Pinus Jantho Forest (PJF) Nature Reserve has unique characteristics and distinctive ecosystem that plays an important role in the preservation of germplasm and the protection of natural resources. The sustainability of the PJF Nature Reserve is strongly determined by vegetation of its constituents. Therefore, an effort is needed to help its management properly, one of which is by knowing the diversity of plants that make up the community in PJF Nature Reserve. The purpose of this research is to analyze the composition and diversity of plant species in PJF Nature Reserve. Data collection and sampling were done using multiple square method. The plots were laid out by systematic sampling. PJF Nature Reserve composed of 111 species from 46 family. The seedling and understorey have the highest number individuals (1028 in total). Then there are 240 individuals at sapling level, 108 individuals at pole, and 72 individuals for tree.  The Euphorbiaceae family has the largest number of species (11 species). The highest Important Value Index (IVI) for seedlings and understorey, sapling and pole, and tree respectively were Chloranthus elatior (11.09%), Piper aduncum (21.90% and 19.32%), and Pinus merkusii (25.52%). The Diversity Index indicates a high level of plant species diversity (3.25-3.63).

A total of 240 processed broiler carcasses (water-chilled and unfrozen) were each sampled by three methods (whole-carcass rinse, neck-skin rinse, and macerated neck skin) for detection of Salmonella. In addition to this, various procedures were compared: destructive (incubating the entire carcass with the rinse fluid) versus non-destructive (incubating the rinse water with concentrated lactose or selenite cystine broth added after removal of the carcass) sampling and pre-enrichment versus no pre-enrichment during Salmonella detection procedures. There was no significant difference (p < 0.05) between the percentage of Salmonella-positive carcasses obtained by destructive sampling and the percentage obtained by non-destructive samples of whole carcasses. There was also no significant difference (p < 0.05) in results obtained by rinsing and blending excised neck-skin samples. There was highly significant difference (p = 0.001), however, between whole carcass and neck-skin analyses. With whole-carcass sampling, 45% of the carcasses were positive for the presence of Salmonella while with rinsing or blending the neck skin of these same carcasses, only 11% and 12%, respectively, were positive for the organism. Pre-enrichment of the whole carcass, of the whole-carcass rinse, or of the neck-skin samples did not result in significantly greater percentages of positive results than did direct enrichment of these samples.

Boring sponge diversity in the area of the Conero Promontory, the most important rocky emergence on the west coast of the Adriatic Sea (Italy), was assessed. Four species were recorded; one of them,Cliona adriatica, is new and is described here. The new species differs from all the other excavating sponge species, characterized by yellow papillae and lacking or scarcity of microscleres, in the large size of the boring chambers and the presence of numerous styles.Cliona adriaticais present on about 12% of the surface of rocky bottoms in the Conero Promontory area. The impact of this highly destructive species on the carbonatic micritic rock of the promontory was evaluated calculating a relationship between the volume of the boring chambers and the surface of the epilithic portions. Consequently, it was estimated that 1 cm2of epilithic tissue corresponds to 8.5 g of excavated rock. The recorded correlation between the excavated volume and the area of the papillar zone (roughly the area of the substratum affected by the erosion) allows an estimation of the substratum removed by a boring sponge, using only visually oriented, non-destructive, sampling methods.

Pemerihan Resort is a part of the Bukit Barisan Selatan National Park (BBSNP). The area of Pemerihan Resort is also part of a lowland tropical rainforest ecosystem with high carbon stocks and biodiversity levels. However, the biodiversity at Pemerihan Resort is threatened by human activities. The aim of this study is to understand species diversity of trees and the carbon stocks in Pemerihan Resort. The plots used include 5 clusters of the National Forest Inventory (NFI) plots within an area of 1 ha for each plot. Data collection was conducted by a census of all trees in the cluster plots and measurements of the diameters and heights of all trees. The measurements of the tree biomass were conducted by non-destructive sampling methods. The trees measured are ≥ 20 cm only. Species diversity of the trees was analyzed by Shannon-Whiener index. The carbon stock was analyzed using the Indonesian National Standard (SNI) referring to the Intergovernmental Panel on Climate Change (IPCC). The results showed that Pemerihan Resort is a mixed Dipterocarpaceae ecosystem and a type of normal forest. The dominance of Dipterocarpaceae is 38%. Pemerihan Resort has 611 of individual trees within 99 species and 38 families. The Diversity index (H´) of Pemerihan Resort is 2.70. This is a moderately diverse and very stable environment. Tree carbon stock in Pemerihan Resort is 277.64 tons c/ha. The resort is included in the primary dryland category and High-Density forest (HK 3). The results of this study are useful as the basic data in conducting conservation efforts in the BBSNP area.Keywords: Carbon, diversity, tree, species, species, family

Critical Aspects

Abstract Recently, infection transmission risk associated with contaminated, patient-ready flexible endoscopes has attracted attention. Outbreaks of multidrug-resistant organisms resulting in infection and/or colonization have been particularly concerning. Recent CDC and FDA recommendations focus on reducing “exogenous” infection transmission and specifically recommend that endoscopy sites have quality systems in place for endoscope reprocessing. Another key recommendation is the culture of patient-ready endoscopes to detect contamination with organisms of concern. Remaining gaps in the guidelines include ensuring that optimal endoscope-channel sample methods are used and ensuring effective root-cause analysis and remediation when contamination is detected. In this review, we summarize the critical aspects of endoscope sample collection and present a practical approach to root-cause analysis and remedial action plans.
