New study reveals large scale conservation essential

11.06.2008
Surprising findings for amphibians, turtles and marine species

Scientists were surprised with findings of a recent study that reveals many animal species believed to persist in small contained areas actually need broad, landscape level conservation to survive.

With more species at risk of extinction today than any other time in human history, the findings of the study published in the debut issue of Conservation Letters provides new insight into how to improve protection for many species worldwide. Scientists from organizations including Conservation International (CI) and BirdLife International identified appropriate scales of conservation efforts for 4,239 species of mammals, birds, reptiles, and amphibians included on the IUCN Red List of Threatened Species.

"The biggest surprise was the frogs," said Claude Gascon, executive vice president for programs and science at CI, and co-chair of the IUCN Amphibian Specialist Group. "Amphibians are small animals, and many have tiny ranges restricted to a single forest or a mountain stream. But astonishingly many species -- like the Critically Endangered Lake Titicaca Giant Frog (Telmatobius culeus) from Peru -- are greatly impacted by ecological processes at the landscape scale."

Many freshwater species, such as frogs and other amphibians, are threatened by environmental changes to watersheds or river basins impacted by pollution, deforestation or dams. The study found that 20 percent of threatened amphibians, and no less than 40 percent of threatened freshwater turtles, depend on broad-scale conservation action to address changes in freshwater processes.

"It's not that these animals themselves need a huge area per se, but rather that comprehensive and successful strategies must include various scales of action from sites to landscapes" Gascon added. "But we have to think about how we impact the quality and flow of freshwater across entire landscapes. And remember that people need those flows of clean freshwater across landscapes in the same way that frogs do."

The establishment of protected areas to safeguard key biodiversity areas has been long considered the most effective means to protect threatened species. The study reinforces this assumption, showing that the protection of key sites must remain the foundation for all conservation efforts. However, it also showed that considerably more threatened species need urgent conservation action at the landscape or seascape level than previously believed. Fully one in five threatened vertebrates require urgent conservation action at the landscape or seascape scale, including such flagship species as the Tiger (Panthera tigris) and the Philippine Eagle (Pithecophaga jefferyi).

The study also covered marine mammals, seabirds and sea turtles, and showed that 74 percent of these require urgent seascape level action. These include species like the Galápagos Fur Seal (Arctocephalus galapagoensis) and the Waved Albatross (Phoebastria irrorata), from the Eastern Tropical Pacific. "While the need for seascape conservation is overwhelming for these species," cautioned Charlotte Boyd, the study's lead author and now a marine ecologist at the University of Washington, "we urgently need equivalent assessments for fish to obtain a more comprehensive picture of what conservation actions are needed where in marine systems."

Overall, the study provides strong new evidence supporting the integration of multiple scales of conservation, including protected areas as well as landscape and seascape level conservation strategies.

"Our key conclusion is that both site-scale and broad-scale conservation are essential to prevent mass extinction," said Thomas Brooks, from the CI Center for Applied Biodiversity Science. "We recognize that site protection is the cornerstone for almost all threatened species. We are now also certain that a substantial proportion and unexpected diversity of threatened species will be lost without urgent conservation intervention at the sea or landscape level."

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...

Im Focus: How to inflate a hardened concrete shell with a weight of 80 t

At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).

Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...

Im Focus: Bacterial Pac Man molecule snaps at sugar

Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.

The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...

Im Focus: Repairing defects in fiber-reinforced plastics more efficiently

Fiber-reinforced plastics (FRP) are frequently used in the aeronautic and automobile industry. However, the repair of workpieces made of these composite materials is often less profitable than exchanging the part. In order to increase the lifetime of FRP parts and to make them more eco-efficient, the Laser Zentrum Hannover e.V. (LZH) and the Apodius GmbH want to combine a new measuring device for fiber layer orientation with an innovative laser-based repair process.

Defects in FRP pieces may be production or operation-related. Whether or not repair is cost-effective depends on the geometry of the defective area, the tools...
