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 ...
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.
Jede dieser Sensillen bestehen aus einer ...

MicroRNAs in the bovine ovary and placentas derived from in vivo, in vitro and nuclear transfer pregnancies
(2010-12-15)
MicroRNAs are the major class of gene regulating molecules playing pivotal roles at post-transcriptional level. Identification and expression profiling are the initial steps to understand their regulation of biological ...
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 ...
Oxytocin – the prosocial molecule?: Intranasal oxytocin effects on social approach behavior, social cognition, volitional and emotional ambivalence in healthy human beings
(2015-10-30)
Oxytocin (OXT) is a highly conserved neuropeptide, regarding both its chemical structure and its functionality. It has been traced back at least 700 million years. OXT’s fundamental role lies in reproduction and parenting ...
Epigenetic regulation of CD14 in TRIF pathway in pulmonary alveolar macrophages of German Landrace pigs
(2016-05-24)
Diseases of the respiratory system are a main problem in pig production. Pulmonary alveolar macrophages (PAMs) are key players to defend these respiratory diseases like lung inflammation caused by bacterial infection. ...
Metabarcoding Invertebrate Communities in a Natural Park: From Methods to Diversity Patterns
(2021-02-22)
Biodiversity is worldwide suffering from a dramatic decline, whose underlying causes are still fairly unknown. The scientific investigation and identification of potential drivers of biodiversity loss are strongly hampered ...
Ultrastructure, Formation and Evolution of Chaetae in Annelids
(2016-02-02)
Annelid systematics has been quite unstable over the past century. Especially, with the introduction of molecular techniques to unravel phylogenetic relationships, previously established morphology-based phylogenetic trees ...
Evolution of DNA methylation in insects
(2021-05-21)
DNA methylation, the addition of a methyl group (-CH3) to a genomic cytosine by a DNA methyltransferase, is the most thoroughly studied epigenetic modification across eukaryotes. Functionally, it is associated with the ...
Wahrnehmung von Wirbelstraßen bei Fischen der Familien Cyprinidae und Salmonidae
(2013-01-10)
In der vorliegenden Arbeit wurden erstmals Fische aus unterschiedlichen Lebensräumen auf komplexe hydrodynamische Reize im Fließwasser konditioniert. Hierzu wurden Kármánsche Wirbelstraßen verschiedener Wirbelablösefrequenzen ...
