Climate change could alter forest disturbances, such as insect outbreaks, invasive species, wildfires, storms, and disease. In the present study, the influence of climate change on the structure and decline of Persian oak in the Zagros forest stands is scrutinized. A regular random sampling with fixed sample plots through two sampling periods was applied in 1998 and 2018. Further, the precipitation, temperature, frost, and relative humidity climatic elements pattern was studied from 1988 to 2018. The cross-sectional of standard-form oak was decreased from 19.2, 23.3, and 24 m3.ha in the first sampling stage to 12.3, 16.8, 17.8 m3.ha in the second sampling in Vizhenan, Chelleh, Ghalajeh, respectively. Levene’s test for equality of variances and mean comparison findings via an independent t-test showed a significant difference between the compared groups in 1998 and 2018. The Mann-Kendall analysis results of climatic elements showed that the precipitation, frost, and relative humidity decreased, and the temperature increased during the study period. Noticeable stability was perceived in the studied indices in the first decade and partially in the second decade, but there were many fluctuations in the third decade. According to the findings, it can be assumed that climate change and the occurrence of severe drought stresses cause oak trees to suffer from physiological vulnerability.

Remote sensing is very important for conservation and biodiversity research and applications. For instance, it can be used for monitoring changes in ecosystems. Objective: The objective of this paper was to analyze the change in the forest landscape of Mikembo Sanctuary between 2002 and 2022 using satellite imagery. Method: Supervised classification by maximum likelihood algorithm was performed and helped to differentiate 3 land use classes. Results: The cartographic and statistical analysis show that land use dynamics of the study area are dominated by an increase in forest and a reduction in bare soil. The forest increases with 0.78 km2 (18.04% of the study area) and therefore had a rate of change of more than 32.25%. Conclusion: It has been demonstrated that the Miombo woodland, specially Mikembo Sanctuary is capable of regenerating naturally or by assisted means. Encouraging people for using alternative solutions is necessary to ensure the sustainable forest management and utilization.

Malaria is transmitted by the Anopheles mosquito. The list of human and zoonotic malaria vectors in Malaysia is being updated in this scoping review. Search were conducted at four electronic bases. Title, abstract, and full-text reviews were used to determine which studies were eligible for further assessment. A total of 631 papers were identified until June 2021, yielded to 30 studies were reviewed. Human malaria vectors in Malaysia are identified as Anopheles maculatus, Anopheles sundaicus, Anopheles balabacensis, Anopheles donaldi, Anopheles campestris and Anopheles flavirostris. Vector for zoonotic malaria are Anopheles balabacensis, Anopheles introlatus, Anopheles cracens, Anopheles letifer, Anopheles donaldi, Anopheles hackeri, Anopheles latens, Anopheles collesi and Anopheles roperi. On the other hand, Anopheles aconitus, Anopheles kochi and Anopheles pujutensis are recognized as the potential malaria vectors. In order to implement effective mosquito control measures, it is crucial to comprehend and be knowledgeable about malaria vector profile. This will help stakeholder to develop and establish holistic and efficient strategy framework for integrated vector management (IVM) and develop new strategies for the elimination of malaria based on available evidence.

The rapid rate of urbanization in third world countries leads to rapid land-use land cover change. Thus, managing the land-use land cover change of the town is important for the proper urbanization process. To analyze the land-use land cover (LULC) change, multi-temporal and high-resolution aerial, geospatial techniques of GIS, remote sensing and satellite imagery methods were used. Results of this study revealed that the LULC coverage of forest, grasslands, and agricultural areas of the town rapidly decreased and converted to built-up areas. To control the rapid LULC change of the town, greenbelt principles have to be promoted. Hence, accordingly, findings of this research conclude that the town administration has to plan to acquire aerial photography of the town every three years to sustain the sustainable development.

