Second-order Nonlinear Optical Microscopy of Spider Silk [PDF]

open access: yes, 2017
Asymmetric $\rm \beta$-sheet protein structures in spider silk should induce nonlinear optical interaction such as second harmonic generation (SHG) which is experimentally observed for a radial line and dragline spider silk by using an imaging ...

Ground spider communities in experimentally disturbed Mediterranean woodland habitats [PDF]

open access: yes, 2011
The protected Mediterranean woodland habitats in Israel are undergoing tree encroachment, resulting in loss of open patches with herbaceous vegetation. We suggested that this process results in a ground spider community dominated by shade-loving species.
