Abstract:
Problem: Special stains such as the Giemsa, the Alcian blue (AB) and the Periodic Acid Schiff (PAS) are widely used for gastric and/or esophageal biopsies for the diagnosis of Helicobacter pylori (H. pylori) and intestinal metaplasia (IM). The purpose of our study was to determine if these stains are actually needful
 Methods: We retrospectively studied 209 gastric and esophageal biopsies. We evaluated the H. pylori status on hematoxylin and eosin (H&E) stained slides and the presence of IM and finally we examined the special stains.
 Results: 23% of cases were H. pylori-positive. H&E stain had a high degree of accuracy (92,1%). The Giemsa stain was positive in 23,7% and negative in 71,8%. The Giemsa was useful in 16,7% biopsies. The AB revealed goblet cells in 4,8% cases. AB sensibility was 90,9%. From the 208 slides stained with PAS, 4,3% were classed IM-positive. PAS sensibility was 90%. The two special stains (AB and PAS) have made no diagnostic gain. 
 Conclusions: Routine special stains for every single gastric and/or esophageal biopsy are not required and H&E assessment combined with selective ordering of these stains will identify all cases of H. pylori gastritis and IM.

Abstract:
The objective is to find a practical balance between quality and performance for daily high volume whole slide imaging. We evaluated whole slide images created by various scanners at different compression factors to determine the best suitable quality factor (QF) needed for pathological images of special stains.Method: We scanned two sets of eight special stains slides each at 0.50 μm/pixel resolution in Hamamatsu scanner at six and fiveQFlevels respectively to generate 72 images which were observed at a calibrated monitor by imaging specialists, a histo-technician, and a pathologist to find the most suitableQFlevel for special stains in digital slides.Results: Most special stains images were acceptable at QF 30 except for the stain Reticulin where the lowest acceptableQFwas 50. The compression of images fromQF90 toQF50 reduced the size of the images by 62.73%.Conclusion: 0.50 μm/pixel images atQF50 or above were found suitable 12 special stain.

Abstract:
Background: Gender determination becomes the first priority in process of identification of a person by a forensic investigator in case of mass disaster, crime investigations, and ethnic studies. Demonstration of nuclear sex plays a vital role in determining the gender of an individual. Barr bodies (BB) are known to arise from the inactivation of the X chromosome in a female somatic cell. They are basophilic structures with varying morphology measuring approximately 0.8 × 1.1 microns in the nucleus during interphase. Various nuclear stains such as Thionine, Papanicolaou, Feulgen, Cresyl-violet, Giemsa, Aceto-orcein, and acridine orange & Routine stains can validate Barr bodies. Aim To evaluate the efficacy of Feulgen, Giemsa, and H&E stains in the demonstration of Barr bodies. Materials And Method Buccal smears were prepared from 25 males & 25 females. These smears were stained by Feulgen, Giemsa & Routine staining methods. The Barr body identification was determined by the presence of a darkly stained condensed area on nucleoplasm. The frequency of Barr body was examined by observing 100 nuclei per smear under a binocular light microscope at 100 magnification. For all BB-positive cases, Barr Body Index(BBI) was calculated and compared for the different stains used. Result Buccal cytological smears stained with Feulgen, Giemsa, and Routine stains. Samples with a presence of Barr bodies ≤2 were recorded as male and those with >2 were recorded as female under microscopic findings. The percentage of Barr bodies in Feulgen-stained slides ranged from 30.2 - 37.9 among females and 0 - 0.1 in males, Giemsa slides ranged 14.2 - 22.2 from among females and 0 - 0.3 in males, while with Routine stained slides ranges recorded were10.2 - 14.9 in females and 0 - 0.5 in males. The sensitivity of Feulgen, Giemsa, and Routine stain for detecting sex accurately was 100% and specificity was 100%, 98%, and 94% respectively. Conclusion Feulgen stain proved to be better than Giemsa and routine stain for visualizing Barr Bodies.

