Microtopography-Induced Differentiation of Moss Synusiae in Wet Grasslands Covering a Karst Plain in Central Italy (Pian Grande, Central Apennines)
No full textThis study examines the relationships between the occurrence of epigeic moss assemblages in different grasslands and the microhabitats (pits, dolines, brooks and mounds) occurring in a karst, almost flat basin. The bryophytes tend to form specific synusiae in grassland communities that cover particular microhabitats differentiated on the basis of microtopography. Except for pits and mounds, all other microhabitats are clearly distinguishable in terms of bryophyte composition. The most discriminant species between the moss synusiae of dolines, brooks and pits are Drepanocladus aduncus, Fontinalis antipyretica and Polytrichum commune, respectively. The mounds have no differential species and are poorly distinguished from pits based only on the low cover of Polytrichum commune. A combined soil acidity-moisture gradient determined by both land microtopography and surface water runoff is responsible for the good compositional distinctiveness of dolines and brooks from pits and mounds. A relatively broad section of this gradient is occupied by the niche of Calliergonella cuspidata, which could be the indicator of a different synusia occurring in microhabitats with ecological conditions intermediate between dolines and brooks. A weaker gradient of soil organic matter content accounts for the distinction of pits from dolines and brooks in the species multidimensional space. Overall, there is a good Agreement between the structure of epigeic bryophyte assemblages and the corresponding type of vascular plant communities developed in the same karst habitat, which supports the hypothesis of their dependence and the methodological approach of integrated releve ́s in phytocoenosis sampling

Dietary Shift in a Barn Owl (Tyto alba) Population Following Partial Abandonment of Cultivated Fields (Central Apennine Hills, Italy)
No full textWhile most studies focused on the impact of intensive agriculture on the barn owl’s diet, little is known about the effect of cropland abandonment. We compared the taxon composition/evenness and feeding guild structure of small mammal prey identified in pellets collected before (2004) and after (2012) the abandonment of 9% of cultivated fields within a cultural landscape. Data on prey abundance per pellet were analysed through non-metric multidimensional scaling and permutational, paired tests. Prey taxon evenness in 2012 was significantly lower than in 2004. That induced a shift in prey taxon composition as indicated by the significantly lower dietary similarity compared with the random expectation. The increasing and declining abundance of Murinae and Crocidurinae, respectively, had the largest contribution to the differentiation of the diet spectrum. Insectivorous prey was significantly more abundant in 2004 compared to 2012, while the opposite was true for omnivorous prey. Our results suggest that even a small fraction of abandoned crops in the landscape might induce a detectable shift in the barn owl’s food niche. The dietary effects are similar to those observed after agricultural intensification, that is, an increase in the abundance of generalists to the detriment of specialist mammal prey
Do species incidence matrices reflect different degrees of plant community integration?
No full textBackground and aims – Assuming the asymmetrical hump model of the stress-gradient hypothesis, higher degree of species aggregation in floristically similar communities is expected under conditions of stronger environmental severity. Methods – Several species incidence-based metrics were calculated for two large, homogeneous matrices pertaining to predefined community types: weed assemblage of trampled sites (S-P) and nutrient-rich pastures (F-A). For each metric and matrix, a standard effect size (SES) was estimated through a null model with fixed species frequencies and equiprobable sites. Key results – All metrics related to co-occurrence, nestedness and clustering of species range boundaries have significant SES in both matrices, but they are all larger in S-P. No significant checkerboardness was detected in S-P, whereas F-A displays non-random segregation patterns that are exclusively due to species turnover. The core species effect is positive but not significant in S-P, and the between-site pairwise similarities present a monotonic distribution. The higher SES of coherence and the significant SES of homotoneity in F-A make it more clearly delineated as a syntaxon. In fact, between-site pairwise similarities are significantly higher in F-A and their distribution approaches a reversed J-shape. Conclusions – The stronger species association and nestedness patterns revealed in weed assemblages are consistent with the hypothesis of higher community integration in harsh environments. However, the species-rich and productive grassland communities appear overall more structured. Regular and moderate disturbances produced by herbivores may be an important requisite for plant community organisation according to the core-satellite species hypothesis in fertile habitats. Although not a test for inferring underlying ecological processes, the joined use and comparison of complementary, species incidence-based metrics represents a useful exploratory tool for distinguishing between various patterns of species assembly, at least for relatively homogeneous, presence-absence matrices of different plant community types

PERANCANGAN APLIKASI ELECTRONIC MEDICAL RECORD (EMR) PADA INSTALASI RAWAT INAP BERBASIS WEB
No full textPelayanan medik dewasa ini membutuhkan sistem yang lebih efektif dan efisien, baik dalam
penggunaan waktu, tenaga maupun sarana. Dalam pengelolaan rekam medik, kenyataan masih
umumnya penggunaan rekam medik manual yang dinilai tak lagi andal menangani data medik
melahirkan ide konversi rekam medik manual kertas ke rekam medik elektronik karena efektivitas dan
efisiensinya.
Penelitian ini bertujuan menciptakan aplikasi rekam medik elektronik yang lebih dikenal
sebagai EMR (Electronic Medical Record) dari rekam medik kertas di Instalasi Rawat Inap Rumah
Sakit Umum Ananda Salatiga. Rekam medik elektronik dirancang dengan membuat form-form isian
catatan-catatan medik dalam proses perawatan pasien selama dirawat. Data-data medik ini kemudian
disimpan dalam basis data sistem dan dikelola secara digital. Setiap kali pengisian data medik pada
form-form tertentu, sistem akan menghasilkan kode yang membawa informasi khusus.
Pada akhirnya, sistem akan menghasilkan deret kode ICD (International Statistical
Classification of Diseases and Related Health Problems) dari kode-kode yang dihasilkan pada
pengisian form-form catatan medik. Deretan kode-kode ini mampu menggambarkan perkembangan
kondisi pasien dan penanganan medik yang diberikan selama perawatan. Data-data medik yang
tersimpan dapat ditampilkan kembali dalam bentuk catatan medik digital.
Kata kunci: rekam medik, rawat inap, EMR, IC
