camera traps are particularly useful for observing various species in the wild, but they are very expensive with no guaranteed lifespan. ⁠

New model will help experts protect endangered blue whales.⁠
⁠
Scientists at the Oregon State University Marine Mammal Institute have used a statistical model to predict the feeding behavior of blue whales in the California Current Ecosystem. The research will provide new insight that could help protect the endangered blue whales.⁠
⁠
The model used by the team combines long-term satellite tracking of the population’s movements with environmental data such as ocean temperatures. This gives experts a larger ecosystem view to help them understand how threats such as climate change and ship strikes may affect the whales over time. ⁠
⁠
“Most management decisions up to now have been based on locations where the whales tend to be found,” said study lead author Daniel Palacios. “But it’s not just where the whales are, but also the activity – are they actually eating there or simply moving through – that matters. This model can tell us which areas are the most important for actual foraging.”⁠
⁠
Blue whales grow up to 90 feet in length and weigh up to 300,000 pounds, yet they feed primarily on tiny shrimp-like krill that are less than two inches long. It is estimated that 1,600 of the world’s 10,000 blue whales, known as the North Pacific population, spend the summer and fall off the western coast of the United States. ⁠
⁠
The California Current Ecosystem stretches from Baja California up to the Canadian border. Along this stretch, steady winds in the spring and summer seasons promote a rich and productive marine community. The study was focused on the relationship between the whales’ feeding behavior and the ocean conditions during the feeding season in this particular region. ⁠

Are Tigers Endangered? What Does Endangered Even Mean?⁠
Tigers are among the most charismatic creatures that roam our Earth. They are popular school and sports mascots. They are the namesake for fish, types of stones, birds and various insects. No matter how you cut it, tigers are a species of legendary recognition around the world. How is this culturally and naturally important creature doing in the 21st century? Are tigers endangered? ⁠
⁠
To answer this, we must first define the term ‘endangered.’⁠
What Does Being ‘Endangered’ Mean?⁠
The term ‘Endangered Species’ is a relatively recent term. It was first used in the late 1950’s or early 1960’s. The most simple definition of the term is ‘a species at risk of extinction.’ Various groups can designate a plant or animal as an endangered species. The United States federal government is perhaps the most well-known entity. They use the Endangered Species Act to designate protections. State governments also have the ability to pronounce an endangered species within their state.⁠
⁠
The International Union for the Conservation of Nature (IUCN) is the most prominent authority for listing species internationally. The IUCN Red List is the definitive guide to the conservation status of species globally.⁠
⁠
The conservation status of a species is broken into categories. The most common species are of ‘Least Concern.’ These are species like crows and dandelions. ‘Threatened’ species are at risk of extinction, ‘Endangered Species’ are at a high risk of extinction, and ‘Critically Endangered’ species are on the brink of extinction. The IUCN has reviewed nearly 100,000 species, and determined that about 27,000 of these are ‘Threatened’, ‘Endangered’, or ‘Critically Endangered.’ ⁠

Endangered Bornean orangutan numbers drop near oil palm plantations.⁠
⁠
Orangutans can be widely considered one of the most recognizable faces of animal conservation efforts around the world, as these intelligent great apes are one of the most captivating endangered species.⁠
⁠
Efforts to preserve the species have faced numerous challenges in recent years due to habitat loss and poaching, and a new study published in PLOS ONE gives a closer look at just how these conservation efforts are going.⁠
⁠
Led by Donna Simon of the World Wide Fund for Nature and colleagues, a recent series of surveys of the population of endangered Bornean orangutans in Sabah – the Malaysian state in the north-east of Borneo – have found mixed results. While the species’ populations within the well-managed forests are stable, they have declined in areas near major oil palm plantations. ⁠
⁠
In Sabah, the lowland forest is the most crucial habitat for orangutans. But in the last half-century, extensive logging and land clearance for agriculture have results in habitat loss and fragmentation, leading to a significant decline in the species’ population. Despite these declines, the full story of the effects this activity is having on the orangutans is still not well known.⁠

