Climate change is one of the most pressing global environmental challenges, influencing food production, natural ecosystems, freshwater supplies, and human health. Scientific assessments indicate that significant alterations in the Earth's climate system have occurred on both global and regional scales since the pre-industrial era. Human activities are mainly responsible for the observed warming trend of approximately 0.1°C per decade over the last 50 years. This review article explores the effects of climate change on vegetation, including habitat fragmentation, phenological shifts, invasive species proliferation, increased forest fires, pest outbreaks, and species extinctions. Additionally, it examines how vegetation can serve as a mitigator of climate change through carbon sequestration. Trees and plants can capture substantial amounts of carbon dioxide, a primary greenhouse gas, storing it in their biomass and roots. Furthermore, practices such as afforestation, reforestation, and agroforestry enhance carbon storage and contribute to climate change mitigation.

In this study, we evaluate the photocatalytic degradation of benzene in aqueous solutions using palladium catalysts supported on mixed oxides of aluminum, cerium, and zirconium. The process was conducted using UV radiation in both a batch reactor and a solar compound parabolic collector (CPC). The catalysts were synthesized via the sol-gel method and characterized using X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), and Energy Dispersive Spectroscopy (EDS). Significant attention was given to the formation of intermediate products in the photocatalytic process, with total mineralization of benzene achieved within 10 to 15 minutes. Notably, Pd/Al90Zr10 and Pd/Al80Ce10Zr10 catalysts demonstrated superior performance, achieving benzene degradation in just 5 minutes without intermediate product formation. These catalysts were further tested with the solar collector, resulting in complete mineralization within 1 hour.

The present study was conducted to assess the fish biodiversity at Simli Dam, Islamabad. A total of 153 individuals, representing 12 species from 2 families (Cyprinidae and Chandidae), were collected across eight sampling stations. The highest diversity and species richness were observed at site 5, followed by sites 1, 2, and 8, each with comparable species richness. Site 3 exhibited the lowest richness. Cyprinidae emerged as the most abundant family across all sites. Notably, five species, including Punctius ticto, Punctius sarana, Punctius sophore, Barilus vagra, and Tor putitora, were found to be abundant. Among these, Mahasheer (Tor putitora) holds significant commercial value and is rare in the country's water bodies, necessitating the establishment of a sanctuary for its conservation at Simli Dam. The study also revealed an imbalance in the forage and carnivorous fish populations, highlighting the need for stocking carnivorous species in the dam to restore ecological balance.

In recent decades, the protection of Intellectual Property Rights (IPRs) has become central to public policy debates, serving as a crucial economic mechanism that fosters research, development, and innovation. This paper reviews empirical studies examining the relationship between IPR protection and economic growth in both developed and developing countries. The findings suggest that while IPR protection can stimulate innovation and economic growth, its impacts vary depending on a country's level of development. Not all studies find a positive correlation between IPR protection and growth, indicating a complex relationship. Further research is needed to explore these dynamics more comprehensively.

This study examines the relationship between job satisfaction and organizational commitment among sports managers in Istanbul. A sample of 363 sports administrators was selected through a simple random sampling method. A structured questionnaire comprising three sections—job satisfaction scale, demographic questions, and organizational commitment scale—was employed for data collection. The data were analyzed using SPSS 16 software. Results indicate a significant and positive relationship between affective commitment and job satisfaction, suggesting that as sports managers' job satisfaction increases, their affective commitment to their organization also strengthens. These findings underscore the importance of enhancing job satisfaction to foster organizational commitment among sports managers.

The study investigates the bioactivity of various drugs and phenylazo compounds, along with their copper (II) and nickel (II) complexes, on the flour beetle Tribolium confusum. Adult beetles were exposed to different dosages of ibuprofen, naproxen, lornoxicam, and indomethacin, as well as phenylazo compounds. Results indicated significant biological effects, with increased mortality rates corresponding to higher dosages. Lornoxicam showed a 73% mortality rate at a 50µg dose, while its combination with Cu (II) ions resulted in lower mortality. In contrast, ibuprofen combined with Cu (II) ions achieved an 86% mortality rate compared to 41% without the ions. Phenylazo compounds R1 and R2 showed enhanced bioactivity when complexed with metal ions, while compounds R3 and R4 showed decreased effects. Notably, compound R3 achieved 100% mortality at a 30µg dose. This research concludes that these compounds, along with their metal complexes, could serve as effective bioactive agents against pests.
