Scientists at American Geophysical Union conference present new findings on a resource becoming more precious than gold
How flowers have evolved particular colours, shapes and scents to attract pollinators has long fascinated ecologists. Now, using artificial flowers and high-speed video, researchers have gained intriguing insights into the intimate relationship between hummingbirds and the flowers they pollinate. The study, published in the British Ecological Society's journal Functional Ecology, is the first to measure how much energy hummingbirds use while hovering to feed from flowers of different orientation.
Nitrogen is a beneficial plant fertilizer in small amounts, but large amounts cause negative impacts on ecosystems, such as water pollution, acidification of soils, increased productivity of invasive species, increased probability of wildfire, and a decline of native plant diversity.
Curtin University research showing that bacteria were responsible for the excellent preservation of a crab-like fossil during the Devonian period suggests that organic geochemistry could be a useful new tool for understanding ancient environments.
The University of Haifa, Israel, has dedicated Israel's first research center for Green Roofs Ecology, which will focus on research and development of non-irrigated green roofs; improving biological diversity with green roofs; and developing ecological and evolutionary theories.
Moving animals for conservation is not a panacea. This is what Irene Pérez and colleagues from Arizona State University and several Spanish institutions have concluded after evaluating 280 published translocation projects worldwide and 107 unpublished Spanish projects.
Research at the University of Southampton is protecting fish that inhabit rivers and estuaries impacted by dams and power plants.
Leipzig. Researchers from Germany and Slovakia have pointed out that the chemical triclosan is one of those particularly harmful substances for the ecological status of rivers that are still not sufficiently monitored.
Plastic nanoparticles in oceans seem to have a damaging effect on sea life. Called as ‘plastic soup,’ this occurs when plastic debris entering the sea decomposes. Plastic nanoparticles also enter from washed clothes and from cosmetics.
A new study raises the question whether worship of nature is detrimental to the environment. The research conducted by Robin Canniford of the University of Melbourne and Avi Shankar of the University of Bath has been published in the Journal of Consumer Research.
