Abstract
Background and Aim: Mangrove forests are unique ecosystems situated at the interface between land and sea, playing a crucial role in environmental protection and sustainability. This study aims to educate researchers and coastal residents about the ecological benefits -conservation, environmental, and habitat- of mangrove forests. The goal is to develop suitable strategies and management practices to preserve these invaluable habitats from further degradation.
Methods: In this study, ten samples were randomly selected. The latitude and longitude of each sample were recorded using GPS, and relevant meteorological data were collected. Field operations commenced with the identification of each sample location, followed by the sampling and recording of vegetative characteristics, including tree height, trunk diameter, diameter of the thickest branch, health status, number of companion plants, and measurements of the number, average height, and color of aerial roots within each one-square-meter sample. Additionally, soil and water samples were collected from each site and sent to a laboratory for analysis of their physical and chemical properties.
Results: The total area of mangrove forests in the Khamir region is 2,046 hectares, with an average density of 1,106 trees per hectare. The average diameter of the thickest branch is 26.8 centimeters, the average trunk diameter at the base is 15.61 centimeters, the average tree height is 2.63 meters, and the average crown diameter is 3.08 centimeters. The average height of aerial roots is 10 centimeters, with an average of 234.95 aerial roots per tree. The average electrical conductivity of water was measured at 40,670 µmhos/cm, while the average pH level was 8.62.
Conclusion: Analysis of variance regarding tree height based on vigor status revealed no significant relationship between tree height, branch diameter, trunk diameter, and vigor. However, a positive correlation was observed between tree vigor and crown diameter growth. Additionally, comparisons of crown diameter, thickest branch diameter, and height based on trunk form indicated that trunk form does not influence crown diameter. The findings also highlight that sodium content and salinity among the soil's chemical and physical properties are particularly significant.

Abstract
Background and Aim: Prostate cancer, after lung cancer, is the second most common cancer in men worldwide and the second most common cancer in Iranian men after stomach cancer. To control this disease, methods with minimal side effects are of particular importance. One such method is the use of medicinal compounds found in natural resources such as medicinal plants. This study aimed to evaluate the effects of methanolic and aqueous extracts of the root of the Tangress plant on prostate cancer cells.
Methods: In this study, the cytotoxic effects of the methanolic and aqueous extracts of the Tangress root were investigated on prostate cancer cell lines (PC3) at concentrations of 1000, 500, 250, 125, 62.5, 31.25, and 15.6 (µg/ml) over 48 hours. The IC50 values of the extracts were determined, and statistical analysis was performed using a two-way ANOVA and independent t-test.
Results: The results showed that both extracts significantly reduced cell viability. The IC50 values for the methanolic and aqueous extracts were 184.8 and 148.8 µg/ml, respectively. The two-way ANOVA test showed that the different concentrations of both extracts significantly differed from the control group (P<0.05). Additionally, the t-test between the two extracts showed no significant difference between their IC50 values.
Conclusion: The findings of this study suggest that both methanolic and aqueous extracts of the Tangress plant root have a considerable inhibitory effect on prostate cancer cells. Given the lack of a significant difference between the effects of the two extracts, both could be potential candidates for further research in prostate cancer treatment.
