Invasive alien species (IAS) are implicated in the extinction or decline of numerous native aquatic species worldwide. Their negative impacts occur through mechanisms including habitat alteration, competition, predation, hybridisation, and the spread of disease (Strayer et al. 2006). Small island ecosystems are most susceptible to the impacts of IAS. Once established, freshwater IAS are difficult to eradicate without negatively impacting native species.

Forensic Crime Scene Investigators (FCSIs) are forensic practitioners who are key components to the investigative process within a legal framework. In fact, the criminal justice system considers the scientific evaluation and forensic evidence collection to be the most significant aspect of any criminal investigation and court cases. Despite this, limited literature exists on the psychological effects experienced by FCSIs from processing gruesome crime scenes on a regular basis.
The malaria epidemic was responsible for about 241 million infectious cases and 627,000 deaths worldwide in 2020. This infectious disease, transmitted by the female Anopheles mosquito, is caused by parasites of the genus Plasmodium namely P. falciparum, P. vivax, P. malariae, P. knowlesi, P. ovale curtisi and P. ovale wallikeri.[2,3] Also, malaria is found predominantly in the highlands of Africa which accounts for more than 90% of infections worldwide. While there has been some success in the treatment of malaria, its eradication has been negatively impacted by insecticide and drug resistance. With emergence of thiosemicarbazone as antimalarial agents, the combination of pyridine and amide or thioamide moieties into one scaffold makes for an interesting target.
Numerous organic chemicals, either directly manufactured or formed as byproducts of other processes, are released into the environment. Once there, many cause adverse effects on environmental and human systems. Of particular concern are long-lasting impacts from those organic pollutants that remain in the environment for long periods of time. The development of appropriate management strategies to address this problem requires knowledge of the environmental distributions of these pollutants.
Vector-borne diseases have since the 17th century been the leading cause of death by disease more than any other causes combined, even preventing development in the tropics (Gubler 1998). Of all insect vectors, Aedes aegypti proves to be the deadliest as it is the primary vector of the four most notorious vector-borne diseases – chikungunya (chik-V), Zika (Zik-V), dengue fever and yellow fever viruses. Control of the spread of Aedesborne diseases is primarily reliant on the control of the vector responsible for their spread. Traditionally, vector control relied on environmental hygiene and the elimination of breeding sites (Gubler 1998), shifting only in the 1980s to the use of synthetic chemicals in the form of carbamate, organochloride, organophosphate and pyrethroid insecticides (Norris, et al. 2015). However, the evolution of Aedes aegypti resistance to synthetic chemicals have made control of the spread of the vector and its diseases increasingly difficult. This led to the exploration of innovative and alternative methods in the control of Aedes aegypti.
