The Progression of Spring in Southeastern Iowa

Is this spring earlier or later than usual? When is the best time to plant? If the ground-hog comes out of his hole today will he see his shadow? Questions such as these have stimulated people to look for and record the occurrence of natural events either as hobbies, rules of thumb for farming or as methods of predicting and recording the arrival of spring. Natural events such as general thaw, leafing of trees and shrubs and plant-flowering have been used in the past by Jaques (1924, 1944), Dodd et al. (1934) and Hodson (1951). In many instances one biological event can be correlated with the occurrence of another natural event: the flowering of a plant with the arrival of a migratory bird or the advent of a destructive plant or animal species. This paper deals with the progression of spring in Henry County of southeastern Iowa. The first-bloom of a flower served as the gauge of seasonal progression. The study covered the period from 1946-1957 and included both native and cultivated plants which have been grown outdoors

A Morpho-molecular Perspective on the Diversity and Evolution of Spumellaria (Radiolaria)

Spumellaria (Radiolaria, Rhizaria) are holoplanktonic amoeboid protists, ubiquitous and abundant in the global ocean. Their silicified skeleton preserves very well in sediments, displaying an excellent fossil record extremely valuable for paleo-environmental reconstruction studies, from where most of their extant diversity and ecology have been inferred. This study represents a comprehensive classification of Spumellaria based on the combination of ribosomal taxonomic marker genes (rDNA) and morphological characteristics. In contrast to established taxonomic knowledge, we demonstrate that symmetry of the skeleton takes more importance than internal structures at high classification ranks. Such reconsideration allows gathering different morphologies with concentric structure and spherical or radial symmetry believed to belong to other Radiolaria orders from the fossil record, as for some Entactinaria families. Our calibrated molecular clock dates the origin of Spumellaria in the middle Cambrian (ca. 515 Ma), among the first radiolarian representatives in the fossil record. This study allows a direct connection between living specimens and extinct morphologies from the Cambrian, bringing both a standpoint for future molecular environmental surveys and a better understanding for paleo-environmental reconstruction analysis.

Considering the IDD Within the EU Legal Framework on ADR Systems

AbstractThis chapter will analyse the role of IDD as the new EU legal framework for enforcing consumer ADR system in the insurance sector. After a brief examination of the main EU initiatives aimed at promoting the use of ADR for consumer's disputes, it will consider the position of the IDD rules. Then, it will try to imagine the impact of the IDD framework on out-of-court redress for the insurance sector, with an overview of the main items that could be faced in the implementation of article 15 of the directive

Interaction of Climate Change with Effects of Conspecific and Heterospecific Density on Reproduction

We studied the relationship between temperature and the coexistence of great titParus majorand blue titCyanistes caeruleus, breeding in 75 study plots across Europe and North Africa. We expected an advance in laying date and a reduction in clutch size during warmer springs as a general response to climate warming and a delay in laying date and a reduction in clutch size during warmer winters due to density-dependent effects. As expected, as spring temperature increases laying date advances and as winter temperature increases clutch size is reduced in both species. Density of great tit affected the relationship between winter temperature and laying date in great and blue tit. Specifically, as density of great tit increased and temperature in winter increased both species started to reproduce later. Density of blue tit affected the relationship between spring temperature and blue and great tit laying date. Thus, both species start to reproduce earlier with increasing spring temperature as density of blue tit increases, which was not an expected outcome, since we expected that increasing spring temperature should advance laying date, while increasing density should delay it cancelling each other out. Climate warming and its interaction with density affects clutch size of great tits but not of blue tits. As predicted, great tit clutch size is reduced more with density of blue tits as temperature in winter increases. The relationship between spring temperature and density on clutch size of great tits depends on whether the increase is in density of great tit or blue tit. Therefore, an increase in temperature negatively affected the coexistence of blue and great tits differently in both species. Thus, blue tit clutch size was unaffected by the interaction effect of density with temperature, while great tit clutch size was affected in multiple ways by these interactions terms.Institute of Biology of Karelian Research Centre 0218-2019-0080Academy of Finland 265859Ministerio de Economía y Competitividad CGL-2016-79568-C3-3-

Effects of Interspecific Coexistence on Laying Date and Clutch Size in Two Closely Related Species of Hole-nesting Birds