Abstract This article provides an overview of the pathology of alveolar soft part sarcoma, focused on its morphology, special stains useful in diagnosis, and the clinical and radiographic features of the disease. Alveolar soft part sarcoma is a rare neoplasm of unknown histogenesis with poor prognosis. Although there are several immunohistochemical stains available to help reach the diagnosis, the morphology of the tumor should be considered the main diagnostic feature. The periodic acid–Schiff stain is the best single stain that supports the diagnosis.

Abstract:
Background: Nocardia, a gram-positive aerobic bacillus of the Actinomycetales family, is a significant opportunistic pathogen in immunocompromised individuals. Clinical and radiological features of pulmonary nocardiosis are nonspecific and can be misdiagnosed as tuberculosis, pneumocystis, staphylococcal or fungal infections, or as malignancy. Aspiration cytology with special stains is a quick and effective approach for accurate diagnosis. Materials and Methods: We present 7 cases of pulmonary nocardiosis, admitted to the pathology department in a tertiary-care hospital in Punjab. Clinical findings, immune status, laboratory tests, chest radiographs, and computed tomography scans were reviewed. Cytologically, special stains like 1% Ziehl-Neelsen (ZN), 20% ZN, periodic acid-Schiff (PAS), Grocott methenamine silver (GMS), and reticulin stains were studied along with May-Grünwald Giemsa, Papanicolaou, and hematoxylin and eosin. Results: All the patients were immunocompromised. The radiological changes were nonspecific. Cytomorphology showed acute and chronic inflammatory infiltrates with necrosis. None of the cases showed well-defined granulomas. GMS, modified 1% ZN and, Gordon and Sweet reticulin stains highlighted the delicate filamentous bacteria in all cases. PAS and 20% ZN stain for tuberculous bacilli were uniformly negative. Conclusion: FNAC can provide a quick and accurate diagnosis of nocardiosis and thereby facilitate timely medical management.

Abstract:
Granulation reaction pattern is defined as “Granulomatous inflammation is a form of chronic inflammation characterized by collections of activated macrophages, often with T lymphocytes, and sometimes associated with central necrosis”. Granulomatous disease comprises some of the widespread diseases in the world such as leprosy and tuberculosis. Granulomatous inflammation in the skin could be due to infectious or non-infectious causes. Common infectious causes of granulomatous skin lesions include leprosy, TB, leishmaniasis and fungal infections. Uses of special stains such as ZN stain for TB, Fites stain for leprosy, Giemsa stain for leishmaniasis; Grocott methenamine silver stain and PAS stain for fungal infections may be helpful.

Abstract:
In routine diagnostic activity, pathologists may be confronted with nervous system tumors. The lack of clinical information, economic restrictions for additional testing, and the lack of expertise in neuropathology may render the diagnosis challenging. The goals of this study were to assess the agreement in diagnosing nervous system tumors in domestic carnivores among 4 board-certified surgical pathologists without particular expertise in neuropathology and a neuropathologist expert, and to investigate the utility of special stains frequently used in routine diagnostic laboratories. Forty-six tumors (7 cats, 38 dogs, and 1 unknown carnivore) were retrieved and 1 hematoxylin and eosin–stained slide per tumor was selected. Diagnoses (tumor type and subtype) were formulated based on histological features and available clinical information. Confidence in the diagnosis was also scored. Subsequently, a panel of histochemical and immunohistochemical stains (Gordon Sweet silver stain and immunohistochemistry for AE1/AE3, vimentin, glial fibrillary acid protein, S100, neuron-specific enolase and neurofilament) was evaluated by the pathologists, who either confirmed or changed their original diagnoses. Intraobserver and interobserver agreement and confidence in relation to diagnosis before and after analysis of special stains were assessed. The use of special stains increased the complete agreement among surgical pathologists, with regard to tumor type, from 63% to 74%. Cases with a high confidence score had a higher interobserver agreement than cases with a low confidence score. These results suggest that pathologists without expertise in neuropathology agree in the diagnosis of most nervous system tumors, and special stains available in most laboratories only slightly increase this agreement.

