Novel microsatellite loci isolated from the northern krill, Meganyctiphanes norvegica (Crustacea, Euphausiacea)

Abstract

Five loci amplified successfully and were polymorphic (Table 1). Two other loci also amplified products, but persistent stuttering prevented reliable scoring despite optimization and, in one case, primer redesign. Locus Co12E10 showed significant deviation from Hardy-Weinberg equilibrium ( χ 2 -test; P < 0.05). Null allele frequency estimates using cervus (Marshall et al . 1998) indicated possible null alleles at loci Co12E10 (frequency = 0.086) and Co9C11 (frequency = 0.031). At locus Co12E10 a consistently nonamplifying offspring further suggested the presence of a null allele (Pemberton et al . 1995). Caution is therefore required for parentage assignment based on exclusion at this locus.

Systematic sequencing of mRNA from the Antarctic krill (Euphausia superba) and first tissue specific transcriptional signature

“…These markers will increase the currently available Euphausiacea SSR markers. In fact, only five microsatellite loci isolated from the northern krill Meganyctiphanes norvegica have been reported so far [ 37 ]. Since our novel microsatellite markers were developed on the basis of expressed sequences and they are presumably conserved across other Euphausiacea species, they could also be useful for comparative mapping and for a molecular approach to Antarctic krill ecology.…”

Genetics of Northern Krill (Meganyctiphanes norvegica Sars)

“…Two loci were from a previous isolation report (MnC7 and MnO8; Ostellari et al, 2000). It should be noted here that such a limited number of microsatellite markers do not allow any firm conclusion.…”

Echolocation and Stratum Preference: Key Trait Correlates of Vulnerability of Insectivorous Bats to Tropical Forest Fragmentation

“…Primary tropical forests are characterized by marked vertical complexity that creates a pattern of differential use of space by organisms (Bernard, 2001;Marques et al, 2015). Bats move through space three-dimensionally, and as a consequence, forest structure and vegetation clutter may affect not only horizontal patterns of bat activity but also vertical patterns (Hayes and Gruver, 2000;Jung et al, 2012;Mas, 2014). In fact, most of the foraging activity of bats occurs in the canopy, the upper forest layer (Kalko and Handley, 2001;Vetter et al, 2011;Marques et al, 2015;Marques, 2016).…”