Coexistence between great tits Parus major and blue tits Cyanistes caeruleus, but also other hole-nesting taxa, constitutes a classic example of species co-occurrence resulting in potential interference and exploitation competition for food and for breeding and roosting sites. However, the spatial and temporal variations in coexistence and its consequences for competition remain poorly understood. We used an extensive database on reproduction in nest boxes by great and blue tits based on 87 study plots across Europe and Northern Africa during 1957–2012 for a total of 19,075 great tit and 16,729 blue tit clutches to assess correlative evidence for a relationship between laying date and clutch size, respectively, and density consistent with effects of intraspecific and interspecific competition. In an initial set of analyses, we statistically controlled for a suite of site-specific variables. We found evidence for an effect of intraspecific competition on blue tit laying date (later laying at higher density) and clutch size (smaller clutch size at higher density), but no evidence of significant effects of intraspecific competition in great tits, nor effects of interspecific competition for either species. To further control for site-specific variation caused by a range of potentially confounding variables, we compared means and variances in laying date and clutch size of great and blue tits among three categories of difference in density between the two species. We exploited the fact that means and variances are generally positively correlated. If interspecific competition occurs, we predicted a reduction in mean and an increase in variance in clutch size in great tit and blue tit when density of heterospecifics is higher than the density of conspecifics, and for intraspecific competition, this reduction would occur when density of conspecifics is higher than the density of heterospecifics. Such comparisons of temporal patterns of means and variances revealed evidence, for both species, consistent with intraspecific competition and to a smaller extent with interspecific competition. These findings suggest that competition associated with reproductive behaviour between blue and great tits is widespread, but also varies across large spatial and temporal scales. © 2018 The Authors.

Repeated genomic signatures of adaptation to urbanisation in a songbird across Europe

Urbanisation is currently increasing worldwide, and there is now ample evidence of phenotypic changes in wild organisms in response to this novel environment, but the extent to which this adaptation is due to genetic changes is poorly understood. Current evidence for evolution is based on localised studies, and thus lacking replicability. Here, we genotyped great tits (Parus major) from nine cities across Europe, each paired with a rural site, and provide evidence of repeated polygenic responses to urban habitats. In addition, we show that selective sweeps occurred in response to urbanisation within the same genes across multiple cities. These genetic responses were mostly associated with genes related to neural function and development, demonstrating that genetic adaptation to urbanisation occurred around the same pathways in wildlife populations across a large geographical scale.Competing Interest StatementThe authors have declared no competing interest

A Survey of Music Therapists Working in Pediatric Medical Settings in the United States

Music therapy is becoming a standard supportive care service in many pediatric hospitals across the United States. However, more detailed information is needed to advance our understanding about current clinical practice and increase availability of pediatric music therapy services. The purpose of this cross-sectional survey study was to collect and summarize data about music therapists working in pediatric medical settings. Specifically, we collected information about (1) therapist demographics, (2) organizational structure, (3) service delivery and clinical practice, and (4) administrative/supervisory responsibilities. Board-certified music therapists working in pediatric medical settings (n = 118) completed a 37-item online questionnaire. We analyzed survey data using descriptive statistics and content analysis. Findings indicated that there is a ratio of approximately one music therapist for every 100 patient beds, that one-third of respondents are the only music therapist in their setting, and that half of the surveyed positions are philanthropically funded. Prioritizing patient referrals based on acuity was common (95.7%, n = 110), with palliative care and pain as the most highly prioritized needs. More than half of respondents reported serving in high acuity areas such as the pediatric intensive care, hematology/oncology, or neonatal intensive care units. We recommend replication of this survey in five years to examine growth and change in service delivery among pediatric music therapists over time, with additional studies to (a) explore how therapist-to-patient ratios influence quality of care, (b) identify factors that contribute to sustainability of programs, and (c) determine how expansion of services support a broader population of patients and families

Reliability of Various Size Oxide Aperture VCSELs,"

Abstract This paper presents Honeywell's most recent work on 850-nm oxide aperture vertical cavity surface emitting laser (VCSEL) reliability. The VCSELs studied have a range of aperture diameters from about 5 to 20 µm and the reliability effect of aperture diameter is of principal interest in this paper. Larger apertures generally exhibit greater reliability. Electrostatic discharge (ESD) sensitivity thresholds of the various oxide aperture VCSELs is discussed, again showing dependence on diameter, with larger being better. Results for humidity exposure are presented. Here we find no aperture size dependence, because none of the tested designs show significant susceptibility to humidity-induced degradation. It is demonstrated that, in addition to end-of-life degradation, VCSELs generally exhibit variation of performance characteristics during the early part of operating life. This often leads to a requirement for device burn-in. Honeywell's work in the area of wafer stabilization (trademarked under the name STABILAZE, patent pending) is introduced, showing how critical device parameters such as threshold and slope efficiency can be made to be unvarying over the product's life without the need for costly component or module-level burnins
