Nature is on the move. As the impacts of climate change reveal themselves, species and ecosystems are moving in response. This poses a fundamental challenge to conservation organizations—how do you conserve something that won't stay still?
A new paper authored by a University of Tennessee, Knoxville, professor suggests that in order to cope, conservation organizations need to adapt like the organisms they seek to protect.
The paper, published in Frontiers in Ecology and the Environment, argues that conservation organizations need to be bolder in their adaptation efforts given the rate and extent of the ecological changes that are coming. The article can be found at http://bit.ly/1B7rclb
As the climate warms and other global changes progress, species move outside their historical ranges, new ecological communities form and ecosystems transition to new states. Moreover, scientists are predicting that these changes will accelerate in the future.
"If you are an organization that has focused on conserving particular species in a particular place, as many of today's conservation organizations are, then something has to give—either you need to change your business model or revisit your conservation priorities. And neither is going to be easy for some of these groups," said Paul Armsworth, lead author and associate professor of ecology and evolutionary biology.
The paper puts forward a number of new ideas for how conservation organizations might address the challenges they are facing. It also highlights stories of success.
For example, Scenic Hudson, an environmental and land conservation group in New York State, has updated the way it prioritizes parts of the landscape for protection to better incorporate a changing climate, especially the impacts of sea-level rise. To get out ahead of the issue, in 2008 the group hired an experienced conservation biologist, created a detailed plan for shifting its land conservation along the Hudson River and developed resources to help local communities along the waterway adapt to rising sea levels.
"Previously, we focused on conserving places that harbor the most important habitats and species today," said Sacha Spector, Scenic Hudson's director of conservation science.
"But then we looked at the projections for sea-level rise in our region. Continuing with business as usual would have left us quite literally under water. Now when prioritizing sites for protection, we also look to acquire areas upslope to open up the possibility for the habitats we are targeting to migrate as the climate changes."
Spector said the paper's suggestions were right on target.
"What the authors are saying certainly resonates with our experiences here in the Hudson Valley," he said. "For example, the authors appeal for conservation organizations to start evaluating over what time period their investments in habitat protection are likely to provide conservation benefits.
We must recognize that if you are in for the long term—as most conservation organizations expect to be—you are going to have to ensure that the investments you make today align with the conditions you expect for the future. This matches very closely with our new approach to protecting the Hudson's tidal habitats."
The paper was produced by a team of authors from universities, conservation nonprofits and relevant federal agencies.

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
