A Field Evaluation of the Efficacy of Milorganite as a Repellent for Non-Venomous Rat Snakes (Elaphe obsolete)

The objective of this study was to evaluate the efficacy of Milorganite® as a repellent for rat snakes. Milorganite® is the bio solids by-product left from the activated sludge process from the Milwaukee Metropolitan Sewer District. During 3, 7-day release periods, 5-6 mature rat snakes were placed within a 0.1ha plastic fence enclosure intended to impede escape. The enclosure contained natural and artificial hides and water. Snakes were fitted with an externally attached radio transmitter with location of each snake determined 3 times per day by radio telemetry and visual confirmation. During the first 2, 7-day period, with no Milorganite® treatment, snakes were contained within the enclosure for a similar (p\u3e0.05) duration of 9.1h±1.8 and 9.4h±1.8 respectively, before escaping. Prior to release of snakes in period 3, a total of 907.2g of Milorganite® was applied by hand in a 20cm width strip along the interior perimeter of the enclosure fence. During period 3, 6 snakes were maintained within the enclosure longer (p\u3c 0.005) compared to periods 1 and 2, with an average containment time of 23.5h/day±0.5. Total snake-hours that animals were maintained in the enclosure was higher (p\u3c0.005) during the Milorganite® treatment (164.0h±1.4) compared to non-treated period 1 (64.0h±1.8) or period 2 (66.0h±9.0). All snakes remained within the enclosure throughout the 7-day treatment period. One snake died on day 6, posttreatment from unknown causes. Results of this study suggest Milorganite® was effective as a repellent for the rat snake under these experimental conditions

Comparison of a 2-Layer Electric Fence and a Single Strand Electric Fence in Mitigating Browsing of Impatiens by White-Tailed Deer

The objective of this study was to evaluate two electric fence configurations in minimizing damage to impatiens (Impatiens walleriana) by white-tailed deer (Odocoileus virginianus). Each of 3 sites consisted of 3 plots (3mx3m), containing 16, evenly spaced impatiens planted on the perimeter of each plot. Plots within each site had a control, single strand and 2-layered electric fence. Control plots had no fencing. Single strand plots had one electrified wire attached to posts at 40 cm height, surrounding the plot. Two-layered electric fence had energized wire attached to posts at 25 cm and 60 cm height, on the perimeter of the plot. A second, single electrified wire was attached to posts at 25 cm height, 1 m to the exterior of the two strand fence. Eight plants within each plot was photographed weekly for 3-weeks. The percentage of total pixels containing plant material in each photo was used to determine changes in plant growth. The percentage of pixels containing impatiens plants was lower (

Field Evaluation of Two External Attachment Location of Radio Transmitters on Non-Venomous Rat Snakes (elaphe obsolete)

The objective of this study was to determine the effectiveness of external attachment of radio transmitters at one of two locations on mature rat snakes (Elaphe obsolete). Transmitters were attached to mature snakes (n = 10; 136.7cm ± 6.4) on either the ventral surface (n = 5) or dorsal-lateral surface of the rib cage (n = 5), approximately 25cm cranially to the cloaca. Transmitters (18mm × 8mm × 2mm) were attached by one drop of acrylamide gel glue to the adhering side of camouflage duct tape (20cm × 30mm), a single drop of glue on the exposed side of the transmitter, and secured by wrapping the tape to the snake’s body with the transmitter in the appropriate location. A second piece of duct tape (20cm × 40mm) overlapped and secured the first piece of tape with the transmitter. Snakes were placed in a 0.1ha plastic fence enclosure, (128.5cm ± 0.5 height, and 17.1° ± 0.5 inward slope) in an unimproved pasture with numerous hides, water and food. Snakes (n = 4) shed their skin and the transmitter, within 6- 17d post-attachment (11.7d ± 2.4). Snakes (n = 4) escaping the enclosure and not located, ranged from 1- 21d post-attachment, (12.3d ± 4.7). There was no difference (p \u3e 0.05) in functional days snakes were located by radio telemetry due to attachment site or sex. Transmitter reception distance was typically \u3c 50m and often problematic. Results of this study suggest that the location of external attachment of transmitters had no influence on duration of effectiveness. However, shedding and limited telemetry range under these conditions should be considered to determine if the methodology is appropriate for the desired objectives

The Prevalence of Two Common Internal Parasites in White-tailed Deer With and Without Significant Interaction With Domestic Sheep