Abstract:
Grocott metoden är den känsligaste metoden för infärgning av svampstrukturer i histologisk vävnad i jämförelse med till exempel Periodic Acid-Schiff (PAS). Handhavandet av det cancerogena oxidationsmedlet kromsyra samt tidsaspekten för Grocott är signifikanta problem. Syftet med studien var att undersöka om den automatiserade färgningsmetoden för Grocott ger likvärdiga resultat som vid den manuella färgningsmetoden. Tolv preparat färgades med både den manuella och den automatiserade metoden för Grocott. Den automatiserade färgningsmetoden använder ett färdigt kit med alla ingående lösningar. Visuell bedömning av preparaten utfördes med hjälp av legitimerade biomedicinska analytiker samt en patolog. Svampstrukturer i åtta av ela preparat samt kontroll bedömdes vara tydligare infärgade med den automatiserade metoden i färhållande till den manuella. Svampstrukturer i endast ett preparat bedömdes vara tydligare infärgade med den manuella metoden. Resterande två preparat visade inga svampstrukturer. Resultaten tyder på att den automatiserade färgningsmetoden för Grocott ger likvärdiga, alternativt tydligare infrägning av svampstrukturer i jämförelse med den manuella metoden.<br>The Grocott method is the most sensitive staining method for fungal structures in histological tissues in comparison to for example Periodic Acid-Schiff (PAS). Usage of the cancerogenic chromic acid and the time aspect for Grocott are significant problems. The aim of this study was to examine if the automated staining method for Grocott provides equivalent results in comparison to the manual staining method. Twelve tissue sections were stained with both the automated and the manual method. The automated method contains a kit with all solutions. Visual evaluation was conducted with authorized biomedical scientists and a pathologist. Fungi structures in eight of eleven tissue sections and a control were evaluated as more distinct in the automated method in comparison to the manual method. Fungal structures in one of the tissue sections were evaluated more distinct in the manual method. In the remaining two tissue sections, no fungal structures were identified. Results from this study indicates that the automated staining method for Grocott provides equally, alternatively more distinct fungal staining in comparison to the manual method.

Abstract:
Heart failure (HF) is a leading killer in the Western world and is a serious financial burden on health care budgets. Moreover, the life quality of many HF patients decreases through multiple morbidities. In order to improve the prognosis of HF patients, evidence-based treatments are developing. This thesis investigated areas of secondary prevention in HF without evidence. Subjects included those accessing cardiac rehabilitation (CR) referral, exercise-based CR and aspirin and statin prescription. Outcomes consisted of all-cause mortality, hospital admission and exercise capacities. HF was evaluated mainly as the reduced ejection fraction (HF-REF) subtype, while applied statistical models were parametric and non-parametric. Missing values were assessed through multiple imputations. First, the CR referral effect on mortality after an acute myocardial infarction event was evaluated. The Evaluation of Methods and Management of Acute Coronary Events (EMMACE)-I and II observational studies demonstrated CR referral as an independent predictor of survival in 2003, but not in 1995. Similar results were shown in HF subgroups. Although decreasing between the studies, CR referral was associated with treatment inequalities, thus suggesting a risk-treatment paradox. Second, the effect of enrolment in exercise-based CR in HF patients was assessed through a meta-analysis incorporating randomised controlled trials (RCTs). Over a minimum of six months, follow-up exercise capacities and hospital admissions significantly improved in the exercise intervention group as compared with the control group. In contrast, mortality was not significantly improved through exercise, although a trend suggested exercise to be superior to a sedentary lifestyle. Confounders were patient selection in RCT recruitment and the unequal quality of care. Third, the average treatment effects of aspirin and statins in HF patients (EMMACE studies) improved survival rates during 90 months follow-up. In HF populations, CR attendance influenced key outcomes significantly, whereas aspirin and statins were beneficial to survival in observational studies.