For soil erosion modeling, determining sediment transport capacity (Tc) is essential because it plays a key role in sediment detachment, transport, and deposition research. This paper provides insights into the seasonal spatial distribution of sediment transport capacity, excess runoff depth in response to the distribution of precipitation, and land use at a watershed scale, using SCN Curve Number (CN) method, Remote Sensing (RS), and Geographic Information Systems (GIS). Spatial distribution in runoff production on hillslopes and sediment transport are explained. We integrated the effect of slope gradient in the curve number to model the landscape effect on sediment transport. The findings show that seasonal variation in sediment transport capacity is influenced by climate change. During June and October, the transport capacity is higher and coincides with channel areas in the Boubo watershed. Potential applications of this map may help the decision-maker to deal with problems associated with watershed development and management.

Land Use / Land Cover (LULC) changes has been progressive across the globe, causing the alteration and shifting of various land use/land cover features. These changes are caused by natural factors such as extreme environmental conditions, earthquakes, volcanic eruption, flooding and also human factors including agricultural expansion, urban and industrial development of infrastructure. The study combined spatial time series satellite data and field observations to observe the changes which have occurred in the land cover mapping between 1999 and 2007. Land cover features were categorized into Vegetation, Crop/farmland, Settlement, Bare land and Water body. Satellite imagery for the intervening period was used to assess the changes in LULC. LULC classes of Settlements and Bare land recorded an increase of 3.21%, and 33.1%, whereas Vegetation, Crop/farmland and Water decreased by 1.8%, 33% and 2.1% respectively. It was observed that the mean conversional change between 1999 and 2007 was 2148.55 hectares. A total land size of 9297.79 hectares did not undergo any change; conversion into Water body was 417.62 hectares, 7688.56 hectares was changed into Crop/farmland, 1137.76 hectares into Settlement, 337.17 hectares into Bare land, and 1161.65 hectares into Vegetation. It was also observed that the sharp increase in Settlement is as a result of rapid population growth and expansion of infrastructure.

Shipbreaking industry has turned out to be dominant sector in Bangladesh without considering the environmental issues. However, to date, extremely limited studies have been performed to monitor the air and noise level around shipbreaking sites of Bangladesh. This study is conducted to assess the air and noise level with associated health risk vicinity to selected shipbreaking areas of the country. Herein, data on various air pollutants, noise level, and meteorological factors were collected from six prominent shipbreaking yards in Chattogram. Findings of the research work revealed that some air quality parameters and noise level adjacent to shipbreaking areas are exceeded the permissible level set by the WHO. The values of Air Quality Index (AQI) is found in the unhealthy category for human health perspective. The average noise level was also recorded beyond the permissible limit in every sampling sites, following descending order: S3 > S4 > S5 > S6 > S1 > S2. From the statistical analysis, the authors explored that there are significant correlation with poor to strong (0.0.026 to 0.97) among the climatic parameters and air pollutants. Both particulate matters and AQI demonstrate a moderate correlation with the meteorological parameters (humidity and wind speed), and gaseous air pollutants (CO2 and TVOC) also have considerable correlations. The moderate correlation between AQI and noise level is also observed in this study. The authors recommended for effective control actions to alleviate the detrimental environmental pollution arises due to the consequences of shipbreaking activities for ensuring health safety of workers.

Polymesoda spp., which represent bivalves in the mangrove ecosystem, inhabit the mangrove forests of the Indo-Pacific region. They are edible bivalves consumed by inhabitants located around the mangrove forests in the region. The bivalves also have a cultural significance because their shells are used for religious ceremonies on the Yaeyama Islands in Japan. However, detailed studies of these bivalves is scarce and their biology is not well understood. We conducted this study in the mangrove forest along Urauchi River of Iriomote Island, Japan. The spatial distribution patterns of the bivalves and the forest floor environment were surveyed. We used 75 large (10m2 quadrat) plots to survey plant species and above-ground root density, and small (1m2 quadrat) plots to count the number of bivalves and measure median particle diameter, sediment temperature and Oxygen Reduction Potential (ORP) in each large plot. In addition, the relationships between these forest floor environmental factors and the spatial distribution patterns of the bivalves were analyzed. Polymesoda spp. was present in 34 plots. Bruguiera gymnorhiza was dominant in 79.4% of plots. A correlation between the distribution and median particle diameter and ORP and sediment temperature was not found. In 94% of the plots, the above-ground root density was over 50% of the large plot. The relationships between the spatial distribution patterns of the bivalves and plant species and the above-ground root density were revealed.
