Summary: | Abstract Due to the urbanization and human invasion of the natural environments, great changes have been occurred on the food composition and feeding ecology of several animals especially those are sharing human his habitat in fields, wadis and gardens. The desert hedgehogs Paraechinus aethiopicus populations inhabiting different localities in Saudi Arabia were studied by using stomach contents analysis between February 2015 and October 2019. Precise analysis of stomach contents of 55 hedgehogs showed that the food of P. aethiopicus is highly diverse and highly influenced with effect of human on the environment including cooked rice, insects, plant materials, eggshells, worms, garbage and remnants of mammals and birds. Diet composition showed seasonal variations that are apparently associated with changes in the availability of different food items. The present results clearly showed that P. aethiopicus is an omnivorous mammal, capable of adapting to a great variety of dietary compositions in the study sites.
Resumo Devido à urbanização e invasão humana dos ambientes naturais, grandes mudanças têm ocorrido na composição alimentar e ecologia alimentar de vários animais, especialmente aqueles que estão compartilhando seu hábitat humano em campos, wadis e jardins. As populações de ouriços-do-deserto Paraechinus aethiopicus que habitam diferentes localidades na Arábia Saudita foram estudadas usando análise de conteúdo estomacal entre fevereiro de 2015 e outubro de 2019. A análise precisa do conteúdo estomacal de 55 ouriços mostrou que a alimentação de P. aethiopicus é altamente diversa e altamente influenciada com efeito de humanos no meio ambiente, incluindo arroz cozido, insetos, materiais vegetais, cascas de ovo, vermes, lixo e restos de mamíferos e pássaros. A composição da dieta apresentou variações sazonais que aparentemente estão associadas a mudanças na disponibilidade de diferentes itens alimentares. Os presentes resultados mostraram claramente que P. aethiopicus é um mamífero onívoro, capaz de se adaptar a uma grande variedade de composições dietéticas nos locais de estudo. |