Abstract:
Statins and fibrates are the most widely used pharmaceuticals in developed countries for the treatment of hyperlipidemia. They reach the aquatic environment mainly via wastewater treatment plants and have been detected at concentrations of ng to µg/L. They are “pseudopersistent” due to their continuous and increasing input into the aquatic environment. Cholesterol is essential to all animals, so inhibition of its synthesis by these drugs could have negative consequences in non-target species. Currently little is known regarding the possible effects of statins and fibrates on aquatic organisms. Thus, this thesis investigates the effects of atorvastatin (ATV; statin) and gemfibrozil (GEM; fibrate) on rainbow trout and zebrafish in vivo and in vitro. Intraperitoneal injection of ATV, GEM, or the combination of the two drugs (A+G) into rainbow trout resulted in a nearly 30% reduction of cellular cholesterol content. Additionally, gene expression related to lipid homeostasis (LDL-r, HMGCR-1, and SREBP-1) was elevated. Furthermore, plasma creatine kinase activity and skeletal muscle gene expression related to rhabdomyolysis (atrogin-1 and f-box 25) were elevated. Plasma cortisol concentration was reduced in injected trout, suggesting that either the reduction in cholesterol resulted in treated fish lacking a proper stress response or that the treated fish were simply not responsive to the stress protocol. Feeding zebrafish ATV, GEM, or A+G daily over a 30 day period resulted in nearly a 30% reduction of whole-body cholesterol content and a concomitant change in gene expression related to lipid homeostasis (SREBP-1, SREBP-2, HMGCR-1, PPARα, and PPARγ). Moreover, sex steroids (testosterone and estradiol) were also reduced. Finally, exposing rainbow trout hepatocytes to ATV at 4.5 or 45 µg/L for 3 or 6 h resulted in reduced 14C incorporation into cholesterol and cholesteryl ester. Elevated gene expression related to lipid homeostasis (HMGCR-1, SREBP-1, and PPARγ) also occurred. This thesis demonstrated that ATV and GEM affected fish cholesterol and steroid hormone contents, as well as molecular markers of rhabdomyolysis. Whether these changes impact fish fitness remains to be determined.

Abstract:
The rewards and sanctions associated with high-stakes testing may induce educators to participate in practices that will ensure the elimination of the scores of low-achieving students from the testing pool. Two ways in which scores may be eliminated is through retention or referral to special education. This study examined the use of these practices at 179 elementary schools in Miami-Dade County Public Schools, the 4th largest school district in the country. Between- and within-subjects designs were analyzed using repeated measures analysis of variance to compare retention and referral to special education practices over a five-year period of time, two years prior to and two years after the implementation of Florida's high-stakes test, the Florida Comprehensive Assessment Test, FCAT. Significant main effects for referral and retention over time were demonstrated. The use of retention steadily increased over the first three years, with its usage maintained during the fourth year. While the use of referral actually decreased from the first to second years, a significant change occurred after the implementation of the FCAT. Examination of the use of these practices according to student and school characteristics revealed significant differences. Increases in the use of referral across time was significant for Black, non-Hispanic and Hispanic students, all limited English proficiency population categories, medium and low socioeconomic status category schools, all grade levels, and for schools with accountability grades of A, C, D and F with the most striking absolute increase occurring for F schools. Increases in the use of retention across time were significant for all ethnic groups, limited English proficiency categories, and socioeconomic status categories, for grades kindergarten through four and by gender. Significant increases occurred for schools with accountability performance grades of C, D and F; however the most dramatic increase occurred for the F schools. A direct relationship between performance category grade of school and their use of retention was demonstrated. The results suggest that schools changed their use of referral and retention in response to the implementation of the FCAT.

