No \u00e2mbito de trabalhos de monitoriza\u00e7\u00e3o efectuados na Prov\u00edncia de Malange, em Angola, a M\u00e3e d\u2019\u00e1gua colocou diversas c\u00e2maras digitais autom\u00e1ticas no terreno com o objectivo de capturar imagens de mam\u00edferos que permitissem perceber que esp\u00e9cies ocorrem na \u00e1rea de estudo.<\/span><\/p>\n

No primeiro ano foram colocadas apenas 4 c\u00e2maras em 4 locais diferentes e sempre durante per\u00edodos reduzidos. No segundo ano colocaram-se 30 c\u00e2maras em 3 zonas distintas sendo que numa delas as c\u00e2maras permaneceram apenas um dia e nas outras duas estiveram activas durante cerca de 9 dias.<\/span><\/p>\n

\"C\u00e2mara

C\u00e2mara fotogr\u00e1fica autom\u00e1tica<\/span><\/p><\/div>\n

No total obtiveram-se alguns milhares de imagens, muitas delas de mam\u00edferos, algumas de aves e outras de r\u00e9pteis.\u00a0<\/span>Foi poss\u00edvel identificar 14 esp\u00e9cies diferentes de mam\u00edferos, embora as imagens nem sempre nos facilitassem a identifica\u00e7\u00e3o, pois por vezes referiam-se a animais capturados em movimento durante a noite podendo apenas ver-se uma parte do corpo.<\/span><\/p>\n

A esp\u00e9cie mais frequente nas imagens foi o macaco-de-cara-preta (Chlorocebus cynosuros<\/em>) esp\u00e9cie diurna relativamente comum na \u00e1rea de estudo. De entre os ungulados s\u00e3o de referir o hipop\u00f3tamo Hippopotamus amphibius<\/em>, a seixa Philantomba monticola<\/em> e o golungo Tragelaphus scriptus<\/em>.<\/span><\/p>\n

De referir tamb\u00e9m o registo de um serval (Leptailurus serval<\/em>), felino diurno que foi capturado por uma das c\u00e2maras instalado numa zona de bosque aberto queimado recentemente. No total foram identificadas as seguintes esp\u00e9cies para a \u00e1rea de estudo:<\/span><\/p>\n

A utiliza\u00e7\u00e3o de c\u00e2maras autom\u00e1ticas para a detec\u00e7\u00e3o de mam\u00edferos em zonas remotas \u00e9 uma ferramenta indispens\u00e1vel sobretudo quando o tempo dispon\u00edvel para os levantamentos \u00e9 reduzido.\u00a0 As imagens obtidas contribuem de forma decisiva para o conhecimento da fauna que frequenta as \u00e1reas a estudar.<\/span><\/p>\n
