Carbon Stocks and Ecological Implications of Open Spaces: A Case Study in Recife - Brazil
Jende, Oliver (2011-07-14)The aim of this work is to evaluate the ecological implications of the whole range of urban and rural land use systems from a common perspective focused on carbon stocks and land use change (LUC) in urbanizing areas of ... -
Cellular energy supply and aging in dairy cows: Characterization of different physiological states and impact of diet-induced over-condition
Laubenthal, Lilian (2015-09-24)Lactation in dairy cows is accompanied by dramatic changes in energy balance and thus requires the continued adaption of the key organs, namely adipose tissue (AT), liver, and mammary gland to the varying conditions. The ... -
Challenges and opportunities of using ecological and remote sensing variables for crop pest and disease mapping
Kyalo, Richard (2019-07-15)Crop pest and diseases are responsible for major economic losses in the agricultural systems in Africa resulting in food insecurity. Potential yield losses for major crops across Africa are mainly caused by pests and ... -
Challenges related to statistical methods and sensor systems for the daily prediction of health disorders in individual dairy cows
Post, Christian (2023-02-02)The use of digital support systems has become a standard in dairy farming, and significant effort has been made to detect individual animals that are in need for a treatment by using sensor data. However, developing systems ... -
Changes of inner teat morphology caused by the milking process and by incomplete milking during dry-off as assessed by innovative technologies
Martin, Lisett Marie (2020-03-03)In dairy farming, the timing of the lactation cycle and the way of milk removal differ considerably from the natural conditions. Ensuring good health and wellbeing of farm animals is of great interest from both an economic ... -
Characterisation of fitness parameters and population dynamics of Botrytis cinerea for the development of fungicide resistance management strategies in grapevine
Derpmann, Jürgen (2014-03-18)Gray mold caused by the fungus<i>Botrytis cinerea</i> is an economically important disease in grapevine. The pathogen has a high tendency to become resistant to frequently applied systemic fungicides. Only a few years after ... -
Characterisation of the effect of redox potential on the emission of greenhouse gases using wireless sensing techniques
Wang, Jihuan (2021-11-18)Soils act as both a source and sink of greenhouse gases (GHGs) and are widely considered to contribute to global warming. Soil N<sub>2</sub>O emissions originate from microbial nitrification and denitrification processes. ... -
Characterization of adiponectin at different physiological states in cattle based on an in-house developed immunological assay for bovine adiponectin
Singh, Shiva Pratap (2014-02-07)Adipose tissue (AT), through secretion of adipokines, plays a central role in regulating metabolism. Adiponectin is one of the most abundant adipokines and is linked with several physiological mechanisms such as insulin ... -
Characterization of insecticide resistance in Hemipteran crop pests with special reference to aphids and whiteflies
Müller, Viola (2024-01-26)Agriculture faces enormous challenges: In addition to the increasing demand for agricultural products with less available agricultural landscapes, there is a need to protect the environment and biodiversity and to minimize ... -
Characterization of insulin sensitivity and inflammation related factors in dairy cows receiving conjugated linoleic acids (CLA) or a control fat supplement during lactation
Saremi, Behnam (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 ... -
Characterization of mechanisms of resistance in Spodoptera frugiperda to synthetic insecticides and insecticidal proteins
Duarte Boaventura, Debora (2021-03-18)Fall armyworm (FAW), Spodoptera frugiperda(J.E. Smith), is a major lepidopteran pest of maize in the American continent butitis now present in 107 countries worldwide. The control of FAW has relied mainly on the ... -
Characterization of porcine milk exosomes from different stages of lactation
Furioso Ferreira, Rafaela (2023-05-11)Exosomes are membranous vesicles considered major players in cell-cell communication. Milk provides adequate nutrition, transfers immunity, and promotes neonate development, and milk exosomes are suggested to have a key ... -
