LIMENITIS ARTHEMIS, ETC

Hybrid zone origins, species boundaries, and the evolution of wing-pattern diversity in a polytypic species complex of North American admiral butterflies (Nymphalidae: Limenitis).

Hybrid zones present opportunities to study the effects of gene flow, selection, and recombination in natural populations and, thus, provide insights into the genetic and phenotypic changes that occur early in speciation. Here we investigate a hybrid zone between mimetic (Limenitis arthemis astyanax) and nonmimetic (Limenitis arthemis arthemis) populations of admiral butterflies using DNA seque...

A single origin of Batesian mimicry among hybridizing populations of admiral butterflies (Limenitis arthemis) rejects an evolutionary reversion to the ancestral phenotype.

Batesian mimicry is a fundamental example of adaptive phenotypic evolution driven by strong natural selection. Given the potentially dramatic impacts of selection on individual fitness, it is important to understand the conditions under which mimicry is maintained versus lost. Although much empirical and theoretical work has been devoted to the maintenance of Batesian mimicry, there are no conc...

Introduction etc

Bilateral and multilateral development cooperation agencies are to an increasing extent promoting and adopting a sector-wide approach (SWAp) in their development cooperation. The Swedish International Development Cooperation Agency (Sida), for example, joined their first sector-wide approach cooperation in the late 90s, and today they are involved in SWAps in countries in Africa, Asia and Latin...

MSJ–ETC Editorial

The demand and growth for published research in the field of multiple sclerosis (MS) has increased exponentially over the last few years. The primary aim of the Multiple Sclerosis Journal (MSJ) has always been to reflect the excellent work of the ever-expanding and diverse clinical and research field of MS, and this role will now be shared by MSJ’s companion journal MSJ Experimental, Translatio...
