Introduction

For metropolitan cities to maintain their tree diversity, it is essential to evaluate the conservation status of remaining urban forests. This study looked at the structure and composition of forest remnants in four urban parks in Curitiba, Brazil, within the natural range of the montane mixed ombrophilous forest. We allocated 66 100 m² plots and recorded all trees with breast heights of less than 15 cm around their perimeters. 1256 individuals from 44 botanical families and 117 tree species, including three alien species, were identified. The density of trees ranged from 1670 to 2095 trees per square meter, and the density of standing dead trees ranged from 90 to 188 trees per square meter. Our shannon diversity index was between 3.00 and 3.52 natsind 1, which is comparable to other non-urban forest remnants' values. 99 species, or 84.6% of the tree community, were non-pioneer species. 89 spp., and 76% were zoochoric species. The findings of the study contribute to the debate regarding the requirement of integrated as well as specialized measures for the management of urban parks devoted to the preservation of tree diversity in a particular phytoecological formation, taking into account aspects of climate change and human history. The natural compound Betulinic Acid (BA) is well-known for its anti-inflammatory, antiviral, antibacterial, anti-malarial, and anti-tumor effects. BA is an intriguing candidate for novel treatment concepts due to its increased cytotoxicity in tumor cells and induction of cell death in various cancers. In human breast cancer cells, our analyses revealed enhanced cytotoxicity and radiosensitization under hypoxic conditions. The underlying mechanisms are currently unknown. Using microarray technology, we examined BA treated human breast cancer cell lines MDA-MB-231 and MCF-7 under normoxic and hypoxic conditions. In both breast cancer cell lines, hypoxia and BA regulated many genes. Under hypoxia, MCF-7 cells (wtp53) enriched in the p53 pathway, as determined by KEGG pathway analysis.

On ball-milled soils, the total C and N content was determined through dry combustion using a CN elemental analyzer (Elementar Vario El, Heraeus, and Hanau, Germany). The soil did not contain any carbonates, so the total C was the same as the total OC. The pipette method was used to determine the texture of the soil in accordance with DIN ISO 11277. In accordance with DIN ISO 10390, the pH values were measured using 2.5 g of field-moist soil and 6.25 mL of 0.01 M CaCl₂. The soil was first slowly leached with 0.1 M BaCl₂ for CEC determination, with a soil to solution ratio of 1:10. Ion chromatography (850 Professional IC, 237 Metrohm, Herisau, Switzerland) was used to measure the exchangeable K⁺, Na⁺, Ca²⁺, and Mg²⁺ in the filtered extracts, and CEC was calculated as the sum of the exchangeable cations.

Description

A modification of the technique described by Zimmerman et al. was used to separate LOC. In order to break up macroaggregates, 15 grams of soil were sonicated in 75 milliliters of water (Branson Digital Sonifier, Branson Ultrasonics Corporation, Dietzenbach, Germany) at an energy level of 22 J mL. The soil was then wet-sieved with a 63 millimeter sieve to separate sand, silt, and clay sized particles from sized particles from one another. Due to the small size of this fraction (2% of total OC according to Zimmerman, et al.), the original method did not allow for the collection of dissolved OC from the suspension at this stage. The diverse chemical structure it has. Particulate Organic Matter (POM) was separated from sand and stable aggregates using a 1.8 g cm³ sodium polytungstate solution to continue the analysis on the fraction greater than 63 m. The labile OC fraction, which was quantified using mass recovery and the C content of the fraction that was determined as previously mentioned for total OC, is represented by this POM of >63 m. Because there was insufficient material to repeat the fractionation and the distribution of OC among the fractions was starkly different from that of other sample points, three outlier sample units were omitted from the analysis.

Conclusion

Trait Variation–Critical Thermal Maximum (CT_max) we measure CT_max using the same method as. As a measure of CT_max, we used the Loss of Righting Response (LRR). Three to four days prior to the experiments, 222 frogs were kept in a similar photoperiod regime in the field laboratory at 2200 m.a.s.l. (due to logistical issues, 15 individuals were kept for five days; however, CTmax did not differ between these individuals or those who had been acclimated for fewer days). We attempted to maintain similar ambient temperature conditions for all individuals (housed within a range of 16.5°C-18.5°C), despite the fact that we carried out our experiments in a location where fully controlled conditions are difficult to achieve, as von May explained. To prevent desiccation, frogs were placed in a plastic cup containing 1.5 mL of water and placed in a water bath. The water's initial temperature was 17°C and averaged 0.45°C per minute.
