Abstract	For ruminants, grazing and ruminating activities are essential in nutrient capture and ultimately animal performance however these activities can demand significant time and energy. This study evaluated the effect of three different pasture allocation frequencies (PAF’s; 12, 24 and 36 h) on the feeding behaviour of grazing dairy cows. Eighty-seven spring calving dairy cows were divided into three treatments. Animals were rotationally grazed with fixed paddock sizes of 0.14 ha, 0.28 ha and 0.42 ha paddocks for the 12 h, 24 h and 36 h treatments, respectively. Animals (14 per treatment) were fitted with behaviour halters that monitored feeding activity. Diurnal feeding patterns were evident for all animals irrespective of PAF, concentrating the majority of grazing during daytime (90%) and ruminating activity during night (73%). Treatment significantly affected feeding behavior patterns. Peak grazing activity coincided with fresh pasture allocation in the 12 h and 24 h treatments. In the 36 h treatment, grazing was more evenly distributed over each 24 h period with peak grazing activity witnessed daily between 17:00 and 19:00 regardless of fresh pasture allocation, suggesting lack of anticipation of fresh feed delivery. In the 12 h treatment primiparous animals exhibited greater grazing and ruminating activity relative to multiparous animals in the 12 h treatment highlighting the impact of competition for resources within each feed on lower dominance animals.

Abstract	Bulk production of medium-chain carboxylates (MCCs) with 6-12 carbon atoms is of great interest to biotechnology. Open cultures (e.g., reactor microbiomes) have been utilized to generate MCCs in bioreactors. When in-line MCC extraction and prevention of product inhibition is required, the bioreactors have been operated at mildly acidic pH (5.0-5.5). However, model chain-elongating bacteria grow optimally at neutral pH values. Here, we isolated a chain-elongating bacterium (strain 7D4C2) that grows at mildly acidic pH. We studied its metabolism and compared its whole genome and the reverse β-oxidation (rBOX) genes to other bacteria. Strain 7D4C2 produces lactate, acetate,

Abstract	Bacterial viruses contribute to the dynamics of the microbiome communities, as they are involved in the horizontal gene transfer. Previously we studied changes in the gut microbiome of the two healthy individuals over the course of a 6-days antibiotics treatment and subsequent 28 days recovery time (Willmann et al., 2015). Now, from the same samples, the virus-like particles were isolated and sequenced. As the phage sequences are currently poorly represented in reference databases, the reads had to be assembled, annotated and their abundance had to be evaluated via reads mapping. We analyzed and compared patterns of changes in abundance of the phage scaffolds and scaffolds with antibiotics resistant genes, in both phage and whole-genome metagenomic sets. We observed an increase in abundance of scaffolds carrying antibiotic-resistant genes in response to the treatment.

Abstract	Parasitic helminths secrete extracellular vesicles (EVs) which have potent immunomodulatory effects. Whilst the cargo of EVs has been characterised for many species, we know little about the mechanisms that govern their biogenesis and release. Using antibodies raised against a panel of Fasciola hepatica EV (FhEV) marker proteins, we have identified multiple sites of EV production in the parasite. Discrete immunofluorescence patterns were observed within the gastrodermal cells and tegumental syncytium for different marker proteins whilst the protonephridial (excretory) system and parenchymal-type 2 cells were identified as additional sites of production (or transit) of FhEVs. Ligation was used to mechanically block the oral sucker, excretory pore, or both, to determine the effect on FhEV release from live adult flukes in vitro. This revealed that FhEVs are predominately derived from the gut, whilst the tegument releases EVs to a lesser extent. The data also suggest that the protonephridial system contributes to the small (120 K) EV sub-population. Sphingomyelinase (SMase) activity is a key driver of EV biogenesis in mammalian cells and we have previously identified SMases in FhEVs by mass spectrometry. SMase activity associated with isolated FhEVs was susceptible to the chemical inhibitor GW4869 and treatment of adult flukes with GW4869 led to a significant reduction in 120 K EV release in vitro, suggesting that a ceramide-dependent mechanism could drive 120 K EV formation. In contrast, the release of the larger 15 K EVs was only moderately impacted, indicating that they form independently of SMase activity. Ultrastructural observation of GW4869-treated F. hepatica tissue showed severe disruption to the parenchyma and vacuolation of the tegument, gastrodermal cells and epithelial lining of the excretory ducts. This work establishes that targeted disruption of EV biogenesis and release in helminths is possible, and provides proof-of-concept for future studies investigating EV secretion as a target for parasite control.

