New epilithic Naviculales (Bacillariophyta) from Ivory Coast
Epilithic diatom of the Ivory Coast is very poorly understood, aims of this study are: to document the epilithic diatom diversity from Naviculales. In this study, the epilithic diatoms in the samples collected from ten stations on the Me River between February and July 2012. A total of 56 Naviculales new taxa in 8 families were recorded. The taxonomic composition observed was dominated by Navic...
متن کاملAvian Cestodes of the Ivory Coast
Between 1985 and 1988, the cestodes of 1,252 wild birds (174 species) from the Ivory Coast (West Africa) were collected and studied. Of these birds, 15.7% were parasitized by an estimated 95-100 species of tapeworms, 55 of them having been determined or described. Most of the parasites were found in new hosts, and numerous new geographical records are reported. In general, both the prevalence a...
متن کاملInfrasound from lightning measured in Ivory Coast
Previous measurement campaign, realized in France in 2005, has shown that an infrasound station can clearly measure thunder when lightning occur within 75 km from the station. In this paper, infrasound data recorded in Ivory Coast since 2005 are analyzed and compared to WWLLN data in order to quantify statistically the main trends observed in 2005. The main results are : (1) the (infrasonic) th...
متن کاملGeomagnetic Reversals: Rates, Timescales, Preferred Paths, Statistical Models and Simulations
Paleomagnetic data on geomagnetic reversals are divided into two general categories: times of occurrence, and records of directional and/or intensity changes for transitions at individual locations. Despite considerable efforts expended in acquiring paleomagnetic reversal records, a detailed picture of the reversal process is still lacking, along with any means of clearly identifying when the m...
