Conflict or Cooperation? The Social and Political Impacts of Resource Scarcity on Small Island States

This paper examines the social and political consequences of natural resource scarcity on three Pacific island territories: Easter Island, Nauru and Solomon Islands. In contrast to prominent theories in the environmental security literature, the case studies in this paper indicate that resource scarcity does not perforce lead to violent conflict. The authors explain differential outcomes on the basis of four variables: extent of scarcity; level of democracy; degree of economic openness; and involvement in regional regimes.

Taxonomy and ancestral genomic features in <i>S. parasitica</i>.

<p><i>(A)</i> Animal pathogenic and plant pathogenic oomycetes reside in different taxonomic units. <i>(B)</i> Comparison of intron number in phytopathogenic oomycetes (the average count from the total genes of <i>P. infestans</i>, <i>P. ramorum</i>, <i>P. sojae</i>, <i>Py. ultimum</i> and <i>H. arabidopsidis</i>) and <i>S. parasitica</i> among all genes. <i>(C)</i> Significant difference in intron number in 4008 orthologous genes shared by <i>S. parasitica</i> and <i>Phytophthora</i> species (average intron count of <i>P. infestans</i>, <i>P. sojae</i> and <i>P. ramorum</i>). (Wilcoxon test, p<0.001). <i>(D)</i> Large number of chitinase genes belonging to CAZy family GH-18 in <i>S. parasitica</i> (red) compared to other oomycetes (black; Ps = <i>P. sojae</i>, Pr = <i>P. ramorum</i>, PITG = <i>P. infestans</i>, Hp = <i>H. arabidopsidis</i>, Pyu = <i>Py. ultimum</i>, ALNC = <i>A. laibachii</i>). The phylogenetic tree was constructed with chitinase genes from oomycetes using Maximum likelihood method.</p

Molecular genetic events associated with the evolution of animal and plant pathogenesis in oomycetes.

<p>The lineages of animal pathogens are colored red and the lineages of plant pathogens are colored green. The basal lineage is colored brown. S and N pathways refer to sulfite and nitrite assimilation, respectively.</p

Rainbow trout IgM proteolysis by <i>S. parasitica</i> secreted proteases.

<p>(<b>A</b>) 7-day old culture filtrates were capable of degrading rainbow trout IgM after an overnight incubation at 10°C. (<b>B</b>) Schematic drawing of the domains present in the protease SPRG_14567 (<b>C</b>) Expression pattern of SPRG_14567 in different life stages. The RKPM of RNA-seq data is plotted, and the previously identified effector SpHTP-1 is plotted to show contrasting expression patterns. (<b>D</b>) The recombinant subtilisin-like protease SPRG_14567 was partially purified through tandem ion exchange (SO₃⁻) and nickel affinity columns (Fractions 1 to 4) following detection in a Western blot using anti-(His)₅ HRP antibody. (<b>E</b>) Fractions 2, 3 and soluble proteins from untransformed <i>E. coli</i> were tested for IgM-degrading activity with only the fraction containing the recombinant SPRG_14567 exhibiting proteolysis.</p

Predicted horizontally transferred genes that may be associated with pathogenesis in <i>Saprolegnia parasitica</i>.

a<p>Subcellular localization is predicted by the N-terminal signal peptide, mitochondrial targeting motif and transmembrane domains.</p>b<p>The time of horizontal gene transfer is estimated by the presence in other oomycetes and coding potential of a given gene. ‘a recently acquired gene’ refers to a gene occurring only in <i>Saprolegnia</i> and having an uncharacteristic coding potential.</p
