A study conducted by a UPV/EHU-University of the Basque Country research group within the framework of the European Globaqua project proposes going beyond the study of river ecosystems and incorporating into the studies routinely carried out a set of processes that regulate not only the fluxes of matter but also the fluxes of energy within an ecosystem. In a recently published paper, the group is proposing a new working framework to study the status of rivers.
The preferred fodder of horses is grass. This is true for domestic horses and wild horses in the Gobi Desert. Researchers from Vetmeduni Vienna found out through tail hair analysis that before their extinction in the wild Przewalski's horses had been on a different diet than today. Thanks to improved societal attitude, the horses have now access to richer pastures. In former times, the wild horses were hunted and chased away. Published in Scientific Reports.
University of South Florida biologists have found that a crucial window in the development of tadpoles may influence a frog's later ability to fight infectious diseases as an adult.
Climate change may be harming the future of African wild dogs (Lycaon pictus) by impacting the survival rates of pups, according to one of the first studies on how shifting temperatures are impacting tropical species. Led by scientists from ZSL (Zoological Society of London) and published in the Journal of Animal Ecology, the study highlights how African wild dogs -- already classified as Endangered by the IUCN Red List -- raise fewer pups at high temperatures.
The true scale of the problem facing world's most illegally traded mammal has been revealed.
A new global analysis of forest habitat loss and wildlife extinction risk published July 19 in the journal Nature shows that species most at risk live in areas just beginning to see the impacts of human activities such as hunting, mining, logging and ranching.
Bornean orangutans living in forests impacted by human commerce seek areas of denser canopy enclosure, taller trees, and sections with trees of uniform height, according to new research. These orangutans are critically endangered, and despite intense conservation efforts, their numbers continue to decline. Additional habitat management strategies that account for their presence in forests affected by logging and other human activity are needed to ensure the species' survival.
A Kansas State University study has found that male and female live-bearing fish evolve differently: female evolution is influenced more strongly by natural selection, while male evolution is influenced more strongly by sexual selection.
Climate change leads to loss of biodiversity worldwide. However, ecosystems with a higher biodiversity in the first place might be less affected a new study in Science Advances reports. An international research team found that when they experimentally warmed meadows, the diversity of nematode worms living in the soil went down in monocultures, whereas the opposite was true for meadows with many different herbaceous plant species.
Chronic obstructive pulmonary disease (COPD) can result in structural changes within the lungs over time. Scientists at the Helmholtz Zentrum München have now been able to show that these changes not only affect the organ itself, but also the bacteria that live in the lung. The results have been published in PLOS ONE.
