Let l=3 or 5. For any integer n>1, we produce an infinite set of triples (L, E1 , E2), where L is a number field with degree l 3(n&1) over Q and E1 and E2 are elliptic curves over L with distinct j-invariants lying in Q, such that the following conditions hold: (1) the pairs of j-invariants [ j(E1), j(E2)] are mutually disjoint, (2) the associated mod-l representations GL=Gal(L L) GL2(Z l) are ...

Effects of invasive plants on arthropods.

Non-native plants have invaded nearly all ecosystems and represent a major component of global ecological change. Plant invasions frequently change the composition and structure of vegetation communities, which can alter animal communities and ecosystem processes. We reviewed 87 articles published in the peer-reviewed literature to evaluate responses of arthropod communities and functional grou...
