| We review characteristics of birds in boreal forests in the context of their ecological sustainability under both natural and anthropogenic disturbances. We identify the underlying ecological factors associated with boreal bird populations and their variability, review the interactions between boreal bird populations and disturbance, and describe some tools on how boreal bird populations may be conserved in the future. The boreal system has historically been an area with extensive disturbance such as fire, insect outbreaks, and wind. In addition, the boreal system is vulnerable to global climate change as well as increasing pressure on forest and water resources. Current knowledge indicates that birds play an important role in boreal forests, and... |

| Trifurcula (Glaucolepis) lituanica Ivinskis & van Nieukerken, sp. nov., is described from adults reared from stemmining larvae on Salvia pratensis (Lamiaceae) from Lithuania and some specimens taken as adults in Austria, Slovenia and Greece. In addition the new species is recorded from Bulgaria, the Czech Republic and Romania. Superficially, it resembles Trifurcula (Glaucolepis) headleyella (Stainton, 1854), especially the male, but it differs by male genitalia with additional cornuti, a unique character for the subgenus, and the female genitalia differ by the larger number of convolutions in the ductus spermathecae. It is the only known Trifurcula to make its cocoon partially inside a stemmine. The synonymy of Nepticula dubiella Hauder, 1912 with... |

| In the study of diversity patterns, the Mid-domain effect (MDE), which explains gradients in diversity solely on the basis of geometric constraints, has emerged as a null-model against which other hypotheses can be tested. The effectiveness, measured by its predictive power, of these MDE models appears to depend on the size of the study area and the range-sizes of the taxa considered. Here we test the predictive power of MDE on the species richness patterns of birds and assess its effectiveness for a variety of species range sizes. We digitised distribution maps of 889 species of songbird endemic to the Palearctic, and analysed the emergent biogeographic patterns with WORLDMAP software. MDE had a predictive power of 20% when all songbirds were included.... |

| We sequenced 665bp of the Cytochrome C Oxidase I (COI) barcoding marker for 257 specimens and 482bp of Elongation Factor 1-α (EF1-α) for 237 specimens belonging to the leafmining subgenus Ectoedemia (Ectoedemia) in the basal Lepidopteran family Nepticulidae. The dataset includes 45 out of 48 West Palearctic Ectoedemia s. str. species and several species from Africa, North America and Asia. Both COI and EF1-α proved reliable as an alternative to conventional species identification for the majority of species and the combination of both markers can aid in species validation. A clear barcode gap is not present, and in some species large K2P intraspecific pairwise differences are found, up to 6.85% in COI and 2.9% in EF1-α. In the Ectoedemia rubivora species... |

| ABSTRACT A new species, Spilomena capatrata Bashir & Ma, sp. nov. is described from Palearctic and Oriental China. Additionally, eleven species are reported, of which five are new records from China: S. beata Blüthgen, S. hainesi N. Smith, S. menkei R. Bohart, S. punctatissima Blüthgen, and S. valkeilai Vikberg. A key to Chinese species of Spilomena Shuckard is also provided. |
