Host preferences of aphidophagous hoverflies from field distribution of their larvae
The patterns of occurrences among aphid colonies of the larvae of two species of highly polyphagous predatory hoverflies, Episyrphus balteatus (de Geer) and Syrphus ribesii (L.) (Diptera: Syrphidae), were assessed in three areas (Nottingham, Cardiff (UK) and the Czech Republic); in the last two sites, larvae of other syrphid species...Sadeghi, Hussein ; Rotheray, Graham E ; Laska, Pavel ; Gilbert, Francis

Further records of biting midges (Diptera: Ceratopogonidae) from Upper Cretaceous Burmese amber (Myanmar)
A new biting midge Archiculicoides andersoni sp. nov. from Upper Cretaceous Burmese amber is described and illustrated. An unknown male of Leptoconops myanmaricus Szadziewski, 2004 is described and an undetermined female of the genus Archiaustroconops and Austroconops in the collection of National Museums Scotland is reported. A key for the...Szadziewski, Ryszard ; Ross, Andrew ; Wojciech, Giłka

Splitting or lumping? A conservation dilemma exemplified by the critically endangered Dama Gazelle (Nanger dama)
Managers of threatened species often face the dilemma of whether to keep populations separate to conserve local adaptations and minimize the risk of outbreeding, or whether to manage populations jointly to reduce loss of genetic diversity and minimise inbreeding. In this study we examine genetic relatedness and diversity in three...Senn, Helen ; Banfield, Lisa ; Wacher, Tim ; Newby, John ; Rabeil, Thomas …

Palaeontology: Chinese amber insects bridge the gap
In the study of fossil insects, Chinese amber from Fushun has been largely overlooked. A new study now reveals a highly diverse biota and provides a wealth of new information on the past Asian insect fauna.Ross, Andrew

Land-bridge calibration of molecular clocks and the post-glacial colonization of Scandinavia by the Eurasian field vole Microtus agrestis
Phylogeography interprets molecular genetic variation in a spatial and temporal context. Molecular clocks are frequently used to calibrate phylogeographic analyses, however there is mounting evidence that molecular rates decay over the relevant timescales. It is therefore essential that an appropriate rate is determined, consistent with the temporal scale of the...Herman, Jeremy S ; McDevitt, Allan D ; Kawalko, Agato ; Jaarolo, Maarit ; Wójcik, J M …

Detecting the elusive Scottish wildcat Felis silvestris silvestris using camera trapping
Population monitoring is important for conservation management but difficult to achieve for rare, cryptic species. Reliable information about the Critically Endangered Scottish wildcat Felis silvestris silvestris is lacking because of difficulties in morphological and genetic identification, resulting from extensive hybridization with feral domestic cats Felis catus. We carried out camera-trap...
