Integrative Assessment

Sediments were dated and the quality assessed by polyphasic approach in an area of Lake Saimaa, which has received waste water from bleached kraft pulp production since 1954. The chosen nonrecipient forest Lake Pyylampi was situated in the same area. The activities of the enzymes butyrate-esterase and aminopeptidase were depressed at the depth of 2 to 8 cm in the recipient but not in the forst lake sediment. In the same layers the contents of EOX-C1 and toxicity to Vibrio fischeri were very high compared to those above or below. Toxicity to microbial community in the 2 to 8 cm layer was also indicated by a gap in the ATP content and a drop in diatom species richness from the 70 species to < 50 reflecting decreased water quality of the pelagic area. All these changes dated to the period of heavy organic halogen discharges, from 1960 to late 1980s, which led to sediment accumulation of solvent soluble halogen at a depth of 2 to 8 cm, to 6.4 g m−2 (cm)−1. In the most polluted sediment layers heavy metal accumulation was too little to be related to the toxicity of these layers. Almost complete recovery of both the sediment microbial ecosystems and of the pelagic diatoms occurred after elemental chlorine was completely substituted by chlorine dioxide and biological treatment adopted for wastewaters. Butyrate-esterase and aminopeptidase, but not phosphatase, activities correlated positively with the ATP content of the sediment. Butyrate-esterase may be used as a tool to estimate microbial biomass.

Integrative Assessment

This chapter aligns the tenets of critical pedagogy with current practices of assessment in the United States. The author posits that critical pedagogy is an appropriate lens through which to view assessment, and argues against the hegemonic practices that support marginalization of students. Grounded in critical theory and based on Marxist ideals, the content supports the notion of teaching and learning as a partnership where the desire to empower and transform the learner, and open possibilities for the learner to view the world and themselves in that world, are primary goals. Political mandates to evaluate teacher performance and student learning are presented and discussed. In addition to the formative and summative assessments that teachers routinely do to students, the author suggests integrative assessment, where students with the teacher reflect together on the learning experience and its outcomes. The chapter includes specific examples from the author’s own teaching that operationalize the ideas presented.

Integrative Assessment

This study aimed to assess the diversity of species in the Espinhaço Range (ER), eastern Brazil, using as a model the diverse plant family Gentianaceae and focusing on the Parque Municipal de Mucugê—Projeto Sempre Viva (PMM), a conservation unit with predominance of  “campo rupestre”. For this purpose, fieldwork expeditions were carried out between the years 2016–2018 along with a survey of species of this family recorded for this conservation unit in public databases. For comparative purposes, the listing of species from other five areas of the ER were also surveyed and we modeled the distribution of species endemic to these mountains, taking into account that they have their restrict distribution, high habitat specificity and importance to the ecosystem. The results indicated the presence of 33 species of Gentianaceae for the ER, eight of them occurring in the PMM. Comparatively, the results pointed to a greater floristic similarity between the PMM, Pico das Almas and Catolés, due to the presence of seven common species. Predictive distribution modeling supports high endemicity of the analyzed species, given their low environmental suitability outside the ER. The models also allowed us to identify possible areas showing high Wallacean shortfall for these species. Thus, the results reinforce the importance of field work, access to physical and digital botanical collections and the integrated use of tools for a more reliable survey of biodiversity.

Methodological Considerations

Synopsis One of the key foci of ecoimmunology is understanding the physiological interactions between reproduction and immune defense. To assess an immune challenge, investigators typically measure an immune response at a predetermined time point that was selected to represent a peak response. These time points often are based on the immunological responses of nonreproductive males. Problematically, these peaks have been applied to studies quantifying immune responses of females during reproduction, despite the fact that nonreproductive males and reproductive females display fundamentally different patterns of energy expenditure. Previous work within pharmacological research has reported that the response to the commonly-used antigen keyhole limpet hemocyanin (KLH) varies among individuals and between females and males. In this heuristic analysis, we characterize antibody responses to KLH in females with varying reproductive demands (nonreproductive, lactating, concurrently lactating, and pregnant). Serum was taken from one animal per day per group and assessed for general and specific Immunoglobulins (Igs) G and M. We then used regression analysis to characterize the antibody response curves across groups. Our results demonstrate that the antibody response curve is asynchronous among females with varying maternal demands and temporally differs from the anticipated peak responses reflected in standardized protocols. These findings highlight the importance of multiple sampling points across treatment groups for a more integrative assessment of how reproductive demand alters antibody responses in females beyond a single measurement.
