The type material of the Oriental Carpelimus species from five museums have been investigated. Thirty four lectotypes are designated for the following species: Trogophloeus bengalensis Cameron, 1930; T. bicolor Cameron, 1940; T. calcuttanus Bemhauer, 1911; T. chatterjeei Cameron, 1930; T. congruus Cameron, 1930;T. coriaceus Cameron, 1930; T. flavipennis Cameron, 1930; T. formosae Cameron, 1940;...

Identifying the processes by which new phenotypes and species emerge has been a long-standing effort in evolutionary biology. Young adaptive radiations provide a model to study patterns of morphological and ecological diversification in environmental context. Here, we use the recent radiation (ca. 12k years old) of the freshwater fish Arctic charr (Salvelinus alpinus) to identify abiotic and bi...

plant-based remediation (i.e. phytoremediation) is one of the most significant eco-sustainable techniques to cope with devastating consequences of pollutants. in the present study, the potential of a wetland macrophyt (i.e. potamogeton crispus ) for the phytoremediation of heavy metals (i.e. cu, cr, pb, as and cd) in the anzali wetland was evaluated. the results showed that p. crispus tends to ...

Corn (Zea mays, L.), bean (Phaseolus vulgaris L.), barley (Hordeum vulgare L.), spinach (Spinacia oleracea L.), and sugarbeet (Beta vulgaris L.) grown under iron deficiency, and Potamogeton pectinatus L, and Potamogeton nodosus Poir. grown under oxygen deficiency, contained less chlorophyll than the controls, but accumulated Mg-protoporphyrin IX and/or Mg-protoporphyrin IX monomethyl ester. No ...

The type specimens of Colletes Latreille 1802 deposited in the Zoological Institute, Russian Academy of Sciences (St. Petersburg) are reviewed. Precise information about types of 30 taxa are provided (12 described by J. Noskiewicz; 9 by F. Morawitz; 8 by M. Kuhlmann and M. Proshchalykin; 1 by H. Friese). Lectotypes are designated here and illustrated for the following six nominal taxa: Colletes...
