Ecosystems are not static things.
Ecosystems with higher biodiversity are more stable as they can easily adjust to changes.
Around the world it is altering ecosystems, changing mating seasons and affecting food supplies.
It has long been known that ecologists need to understand the dynamics of keystone species to understand ecosystems.
In ecosystems, energy is cycled through food chains.
In Triassic terrestrial ecosystems, synapsids and therapsids—ancestors of modern mammals and…
This Technology Quarterly will consider its role in monitoring, preserving and restoring ecosystems and species.
Disturbance plays a significant role in shaping the structure of individual populations and the character of whole ecosystems.
Biodiversity loss is typically associated with more permanent ecological changes in ecosystems, landscapes, and the global biosphere.
Ecological restoration is distinguished from the practice of conservation, which is primarily concerned with preventing further losses to ecosystems.
The target on protecting life-sustaining ecosystems while taking into account the needs of women, indigenous communities and poor people were not met.
“It is impractical to try to restore ecosystems to some ‘rightful’ historical state,” a group of American researchers wrote a few years ago, in Nature.
Mesopredator release, in ecology, a phenomenon in which populations of medium-sized predators rapidly increase in ecosystems after the removal of larger, top carnivores.
Although the distribution of species in freshwater ecosystems is not as well known as for marine and terrestrial ecosystems, it is still clear that species are similarly concentrated.
The convention calls for the conservation of genetic resources by preserving sensitive ecosystems, rehabilitating degraded ecosystems, and enacting legislation that protects endangered plant and animal species.
In many instances, trophic cascades have been initiated by human persecution and harvesting of top carnivores, such as wolves and big cats in terrestrial ecosystems and sharks, tunas, and game fish in aquatic ecosystems.
“It also contradicts Ecuador’s constitution, which recognises the rights of nature and seeks to protect sensitive ecosystems from ‘activities that could lead to species extinction, the destruction of ecosystems, or the permanent alteration of natural cycles’.”
“Humanity now needs to prepare for changes in ecosystems that are faster than we previously envisaged through our traditional linear view of the world, including across Earth’s largest and most iconic ecosystems, and the social-ecological systems that they support.”
“We can only speculate about how the ecosystems change, but we can now ascertain that changes in the reproduction of species are an important factor to include when we try to understand how Arctic ecosystems react to the rising temperatures on the planet,” Dr Høye said.
“I think the combination of theory, modelling and observations is especially persuasive in this paper, and should alert us to risks from human activities that perturb the large and apparently stable ecosystems upon which we depend,” said Georgina Mace, professor of biodiversity and ecosystems at University College London, who was not involved in the studies.