Artificial snow could help stabilize the West Antarctic Ice Sheet.⁠
⁠
Climate engineering has been gaining traction in recent years with proposals ranging from creating artificial rain to spraying aerosols in the atmosphere that will help cool the planet.⁠
⁠
But these “planet hacking” methods are also viewed as extreme and are not without their risks and high economic costs. ⁠
⁠
As impacts of climate change become more severe, high-risk, high-cost geoengineering may outweigh the projected socio-economic and environmental costs of rising sea levels. ⁠
⁠
A new study published in the journal Science Advances details an extreme but potentially successful solution that could help stabilize the West Antarctic ice sheet. ⁠
⁠
If the West Antarctic ice sheet melts, projections estimate that it could raise sea levels by nearly ten feet, enough to cause significant damage and displace populations in New York, Calcutta, Shanghai, and Tokyo. ⁠
⁠
The ice sheet is already melting, and in this new study, a potential solution to stop it would be to cover the area in artificial snow. ⁠
⁠
Pumping ocean water onto the coastal areas of the region and converting the water into snow could help stabilize the ice sheet. While the solution is doable and not as risky as other potential stabilizing proposals, the researchers of the study warn that it would be incredibly costly. ⁠

Sharks might have been used to make your household products.⁠
⁠
As the movement towards organic products grows, more and more people are becoming aware of the ingredients in favorite household products. Yet most people likely have no clue that sharks may have been used to make these products. ⁠
⁠
Shark populations have plummeted due to the insatiable demand for shark products. An estimated 100 million sharks are fished every year from our oceans. ⁠
⁠
Sharks are especially vulnerable to overexploitation due to their late maturation and low reproduction rates. The IUCN Shark Specialist Group found that sharks, rays and chimaeras have the lowest percentage of species considered safe when compared to other animal groups. A quarter of shark and ray species are currently threatened with extinction.⁠
⁠
While shark finning for shark fin soup appears to be the major driver of population declines, the use of sharks for household products is an often-overlooked factor.⁠
⁠
Sharks are used for a wide range of products, from cosmetics to pet food to garden fertilizer, according Shark Water.⁠
⁠
Multiple parts of the shark are utilized for household products, such as shark skin for leather and shark cartilage for dietary supplements and alternative medicine. Sharks are even exploited for an oil they produce in their liver which is used in cosmetic and health products.⁠

Historic wildlife bust highlights how the black market threatens ecosystems.⁠
⁠
When we think of the impact of industry on the environment, we tend to think of legal industry. The impact of pollution from mining, deforestation from logging or farming, and overfishing may all come to mind. Unfortunately, illegal industry that is beyond the realm of normal governmental regulation has an impact on wildlife populations and the environment as well. ⁠
⁠
According to the US Fish & Wildlife Service, the trade of illegal wildlife is thought to be a multi-billion dollar business. Many animals have been used to highlight the dangers of this illegal trade and promote tougher laws and regulations. Rhinoceros, elephants, even the lesser known but more interesting pangolin are widely known to be harmed by the illegal trade in animal parts. ⁠
⁠
Less often considered but no less detrimental to wild ecosystems is the illegal trade in exotic pets. As we’ve reported, exotic pets can be dangerous and harmful to animal populations and local ecosystems. In Latin America, Smithsonian reports that biologists have found as much as 30% of parrot nests raided for the pet trade. I’ve been disappointed while volunteering in parrot conservation work in the Bahamas to find nest cavities cleared of parrot chicks overnight. ⁠

