Links between species' ecological traits and environmental requirements guide conservation planners

09.03.2007
Knowledge of the whereabouts of many species is scarce or incomplete. As a consequence, predictive modelling of species’ distributions has become a prominent field in ecology and conservation.

Such modelling exploits relationships between species' occurrences and characteristic environmental conditions. The accuracy of resulting models is crucial if they are to improve our understanding of patterns in biological diversity and inform conservation decisions.

A new study by McPherson and Jetz in the journal Ecography demonstrates how some species’ distributions are better captured by these models than others' due to inherent differences in their ecological traits.

To estimate the level of uncertainty in model predictions, the authors have examined how species’ characteristics such as body size and diet affect model accuracy in 1329 African bird species. Distribution models are least accurate for migratory and wetland species and species with large geographic ranges. These findings illustrate the interaction between species' ecological attributes and their environmental requirements, a long-standing question in ecology.

From a practical standpoint, the study offers scientists, wildlife managers and policy-makers a rule of thumb for gauging the reliability of species distribution models when careful tests of model accuracy are hampered by lacking data. Moreover the study indicates that reasonable models of current distributions can be achieved for most species, which is excellent news for anyone using distribution models in conservation planning.

Im Focus: Interfacial Superconductivity: Magnetic and superconducting order revealed simultaneously

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

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...
