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.

Soft robotic, wearable device improves walking for individual with Parkinson's disease      (via sciencedaily.com)     Original source 

Researchers have used a soft, wearable robot to help a person living with Parkinson's walk without freezing. The robotic garment, worn around the hips and thighs, gives a gentle push to the hips as the leg swings, helping the patient achieve a longer stride. The device completely eliminated the participant's freezing while walking indoors, allowing them to walk faster and further than they could without the garment's help.

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.

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.

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.

AI's memory-forming mechanism found to be strikingly similar to that of the brain      (via sciencedaily.com)     Original source 

An interdisciplinary team consisting of researchers has revealed a striking similarity between the memory processing of artificial intelligence (AI) models and the hippocampus of the human brain. This new finding provides a novel perspective on memory consolidation, which is a process that transforms short-term memories into long-term ones, in AI systems.

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.

How forests smell -- a risk for the climate?      (via sciencedaily.com)     Original source 

Plants emit odors for a variety of reasons, such as to communicate with each other, to deter herbivores or to respond to changing environmental conditions. An interdisciplinary team of researchers carried out a study to investigate how biodiversity influences the emission of these substances. For the first time, they were able to show that species-rich forests emit less of these gases into the atmosphere than monocultures. It was previously assumed that species-rich forests release more emissions. The Leipzig team has now been able to disprove this assumption experimentally.
