Nine new snail species discovered in Papua New Guinea, a biodiversity hot spot at risk      (via sciencedaily.com)     Original source 

A new study describes nine new species of carnivorous land snails, all of which are so small they could fit together on a U.S. nickel. They present a rare opportunity to study a group that in many other places is disappearing fast. Worldwide, mollusks account for more than 50% of all recorded extinctions since the year 1500, and many of these were land snails from Pacific islands.

Scientists outline a bold solution to climate change, biodiversity loss, social injustice      (via sciencedaily.com)     Original source 

An international team of scientists has used a novel 500-year dataset to frame a 'restorative' pathway through which humanity can avoid the worst ecological and social outcomes of climate change.

Use of habitat for agricultural purposes puts primate infants at risk      (via sciencedaily.com)     Original source 

Frequent visits to oil palm plantations are leading to a sharp increase in mortality rates among infant southern pig-tailed macaques (Macaca nemestrina) in the wild, according to a new study. In addition to increased risk from predators and human encounters, exposure to harmful agricultural chemicals in this environment may negatively affect infant development.

Protected areas for elephants work best if they are connected      (via sciencedaily.com)     Original source 

The largest analysis yet of African savannah elephant populations shows that conservationists have successfully protected elephants in southern Africa for the last 25 years. However, the pattern varies regionally, with some elephant populations soaring and others still facing large declines. The key to long-term stability appears to be connecting large core areas with neighboring buffer zones, as opposed to well-protected but isolated protected areas known as 'fortress conservation.'

Monitoring the well-being of reservoir water through an uncrewed surface vehicle      (via sciencedaily.com)     Original source 

In a recent tragic incident, approximately 100 elephants in Africa perished due to inadequate access to water. The United Nations Environment Programme (UNEP) issues a warning that around 2.5 billion people worldwide could face water scarcity by 2025. In the face of water shortages affecting not only human society but also the entire ecological community due to the climate crisis, it becomes crucial to adopt comprehensive measures for managing water quality and quantity to avert such pressing challenges.

Researchers rely on Earth's magnetic field to verify an event mentioned in the Old Testament      (via sciencedaily.com)     Original source 

A new study scientifically corroborates an event described in the Second Book of Kings -- the conquest of the Philistine city of Gath by Hazael King of Aram. The method is based on measuring the magnetic field recorded in burnt bricks. The researchers say that the findings are important for determining the intensity of the fire and the scope of destruction in Gath, and also for understanding construction practices in the region.

Five new species of soft-furred hedgehogs from Southeast Asia      (via sciencedaily.com)     Original source 

A new study identifies five new species of soft-furred hedgehogs from Southeast Asia. The study used DNA analysis and physical characteristics to describe two entirely new species of soft-furred hedgehogs and elevate three subspecies to the level of species.

How national policies affect forests in border regions      (via sciencedaily.com)     Original source 

How do national policies impact deforestation? Researchers have looked into this question at the global scale and have found that, contrary to common assumptions, national strategies have a significant -- and visible -- influence on efforts to protect forest heritage.

First high mountain settlers at the start of the Neolithic already engaged in other livestock activities apart from transhumance      (via sciencedaily.com)     Original source 

An archaeological find in the Huescan Pyrenees allowed researchers to identify for the first time livestock management strategies and feeding practices which demonstrate how the first high mountain societies, at the start of the Neolithic period, were already carrying out complex livestock and farming activities, instead of being limited to the transhumance of sheep and goats.

Tree plantations can get better with age -- but original habitats are best      (via sciencedaily.com)     Original source 

Older tree plantations can be more attractive to animals who are looking for a new home than younger plantations, according to a new study. In the tropics, older plantations also welcome a greater variety of different plants and animals -- though sadly, Christmas tree plantations do not become more biodiverse over time.

Rise of archery in Andes Mountains dated to 5,000 years ago -- earlier than previous research      (via sciencedaily.com)     Original source 

Focusing on the Lake Titicaca Basin in the Andes mountains, anthropologists found through analysis of 1,179 projectile points that the rise of archery technology dates to around 5,000 years ago. Previous research held that archery in the Andes emerged around 3,000 years ago. The new research from UC Davis indicates that the adoption of bow-and-arrow technology coincided with both the expansion of exchange networks and the growing tendency for people to reside in villages.

World's smallest 'fanged' frogs found in Indonesia      (via sciencedaily.com)     Original source 

Researchers have identified a species of frog new to science. The Indonesian amphibian is the size of a quarter, unlike its two-pound cousins, and has tiny fangs. Nearly uniquely among amphibians, they lay their eggs on the leaves of trees, and the males guard and tend to the nests.

15 most pressing issues for conservation, including invertebrate decline and changing marine ecosystems      (via sciencedaily.com)     Original source 

Since 2009, the Cambridge Conservation Initiative has coordinated an annual horizon scan, a well-established method for predicting which threats, changes, and technologies will have the biggest impact on biological conservation in the following year. This year, the 15th horizon scan included 31 scientists, practitioners, and policymakers who developed a list of 96 issues, which they eventually narrowed down to the fifteen most novel and impactful. Their findings include topics related to sustainable energy, declining invertebrate populations, and changing marine ecosystems.
