Published Improved wildfire smoke model identifies areas for public health intervention
(via sciencedaily.com) Original source The Canadian wildfires of June 2023 exposed a large portion of the Northeastern United States to unprecedented levels of smoke. A new model that combines wildfire smoke forecasts and data from ground-based sensors may help public health officials plan targeted interventions in areas most at risk for the negative health effects of unexpected smoke events and air pollution, according to scientists.
Published New record holder for smallest dispersers of ingested seeds: Woodlice
(via sciencedaily.com) Original source Even bugs as small as woodlice can disperse seeds they eat, setting a new record for smallest animal recorded to do so. The discovery underscores the crucial yet often overlooked role that small invertebrates play in ecosystems.
Published Acceptance of animals in urban environments
(via sciencedaily.com) Original source How do city residents feel about animals in their immediate surroundings? A recent study shows how different the acceptance of various wild animals in urban areas is. Important factors are the places where the animals are found and their level of popularity -- squirrels and ladybugs come out on top here. The results have important implications for urban planning and nature conservation.
Published Chimps learn and improve tool-using skills even as adults, study finds
(via sciencedaily.com) Original source Chimpanzees continue to learn and hone their skills well into adulthood, a capacity that might be essential for the evolution of complex and varied tool use, according to a new study.
Published DDT pollutants found in deep sea fish off Los Angeles coast
(via sciencedaily.com) Original source As the region reckons with its toxic history of offshore dumping off the California coast, new findings raise troubling questions about whether the banned pesticide remains a threat to wildlife and human health.
Published In medieval England, leprosy spread between red squirrels and people, genome evidence shows
(via sciencedaily.com) Original source Evidence from archaeological sites in the medieval English city of Winchester shows that English red squirrels once served as an important host for Mycobacterium leprae strains that caused leprosy in people, researchers report.
Published Wildfires in wet African forests have doubled in recent decades
(via sciencedaily.com) Original source Climate change and human activities like deforestation are causing more fires in central and west Africa's wet, tropical forests, according to the first-ever comprehensive survey there. The fires have long been overlooked.
Published Artificial intelligence enhances monitoring of threatened marbled murrelet
(via sciencedaily.com) Original source Artificial intelligence analysis of data gathered by acoustic recording devices is a promising new tool for monitoring the marbled murrelet and other secretive, hard-to-study species.
Published Missing link in species conservation: Pharmacists, chemists could turn tide on plant, animal extinction
(via sciencedaily.com) Original source As the world faces the loss of a staggering number of species of animals and plants to endangerment and extinction, one scientist has an urgent message: Chemists and pharmacists should be key players in species conservation efforts.
Published Researchers parse oddity of distantly related bats in Solomon Islands that appear identical
(via sciencedaily.com) Original source A study of body size in leaf-nosed bats of the Solomon Islands has revealed surprising genetic diversity among nearly indistinguishable species on different islands.
Published Protecting endangered monkeys from poachers, habitat loss
(via sciencedaily.com) Original source The 17 species of red colobus monkey living across Africa, including in the Tai Project field station region, have been singled out by scientists as a priority conservation target. Protection of these monkeys, they assert, can be expected to produce benefits throughout tropical African forests where hunting and climate change have led to dramatic wildlife and habitat loss.
Published Fading lights: Multiple threats to North America's firefly populations
(via sciencedaily.com) Original source Scientists have applied a data-driven approach to understanding firefly population dynamics on a continental scale. Key findings from this new study indicate that fireflies, part of the beetle order, are sensitive to various environmental factors, from short-term weather conditions to longer climatic trends, including the number of growing-degree days related to temperature accumulations.
Published More plants on the menu of ancient hunter-gatherers
(via sciencedaily.com) Original source It has long been thought that meat played an important role in the diet of hunter-gatherers before the Neolithic transition. However, due to the scarcity of well-preserved human remains from Paleolithic sites, little information exists about the dietary habits of pre-agricultural human groups. A new study challenges this notion by presenting compelling isotopic evidence of a strong preference for plants among 15,000-year-old hunter-gatherers from Morocco. This is the first time a significant amount of plant consumption has been measured for a pre-agricultural population, shedding new light on the dietary practices of ancient human societies.
Published Florida dolphin found with highly pathogenic avian flu
(via sciencedaily.com) Original source Report details first-ever finding of highly pathogenic avian influenza virus in North American dolphin.
Published Anthropologist documents how women and shepherds historically reduced wildfire risk in Central Italy
(via sciencedaily.com) Original source Fire management lessons from the past could help to improve resilience as the Mediterranean faces increased fire risk from climate change. How traditional land management practices once greatly reduced fuel for wildfires, and how these practices were forgotten, in part due to historical politics of classism and sexism.
Published Curiosity promotes biodiversity
(via sciencedaily.com) Original source Cichlid fishes exhibit differing degrees of curiosity. The cause for this lies in their genes, as reported by researchers. This trait influences the cichlids' ability to adapt to new habitats.
Published Scientists replace fishmeal in aquaculture with microbial protein derived from soybean processing wastewater
(via sciencedaily.com) Original source Scientists have successfully replaced half of the fishmeal protein in the diets of farmed Asian seabass with a 'single cell protein' cultivated from microbes in soybean processing wastewater, paving the way for more sustainable fish farming practices.
Published Deer are expanding north, and that's not good for caribou
(via sciencedaily.com) Original source In the boreal forest of Western Canada, researchers have considered that both changing climate and increased habitat alteration have enabled deer to push farther north.
Published Unveiling the lionfish invasion in the Mediterranean Sea
(via sciencedaily.com) Original source Researchers have published a comprehensive study on the invasion of lionfish in the Mediterranean Sea, highlighting a rapid spread and the potential ecological impacts. The research shows the lionfish species Pterois miles has significantly expanded its territory in the Mediterranean since the invasion began around ten years ago. The invasive species has established presence in the eastern Mediterranean, with observations now extending to colder waters previously thought to be unsuitable for the species.
Published These giant, prehistoric salmon had tusk-like teeth
(via sciencedaily.com) Original source Oncorhynchus rastrosus, a giant species of salmon that lived in the North American Pacific Northwest a few million years ago, sported a pair of front teeth that projected out from the sides of its mouth like tusks, according to a new study.