Abstract:
Thesis advisor: David Scanlon<br>Students' with moderate special needs learning difficulties often manifest as reading struggles. These students commonly struggle with decoding words because of weak phonics skills, limited automatic recognition of high frequency words and/or limited vocabulary. A further challenge for the struggling readers is to focus on comprehension while decoding. Given that these students reading comprehension and fluency generally do not improve commensurate with reading demands as they move through school, exploring other possibilities such as the use of theatre arts techniques to teach English/Language Arts may identify an alternative intervention that builds comprehension and fluency in academic reading. Through my experience as a teacher I have used theatre in the classroom as a teaching and motivational tool. This study was conducted using a multiple case study design accompanied by the teacher researcher's perspective on the impact of the theatre infused curriculum. This dissertation focuses on the effect of a reading comprehension and fluency curriculum infused with theatre techniques on students' with moderate special needs literacy engagement, fluency, and comprehension. Informing this study is empirical research on teaching reading comprehension and fluency to students with moderate disabilities, as well as empirical research on the use of theatre techniques in curriculum. Data included reading performances and outcomes, observations of students, a teacher reflection journal, and student interviews. Thematic analysis was used to develop codes to inform the study's major themes. The study has four main findings: study participants who put in the most effort increased their comprehension score, all study participants, regardless of their reading levels or reading rates on the pre-test, made improvements on both by the end of the nine week study, writing assignments in the character analysis and skit writing activities require longer periods of exposure for the study participants to master them, and performing builds confidence over time, in a supportive environment<br>Thesis (PhD) — Boston College, 2014<br>Submitted to: Boston College.

Abstract:
This study examined Early Childhood Special Educators' perceptions of play as a developmentally appropriate practice in special education prekindergarten classrooms in one southeastern school district. Through purposeful sampling, eight prekindergarten special educators were identified because they held multiple teaching certifications and some held National Board certification. The participants had many years of experience in pre-kindergarten special education, and were professional development trainers, teacher mentors and or leaders in the prekindergarten special education community. These eight accomplished pre-kindergarten special education teachers were interviewed using an informal, semi-structured format about their beliefs concerning play, how they implement it in their classrooms as well as their perspectives on barriers to play. The participants identify the supports needed to implement play as a developmentally appropriate practice in special education prekindergarten classrooms. The findings reveal that Early Childhood Special Educators' believe in play as a developmentally appropriate practice and state that play is foundational to their practice in prekindergarten classrooms for children with special needs. Implications for future research and practice are included.

Abstract:
Research has provided ample evidence supporting the notion that interaction with books during early childhood enhances the development of reading skills (Bus, van IJzendorn, & Pellegrini, 1995; Dickinson & Smith, 1994; McKeown & Beck, 2004; Sénéchal & LeFevre, 2002). Additionally, we know there are substantial disparities in children’s experiences with language, vocabulary, and early literacy prior to entering kindergarten. These disparities have a lasting effect on later academic success (Catts, Hogan, & Fey, 2003; Hart & Risley, 1995: Snow, Burns, & Griffin, 1998). Children at greatest risk for poor language and literacy skills are young children who live in poverty and young children identified at-risk for developmental delays and disabilities.

Abstract:
Although all spiders possess fluorophores in their hemolymph, the expression of external fluorescence is much more restricted. The purpose of this study was to evaluate differences in externally-expressed fluorescence between sexes, life stages, and species of spiders. To approach this question, we developed novel instrumentation to capture fluorescence with photographs of our specimens. We paired these fluorescence measurements with spectrometer measurements to attempt to determine the role that fluorescence plays in the overall coloration in spiders. The study was divided into four sections. First, we examined how fluorescence varies in sexes and life stages in Misumena vatia, an ambush predator that typically preys on insects when they are on flowers. We found that adult females possess brighter external fluorescence than males in all body areas that we measured. We also found that external fluorescence remains relatively similar through life stages in females, but darkens over the course of a male's life. It is likely that the differences between males and females relate to differences in feeding ecology. External fluorescence may contribute to a visual signal allowing females to visually blend in with flowers. The second study involved a series of experiments to determine whether freezing spiders at a temperature of -80°C affects their fluorescence intensity. In spiders considered “white thomisids”, fluorescence intensity increased after freezing, whereas fluorescence brightness in darker-pigmented spiders did not change to any similar extent. It seems likely that tissue trauma due to freezing is the cause of increased fluorescence intensity after freezing. The third study examined fluorescence brightness across ages and life stages of Araneus diadematus, a spider which is exposed to the sun, but builds large webs in which to snare prey. We found that, unlike M. vatia, adult males are the more brightly fluorescent sex, with adult females and all immature life stages possessing significantly less bright external fluorescence. It is unclear why these differences exist, but differences in ecology between adult males and all other life stages could play a role. Additionally, dim fluorescence may contribute to subtle patterning and/or convey photoprotection benefits to immatures and adult females. In the final study, we examined external fluorescence across the Thomisidae family. Because of a relatively large number of species with a small sample size, we divided them into “white” and “dark” thomisids based on taxonomy and what is known about ecology. The white thomisids tend to be prey on insects on the exposed surfaces of flowers, whereas dark thomisids more often reside in leaf litter and crevices. We found that white thomisids fluoresce more brightly than dark thomisids. There were no differences between the sexes in either group, however. The differences between white and dark thomisids may be related to differences in feeding ecology, whereas males and females of the same group tend to have similar ecological characteristics, and also possess similar levels of fluorescence brightness.

