Collaboration between government and startups could help meet the climate challenge while growing small businesses. Findings could inform discussions on Green New Deal or any 'forward-looking policy package', say researchers.
A new study is using observations made by Henry David Thoreau -- 19th-century American naturalist, social reformer, and philosopher -- to explore the effects of climate change on tree leaf-out and, as a result, the emergence of spring wildflowers.
Scientists have asked, 'What is the primary driver in tropical forest diversity-competition for resources, or herbivore pests?' For the first time, University of Utah biologists compared the two mechanisms in a single study. The team analyzed how neighboring trees influence the growth and survival of nine coexisting species of the tree genus Inga in the Panama rainforest. They found that pests and the plant defenses against them drive diversity in tropical rainforests.
'Great Dying' extinction survivors appear to have shared many of the same ecological roles as their predecessors, with one catch -- there was a surge in the number of individuals with more modern traits. These hardy stand-outs did a better job of driving recovery, making ongoing ecological interactions more intense. Insights into this ancient marine system and its occupants can help guide modern conservation in identifying Earth's most resilient species in the face of environmental stress.
Climate change could contribute to the demographic collapse of the painted turtle, a species that has temperature-dependent sex determination. An Iowa State University scientist is sounding the alarm about the painted turtle's future in a new study.
Trust, transparency, communication, and fairness in the planning and management of conservation projects may be more important for gaining long-term local support than emphasizing ecological effectiveness, UBC-led research has discovered.
More than a quarter of the species in their dataset showed seasonal interest. For these seasonal species, the researchers found that the timing and amount of internet activity is a highly accurate measure of when and how the species is present. The team thinks it might be possible to measure changes in the presence and abundance of species simply by measuring internet activity.
Climate change is often talked about in terms of averages, like the goal set by the Paris Agreement to limit the Earth's temperature increase to 2 degrees Celsius. What such numbers fail to convey is that climate change will not only increase the world's average temperature, it will also intensify extreme heat waves that even now are causing harm. A recent review paper describes the potential impacts of these worsening events on people and wildlife.
New University of Montana research suggests climate change makes it increasingly difficult for tree seedlings to regenerate following wildfires in low-elevation forests, which could contribute to abrupt forest loss.
Anthropologists have long made the case that tool-making is one of the key behaviors that separated our human ancestors from other primates. A new paper, however, argues that it was not tool-making that set hominins apart -- it was the miniaturization of tools.
