The Sarracenia pitcher plants are among the world’s most beautiful and intriguing plants, and being carnivorous adds an extra dimension of fascination. They are endemic to North America – 10 species are found only in the southeastern United States and one species is widely distributed, from the northeastern US and across Canada. They are easy to cultivate if you understand their basic needs and are grown the world over. Every botanical garden should have them because they are so popular with the public. They go hand-in-hand with other unusual carnivorous plants to make a display that is captivating (puns intended!) to both children and adults. This paper covers types of pitcher plants, their habitats, brief descriptions of the species, a key to identification, cultivation and a short note on conservation.

We review the taxonomy and ecology of Chloropidae (Diptera) associated with pitcher plants (Sarraceniaceae) in North America.Tricimba wheeleriMlynarek sp.n. is described from the pitchers ofSarracenia alataAlph.Wood andS. leucophyllaRaf. in the southeastern United States (Alabama, Mississippi).Aphanotrigonum darlingtoniae(Jones) associated withDarlingtonia californicaTorr. in northern California is redescribed, including the first description of male genitalic characters. A lectotype is designated forA. darlingtoniae. Published records of other species ofTricimbaLioy in pitcher plants in North America are considered accidental or facultative occurrences; published records ofAphanotrigonumDuda as pitcher plant associates in eastern North America are probably errors in identification.

Western flower thrips, Frankliniella occidentalis (Pergande), originally distributed throughout western North America (Bryan and Smith 1956), have since spread to greenhouses in the eastern United States and Canada, and to many other parts of the world (Brodsgaard 1989). Populations have established outdoors in the southeastern United States (Chamberlin et al. 1992) and in several other warm regions of the world (Brodsgaard 1993). but have failed to establish in Ontario (Broadbent and Hunt 1991) and the northern parts of Europe (Brodsgaard 1993). We have not found reports of western flower thrips overwintering outdoors in the northeastern United States.

Abstract The southeastern United States has been experiencing unexplained sugarberry (Celtis laevigata) mortality for over a decade, representing one of the most severe and widespread Celtis mortality episodes ever reported from North America. Here we describe external symptoms, progression of mortality, and the known geographic extent of the problem. More than half of all trees monitored at one site within the affected area died over five years of observation. Although many trees died within a year of first exhibiting symptoms (e.g., small yellow leaves, branch dieback, premature leaf fall), many others continued living for years after becoming symptomatic. A preliminary insecticide trial found no improvements in survivorship among trees treated with insecticides, emamectin benzoate and imidacloprid, relative to control trees. Our findings suggest the problem will likely continue and become more widespread in the coming years. Study Implications Sugarberry mortality in urban and forested environments is an ongoing problem that has the potential to spread throughout the southeastern United States and perhaps more widely, depending on the susceptibility of other native Celtis species. Many trees die within a year of first showing external symptoms, whereas others can live for many years after appearing symptomatic. Declining trees in rights-of-way and public spaces are presenting costly hazards to cities, and canopy gaps in natural areas are likely to facilitate the establishment and spread of invasive plants. Studies aimed at determining the cause of this problem are urgently needed.

Considerable Intensity

A current question being debated with considerable intensity is whether or not certain geographic areas act as centers of evolutionary radiation and supply species to other areas that are less active or less effective in an evolutionary sense. Darwin (1859) was the first to write about centers of origin which he called “single centers of creation.” He argued that each species was first produced within a single region and that it subsequently migrated from that area as far as its powers of migration and subsistence under past and present conditions permitted. Adams (1902), in discussing the influence of the southeastern United States as a center of distribution for the flora and fauna of North America, provided a series of criteria for the determination of “centers of dispersal.” His first, and evidently most important criterion was the location of “the greatest differentiation of a type.”

Fire Weather Index

AbstractThe Haines index (HI) is a fire-weather index that is widely used as an indicator of the potential for dry, low-static-stability air in the lower atmosphere to contribute to erratic fire behavior or large fire growth. This study examines the interannual variability of HI over North America and its relationship to indicators of large-scale circulation anomalies. The results show that the first three HI empirical orthogonal function modes are related respectively to El Niño–Southern Oscillation (ENSO), the Arctic Oscillation (AO), and the interdecadal sea surface temperature variation over the tropical Pacific Ocean. During the negative ENSO phase, an anomalous ridge (trough) is evident over the western (eastern) United States, with warm/dry weather and more days with high HI values in the western and southeastern United States. During the negative phase of the AO, an anomalous trough is found over the western United States, with wet/cool weather and fewer days with high HI, while an anomalous ridge occurs over the southern United States–northern Mexico, with an increase in the number of days with high HI. After the early 1990s, the subtropical high over the eastern Pacific Ocean and the Bermuda high were strengthened by a wave train that was excited over the tropical western Pacific Ocean and resulted in warm/dry conditions over the southwestern United States and western Mexico and wet weather in the southeastern United States. The above conditions are reversed during the positive phase of ENSO and AO and before the early 1990s.

The article is based on an analysis of certain aspects of how the public opinion of selected nations in years 2001–2016 perceived the American foreign policy and the images of two Presidents of the United States (George W. Bush, Barack Obama). In order to achieve these research goals some polling indicators were constructed. They are linked with empirical assessments related to the foreign policy of the U.S. and the political activity of two Presidents of the United States of America which are constructed by nations in three segments of the world system. Results of the analysis confirmed the research hypotheses. The position of a given nation in the structure of the world system influenced the dynamics of perception and the directions of empirical assessments (positive/negative) of that nation’s public opinion about the USA.

The importance of the manuscript pontificals for the study of the medieval evolution of the Latin liturgy needs no reaffirmation here. The state of the published descriptions and classifications of these manuscripts, however, is not commensurate in all cases with what their importance would lead one to expect.Ehrensberger has provided a full description of the manuscript pontificasl preserved in the Vatican Library; although this is no longer recent, it is invaluable in the absence of a complete catalogue of the Vatican manuscripts. The monumental work of Leroquais describes in detail the manuscript pontificals extant in the public libraries in France; as most of the pontificals in France appear to be in public libraries, this work is fairly comprehensive in its coverage. Dom Anselm Strittmatter has listed and classified the liturgical manuscripts preserved in the United States. For pontificals in other countries, however, there exist no such reference works. Professor Richard Kay of the University of Kansas is currently compiling a handlist in which all the manuscript pontificals extant throughout the world will be cited and briefly identified, but not fully described. Until this appears, anyone working on pontificals or on ordines normally included in pontificals will quite likely have to work systematically through innumerable catalogues of manuscript collections to cover every library, city by city, for a frequently minimal return.

Despite relatively equal proportions of boys and girls enrolled in STEM courses during grade school, women are significantly underrepresented in STEM degrees and occupations around the world (Hill, Corbett, and St. Rose, 2010). The field of mathematics reflects this trend. Our focus in this article is on three women graduate students in mathematics at a University in the Southeastern United States. In particular, we were interested in their identities that include their perspective on the graduate program. Specifically, we sought to understand the norms, expectations, and resources of the social situation in which their identities were developing. As will become apparent, the three students illustrate different identities as they participated in graduate school mathematics.