Abstract:
The social significance of donkey milk for human health stems from its potential advantages for vulnerable populations, including children and those with special dietary needs. The variation in its composition throughout lactation indicates that it can be adapted to fulfil the specific nutritional demands of these groups. The focus of this paper is to investigate the chemical profile of donkey milk and the changes that occur during lactation. The study was performed on samples taken at various stages of lactation, from colostrum to milk. The results revealed fluctuations in protein, fat, lactose and dry matter, reflecting the milk's adaptation to the changing needs of the foals. The results indicate a significant increase in lactose content from 6.24% in the second month of lactation to 6.42% in the sixth month. Regarding the protein level, it decreased from 1.88% in early lactation to 1.41% during late lactation. This study has important implications for the use of donkey milk in human nutrition, providing insight into its potential use in product development for targeted sensitive groups such as infants and people with special nutritional needs.

Abstract:
Broadleaved forest distribution in Europe and in Latvia is relatively small. Small-leaved lime Tilia cordata Mill. stands are even rarer, so it is important to study and protect them, as well as to assess their biodiversity and future potential. The aim of research is to investigate and assess the vegetation in lime forest stands. In total, 12 plots have been established for long-term monitoring of lime stands. In the sample plots, the survey of growing trees, dead wood, the inventory of vegetation species and the determination of the projective cover were carried out. The natural regeneration of lime was also investigated. During the research it was found out that stock of growing trees does not differ significantly by research objects. It varies from 169 to 446 m3 ha-1. The amount of dead wood in the objects is 0.06 to 56.6 m3 ha-1. The objects mainly contain debris of the II and III degrees of decomposition. The number of vegetation species found in the research objects varies from 21 to 35 species. A total of 26 species characteristic of European broad-leaved forests can be found in the objects. The projective cover of the tree, shrub and herb layers does not differ significantly from measurements in 2018. Small-leaved lime stands are stable and have continuous regeneration of lime trees under forest canopy.

Abstract:
Immediately after the Czechoslovak legionnaires got involved in the Russian Civil War, a legal confusion arose in their ranks. Although their own military courts were slowly being established, the Czechoslovak Army Corps was fragmented throughout Siberia into several groups that were in minimal contact with each other and in varying states of organization. The commander of one of these groups was the ambitious officer Radola Gajda who, depending on whether we believe the testimony of his officers or not, either did not receive or ignored the order to create a unified court system and instead created his own, the so-called Special Court Martial. This paper deals with the functioning of this specific judicial body, which became known for the arbitrariness of its decisions and draconian punishments. The result of an investigation that was later ordered to clarify the courts legitimacy and mitigate some of the punishments will also be described.

Academy of Music, Theatre and Fine Arts, Republic of Moldova, 2025. https://doi.org/10.55383/ca2025.12.

