Benzylideneanilines, the condensation products of benzaldehyde and aniline derivatives, have enjoyed significant success as optical metal ion sensors due to their ability to form stable metal complexes which exhibit distinct spectral features compared to the unbound compound. However, their use in aqueous media is limited by the hydrolytic susceptibility of the C=N moiety. Hence, an in-depth investigation into the hydrolytic degradation mechanism of a series of 2-aminophenol derived Nbenzylideneanilines was conducted wherein molecular modelling techniques were applied to elucidate the “step-by-step” transformation mechanism of these compounds from a fundamental perspective.
Piano grass (Themeda arguens), reputed to have been introduced to Jamaica as packing material in an imported piano1 . There are about 27 varieties of this highly invasive grass/weed worldwide and in Jamaica the species previously identified as Themeda arguens is of concern as it has progressively taken over lawns, pastures and roadsides . The grass is of particular concern to livestock farmers due to its highly invasive and aggressive nature and the concomitant negative effect on livestock productivity, especially during its annual seeding period (November/December – April) , when the palatability of the grass diminishes significantly and the seed awns can cause severe damage to the mouth when consumed, and feet of livestock , sometimes requiring veterinary intervention.
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.

The worldwide ginger market was valued at US$6.82 billion in 2020, with India, Nigeria and China being the top global producers (Global Ginger Market Report, 2021). Jamaican ginger once held pride of place in the global market, with its widely accepted superior quality, uniqueness of flavor and high oil content. However, since the initial outbreak of the ginger rhizome rot disease in 1995, production has drastically plummeted to insignificant levels and the industry has not yet recovered. In this regard, a number of intervention strategies have been implemented by the Government of Jamaica over the years, including the Eastern Jamaica Agricultural Support Project of 1993 under RADA, the Ginger Agricultural Science, Technology and Innovation Working Group initiative supported by the CTA ACP-EU under the National Commission and Science and Technology in 2005, the Ginger Resuscitation and Expansion Programme of 2011 led by the Export Division of the Ministry of Agriculture, the Ginger Value Chain Study supported by the FAO, the Ginger Varietal Study funded through the Jamaica Business Development Fund in 2018 and the ongoing Ginger Value Chain and Certification Programme supported by the FAO, with propagation and production of disease-free planting materials. These programmes, amounting to investments of millions of dollars, through partnerships with the key private, governmental and international stakeholders, have been met with varying degrees of success.
