Effects of pollution-induced changes in oxygen conditions scaling up from individuals to ecosystems in a tropical river network.

Anthropogenic inputs of nutrients and organic matter are common in tropical lowland rivers while little is known about the pollution-induced changes in oxygen availability and respiratory performance of ectotherms in these high temperature systems. We investigated the effects of agriculture and urban land-use on river water oxygen levels (diel measurements), decomposition rates (Wettex) and macroinvertebrate assemblages (field studies), as well as the oxy-regulatory capacity of eight riverine macroinvertebrate taxa (laboratory study) from a tropical lowland river network in Myanmar. The highest decomposition rates (0.

Revision of the group (Diptera: Mycetophilidae).

Background: is a diverse genus of small fungus gnats, widespread in the Holarctic Region, while the fauna is largely unknown elsewhere, such as in the Afrotropical and Oriental Region. Members of can be arranged into several species groups, based on homologies in the male and female terminalia. The group is delimited, based on male terminalia possessing a pair of gonocoxal lobes on the apicoventral gonocoxal margin.

New data on the genus Manota Williston (Diptera: Mycetophilidae) from Africa, with an updated key to the species.

A total of 346 male specimens of Manota collected from 13 countries in Africa are studied. They belong to 40 different species including 12 new to science. The new species are: M.

Winnertz from the Himalayas, with nine species new to science (Diptera, Mycetophilidae).

An extensive collection of fungus gnats from Nepal and Bhutan, deposited at Kyushu University Museum in Japan, has been examined and revealed nine species of Winnertz, 1864 new to science: Magnussen, , Magnussen, , Magnussen, , Magnussen, , Magnussen, , Magnussen, , Magnussen, , Magnussen, , and Magnussen, All specimens were collected at high altitudes in the central and eastern Himalayas. The species all belong to the subgenusAllodia s. str.

Six new species of Afrotropical Allodia (Diptera: Mycetophilidae): DNA barcodes indicate recent diversification with a single origin.

Only one species of the genus Allodia has been previously recorded from the Afrotropical region, Allodia (Brachycampta) flavorufa Matile, 1978. Six new species are described here, all representing the nominotypical subgenus, Allodia s.s.
