Conservation planning loopholes threaten imperiled species, researchers say

04.07.2006
Multispecies habitat conservation plans may place some species at increased risk

Widely used multispecies habitat conservation plans that permit the incidental "take" of threatened or endangered species often include species that are not confirmed to be present in the planning area, according to a Forum article in the July 2006 issue of BioScience. The plans frequently fail to provide adequate conservation measures for such species, the article argues, and as a result, species that are present but not confirmed to be are placed in increased danger.

Habitat conservation plans are intended to allow development to occur that is compatible with conservation of species listed as endangered or threatened under the Endangered Species Act. Permit seekers often list multiple species in their plans, because if a species not covered by the plan is subsequently listed under the act, this could hinder the continued activities of the permittee. The BioScience article, by Matthew E. Rahn of San Diego State University and two colleagues, analyzed 22 multispecies plans approved by the US Fish and Wildlife Service before 2005. On average 41 percent of the species covered in the plans had not been confirmed as present in the planning area, a result the authors describe as "alarming." Furthermore, most of these unconfirmed species lacked any species-specific conservation measures.

The authors point out that if a species is in fact present but not confirmed as such and therefore not studied, a multispecies habitat conservation plan could actually represent a threat. Most multispecies conservation plans call for nonuniform land use, and such use represents a danger if it is not tailored to the species being protected. Rahn and colleagues argue that "assumptions of occurrence should be justified" in multispecies conservation plans. They suggest that the US Fish and Wildlife Service has been inclined to issue permits for multispecies conservation plans in the absence of data, relying instead on professional judgment. Rahn and colleagues term that a "dangerous practice" and suggest that it may help explain why species in multi-species habitat conservation plans fare poorly compared to species with dedicated plans.

Im Focus: Can the immune system be boosted against Staphylococcus aureus by delivery of messenger RNA?

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.

Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

Im Focus: A quantum walk of photons

Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
