Predicting fiber content in herbivore fecal samples using a multispecies NIRS model.

Fiber is essential for rumen health, microbial fermentation, and the energy supply of herbivores. Even though the study of fecal fiber contents (neutral detergent fiber NDF, acid detergent fiber ADF, and acid detergent lignin ADL) using near-infrared reflectance spectroscopy (NIRS) has allowed investigating nutritional ecology of different herbivore species, NIRS calibrations are species-specific and require a large number of samples for predictions. A multispecies calibration would be an advantage since samples from different herbivores could be used to calibrate a model capable of predicting the fecal fiber content of other herbivores.

Combined effects of landscape fragmentation and sampling frequency of movement data on the assessment of landscape connectivity.

Background: Network theory is largely applied in real-world systems to assess landscape connectivity using empirical or theoretical networks. Empirical networks are usually built from discontinuous individual movement trajectories without knowing the effect of relocation frequency on the assessment of landscape connectivity while theoretical networks generally rely on simple movement rules. We investigated the combined effects of relocation sampling frequency and landscape fragmentation on the assessment of landscape connectivity using simulated trajectories and empirical high-resolution (1 Hz) trajectories of Alpine ibex (Capra ibex).

Prevalence of tick-borne pathogens in ticks collected from the wild mountain ungulates mouflon and chamois in 4 regions of France.

Ticks are major vectors of various pathogens of health importance, such as bacteria, viruses and parasites. The problems associated with ticks and vector-borne pathogens are increasing in mountain areas, particularly in connection with global climate change. We collected ticks (n = 2,081) from chamois and mouflon in 4 mountainous areas of France.

Experiences of parents and caretakers going through the consent process to perform minimally invasive tissue sampling (MITS) on their deceased children in Quelimane, Mozambique: A qualitative study.

Background: In Mozambique, the Countrywide Mortality Surveillance for Action (COMSA) Program implemented a child mortality surveillance to strengthen vital events registration (pregnancies, births, and deaths) and investigate causes of death using verbal autopsies. In Quelimane district, in addition to the abovementioned cause of death determination approaches, minimally invasive tissue sampling (MITS) was performed on deceased children <5years of age. This study focused on understanding deceased children parents' and caretakers' experiences of the consent process to perform MITS in order to contribute to the improvement of approaches to cause of death investigation and inform efforts to maximize acceptability of mortality surveillance activities.
