Just as in humans the plant microbiome is shaped by the types of bacteria that successfully colonize the plant's ecosystem.
While the findings may exonerate the insect scapegoats they should also help ecosystem managers better respond to changes in the face of climate-driven disturbances like drought and warmer temperatures.
The study team examined ecosystem indicators of fire severity such as how many trees were killed by fire
It's not surprising the ecosystem has these mechanisms to be resilient. What we as people see as catastrophes are not always catastrophes to the ecosystem.

A new paper in the journal Nature Climate Change concludes that climate warming does not accelerate soil organic carbon decomposition or affect soil carbon storage despite increases in ecosystem productivity.
However the temperature gradient used in this study provides an ideal study system for measuring ecosystem responses to warming over long periods of time.
This allowed them to isolate the effects of changing temperature on ecosystem carbon storage and flux.
The scientists propose that where ecosystem carbon is unprotected such as at the surface in plant debris its decomposition
which means that the capacity of tropical ecosystems to retain carbon will depend on the balance of changes within each ecosystem.

which would partially combat the climate change that caused the delay in the first place he said. When plants have green leaves they're doing photosynthesis
Increased feeding by plant-eating tropical fish in temperate waters as a result of ocean warming is an issue of global importance that has the potential to transform marine ecosystems as has also been seen in Japan.
but the ecosystem function hasn't come back said ecologist Mark Bertness professor of biology at Brown and senior author of the study in the journal Biological Conservation.
'but'Does it restore the ecosystem services?''which is really what should be important to us.
The answer is that the recovering ecosystems were not back to performing like healthy ones.
and expensive endeavor that sometimes fails because of the subtle and intricate nature of ecosystems Bertness noted.
therefore that ecosystem management cannot be judged as successful based merely on how the marshes look.
Three decades ago forest dieback was a hot topic with the very survival of large forest ecosystems seemingly in doubt.
Meanwhile the accelerated growth and aging of trees is also significant for the forest ecosystem as a whole as Pretzsch explains:

Despite the fact that tropical forests are the most biodiverse terrestrial ecosystems on the planet more is known about bellybutton bacteria than bacteria on trees in the tropics.
Later the culture regressed as the ecosystem in the area shifted towards old-growth spruce-dominated forests
and regressed as the ecosystem became dominated by old-growth spruce forests which provided a less ideal elk habitat than the recently-emerged land.
Preserving biodiversity and phylogenetic history is critical for both healthy ecosystems and prosperous farms Frishkoff and Karp said.
Having just sparrows in an ecosystem is like investing only in technology stocks: If the bubble bursts you lose Frishkoff said.
You want to have diversified a truly ecosystem with an array of species each contributing different benefits.
from now on we will have a much more detailed view of the dynamics of this ecosystem says Dusko Ehrlich.
It looks to birds as indicators of ecosystem health by examining population trends of species dependent on one of seven habitats:
Andreas Huth have spent the last five years using computer models to analyse ecosystems to explore the composition and dynamics of species-rich communities in tropical rainforests.
Called the Global Ecosystem Dynamics Investigation (GEDI) lidar the instrument will be the first to systematically probe the depths of the forests from space.
This study shows that it can be a promising option to protect European forests from the impacts of climate change says IIASA Ecosystems Services

Areas with carbon-rich ecosystems with key wilderness habitats such as tropical forests were identified as those where new roads would cause the most environmental damage with the lease human benefit particularly areas where few roads currently exist.
and in forests it can survive in widely diverse ecosystems and has been found to impact native plant species invertebrate populations and soil nutrients.
Ecosystems are so incredibly complex that it can be surprisingly difficult to foresee just how environmental changes such as an invasion will affect organisms living in affected areas said Devore who is now a postdoctoral fellow with the University of Sydney in Australia.
Maerz has been interested in the effects of Japanese stiltgrass on forest ecosystems for years When Devore and Maerz originally found lower survival of American toads at eight locations in Georgia where stiltgrass is actively invading they initially speculated that the grass was reducing the toads'food supply by reducing insect populations--few native insects eat the Asian

