As trees grow larger in even-aged stands, competition develops among them.
New research has found that the number of pests and disease outbreaks in trees and forests across the world has been increasing.
A team of researchers from the University of Maryland, Google and the US government has put together the first comprehensive, high-resolution map of changes in global forest cover over the last 12 years.
Marine Biological Laboratory The vast sagebrush landscapes of the western United States are one of the largest ecosystems in North America. Long, cold winters and hot, dry summers characterize these cold desert ecosystems and create bone-dry soils during seasonal droughts. New research published this week from MBL (Marine Biological Laboratory) senior scientist Zoe Cardon, John Stark (Utah State University), and their two former students, sheds light on how desert plants gain nutrients...
How can biodiversity be preserved in a world in which traditional ecosystems are increasingly being displaced by “man-made nature”?
Many animals are adapting to human encroachment of their natural habitats. Carnivores in particular require territories of sufficient size and so are often forced to move between numerous small habitat patches.
Climate change affects forests across North America – in some cases permitting insect outbreaks, plant diseases, wildfires and other problems -- but Dartmouth researchers say warmer temperatures are also making many forests grow faster and some less susceptible to pests, which could boost forest health and acreage, timber harvests, carbon storage, water recycling and other forest benefits in some areas.
Over 80% of the world's ice-free land is at risk of profound ecosystem transformation by 2100, a new study reveals.
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, 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 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...
- The deadly nightshade, Atropa Belladonna, which possesses stupefying or poisonous properties.
- A sleeping-potion; a soporific.
- To mutter deliriously.
