Sleep-wake rhythm: Fish change our understanding of sleep regulation      (via sciencedaily.com)     Original source 

Researchers have discovered that some fish -- unlike humans -- do not need orexin to stay awake. This molecule was thought to be necessary for normal wake and sleep rhythms in vertebrates. Humans without orexin suffer from narcolepsy.

Chimp moms play with their offspring through good times and bad      (via sciencedaily.com)     Original source 

A recent study observing wild chimpanzees over a period of more than 10 years revealed that when food gets scarcer, the adults put play aside and focus on survival, while mother chimps continue to be their children's primary playmate -- suggesting their indispensable role to foster their young's physical and social development.

Unique way to track carbon emissions in bodies of water      (via sciencedaily.com)     Original source 

Carbon dioxide emissions are not typically associated with water ways, like streams and rivers, but emerging research shows that water bodies play an important role in storing and releasing carbon dioxide. As many states look for cost-effective ways to mitigate climate change, scientists looked at a way to optimize CO2 sensors to better measure carbon dioxide emissions in lotic, or moving, bodies of water offering a new tool that can help provide valuable information for everything from land use to climate action plans.

Marine heat waves disrupt the ocean food web in the northeast Pacific Ocean      (via sciencedaily.com)     Original source 

Marine heat waves in the northeast Pacific Ocean create ongoing and complex disruptions of the ocean food web that may benefit some species but threaten the future of many others, a new study has shown.

Drought, soil desiccation cracking, and carbon dioxide emissions: an overlooked feedback loop exacerbating climate change      (via sciencedaily.com)     Original source 

Soil stores 80 percent of carbon on earth, yet with increasing cycles of drought, that crucial reservoir is cracking and breaking down, releasing even more greenhouse gases creating an amplified feedback loop that could accelerate climate change.

Sonic youth: Healthy reef sounds increase coral settlement      (via sciencedaily.com)     Original source 

Healthy coral reefs have rich soundscapes, full of the croaks, purrs, and grunts of various fishes and the crackling of snapping shrimp. Larval coral uses these sounds as cues to identify the best places to settle and grow. The authors found that sound could potentially be a vital tool in the effort to restore coral reefs. Broadcasting the sounds of a healthy reef to a reef that is degraded encourages coral larvae to settle there. This indicates that it's possible that 'acoustic enrichment' can be a key intervention to support imperiled reefs.

New study shows how AI can help us better understand global threats to wildlife      (via sciencedaily.com)     Original source 

Researchers used AI to scour information from websites and social media to map bat hunting and trade. Research found evidence of bat exploitation in 22 countries that had not previously been identified by traditional academic research. Following concerns about the reliability of the IUCN Red List, new research demonstrates how AI's ability to filter vast amounts of online data can support wildlife conservation.

Summer solstice triggers synchronized beech tree reproduction across Europe      (via sciencedaily.com)     Original source 

A new study has found that the summer solstice acts as a 'starting gun' to synchronize beech tree reproduction across vast distances in Europe, affecting ecosystem functions.

Who knew that coprophagy was so vital for birds' survival?      (via sciencedaily.com)     Original source 

New research explains how eating feces (known as coprophagy) shapes wild birds' digestive tracts (gut biota), enabling them to absorb lost or deficient nutrients and adjust to seasonal variations in food sources.

Giant sequoias are a rapidly growing feature of the UK landscape      (via sciencedaily.com)     Original source 

Imported giant sequoia trees are well adapted to the UK, growing at rates close to their native ranges and capturing large amounts of carbon during their long lives, finds a new study.

Exploring arctic plants and lichens: An important conservation baseline for Nunavut's newest and largest territorial park      (via sciencedaily.com)     Original source 

A comprehensive study of the floristic diversity of Agguttinni Territorial Park, Nunavut's newest and largest Territorial Park, has documented 141 vascular plant, 69 bryophyte, and 93 lichen species from this unique protected area on northern Baffin Island. Through a combination of extensive fieldwork in 2021 and examination of hundreds of existing herbarium specimens, the authors have documented species newly reported for Baffin Island and have crafted a biodiversity baseline important for park management and conservation.

History repeats as Coral Bay faces mass loss of coral and fish life      (via sciencedaily.com)     Original source 

A perfect storm of environmental factors has seen a monumental loss of fish and coral life at a popular area of Ningaloo Reef in Western Australia's Gascoyne region -- however research into the event shows there is hope it will recover. In March 2022, during the annual coral spawning event, calm weather and limited tidal movement combined to trap the coral's eggs within Bills Bay, at the town of Coral Bay. This led to an excess of nutrients in the water which consumed more oxygen than usual -- causing massive numbers of fish and corals to die from asphyxiation.

A coral superhighway in the Indian Ocean      (via sciencedaily.com)     Original source 

Despite being scattered across more than a million square kilometers, new research has revealed that remote coral reefs across the Seychelles are closely related. Using genetic analyses and oceanographic modelling, researchers demonstrated for the first time that a network of ocean currents scatter significant numbers of larvae between these distant islands, acting as a 'coral superhighway.'

Rainforest's next generation of trees threatened 30 years after logging      (via sciencedaily.com)     Original source 

Rainforest seedlings are more likely to survive in natural forests than in places where logging has happened -- even if tree restoration projects have taken place, new research shows.

Gene flow in giraffes and what it means for their conservation      (via sciencedaily.com)     Original source 

Giraffes, with their bizarre body plan, have always held a special place in the minds of evolutionary biologists and non-experts alike. In a new study whole-genome sequencing data was used to investigate the evolutionary processes occurring within giraffes. In particular, the authors were interested in establishing whether different populations of giraffes really have been isolated from each other for extended periods of time, which is normally a requirement before new species can arise.