which could fundamentally transform current ecosystems. A symposium focusing on climate's effects on predators--causing cascading effects on whole ecosystems--will take place on Tuesday August 12th during the Ecological Society of America's 99th Annual Meeting held this year in Sacramento California.
There will be winners and losers as species adapt to a changing climate. Ecologists are just beginning to understand why different competitors may be favored by climate change
Impacts on one species can affect many organisms in an ecosystem. Because predator species are animals that survive by preying on other organisms they send ripples throughout the food web regulating the effects other animals have on that ecosystem.
This cause and effect process is called a trophic cascade or the progression of direct and indirect effects predators have across lower levels in a food chain.
and functioning of temperate nearshore marine ecosystems said Rebecca G. Martone of the Center for Ocean Solutions at Stanford university.
Dr. Martone's analyses of the effects of sea otters on kelp forest ecosystems can help shape predictions of how climate change
and trophic cascades in concert with other drivers affect coastal ecosystems. The ecological impacts of a changing climate are evident from terrestrial polar regions to tropical marine environments.
and three raptor species commonly found in sagebrush ecosystems: Red-tailed hawks Swainson's Hawks and Ferruginous Hawks.
Raven populations have increased precipitously in the past four decades in sagebrush ecosystems largely as a result of fragmentation and development of anthropogenic structures.

when we talk about wildfire in California we are talking about two very different fire regimes in two different ecosystems:
The chaparral shrublands of southern California and similar sagebrush ecosystems in the Great Basin are adapted not to the kind of frequent fire typical of the mountain conifer forests in California.
Fires in the lower elevation ecosystems are always crown fires which kill most of the vegetation.
In the millennia before humans arrived these ecosystems burned at intervals of 100 to 130 years.
These lower elevation ecosystems experienced unprecedented fire frequency in the last century with fire returning to the same area every 10 to 20 years altering the ecology of the landscape.
In Southern California lower elevation ecosystems have burned more frequently than ever before. I think it's partly climate
To Keeley this means that prescribed fires in lower elevation ecosystems now have entirely different consequences for the regional ecology than they did
and a synthesis of what is known about the effects of fire on forest ecosystem services such as water quantity and quality air quality and biodiversity.
Long-lived ecosystems such as forests are particularly vulnerable to the comparatively rapid changes in the climate system.
Disturbances like windthrow and forest fires are part of the natural dynamics of forest ecosystems and are not therefore a catastrophe for the ecosystem as such.
However these disturbances have intensified considerably in recent decades which increasingly challenges the sustainable management of forest ecosystems says Rupert Seidl BOKU Vienna the principal researcher involved in the study.
The authors show that damage caused by forest disturbance has increased continuously over the last 40 years in Europe reaching 56 million cubic meters of timber per year in the period 2002--2010.
in order to keep sustaining the diverse set of ecosystem services provided to society in the future the study concludes.
When subsistence practices have long histories they are more likely to sustain ecosystem stability he says.
In fact they see humans as part of a larger ecosystem that has spiritual components--the dreamtime place of creation where ancestors roamed.
So perhaps it's not surprising to them it has positive results for the ecosystem.

and dangers of the introduction of the yellow crazy ant to the uniqueendemic ecosystem of the mature palm forest of the Vallã e de Mai a UNESCO World Heritage Site on the Seychelles.
The palm forest of Vallã e de Mai is a unique ecosystem containing many endemic species including the iconic coco de mer palm Lodoicea maldivica.
Although the impacts and ecology of A. gracilipes have been documented well in degraded habitats in the Seychelles little is known about this ant's invasion potential in endemic palm forest ecosystems.
This habitat represents one of the last island palm forest ecosystems in the world and hosts many species that are endemic to Praslin
The current restricted distribution of A. gracilipes in this ecosystem combined with lower abundance of endemic fauna in the invaded area highlight the need for further research.

and ecosystems to facilitate the storage of carbon could be dramatic. In their study Tamura and Tharayil examined the impact of encroachment of Japanese knotweed and kudzu two of North america's most widespread invasive plants on the soil carbon storage in native ecosystems.
They found that kudzu invasion released carbon that was stored in native soils while the carbon amassed in soils invaded by knotweed is more prone to oxidation
Climate change is causing massive range expansion of many exotic and invasive plant species. As the climate warms kudzu will continue to invade northern ecosystems
Converting diverse forest ecosystems to these single-crop monocultures degrades or destroys wildlife habitat. Oil palm plantations also have been associated with dangerous and abusive conditions for laborers.
Although we previously documented carbon emissions from land use conversion to oil palm we were stunned by how these oil palm plantations profoundly alter freshwater ecosystems for decades said study co-author
because this study is one of the first to examine the oil palm's effects on freshwater ecosystems.
and diverse smallholder agricultural lands to oil palm plantations may be almost as harmful to stream ecosystems as clearing intact forests.
Very few protections for such non-intact forest ecosystems exist. According to Curran extensive land conversion to oil palm plantations could lead to a perfect storm combining the crop's environmental effects with those from a massive El Niã o-associated drought.
This could cause collapse of freshwater ecosystems and significant social and economic hardships in a region Curran said.
