And Migration

Moult of feathers entails considerable physiological and energetic costs to an avian organism. Even under favourable feeding conditions, endogenous body stores and energy reserves of moulting birds are usually severely depleted. Thus, most species of birds separate moult from other energy-demanding activities, such as migration or reproduction. Common snipeGallinago gallinagois an exception, as during the first autumn migration many young snipe initiate the post-juvenile moult, which includes replacement of body feathers, lesser and median wing coverts, tertials, and rectrices. Here, we evaluated moult-related changes in blood plasma biochemistry of the common snipe during a period of serious trade-off in energy allocation between moult and migration. For this purpose, concentrations of basic metabolites in plasma were evaluated in more than 500 young snipe migrating through Central Europe. We found significant changes in the plasma concentrations of total protein, triglyceride and glucose over the course of moult, while the concentrations of uric acid and albumin did not change. Total protein concentration increased significantly in the initial stage of moult, probably as a result of increased production of keratin, but it decreased to the pre-moult level at the advanced stage of moult. Plasma triglyceride concentration decreased during the period of tertial and rectrice moult, which reflected depletion of endogenous fat reserves. By contrast, glucose concentration increased steadily during the course of moult, which could be caused by increased catabolism of triglycerides (via gluconeogenesis) or, alternatively, due to increased glucocorticoids as a stress response. Our results suggest that physiological changes associated with moult may be considered important determinants of the low pace of migration typical of the common snipe.

Abstract Background Acute Respiratory Distress Syndrome (ARDS) is associated with increased pulmonaryvascular permeability. In the lung, transient receptor potential vanilloid 4 (TRPV4), a Ca2+-permeable cation channel, is a regulator of endothelial permeability and pulmonary edema. We performed a Phase I, placebocontrolled, doubleblind, randomized, parallel group, proofofmechanism study to investigate the effects of TRPV4 channel blocker, GSK2798745, on pulmonaryvascular barrier permeability using a model of lipopolysaccharide (LPS)induced lung inflammation. Methods Healthy participants were randomized 1:1 to receive 2 single doses of GSK2798745 or placebo, 12 hours apart. Two hours after the first dose, participants underwent bronchoscopy and segmental LPS instillation. Total protein concentration and neutrophil counts were measured in bronchoalveolar lavage (BAL) samples collected before and 24 hours after LPS challenge, as markers of barrier permeability and inflammation, respectively. The primary endpoint was baseline adjusted total protein concentration in BAL at 24 hours after LPS challenge. A Bayesian framework was used to estimate the posterior probability of any percentage reduction (GSK2798745 relative to placebo). Safety endpoints included the incidence of adverse events (AEs), vital signs, 12-lead electrocardiogram, clinical laboratory and haematological evaluations, and spirometry. Results Forty-seven participants were dosed and 45 completed the study (22 on GSK2798745 and 23 on placebo). Overall, GSK2798745 was well tolerated. Small reductions in mean baseline adjusted BAL total protein (~ 9%) and neutrophils (~ 7%) in the LPS-challenged segment were observed in the GSK2798745 group compared with the placebo group; however, the reductions did not meet pre-specified success criteria of at least a 95% posterior probability that the percentage reduction in the mean 24hours post LPS BAL total protein level (GSK2798745 relative to placebo) exceeded zero. Median plasma concentrations of GSK2798745 were predicted to inhibit TRPV4 on lung vascular endothelial cells by ~ 7085% during the 24 hours after LPS challenge; median ureacorrected BAL concentrations of GSK2798745 were 3.0 to 8.7fold higher than those in plasma. Conclusions GSK2798745 did not affect segmental LPS-induced elevation of BAL total protein or neutrophils, despite blood and lung exposures that were predicted to be efficacious.

Based on the definition of 6 basic body types in the group, the family Cyclocoelidae is revised with the erection of Skrjabinocoelinae n. subf. and Szidatitreminae n. subf., and the resurrection of the subfamily Hyptiasminae. Subfamily keys and keys to genera that accommodate the original 3 subfamilies (Cyclocoelinae, Ophthalmophaginae, and Haematotrephinae), the 3 additional subfamilies proposed, the 6 body types used in the revision, and the recently described genus Selfcoelum are provided. Morishitium texanense n. sp. is described from the common snipe, Gallinago gallinago, in Texas, U.S.A., the genus Neoallopyge is synonymized with Allopyge, and the genus Neohyptiasmus is synonymized with Morishitium.

Two mature worms of this species were recovered from the small intestine of a Common Snipe, Gallinago gallinago (Liun.), shot on a Cardiganshire moor in July 1935. Three mature worms were again obtained from a Common Snipe shot on the same moor in the third week of October 1936, just prior to the arrival of the migrant snipe.

1. Male and female Japanese quail (Coturnix coturnix japonica) were reared under short daily photoperiods (8 h light–16 h dark) to inhibit sexual development with free access to food and water. Blood was sampled at frequent intervals for 13 weeks from hatching in order to monitor the developmental changes in plasma concentrations of the two proteins which are important in the transport of retinol, retinol-binding protein (RBP) and thyroxine-binding prealbumin (TBPA).2. Measurements of body-weight, blood packed cell volume and plasma total protein concentration showed that the birds had a normal pattern of growth and haematological development. Plasma concentrations of TBPA, total immunoreactive RBP (IRBP) and holoRBP were 220, 60 and 45 μg/ml respectively in 1-d-old quail and rose to 430, 165 and 140 μg/ml at 14 d of age, which was 10 d after the corresponding change in total protein. Neither RBP nor TBPA concentrations were significantly different between the sexes during the 13 weeks, but there were minor fluctuations in concentration within relatively narrow limits.

The regularization of the wintering status of the Jack Snipe (Lymnocryptes minimus) in NW Italy has been confirmed for the first time within the heathland of the “Baraggia di Candelo Natural Reserve” (Piedmont, Biella). Regular monitoring from winter 2009/2010 to winter 2015/2016 allowed to describe the phenology and the abundance of the species in the area comparing it with that of an ally species, the Common Snipe (Gallinago gallinago). A maximum count of 6 birds during winter and at least 13 individuals during the spring migration were recorded. The species was more abundant during the second 10-day period of November and the first 10-day period of March. Jack Snipe outnumber the Common Snipe throughout the period they were censused.
