Wildlife Biology, EarlyView.The shift to ‘close to nature forestry' as the dominating forestry regime in western‐European forests has resulted in increasing timber volume and denser forests with negative effects on photophilic species. Hence, there is an increasing focus on active habitat management measures to support these species.

New renormalization group approach and scaling laws for the Lifshitz critical behavior [PDF]
arXiv, 2001 A new renormalization group treatment is proposed for the critical exponents of an m-fold Lifshitz point. The anisotropic cases (m not equal 8) are described by two independent fixed points associated to two independent momentum flow along the quadratic and quartic directions, respectively. The isotropic case is described separately.

Kluwer, 41--48, 2002 We introduce and completely describe the analogues of the Riemann curvature tensor for the curved supergrassmannian of the passing through the origin (0|2)-dimensional subsupermanifolds in the (0|4)-dimensional supermanifold with the preserved volume form.

Adaptabilidade e estabilidade em cultivares de sorgo
Revista Brasileira de Zootecnia, 2002 As informações sobre o comportamento de cultivares obtidas em apenas um local e ano podem não ser suficientes para recomendar uma cultivar, em função da ocorrência de interação genótipo x ambiente.

The Howe duality and Lie superalgebras [PDF]
S. Duplij and J. Wess (eds.) Noncommutative structures in
mathematics and physics. Proc. NATO Advanced Research Workshop, Kiev, 2000.
Kluwer, 93-111, 2002 Howe's duality is considered from a unifying point of view based on Lie superalgebras. New examples are offered. In particular, we construct several simplest spinor-oscillator representations and compute their highest weights for the 'stringy' Lie superalgebras (i.e., Lie superalgebras of complex vector fields (or their nontrivial central extensions ...

Biodiversity–food trade‐offs when agricultural land is spared from production
American Journal of Agricultural Economics, EarlyView.Abstract Biodiversity conservation in agricultural landscapes, the world's predominant land use, could involve sparing, or setting aside, agricultural land from production, implying biodiversity–food trade‐offs. Employing bird species and agricultural data in two panel data sets, we evaluate the extent of set‐aside's trade‐offs in England between 1992 ...
