Across taxa, reductions in insulin signaling and/or responsiveness are used as organismal signals for various types of stress – for example, IIS is involved in the entry into dauer in C. elegans.
The PhyloChip data also demonstrated taxa diversity reduction for nitrifying bacteria in R1 (50 µg/L of ERY-H2O) and R2 (100 µg/L of ERY) comparing with R3 (control; Table 1).
Assemblage expansion means upward increase in diversity and frequency of normal marine taxa, while assemblage reduction means upward decrease of the same proxies.
Community composition of understory riparian vegetation changed post-fire, most likely as a result of the reduction in taxa richness and cover.
The primary change between the shallower areas and the deeper areas is the reduction of taxa within the Chondrichthyes in the zones deeper than 600 m.
In all cases, Devonian taxa exhibited a congruent reduction in speciation rate between the Middle Devonian pre-crisis interval and the Late Devonian crisis interval.
Using genome size as an indicator of proteome diversity, orthologous protein sets were identified in two distinct bacterial lineages that included taxa exhibiting extreme genome reduction.
CI affects a broad range of insect taxa and causes a reduction in egg hatch when Wolbachia-uninfected females and Wolbachia-infected males mate.
As continental ice sheets advanced into temperate areas, rendering once suitable areas uninhabitable, many northern taxa experienced extreme range reduction and fragmentation into refugia, while other populations and taxa were decimated entirely.
This idea is completely corroborated with numerous data that the last common ancestor of Deuterostomia, Ecdysozoa and Spiralia had a segmented and coelomate body organization and that morphologically more simply organized taxa evolved by secondary reductions [ 74– 74].
