Oil palms in parts of the oil palm belt in the Gold Coast Colony have suffered at intervals from the attacks of a leaf-mining beetle. Specimens of the adult beetle and full-grown larva were sent by Mr. W. H. Patterson, Government Entomologist to the Gold Coast, to the Imperial Bureau of Entomology in 1920. These were determined by Mr. S. Maulik as a new species of the genus Coelaenomenodera (family Hispidae) and described under the specific name elaeidis (Bull. Ent. Res., x, p. 171). This species is indigenous to the West Coast of Africa, and hitherto has not been recorded outside the Gold Coast, but no doubt occurs throughout the West Coast oil palm belt. According to Mr. Maulik, 32 species of this genus are known, of which four only are recorded from Africa, the remainder being from Madagascar.

Humping/hollowing and flipping are land development practices widely used on the West Coast to overcome waterlogging constraints to pasture production. However, there is very limited information about how the resulting "new" soils function and how their properties change over time following these extreme modifications. We hypothesised that soil quality will improve in response to organic matter inputs from plants and excreta, which will in turn increase nutrient availability. We tested this hypothesis by quantifying the soil organic matter and nutrient content of soils at different stages of development after modification. We observed improvements in soil quality with increasing time following soil modification under both land development practices. Total soil C and N values were very low following flipping, but over 8 years these values had increased nearly five-fold. Other indicators of organic matter quality such as hot water extractable C (HWC) and anaerobically mineralisable N (AMN) showed similar increases. With large capital applications of superphosphate fertiliser to flipped soils in the first year and regular applications of maintenance fertiliser, Olsen P levels also increased from values

In Gold Rush–era California, banking and the financial sector evolved in often distinctive ways because of the Gold Rush economy. More importantly, the abundance of gold on the West Coast provided an interesting test case for some of the critical economic arguments of the day, especially for those deriving from the descending—but still powerful—positions of the “hard money” Jacksonians.

As práticas de campo proporcionam aos discentes uma proximidade com o cotidiano. A metodologia proposta no estudo sugere uma divulgação simplificada do conhecimento cientifico da Planície Litorânea de Almofala, propondo rotas de acesso didáticas para práticas de campo que auxiliem os professores das escolas de Itarema. Para a complementação teórica foram considerados como base os inventários da Geodiversidade cientifica do litoral oeste do estado do Ceará, realizados no âmbito do projeto PRONEX. Isso foi feito por pesquisadores de várias Instituições de Ensino Superior do Ceará, e a literatura clássica local. Enquanto resultados discutidos, considerou-se que estes roteiros de práticas de campo podem ser estabelecidos e decididos em conjunto, entre professores e alunos. Tendo como base o mapa interpretativo dos roteiros, com intuito de realizar o reconhecimento e entendimento da dinâmica costeira.Palavras-chave: Educação; Geodiversidade; Planície Litorânea. ABSTRACTField practices provide students with a closeness to daily life. The methodology proposed in the study suggests a simplified dissemination of scientific knowledge of the Almofala Coastal Plain, proposing didactic access routes for field practices that help teachers of Itarema schools. For theoretical complementation, the inventories of the scientific geodiversity of the west coast of the state of Ceará, carried out under the PRONEX project were considered. It was done by researchers from various Higher Education Institutions in Ceará, and its local classical literature. As results discussed, it was considered that these field practice roadmaps can be jointly established and decided between teachers and students. Based on the interpretative map of the roadmaps, in order to recognize and understand the coastal dynamics.Keywords: Education; Geodiversity; Coastal plain. RESUMENLas prácticas de campo ofrecen a los estudiantes una cercanía a la vida diaria.

En cuanto a los resultados discutidos, se consideró que estas hojas de ruta de prácticas de campo pueden ser establecidas y escogidas conjuntamente entre docentes y estudiantes, con base en el mapa interpretativo de ruta, con el fin de reconocer y comprender la dinámica costera de esta región.Palabras clave: Educación; Geodiversidad; Llanura costera.
