Role of termites for the distribution patterns of carbon and phosphorus fractions and the genesis of tropical soils, Brazil
(2012-07-27)
Tropical soil fertility is limited by low phosphorus (P) availability, limited accumulation of organic matter and by advanced stages of pedogenesis. Termites are well-known soil-engineers, which accumulate clay, organic ......
Die Bedeutung von Termiten für die Verteilungsmuster von Kohlenstoff- und Phosphor-Fraktionen sowie die Genese Tropischer Böden, Brasilien
Die Bodenfruchtbarkeit in den Tropen ist durch eine geringe ......
A fertilidade dos solos tropicais é limitada pela baixa disponibilidade de fósforo, a falta de acumulação de matéria orgânica, e por estados avançados de pedogênese. Os térmitas ou cupins são bem-conhecidos 'engenheiros ......

Identification of candidate genes for boar taint using RNA deep sequencing
(2013-07-11)
The aim of the present study was to identify candidate genes for boar taint using RNA deep sequencing. For this purpose, two experiments were performed. In the first experiment, transcriptome profiling was analyzed in the ...
Characterization of insulin sensitivity and inflammation related factors in dairy cows receiving conjugated linoleic acids (CLA) or a control fat supplement during lactation
(2013-08-20)
With the onset of lactation, dairy cows have to mobilize body reserves, mainly body fat, to cover the output of energy via milk. The homeorhetic metabolic adaptation to the needs of milk production is accomplished through ...
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 ...
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. ...
Zur tierökologischen Bedeutung der Elsbeere (Sorbus torminalis L. CRANTZ)
(2018-06-14)
Mit der vorliegenden Dissertation soll das ökologische Beziehungsgeflecht der Elsbeere (Sorbus torminalis) erfasst werden, einer in Deutschland seltenen, in zerstreuten, kleinen Populationen vorkommenden Baumart (Fam. ......

Einfluss der Bewirtschaftungsintensität und Landschaftsstruktur auf die Diversität der Saltatoria und Hymenoptera (Bombus) von Mittelgebirgsgrünland
(2018-11-27)
Grünland ist ein prägendes Element der Agrarlandschaft und zentraler Baustein der multifunktionalen Landwirtschaft. Unter anderem leistet es einen herausragenden Beitrag zur Erhaltung der biologischen Vielfalt. Die Quantität ...
Lucerne silage for high yielding dairy cows: evaluation of the nutritional value using chemical and in vivo methods
(2018-02-07)
Lucerne has a high yield potential and can provide ruminants with significant amounts of energy and protein as well as having excellent structural properties. This thesis focussed on the response (dry matter intake (DMI), ......
