Impatiens Parviflora

Abstract Biological invasion as one of the main threats to natural ecosystems has big economic impact on conservation of nature. Studies of the population biology of invasive species may allow more precise focus on specific plant and soil characteristics involved in invasiveness. The aim of the study was to investigate the relationship between selected biological population characteristics of Impatiens parviflora and a few chosen chemical and physical soil features. Sites were selected because of the poor mapping of invasive plants in the protected natural areas and their interactions with specific soil characteristics. Research on I. parviflora was realised during a vegetation season in three forest nature reserves in Prešov district, Slovakia. Some population biological characteristics of I. parviflora as one of the most invasive plant species in Slovakia and Central Europe were surveyed. The correlation between the numbers of plants was analysed, as well as select population biological characteristics of I. parviflora (plant height, width of the largest leaf and the number of flowers/fruits) on some select chemical and physical soil attributes (soil pH, bulk density, porosity and soil moisture) were analysed. The results suggest that biological characteristics of I. parviflora in three different microhabitats – a meadow (a habitat without tree vegetation), a habitat close to the stumps and a habitat under dense tree vegetation seemed to influence the selected soil parameters. Our results showed that I. parviflora prefers acidic and non-compacted soil conditions. Sunlight and soil moisture do not show statistically significant differences on any biological characteristic of the population. The results also suggest that the autecology of I. parviflora in Western and Central Europe is not very well known and deserves further study.

AbstractForensic taphonomy is a branch of forensic science which in its application uses processes related to the decomposition of corpses and uses soil evidence to estimate post-mortem interval (PMI) or post burial. Soil has evidential value because it contains minerals, plants and animal materials that are useful for characterization. This research was conducted by analyzing soil characteristics, namely soil pH and soil moisture and total nitrogen content in soil samples taken from under rabbit carcasses that were placed on the soil surface, buried 25 cm and 50 cm at each decomposition stage. The results obtained showed significant differences at each stage of decomposition and laying of the carcasses.

Abstract Accurate and timely information on soil moisture conditions is an important component to effectively prepare for the damaging aspects of hydrological extremes. The combination of sparsely dense in situ networks and shallow observation depths of remotely sensed soil moisture conditions often force local and regional decision-makers to rely on numerical methods when assessing the current soil state. In this study, soil moisture from a commonly used, high-resolution reanalysis dataset is compared to observations from the U.S. Climate Reference Network (USCRN). The purpose of this study is to evaluate how well the North American Regional Reanalysis (NARR) captured the evolution, intensity, and spatial extent of the 2012 drought using both raw volumetric values and standardized anomalies of soil moisture. Comparisons revealed that despite a dry precipitation bias of 22% nationally, NARR had predominantly wetter 5-cm volumetric soil conditions over the growing season (April–September) than observed at USCRN sites across the contiguous United States, with differences more pronounced in drier regions. These biases were partially attributed to differences between the dominant soil characteristics assigned to the modeled grid cells and localized soil characteristics at the USCRN stations. However, NARR was able to successfully capture many aspects of the 2012 drought, including the timing, intensity, and spatial extent when using standardized soil moisture anomalies. Standardizing soil moisture conditions reduced the magnitude of systematic biases between NARR and USCRN in many regions and provided a more robust basis for utilizing modeled soil conditions in assessments of hydrological extremes.

In the face of rapid global change it is imperative to preserve geodiversity for the overall conservation of biodiversity. Geodiversity is important for understanding complex biogeochemical and physical processes and is directly and indirectly linked to biodiversity on all scales of ecosystem organization. Despite the great importance of geodiversity, there is a lack of suitable monitoring methods. Compared to conventional in-situ techniques, remote sensing (RS) techniques provide a pathway towards cost-effective, increasingly more available, comprehensive, and repeatable, as well as standardized monitoring of continuous geodiversity on the local to global scale. This paper gives an overview of the state-of-the-art approaches for monitoring soil characteristics and soil moisture with unmanned aerial vehicles (UAV) and air- and spaceborne remote sensing techniques. Initially, the definitions for geodiversity along with its five essential characteristics are provided, with an explanation for the latter. Then, the approaches of spectral traits (ST) and spectral trait variations (STV) to record geodiversity using RS are defined. LiDAR (light detection and ranging), thermal and microwave sensors, multispectral, and hyperspectral RS technologies to monitor soil characteristics and soil moisture are also presented. Furthermore, the paper discusses current and future satellite-borne sensors and missions as well as existing data products. Due to the prospects and limitations of the characteristics of different RS sensors, only specific geotraits and geodiversity characteristics can be recorded. The paper provides an overview of those geotraits.

Soil fertility level improvement in an environmentally friendlier way has been a key to provide a sustainable cocoa production. Earthworms, as decomposeragents in soil, may provide a sustainable way of improving soil fertility level. The objective of this study was to quantify top soil earthworm population andsome important soil characteristics, e.g. soil moisture, organic C, total N, and pH to see if there was any response observed due to different level and type oforganic waste applications. Their surface populations, i.e. at 5–10 cm depth, within cocoa circle were investigated with respect to different type of organic wasteapplications, i.e. cocoa pod waste, cocoa leaf waste, and sheep manure. For cocoa derived organic matter, the level of application was arranged at 5, 10, and 20 ton/ha to obtain an optimal condition at which the highest population of earthworm is obtained. A field investigation was performed at a square of 900 cm2 sizedarea, and extending down to 5–10 cm depth. Additionally, the effect of organic waste to top soil characteristics were also determined mainly to some importantparameters such as soil moisture, organic carbon, total nitrogen, and soil pH (H2O). Our analysis suggest that field heterogeneity condition may limit the conclusion, mainly related to the question of to what extent the effect of organic wastes to the changes in terms of soil characteristics. The application of organic wastes was able to increase the population of earthworms. Their highest abundance was obtained following the application of cocoa pod at 20 ton/ha, which was about 5 times higher than the population in the control.
