The homeodomain of the Drosophila Ceramide Synthase Schlank confers nuclear import information and DNA binding capabilities
(2014-05-15)
Ceramide Synthases (CerS) are membrane bound enzymes at the center of the sphingolipid synthesis cascade. A sub-class of CerS also codes for a homeodomain of unknown function.

Ecology and Population Status of the Puku Antelope (Kobus vardonii LIVINGSTONE, 1857) in Zambia
(2014-02-18)
Road surveys along line transects were conducted at different times during the dry season. Puku occurred in small to large groups. They preferred grassland where estimated population densities were 36.15 puku/km² in Kasanka ...
A survey of the German mosquito fauna (Diptera: Culicidae) and identification of associated pathogens
(2015-02-13)
As a consequence of fundamental environmental, economic and demographic changes worldwide, vector-borne diseases are becoming of increasing public and animal health significance in Europe, owing to their geographical ...
Virus diversity and cross-species transmission of viruses from the strawcoloured fruit bat Eidolon helvum
(2015-01-06)
Bats are increasingly recognized as hosts of viruses which are significant for human and domestic health. However, the dynamics of these viruses in their natural hosts remain poorly elucidated. In this study, virus diversity ......
Entwicklung eines bionischen Infrarotsensors: Evaluation von Materialparametern und Sensorkonzepten
(2015-07-07)
Der schwarze Kiefernprachtkäfer Melanophila acuminata besitzt zwei paarig angeordnete infrarotsensitive Grubenorgane mit jeweils etwa 70 miniaturisierten IRSensillen.

A new methodology to use color spectral data for taxonomic, phylogenetic, and biogeographic studies: An example with three genera of lowland hummingbirds: Topaza, Anthracothorax, and Eulampis
(2005)
I developed a methodology to obtain and compare integral information on bird plumage coloration, using color spectral data to conduct studies on geographic variation, taxonomy and phylogeny of different bird groups. I used ...
Funktionsmorphologische Untersuchungen abdominaler Infrarot-Rezeptoren von Insekten
(2014-12-12)
Infrarot (IR) -Rezeptoren sind innerhalb der Insekten offensichtlich mehrfach unabhängig voneinander entstanden. Bei den Vertretern der Gattung Melanophila, einigen Rindenwanzen der Gattung Aradus und bei dem australischen ...
Adaptation primärer Afferenzen und Hirnstammneuronen im Seitenliniensystem des Goldfisches, Carassius auratus, auf sequenzielle Reize
(2016-07-29)
Weltweit sind ca. 33.000 Fischarten beschrieben, die sich in ihren Lebensraumansprüchen und in ihrer Lebensweise oft deutlich voneinander unterscheiden. Alle bisher beschriebenen Fische und aquatisch lebende Amphibien ......
In their aquatic environments fishes and aquatic amphibians can detect minute water movements. Both, the incompressible flow in the near field and propagated pressure waves are detected by the lateral line. The sensory ......

Biodiversity of leaf beetles (Coleoptera: Chrysomelidae) in a tropical montane rainforest ecosystem assessed with DNA barcoding
(2016-08-09)
The aim of the present study was the assessment of an unknown tropical insect fauna without traditional taxonomy. For this purpose, the diversity of leaf beetles (Coleoptera: Chrysomelidae) in the montane rainforest of the ...
The oscillatory mechanisms of working memory maintenance
(2016-06-14)
Working memory (WM) is a cognitive process which allows for maintenance of information that is no longer perceived. Although theoretical models have recognized that working memory involves interactions across cell assemblies ...
