Abstract Rough harvester ant control was evaluated in an urban forest park in the city of Albuquerque. Treatments were randomized within blocks and replicated 4 times. Ant mounds were checked for activity, selected and marked, and counts made of active ants on and in the clear area of each mound prior to treatment. Treatments were made on 2 June under sunny weather conditions while ants were active (7:30-11:30 a.m.). Broadcast granular treatments were made by applying measured amounts to a 100 ft2 area around each mound with an Ortho® Whirly-Bird® granular applicator. The broadcast spray treatment was applied with a CO2 pressured back-pack, small-plot sprayer with 6 X-4 tips spaced 20 inches apart. At 60 psi and 4 mph the sprayer delivered 5.63 gal of finished spray per acre. However, the 10 ft by 10 ft (100 ft2) area around each plot was sprayed in each direction to give a spray volume of 11.3 gal per acre. Dry Mound (M) treatments were made by sprinkling measured amounts of each form on the mound area around the entrance hole only. The Orthene 75SP mound drench was applied in 3.78 liters of water sprinkled over a 0.37 m2 area around the center of each mound.

Palembang City is one of the big cities in Indonesia. Along with the increasing population and the increasing number of motorized vehicles, it will certainly have an impact on the increasing number of traffic accidents in the city of Palembang. In this study, the writer will determine the pattern of traffic accidents by using the fp-growth algorithm and using various variables. The variables that will be used consist of weather, time of incident, road geometry, profession, level of injury. This research is expected to be a reference for the police to be able to take anticipatory measures in order to reduce the number of traffic accidents in the Palembang City area. The fp-growth algorithm can be applied properly to determine the pattern of the causes of traffic accidents in the city of Palembang by using 2 minimum support of 40% and 50% and 2 minimum confidence of 70% and 90%. Based on the resulting rules, there are rules with the highest confidence value of 98% with these rules: When an accident occurs with a Side-Side accident type, the accident occurs in sunny weather conditions

Abstract. Berame JS, Elazegui EP, Arenas MC, Orozco JA. 2021. 2021. Microclimatic factors and soil characteristics of Arroceros Forest Park in the City of Manila, Philippines. Biodiversitas 22: 4956-4962. Microclimatic factors affect many ecosystem functions. However, the challenge of acquiring consistent data has impeded the quantitative assessment of the spatial heterogeneity of soil-climate in Arroceros Forest Park as an artificial urban forest park known as the last lung of the City of Manila. With this unassisted urban forest park, this study aims to determine the microclimatic factors such as light intensity, air temperature, air humidity, wind speed and direction, soil temperature, soil pH, percent organic matter, percent soil moisture and soil texture by using a sieve analysis and textural triangle method to know the status of the forest park. These procedures reveal the soil type available in the park to be clay and loam suitable for growing plants abundantly. Results showed that four microclimate factors viz. air temperature, air humidity, percent organic matter, and soil texture, were highly significant (p<0.000). Additionally, it further revealed that microclimatic factors such as light intensity, wind speed, and soil pH are essential in an ecosystem. It also found that soil size is a significant parameter for soil characterizations in this kind of study. Finally, the division of soil microsites into different positions based on prevailing light or shade conditions helped assess the significant variations of soil characteristics and conditions within the study area.

Artificial Neural Networks (ANNs) have proven to be a powerful tool for solving a wide variety of real-life problems. The possibility of using them for forecasting phenomena occurring in nature, especially weather indicators, has been widely discussed. However, the various areas of the world differ in terms of their difficulty and ability in preparing accurate weather forecasts. Poland lies in a zone with a moderate transition climate, which is characterized by seasonality and the inflow of many types of air masses from different directions, which, combined with the compound terrain, causes climate variability and makes it difficult to accurately predict the weather. For this reason, it is necessary to adapt the model to the prediction of weather conditions and verify its effectiveness on real data. The principal aim of this study is to present the use of a regressive model based on a unidirectional multilayer neural network, also called a Multilayer Perceptron (MLP), to predict selected weather indicators for the city of Szczecin in Poland. The forecast of the model we implemented was effective in determining the daily parameters at 96% compliance with the actual measurements for the prediction of the minimum and maximum temperature for the next day and 83.27% for the prediction of atmospheric pressure.

Urban forests offer multiple functions: they can balance negative effects from the environment and provide the public with a place for leisure and recreation. Hence, urban forests are crucial to urban ecology and have been widely studied. In addition, relevant study results were applied for policymaking in urban development and forest park management. This study evaluated the ecological value of the Sinhua Forest Park and examined whether the socioeconomic background of participants influences their willingness to pay (WTP) for ecological conservation. Questionnaires were distributed to visitors in the Sinhua Forest Park in Tainan, Taiwan, and the payment card format of the contingent valuation method was employed to evaluate the ecological value. The results showed that the visitors had an annual WTP of $22.01 per person. However, when samples with protest responses were excluded, the WTP rose to $24.58. By considering the total number of visitors of a year, the total ecological value was $1,426,964.14/year and reached $1,593,257.31/year after excluding the protest samples. This study also analyzed participants’ within-variable socioeconomic background (e.g., gender and education) and discovered that male participants who are aged 60 years or older, with an education level of senior/vocational high school, and those who visited green spaces two to three times per week presented a high WTP score on average. A Tobit regression model was employed for examination, and the results indicated that participants’ education and frequency of visiting green spaces significantly influenced their WTP for the ecological conservation of the Sinhua Forest Park.

