Many of Florida’s springs and spring runs are enriched in nitrate due to broad-scale contamination of groundwater supplies. This observation fosters two primary and interrelated concerns regarding the effects of nutrients on flora and fauna in spring systems. High nitrate concentrations can affect fauna directly through toxicity. In addition, high nitrate concentrations can promote eutrophicati...

Based on extensive field collections (2000-2014) in Kazakhstan and a review of the material in the National Institute of Zoology of Kazakhstan, we identified 68 species of aquatic Hemiptera from 11 families. Most species have broad zoogeographic distribution, dominated by West Eurasian fauna (18 species) and West Palearctic fauna (10 species). Details of habitats, feeding types, and life histor...

An updated list of Iranian Reduvioidea Latreille (families Pachynomidae, Reduviidae) is presented and discussed in this paper. For Iranian fauna, there are records of one species of Pachynomidae and 109 species and subspecies of assassin bugs (Reduviidae) distributed in 24 genera and subgenera, and seven subfamilies, Emesinae, Harpactorinae, Holoptilinae, Peiratinae, Phymatinae, Reduviinae, and...

With the purpose of determining the principal food resources responsible for maintaining the fishery yield in a section of the São Francisco River, 6 sampling of the fish fauna were made downstream from the Três Marias Dam, from September 1996 to July 1997. A total of 1,127 individuals of 35 species were captured, using gillnets with mesh sizes varying from 3 to 16 cm. The stomach contents of 3...

A review of the ground beetles of the Ukrainian fauna is given. Almost 750 species from 117 genera of Carabidae are known to occur in the Ukraine. Approximately 450 species of ground beetles are registered in the Carpathian region. No less than 300 species of ground beetles are found in the forest zone. Approximately 400 species of Carabidae present in the forest-steppe zone are relatively simi...

The effects of pollution (nutrient enrichment). and the presence of macrovegetation on the species diversity and density of large benthic fauna in the Manukau Harbour, Auckland, were studied by sampling eight soft shore, intertidal habitats. Pollution was found to reduce faunal density but to have only a slight effect on species diversity. The presence of dense meadows of the intertidal seaweed...

The horse fly (Diptera: Tabanidae) fauna of Bosnia and Herzegovina consists of 62 species belonging to ten genera. The present study adds eight new records for the fauna of Bosnia and Herzegovina. These new records are Chrysops flavipes Meigen, Hybomitra tropica (Linnaeus), Tabanus darimonti Leclercq, Tabanus eggeri Schiner, Tabanus miki Brauer in Brauer and Bergenstamm, Tabanus shannonellus Kr...

The first overview on the Auchenorrhyncha fauna of peat bogs of the Austrian Bohemian Forest is presented. Seven oligotrophic peat bog sites were studied in 2011 by suction sampler ("G-Vac") and 93 Auchenorrhyncha species (with 7465 adult specimens) were recorded. Eleven species (about 18 % of the individuals) are tyrphobiontic or tyrphophilous. The relative species abundance plot is not very s...

The eel fauna (orders Anguilliformes and Saccopharyngiformes) of Taiwan is one of the richest in the world. Recent genetic and morphological studies have improved the taxonomic resolution and increased the known diversity of the eels of Taiwan, and the overall diversity is comparable to that of adjacent marine zoogeographic regions with rich biodiversity, such as Australia and the Philippines. ...

Long term studies of Vietnamese Rhopalocera suggest that by using a taxonomic composition analysis of the modern fauna, with ecological and biogeographical characteristics and comparative data with butterfly faunas of adjacent regions, it is possible to offer a plausible account of the history and derivation of the Vietnamese fauna. In former works on the butterfly fauna of Vietnam and of the O...