Nitrogen runoff is also killing coral reefs.⁠
⁠
Coral reefs are dying off at an alarming rate with mass bleaching events becoming more and more common. ⁠
⁠
While many studies have rightly attributed the cause of these bleachings to climate change, increasing ocean temperatures, and ocean acidification, a new study has discovered another root cause of the world’s coral catastrophe. ⁠
⁠
After reviewing 30 years of unique data from the Lower Florida Keys, researchers from the Harbor Branch Oceanographic Institute at Florida Atlantic University found that increases in nitrogen levels are starving out corals and making them susceptible to bleaching.⁠
⁠
“Citing climate change as the exclusive cause of coral reef demise worldwide misses the critical point that water quality plays a role, too,” said James W. Porter, a co-author of the study. “While there is little that communities living near coral reefs can do to stop global warming, there is a lot they can do to reduce nitrogen runoff. Our study shows that the fight to preserve coral reefs requires local, not just global, action.”⁠
⁠
Nutrient runoff from fertilizers, topsoil, and improperly treated sewage are adding nitrogen to the environment. This added nitrogen has led to phosphorus starvation in corals which lowers the coral’s threshold for bleaching. ⁠

UN expert: Better infrastructure needed to sustain climate change extremes.⁠
⁠
While you’re likely to hear about the more significant natural disasters that occur around the world, the smaller-scale catastrophes are less likely to make the news cycle – yet, scientists believe that climate change is resulting in these natural disasters happening nearly every week. ⁠
⁠
Cyclones, heatwaves, droughts, and other natural phenomena have been occurring at a rapid rate across many regions of the world. In many of these areas, developing countries are not prepared to deal with the fallout. ⁠
⁠
United Nations (UN) disaster expert Mami Mizutori told The Guardian that more emphasis needs to be placed on investments into resilient infrastructure, along with emission cuts. Mizutori believes the focus should be on nature-based solutions to addressing climate hazards, such as protecting the growth of mangrove swamps and wetlands to limit flooding.⁠
⁠
The UN warns that while tropical cyclones such as Idai and Kenneth have been largely covered by the news, smaller “lower impact events” are happening at a higher rate and many are not being covered in the headlines. ⁠

Antarctic ice instability could accelerate sea level rise.⁠
⁠
Antarctica has the potential to contribute far more to sea level rise than the Arctic.⁠
⁠
In the last six years alone, the rate of ice loss for five major glaciers in the South Pole has doubled. Now, a new study has found this rate will continue to accelerate and drive up sea level rise even faster than previously predicted due to glacier instability.⁠
⁠
Researchers from the Georgia Institute of Technology, NASA’s Jet Propulsion Laboratory, and the University of Washington factored in instability into different ice flow simulations to model future sea level rise contributions from Antarctica.⁠
⁠
It all boils down to triggering instability and speeding up glacial ice flow into the ocean, which will increase sea level rise. ⁠
⁠
Unfortunately, projecting this tipping point and coming with an accurate timeline is impossible due to variability and unpredictable fluctuations that impede consistent data collection in Antarctica.⁠
⁠
The researchers included instability into 500 ice flow simulations for the Thwaites Glacier. ⁠
⁠
Using math from statistical physics, the researchers were able to calculate how random variables like temperature changes will impact ice flow predictability.⁠
⁠
Each end scenario result differed drastically from the other, but each pointed to an eventual tipping point, triggering instability and speeding up ice flow into the ocean.⁠

Scientists may have discovered the oldest relative of the great white shark.⁠
⁠
Researchers led by Patrick L. Jambura at the University of Vienna have traced back the origin of mackerel sharks to a small benthic shark from the Middle Jurassic that lived 165 million years ago. ⁠
⁠
The investigation was based on the discovery of a unique feature in the tooth composition of mackerels, a group which includes the infamous great white shark and Megalodon, the biggest predatory shark of all time. ⁠
⁠
Shark teeth are similar to human teeth because they are composed of two mineralized structures, including a hard shell like enamel and two types of dentine core. Osteodentine, which resembles real bone, can be found in the root, while orthodentine is very compact and is confined to the tooth crown.⁠
⁠
The researchers used high resolution CT scans to examine the tooth composition of the great white shark and its relatives. They were surprised to find that the osteodentine of the roots intruded into the crown and replaced the orthodentine completely. This condition is not known from any other shark.⁠

