Street Lights Affect Delicate Ecosystems
2012-05-24 04:26:42

Brett Smith for RedOrbit.com Civilization has long been derided for intruding upon the habitats of wild animals, and even man´s smaller neighbors have been affected by the wheels of progress. Another measure of this impact can be seen in how street lighting is having a transformative effect on communities of insects and other invertebrates living near them, according to researchers at the University of Exeter in the United Kingdom. A report published in Biology Letters showed...

Fragile Land-sea Ecological Chain Documented
2012-05-18 13:06:44

Douglas McCauley and Paul DeSalles did not set out to discover one of the longest ecological interaction chains ever documented. But that's exactly what they and a team of researchers — all current or former Stanford students and faculty — did in a new study published in Scientific Reports. Their findings shed light on how human disturbance of the natural world may lead to widespread, yet largely invisible, disruptions of ecological interaction chains. This, in turn, highlights...

Findings show need to reevaluate fungicide safety, researchers say Chlorothalonil, one of the world's most common fungicides used pervasively on food crops and golf courses, was lethal to a wide variety of freshwater organisms in a new study, University of South Florida researchers said Wednesday. Biologists Taegan McMahon and Jason Rohr, co-authors of the study published in the journal Ecology Letters, report that chlorothalonil killed amphibians, snails, zooplankton, algae, and...

From getting hands on with salt-tolerant samphire plants, to a lecture on 3D plant imaging and a tour of a permaculture garden, the activities for Fascination of Plants Day will give Australians a new insight into plants. In the two weeks around 18 May, Australian plant scientists from around the country are organizing events that showcase why plants are fascinating. Fascination of Plants Day is a worldwide event with 39 countries planning celebrations. The day is being organized by the...

Plant Diversity Key To Maintaining Productive Vegetation
2012-05-04 04:01:35

Long-term study finds that each species plays a role in maintaining a productive ecosystem Vegetation, such as a patch of prairie or a forest stand, is more productive in the long run when more plant species are present, results of a new study show. The long-term study of plant biodiversity found that each species plays a role in maintaining a productive ecosystem, especially when a long time horizon is considered. The research found that every additional species in a plot...

Cod Has A Key Role In The Whole Baltic Sea
2012-04-18 10:48:24

A new investigation put in evidence the key role of cod as regulator of the whole Baltic Sea ecosystem. The study shows that when the cod population in the central Baltic increases, it spreads into larger areas and spills over into adjacent marginal systems where it usually does not occur, as for example the Gulf of Riga. On the other hand, when the cod population size in the central Baltic decreases, it concentrates into the southern Baltic Sea and disappears from the other systems where...

Extreme weather such as hurricanes, torrential downpours and droughts will become more frequent in pace with global warming. Consequently, this increases the risk for species extinction, especially in bio diverse ecosystems such as coral reefs and tropical rainforests. Human impact means that flora and fauna become extinct at a rate 100-1000 times higher than normal. Climate change has been deemed as one of the main causes of species depletion. A research team in theoretical biology at...

Paris-based DIVERSITAS to spearhead global investigation into the '5 Ws' of biodiversity loss and how to mitigate it Concluding a four-year global consultation, international experts have agreed on key efforts needed to reduce the on-going loss of biodiversity and associated ecosystem services. On Day 2 of the Planet under Pressure conference in London (planetunderpressure2012.net) March 27, leaders of the global biodiversity research programme DIVERSITAS described the urgent need to...

Microorganisms play pivotal functions in nature, particularly within aquatic ecosystems. Whether in an ocean or a lake, they are key players in the food chain and the vitality of individual ecosystems. A team of researchers led by Arezoo M. Ardekani, the Rev. John Cardinal O'Hara, C.S.C., Assistant Professor of Aerospace and Mechanical Engineering at the University of Notre Dame, has shown that density stratification, a frequent feature of aquatic environments, has important ecological...

Image 1 - Past Disturbances Obscure Warming Impacts On Forests
2012-03-05 10:46:29

Past disturbances, such as logging, can obscure the effects of climate change on forest ecosystems. So reports a study just published in the Proceedings of the National Academy of Sciences. The paper, exploring nitrogen dynamics, found that untangling climate impacts from other factors can be difficult, even when scientists have access to decades of data on a forest's environmental conditions. Co-author Dr. Gene E. Likens of the Cary Institute comments, "Understanding how climate change is...

Rainforests
2013-04-19 19:33:20

Rainforests are forests that are characterized by high levels of rainfall, with definitions based on a minimum usual annual rainfall of about 68 to 78 inches. The monsoon trough, or otherwise known as the intertropical convergence zone, holds an important role in producing the climatic conditions that are essential for the Earth’s tropical rainforests. About 40 to 75 percent of all biotic species are native to the rainforests. It’s been estimated that there might be many millions of...

Taiga
2013-04-19 18:21:46

Taiga, or otherwise known as boreal forest, is a biome that is characterized by coniferous forests made up mostly of spruces, larches, and pines. The taiga is the world’s largest terrestrial biome. In North America, it covers most of inland Canada and Alaska as well as portions of the extreme northern continental United States and is known as the Northwoods. It covers most of Sweden, Finland, much of Norway, lowland/coastal areas of Iceland, much of Russia, northern Kazakhstan, northern...

Environmental Science
2014-01-12 00:00:00

Environmental science is a science that contains a wide range of scientific disciplines. These disciplines are grouped together based on the natural environment which they encompass and interact with. These sciences include physical, chemical, and biological components. Environmental science provides an interdisciplinary approach to the study of the environmental systems. The most common way environmental science is studied is through the work of one individual or small team drawing on the...

call-note
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