Full text
Abstract:
Painting on pure silk is a genre of fine art characterized by the clarity and transparency of colors. The pearlescent effect of pure silk adds value to the created work. The salt is applied on painted silk while it is still wet. In this way there can be produced extremely attractive effects, though not completely controllable at the first stage of the work. The increased absorption property of salt represents an essential advantage in this technique. The moisture absorbed by the grains of salt partially dissolves the paint leaving marks on the fabric. They create, as a whole, lines and stains, conditioned by the structure and properties of the silk. Salt has two essential properties of manifestation on the painted surfaces. It can be used to lighten the color, and it can break down the mixed pigments into their basic components. Bassarabian artists such as Alexandr Drobaha, Vasile Grama, Ala Uvarov, etc., starting with the 70s-80s of the 20th century, implemented special effects with salt in their silk painting artworks. Painting on pure silk with salt effects offers unlimited possibilities for artistic experimentation.

Full text
Abstract:
This special report describes the first phase of developing an ecological model to inform marine bioinvasion risks in the United States. The project responds to the needs of the US Army Corps of Engineers (USACE) Aquatic Nuisance Species Research Program, or ANSRP, which addresses all problematic invasive aquatic species affecting the nation’s waterways, infrastructure, and associated resources, and the needs of the USACE navigation and dredging programs. Multiple port-deepening studies are either in progress or under consideration, and all must address ecological risk. Understanding whether and how increased dredging contributes to increased marine bioinvasion risk allows risk mitigation during early planning phases. Considering the potential impacts of future environmental change, such as changing sea level, ocean temperature, and ocean chemistry, will further strengthen planning for marine bioinvasion risk. Therefore, this special report documents current ecological modeling approaches to marine bioinvasion risk models and identifies models that incorporate shipping as a vector. The special report then presents a conceptual model and identifies historic vessel position data from the Automatic Identification System, or AIS, now available for most commercial and some recreational vessels around the United States, as a key source for future model development and testing.

Full text
Abstract:
This special report reviews current scientific literature to identify the most commonly cited metrics used to describe the macrohabitat criteria important for Chiroptera presence in the United States. The review evaluates 69 scientific articles from 1994 to 2018. The most commonly cited metrics were divided into four main categories: tree-species-level metrics, landscape-level metrics, distance metrics, and topographic and atmospheric metrics. Of all metrics found, the top six most common metrics noted across all articles were percent canopy cover, diameter at breast height (DBH), forest type, distance to water, distance to roads or other urban features, and tree density. In addition, 27 of the 47 (57%) bat species located within the United States were represented. These metrics provide important insight into the regional or national species-level distribution and assist with modeling the relationship between species distribution and habitat change.

Full text
Abstract:
Breeding colonies of wading birds (orders Ciconiiformes, Pelecaniformes) and seabirds (orders Suliformes, Pelecaniformes) serve as important indicators of aquatic ecosystem health, as they respond to changes in food abundance and quality, contaminants, invasive species, and disturbance. The Comprehensive Everglades Restoration Plan, Restoration Coordination &amp; Verification program (CERP-RECOVER) has identified wading-bird colonies as an important ecosystem restoration indicator. The National Park Service South Florida/Caribbean Inventory &amp; Monitoring Network (SFCN) ranked colonial nesting birds eighth out of 44 vital signs of park natural resource conditions for ecological significance and feasibility. However, while large-scale monitoring efforts are occurring in the rest of the Greater Everglades Ecosystem, only minimal historic data collection and no extensive ongoing monitoring of wading bird and seabird nesting have occurred in Biscayne National Park. Consequently, due to their high importance as biological indicators and because they are a gap occurring in regional monitoring efforts, the network has initiated a monitoring program of colonial nesting birds in Biscayne National Park. This protocol provides the rationale, approach, and detailed Standard Operating Procedures for annual colonial bird monitoring within and close to Biscayne National Park and conforms to the Oakley et al. (2003) guidelines for National Park Service long-term monitoring protocols. The specific objectives of this monitoring program are to determine status and long-term trends in: Numbers and locations of active colonies of colonial nesting birds with a special focus on Double-crested Cormorants, Great Egrets, Great White Herons, Great Blue Herons, White Ibises, and Roseate Spoonbills. Annual peak active nest counts of colonial nesting birds in Biscayne National Park with a special focus on the species mentioned above. An annual nesting index (i.e., sum of monthly nest counts) with a special focus on the species mentioned above. Timing of peak nest counts for the focal species.
