Tree trunks are important links between the forest floor and canopy, especially for flightless invertebrates that move from the forest floor to feed or breed in the canopy. Traps were used to sample invertebrates moving up and down on mahoe (Melicytus ramiflorus), hinau (Elaeocarpus dentatus), hard beech (Nothofagus truncata), and kamahi (Weinmannia racemosa). In 19 months 22 696 invertebrates ...

Descriptions are presented of new species of water mites from two mountains in the Malaysian part of Borneo. A new subgenus of the genus Javalbia (Hygrobatidae), i.e. Megapes n. subgen., and 34 new species are described: Limnocharidae: Limnochares (Limnochares) spinosa n. sp.; Oxidae: Oxus (Oxus) fuscus n. sp.; Hydryphantidae: Protzia borneoensis n. sp.; Sperchontidae: Sperchon kinabaluensis n....

The physical and chemical properties of poplar clones largely determine their suitability for different applications. The main objective of this study was to investigate clonal variation in four hybrid poplar clones grown at three sites in North China and identify the superior clone. Study materials were collected from four clones of hybrid white poplar: Populus tomentosa “LM50”, used as the co...

Organochlorine contaminants (OCs) and stable isotopes of carbon (δ13C) and nitrogen (δ15N) were determined in 7 benthic and 7 pelagic marine invertebrate species from the North American Arctic to identify factors influencing OC concentrations. Values of δ13C separated benthic (enriched in 13C) from pelagic species and δ15N values gave a logical approximation of trophic level (TL). With few exce...

(1) Background: The Quaternary river bank deposits of the European North Russia contain several mollusk fossils that can give important past-climate information which is relevant to understand evolution climate in Holocene period and predict future scenarios on change. (2) purpose research: reconstruction main physical chemical parameters habitat mollusks based determination species study isoto...

Abstract Earwigs have been observed as an irregular pest of increasing concern to farmers growing canola and other winter grain crops in Australia over the past decade. In this study, we tested how abiotic biotic factors influence feeding behaviour earwigs. Studies were conducted with two Australian native species, Labidura truncata Nala lividipes , introduced European earwig, Forficula auricul...
