Seasonal variations of sperm freezability associated with testicular germinal epithelium changes in domestic (Ovis aries) and wild (Ovis musimon) rams
(2019-06-11)
The aim of this study was to examine ovine sperm cryoresistance during the rutting season (RS) and its association with sperm head area and seminiferous epithelium proliferation. Small ruminants show fluctuating testosterone ...
Management support by optimization-based trade-off analysis: the example of biodiesel crop production
(2014)
Modeling in decision support applications has often been used to compare outcomes between alternative scenarios of decision options. The introduction of optimization methods enable the comparison of a very large number of ...
One-Time Acidification of Slurry: What Is the Most Effective Acid and Treatment Strategy?
(2021-06-28)
Acidification of slurry is a common practice to reduce ammonia and methane emissions.
Sulfuric acid is usually used for this process. However, this has been criticized due to the high sulfur
input into soils. Therefore, ...
Heating Performance and Ammonia Removal of a Single-Stage Bioscrubber Pilot Plant with Integrated Heat Exchanger under Field Conditions
(2021-10-10)
In this study, biological exhaust air treatment was combined with a recuperative heat exchanger in one process stage. The aim of this plant development and testing is not only to reduce ammonia from the exhaust air of pig ...
Glucocorticoids in relation to behavior, morphology, and physiology as proxy indicators for the assessment of animal welfare: A systematic mapping review
(2023-01-06)
Translating theoretical concepts of animal welfare into quantitative assessment protocols is an ongoing challenge. Glucocorticoids (GCs) are frequently used as physiological measure in welfare assessment. The interpretation ...
Triggering cognitive dissonance with textual information and images: Data from three experiments with meat-eaters
(2023-04-05)

Rural livelihoods, community-based conservation, and human–wildlife conflict: Scope for synergies?
(2022-08-01)
Halting biodiversity loss is a major contemporary challenge. Nature protection can help conserve biodiversity, but increasing wildlife numbers inside protected areas and shrinking habitats intensify interactions between ...
Recovering from Financial Implications of Flood Impacts: The Role of Risk Transfer in the West African Context
(2022-07-10)
In many West African river basins, households regularly experience floods and the associated impacts. In the absence of widely accessible formal risk transfer mechanisms (e.g., insurance), households often have to cope ...
Vegetation diversity in East African wetlands: Cocktail algorithms supported by a vegetation-plot database
(2022-12-08)
Aims: Wetlands in East Africa are important ecosystems for biodiversity conservation and ecosystem service provisioning, yet threatened by degradation and conversion into croplands. Conservation and land use management ...
