Forecasts predicting where plants and animals will inhabit over time rely primarily on information about their current climate associations, but that only plays a partial role.
Under climate change, there s a growing interest in assessing whether trees and other species can keep pace with changing temperatures and rainfall, shifting where they are found, also known as their ranges, to track their suitable climates. To test this, a University of Maine-led research team studied the current ranges of hundreds of North American trees and shrubs, assessing the degree to which species are growing in all of the places that are climatically suitable. Researchers found evidence of widespread underfilling of these potential climatic habitats only 50% on average which could mean that trees already have disadvantage as the world continues to warm.
UMaine scientists find that trees are out of equilibrium with climate, posing new challenges in a warming world - UMaine News umaine.edu - get the latest breaking news, showbiz & celebrity photos, sport news & rumours, viral videos and top stories from umaine.edu Daily Mail and Mail on Sunday newspapers.

Abundant and healthy animal carcasses and a suitable habitat with an undisturbed area to lay eggs is all that the vultures in South Asia ask for to thrive.
Of the nine South Asian species of this large ungainly bird, eight are found in Pakistan. These include the Oriental White-backed vulture, the Long-billed vulture, the Red-headed vulture, the Egyptian vulture, the Cinereous vulture, the Lammergeier, the Himalayan Griffon vulture and the Eurasian griffon vulture.
However, the International Union for the Conservation of Nature (IUCN) has placed three of these species on the ‘critically endangered’ list of threatened species. Of these three, the White-backed and the Long-billed vultures are both found in Tharparkar, Sindh.