The objective of this study was to evaluate the prevalence of two internal parasites (strongylate nematodes and Nematodirus spp.) in white-tailed deer (Odocoileus virginianus) sharing a home range with domestic sheep (Ovis aries), compared to deer likely having minimal contact with sheep. Fecal samples were collected from sheep (n=75), deer (n=99) within 300m of the sheep center, and deer (n=98) located 1.3km away from the livestock center, over a 7-week period during the summer. Sheep had the highest (p\u3c.001) number of strongylate eggs (1,212.7 ± 2.8/g) compared to deer near the livestock facility (13.9 ± 0.3/g) or deer located away from the sheep center (18.3 ± 0.3/g). Eggs of Nematodirus spp. were greater (p\u3c.001) in sheep (33.7 ± 0.5/g) compared to deer samples collected near the sheep center (5.1 ± 0.2/g) and deer away from the sheep facility (3.0 ± 0.1/g). Additionally, strongyle and Nematodirus spp. egg counts were different (p\u3c0.001) in the fecal samples collected from deer residing closer to the sheep facility compared to those located farther away. Results of this study suggest the interactions of white-tailed deer and domestic sheep does not influence the prevalence of these internal parasites within the deer

Physics case for an LHCb Upgrade II - Opportunities in flavour physics, and beyond, in the HL-LHC era

The LHCb Upgrade II will fully exploit the flavour-physics opportunities of the HL-LHC, and study additional physics topics that take advantage of the forward acceptance of the LHCb spectrometer. The LHCb Upgrade I will begin operation in 2020. Consolidation will occur, and modest enhancements of the Upgrade I detector will be installed, in Long Shutdown 3 of the LHC (2025) and these are discussed here. The main Upgrade II detector will be installed in long shutdown 4 of the LHC (2030) and will build on the strengths of the current LHCb experiment and the Upgrade I. It will operate at a luminosity up to 2×1034 cm−2s−1, ten times that of the Upgrade I detector. New detector components will improve the intrinsic performance of the experiment in certain key areas. An Expression Of Interest proposing Upgrade II was submitted in February 2017. The physics case for the Upgrade II is presented here in more depth. CP-violating phases will be measured with precisions unattainable at any other envisaged facility. The experiment will probe b → sl+l−and b → dl+l− transitions in both muon and electron decays in modes not accessible at Upgrade I. Minimal flavour violation will be tested with a precision measurement of the ratio of B(B0 → μ+μ−)/B(Bs → μ+μ−). Probing charm CP violation at the 10−5 level may result in its long sought discovery. Major advances in hadron spectroscopy will be possible, which will be powerful probes of low energy QCD. Upgrade II potentially will have the highest sensitivity of all the LHC experiments on the Higgs to charm-quark couplings. Generically, the new physics mass scale probed, for fixed couplings, will almost double compared with the pre-HL-LHC era; this extended reach for flavour physics is similar to that which would be achieved by the HE-LHC proposal for the energy frontier

LHCb upgrade software and computing : technical design report

This document reports the Research and Development activities that are carried out in the software and computing domains in view of the upgrade of the LHCb experiment. The implementation of a full software trigger implies major changes in the core software framework, in the event data model, and in the reconstruction algorithms. The increase of the data volumes for both real and simulated datasets requires a corresponding scaling of the distributed computing infrastructure. An implementation plan in both domains is presented, together with a risk assessment analysis

Anatomy of a Snake Fence Intended to Prevent Escape of Non-Venomous Rat Snakes (Elaphe obsolete) from an Enclosure

We constructed a fence enclosure with the objective of preventing escape of rat snakes (Elaphe obsolete) as part of a repellent study. A 25cm trench was dug in a 30m × 30m square (0.1ha) in an unimproved pasture. Wood posts (8.9cm × 8.9cm × 2.0m) were secured on corners and at 15m intervals between each corner at an average height of 128.5cm ± 0.5 height with an inward slope of 17.1o ± 0.5. Steel T-posts (2.0m) were erected to a similar height and angle at 4m intervals between wood posts and fitted with plastic insulated caps. Three strands of 17-gauge wire were secured to the top, middle and 10cm above the ground of each post. Plastic sheeting (3.04m × 30.4m × 4mm) was draped over the suspended wires with the bottom 25cm secured within the trench with dirt. All overlapping seams of plastic were secured with polypropylene tape. A single strand of 17-gauge electric fence wire and a strand of electric polyfence tape were attached by duct tape to the top of the inside of the plastic fence. An additional strand of electric polyfence was attached by duct tape to the plastic 20cm above the ground. A loop of the electric polytape was also attached in each corner and connected to the wire and polytape on the top and lower strand of polytape. The electric fence strand and all polytape was energized by a solar powered charger with an output \u3e 5000v. During two releases of 5 mature rat snakes (n = 10; 136.7cm ± 6.4), containment within the enclosure was similar (p \u3e 0.05), and limited to 9.1h ± 1.8 and 9.4h ± 1.8 respectively. Video analysis indicated snakes were climbing the electric charged polyfence tape and escaping over the fence without evidence of receiving an electric shock. This fence design was not sufficient to maintain mature rat snakes
