Decrease in feeding niche breadth of Melasoma lapponica (Coleoptera: Chrysomelidae) with increase in pollution.

Oecologia

Zyereva EL, Kozlov MV, Neuvonen S.
PMID: 28307589
Oecologia. 1995 Nov;104(3):323-329. doi: 10.1007/BF00328368.

We studied host-plant preference and performance of the leaf beetle, Melasoma lapponica, around Severonikel smelter situated in Monchegorsk, Russia. The breadth of feeding niche (Smith's measure) based on both field counts and preference tests decreased with an increase of...

PMID: 28308059
Oecologia. 1999 Jul;120(1):92-101. doi: 10.1007/s004420050837.

We studied topographical and year-to-year variation in the performance (pupal weights, survival) and larval parasitism of Epirrita autumnata larvae feeding on mountain birch in northernmost Finland in 1993-1996. We found differences in both food plant quality and parasitism between...

[structures: see text] Propagation of inductive and resonance effects of phenyl substituents within 1-(substituted phenyl)-6,7-dimethoxy-3,4-dihydro- and -1,2,3,4-tetrahydroisoquinolines were studied with the aid of 13C and 15N NMR chemical shifts and ab initio calculations. The substituent-induced changes in the chemical...

Simulated acid rain affects birch leaf endophyte populations.

Microbial ecology
