The genus Acanthaleyrodes Takahashi is reported for the first time from India. Acanthaleyrodes elevatus sp. n. is described from Bridelia retusa in Kerala, India, with a key to puparia of Acanthaleydes species. The new species differs in its exceptionally elevated eighth abdominal tergite, circular vasiform orifice and eight pairs of subdorsal setae. The generic characteristics of Acanthaleyrod...

Major rivers produce large plumes which subsidize benthic marine food webs. Because most plumes are smaller, we tested whether these also can link marine food webs with riverine discharges. We used stable isotopes to detect assimilation of terrestrial organic matter by fish, crustaceans and cephalopods harvested from plume areas off two small estuaries in eastern Australia, contrasted with valu...

Abstract Brachionus calyciflorus is a species complex consisting of four recently described species. Although several lines evidence support their status, hybridization between two the sibling B. s.s. and elevatus has been inferred from both field laboratory studies. In this study, we tested for existence prezygotic barriers these by performing types cross-fertilization experiments. ‘mate compe...

Thirty-two species of Hybotidae (Diptera: Empidoidea) were collected during the Boyekoli Ebale Congo 2010 Expedition that took place in the Democratic Republic of Congo along the Congo River between Kisangani and Bumba. Only four species were known previously. Here we present new records for Syndyas crisis Garrett Jones, 1940 and Crossopalpus aenescens (Wiedemann, 1830). In addition Syneches el...

this study describes length-weight relationships of five species (platycephalus indicus, pseudorhombus elevates, plicofollis tenuispinis, grammoplites suppositus, pomadays stridens) collected from persian gulf (khuzestan province, iran) during december 2009 to november 2011. a total of 2065 specimen were examined for this study. the relationship between weight and total length were estimated: w...

Background During a field course on spider taxonomy and ecology at the University of Helsinki, the authors had the opportunity to sample four plots with a dual objective of both teaching on field methods, spider identification and behaviour and uncovering the spider diversity patterns found in the southern coastal forests of Hankoniemi, Finland. As an ultimate goal, this field course intended t...
