Melding Wildlife Surveys to Improve Conservation Inference

Integrated models are a popular tool for analyzing species of conservation concern. Species of conservation concern are often monitored by multiple entities that generate several datasets. Individually, these datasets may be insufficient for guiding management due to low spatio-temporal resolution, biased sampling, or large observational uncertainty. Integrated models provide an approach for assimilating multiple datasets in a coherent framework that can compensate for these deficiencies. While conventional integrated models have been used to assimilate count data with surveys of survival, fecundity, and harvest, they can also assimilate ecological surveys that have differing spatio-temporal regions and observational uncertainties. Motivated by independent aerial and ground surveys of lesser prairie-chicken abundance, we developed an integrated modeling approach that assimilates density estimates derived from surveys with distinct sources of observational error into a joint framework that provides shared inference on spatio-temporal trends. For implementation, we model these data using a Bayesian Markov melding approach and apply several data augmentation strategies for efficient sampling. Our integrated model decreased uncertainty in annual density estimates, facilitated prediction at unsampled regions, and quantified the inferential cost associated with reduced survey effort.Comment: 22 pages; 5 figures, 1 table, submitted to Biometric

Laser Treatment of Darier Disease: Report of Two Cases and Systematic Review of the Literature

Introduction: Darier Disease (DD) is a chronic disease with high morbidity and limited treatment options. Laser efficacy in the treatment of DD remains understudied.Methods: A literature search conducted between 07/21/2017 and 05/05/2018 identified all original cases of DD treated with laser therapy.Results: Outcomes from 24 patients were reviewed, 22 patients were identified in the literature and 2 cases are included from our institution. Five types of lasers were identified [CO2 laser, Er:YAG laser, pulse dye laser [PDL], diode laser, erbium-doped fiber laser], with CO2 (46%) and PDL (42%) being the most common. Seventy-nine percent of patients were treated with more than one procedure (average, 3 procedures). The estimated body surface treated with each session ranged from 5%-50%. The most common adverse events came from CO2 and Er: YAG lasers and included dyspigmentation, pain, and post-laser erythema and edema. The time to response (mode, 1 month) was only reported in half of the studies.Conclusion: Laser treatments appear to be a promising alternative to standardized therapies in DD

Repro Money: An Extension Program to Improve Dairy Farm Reproductive Performance

A farmer-directed, team-based Extension program (Repro Money) was developed and executed by the University of Wisconsin–Madison Department of Dairy Science in collaboration with University of Wisconsin–Extension. The goal of the Repro Money program was to help Wisconsin dairy farmers increase reproductive performance and profitability through identification of areas for improvement and implementation of action plans. For the 40 Wisconsin dairy farms that completed the Repro Money program, mean 21-day pregnancy rate increased by 2 percentage points, which was estimated to result in an economic net gain of $31 per cow per year. Extension professionals can apply similar team-based programs to tackle multifaceted, interrelated problems that may be only partially addressed by other, more traditional programming

Anisotropic distribution functions for spherical galaxies

A method is presented for finding anisotropic distribution functions for stellar systems with known, spherically symmetric, densities, which depends only on the two classical integrals of the energy and the magnitude of the angular momentum. It requires the density to be expressed as a sum of products of functions of the potential and of the radial coordinate. The solution corresponding to this type of density is in turn a sum of products of functions of the energy and of the magnitude of the angular momentum. The products of the density and its radial and transverse velocity dispersions can be also expressed as a sum of products of functions of the potential and of the radial coordinate. Several examples are given, including some of new anisotropic distribution functions. This device can be extended further to the related problem of finding two-integral distribution functions for axisymmetric galaxies.Comment: 5 figure

A Highly Contiguous and Annotated Genome Assembly of the Lesser Prairie-Chicken (Tympanuchus pallidicinctus)

Article asserts that the Lesser Prairie-Chicken (Tympanuchus pallidicinctus; LEPC) is an iconic North American prairie grouse, renowned for ornate and spectacular breeding season displays, a species that has been declining in population across much of its historical range, with corresponding precipitous declines in contemporary population abundance, largely due to climatic and anthropogenic factors. The authors describe an annotated reference genome that was generated from a LEPC sample collected from the southern DPS

From Rapid Place Learning to Behavioral Performance: A Key Role for the Intermediate Hippocampus

Rapid place encoding by hippocampal neurons, as reflected by place-related firing, has been intensely studied, whereas the substrates that translate hippocampal place codes into behavior have received little attention. A key point relevant to this translation is that hippocampal organization is characterized by functional-anatomical gradients along the septotemporal axis: Whereas the ability of hippocampal neurons to encode accurate place information declines from the septal to temporal end, hippocampal connectivity to prefrontal and subcortical sites that might relate such place information to behavioral-control processes shows an opposite gradient. We examined in rats the impact of selective lesions to relevant parts of the hippocampus on behavioral tests requiring place learning (watermaze procedures) and on in vivo electrophysiological models of hippocampal encoding (long-term potentiation [LTP], place cells). We found that the intermediate hippocampus is necessary and largely sufficient for behavioral performance based on rapid place learning. In contrast, a residual septal pole of the hippocampus, although displaying intact electrophysiological indices of rapid information encoding (LTP, precise place-related firing, and rapid remapping), failed to sustain watermaze performance based on rapid place learning. These data highlight the important distinction between hippocampal encoding and the behavioral performance based on such encoding, and suggest that the intermediate hippocampus, where substrates of rapid accurate place encoding converge with links to behavioral control, is critical to translate rapid (one-trial) place learning into navigational performance

Supplement: "Localization and broadband follow-up of the gravitational-wave transient GW150914" (2016, ApJL, 826, L13)

This Supplement provides supporting material for Abbott et al. (2016a). We briefly summarize past electromagnetic (EM) follow-up efforts as well as the organization and policy of the current EM follow-up program. We compare the four probability sky maps produced for the gravitational-wave transient GW150914, and provide additional details of the EM follow-up observations that were performed in the different bands

Localization and broadband follow-up of the gravitational-wave transient GW150914

A gravitational-wave (GW) transient was identified in data recorded by the Advanced Laser Interferometer Gravitational-wave Observatory (LIGO) detectors on 2015 September 14. The event, initially designated G184098 and later given the name GW150914, is described in detail elsewhere. By prior arrangement, preliminary estimates of the time, significance, and sky location of the event were shared with 63 teams of observers covering radio, optical, near-infrared, X-ray, and gamma-ray wavelengths with ground- and space-based facilities. In this Letter we describe the low-latency analysis of the GW data and present the sky localization of the first observed compact binary merger. We summarize the follow-up observations reported by 25 teams via private Gamma-ray Coordinates Network circulars, giving an overview of the participating facilities, the GW sky localization coverage, the timeline, and depth of the observations. As this event turned out to be a binary black hole merger, there is little expectation of a detectable electromagnetic (EM) signature. Nevertheless, this first broadband campaign to search for a counterpart of an Advanced LIGO source represents a milestone and highlights the broad capabilities of the transient astronomy community and the observing strategies that have been developed to pursue neutron star binary merger events. Detailed investigations of the EM data and results of the EM follow-up campaign are being disseminated in papers by the individual teams
