Soil bacterial population acts as a reliable indicator of ecosystem health in these human-perturbed areas. The goals of the present study were to isolate and characterize soil bacteria from an abandoned coal mine land that included an AMD site in southeast Kansas and to isolate acid-tolerant bacterial species for bioremediation purpose. Soil samples were collected seasonally from five topographically diverse locations at the mine land. Soil texture was evaluated and soil chemistry was analyzed using inductively-coupled plasma optical emission spectroscopy. Up to sixty morphologically different colonies were isolated by dilution plating of soil samples on nutrient rich media, characterized using physiological and biochemical tests, checked for their growth on selective acid media, and identified at species-level using 16S rRNA gene sequencing. Data showed that soil pH ranged from 2.4-6.8 and contained varied concentrations of arsenic, manganese, and iron. Total bacterial concentration was 102-106 CFU/g of soil. Biochemical tests revealed a diverse metabolic potential of the bacterial population. A total of 13 acid-tolerant bacterial strains were recovered. Majority of bacterial species belonged to phylum Firmicutes, followed by Actinobacteria, and Proteobacteria. Baseline measurements of culturable bacterial diversity as well as soil chemistry at AMD sites in this region are novel and the findings would have potential use in bioremediation of AMD sites.","PeriodicalId":76755,"journal":{"name":"Transactions of the Kansas Academy of Science.

Most previous studies have investigated shading by other plants, where spectral quality of light is changed. In this study, by contrast, several aspects of growth and reproduction were measured in Ageratina altissima and Rudbeckia laciniata (both grassland forbs in Asteraceae) grown for six weeks in a greenhouse where light was reduced to 10%, 50%, and 100% of ambient levels without changing spectral quality. Ageratina altissima was more responsive to light than was R. laciniata. In response to low light quantity, A. altissima displayed traits that were related to shade avoidance, common in grassland species, such as decreased chlorophyll content and biomass, fewer branches, leaves, and ramets, and decreased reproductive output. However, A. altissima also displayed traits that were consistent with shade tolerance, common in forest species, such as reduced elongation of stems, higher chlorophyll a/b ratio, reduced root and shoot biomass, and fewer and thinner leaves. Rudbeckia laciniata was less responsive to light treatments, only showing effects in leaf thickness and the SPAD chlorophyll index. There was no effect of light on leaf area, petiole length, or several chlorophyll fluorescence parameters in either species. Responses to low light quantity might involve a combination of shade avoidance and shade tolerance strategies in responsive species, potentially helpful as lighting conditions vary.","PeriodicalId":76755,"journal":{"name":"Transactions of the Kansas Academy of Science.

Although the use of chemical signals seems probable for chelonians, few studies have focused on this form of communication in turtles, and only in a limited number of species. We tested the response of male Painted Turtles Chrysemys picta to chemical signals exuded by conspecifics by examining whether male Painted Turtles spent more time near female or male Painted Turtles or a control (empty) section of a pool, based solely on chemical signals exuded by the stimulus animals. We completed 27 trials and recorded the time male turtles spent in each section of the pool (male, female or control). Male Painted Turtles spent the most time in the section of the pool that housed the female Painted Turtle and spent the least amount of time in the control section. A one-way ANOVA and Tukey's test showed a statistically significant difference between the time test males spent in the female section and control section. The time male Painted Turtles spent in the female and male sections did not differ significantly and no significant difference was found in the amount of time the test male spent in the male section and the control section. The results are consistent with the hypothesis that male Painted Turtles respond to chemical signals exuded by female Painted Turtles, potentially, to find mates. With many turtle populations declining, it is important to study aspects of their reproduction, including communication.","PeriodicalId":76755,"journal":{"name":"Transactions of the Kansas Academy of Science.

These earlier papers focused on tardigrades in central Iowa, living in either freshwater algae or in deciduous trees, and reported a total of only five recognized species in four genera. This project expands the known tardigrade diversity of the state through collection of specimens from both deciduous and coniferous trees in northern Iowa. Tardigrades were extracted from 29 moss and lichen samples collected from deciduous and coniferous trees in Hardin County during December 2015. 485 adult specimens and 74 eggs were collected, representing seven species (Milnesium cf. barbadosense, Milnesium burgessi, Milnesium eurystomum, Milnesium swansoni, Ramazzottius sp., Macrobiotus hibiscus, and Paramacrobiotus tonollii). Of these, one is a new species record for the United States (Milnesium cf. barbadosense), and all are new records for the state of Iowa. This is also the first report of a member of the genus Ramazzottius in Iowa. Pseudoplates, tardigrade structures that were only described for the first time in 2016, were also observed in all Milnesium specimens.","PeriodicalId":76755,"journal":{"name":"Transactions of the Kansas Academy of Science.

Each ecotype adapts to abiotic and biotic factors within its environment. These adaptations may prove more or less desirable to herbivores in the area. For instance, plants adapted to areas with greater rainfall tend to grow larger than those adapted to drier conditions. Wetter conditions might result in greater herbivore pressure, but according to the Resource Availability Hypothesis, individual plants tend to invest little in herbivore defenses when resources are abundant. Consequently, we hypothesized A. gerardii ecotypes adapted to wetter conditions might be more susceptible to herbivory and that ecotypes adapted to drier conditions might have evolved greater herbivore defense mechanisms. We tested this with feeding preference trials involving grasshoppers and leaves from five ecotypes of A. gerardii that represented plants adapted to wet and dry conditions. Scans of leaves before and after herbivory trials indicated 43 to 78 percent of leaf area remained, with no difference among ecotypes regarding which were favored by herbivores. We also hypothesized that leaves with more tannins would be less preferable to herbivores. This was tested by measuring leaf tannin concentration from five ecotypes of A. gerardii from four common gardens across a precipitation gradient. Leaf tannin concentrations ranged from 0.8 to 2.4% of leaf dry mass and were different among both sites and ecotypes. Site differences caused the biggest difference in leaf tannins, indicating a strong environmental influence on leaf tannin concentration. There was no correlation between tannin concentration and herbivory preference among ecotypes, indicating other factors are related to herbivore defense in A. gerardii.","PeriodicalId":76755,"journal":{"name":"Transactions of the Kansas Academy of Science.
