Ectoparasitic Arthropods Collected From Some Northern Ohio Mammals

Ectoparasitic arthropods were collected from some fur-bearing mammals in northern Ohio. Specimens representing seven mammalian species were examined and found to collectively harbor acarines, fleas, and biting lice. Species determinations were made and new host and state records noted

Drosophilidae (Diptera) Collected in Spring in Michigan

Drosophilids in mid-Michigan overwinter in a preadult stage. One hun- dred twenty-two individuals (84 f, 38 m) representing 14 species were collected over bait in April and May 1992. All appeared recently emerged and had entire wings. This agrees with earlier reports in Michigan and Massachusetts that Drosophila affinis group species overwinter as preadults. Among the species overwintering as preadults in Michigan, Drosophila affinis, D. algonquin, D. athabasca, D. robusta, D. falleni and D. recens have been found to overwinter as adults in New York Latitude and climate may play a role in drosophilid overwintering stage

Pathotypic diversity of Hyaloperonospora brassicae collected from Brassica oleracea

Downy mildew caused by Hyaloperonospora brassicae is an economically destructive disease of brassica crops in many growing regions throughout the world. Specialised pathogenicity of downy mildews from different Brassica species and closely related ornamental or wild relatives has been described from host range studies. Pathotypic variation amongst Hyaloperonospora brassicae isolates from Brassica oleracea has also been described; however, a standard set of B. oleracea lines that could enable reproducible classification of H. brassicae pathotypes was poorly developed. For this purpose, we examined the use of eight genetically refined host lines derived from our previous collaborative work on downy mildew resistance as a differential set to characterise pathotypes in the European population of H. brassicae. Interaction phenotypes for each combination of isolate and host line were assessed following drop inoculation of cotyledons and a spectrum of seven phenotypes was observed based on the level of sporulation on cotyledons and visible host responses. Two host lines were resistant or moderately resistant to the entire collection of isolates, and another was universally susceptible. Five lines showed differential responses to the H. brassicae isolates. A minimum of six pathotypes and five major effect resistance genes are proposed to explain all of the observed interaction phenotypes. The B. oleracea lines from this study can be useful for monitoring pathotype frequencies in H. brassicae populations in the same or other vegetable growing regions, and to assess the potential durability of disease control from different combinations of the predicted downy mildew resistance genes

Hepaticae of Cerro Venamo, Venezuela, collected by J. Steyermark

A revision of herbarium material (NY) from Cerro Venamo, Venezuela (5°59’ N, 61°23’ W, 1890 m) yielded 77 hepatic species in 44 genera and 13 families. Most species have a neotropical distribution (75,32%), 6,49%, are pantropical and 9,09% are reported only from the tepuis

Human Gait Database for Normal Walk Collected by Smart Phone Accelerometer

The goal of this study is to introduce a comprehensive gait database of 93 human subjects who walked between two endpoints during two different sessions and record their gait data using two smartphones, one was attached to the right thigh and another one on the left side of the waist. This data is collected with the intention to be utilized by a deep learning-based method which requires enough time points. The metadata including age, gender, smoking, daily exercise time, height, and weight of an individual is recorded. this data set is publicly available

Replicability of data collected for empirical estimation of relative pollen productivity

The effects of repeated survey and fieldwork timing on data derived from a recently proposed standard field methodology for empirical estimation of relative pollen productivity (RPP) have been tested. Seasonal variations in vegetation and associated pollen assemblages were studied in three contrasting cultural habitat types; semi-natural ancient woodlands, lowland heaths, and unimproved, traditionally managed hay meadows. Results show that in woodlands and heathlands the standard method generates vegetation data with a reasonable degree of similarity throughout the field season, though in some instances additional recording of woodland canopy cover should be undertaken, and differences were greater for woodland understorey taxa than for arboreal taxa. Large differences in vegetation cover were observed over the field season in the grassland community, and matching the phenological timing of surveys within and between studies is clearly important if RPP estimates from these sites are to be comparable. Pollen assemblages from closely co-located moss polsters collected on different visits are shown to be variable in all communities, to a greater degree than can be explained by the sampling error associated with pollen counting, and further study of moss polsters as pollen traps is recommended

The Distribution of Revenues From State-Collected Consumer Taxes

Värdegrundsarbetet i förskolan där genus och likabehandling står i fokus är ett ämne som skall arbetas aktivt med och det var detta som var grunden i underökning. Undersökningen utgick ifrån två frågor som handlade om pedagogernas kompetens i genusvetenskap samt vilka genuspedagogiska strategier som de använde i arbetet med barnen. För att undersöka detta så valde jag att använda mig av en halvstrukturerad enkät där de flesta frågorna var av öppen karaktär för att kunna fånga vad pedagogernas kunskap om de olika genusvetenskapliga begreppen. De slutna frågorna fångade vilka genuspedagogiska strategier som pedagogerna använde i sitt arbete med barnen. 40 enkäter delades ut till pedagogerna i ett rektorsområde. Från resultatdelen kunde det utläsas att det var många olika definitioner på de genusvetenskapliga begreppen och att flertalet av pedagogerna inte hade samma syn som forskningen kring om det beror på det sociala eller det biologiska när barnen positionerar sig som pojkar eller flickor. Resultatet visade också att endast ett fåtal pedagogerna använder sig av det komplicerande och normkritiska arbetssättet med barnen och att lite fler än hälften tycker att de har tillräckligt med kunskap för att arbeta med genus. Slutsatser som kunde dras från resultaten från enkäten är att pedagogernas kompetenser i de genusvetenskapliga begreppen är på olika nivå och att de varierar väldigt mycket. Därför drog jag den slutsatsen att det är därför som det komplicerande och normkritiska arbetet inte används i arbetet med genus i förskolan. Ändå så ansåg flertalet av de pedagoger som inte arbetade med det komplicerande och normkritiska arbetet att de ändå hade tillräckligt med kunskap i genus. Kompetens i ett ämne gör att det är möjligt att ta ut svängarna, att verkligen se hur barnen gör genus i barngruppen och att ifrågasätta normer i samhället tillsammans med barnen
