The Theory of Island Biogeography

We consider 27 population and community terms used frequently by parasitologists when describing the ecology of parasites. We provide suggestions for various terms in an attempt to foster consistent use and to make terms used in parasite ecology easier to interpret for those who study free-living organisms. We suggest strongly that authors, whether they agree or disagree with us, provide complete and unambiguous definitions for all parameters of their studies.

The Cambridge Structural Database (CSD) contains a complete record of all published organic and metal–organic small-molecule crystal structures. The database has been in operation for over 50 years and continues to be the primary means of sharing structural chemistry data and knowledge across disciplines. As well as structures that are made public to support scientific articles, it includes many structures published directly as CSD Communications. All structures are processed both computationally and by expert structural chemistry editors prior to entering the database. A key component of this processing is the reliable association of the chemical identity of the structure studied with the experimental data. This important step helps ensure that data is widely discoverable and readily reusable. Content is further enriched through selective inclusion of additional experimental data. Entries are available to anyone through free CSD community web services. Linking services developed and maintained by the CCDC, combined with the use of standard identifiers, facilitate discovery from other resources. Data can also be accessed through CCDC and third party software applications and through an application programming interface.

Statistics for Spatial Data.

This book is the second of two volumes in a series on terrestrial and marine comparisons, focusing on the temporal complement of the earlier spatial analysis of patchiness and pattern (Levin et al. 1993). The issue of the relationships among pattern, scale, and patchiness has been framed forcefully in John Steele’s writings of two decades (e.g., Steele 1978). There is no pattern without an observational frame. In the words of Nietzsche, “There are no facts… only interpretations.”

The Problem of Pattern and Scale in Ecology: The Robert H. MacArthur Award Lecture

A series of air and water stable organic cation triiodide salts have been prepared and characterized. Almost all of the salts isolated sustain liquid clathrate phases in the presence of benzene or toluene, the compositions of which were determined via1H NMR spectroscopy. Two of the salts were also characterized via X-ray crystallography in order to determine the nature of any solid state interionic interactions (1-ethylpyridinium triiodide, monoclinic,P21/c,a = 9.6031(7),b = 15.129(3),c = 8.8160(16) A, β = 104.192(11)°,Z = 4,R = 0.041 for 2463 independent observed reflections; 1,2,4-trimethylpyridinium triiodide, orthorhombic,Pbcm,a = 9.434(4), 20.176(4), 7.411(4) A,Z = 4,R = 0.045 for 966 observed reflections).

Se6I2(AsF6)2· 2SO2 has been prepared and its structure determined by single crystal X-ray diffraction; the cation contains a hexaselenium ring of chair conformation with iodine substituents in the axial 1,4 positions.

Oxidation of (η-C5H5)2V with C5H5NO in toluene gives (η-C5H5)4V4(µ3-O)4 and (η-C5H5)5(O)V6(µ3-O)8(1) whereas oxidation with Me3NO gives {(η-C5H5)5V6(µ3-O)8}2{(µ-O)2V(η-C5H5)(NMe3)2} and {(η-C5H5)5V6(µ3-O)8}2(µ-O)(2); the structures of (1) and (2) have been established by X-ray crystallography.

A partially-unlinked cavitand, derived from the condensation of acetaldehyde and resorcinol and having three ethylene bridges, functions as a monodentate ligand toward transition metal ions. Treatment of the cavitand with MCl 2 and a bidendate ligand (L) in the presence of NaOH led to isolation of metal complexes with the formula (cavitand) 2 ML (M=Co, Cu, Zn) or (cavitand) 2 ML 2 (M=Ni). The square-planar complexes of Cu(II) and Co(II), the tetrahedral complex of Zn(II), and the octahedral complex of Ni(II) were characterized spectroscopically and in one case by X-ray crystallography

The reaction of N2O with (η5-C5H5)2V gives (η5-C5H5)5 V5O6, whose structure, determined by X-ray crystallography, shows a trigonal bipyramid of five V atoms, each capped by a (η5-C5H5) ring, with oxygen atoms bridging each of the six faces of the trigonal bipyramid.
