This doubles the worldwide number of stomachs sampled, and reveals new feeding habits for this species. The mean number of prey items per stomach was 857 89 (range: 12-238), with fish accounting for 99.3% and cephalopods contributing less than 1% of total prey. Fish otoliths from 15 families and cephalopod lower mandibles from three families were identified, representing 22 taxa. The diet consisted mainly of small mid-water fish, the most numerous being Diaphus sp., Lampanyctus sp. and Melamphaidae species. Myctophids were present in all stranded individuals, followed by Diretmidae, Melamphaidae and Opisthoproctus soleatus, while the remaining fish species were scarce or single occurrences. Consistency of diet in four different years reveals a divergence from all previous records in continental areas, where mainly neritic and shelf-break benthopelagic fish species have been reported. Mid-Atlantic Sowerby's beaked whales' showed dietary plasticity, feeding on the most abundant mid-water groups occurring between 0 and750 m. Trophic level from prey numerical frequency was estimated at 4.4 70.46.
Weight-length relationships were estimated for 27 demersal fish species of the Cape Verde archipelago. Samples were collected in October and November 2000 using longline gear in depths up to 600 m, and occasionally to 1200 m. The b values were within expected ranges, varying between 2.406 and 3.761, except for Syacium micrurum (1.574) and Paraconger notialis (4.476), which presented strong allometries instigated through further analysis. This work revises previous literature in the archipelago and provides the first reference on weight-length parameters for 10 fish species worldwide and for 21 species of the Cape Verde archipelago.
RESUMO:Aedes aegypti é uma espécie de ampla distribuição geográfica, e sua presença foi registrada nas ilhas de Cabo Verde. Pelo fato de a sua bioecologia estar sendo atualmente estudada em várias partes do mundo, e também por ter sido realizado o primeiro registro de uma epidemia de dengue no país, decidiu-se pela realização deste levantamento. O trabalho foi realizado entre fevereiro e março de 2010, quando foram inspecionadas seis das dez ilhas que compõem o arquipélago. Os fatores avaliados durante o levantamento foram número, tipo e localização dos recipientes, assim como a presença das formas larvais de Ae. aegypti. Os resultados demonstraram a presença de 2,4 recipientes/residência inspecionada, registrando-se um total de 118 criadouros, sendo estes mais frequentes nas residências abandonadas. A condição de risco foi significativamente diferente entre as ilhas, sendo superior para Boa Vista. Todas as ilhas avaliadas demonstraram tendência significativa à diminuição do número de criadouros, com exceção da ilha de Fogo (GLM; p ≤ 0.05). Os recipientes mais frequentemente registrados foram os barris (> 50 L) (42.6%), localizados tanto no interior quanto no exterior das residências. Como criadouros, foram registrados com mais frequência os barris (> 50 L), tanques (> 200 L) e tanques plásticos (> 50 L) (Teste t; p ≤ 0.05). PALAVRAS-CHAVE:Aedes aegypti; Cabo Verde; larva; insetos vetores. ABSTRACT:Aedes aegypti is a species of wide geographical distribution, and its presence is registered on the islands of Cape Verde. Because its bioecology is being currently studied in several parts of the world, and since the first record of a dengue epidemic has been accomplished in the country, we decided to conduct this survey. The study was carried out between February and March, 2010, when six out of the ten islands of the archipelago were inspected. The factors evaluated during the survey were number, type and location of containers, as well as the presence of larval forms of Ae. aegypti. Results showed the existence of 2.4 containers/inspected houses, registering a total of 118 breeding sites, which are more common among abandoned buildings. The risk condition was significantly different between islands, being higher for Boa Vista. All evaluated islands showed a significant decreasing tendency of breeding sites, except for Fogo island (GLM; p ≤ 0.05). The barrels were the containers most frequently recorded (> 50 L) (42.6%), located both inside and outside the houses. As breeding sites, barrels (> 50 L), tanks (> 200 L) and plastic tanks (> 50 L) were more common (t test; p ≤ 0.05).
