A recent study found that coyote density in Seattle is 9 times higher than in wild areas, with urban coyotes benefiting from abundant food and reduced predation. Coyotes' diets are also more diverse in cities, with a wider variety of food options available, including berries and rabbits.
The RESINA project, launched by three Spanish universities, aims to identify and transfer sustainable ways of living from rural Spain. The project will document practices based on neighbourly cooperation, agroecology, and communal resource management, making them publicly available through an Open Methodological Toolkit.
A long-term study found that invasive Burmese pythons led to a dramatic decline in woodrat populations, while cotton mouse populations surged following Hurricane Irma's landfall. The study highlights the disproportionate impact of invasive predators on endemic ecosystem engineers and underscores the need for targeted conservation efforts.
A new study reveals that wildfires in the Western US have decreased by 28% over the past three decades, with fires starting from natural causes declining more than those caused by humans. The findings suggest that higher population densities lead to fewer fires, while adding people to less populated areas makes blazes more common.
A new study suggests that expanding seasonal immunization access could minimize off-season RSV epidemics, with higher rates of hospitalizations in urban areas compared to rural communities. Providing year-round access to RSV immunization would be more risk-averse and minimize risks of large seasonal outbreaks.
A new study reveals that land-use change was the primary cause of biodiversity loss on Mount Kilimanjaro's lower slopes over the last century. Human activities such as population growth and economic development led to a decline in plant species diversity, with up to 75% lost per square kilometer.
Researchers found that the caterpillars' cycles interact with natural controls like viral disease, and they're highly adapted to their environment. Outbreaks can be predicted and damage controlled, but the exact timing is linked to specific factors.
A Brazilian study estimated deer population density in the Atlantic Rainforest, revealing human pressures like hunting and livestock diseases significantly impact deer numbers. The research provides strong evidence for conservation management and protected area protection.
A new study reveals significant shifts in prehistoric hunter-gatherer populations in Europe due to climate changes at the end of the last Ice Age. The population declined by half, but some areas in central Europe showed stability or even an increase in population size, indicating human migration towards the east.
A study of over 97 citizen scientists found that coastal areas have significantly more litter than inland locations, with urban areas consistently exhibiting more litter than rural areas. The research highlights the need for tailored waste management strategies to address regional differences in litter patterns.
A Rice University study has found that rising temperatures exacerbate competition within populations, leading to population crashes. This research provides a critical link between temperature increases and declines in species populations, shedding new light on the threats posed by global warming.
Researchers studied pumice rafts from the 2021 Fukutoku-Oka-no-Ba eruption in Japan, finding three phases of evolution involving rounding, fragmentation, and biodiversity increase. The study provides valuable information for mitigating the impact of future eruptions on shoreline communities.
The studies, published in various journals, found that prey depletion has a significant impact on population dynamics of large African carnivores. In protected areas, lion populations have shown growth due to increased prey availability, while African wild dogs face challenges with low prey density and high competition from lions.
Researchers found that high human density areas were associated with longer coyote lifespans, contrary to expectations. In areas with low human density, coyotes from lower-income neighborhoods were more likely to survive than those from high-income areas.
The 'Our Way Model' reveals four phases of human dispersal, including a slow expansion from the Levant to western Europe and rapid advancements into previously unsettled areas. Climate change significantly impacted human dispersal, with periods of severe cold and warming influencing population growth and decline.