Article: Channel Response and Reservoir Delta Evolution From Source to Sink Following an Extreme Flood

Abstract	Disturbances such as floods, fires, and mass movements introduce large volumes of sediment into fluvial systems. Tracking the movement of disturbance‐generated sediment provides insight into the processes of fluvial system response. Few studies document a post‐disturbance response that explicitly links channel change to evolution of a reservoir delta. We exploit the tight coupling in a sediment source‐to‐sink analysis of flood deposits over 6 years. Within the first year after the flood, the channel incised 1.5 m and widened 10 m. Limited channel morphologic change thereafter is attributed to bed armoring. Morphodynamic modeling of the channel predicted transport of Radio‐Frequency Identification‐tagged clasts from which we infer a discharge threshold of >14 m³/s for future geomorphic adjustments. Post‐flood discharges and reservoir drawdowns deposited 3 times the volume of sediment in the delta than was deposited during the flood and prograded the delta 200 m. Overall system response followed a characteristic sediment decay flux. Despite the sediment flux decline, comparable rates of delta progradation occurred due to reservoir drawdowns that shifted the sediment source from the channel to incision of the delta. Thus, the delta evolved via distinct processes based on sediment source and reservoir level: (a) aggradation of the delta topset and progradation of the Gilbert‐type clinoform when sediment is sourced from the channel during years when reservoir level fluctuated seasonally; and (b) delta progradation through incision of the delta topset during reservoir drawdowns. Our results reveal a genetic relationship between post‐disturbance channel and delta evolution.

Abstract	Pleural tuberculosis is an infrequent cause of respiratory illness in Europe and usually presents unilaterally. We present the case of a young, immunocompetent sailor from the Phillippines, who presented with bilateral pleural fluid caused by Mycobacterium tuberculosis infection in the Netherlands.

Abstract	To assess the effect of hair type on the heat stress response, 20 Criollo Limonero heifers with slick (n = 11) or normal hair (n = 9) were studied. Under a high temperature-humidity index (THI) environment, heat stress response was assessed through physiological variables that included respiration rate (RR), heart rate (HR), ruminal frequency (RMF), rectal temperature (RT), saliva pH (SPH), and lymphocyte count (LC) in the morning (5:00 AM, 27.4 °C, 64% relative humidity, THI = 77) and afternoon (1:00 PM, 34.5 °C, 70% relative humidity, THI = 88). A case-control study using a split plot design was used. Data were analyzed using ANOVA (PROC MIXED SAS 2010) and a statistical model comprising the fixed effects of hair length, sampling hour, interaction of hair length by sampling hour, and the random effect of animal nested within hair type on physiological variables associated with heat stress response. Sampling hour influenced (P < 0.0001) RR, RT, and (P < 0.003) SPH. Hair length influenced RR (P < 0.01) and RT (P < 0.04) and tended to influence LC (P < 0.07). The interaction of sampling hour by hair influenced RR (P < 0.04), RT (P < 0.0002), and both SPH and LC (P < 0.05). During afternoon hours, slick-haired heifers had lower values for RR (81 ± 4.2 vs 102 ± 4.7 bpm; P < 0.01), RT (39.5 ± 0.1 vs 40.3 ± 0.1 C°; P < 0.002), and LC (60 ± 3.2 vs 72.3 ± 3.6; P < 0.09) than normal-haired heifers. In normal-haired heifers, SPH increased during afternoon compared to morning-hours (8.66 ± 0.1 vs 9.11 ± 0.1; P < 0.04). It was concluded that slick-coated heifers exhibited an enhanced capability to cope with heat stress compared to normal-haired heifers likely due to an enhanced capacity for heat dissipation.