Common butterfly species on the decline, decades-long study reveals.⁠
⁠
A decades-long program monitoring the butterfly abundance in Ohio has shown that the general abundance of butterflies in the region has declined 33% in the past 21 years.⁠
⁠
Although the study was limited to one geographic area and one group of butterflies, the findings show the broader effects of climate change and other human-caused disturbances on insect populations.⁠
⁠
This study is published in PLOS ONE.⁠
⁠
“These declines in abundance are happening in common species,” said study leader Tyson Wepprich, an Oregon State University researcher. “Declines in common species concern me because it shows that there are widespread environmental causes for the declines affecting species we thought were well adapted to share a landscape with humans. Common species are also the ones that contribute the bulk of the pollination or bird food to the ecosystem, so their slow, consistent decline is likely having ripple effects beyond butterfly numbers.”⁠
⁠
Wepprich used more than 24,000 butterfly surveys from trained citizen scientists in Ohio, completed between 1996 and 2016, to come to his conclusion. The data collected was then used to estimate population trends for 81 butterfly species.⁠
⁠
“Because it’s easier to monitor butterflies than other insects — lots of people like butterflies and enjoy keeping track of them — butterflies tend to be the best source of abundance data for tracking insect population declines and increases,” Wepprich said. “Environmental assessments use them as an indicator for the general trajectory of biodiversity since they experience the same types of pressures from land-use changes, climate change and habitat degradation as other insect groups.”⁠

The moves of a dancing cockatoo are coordinated and not random⁠

A new analysis of the dancing cockatoo named Snowball has revealed that the bird responds to music with diverse and coordinated movements. The research suggests that this is not a random response to music, but one that emerges from certain cognitive and neural capacities in the animal brain.⁠

Study senior author Aniruddh Patel is a psychologist at Tufts University and Harvard University. “What’s most interesting to us is the sheer diversity of his movements to music,” said Patel, noting that Snowball developed the moves without any training.⁠
⁠
A previous study by Patel confirmed that Snowball could move to the beat, an ability that comes naturally to humans but not to other primates. Irena Schulz, Snowball’s owner and an author on the new paper, soon noticed that Snowball was making movements to music that had not been seen before.⁠
⁠
This prompted researchers to explore a similarity between Snowball’s dancing and human dancing found in the diversity of his movements and the body parts he uses in response to music. ⁠
⁠
Patel’s team filmed Snowball as he danced to two classic hits of the eighties: “Another One Bites the Dust” and “Girls Just Want to Have Fun.” The songs were each played for Snowball three times.⁠

Right whales have been recorded singing for the first time.⁠
⁠
Right whales have large, distinctive heads that can help identify them and also hold baleen to filter tiny food such as plankton from the ocean. They are impressive animals, weighing as much as 100 tons and living at least 70-year life spans. The only way these whales are obscured is by living in remote, wild and open parts of the ocean much more massive than even they are. Still, whales have played an important role in culture and unfortunately have tangled in human economics. ⁠
⁠
The right whale in particular has a long relationship with humans, especially from being hunted. Indeed, even the name ‘right whale’ was given to the unfortunate mammal by whalers who dubbed it the ‘right whale’ to kill, according to National Geographic. The whales were viable prey for whalers because they swim slowly and float after death. ⁠
⁠
Despite international law, the USSR and Russia hunted North Pacific right whales from 1965 to 1999, a time when only 82 of the whale sightings were reported in the eastern portion of the North Pacific. Due largely to whaling, right whales have been on the Endangered Species List since 1970, according to NOAA. Historically, the whales were found throughout oceans from temperate waters to the subpolar Bering Sea. Today, with a population much reduced, knowing the full extent of the North Pacific right whale’s range is complicated by the smaller chance of seeing the whale anywhere. ⁠
⁠
Including the North Pacific right whale, there are three right whale species, left in minuscule numbers from the damage of whaling.⁠
