1. Why are Drosophila larvae more sensitive to avermectin than adults?

The insects have different physiological and morphological characteristics in various developmental stages. The difference in the characteristics may be related to the different sensitivity of insects to insecticides. In avermectin resistant strain screening assay, we found that the Drosophila...

9. Road salt compromises functional morphology of larval gills in populations of an amphibian.

Across the planet, winter de-icing practices have caused secondary salinization of freshwater habitats. Many amphibians are vulnerable because of permeable skin and reliance on small ponds, where salinity can be high. Early developmental stages of amphibians are especially sensitive to salt, and...

10. Introduction.

Given the rich rainforest flora of Papua New Guinea, which includes some 8000 known plant species, it is understandable why this land mass contains such a rich dacine fauna, with the largest number of species of any land mass across the entire Asian/Pacific region. Major collections of Dacini have...

12. Direct and indirect effects of chronic exposure to ammonium on anuran larvae survivorship, morphology, and swimming speed.

Several constituents of the current global change are usually deemed accountable for the worldwide declines of amphibian populations. Among these, water contamination poses a major threat, especially to larval stages, which are unable to escape a polluted water body. This problem is remarkable in...

14. Species and speciation.

This chapter discusses two species models, which are diametrically opposed. The first, often called the 'biological species concept', defines species in terms of 'reproductive isolation', convinced that species arise when subsets of a population are split off and remain geographically isolated over ...

23. Predicting the occurrence of host-associated differentiation in parasitic arthropods: a quantitative literature review.

Parasite populations associated with different host species can encounter a variety of isolating reproductive barriers, leading to each population independently accumulating genome-wide genetic differences due to their host associations. This phenomenon is called host-associated differentiation...