Knowledge about urban forests in Poland is still limited, as it is primarily based on aggregate, formal data relating to the general area, ignoring the spatial dimension and informal green areas. This article describes and analyses spatio-temporal changes in the actual urban forest resources in Wrocław in 1944–2017, which covers the first period of the city’s rebuilding after its destruction during World War II and its development during the nationalised, centrally-planned socialist economy, as well as the second period of intensive and only partly controlled growth under conditions of market economy. The study is based on current and historical orthophotomaps, which were confronted with cartographic data, as well as planning documents. We found that between 1944 and 2017, the percentage contribution of informal woodlands increased tenfold (from 0.5 to 4.9% of the present total area of the city). The area occupied by such forests has grown particularly during the most recent years of the city’s intensive development. However, the forests have been increasingly fragmented. During the first period, new forest areas were also created in the immediate vicinity of the city centre, while during the second one, only in its peripheral sections. The post-war plans regarding the urban green spaces (UGS), including the current plan, are very conservative in nature. On the one hand, this means no interference with the oldest, biggest, and most valuable forest complexes, but on the other hand, insufficient consideration of the intensive built-up area expansion on former agriculture areas. Only to a limited extent did the above-mentioned plans take into account the informal woodlands, which provide an opportunity for strengthening the functional connectivity of landscape.

This article examines the travel behavior of middle-class women in Dhaka, the capital city of Bangladesh and one of the world's largest and most densely populated cities. In particular, we focus on women's use of non-motorized rickshaws to understand the constraints on mobility for women in Dhaka. Primary research, in the form of an empirical study that surveyed women in six neighborhoods of Dhaka, underpins our findings. Our quantitative and qualitative data presents a detailed picture of women's mobility through the city. We argue that although over 75 percent of women surveyed chose the rickshaw as their main vehicle for travel, they did so within a complex framework of limited transport options. Women's mobility patterns have been further complicated by government action to decrease congestion by banning rickshaws from major roads in the city. Our article highlights the constraints on mobility that middle-class women in Dhaka face including inadequate services, poorly maintained roads, adverse weather conditions, safety and security issues, and the difficulty of confronting traditional views of women in public arenas.

In the article the system of indicators for assessing the balanced functioning of the complex green zone of the city are suggested and substantiated in accordance with the concept of sustainable development. There are distinguished three groups of criteria: ecological, social, and economical. In accordance with each group of criteria there are criteria categories suggested: bioecological, geoecological, landscape and climate-regulating - ecological group; recreational, educational-cultural, and quality of life - social group; market-based and planning - economical group. Each category corresponds to the system of indicators: 27 indicators for the ecological group criteria, 20 for social and 9 for the economical group. The suggested approach to differentiating the criteria for the assessment of the sustainable functioning of the complex green zone of the city allows to summarize and integrate the data about the green zone of the city, define its strong and weak points, and develop a plan for the management of its territories and  increase resilience to human induced pressures. The assessment of the balanced functioning of the complex green zone of Ternopil city was carried out in accordance with the functional-territorial approach. The main geospatial parameters have been defined: deficit of green planting of the forest-park area of CGZC is 614.5 ha, forestry - 2889.5 ha., the deficit of green planting of restricted use is 12 ha, green planting of special-purpose - 62.5 ha., the level of the greening of the city neighborhoods is 4.5 m2/person (at a standard of 6 m2/person). Based on the results of the functional parameters calculations it has been established that  to «provide oxygen» to the residents of Ternopil it needs to increase the area of forests in the forest-part district of CGZC by 83.5 ha to ensure the optimal indicators of recreational capacity of this area, it is essential to increase the area of parks by 90 ha and forests by 965 ha. In Ternopil, the speed of the maximum flow is 6 million m3/hour with the rainfall intensity of 55 mm/hour, while the sewerage network of the city can only handle the flow of 30 thousand m3/hour . Therefore, it could be argued that the complex green zone of Ternopil city is characterized by the imbalance of the main functional-territorial parameters and requires the implementation of the optimization measures.. Key words: sustainable development, complex green zone of the city, indicators, normative parameters, city of Ternopil.

Introduction. Biometeorological circumstances have a big influence on all traffic participants, especially reflexes, moving coordination and perception ability. With a lower attention and drivers? and pedestrians? concentration, there was a larger amount of pedestrian trauma in certain biometeorological phases. Objective. The aim of this study was to establish the correlation between pedestrian trauma and biometeorological phases. Methods. The comparative analysis of everyday biometeorological phases for the city of Kragujevac determined by RHMI and the evidence of knocked-down pedestrians from the Kragujevac traffic police for the period 2003-2008. Results. There were 6,127 accidents, with 696 knocked pedestrians in 666 (10.87%) accidents. Most of them happened in 2003 (135), and the fewest in 2005 (90). Most accidents were during December (74), the fewest were in June (46). The fewest accidents were during 04-05-06 hour interval (by 2), most during 13-14 hours (61). There were 374 males and 349 females. Most of the males (by 60) were 0-10 and 11-20 years old, most of the females (74) were 11-20 years old. There were 443 pedestrians who suffered slight body injuries (112 were 11-20), 225 suffered heavy and 28 had lethal injuries (most over 70). As provokers, the pedestrians suffered because of improper crossing roads (185), while as a casualties, they suffered due to speeding of vechicles (285). Most accidents happened in biometeorological phases 4 (168) and 9 (151), the fewest in phase 10 (4). Conclussion. Statistical analysis shows a significant correlation between pedestrians? accidents and biometeorological phases, when the most accidents occurred during penetrations of cold fronts, while there was a sudden switch of weather conditions from warm-dry to cold-wet weather.
